Technical field

[0001]

　The present invention is a terminal apparatus, base station apparatus, a radio communication system and a terminal device control method.

BACKGROUND

[0002]

　The current network is, of mobile terminals such as smart phones and Future Hong traffic accounts for most of the network of resources. In addition, traffic to the mobile terminal use is, there is a tendency to expand in the future.

[0003]

　On the other hand, for example, transportation system, in accordance with the smart meters, deployment of the monitoring system such as IoT (Internet of a things) service of the device, etc., it is required to correspond to the services with diverse requirements. Therefore, for example, 5G (Generation) (Fifth generation mobile communication) such as the next generation communication standard, in addition to the standard techniques of 4G (4th generation mobile communication), additional high data rate reduction, large capacity, technology to achieve low latency reduction is required. It should be noted that, for the next-generation communications standards, technical study in the Working Group of the 3GPP (3rd Generation Partnership Project) has been promoted. The 3GPP working groups, for example, there is a TSG (Technical Specification Group) -RAN (Radio Access Network) WG (Work Group) or the like 1 and TSG-RAN WG2.

[0004]

　As described above, in order to meet the various services, in the next generation communication system, such as 5G, it assumes the support of many use cases. The use case, for example, eMBB (Enhanced Mobile BroadBand), there are cases that are classified as Massive MTC (Machine Type Communications) and URLLC (Ultra-Reliable and Low Latency Communication).

[0005]

　Further, in such LTE is a fourth-generation communication scheme (Long Term Evolution), hybrid automatic repeat request in order to achieve efficient data transmission (HARQ: Hybrid Automatic repeat request) technique is employed. In HARQ, the receiving device, for example, the retransmission of the data that could not be correctly decoded in the processing of the layer 1 protocol layer of the LTE, etc., and requests the transmitting apparatus side. Transmitting device side, when data retransmission is requested, transmitting a retransmission data corresponding to the retransmission request of the original data can not be correctly decoded at the receiving apparatus. In the receiving apparatus side, the data could not be decoded correctly, by combining the retransmitted data, decoding the data. Thus, highly efficient and highly accurate retransmission control is realized. The receiving apparatus side, the Ack information when normally decoded, by transmitting the information of Nack to the transmission device if it can not successfully decoded, thereby realizing a retransmission request.

[0006]

　The feedback information of the LTE of the Ack / Nack, for example, is done in the 14 symbol TTI (Transmission Time Interval) per 1bit.

[0007]

　Further, in the next generation 5G NR (New Radio), Ack / Nack feedback information code block group (Code Block Group: CBG) Introduction of be performed in units are agreed. Incidentally, the feedback information of Ack / Nack using CBG is carried out in per CBG unit 1bit. Further, each of the number of symbols for transmitting feedback information number and Ack / Nack of symbols constituting the CBG, for example, the following values ​​14 symbols is a number of symbols of 1TTI used in LTE.

DESCRIPTION OF THE INVENTION

[0015]

　Hereinafter, the terminal device disclosed in the present application, the base station apparatus will be described in detail with reference to embodiments of a wireless communication system and a terminal device control method in the drawings. The terminal device disclosed in the present application by the following examples, the base station apparatus, does not wireless communication system and a terminal device control method is limited.
Example 1

[0016]

　Figure 1 is a block diagram of a terminal device. Terminal device 1 transmits and receives data by wireless communication with the base station apparatus 2 that will be described later. In this embodiment, the terminal apparatus 1 and the base station apparatus 2, using CBG (Code Block Group) type of feedback scheme as HARQ feedback scheme. Here it will be described below CBG type of the feedback type.

[0017]

　Figure 2 is a diagram for explaining CBG type of the feedback type. The terminal device 1, code block: the (CB Code Block) 101 was collected predetermined number CBG (Code Brock Group) 111 ~ transport block 115 containing 113 as the basic unit, receives data from the base station apparatus 2. In FIG. 2, although those collected two code blocks 101 and CBG111 ~ 113, not particularly limited to the number of code blocks of CBG111 ~ 113. In the following, when there is no need to distinguish between CBG111 ~ 113, expressed as "CBG110". The code block 101 is an example of a "first group". In addition, CBG110 corresponds to an example of the "second group".

[0018]

　Terminal 1 includes a radio unit 11, PDCCH (Physical Downlink Control Channel) receiving section 12 and the PDSCH (Physical Downlink Sheared Channel) reception processing unit 13. The terminal device 1 has a ACK (Acknowledgement) / NACK (Negative Acknowledgement) generator 14 and SR (Scheduling Request) generator 15. Furthermore, with a PUCCH (Physical Uplink Control Channel) generator 16 and PUSCH (Physical Uplink Sheared Channel) generator 17 and a buffer 18.

[0019]

　The radio unit 11 receives a signal of PDCCH and PDSCH including the control signals and data through the antenna from the base station apparatus 2. Here, the signal the radio unit 11 receives includes a transport block 115 that includes a plurality of CBG110 as shown in FIG. The radio unit 11 performs AD (Analog Digital) conversion on the received signal. Thereafter, the radio unit 11 outputs a signal of the received PDCCH and PDSCH to the PDCCH reception processing unit 12.

[0020]

　The radio unit 11 receives an input of the signal representing the ACK / NACK from the PUCCH generation section 16. The wireless unit 11 performs a DA (Digital Analog) conversion on the signal representing the ACK / NACK. Thereafter, the wireless unit 11 transmits a signal representing the ACK / NACK to the base station device 2 via the antenna.

[0021]

　The radio unit 11 receives an input signal containing data from the PUSCH generation unit 17. The wireless unit 11 performs a DA conversion on the signal including data. Thereafter, the wireless unit 11 transmits a signal including data via the antenna to the base station apparatus 2.

[0022]

　PDCCH receiving section 12 receives an input of PDCCH and PDSCH signal including control signals and data from the radio unit 11. Then, PDCCH receiving section 12 acquires a control signal by performing demodulation processing and decoding processing on PDCCH signals. The control signal also includes assignment information of radio resources. Then, PDCCH receiving section 12 outputs a signal of PDSCH to PDSCH reception processing unit 13 together with the control signal.

[0023]

　PDSCH reception processing unit 13 receives an input of the PDSCH signal from the PDCCH reception processing unit 12 together with the control signal. Then, PDSCH reception processing unit 13 acquires the data by performing demodulation processing and decoding processing on the PDCCH signal by using the MCS specified by the control signal (Modulation and Coding Scheme).

[0024]

　Then, PDSCH reception processing unit 13 identifies the CBG110 included in the data of one transport block 115. Then, PDSCH reception processing unit 13 determines whether or not the decoded data for each CBG110 contained in the transport block 115.

[0025]

　PDSCH reception processing unit 13, for CBG110 which data can be decoded, notifies the success of the decoding of the data to the ACK / NACK generation section 14. Also, PDSCH reception processing unit 13, for CBG110 failed to decode the data, and notifies the failure of decoding of the data to the ACK / NACK generation section 14. The PDSCH reception processing unit 13 is an example of "receiving portion".

[0026]

　ACK / NACK generation unit 14 is notified or failure notification of successful decoding of the data from the PDSCH reception processing unit 13 for each CBG110. Then, ACK / NACK generation unit 14 generates a Nack indicating the failure of the decoding of the Ack or data representative of the success of the decoding of the data for each CBG110. In the following, the information including one or both either Ack and Nack, referred to as "Ack / Nack".

[0027]

　Here, discussion will be made on generation of the Ack / Nack for each CBG110. Figure 3 is a diagram of an example of a bit pattern representing a mapped Ack / Nack to subcarriers. Here, the Ack / Nack will be explained for two CBG # 1 and # 2.

[0028]

　One resource block 121 and 122 includes 12 subcarriers. Each sub-carrier having a respective value. Ack / Nack is transmitted to the base station apparatus 2 by using a resource block 121 and 122. In Figure 3, it represents whether the value of the Ack / Nack for any of CBG # 1 or # 2 is in the respective sub-carrier.

[0029]

　Resource block 121 represents the case representing one at resource block 1 bit for CBG # 1 Ack or Nack, the mapping of the bit pattern of the Ack / Nack. In this case, it represents the value of the Ack or Nack for all subcarriers excluding the RS (Reference Signal) in the resource block 121 CBG # 1. That is, when the 1 a value representing the Nack and 0 values ​​representing the Ack, when returning an Ack relative CBG # 1, the subcarriers included in the resource block 121, the value of all but RS 0 is stored that. If relative CBG # 1 returns the Nack, the subcarriers included in the resource block 121, the value of all but RS 1 is stored.

[0030]

　In this case, since the value of the Ack or Nack one CBG for one resource block is stored, ACK / NACK generation unit 14 is an 8-bit bit by arranging the same value for resource blocks 121 generating a sequence as CBG # 1 of Ack / Nack. In this case, the base station apparatus 2, from one resource blocks 121 of the received signal, acquires the CBG # 1 of Ack / Nack.

[0031]

　On the other hand, resource blocks 122 represents the case representing one in the resource block CBG # 1 and # 2 of Ack or Nack of 1 bit for each, the mapping of the bit pattern of the Ack / Nack. In this case, each sub-carrier, except the RS resource block 122, a value representing the Ack or Nack for value or CBG # 2 represents an Ack or Nack for CBG # 1 is stored. For example, as shown in resource block 122, a value representing the Ack / Nack for the values ​​and CBG # 2 representing the Ack / Nack for CBG # 1 are arranged alternately in the sub-carriers other than RS. In this case, Ack / Nack is represented for each of the two CBG # 1 and # 2 in the two resource blocks.

[0032]

　In this case, ACK / NACK generation section 14, equal to 1 a value representing the Nack and 0 values ​​representing the Ack, the two resource blocks in the bit sequence representing the CBG # 1 and # 2 of the Ack / Nack, FIG generated as shown in 4. Figure 4 is a diagram showing an example of a value representing the Ack / Nack for two CBG mapped to two resource blocks.

[0033]

　For example, in Ack reception response CBG # 1, when receiving the response of CBG # 2 is Nack, ACK / NACK generation unit 14 generates a bit sequence of "01010101,01010101". In this case, the base station apparatus 2, such as by adding two information resource blocks 122 of the received signal to obtain an Ack / Nack for each of CBG # 1 and # 2.

[0034]

　If the number of received responses CBG110 represented by one resource blocks is increased, ACK / NACK generation unit 14 increases the pattern sequence of bits represented by 0 and 1. Thus, ACK / NACK generation section 14 may generate an Ack / Nack to represent information of Ack / Nack in one resource block 121 for one CBG110. Also, ACK / NACK generation section 14 may generate an Ack / Nack to represent information of Ack / Nack in a plurality of resource blocks 121 for a plurality of CBG110.

[0035]

　It is also possible to map multiple CBG of Ack / Nack to one subcarrier. Referring to FIG. 5, the mapping is an example for explaining the Ack / Nack of the plurality of CBG in one subcarrier. Figure 5 is a diagram showing an example in which two CBG of Ack / Nack has been mapped to a single one subcarrier resource block. The information of one sub-carrier in FIG. 5, for example, a sub-carrier quadrature phase shift keying: a (QPSK Quadrature Phase Shift Keying) 2-bit information in the case of modulation by.

[0036]

　For example, resource blocks 123 in FIG. 5 represent the mapping of the bit pattern of the Ack / Nack for sending an Ack / Nack for two CBG in one resource block. In this case, the subcarrier resource block 123 is a 2 bit. Then, representative values ​​of Ack or Nack for all subcarriers excluding the RS resource blocks 123 CBG # 1 and # 2. In this case, each sub-carrier is modulated with QPSK. Here, for example, equal to 1 a value representing the Nack and 0 values ​​representing the Ack, if returns the Ack relative to CBG # 1, returns the Nack against CBG # 2, sub-carriers included in the resource block 123 the value of all but RS (0, 1) is stored.

[0037]

　In this case, since the Ack or value of Nack two CBG for one resource block is stored, ACK / NACK generation section 14, with respect to the resource block 123, bits 16 bits obtained by arranging the same value sequence is generated as the Ack / Nack CBG # 1 and # 2. In this case, the base station apparatus 2, from one resource blocks 123 of the received signal, acquires the Ack / Nack CBG # 1 and # 2.

[0038]

　The resource block 124 in FIG. 5 represent the mapping of the bit pattern of the Ack / Nack for sending an Ack / Nack for four CBG in one resource block. Again, the sub-carrier of the resource block 123 is a 2 bit. To each sub-carrier, except the RS resource block 124, a value representing the Ack or Nack for value or CBG # 3 and # 4 representing the Ack or Nack for CBG # 1 and # 2 are stored. Again, the subcarriers are modulated by QPSK. For example, as shown in resource block 124, a value representing the Ack / Nack for the values ​​and CBG # 3 and # 4 representing the Ack / Nack for CBG # 1 and # 2 are arranged alternately in the sub-carriers other than RS . In this case, Ack / Nack is represented for each of the four CBG # 1 ~ # 4 in one resource block.

[0039]

　In this case, since the Ack or value of Nack four CBG for one resource block is stored, ACK / NACK generation section 14, with respect to the resource block 124, bits 32 bits arranged the same value sequence is generated as Ack / Nack of CBG # 1 ~ # 4. In this case, the base station apparatus 2, from one resource blocks 123 of the received signal, acquires the Ack / Nack of CBG # 1 ~ # 4.

[0040]

　The resource block group 125 in FIG. 5 represent the mapping of the bit pattern of the Ack / Nack for sending an Ack / Nack for four CBG in two resource blocks. Again, the subcarrier resource blocks 125, is a 2-bit. To each sub-carrier, except the RS resource block 125, a value representing the Ack or Nack for value or CBG # 3 and # 4 representing the Ack or Nack for CBG # 1 and # 2 are stored. Again, the subcarriers are modulated by QPSK. For example, as shown in the resource block group 125, a value representing the Ack / Nack for the values ​​and CBG # 3 and # 4 representing the Ack / Nack for CBG # 1 and # 2 are arranged alternately in the sub-carriers other than RS that. In this case, Ack / Nack is represented for each of the four CBG # 1 ~ # 4 in two resource blocks.

[0041]

　In this case, since the Ack or value of Nack four CBG for one resource block is stored, ACK / NACK generation section 14, with respect to the resource block group 125, 32 bits of which are arranged the same value bit sequence is generated as Ack / Nack of CBG # 1 ~ # 4. In this case, the base station device 2, the two resource blocks 123 of the received signal, acquires the Ack / Nack of CBG # 1 ~ # 4.

[0042]

　Then, ACK / NACK generation section 14 outputs the PUCCH generation section 16 as a reception response collectively Ack and Nack for a transport block 115 for each CBG110. The ACK / NACK generation section 14 corresponds to an example of the "response signal generation unit".

[0043]

　Buffer 18 has a first buffer 181 and second buffer 182. The first buffer 181 and second buffer 182 the data of the logical channels that are divided according to requirements or QoS, such as delay and reliability (Quality of Service) are stored, respectively. The first buffer 181 is a buffer for storing the transmission data in the high priority processing with little delay, such URLLC (Ultra-Reliable and Low Latency Communication). The second buffer 182 is a buffer for storing the transmission data in eMBB (Enhanced Mobile Brad Band) and lower processing priority, such as Web browsing. The first buffer 181 and second buffer 182, the transmission data generated processing like a CPU (Central Processing Unit) to execute is stored by the CPU.

[0044]

　SR generator 15 transmits data to the first buffer 181 or the second buffer 182 to check whether it has been stored. If the transmission data to the first buffer 181 or the second buffer 182 is stored, SR generator 15 generates a radio resource allocation request for requesting allocation of a radio resource for transmitting the transmission data.

[0045]

　Then, SR generation unit 15 outputs the PUCCH generation section 16 together with the information of the first buffer 181 or the second buffer 182 the radio resource allocation request is stored original transmission data. The SR generator 15 is an example of "a radio resource allocation request generator."

[0046]

　PUCCH generation unit 16 receives an input of information of the received responses to a single transport block 115 that summarizes the respective CBG110 of ACK and NACK from ACK / NACK generation section 14. Moreover, PUCCH generation unit 16 receives an input of the radio resource allocation request from the SR generator 15. Referring now to FIG. 6, described previously allocated radio resources for acknowledgment and radio resource allocation request. Figure 6 is a diagram illustrating allocation of radio resources. Vertical direction in FIG. 6 represents frequency, the horizontal direction represents time.

[0047]

　6, section sandwiched between PDCCH202 is the TTI (Transmission Time Interval) 201. Then, PDSCH203 is transmitted and received after the PDCCH202. Then, the radio resource 210 is a pre-allocated resources to the radio resource allocation request. Also, the radio resource 220 is a pre-allocated resources to the reception response. In the present embodiment, the PUCCH for transmitting a reception response, the signal at 2 symbol units is described in the case to be transmitted, the transmission unit in the PUCCH may use other units. For example, the PUCCH, the signal may be transmitted in one symbol unit. Hereinafter, the pre-allocated radio resource in the received response and the radio resource allocation request shown in FIG. 6, referred to as "normal radio resources."

[0048]

　PUCCH generation unit 16 determines whether to send simultaneously in TTI201 with a reception response or radio resource allocation request. Hereinafter, a case of transmitting a reception response and a radio resource allocation request in certain TTI201 at the same time, referred to as "simultaneous transmission". In other words, the simultaneous transmission is when the transmission of the reception response and the radio resource allocation request using a radio resource 210 and a radio resource 220 that overlaps in time direction in the terminal device 1 has occurred.

[0049]

　PUCCH generation unit 16, if not simultaneous transmission, the encoding and modulation processing on the data representing the data or radio resource allocation request indicating the a reception response Ack / Nack performed. Thereafter, PUCCH generation unit 16 assigns the usual radio resource to the data subjected to coding processing and modulation processing.

[0050]

　Figure 7 is a diagram showing the allocation of radio resources by the terminal apparatus according to the first embodiment. 7, the vertical direction in the assigned state 311-313 represents frequency and the horizontal direction represents time. For example, when sending a reception response without sending the radio resource allocation request, PUCCH generation unit 16 allocates the radio resources as shown in allocation state 311 of FIG. That, PUCCH generation unit 16 allocates the radio resources 220 resource blocks 301-303 to receive the response. In this case, radio resources 210 Resource block 300 is not assigned. Conversely, when sending a radio resource allocation request without sending a reception response, PUCCH generation unit 16 allocates the radio resources 210 in the resource block 300.

[0051]

　Then, PUCCH generation unit 16, the data representing the data or radio resource allocation request indicating the Ack / Nack arranged on PUCCH to generate a signal in response to allocation of radio resources. Thereafter, PUCCH generation unit 16 transmits the signal generated via the radio unit 11 to the base station apparatus 2. In this case, PUCCH generation unit 16 transmits the radio resource allocation request to the base station apparatus 2 by using the radio resource 210. Moreover, PUCCH generation unit 16 transmits the received response to the base station apparatus 2 by using the radio resource 220.

[0052]

　Next, a description is given of processing by the PUCCH generation section 16 in the case of simultaneous transmission. Here, the reception response and a radio resource allocation request occurs during simultaneous transmission, the state allocated similarly to the normal radio resources and if not simultaneous transmission of "normal allocation state".

[0053]

　For simultaneous transmission, PUCCH generation unit 16 allocates the radio resources as shown in allocation state 312 of FIG. Specifically, PUCCH generation unit 16 stores the information of the resource blocks allocated to the reception response time of simultaneous transmission in advance. That, PUCCH generation unit 16 stores in advance one excluded resource blocks from a resource block included in the normal radio resources received response. Then, PUCCH generation unit 16, the data representing the Ack / Nack to exclude resource blocks are allocated in a normal allocation state allocates radio resources 210 allocated to the radio resource allocation request would normally assigned state.

[0054]

　Then, the data representing the Ack / Nack other than the data allocated radio resources 210 allocates the resource blocks other than the excluded resource blocks of radio resources 220 as usual allocation status. For example, as shown in allocation state 312, PUCCH generation unit 16 allocates the resource blocks 301 and 303 in wireless resource 220 to the data representing the Ack / Nack other than the data allocated radio resources 210. In this case, PUCCH generation unit 16, the resource block 302 is not used.

[0055]

　By thus performing the assignment of radio resources, PUCCH generation unit 16 typically notifies the occurrence of the SR to the base station apparatus 2 by including an unused resource blocks not send Ack / Nack in the radio resources .

[0056]

　Here, whether the unused one of the resource blocks 301-303 can be determined freely. However, those who unused resource blocks is sandwiched resource blocks in use, the base station apparatus 2 easily detects that it is not used. Therefore, PUCCH generation unit 16, as in the assignment state 312, it is preferable to select an unused resource blocks as unused resource blocks is sandwiched resource blocks in use.

[0057]

　The contents of the signals to be mapped to the radio resources 210, the content of the signal to be mapped in the normal allocation status for this unused resource blocks may be directly applied. Alternatively, arranging the use resource blocks in the used resource blocks and radio resources 210 in the radio resource 220 in order of frequency, subjected to mapping the same manner as the transmission of the Ack / Nack of the normal allocation state, that is, low order or high frequency it may be.

[0058]

　Moreover, PUCCH generation unit 16 determines the radio resource allocation request to be transmitted, the radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182. Here, PUCCH generation unit 16, different from each other between the transmission of the transmission data in the transmission and high priority processing stored in the second buffer 182 of the transmission data in has been high priority processing stored in the first buffer 181 having a parameter for adjusting the transmission power density.

[0059]

　In this embodiment, PUCCH generation unit 16 as the parameter when the transmission of the transmission data stored in the first buffer 181, with parameters to increase the transmission power density. Moreover, PUCCH generation unit 16, as a parameter when the transmission of the transmission data stored in the second buffer 182, the parameters transmission power density becomes lower than that of the transmission of the transmission data stored in the first buffer 181 a. Parameters are, for example, the offset for the transmission power density in the case of transmitting a reception response. The value of this parameter, for example, is designated by RRC (Radio Resource Control) signal or PDCCH when notifying the resource settings of PUCCH from the base station apparatus 2.

[0060]

　PUCCH generation unit 16, if the radio resource allocation request for transmitting the transmission data stored in the first buffer 181, to increase the transmission power density of the allocated radio resources to the reception response as assignment state 312 . In contrast, if the radio resource allocation request for transmitting data in a low-priority process which is stored in the second buffer 182, PUCCH generation unit 16, typically a transmission power density of the received response as assignment state 312 same as the time of transmission of the reception response.

[0061]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 notifies the occurrence of the radio resource allocation request to the base station apparatus 2 together with the information of each CBG110 of Ack / Nack.

[0062]

　In the present embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16 is always such as the assignment state 313, the normal allocation state radio the allocation of resources may be performed. In this case, PUCCH generation unit 16 uses all resource blocks 300-301.

[0063]

　Thus, in this embodiment, the case of simultaneous reception, usually allocated resource amount of radio resources of the radio resource allocation request in comparison with the normal allocation status will no longer be used. In other words, the number of unused wireless resources does not increase so much. Here, if the low priority radio resource allocation request, since it is transmitted in Ack / Nack equivalent reliability, the transmission power can cover sufficiently. In contrast, if the high priority radio resource allocation request, certain transmission is desirable at high transmission power density in order to enhance reliability, also possible that insufficient transmission power is generated. The PUCCH generation unit 16 corresponds to an example of the "transmitting portion".

[0064]

　Returning to FIG. 1. PUSCH generation unit 17 obtains the information of the radio resource for transmitting the transmission data designated in response to a radio resource allocation request from the PDCCH reception processing unit 12. Next, PUSCH generation unit 17 obtains the transmission data corresponding to the transmitted radio resource allocation request from the first buffer 181 or the second buffer 182 of the buffer 18.

[0065]

　Then, PUSCH generation unit 17 performs encoding processing and modulation processing to the transmission data obtained. Next, PUSCH generation unit 17 allocates the radio resources specified in the transmission data subjected to coding processing and modulation processing. Thereafter, PUSCH generation unit 17 generates a signal to place the transmission data in accordance with the assignment of radio resources to the PUSCH. Thereafter, PUSCH generation unit 17 transmits the signal generated via the radio unit 11 to the base station apparatus 2.

[0066]

　Next, with reference to FIG. 8, it will be described the base station apparatus 2. Figure 8 is a block diagram of a base station apparatus. The base station apparatus 2, as shown in FIG. 8, with a PUCCH resource management unit 21, a buffer 22, a scheduler 23, a downlink signal baseband processing unit 24, an uplink signal baseband processing unit 25 and the radio unit 26. Buffer 22 is a temporary storage area of ​​the transmission data from the base station apparatus 2 acquires.

[0067]

　PUCCH resource management unit 21 notifies the resource configuration information resource configuration information and Ack / Nack for radio resource allocation request to the scheduler 23. Here, PUCCH resource management unit 21 may be periodically set at a predetermined cycle a normal radio resources of reception response transmitting radio resource allocation request and Ack / Nack. Additional, PUCCH resource management unit 21 may be set to determine the normal radio resources of reception response transmitting radio resource allocation request and Ack / Nack for each TTI.

[0068]

　The scheduler 23 identifies the data to be transmitted from the transmission data stored in the buffer 22. Then, the scheduler 23 performs scheduling of transmission of data specified.

[0069]

　Then, the scheduler 23 divides the data of the transport block 115 to send to CBG110. Then, the scheduler 23, to determine the MCS to be used. For example, the scheduler 23, for the data for URLLC, selects the MCS to increase the redundancy in comparison with the data for EMBB. The scheduler 23 generates control information for transmitting and receiving data. Furthermore, the scheduler 23 determines the wireless resources for transmitting data and control information. Then, the scheduler 23 outputs the CBG110 information in the transport block 115 of the data to be transmitted, MCS information, the generated control information and information of the wireless resources to be used for the downlink signal baseband processing unit 24.

[0070]

　Then, the scheduler 23 receives from the uplink signal baseband processing unit 25 inputs one bit of ACK or NACK for each CBG110. The scheduler 23 receives an input of the radio resource allocation request from the uplink signal baseband processing unit 25.

[0071]

　The scheduler 23 identifies a CBG110 which has received the NACK among the CBG110 included in the transport block 115 that sent. Then, the scheduler 23 determines the data to be retransmitted.

[0072]

　The scheduler 23 generates control information. Further, when receiving the radio resource allocation request, the scheduler 23 determines the normal radio resources used for transmitting data. The scheduler 23 determines the wireless resources to be used for data retransmission. Then, the scheduler 23, the information of the data to be retransmitted, MCS information, and outputs the generated control information and information of the wireless resources to be used for the downlink signal baseband processing unit 24. The scheduler 23 repeats the retransmission until it receives an ACK for all CBG110.

[0073]

　Downlink signal baseband processing unit 24 receives information of the data to be transmitted or retransmitted, MCS information, the input information of the control information and used radio resources from the scheduler 23. Next, downlink signal baseband processing unit 24 obtains the data corresponding to the information of the data to be transmitted or retransmitted received from the buffer 22. Next, downlink signal baseband processing unit 24, coding processing performed on received obtained using the coding rate specified by the information of the MCS data and control information. Further, downlink signal baseband processing unit 24 performs a modulation process on the obtained data and control information using a modulation scheme specified by the MCS information received. Then, the downlink signal baseband processing unit 24 assigns the control information and data to the specified radio resource, and place the control information to PDCCH, place the data in the PDSCH. The downlink signal baseband processing unit 24 outputs the control information and data to the wireless unit 26.

[0074]

　Radio unit 26 receives an input of control information and data from the downlink signal baseband processing unit 24. The wireless unit 26 performs a DA (Digital to Analog) conversion on the control information and data. Thereafter, the radio unit 26, a control signal and data by using the allocated radio resource via the antenna transmits to the terminal apparatus 1.

[0075]

　The radio unit 26 receives a signal including one or both either received response or radio resource allocation request for transmission data through the antenna from the terminal apparatus 1. The radio unit 26 performs AD (Analog to Digital) conversion on the received signal. Thereafter, the radio unit 26 outputs a signal including one or both either received response or radio resource allocation request for transmission data to the upstream signal baseband processing unit 25. The radio section 26 corresponds to an example of a "base station receiver."

[0076]

　Upstream signal baseband processing unit 25 performs demodulation processing and decoding processing to the signal including one or both either received response or radio resource allocation request for transmission data. Then, the uplink signal baseband processing unit 25 determines whether or not contain all information Ack / Nack resource blocks of radio resources 220 in the received signal. If the received signal contains information of all the Ack / Nack resource blocks of radio resources 220, i.e. does not contain unused resource block, the uplink signal baseband processing unit 25, determined not to be simultaneous transmission to.

[0077]

　If simultaneous transmission, the uplink signal baseband processing unit 25 obtains information of Ack / Nack from the normal radio resource 220 is a radio resource of acknowledgment for each CBG110.

[0078]

　In contrast, when included unused resource block, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. Here, the uplink signal baseband processing unit 25 stores in advance resource blocks used for the transmission of the reception response during simultaneous transmission shown in assigned state 312 in FIG. Then, the uplink signal baseband processing unit 25 obtains information of Ack / Nack from a predetermined resource block for each CBG110.

[0079]

　Also, if it does not contain all the information of Ack / Nack resource blocks of radio resources 220, the uplink signal baseband processing unit 25 determines whether or not the radio resource allocation request to the resource 210 is disposed. If the radio resource allocation request is arranged to the radio resource 210, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. In contrast, when the radio resource allocation request is not located in the radio resource 210, the uplink signal baseband processing unit 25 determines that none of the received response and the radio resource allocation request has not been received.

[0080]

　Thereafter, the upstream signal baseband processing unit 25 outputs information of Ack / Nack for each CBG110 to the scheduler 23. Further, when the radio resource allocation request is determined to have occurred, the uplink signal baseband processing unit 25 notifies the occurrence of the radio resource allocation request to the scheduler 23. The upstream signal baseband processing unit 25 is an example of "acquisition unit".

[0081]

　Next, with reference to FIG. 9, description will be given of a flow of transmission of the received response and the radio resource allocation request by the terminal apparatus 1. Figure 9 is a flowchart of transmission of the received response and the radio resource allocation request by a terminal apparatus according to the first embodiment. Here, a case that receives the radio signal from the base station apparatus 2 as an example.

[0082]

　PDSCH reception processing unit 13, via the radio unit 11 and the PDCCH reception processing unit 12 receives signals transmitted from the base station apparatus 2 (step S101).

[0083]

　ACK / NACK generation section 14, in the reception of signals by PDCCH reception processing unit 12, acquires the success or failure of the signal received for each CBG110. Then, ACK / NACK generating unit 14, depending on the success or failure of the signal received for each CBG110 acquired, it generates the reception response that includes the Ack / Nack for each CBG110 (step S102). Then, ACK / NACK generation section 14 outputs the generated reception response to the PUCCH generation section 16.

[0084]

　PUCCH generation unit 16 receives an input of the reception response that includes Ack / Nack for each CBG110 from ACK / NACK generation section 14. Moreover, PUCCH generation unit 16, depending on whether or not to acquire the radio resource allocation request from the SR generator 15 determines whether there is a radio resource allocation request (step S103).

[0085]

　If there is a radio resource allocation request (step S103: Yes), PUCCH generation unit 16 performs encoding and modulation processing on the acquired reception response. Then, PUCCH generation unit 16 allocates a portion of the radio resources of the radio resources and reception response of the encoding process and modulation process the normal radio resource allocation request allocation state in the received response subjected (step S104).

[0086]

　In contrast, when the radio resource allocation request is not (Step S103: No), subjecting the obtained modulation and coding processing on the received responses, it allocates all the usual radio resource to receive the response (step S105).

[0087]

　Thereafter, PUCCH generation unit 16 arranges the signal modulation processing and coding processing to the PUCCH has been performed in accordance with the assignment of radio resources (step S106). Then, PUCCH generation unit 16 outputs a signal modulation processing and encoding processing is applied to the radio unit 11.

[0088]

　The radio unit 11 receives an input of the signal modulation processing and encoding processing is applied from the PUCCH generation section 16. The radio unit 11 via the antenna performs DA conversion and transmits toward terminal apparatus 1 for modulation and coding processing is applied signal (step S107).

[0089]

　In the present embodiment described the case of simultaneous transmission of radio resource allocation request and reception response, to reduce the force on the transmission in the same manner even if the overlap with the radio resource allocation request and other signals be able to. For example, even when simultaneously transmitting a radio resource allocation request and CSI (Channel State Information) feedback, by the method described above can be reduced transmit power. Specifically, PUCCH generation unit 16, by performing similarly to the allocation of radio resources for received responses as described above the allocation of radio resources to CSI feedback, the radio resource allocation request without sending a radio resource allocation request it is possible to notify the occurrence to the base station. This makes it possible to reduce the transmission power.

[0090]

　As described above, the terminal apparatus according to the present embodiment, the case of simultaneous transmission, and transmits the received response using a part of the radio resource and receiving the response radio resource of the radio resource allocation request of the normal allocation status. Thus, the terminal device according to the present embodiment notifies the occurrence of the Ack / Nack and the radio resource allocation request of the CBG to the base station apparatus. Therefore, the terminal device, it is possible to reduce the transmission power in the case of simultaneous transmission. That is, the terminal apparatus according to this embodiment can transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently. In particular, in the case of insufficient transmission power of both of the radio resource allocation request and reception response while attempting to send a normal allocation state in the case of simultaneous transmission, the radio resource allocation request and sends the received response in the upper limit of transmission power You can be notified of the occurrence.
Example 2

[0091]

　Next, a second embodiment will be described. Terminal device according to the present embodiment transmits a part of the Ack / Nack sent in the case of Example 1 at the time of simultaneous transmission, to notify the rest of the Ack / Nack by the arrangement of the transmitted Ack / Nack There different from the first embodiment. Terminal device according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0092]

　PUCCH generation unit 16 receives an input of information reception response from the ACK / NACK generation section 14. Moreover, PUCCH generation unit 16 receives an input of the radio resource allocation request from the SR generator 15.

[0093]

　PUCCH generation unit 16 determines whether simultaneous transmission or. If not simultaneous transmission, PUCCH generation unit 16 performs encoding processing and modulation processing on the data representative of the received response or radio resource allocation request. Thereafter, in the same manner as in Example 1, PUCCH generation unit 16 allocates the radio resources to the signal subjected to encoding processing and modulation processing.

[0094]

　Next, a description is given of processing by the PUCCH generation section 16 in the case of simultaneous transmission. Figure 10 is a diagram illustrating allocation of radio resources by the terminal apparatus according to the second embodiment. In Figure 10, the vertical direction in the allocation status 314 represents frequency and the horizontal direction represents time. For simultaneous transmission, PUCCH generation unit 16 allocates the radio resources as shown in assignment state 314.

[0095]

　Specifically, PUCCH generation unit 16 stores in advance CBG110 which data representing the corresponding Ack / Nack directly sent. Figure 11 is a diagram showing an example of Ack / Nack for each CBG. Here, as shown in FIG. 11, there is CBG # 1 ~ # 6, PUCCH generation unit 16 stores in advance as a direct notification CBG401 for transmitting data representative of the CBG # 1 ~ # 4 directly Ack / Nack . In this case, PUCCH generation unit 16, CBG # 1 ~ # 4 of arrangement of Ack / Nack information, i.e. unused CBG indirect notification CBG402 performing status notification Ack / Nack by the resource blocks # 5 and # 6 stores in advance as.

[0096]

　Moreover, PUCCH generation unit 16 has previously unused resource table 410 as shown in FIG. 12. Figure 12 is a diagram showing an example of unused resource table. Unused resource table 410 represents an unused resource blocks corresponding to Ack / Nack indirect notification CBG.

[0097]

　PUCCH generation unit 16 obtains the received response and the resource block is divided representing information Ack / Nack resource blocks and indirect notification CBG402 representing the Ack / Nack direct notification CBG401 from ACK / NACK generation section 14. PUCCH generation unit 16 acquires information of each Ack / Nack of CBG # 5 ~ # 6 is an indirect notification CBG402 among the acquired reception response. Then, PUCCH generation unit 16 obtains the combination of unused resource blocks corresponding to each of the Ack / Nack of CBG # 5 ~ # 6 from the unused resource table 410. For example, as shown in FIG. 11, when returning an Ack for any CBG # 5 and # 6, PUCCH generation unit 16 obtains the resource blocks 301 and 302 as an unused resource blocks.

[0098]

　Next, PUCCH generation unit 16, CBG # a reception response representing a 1 ~ # 4 of Ack / Nack, the radio resource 210 and unused resource blocks other than the resource blocks allocated would normally assigned state to the radio resource allocation request assign a. For example, CBG # 5 and when returning an Ack for any # 6, PUCCH generation unit 16, a reception response to the CBG # 1 ~ # 4, resource blocks 300 and radio resources 220 falls radio resources 210 assign 301. That, PUCCH generation unit 16, a reception response to the CBG # 1 ~ # 4, allocates the radio resource as assigned state 314. In this case, PUCCH generation unit 16, resource blocks 302 and 303 are not used.

[0099]

　By thus performing the assignment of radio resources, PUCCH generation unit 16 typically notifies the occurrence of the SR to the base station apparatus 2 by including an unused resource blocks not send Ack / Nack in the radio resources . Moreover, PUCCH generation unit 16 reduces the signal to be transmitted.

[0100]

　Moreover, PUCCH generation unit 16 determines the radio resource allocation request to be transmitted, the radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182. Then, PUCCH generation unit 16, if the radio resource allocation request for transmitting the transmission data stored in the first buffer 181, the transmission power density of the allocated radio resources to the reception response as assignment state 312 higher. That is, for this, if the radio resource allocation request for transmission data of a low priority processing that is stored in the second buffer 182, PUCCH generation unit 16, the radio resource of the receiving response as assignment state 312 to equalize the transmission power density and the time of transmission of a normal reception response.

[0101]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 notifies the occurrence of the radio resource allocation request to the base station apparatus 2 together with the information of each CBG110 of Ack / Nack.

[0102]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0103]

　In this case, ACK / NACK generation unit 14 grasped in advance whether the indirect notification CBG402 one is a direct notification CBG401 of CBG110. Then, ACK / NACK generation unit 14 generates a reception response representing the Ack / Nack of direct notification CBG401. Also, ACK / NACK generation unit 14 generates a reception response representing information Ack / Nack indirect notification CBG402. Then, ACK / NACK generation section 14 outputs the generated reception response to the PUCCH generation section 16.

[0104]

　The base station apparatus 2 according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0105]

　Upstream signal baseband processing unit 25, like the PUCCH generation section 16 of the terminal apparatus 1 has an unused resource table 410. Further, uplink signal baseband processing unit 25 has previously direct notification CBG401 and information indirect notification CBG402 in CBG110.

[0106]

　Upstream signal baseband processing unit 25 receives the signal terminal 1 is transmitted from the radio unit 26. Then, the uplink signal baseband processing unit 25 performs a decoding process and demodulation process on the received signal. Then, the uplink signal baseband processing unit 25 determines whether or not contain all information Ack / Nack resource blocks of radio resources 220 in the received signal. If the received signal contains information of all the Ack / Nack resource blocks of radio resources 220, i.e. does not contain unused resource block, the uplink signal baseband processing unit 25, determined not to be simultaneous transmission to.

[0107]

　If simultaneous transmission, the uplink signal baseband processing unit 25 obtains information of Ack / Nack from the normal radio resource 220 is a radio resource of acknowledgment for each CBG110.

[0108]

　In contrast, when included unused resource block, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. Then, uplink signal baseband processing unit 25 directly notifies CBG401 identifies a placement resource blocks in the normal radio resource 220 is a radio resource of acknowledgment. Then, the uplink signal baseband processing unit 25 obtains information of Ack / Nack for direct notification CBG401. Further, uplink signal baseband processing unit 25 uses the unused resource table 410, determines Ack / Nack of indirect notification CBG402 from the arrangement of the unused resource blocks in a wireless resource 220.

[0109]

　Also, if it contains no information Ack / Nack resource blocks in any of the radio resources 220, the uplink signal baseband processing unit 25, determines whether radio resource allocation request to the radio resource 210 is disposed to. If the radio resource allocation request is arranged to the radio resource 210, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. In contrast, when the radio resource allocation request is not located in the radio resource 210, the uplink signal baseband processing unit 25 determines that none of the received response and the radio resource allocation request has not been received.

[0110]

　Thereafter, the upstream signal baseband processing unit 25 outputs information of Ack / Nack for each CBG110 to the scheduler 23. Further, when the radio resource allocation request is determined to have occurred, the uplink signal baseband processing unit 25 notifies the occurrence of the radio resource allocation request to the scheduler 23.

[0111]

　Next, referring to FIG. 13, description will be given of a flow of transmission of the received response and the radio resource allocation request by the terminal apparatus 1 according to this embodiment. Figure 13 is a flowchart of transmission of the received response and the radio resource allocation request by a terminal apparatus according to the second embodiment. Here, a case that receives the radio signal from the base station apparatus 2 as an example.

[0112]

　PDSCH reception processing unit 13, via the radio unit 11 and the PDCCH reception processing unit 12 receives signals transmitted from the base station apparatus 2 (step S201).

[0113]

　ACK / NACK generation section 14, in the reception of signals by PDCCH reception processing unit 12, acquires the success or failure of the signal received for each CBG110. Then, ACK / NACK generating unit 14, depending on the success or failure of the signal received for each CBG110 acquired, it generates the reception response that includes the Ack / Nack for each CBG110 (step S202). For example, PDCCH reception processing unit 12 generates a reception response to the resource block is divided representing information Ack / Nack resource blocks and indirect notification CBG402 representing the Ack / Nack of direct notification CBG401. Then, ACK / NACK generation section 14 outputs the generated reception response to the PUCCH generation section 16.

[0114]

　PUCCH generation unit 16 receives an input of the reception response that includes Ack / Nack for each CBG110 from ACK / NACK generation section 14. Moreover, PUCCH generation unit 16, depending on whether or not to acquire the radio resource allocation request from the SR generator 15 determines whether there is a radio resource allocation request (step S203).

[0115]

　If there is a radio resource allocation request (step S203: Yes), PUCCH generation unit 16 uses an unused resource table 410, and acquires the information of the unused resource blocks representing the Ack / Nack indirect notification CBG402 (step S204 ).

[0116]

　PUCCH generation unit 16 directly notifies the CBG401 of Ack / Nack subjected to modulation processing and coding processing, assigns radio resources other than the unused resource block from a normal radio resources of the radio resource allocation request and reception response (step S205) .

[0117]

　In contrast, when there is a radio resource allocation request (step S203: negative), PUCCH generation unit 16 performs modulation processing and coding processing on the obtained reception response, it allocates all the usual radio resource to receive the response (step S206).

[0118]

　Thereafter, PUCCH generation unit 16 arranges the signal modulation processing and coding processing to the PDCCH is performed in accordance with the assignment of radio resources (step S207). Then, PUCCH generation unit 16 outputs a signal modulation processing and encoding processing is applied to the radio unit 11.

[0119]

　The radio unit 11 receives an input of the signal modulation processing and encoding processing is applied from the PUCCH generation section 16. The radio unit 11 via the antenna performs DA conversion and transmits toward terminal apparatus 1 for modulation and coding processing is applied signal (step S208).

[0120]

　As described above, the terminal apparatus according to this embodiment, Ack transmits a signal representing directly the Ack / Nack for direct notification CBG to the base station apparatus, for directly notifying CBG the Ack / Nack for indirect notification CBG / It is notified by the placement of the Nack. This makes it possible to transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently. Further, it is possible to further reduce the transmission power as compared with Example 1.
Example 3

[0121]

　Next, a third embodiment will be described. Terminal device according to the present embodiment generates the CBG groups by grouping CBG during simultaneous transmission, to notify the Ack / Nack for each CBG groups is different from example 1. Further, by increasing the CB number corresponding per-bit Ack / Nack for feedback during simultaneous transmission as compared with the case of not simultaneously transmitted in the present embodiment, reducing the number of bits of the Ack / Nack feedback. Terminal device according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0122]

　PUCCH generation unit 16 receives an input of information reception response from the ACK / NACK generation section 14. Moreover, PUCCH generation unit 16 receives an input of the radio resource allocation request from the SR generator 15.

[0123]

　PUCCH generation unit 16 determines whether simultaneous transmission or. If not simultaneous transmission, PUCCH generation unit 16 performs encoding processing and modulation processing on the data representative of the received response or radio resource allocation request. Thereafter, in the same manner as in Example 1, PUCCH generation unit 16 allocates the radio resources to the signal subjected to encoding processing and modulation processing.

[0124]

　Next, a description is given of processing by the PUCCH generation section 16 in the case of simultaneous transmission. Figure 14 is a diagram showing an example of CBG groups generated by PUCCH generation unit according to the third embodiment. Again, a description will be given of a case where CBG # 1 ~ # 6 is present. PUCCH generation unit 16 obtains the information of Ack / Nack to each CBG # 1 ~ # 6 from the received response retrieved from the ACK / NACK generation section 14.

[0125]

　Here, PUCCH generation unit 16 has a pre-CBG # of information how to group 1 to # 6 in advance. Then, PUCCH generation unit 16 in accordance with predetermined information, grouping CBG # 1 ~ # 6. For example, as shown in FIG. 14, PUCCH generation unit 16, CBG # 1 and # 2 generates CBG groups ## 1 and ## 2 by one as it is, CBG # 3 and # 4, and, CBG Conclusion # 5 and # 6 respectively generating the CBG group ## 3 and ## 4.

[0126]

　In this case, PUCCH generation unit 16, each of CBG groups ## 1 to ## 4 of the Ack / Nack, a logical sum of the Ack / Nack of CBG110 included in each group. That, PUCCH generation unit 16, and CBG # 1 and # intact CBG groups ## 1 and ## 2 the Ack / Nack for 2 Ack / Nack. Moreover, PUCCH generation unit 16, since the response to either CBG # 3 and # 4 is also at Ack, and Ack responses to CBG Group ## 3. Moreover, PUCCH generation unit 16 is Ack response to CBG # 5, the response to any of CBG # 6 since is Nack, and Nack responses to CBG Group ## 4.

[0127]

　Then, PUCCH generation unit 16, as shown in allocation state 315 in FIG. 15, the normal CBG groups a predetermined part of the resource blocks of the radio resources ## 1 to ## 4 of the reception response Ack / assigned to reception response representing a nack. Figure 15 is a diagram showing the allocation of radio resources by the terminal apparatus according to the third embodiment. Here, PUCCH generation unit 16 allocates resource blocks 302 and 301 of radio resources 220 in the reception response representing the Ack / Nack of CBG groups ## 1 to ## 4, the resource block 303 an unused resource blocks.

[0128]

　Thus, PUCCH generation unit 16, the normal base station apparatus 2 by including an unused resource blocks not send Ack / Nack in the radio resources and notifies the occurrence of the SR. Moreover, PUCCH generation unit 16 reduces the signal to be transmitted.

[0129]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted, changes the transmission power density by radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182.

[0130]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 notifies the occurrence of the radio resource allocation request to the base station apparatus 2 together with the information of each CBG110 of Ack / Nack.

[0131]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0132]

　The base station apparatus 2 according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0133]

　Upstream signal baseband processing unit 25, like the PUCCH generation section 16 of the terminal apparatus 1 has a CBG110 information included in each CBG groups ## 1 to ## 4 in advance. Further, uplink signal baseband processing unit 25 has previously position Ack / Nack is arranged for CBG groups ## 1 to ## 4.

[0134]

　Upstream signal baseband processing unit 25 receives the signal terminal 1 is transmitted from the radio unit 26. Then, the uplink signal baseband processing unit 25 performs a decoding process and demodulation process on the received signal. Then, the uplink signal baseband processing unit 25 determines whether or not contain all information Ack / Nack resource blocks of radio resources 220 in the received signal. If the received signal contains information of all the Ack / Nack resource blocks of radio resources 220, i.e. does not contain unused resource block, the uplink signal baseband processing unit 25, determined not to be simultaneous transmission to.

[0135]

　If simultaneous transmission, the uplink signal baseband processing unit 25 obtains information of Ack / Nack from the radio resource 220 is a normal radio resources received response for each CBG # 1 ~ # 6.

[0136]

　In contrast, when included unused resource block, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. Then, uplink signal baseband processing unit 25 obtains information of Ack / Nack for CBG groups ## 1 to ## 4 from a predetermined resource blocks in a wireless resource 220 is a normal radio resources received response. Then, the uplink signal baseband processing unit 25 from the information of Ack / Nack for CBG groups ## 1 to ## 4, to obtain the Ack / Nack for each CBG # 1 to # 6.

[0137]

　Also, if all of the resource blocks of a radio resource 220 does not contain information for Ack / Nack, the uplink signal baseband processing unit 25 determines whether or not the radio resource allocation request to the radio resource 210 is disposed . If the radio resource allocation request is arranged to the radio resource 210, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. In contrast, when the radio resource allocation request is not located in the radio resource 210, the uplink signal baseband processing unit 25 determines that none of the received response and the radio resource allocation request has not been received.

[0138]

　Thereafter, the upstream signal baseband processing unit 25 outputs information of Ack / Nack for each CBG110 to the scheduler 23. Further, when the radio resource allocation request is determined to have occurred, the uplink signal baseband processing unit 25 notifies the occurrence of the radio resource allocation request to the scheduler 23.

[0145]

　Then, PUCCH generation unit 16 performs modulation processing and coding processing to Ack / Nack for each CBG group, allocates a portion of the radio resources of the normal radio resources received response (step S306).

[0146]

　In contrast, when there is a radio resource allocation request (step S303: negative), PUCCH generation unit 16 performs modulation processing and coding processing on the obtained reception response, thus the reception response that includes the Ack / Nack of CBG assigning all the usual radio resource (step S307).

[0147]

　Thereafter, PUCCH generation unit 16 arranges the signal modulation processing and coding processing to the PUCCH has been performed in accordance with the assignment of radio resources (step S308). Then, PUCCH generation unit 16 outputs a signal modulation processing and encoding processing is applied to the radio unit 11.

[0148]

　The radio unit 11 receives an input of the signal modulation processing and encoding processing is applied from the PUCCH generation section 16. The radio unit 11 via the antenna performs DA conversion and transmits toward terminal apparatus 1 for modulation and coding processing is applied signal (step S309).

[0149]

　As described above, the terminal device according to the present embodiment notifies the base station apparatus Ack / Nack for CBG group summarizing CBG. This makes it possible to transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently.

Here, a description will be given of a case where CBG # 1 ~ # 8 exists. PUCCH generation unit 16 obtains the information of Ack / Nack to each CBG # 1 ~ # 8 from the received response retrieved from the ACK / NACK generation section 14.

[0152]

　Here, PUCCH generation unit 16 has a one of information how grouping of previously CBG # 1 ~ # 8 in advance. Then, PUCCH generation unit 16 in accordance with predetermined information, grouping CBG # 1 ~ # 8. For example, PUCCH generation unit 16 in FIG. 17, CBG # 1 and # 2, CBG # 3 and # 4, CBG # 5 and # 6, and, CBG groups ## 1 to collectively respectively CBG # 7 and # 8 ## to generate a 4.

[0156]

　By thus performing the assignment of radio resources, PUCCH generation unit 16 typically notifies the occurrence of the SR to the base station apparatus 2 by including an unused resource blocks not send Ack / Nack in the radio resources . Moreover, PUCCH generation unit 16 reduces the signal to be transmitted.

[0157]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted, changes the transmission power density by radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182.

[0158]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 notifies the occurrence of the radio resource allocation request to the base station apparatus 2 together with the information of each CBG110 of Ack / Nack.

[0159]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0160]

　The base station apparatus 2 according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0161]

　Upstream signal baseband processing unit 25, like the PUCCH generation section 16 of the terminal apparatus 1 has a CBG110 information included in each CBG groups ## 1 to ## 4 in advance. Further, uplink signal baseband processing unit 25 has a position where the Ack / Nack is arranged for directly notifying CBG group 403 in advance.

[0162]

　Upstream signal baseband processing unit 25 receives the signal terminal 1 is transmitted from the radio unit 26. Then, the uplink signal baseband processing unit 25 performs a decoding process and demodulation process on the received signal. Then, the uplink signal baseband processing unit 25, if it contains an unused resource blocks to the radio resources 220 in the received signal, the uplink signal baseband processing unit 25, to grasp the occurrence of the radio resource allocation request. Then, uplink signal baseband processing unit 25 obtains information of Ack / Nack for direct notification CBG group 403 from a predetermined resource blocks in a wireless resource 220 is a normal radio resources received response.

Example 5

[0164]

　Next, a description will be given of an embodiment 5. Terminal device according to this embodiment, the radio resource allocation request during simultaneous transmissions as it is divided into direct notification CBG and indirect notification CBG the CBG, Ack / Nack indirect notification CBG at the location of the Ack / Nack for direct notification CBG to notify. Terminal device according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0165]

　Figure 20 is a diagram illustrating allocation of radio resources by the terminal apparatus according to the fifth embodiment. Allocation state 321-323 in FIG. 20 represents time in lateral direction represents frequency, respectively in the longitudinal direction.

[0166]

　In this embodiment, PUCCH generation unit 16, when sending the received response when not simultaneous transmission, as shown in allocation state 321, allocate all the usual radio resource to receive the response.

[0167]

　In contrast, in the case of simultaneous transmission, PUCCH generation unit 16 allocates the radio resource 210 is a normal radio resources of the radio resource allocation request in the allocation state 322 to the radio resource allocation request. Moreover, PUCCH generation unit 16 divides the direct notification CBG401 and indirect notification of CBG110 CBG402. Then, PUCCH generation unit 16 assigns the assignment state 322 to represent the Ack / Nack indirect notification CBG402 to Ack / Nack for notifying the portion of radio resources 220 directly CBG401.

[0168]

　Accordingly, PUCCH generation unit 16 allocates the resource blocks 301, 302 and 304 directly notifies CBG401 of Ack / Nack. In this case, PUCCH generation unit 16, by the resource block 303 an unused resource blocks, and notifies the Ack / Nack indirect notification CBG402.

[0169]

　Thus, PUCCH generation unit 16 typically reduces the signal to be transmitted by including the unused resource blocks not send Ack / Nack in the radio resources, to reduce the transmission power.

[0170]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted is, from the radio resource allocation request crab for transmission data stored in any of the first buffer 181 or the second buffer 182, transmission power density of the radio resources 210 to change the. Thereafter, PUCCH generation unit 16 transmits the data of the radio resource allocation request and reception response to the base station 2 via the radio unit 11 at the transmission power density was determined using the allocated radio resources.

[0171]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, as PUCCH generation unit 16, shown in assigned state 323, the normal allocation state it may be allocated radio resources.

[0172]

　The base station apparatus 2 according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0173]

　Upstream signal baseband processing unit 25 receives the signal terminal 1 is transmitted from the radio unit 26. Then, the uplink signal baseband processing unit 25 performs a decoding process and demodulation process on the received signal. Then, the uplink signal baseband processing unit 25 determines whether simultaneous transmission or from the received signal. If simultaneous transmission, the uplink signal baseband processing unit 25 obtains the radio resource allocation request or the CBG110 of Ack / Nack.

[0174]

　In contrast, in the case of simultaneous reception, firstly, the uplink signal baseband processing unit 25 obtains the radio resource allocation request. Then, uplink signal baseband processing unit 25 obtains information of Ack / Nack for notification directly from the radio resource 220 CBG401 in the received signal. Further, uplink signal baseband processing unit 25 obtains the Ack / Nack of indirect notification CBG402 from arrangement of direct notification CBG401.

[0175]

　Thereafter, the upstream signal baseband processing unit 25 outputs information of Ack / Nack for each CBG110 to the scheduler 23. Further, when the radio resource allocation request is determined to have occurred, the uplink signal baseband processing unit 25 notifies the occurrence of the radio resource allocation request to the scheduler 23.

[0176]

　As described above, the terminal apparatus according to this embodiment, the radio resource allocation request is transmitted using an ordinary radio resources, and transmits the received response using a direct notification CBG and indirect notification CBG. This makes it possible to transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently. Further, it is possible to reduce the transmission power.

[0177]

　In the above it has been described simultaneous transmission time reduction of the transmission power of the radio resource allocation request and reception response, even reducing the transmission power in the simultaneous transmission of other signals, using the method described above realizes can do. For example, the reception response, even if there is a low reception response priority of high priority reception response and EMBB friendly for URLLC, can Ru reduced transmission power by using the method described above.

[0178]

　For example, PUCCH generation unit 16, like the radio resource allocation request as described above, allocates the usual radio resource to receive the response for URLLC. Moreover, PUCCH generation unit 16, like the received response described above, transmits a reception response for EMBB using direct notification CBG401 and indirect notification CBG402. Accordingly, PUCCH generation unit 16 can reduce the number of bits used to receive response for EMBB, it is possible to reduce the transmission power. Moreover, PUCCH generation unit 16 can also distribute the reduced power to the reception response for URLLC, it is possible to improve the reliability of the reception response for URLLC.

[0179]

　Furthermore, it is possible to use the same method in a radio resource allocation request, simultaneous transmission of reception response and EMBB for receiving responses for URLLC. In this case, PUCCH generation unit 16, like the radio resource allocation request as described above, allocates the usual radio resource to receive the response radio resource allocation request and for URLLC. Moreover, PUCCH generation unit 16, like the received response described above, transmits a reception response for EMBB using direct notification CBG401 and indirect notification CBG402. Accordingly, PUCCH generation unit 16 can reduce the number of bits used to receive response for EMBB, it is possible to reduce the transmission power. Moreover, PUCCH generation unit 16 may also be distributed reduced electric power to the reception response of the wireless resource allocation request and URLLC friendly, they can improve their reliability.
Example 6

[0180]

　Next, Example 6 will be described. Terminal device according to this embodiment, the radio resource allocation request during simultaneous transmission in the same manner as in Example 5 transmits as it is. The terminal device according to this embodiment, groups the CBG, notifies Ack / Nack for each CBG group. Terminal device according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0181]

　The processing by the PUCCH generation section 16 in the case of the simultaneous transmission will be described. Figure 21 is a diagram showing an example of CBG groups generated by PUCCH generation unit according to the sixth embodiment. Here, a description will be given of a case where CBG # 1 ~ # 6 exists. PUCCH generation unit 16 obtains the information of Ack / Nack to each CBG # 1 ~ # 6 from the received response retrieved from the ACK / NACK generation section 14.

[0182]

　Here, PUCCH generation unit 16 has a pre-CBG # of information how to group 1 to # 6 in advance. Then, PUCCH generation unit 16 in accordance with predetermined information, grouping CBG # 1 ~ # 6. For example, as shown in FIG. 21, PUCCH generation unit 16 generates the CBG # 1 ~ # 3 and CBG # 4 ~ # CBG groups ## 1 and ## 2 6 collectively respectively.

[0183]

　In this case, PUCCH generation unit 16, each of CBG groups ## 1 to ## 2 of Ack / Nack, a logical sum of the Ack / Nack of CBG110 included in each group.

[0184]

　Then, PUCCH generation unit 16, as shown in allocation state 324 in FIG. 22, allocates radio resources 210 is generally radio resources of the radio resource allocation request to the radio resource allocation request. Moreover, PUCCH generation unit 16 assigns a predetermined part of the resource blocks of the normal radio resources received in response to the received response indicating the Ack / Nack CBG group ## 1 and ## 2. Figure 22 is a diagram showing the allocation of radio resources by the terminal apparatus according to the sixth embodiment. Here, PUCCH generation unit 16 allocates resource blocks 303 of radio resources 220 in the reception response representing the Ack / Nack of CBG groups ## 1 and ## 2, the resource blocks 301 and 302 and unused resource blocks.

[0185]

　Thus, PUCCH generation unit 16 typically reduces the signal to be transmitted by including the unused resource blocks not send Ack / Nack in the radio resources, to reduce the transmission power.

[0186]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted, changes the transmission power density by radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182.

[0187]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 transmits the generated radio resource allocation request to the base station apparatus 2 together with the information of each CBG110 of Ack / Nack.

[0188]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0189]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted is, from the radio resource allocation request crab for transmission data stored in any of the first buffer 181 or the second buffer 182, transmission power density of the radio resources 210 to change the. Thereafter, PUCCH generation unit 16 transmits the data of the radio resource allocation request and reception response to the base station 2 via the radio unit 11 at the transmission power density was determined using the allocated radio resources.

[0190]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0191]

　As described above, the terminal apparatus according to this embodiment, the radio resource allocation request is normally transmitted using a radio resource, it transmits a reception response using CBG groups. This makes it possible to transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently. Further, it is possible to reduce the transmission power.

[0192]

　In the above it has been described simultaneous transmission time reduction of the transmission power of the radio resource allocation request and reception response, even reducing the transmission power in the simultaneous transmission of likewise other signals as in Example 5, above it can be achieved using the method. For example, the reception response, even if there is a low reception response priority of high priority reception response and EMBB friendly for URLLC, can Ru reduced transmission power by using the method described above.

[0193]

　For example, PUCCH generation unit 16, like the radio resource allocation request as described above, allocates the usual radio resource to receive the response for URLLC. Moreover, PUCCH generation unit 16, like the received response described above, transmits a reception response for EMBB using CBG groups. Accordingly, PUCCH generation unit 16 can reduce the number of bits used to receive response for EMBB, it is possible to reduce the transmission power. Moreover, PUCCH generation unit 16 can also distribute the reduced power to the reception response for URLLC, it is possible to improve the reliability of the reception response for URLLC.

[0194]

　Furthermore, it is possible to use the same method in a radio resource allocation request, simultaneous transmission of reception response and EMBB for receiving responses for URLLC.
Example 7

[0195]

　Next, Example 7 will be described. Terminal device according to this embodiment, the radio resource allocation request during simultaneous transmission in the same manner as in Example 5 transmits as it is. The terminal device according to this embodiment, the containing more resource blocks information Nack among resource blocks to transmit a reception response to non transmission resource blocks. Terminal device according to the present embodiment is also represented in the block diagram of FIG. In the following description, it will not be described functions of the same respective parts as in Example 1.

[0196]

　The processing by the PUCCH generation section 16 in the case of the simultaneous transmission will be described. Figure 23 is a diagram for explaining the calculation of the number of Nack in each resource block. Here, a description will be given of a case where CBG # 1 ~ # 6 exists.

[0197]

　PUCCH generation unit 16, for example, obtains information of Ack / Nack for each of CBG # 1 ~ # 6 shown in Ack / Nack information 421 of FIG. 23. Next, PUCCH generation unit 16 identifies resource blocks 301-303 to be assigned in the normal allocation state to the CBG # 1 ~ # of Ack / Nack for 6 information. Here, as shown in Table 422, the resource block 301 is allocated to CBG # 1 and # 2. The resource block 302 is allocated to CBG # 3 and # 4. The resource block 303 is allocated to CBG # 5 and # 6.

[0198]

　Next, PUCCH generation unit 16 obtains the number of Nack of CBG # 1 ~ # 6 corresponding to the respective resource blocks 301-303. Here, the number of Nack in the resource block 301 is 2, the number of Nack in the resource block 302 is zero, the number of Nack in the resource block 303 is 1.

[0199]

　Then, PUCCH generation unit 16, an unused resource block having the largest resource blocks 301 in the number of Nack. Then, PUCCH generation unit 16 allocates the radio resources as shown in allocation state 325 of FIG. 24. Figure 24 is a diagram showing the allocation of radio resources by the terminal device according to a seventh embodiment.

[0200]

　Specifically, PUCCH generation unit 16 allocates the radio resource 210 is a normal radio resources of the radio resource allocation request to the radio resource allocation request. Moreover, PUCCH generation unit 16 performs as usual assignment and allocation status using resource blocks 302 and 303 other than the resource blocks 301 unused resource blocks.

[0201]

　Thus, PUCCH generation unit 16 typically reduces the signal to be transmitted by including the unused resource blocks not send Ack / Nack in the radio resources, to reduce the transmission power.

[0202]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted, changes the transmission power density by radio resource or allocation request for the transmission data stored in any of the first buffer 181 or the second buffer 182.

[0203]

　Thereafter, PUCCH generation unit 16 transmits data of the received response through the radio unit 11 at the transmission power density was determined using a radio resource allocated to the base station apparatus 2. Accordingly, PUCCH generation unit 16 transmits together with CBG # 1 and # each other than the information of the second Ack / Nack CBG # 3 ~ # 4 of Ack / Nack information of the radio resource allocation request to the base station apparatus 2.

[0204]

　If Nack is returned, the base station apparatus 2 retransmits the data Nack is returned. Moreover, even if no response is returned, the base station apparatus 2 retransmits the data does not return a response. That is, even without the terminal device 1 returns a Nack, since retransmission of data is performed by the base station apparatus 2, even without return Ack / Nack in the resource block including many Nack, and when it returns Ack / Nack it can be said that almost the same processing is performed. Therefore, PUCCH generation unit 16 in the present embodiment is directed to an unused resource blocks of resource blocks including many Nack.

[0205]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0206]

　Moreover, PUCCH generation unit 16, the radio resource allocation request to be transmitted is, from the radio resource allocation request crab for transmission data stored in any of the first buffer 181 or the second buffer 182, transmission power density of the radio resources 210 to change the. Thereafter, PUCCH generation unit 16 transmits the data of the radio resource allocation request and reception response to the base station 2 via the radio unit 11 at the transmission power density was determined using the allocated radio resources.

[0207]

　Here, also in this embodiment, even in the case of simultaneous transmission, if insufficient transmission power allocation of the normal allocation state, PUCCH generation unit 16, even if the allocation of radio resources of the normal allocation state good.

[0208]

　Next, referring to FIG. 25, description will be given of a flow of transmission of the received response and the radio resource allocation request by the terminal apparatus 1 according to this embodiment. Figure 25 is a flowchart of transmission of the received response and the radio resource allocation request by a terminal apparatus according to Embodiment 7. Here, a case that receives the radio signal from the base station apparatus 2 as an example.

[0209]

　PDSCH reception processing unit 13, via the radio unit 11 and the PDCCH reception processing unit 12 receives signals transmitted from the base station apparatus 2 (step S401).

[0210]

　ACK / NACK generation section 14, in the reception of signals by PDCCH reception processing unit 12, acquires the success or failure of the signal received for each CBG110. Then, ACK / NACK generating unit 14, depending on the success or failure of the signal received for each CBG110 acquired, it generates the reception response that includes the Ack / Nack for each CBG110 (step S402). Then, ACK / NACK generation section 14 outputs the generated reception response to the PUCCH generation section 16.

[0211]

　PUCCH generation unit 16 receives an input of the reception response that includes Ack / Nack for each CBG110 from ACK / NACK generation section 14. Moreover, PUCCH generation unit 16, depending on whether or not to acquire the radio resource allocation request from the SR generator 15 determines whether there is a radio resource allocation request (step S403).

[0212]

　If there is a radio resource allocation request (step S403: Yes), PUCCH generation unit 16 specifies the number of Nack included in each resource block 301-303 of radio resources 220 in the normal allocation state (step S404).

[0213]

　Moreover, PUCCH generation unit 16 determines the non-transmission resource blocks in the large number of the order of Nack (step S405).

[0214]

　Then, PUCCH generation unit 16 allocates an unused resource blanking other blocks of the resource blocks 302 and 303 in the received response excluding the Ack / Nack is not transmitted is allocated to the non-transmission block in the normal allocation state (step S406).

[0215]

　In contrast, when there is no radio resource allocation request (step S403: negative), PUCCH generation unit 16 performs modulation processing and coding processing on the obtained reception response, allocates all the usual radio resource on the generated reception response (step S407).

[0216]

　Thereafter, PUCCH generation unit 16 arranges the signal modulation processing and coding processing to the PUCCH has been performed in accordance with the assignment of radio resources (step S408). Then, PUCCH generation unit 16 outputs a signal modulation processing and encoding processing is applied to the radio unit 11.

[0217]

　The radio unit 11 receives an input of the signal modulation processing and encoding processing is applied from the PUCCH generation section 16. The radio unit 11 via the antenna performs DA conversion and transmits toward terminal apparatus 1 for modulation and coding processing is applied signal (step S409).

[0218]

　As described above, the terminal apparatus according to this embodiment, normally transmits a radio resource allocation request by using the radio resource transmits a reception response, as unused resource blocks of resource blocks including many Nack of the received response to. This makes it possible to transmit the information including the Ack / Nack feedback information and the radio resource allocation request such efficiently. Further, it is possible to reduce the transmission power.

[0219]

　In the above it has been described simultaneous transmission time reduction of the transmission power of the radio resource allocation request and reception response, even reducing the transmission power in the simultaneous transmission of likewise other signals as in Example 5, above it can be achieved using the method. For example, the reception response, even if there is a low reception response priority of high priority reception response and EMBB friendly for URLLC, can Ru reduced transmission power by using the method described above.

[0220]

　For example, PUCCH generation unit 16, like the radio resource allocation request as described above, allocates the usual radio resource to receive the response for URLLC. Moreover, PUCCH generation unit 16, like the received response described above, the non-transmission resource blocks more resource blocks of Nack of resource blocks allocated to the reception response for EMBB. Accordingly, PUCCH generation unit 16 can reduce the number of bits used to receive response for EMBB, it is possible to reduce the transmission power. Moreover, PUCCH generation unit 16 can also distribute the reduced power to the reception response for URLLC, it is possible to improve the reliability of the reception response for URLLC.

[0221]

　Furthermore, it is possible to use the same method in a radio resource allocation request, simultaneous transmission of reception response and EMBB for receiving responses for URLLC.
