BACKGROUND
[0002]
　In 3GPP (3rd Generation Partnership Project), the development of the specifications of a fifth generation mobile communication system NR (New Radio) is performed. NR differs greatly an LTE (Long Term Evolution) is the current mobile communication system, transmission and reception bandwidth of each terminal apparatus may be different (e.g., see Non-Patent Documents 1, 2 and 3.).
[0003]
　Further, in a general mobile communication system, the terminal apparatus transmits with HARQ-ACK (Hybrid Automatic Repeat Request Acknowledgement) information uplink indicating whether or not decoded the data received in the downlink properly. In NR, PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel) is used as a physical channel for transmitting the UCI (Uplink Control Information) containing the HARQ-ACK information.
[0004]
　For example, Patent Document 1, a base station, it is disclosed that notifies the terminal device dynamically determines the PUCCH resource from among the candidates notified in advance the terminal device.
[0005]
　PUCCH used in the NR is expected to be similar in structure and PUCCH format 1 / 1a / 1b to be used in LTE. As one specific common point, and that the frequency hopping in the slot is supported. If frequency hopping is performed in the transmission of such PUCCH, for example, as described in Non-Patent Document 1, since the maximum transmission bandwidth of each the NR of the terminal device may differ in uplink system band it may be necessary to change the transmission band of the (re-tuning). Specifically, the maximum transmission bandwidth is smaller terminal device than the uplink system bandwidth by performing a re-tuning as described above, it may be necessary to perform frequency hopping using both ends of the uplink system band.
[0006]
　Here, the re-tuning involving a change of the center frequency, for example, as described in Non-Patent Document 4, it is necessary to time 200 microseconds from 50 microseconds.

　<< 1. Related Art >>
　As a related technology to the embodiment of the present invention, mainly illustrating a PUCCH (Physical Uplink Control Channel) used in the NR.
[0027]
　In NR, 2 types of PUCCH having different time lengths, i.e., the time length (hereinafter referred to as a "Short PUCCH".) Short PUCCH and the time is long PUCCH (hereinafter referred to as "Long PUCCH".) Exists.
[0028]
　Among, Long PUCCH is composed of 14 from 4 OFDM (Orthogonal Frequency Division Multiplexing) symbols. In Long PUCCH, mainly to be used for coverage improvement it is assumed.
[0029]
　Further, the number of bits of UCI transmitted in Long PUCCH if 2 or less, from the agreement of the far, it is expected that the same structure as the LTE PUCCH format 1 / 1a / 1b.
[0030]
　Specific common point, the frequency hopping in the slot is supported, HARQ-ACK information BPSK modulation scheme of (Binary Phase Shift Keying) or QPSK (Quadrature Phase Shift Keying) that is used, repeated in the time domain that the sequence is multiplied by the modulation symbols, orthogonal cover code in the time domain and the like that can be applied to the UCI and RS (Reference Signal).
[0031]
　In NR, slots is one of the scheduling unit. For Normal CP (Cyclic Prefix), 1 slot is composed of seven or fourteen OFDM symbols.
[0032]
　1 RB (Resource Block) consists of twelve consecutive subcarriers in the frequency domain. Since the time length of the RB in the NR is undefined, in the present embodiment using the "RB" as the "minimum unit of resource allocation in the frequency domain." Further, those referred to as "RB" herein, and what may be referred to as "PRB (Physical Resource Block)."
[0033]
　Figure 1 is a diagram showing a configuration example of a Long PUCCH if configured one slot from 14 OFDM symbols. Specifically, in the configuration example shown in FIG. 1 (A), for the transmission of Long PUCCH, 14 OFDM symbols are used. Long PUCCH having such a configuration, all the OFDM symbols of one slot are realized when available for uplink transmission.
[0034]
　Meanwhile, in the configuration example shown in FIG. 1 (B), for the transmission of Long PUCCH, 10 OFDM symbols are used. This is an example using the slot configuration in TDD (Time Division Duplex). Specifically, after the PDCCH at the beginning of a slot (Physical Downlink Control Channel) is transmitted, a guard interval needed during switching from downlink to uplink is inserted. Subsequently, Short PUCCH and / or SRS behind the slot (Sounding Reference Signal) is transmitted. Is four OFDM symbols for these transmissions use the remaining 10 OFDM symbols are used for the transmission of Long PUCCH.
[0035]
　Figure 2 is a diagram showing a configuration example of a Long PUCCH if configured one slot of seven OFDM symbols. In the configuration example shown in FIG. 2 (A), for the transmission of Long PUCCH, 7 OFDM symbols are used. In the configuration example shown in FIG. 2 (B), for the transmission of Long PUCCH, 4 OFDM symbols are used.
[0036]
　To one of RB included in Long PUCCH, it is possible to multiplex the UCI for the plurality of terminal devices. The multiplexing is realized by using a combination of each of the cyclic terminal device is different from shift and orthogonal cover code. The present embodiment will be described assuming a multiplexing method in the LTE PUCCH format 1 / 1a / 1b.
[0037]
　First, multiple by cyclic shifts, CAZAC the transmission of UCI and RS (Constant Amplitude Zero Auto-Correlation) are realized by using a sequence. CAZAC sequence has the property of self-correlation value is 0 when the cyclic shift amount is non-zero. Cyclic shift represents the shift processing to be sequentially moved to the top end of the series elements. An example of CAZAC sequences include Zadoff-Chu sequence. Further, in LTE, a CAZAC sequence when the sequence length is 12 or 24, CGS (Computer Generated Sequences) are used.
[0038]
　(The u integer from 0 to 11) u × [Delta] T when the time length obtained by equally dividing the time length into 12 1OFDM symbols excluding the CP portion has a [Delta] T by performing the cyclic shift of the twelve largest UCI and multiplexing the RS becomes possible. Here, in order to maintain the orthogonality between the terminal needs to greater than the maximum delay path in the channel the minimum interval of cyclic shifts. In LTE, a cell common parameters delta Shift (delta Shift By using = 1,2,3), the minimum interval delta cyclic shift Shift × [Delta] T is adjusted. Accordingly, the maximum number of multiplexed by cyclic shifts, 12 / delta Shift becomes.
[0039]
　Multiple by orthogonal cover code is realized by performing block spreading the UCI and RS for a plurality of OFDM symbols. The use of orthogonal cover code, it is possible to multiplex by block spreading the sequence length and the same number of complex symbols. Here, orthogonal cover code before and after frequency hopping, UCI, and for each of the RS, are applied independently, the sequence length is equal to the number of OFDM symbols allocated to each. Thus, the maximum number of multiplexed, before and after the frequency hopping, the minimum value of the number of OFDM symbols allocated to each of the UCI and RS.
[0040]
　Maximum number of multiplexed by the orthogonal cover code, 2 become in the configuration example shown in 3, and the FIG. 1 (B) in the case of the configuration example shown in FIG. 1 (A). Meanwhile, in the configuration example shown in each of FIGS. 2 (A) and FIG. 2 (B), the order is RS even after frequency hopping is composed of a single OFDM symbol, is not performed multiplexed by the orthogonal cover code.
[0041]
　Multiplexing number N of UCI per 1RB of Long PUCCH is the maximum number of multiplexed by cyclic shifts is expressed by the product of the maximum number of multiplexed and by the orthogonal cover code. For example, the maximum number of multiplexed by cyclic shift 4 (i.e. delta Shift If the maximum number of multiplexed 3 by = 3) and orthogonal cover code, per 1 RB, 4 × 3 = 12 pieces of UCI is possible multiplexing.
[0042]
　3, delta Shift illustrates, cyclic shift number u, and examples of the combination of orthogonal cover code number c. By referring to the combination as shown in FIG. 3, it is possible to perform the numbering for multiple possible resources 1RB of Long PUCCH. Note that FIG. 3 is one example, for example may be performed differently numbered for each cell.
[0043]
　4, one terminal device is a schematic diagram of a case of transmitting the HARQ-ACK information on Long PUCCH. The base station transmits data of the terminal device addressed on PDSCH (Physical Downlink Shared Channel), and transmits the DCI (Downlink Control Information) including allocation information of the data on the PDCCH (Physical Downlink Control Channel). On the other hand, the terminal device after receiving the DCI to itself as the destination on the PDCCH, for receiving data on the PDSCH based on the DCI. Then, the terminal apparatus transmits an HARQ-ACK information indicating whether or not decoded the data correctly on Long PUCCH in the uplink slot.
[0044]
　In NR, to the terminal device, sub-band (Bandwidth part) composed of successive RB is set separately for uplink and downlink. Incidentally, RB number set in partial band is less than the maximum bandwidth that each terminal device supports. Each of the terminal device, one or more partial bands are set. The terminal device, among the set sub-band, performs reception of downlink signals on the active downlink subbands, performs transmission of the uplink signal using the active uplink sub-bands.
[0045]
　<< 2. Outline of Embodiment of the present invention >>
　First, an overview of an embodiment of the present invention.
[0046]
　(1) technical problem
　with obtaining different maximum transmission bandwidth of each the NR of the terminal device as described above, when the frequency hopping is performed in the transmission of Long PUCCH, for each terminal device, the hopping interval in the frequency domain It may also be different. For example, the maximum transmission bandwidth is smaller terminal device than the uplink system bandwidth for the transmission of Long PUCCH, it may perform frequency hopping in addition to the end of the uplink system band.
[0047]
　Figure 5 is a diagram maximum transmission bandwidth is a specific example of a resource location, each of the small terminal devices A ~ D from the uplink system bandwidth the frequency hopping. Fragmented resource as shown in FIG. 5 may occur. The presence of such fragmented resource is a factor of lowering the degree of freedom of resource allocation of the PUSCH.
[0048]
　Furthermore, the NR, as the transmission waveform of the uplink, it is agreed to use both the CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplexing) and DFT-s-OFDM (Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing) ing. In the case of using the DFT-s-OFDM as the transmission waveform of PUSCH, which is assumed to support only allocation of continuous RB.
[0049]
　Here, considering the presence of a fragmentary RB as shown in Fig. 5 described above, in the case of DFT-s-OFDM is that the number of RB consecutive be allocated to one of the terminal devices is limited Become. In the case of CP-OFDM is susceptible assignment of discontinuous RB, considering the overhead of resource allocation information, resource allocation so as to use all RB present fragmentary is difficult. Therefore, unused RB will increase the utilization efficiency of radio resources may be degraded.
[0050]
　As a method for preventing the occurrence of fragmented resource described above, for example, as disclosed in the following references, by setting a plurality of subbands in the uplink system band, present in the edge of the sub-band transmitting the PUCCH on the resource has been proposed.
　[Reference] CMCC "Discussion on subband-based PUCCH resource allocation and indication", 3GPP TSG RAN WG1 Meeting NR Ad-Hoc # 2. Qingdao, China, 27-30 June 2017. R1-1710782
[0051]
　However, the above references, no no disclosure about what the starting position in RB number and frequency domain subbands provided constraints. Therefore, if that be placed in any position in the frequency domain to any number of RB sub-bands, overhead for notifying the information about the subband to the terminal apparatus is increased.
[0052]
　Here, by performing the re-tuning to change the transmission band in uplink system band, the maximum transmission bandwidth is smaller terminal device than the uplink system bandwidth the frequency hopping using both ends of the uplink system band it becomes possible. However, the re-tuning involving a change of the center frequency, for example, a 50 microseconds required 200 microseconds time. Such in order to perform a re-tuning, for example, requires the insertion of guard interval, OFDM symbol number that can be used to send the Long PUCCH is reduced, may cause coverage reduction.
[0053]
　(2) Technical features
　in embodiments of the present invention, for example, a base station, the communication processing unit in the partial band used by the first terminal device among the uplink system band to communicate with the first terminal device comprises, the partial band includes a physical uplink control channel region used by the first terminal device.
[0054]
　In the embodiments of the present invention, for example, the first terminal apparatus includes a communication processing unit, which communicates with the base station in the first portion band used by the terminal device among the uplink system band, the partial band includes a physical uplink control channel region used by the first terminal device.
[0055]
　According to the embodiment, for example, regardless of the sub-band used by the first terminal device, the first terminal device is able to transmit a physical uplink control channel without re-tuning to the base station . More specifically, possible sub-band of the first terminal device be less than the uplink system band, the first terminal device to transmit the physical uplink control channel without re-tuning to the base station become.

[0080]
　<4.3. Technical features>
　Next, the technical features of the first embodiment.
[0081]
　Base station 100 (communication processing unit 141) communicates with the first terminal device among the uplink system band to the first terminal device in the partial band used by (terminal 200A) (terminal 200A), It said first terminal device (communication processing unit 231 of the terminal device 200A) communicates with the base station 100 within the sub-band. The partial band includes a physical uplink control channel region used by the first terminal (terminal 200A).
[0082]
　Base With such a configuration, for example, regardless of the sub-band used by the first terminal (terminal 200A), a physical uplink control channel without first terminal (terminal 200A) is re-tuning it is possible to transmit to the station 100. More specifically, even partial band of the first terminal device (terminal device 200A) is smaller than the uplink system band, the physical uplink control without first terminal (terminal 200A) is re-tuning it is possible to transmit the channel to the base station 100.
[0083]
　(1) partial band
　the partial band may include a plurality of physical uplink control channel region used by the first terminal (terminal 200A). Here, the plurality of physical uplink control channel region may be spaced apart from each other in the frequency direction.
[0084]
　For example, if the frequency hopping for transmission of a physical uplink control channel is carried out, one of the plurality of physical uplink control channel region, for transmitting the physical uplink control channel before the frequency hopping a region, one of the other physical uplink control channel region may be a region for transmitting the physical uplink control channel after the frequency hopping.
[0085]
　Further, the uplink system band includes a plurality of sub-bands, each of the plurality of sub-bands, comprising a plurality of resource blocks continuous in the frequency direction. In such the uplink system band configuration, the sub-band includes one or more of the plurality of sub-bands.
[0086]
　Also, the partial band may be one or more of the plurality of sub-bands. In other words, the size and position of the partial band may be defined by one or more sub-band.
[0087]
　Furthermore, the partial band may be configured to correspond to the specific Numerology. Specific Numerology is the subcarrier spacing, TTI (Transmission Time Interval), and CP (Cyclic Prefix) may be at least a parameter that is based on any of the Type. The one or more partial bands, CC (Component Carrier) may be set to semi-Static to the terminal device each.
[0088]
　When a plurality of sub-bands for one of the terminal device is set, it may be different Numerology is set to each other for each of the plurality of sub-bands. The different Numerology, for example, the reference sub-carrier spacing f 0 as 15 kHz, the other sub-carrier spacing f sc = 2 n × f 0 and may be a scalable values like. That is, the subcarrier interval may be a scalable value a power of 2. Also, different CP Type for each of the plurality of partial bands may be set. That is, any the respective sub-bands of the Normal CP, and Extended CP may be set.
[0089]
　Furthermore, the first terminal device subbands used by (terminal 200A), the first terminal (terminal 200A) different from the second terminal device (the terminal device 200B) by the partial band used it may include one or more of the sub-bands included in.
[0090]
　It will be described later configuration example of a particular sub-band.
[0091]
　(2) physical uplink control channel region
　the physical uplink control channel region is located in the sub-band contained in the partial band.
[0092]
　For example, when the partial band comprises two or more sub-band, the physical uplink control channel region is located in one of the sub-band of said two or more sub-bands included in the partial band.
[0093]
　Incidentally, the physical uplink control channel region may be located within the sub-band at the end of said two or more sub-band. Here, the sub-bands on the edge, of said two or more sub-bands, the highest subband lowest subband in the frequency direction or the frequency direction.
[0094]
　Here, in the case where the partial band comprises a plurality of physical uplink control channel region apart in the frequency direction each other as described above, each physical uplink control channel region, for example, first and second physical uplink control as a channel region. In this case, the first and second physical uplink control channel region, as one example, located in different sub-bands. That is, the first physical uplink control channel region is located in one of the sub-band of said two or more sub-bands included in the partial band, the second physical uplink control channel region , located within a different one of the sub-bands and sub-bands in the first physical uplink control channel region of the two or more sub-bands included in the partial band is located. Incidentally, the first and second physical uplink control channel region is not limited to the case described above, may be included at a position apart in the frequency direction each other in the same sub-band.
[0095]
　Furthermore, the physical uplink control channel region is located at a predetermined position in the sub-band. Here, the predetermined positions are positions on the edge of the sub-bands, or locations separated by a predetermined distance from the end of the sub-band. For example the physical uplink control channel region, and the end of the sub-band, 20 percent of the width of the sub-bands from the end, 25%, may be positioned between the point distant by 50%.
[0096]
　- Candidate bands
　the physical uplink control channel region may be located in one of the candidate bands of the two or more candidate bands within the sub-bands. It said two or more respective candidate band is one sub-band, or two or more sub-band continuous in the frequency direction within the sub-band within the sub-bands.
[0097]
　For example, the specific position of the first and second physical uplink control channel region is as follows. For example, if composed of the physical uplink control candidate band channel region is located, one sub-band, and the first physical uplink control channel region is located at one end of the corresponding sub-band, the corresponding sub-band It said second physical uplink control channel region is located at the other end. Also, the physical uplink control channel when the area is composed of two or more sub-bands candidate band positions are continuous in the frequency direction, the first physical-up to a sub-band that is located at one end of the said candidate band located link control channel region, the second physical uplink control channel region to the sub-band located at the other end in the candidate band is located.
[0098]
　(3) control information
　the base station 100 (information acquiring unit 143) obtains the first control information for specifying the physical uplink control channel region, the base station 100 (communication processing unit 141) is the first transmitting control information to the first terminal (terminal 200A).
[0099]
　As described above, when the physical uplink control channel region is located in the sub-band contained in the partial band, as the first control information, identifying the sub-band which the physical uplink control channel region is located control information for is used.
[0100]
　As described above, when the physical uplink control channel region is located in one of the candidate band from among the two or more candidate bands within the sub-bands, as the first control information, the control information for the physical uplink control channel region to identify a candidate band located is used.
[0101]
　Specifically, as the first control information, for example, two types of indexes such as the following may be used. First, one index, the index for the physical uplink control channel region to identify a candidate band located from a plurality of candidate bands in the uplink system band (hereinafter, referred to as absolute index.) In is there. Another index, the index for identifying the candidate band in which the physical uplink control channel region is located among the two or more candidate bands within the sub-band (hereinafter, referred to as a relative index.) In is there.
[0102]
　For example, between the base station and the terminal device, when the physical uplink control channel region into sub-bands located at the end of the candidate band is agreement that position, the first terminal (terminal 200A) is by identifying the candidate bands based on the index, it is possible to identify a sub-band in which the physical uplink control channel region is located.
[0103]
　Further, for example, base station 100 (communication processing unit 141), the DCI (Downlink Control Information) containing the index may be transmitted to the first terminal (terminal 200A). Further, the base station 100 (communication processing unit 141), a MAC (Media Access Control) control element including the index may be transmitted to the first terminal (terminal 200A).
[0104]
　If the above candidate bands the physical uplink control channel region is located by the first control information is identified as the base station 100 (information acquiring unit 143), in order to identify the two or more candidate bands the second control information may be acquired. Then, the base station 100 (communication processing unit 141) may transmit the second control information to the first terminal (terminal 200A).
[0105]
　Specifically, the base station 100 (communication processing unit 141), the MAC control element including the second control information is transmitted to the first terminal (terminal 200A). The base station 100 (communication processing unit 141), an RRC (Radio Resource Control) message including the second control information may be transmitted to the first terminal (terminal 200A).
[0106]
　<4.4. Specific Example>
　Next, a specific example of processing performed by the system 1.
[0107]
　(1) Specific examples of the sub-band
　- first embodiment
　Figure 9 is a diagram showing a sub-band according to a first embodiment. In the first embodiment, as shown in FIG. 9, the uplink system band sub-band number N sb by being equally divided in the sub-band is set. Incidentally, RB number N of the uplink system band UL RB is N sb If not divisible, the can be the RB number of the difference between the subband 1 or less according to the following equation as an example.
[Equation 1] where,

N sb RB (n) represents the RB number of n-th sub-band.
[0108]
　As an example, RB number of the uplink system band N UL RB is 275 sub-band number N sb when it is 10, and P = 5, according to the above equation. That is, the fourth sub-band from 0 consists of 28RB, 9 th sub-band from 5 consists of 27RB.
[0109]
　Also, RB number N per sub-band RB may be designated. Here, RB number N of the uplink system band UL RB is N RB when not divisible by, as an example, the RB number of sub-bands located at either end of the uplink system band, N　UL RB mod N RB it may be.
[0110]
　- second embodiment
　Figure 10 is a diagram showing a sub-band according to the second embodiment. In the second embodiment, as shown in FIG. 10, the reserved area is provided.
[0111]
　Here, the reserved area is an area for fixedly securing the Long PUCCH resource for each terminal device. Specifically, the reserved area is, for example, SR (Scheduling Request), and Beam failure recovery request such, Long PUCCH resources for the terminal device to send some request to the base station, and periodic CSI (Channel State Information ) is used as the Long PUCCH resources for sending. Reserved area is, as a resource for such Long PUCCH, it is desirable to RB at both ends of the uplink system band is used. This is to avoid that, the number of RB is reduced dynamically assignable successive By uplink system band is divided by the fixedly allocated resources.
[0112]
　Therefore, in the second embodiment, as shown in FIG. 9, a total of N present on both ends of the uplink system band rsv RB and number of RB the reserved area. Then, in the second embodiment, from the uplink system band N rsv RB excluding pieces of RB RB number N ' UL RB sub-band number N sb is equally divided by. Incidentally, N ' UL RB is N sb when not divisible by, it is possible to make the number of RB's of the difference between the subband 1 or less according to the following equation as an example.
[Equation 2]

　where, N ' sb RB (n) represents the RB number of n-th sub-band.
[0113]
　As an example, RB number of the uplink system band N UL RB is 275 sub-band number N sb is 10, a total of 8RB from the band end portions 4RB is assumed to be reserved. In this case, the P '= 7 according to the above equation. That is, the sixth sub-band from 0 consists of 27RB, 9 th sub-band 7 is composed of 26RB.
[0114]
　Also, RB number N per sub-band RB may be designated. Here, from the uplink system band N rsv RB excluding pieces of RB RB number N ' UL RB is N RB when not divisible by, for example, from the uplink system band N rsv RB bandwidth excluding the number of RB among the RB number of sub-bands located at either end, N ' UL RB　mod N RB may be.
[0115]
　- notification of the configuration of the subband
　above subband number N sb RB number N or per sub-band RB are each cell, each terminal device, or terminal device may be notified for each group it belongs. Further, the sub-band number N sb RB number N per or sub-band RB may be included in RMSI (Remaining Minimum System Information), it may be included in the RRC message.
[0116]
　Also, when the increase in overhead is acceptable, RB number starting RB location and contiguous to each sub-band may be set.
[0117]
　(2) a candidate band embodiment
　the base station 100, for example, when setting the sub-band to the first terminal (terminal 200A), from among the two or more sub-bands included in the partial band setting the two or more candidate bands. Thereafter, when the first terminal device the partial band set in (terminal 200A) is activated, the base station 100 identifies one candidate bands from among the two or more candidate bands , the information indicating the candidate band identified, as the first control information and notifies the first terminal device (terminal device 200A). Thereafter, the first terminal (terminal 200A) transmits a Long PUCCH with RB in the sub-bands located at both ends of the notified candidate band from the base station 100.
[0118]
　For example, candidate bands, the start position SB of the sub-band start subband number L, CSBs is uniquely identified by a combination of. Set value X uniquely identify the combination can be calculated by the following equation.
[Equation 3]

The number of bits at this time set value X is as follows.
[Number 4]

[0119]
　The base station 100, without setting the candidate band may notify directly to the first terminal device by using a MAC control element and / or DCI the setting value X (terminal 200A). In such notification method, for example, sub-band number N sb is the required six bits for transmission of the setting value X in the case of 10. Especially, the case of notifying the setting value X using a DCI, the 6 bits becomes large overhead.
[0120]
　Therefore, the base station 100 notifies in advance the first terminal device the second control information for specifying the two or more candidate bands (terminal 200A). Then, the base station 100, MAC CE and / or using the DCI, the two or more indexes for identifying one of the candidate bands from the candidate zone (the first control information) only the first and transmits to the terminal (terminal 200A). This makes it possible to reduce the number of bits for identifying a candidate band the physical uplink control channel region is located.
[0121]
　Next, a description will be given candidate band sub-band is set for two different types of terminal groups. First, the sub-band is an uplink system band and the same bandwidth is set in the terminal group A, sub-band is smaller bandwidth than the uplink system band and shall be set to the terminal groups B. As an example, when the uplink system bandwidth is 50 MHz, the terminal group A is composed of a plurality of terminal devices maximum transmission bandwidth is 50 MHz, a plurality of terminal devices terminal group B is the maximum transmission bandwidth is 25MHz in constructed. For example, the first terminal (terminal 200A) is included in the terminal group B, the second terminal (terminal 200B) is included in the terminal group A. The portion bandwidth because it is less than the maximum transmission bandwidth of the terminal device, the terminal group B may include terminal devices maximum transmission bandwidth is 50 MHz.
[0122]
　Figure 11 is a diagram showing a specific example of the two or more candidate bands set in the terminal group A. As shown in FIG. 11, when the eight candidate bands in the terminal group A is set, the setting value table of Table 1 below is reported as the second control information given. As the notification method setting value table, for example, it can be used RRC message and / or MAC CE.
[0123]
[Table 1]

[0124]
　Base station 100, from among the candidate bands, using a MAC CE and / or DCI, and notifies the index m of candidate bands the physical uplink control channel region is located in the terminal group A. Since this number of bits required for notification is 3, it is possible to reduce the number of bits in comparison with the case of directly notifying the set value X by using the 6 bits as described above.
[0125]
　Figure 12 is a diagram showing a specific example of the two or more candidate bands set in the terminal group B. As shown in FIG. 12, if the four candidate band is set to the terminal group B, for example, setting value X may specify the absolute index, or by the relative indexes.
[0126]
　In the specific example shown in FIG. 12, the absolute index, for example, based on the absolute subband number that uniquely identifies the sub-band # 0 to # 9 each included in the uplink system band, identifying a candidate band for each It is possible. Further, the relative index, for example, sub-band (# 0) of each included in the partial band ~ (# 3) as a reference that uniquely identifies the relative sub-band number, it can be identified candidate bands for each is there.
[0127]
　If the absolute index is used, the following settings table of Table 2 are reported as the second control information given. Here, "the sub-band of the start position SB start " indicates the starting position relative to the absolute subband number. As the notification method setting value table, for example, it can be used RRC message and / or MAC CE.
[0128]
[Table 2]

[0129]
　If the relative index is used, the setting value table of Table 3 below is reported as the second control information given. Here, "the sub-band of the start position SB start " indicates the starting position relative to the relative sub band number. As the notification method setting value table, for example, it can be used RRC message and / or MAC CE.
[0130]
[table 3]

[0131]
　Table 2 and Table 3, the number of bits required for the notification setting table, 6 × 4 = 24 in the case of using the absolute index, when using a relative index is 4 × 4 = 16 is there. Therefore, when the number of bits is variable, it is possible to reduce the number of bits by using a relative index. On the other hand, there is an advantage that the absolute If the index is used, it is possible to perform partial band set between the set value table of notification and the independently.
[0132]
　- Physical Uplink Control alert candidate bands having a channel region located example
　after the above setting value table is notified to each terminal groups A and B, a base station 100, the candidate band used for transmitting the HARQ-ACK information the index m, that is, the physical uplink control channel region is notified to the terminal device the index m of candidate bands located.
[0133]
　As a notification method for the index m, may DCI is used for scheduling PDSCH corresponding to the HARQ-ACK information. Thus, each transmission of PDSCH, that is able to notify the dynamic index m for each transmission of HARQ-ACK information enables scheduling flexible uplink.
[0134]
　Also if the DCI includes a repetition number The, the index m, as dynamically switched every number of subframes corresponding to the repetition number The, the system may be set. Further DCI may also include control information indicating to be switched dynamically by the number of subframes corresponding index m to repetition number The. Incidentally index m may be different in subframe each other are repeatedly transmitted, control information indicating this may be included in the DCI.
[0135]
　In the case of dynamic control is not required, it may notify the index m by using an RRC message and / or MAC CE.
[0136]
　Figure 13 is a diagram showing the position of Long PUCCH used respectively by the terminal group A and terminal group B. Notification example shown in FIG. 13, and notifies the index m = 2, 3, 6 to the terminal group A, it is assumed that notifies the index m = 3 to the terminal groups B. Band sub-band number band from 0 (absolute subband number in the example of FIG. 13) # to # 2, the band of the sub-band number from # 3 to # 6, and the sub-band number from # 7 to # 9 in each, it is possible to use a portion other than the Long PUCCH as a continuous band that can be assigned to the transmission of the PUSCH.
[0137]
　Thus, the terminal group A and terminal group B is active partial band are different from each other, by using a physical uplink control channel region located in a common sub-band, all of Long PUCCH, the common sub it can be assigned to concentrate near the boundary of the band. Thus, Long PUCCH is efficiently multiplexed, and it is possible to suppress the fragmentation of radio resources.
[0138]
　- arrangement example of a physical uplink control channel region in the sub-band or candidate band
　terminal devices, together with the sub-band or candidate band physical uplink control channel region for transmitting HARQ-ACK information is located, the sub it is necessary to identify the relative resource number for Long PUCCH resources in-band or in the candidate zone. This relative resource number, relative RB number and resource numbers in the RB may be specified in the sub-band or candidate band. Resource number in the RB may be intended to identify cyclic shift number and / or an orthogonal cover code number is applied to a Long PUCCH.
[0139]
　Note that when the frequency hopping is performed, a physical uplink in after the relative resource number, relative position in the physical uplink control channel sub-band region or candidate band in front of the frequency hopping, or frequency hopping at least one of relative position in the sub-band of the control channel region or candidate band may be configured to identify.
[0140]
　Figure 14 is a diagram for explaining a specific example of relative resource numbers for Long PUCCH resources in sub-band or candidate band.
[0141]
　This relative resource number based on the information about the resources PDSCH is transmitted corresponding to the HARQ-ACK information may be implicitly determined. Examples of this information, PDSCH is scheduled beginning of the OFDM symbol number or RB number, the last OFDM symbol number or RB ID, or any combination thereof.
[0142]
　The relative resource numbers, based on the information on PDCCH resource DCI is transmitted for scheduling PDSCH, it may be determined implicitly. Examples of this information, OFDM symbol number or RB number of the head to which the PDCCH is transmitted, the last OFDM symbol number or RB number, the head or final index REG (Resource Element Group), CCE (Control Channel Element) top or final index, or any combination of thereof.
[0143]
　The relative resource number may be specified directly in the MAC CE and / or DCI.
[0144]
　In addition, some of the relative resource number is specified directly by the MAC CE and / or DCI, the rest may be determined by the implicit method described above.
[0145]
　Long PUCCH frequency hopping on / off time of transmission for each terminal, each partial band set in the terminal, or may be semi-statically specified for each candidate band. Or by including a flag indicating the on / off frequency hopping DCI, may be dynamically specified.
