Terminal device 2 monitors the one or more sets of PDCCH candidates Activating been serving cell and / or EPDCCH set of candidate set by RRC signaling. Here, the monitoring is to attempt to decode PDCCH and / or EPDCCH in the set corresponding to the DCI format to be all monitors.
[0125]
　Set of the set or the EPDCCH candidate of PDCCH candidates are also referred to as a search space. The search space, shared search space (CSS) and the terminal-specific search space (USS) is defined. CSS may be defined only for the search space on the PDCCH.
[0126]
　CSS (Common Search Space) is a search space that is set on the basis of specific parameters and / or predefined parameters to the base station apparatus 1. For example, CSS is a search space used in common by a plurality of terminal devices. Therefore, the base station apparatus 1 by mapping the common control channel by a plurality of terminal devices to CSS, resources for transmitting is reduced control channel.
[0127]
　USS (UE-specific Search Space) is a search space that is set using the parameters specific to at least the terminal device 2. Therefore, USS is a unique search spaces on the terminal device 2, the base station apparatus 1 can transmit individual-specific control channel to the terminal device 2 by USS. Therefore, the base station apparatus 1 can efficiently mapping specific control channels to a plurality of terminal devices.
[0128]
　USS may be set to be used in common to a plurality of terminal devices. For common USS is set to a plurality of terminal devices, parameters specific to the terminal apparatus 2 is set to be the same value among the plurality of terminal devices. For example, unit set to the same parameters between the plurality of terminal devices, cell, and the like transmission point or a group of a predetermined terminal device.
[0129]
　Search space of aggregation level each is defined by a set of PDCCH candidates. Each PDCCH, are transmitted using a set of one or more CCE (Control Channel Element). The number of CCE used for one PDCCH is also aggregation level is referred. For example, the number of CCE's used for one PDCCH is 1, 2, 4 or 8.
[0130]
　Search space of aggregation level each is defined by a set of EPDCCH candidate. Each EPDCCH, is transmitted using a set of one or more ECCE (Enhanced Control Channel Element). The number of ECCE used in one EPDCCH is also aggregation level is referred. For example, the number of ECCE used in one EPDCCH is 1,2,4,8,16 or 32.
[0131]
　Count of the number or EPDCCH candidates PDCCH candidates is determined based on at least the search space and aggregation level. For example, in CSS, the number of PDCCH candidates in aggregation level 4, and 8 are respectively 4 and 2. For example, in the USS, the number of PDCCH candidates in aggregation 1, 2, 4, and 8 are each 6,6,2 and 2.
[0132]
　Each ECCE is composed of a plurality of EREG (Enhanced resource element group). EREG is used to define the mapping for resource elements EPDCCH. In each RB pair are numbered from 0 to 15, 16 EREG is defined. That is, in each RB pair, EREG0 ~ EREG15 are defined. In each RB pair, EREG0 ~ EREG15, relative to resource elements other than resource elements in which a predetermined signal and / or channel is mapped, in favor of a frequency direction, it is periodically defined. For example, resource elements EPDCCH demodulation reference signal associated with the transmitted on antennas ports 107-110 are mapped are not defined as EREG.
[0133]
　The number of ECCE used in one EPDCCH depends on EPDCCH format is determined based on other parameters. The number of ECCE used in one EPDCCH is also aggregation level is referred. For example, the number of ECCE used in one EPDCCH the number of resource elements which can be used for EPDCCH transmission in one RB pair based the like on the transmission method of EPDCCH, is determined. For example, the number of ECCE used in one EPDCCH is 1,2,4,8,16 or 32. The number of EREG used in one ECCE is determined based on the type and the type of cyclic prefix sub-frame, 4 or 8. Method of transmitting the EPDCCH, distributed transmission (Distributed Transmission) and localized transmission (the Localized Transmission) is supported.
[0134]
　EPDCCH may use distributed transmission or localized transmission. Distributed transmission and localized transmission, the mapping of ECCE is different for EREG and RB pair. For example, in a distributed transmission, one ECCE is constructed of a EREG multiple RB pairs. In localized transmission, one ECCE is constructed of a EREG one RB pair.
[0135]
　The base station apparatus 1 to the terminal device 2 performs the setting for EPDCCH. Terminal device 2, based on the setting from the base station apparatus 1, for monitoring a plurality of EPDCCH. Set of RB pairs terminal device 2 for monitoring the EPDCCH can be set. Set of RB pair are referred to as EPDCCH set or EPDCCH-PRB set. To one of the terminal device 2 can be set more than one EPDCCH set. Each EPDCCH set consists of one or more RB pairs. Also, settings for EPDCCH can be performed separately for each EPDCCH set.
[0136]
　The base station apparatus 1 to the terminal device 2, can be set EPDCCH set of a predetermined number. For example, EPDCCH set up to two, as EPDCCH set 0 and / or EPDCCH set 1 can be set. Each EPDCCH set, can be constituted by a predetermined number of RB pairs. Each EPDCCH set constitute one set of ECCE. The number of ECCE constructed in one EPDCCH sets, the number of RB pairs is set as the EPDCCH set, and, based on the number of EREG used in one ECCE, it is determined. If the number of ECCE constructed in one EPDCCH sets is N, each EPDCCH set constitutes the ECCE, numbered 0 ~ N-1. For example, when the number of EREG used in one ECCE is 4, the EPDCCH set composed of four RB pairs constituting 16 ECCE.

[0149]
　　
　The base station apparatus 1, as a method for resource allocation of PDSCH and / or PUSCH to the terminal device 2, can be used several ways. The method of resource allocation include dynamic scheduling, semi-persistent scheduling, multi-subframe scheduling, and cross subframe scheduling.
[0150]
　In dynamic scheduling, one DCI performs resource allocation in one subframe. Specifically, PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PDSCH in that subframe. PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PUSCH in a given subframe after that sub-frame.
[0151]
　In the multi-subframe scheduling, one DCI performs resource allocation in one or more sub-frames. Specifically, PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PDSCH in one or more sub-frames after the predetermined number than the sub-frame. PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PUSCH in one or more sub-frames after the predetermined number than the sub-frame. The predetermined number may be an integer greater than or equal to zero. The predetermined number may be predefined, may be determined on the basis of the physical layer signaling and / or RRC signaling. In the multi-subframe scheduling may be contiguous subframes Scheduling, subframe having a predetermined period may be scheduled. The number of subframes to be scheduled may be predefined, may be determined on the basis of the physical layer signaling and / or RRC signaling.
[0152]
　In cross subframe scheduling, one DCI performs resource allocation in one subframe. Specifically, PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PDSCH in one sub-frame after the predetermined number than the sub-frame. PDCCH or EPDCCH in a certain sub-frame, performs scheduling for PUSCH in one subframe after the predetermined number than the sub-frame. The predetermined number may be an integer greater than or equal to zero. The predetermined number may be predefined, may be determined on the basis of the physical layer signaling and / or RRC signaling. In cross subframe scheduling may be contiguous subframes Scheduling, subframe having a predetermined period may be scheduled.
[0153]
　In semi-persistent scheduling (SPS), one DCI performs resource allocation in one or more sub-frames. The terminal apparatus 2, information about the SPS is configured by RRC signaling, when detecting a PDCCH or EPDCCH to enable SPS, to enable processing regarding SPS, given PDSCH and / or on the basis of the settings relating to SPS PUSCH to receive. Terminal device 2, if the SPS finds the PDCCH or EPDCCH to release the SPS when it is effective, the SPS release (disable) to stop the reception of the predetermined PDSCH and / or PUSCH. SPS release may be performed on the basis of when a predetermined condition is satisfied. For example, when receiving the data of a predetermined number of empty transmission, SPS is released. Empty transmission of data to release the SPS corresponds to MAC PDU including zero MAC SDU (Service Data Unit) (Protocol Data Unit).
[0154]
　Information about the SPS by RRC signaling, SPS C-RNTI is an RNTI of SPS, information about the period (interval) to be scheduled for PDSCH, information on the period (interval) to be scheduled for PUSCH, on setting for releasing the SPS information, and / or a number of HARQ processes in SPS. SPS is supported only on the primary cell and / or primary secondary cell.
[0155]
　　
　In the present embodiment, HARQ has various features. HARQ is to transmit and retransmit the transport block. In HARQ, a predetermined number of processes (HARQ process) is used (set), each process operates independently in stop-and-wait method.
[0156]
　In downlink, HARQ is asynchronous, operates adaptively. That is, in the downlink, retransmissions are always scheduled via PDCCH. Uplink HARQ-ACK corresponding to the transmission downlink (response information) is transmitted on PUCCH or PUSCH. In the downlink, PDCCH is, HARQ process number indicating the HARQ process, and notifies the information indicating whether retransmission thereof or transmission initial transmission.
[0157]
　In uplink, HARQ operates synchronously or asynchronously. Downlink HARQ-ACK corresponding to uplink transmission (response information) is transmitted in PHICH. In uplink HARQ, operation of the terminal device is determined based on the PDCCH received by the HARQ feedback and / or the terminal device is received by the terminal device. For example, PDCCH is not received, if HARQ feedback is ACK, the terminal apparatus does not perform transmission (retransmission), holds the data in the HARQ buffer. In that case, it may PDCCH is sent to resume retransmission. Further, for example, PDCCH is not received, if HARQ feedback is NACK, the terminal device performs a non-adaptive retransmission in a given uplink subframe. For example, when the PDCCH is received, regardless of the content of the HARQ feedback, the terminal device based on the content to be notified by the PDCCH, performs transmission or retransmission.
[0158]
　Incidentally, in the uplink, when a predetermined condition is satisfied (setting), HARQ may be operated only asynchronously. In other words, the downlink HARQ-ACK is not sent may be scheduled through always PDCCH retransmission in the uplink.
[0159]
　In HARQ-ACK report, HARQ-ACK indicates the ACK, NACK or DTX,. If HARQ-ACK is ACK, the transport block corresponding to the HARQ-ACK (codeword, channels) indicates that the correctly received (decoded). If HARQ-ACK is NACK, indicating that the HARQ-ACK in the corresponding transport block (codeword, channels) that could not be correctly received (decoded). If HARQ-ACK is DTX, indicating that the transport block corresponding to the HARQ-ACK (codewords, channel) does not exist (not transmitted).
[0160]
　In each of the downlink and uplink, a predetermined number of HARQ processes is set (defined). For example, in FDD, up to eight HARQ process is used for each serving cell. Further, for example, in TDD, the maximum number of HARQ processes is determined by the uplink / downlink configuration. The maximum number of HARQ processes may be determined based on the RTT (Round Trip Time). For example, if the RTT is 8 TTIs, the maximum number of HARQ processes can be 8.
[0161]
　In the present embodiment, HARQ information consists of at least NDI (New Data Indicator) and TBS (transport block size). NDI is information indicating whether retransmission transport block is initially transmitted corresponding to the HARQ information. TBS is the size of the transport block. Transport block is a block of data in the transport channels (Transport Layer) can be a unit of HARQ. In DL-SCH transmission, HARQ information includes a further HARQ process ID (HARQ process number). In UL-SCH transmission, HARQ information further comprises an RV (Redundancy Version) is information for specifying the information bits and parity bits after encoding for the transport block. For spatial multiplexing in DL-SCH, the HARQ information includes a set of NDI and TBS for each transport block.

　In NR, a physical channel and / or physical signal may be transmitted by the self-contained transmission (self-contained transmission). Figure 13 shows an example of a frame structure of a self-contained transmission in the present embodiment. The self-contained transmission, one transmission and reception, the downlink successive transmissions from the head, GP, and consists of consecutive downlink transmission order. The successive downlink transmission includes at least one downlink control information and DMRS. As downlink control information instructing transmission of the uplink physical channel included in the uplink transmission to reception, or continuous downlink physical channels included in a downlink transmission to the continuous. If the downlink control information instructs the receiving of the downlink physical channel, the terminal device 2 attempts to receive the downlink physical channel based on the downlink control information. Then, the terminal apparatus 2, the reception success or failure of the downlink physical channel (decoding success or failure), and transmits the uplink control channel included in the uplink transmission to be allocated after GP. On the other hand, if the downlink control information instructs the transmission of the uplink physical channels, for transmission, including the uplink physical channel transmitted based on the downlink control information on uplink transmission. Thus, the downlink control information, by switching flexibly transmit the transmission and downlink data uplink data, it is possible to respond immediately to changes in the traffic ratio of uplink and downlink. Further, by notifying in uplink transmission immediately after the reception success or failure of the downlink, it is possible to realize low delay communication of the downlink.
[0173]
　Unit slot time, downlink transmission, the smallest time unit to define a GP or uplink transmission. Unit slot time, downlink transmission, is reserved for either the GP or uplink transmission. Some unit slot time, both the downlink transmission and uplink transmission is not included. Unit slot time may be the minimum transmission time of the channel associated with the DMRS included in the unit slot time. One unit slot time is, for example, the sampling interval (T a NR s is defined as an integer multiple of) or symbol length.
[0174]
　A unit frame time may be a minimum time specified by the scheduling. A unit frame time may be a minimum unit which a transport block is transmitted. Unit slot time may have a maximum transmission time of the channel associated with the DMRS included in the unit slot time. A unit frame time may be a unit time for determining the uplink transmission power in the terminal device 2. A unit frame period, may be referred to as a subframe. Units frame time, downlink transmission only, uplink transmission only, three types of combinations of uplink transmission and downlink transmission are present.

　orthogonal multiple access: In (Orthogonal Multiple Access OMA), performs transmission and reception using a frequency axis and a time axis for example orthogonal. At this time, as shown in FIG. 6, a frame configuration of frequency and time resources are determined by the subcarrier spacing can not be used more than the number of resources a resource element.
[0177]
　On the other hand, in the NOMA, in addition to the frequency axis and time axis orthogonal, non-orthogonal axes, for example, Interleave pattern axis, Spreading Pattern axis, Scrambling Pattern axis, Codebook axis, by adding such Power shaft, a frame construction There are determined.
[0178]
　Figure 14 is an explanatory diagram showing an example of NOMA transmission process. For example, Figure 14 is a resource to be multiplexed in multiplexed transmission signal in a non-orthogonal axes in the transmitting apparatus, and a non-orthogonal axis represents all cases the same parameter set. Here, the transmitting device indicates one of the base station apparatus 1 or the terminal apparatus 2. In transmitting apparatus, to prepare a plurality of transmission signal set for the multiplex. In Figure 14, multiplexes two transmission signal set. Here are two and may be three or more transmission signal set. Also, each of the transmission signal set may be a transmission signal for the separate receiving device may be a transmission signal for the same receiver. Here, the receiving device indicates one of the base station apparatus 1 or the terminal apparatus 2. Each transmission signal set corresponding NOMA Pattern Vector is applied. NOMA Pattern Vector is an example of information on non-orthogonal multiplexing. Here, the NOMA Pattern Vector, for example, Interleave pattern, Spreading Pattern, Scrambling Pattern, Codebook, Power Allocation, and the like. Furthermore, here have been called NOMA Pattern Vector, simply be under the designation such Pattern and Index, may refer to a representation of Pattern or Index such identifiers and Pattern itself for use in NOMA as listed above as an example . NOMA Pattern Vector after application of signals are multiplexed on the same frequency and time resource are sent to the same antenna port. Although multiplexed transmission signal set of the same parameter set 14, as shown in FIG. 15, it may be multiplexed transmission signal set for the different parameter sets. 15 except that multiplex transmit signal set of different parameter sets are the same as those in FIG.
[0179]
　16 and 18 is an explanatory diagram showing an example of NOMA transmission process. On the other hand, as shown in FIG. 16 and 18, without multiplexing at the transmitting device, it transmits a signal to which the NOMA Pattern Vector, a method for the transmission to be non-orthogonal multiplexing at a receiving apparatus are also contemplated. Each transmission signal set corresponding NOMA Pattern Vector is applied. Here, the NOMA Pattern Vector, for example, Interleave pattern, Spreading Pattern, Scrambling Pattern, Codebook, Power Allocation, and the like. Signal after NOMA Pattern Vector applied is transmitted on the same frequency and time resources are multiplexed through a propagation channel. In this case, each of the transmission signal set may be transmitted from different transmitting devices. Further, as shown in FIG. 17, a parameter set of the transmission signal transmitted on the same frequency and time resources may be a different set of parameters.
[0180]
　Figure 18 is an example of a receiving apparatus that performs NOMA reception processing. As shown in FIG. 18, the received signal is received in a state where a plurality of transmission signals are multiplexed on the same frequency and time resources. In the receiving apparatus for decoding a multiplexed transmission signal set, to apply the NOMA Pattern Vector applied at the transmitter, the channel equalization and interference signal canceller retrieve a desired signal. At this time, if you've multiple used the same NOMA Pattern Vector, the influence of interference between multiplexed signals becomes large, it becomes difficult to decode.
[0181]
　As described above, in the NOMA sends share NOMA Pattern Vector applied by the transmission apparatus and the receiving apparatus between the transmitter and receiver, and it is necessary to NOMA Pattern Vector is applied without overlapping.
[0182]
　　
　As described above, in NOMA transmission application techniques NOMA Pattern Vector is important. From here, a description for the determination method and the notification method of application to NOMA Pattern Vector.
[0183]
　For example, assuming a downlink transmission, the base station apparatus 1 selects a NOMA Pattern Vector available from the NOMA Pattern Vector, after applying the NOMA Pattern Vector, the applied NOMA Pattern Vector, the terminal apparatus 2 RRC Signaling, System Information Block (SIB), may notify the like DCI. For downlink transmission, the base station apparatus 1 can determine a resource allocation of a plurality of terminal devices 2. Even without changing the dynamic NOMA Pattern Vector, the base station apparatus 1, the plurality of terminal devices 2, once once by assigning NOMA Pattern Vector, a plurality of terminal devices 2 that same NOMA Pattern Vector is assigned even when the transmission for, by allocating different frequency resources or time resources, it is possible to transmit without increasing the interference between the terminal devices 2.
[0184]
　On the other hand, assuming that the uplink transmission or the side link transmission, the terminal device 2 knows currently available NOMA Pattern Vector before transmission, or determining method is required. For example, there is no problem if the terminal device 2 can receive and resource allocation information and NOMA Pattern Vector information notified from DCI. However, for example, Grant-free Based transmission or such as Out-of-Coverage D2D, if the terminal device is assumed use case of not receiving the DCI, it is necessary to apply methods and notification methods NOMA Pattern Vector.
[0185]
　　
　The Grant-free based transmission, without the terminal device 2 receives the resource allocation from the base station apparatus 1 (Grant), the terminal device 2 by using the appropriate resource transmission representing the to things. Wherein the resource is a separated resource on the frequency axis and time axis. It resource may be selected from all available bandwidth may be selected from among the predetermined resource pool. When selecting from among the predetermined resource pool, the portion of the resources in the resource pool to transmit the signal transmitted from the base station apparatus 1, may be a resource after a predetermined time. Resource pools may be determined statically as a specification, or may be specified when a connection is established with the base station apparatus 1. Since the terminal device 2 can be selected freely the resources used, may compete with resources another terminal apparatus 2 has selected. Because when a conflict in which each signal is an interference signal, the reception signal quality is deteriorated. Therefore, by applying the NOMA techniques Grant-free based transmission, the frequency axis and time axis, and further adding a non-orthogonal axes, even if a conflict on the frequency axis and time axis resource occurs, the non-orthogonal axes it is possible to separate the signals.
[0186]
　However, the case further resource conflicts in a non-orthogonal axes (in particular, NOMA Pattern Vector contention) can also occur.
[0187]
　Here, the Grant-free based transmission, keep clearly the differences between the above-mentioned semi-persistent scheduling (SPS). SPS in advance information about the SPS is configured by RRC signaling, when receiving the PDCCH or EPDCCH to enable SPS, and transmits without Grant based on the settings for SPS. On the other hand, Grant-free based transmission, without receiving the PDCCH or EPDCCH, with features such transmits without Grant.
[0188]
　　
　As described above, by applying the NOMA techniques Grant-free Based transmission, and can be implemented more highly reliable Grant-free based transmission It becomes, but at the resource in the non-orthogonal axes conflict cases exist that occur. Considering such a case, the base station apparatus 1, it is in some use cases preferable to perform communication to keep the reliability by sending an ACK / NACK to the terminal device 2. However, the Grant-free based transmission, since no a Grant to the terminal device 2, since the base station apparatus 1 is difficult to determine which terminal device 2 is a Grant-free based transmission , it is difficult to return the ACK / NACK to a particular terminal device 2. So the base station apparatus 1 transmits the ACK / NACK to the broadcast. The ACK / NACK information includes the ACK / NACK information corresponding to all NOMA Pattern Vector. For example, the ACK / NACK information corresponding to the N NOMA Pattern Vector V AN, 0 ~ V AN, N-1 when the base station apparatus 1 transmits broadcast information represented by Equation 1. Here, the ACK / NACK information corresponding to the n-th NOMA Pattern Vector V AN, n is set to.

[0190]
　In Equation 1, the bit sequence 111 represents ACK, 000 is to represent a NACK. The relationship between the bit sequence and ACK / NACK may be reversed, and the number of bits may be increased or decreased. Or may be the power 0 is the time of NACK. For example, if the power 0, the communication device on the receiving side, it is also possible to determine the ACK / NACK from the receiving power of each resource. Resources used as broadcast transmission, for example, to the base station apparatus 1 may be previously specified in advance, or the like may be pre-determined symbol or sub-carrier, in Grant-free based transmittable in a resource pool.
[0191]
　Figure 19 is an explanatory drawing showing resource pools examples for transmission Grant-free based. The base station apparatus 1 in each of the resource blocks available in the resource pool, as shown in FIG. 19, may be the above notification. For example, since the number of resource blocks available in the case of FIG. 19 is 36, the base station apparatus 1 performs the broadcast transmission of the ACK / NACK for each resource block.
[0192]
　Figure 20, Figure 21 is an explanatory diagram showing an example of a resource for ACK / NACK information. Figure 20 is an example of a resource for ACK / NACK information when arranged solidified information bits. Figure 21 is an information bit is an example of ACK / NACK information for the resources that were staggered on frequency and time directions. As shown in FIG. 21, the information bits by staggered in frequency and time directions, it is possible to obtain a frequency and time diversity. The timing of performing HARQ broadcast transmission may be returned in the same unit frame period, to the timing may be determined statically, or at a timing at which the base station device 1 has been specified. When the base station device 1 designates the timing notifies the timing of HARQ broadcast or the like to the terminal device 2 RRC Signaling.
[0193]
　The terminal apparatus 2, after the Grant-free based transmission, decodes the ACK / NACK broadcast return area after a predetermined timing in advance. The predetermined timing, for example, may be determined statically, at connection establishment with the base station apparatus 1 may be specified by the base station apparatus 1 and the like RRC Signaling.
[0194]
　After data decoding, the terminal apparatus 2 reads the ACK / NACK information corresponding to the NOMA Pattern Vector used during Grant-free based transmission, performs ACK or NACK Kano judgment. If if was NACK, the terminal device 2 performs the procedure of retransmission. In this case, the terminal device 2 performs retransmission at a predetermined resource or resource pool. It timing of retransmission may be determined statically, it may be informed information about the timing from the base station apparatus 1. Upon retransmission may be carried out Grant-free based transmission as well as in the initial transmission. In this case, check the available NOMA Pattern Vector again if necessary, may be carried out Grant-free based transmission using the available NOMA Pattern Vector. Or, the terminal device 2, when receiving the NACK, may transmit a Scheduling Request (SR) to the base station apparatus 1. Terminal device 2 transmits the SR using a pre-specified resource from the resource or the base station apparatus 1 is determined statically. The base station apparatus 1 receives the SR is to reserve resources for the terminal device 2 or NOMA Pattern Vector,, it notifies the terminal apparatus 2. Terminal device 2 having received the notification, using the specified resource or NOMA Pattern Vector, to implement the retransmission. Here, the base station apparatus 1, without receiving the SR from the terminal apparatus 2, to secure the resources for NOMA Pattern Vector became reception failure if necessary, may notify the reception failure.
[0195]
　Figure 22 is a flow diagram illustrating at ACK / NACK transmission embodiment, an example of the operation of the base station apparatus 1 and terminal apparatus 2.
[0196]
　The terminal device 2 confirms whether connection request and Grant-free based transmission possible for the base station apparatus 1 (step S101). The base station apparatus 1, Grant-free based transmission is possible, to ensure if necessary resource pools for transmission Grant-free based (step S102), the establishment and resource connection to the terminal device 2 the position specification of the pool (step S103).
[0197]
　Then, the base station apparatus 1 periodically transmits the NOMA Pattern Vector information (step S104). Terminal device 2 reads the NOMA Pattern Vector information that is periodically transmitted from the base station apparatus 1, by using available NOMA Pattern Vector, generates a transmission signal (step S105). Thereafter, the terminal apparatus 2 selects any resource from the resource pool, and transmits the generated transmission signal (step S106).
[0198]
　The base station apparatus 1 receives the signal, decodes the signal using the NOMA Pattern Vector used (step S107), one of the ACK / NACK or power 0, transmits a resource corresponding to NOMA Pattern Vector (step S108). The terminal device 2 confirms the ACK / NACK at the specified retransmission timing (step S109). The terminal apparatus 2, if the receive ACK from the base station apparatus 1 (step S109, Yes) and terminates the process. On the other hand, the terminal device 2, if receives a NACK from the base station apparatus 1 (step S109, No), carrying out the procedure of retransmission. Procedures for retransmission by the terminal apparatus 2 reads the NOMA Pattern Vector information periodically transmitted from the base station apparatus 1, by using available NOMA Pattern Vector, is resumed from where to generate the transmitted signals.
[0199]
