Description

Terminal, wireless communication method and base station

[0001] The present disclosure relates to a terminal, a wireless communication method, and a base station in a next-generation mobile communication system.

[0002] Long Term Evolution (LTE) has been specified for the Universal Mobile Telecommunications System (UMTS) network with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified with the aim of achieving higher capacity and more advanced features than LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9).

[0003] Successor systems to LTE (e.g., 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 or later, etc.) are also being considered.

[0004] 3GPP TS 36.300 V8.12.0 “Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 (Release 8)”, April 2010

[0005] In future wireless communication systems, a UE will be able to use one of multiple panels (or multiple beams) for uplink (UL) transmission. Furthermore, in Rel. 18 and later, support for simultaneous transmission across multiple panels (STxMP) is being considered to improve UL throughput and reliability.

[0006] However, there has been insufficient consideration on how to control UL transmission using multiple panels (e.g., simultaneous UL transmission) when it is supported. If UL transmission using multiple panels is not performed appropriately, there is a risk of degradation in system performance, such as a decrease in throughput.

[0007] Therefore, one of the objectives of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can appropriately control UL transmission even when UL transmission is performed using multiple panels.

[0008] A terminal according to one aspect of the present disclosure includes: a control unit that applies different UE operations in UL transmission when multiple uplink control channels (PUCCHs) associated with different transmission / reception points or different control resource set pool indices overlap in the time domain, based on at least one of a feedback mode of a delivery acknowledgement signal (HARQ-ACK) and content included in uplink control information (UCI) corresponding to each of the multiple PUCCHs; and a transmission unit that transmits at least one of the multiple PUCCHs.

[0009] According to one aspect of the present disclosure, even when UL transmission is performed using multiple panels, UL transmission can be appropriately controlled.

[0011] (Single Panel Transmission) Single panel UL transmission or a candidate single panel UL transmission scheme may employ at least one of the following transmission schemes A and B (single panel UL transmission schemes A and B). In the present disclosure, panel / UE panel may be interpreted as a UE capability value set (e.g., a UE capability value set) reported for each UE capability. In the present disclosure, different panels, different spatial relationships, different joint TCI states, different TPC parameters, different antenna ports, etc. may be interpreted as interchangeable terms.

[0012] <Transmission Scheme A: Single Panel Single TRP UL Transmission> In Rel. 15 and Rel. 16, a transmission scheme is used in which a UE transmits UL for one TRP from only one beam and panel at one time (FIG. 1A).

[0013] <Transmission Scheme B: Single Panel Multi-TRP UL Transmission> Rel. 17 considers UL transmission from only one beam and panel at a time and repeated transmission for multiple TRPs (Fig. 1B). In the example of Fig. 1B, the UE transmits a PUSCH from panel #1 to TRP #1 (switching beams and panels), and then transmits a PUSCH from panel #2 to TRP #2. The two TRPs are connected via an ideal backhaul.

[0014] (Multi-panel Transmission) In Rel. 18 and later, in order to improve UL throughput / reliability, support for simultaneous UL transmission using multiple panels (e.g., simultaneous multi-panel UL transmission (STxMP)) for one or more TRPs is being considered. Also, a multi-panel UL transmission scheme is being considered for a specific UL channel (e.g., PUSCH / PUCCH).

[0015] For example, a maximum of X panels (e.g., X = 2) and a maximum of Y panels (e.g., Y = 2) may be supported for multi-panel UL transmission. Note that the values ​​of X and Y are not limited to these. In multi-panel UL transmission, if UL precoding instructions for PUSCH are supported, a codebook of an existing system (e.g., Rel. 16 or earlier) may be supported for simultaneous multi-panel transmission. Considering single DCI and multi-DCI-based multi-TRP operation, the number of layers may be up to x (e.g., x = 4) in all panels, and the number of codewords (CWs) may be up to y (e.g., y = 2) in all panels. Note that the values ​​of x and y are not limited to these.

[0016] At least one of the following methods 1 to 3 (multi-panel UL transmission methods 1 to 3) is being considered as a multi-panel UL transmission method or a candidate multi-panel UL transmission method. Only one of transmission methods 1 to 3 may be supported. Multiple methods including at least one of transmission methods 1 to 3 may be supported, and one of the multiple transmission methods may be configured in the UE.

[0017] <Transmission Scheme 1: Coherent Multi-Panel UL Transmission> Multiple panels may be synchronized with each other. All layers are mapped to all panels. Multiple analog beams are directed. The SRS Resource Indicator (SRI) field may be extended. This scheme may use up to 4 layers for UL.

[0018] In the example of Figure 2A, the UE maps one codeword (CW) or one transport block (TB) to L layers (PUSCH (1, 2, ..., L)) and transmits the L layers from each of two panels. Panels #1 and #2 are coherent. Transmission scheme 1 can obtain diversity gain. The total number of layers in the two panels is 2L. If the maximum total number of layers is 4, the maximum number of layers in one panel is 2.

[0019] <Transmission Scheme 2: Non-coherent Multi-Panel UL Transmission of One Codeword (CW) or Transport Block (TB)> The multiple panels may not be synchronized. Different layers are mapped to one CW or TB for different panels and PUSCHs from multiple panels. A layer corresponding to one CW or TB may be mapped to multiple panels. This transmission scheme may use up to four layers or up to eight layers for the UL. If up to eight layers are supported, this transmission scheme may support one CW or TB using up to eight layers.

[0020] In the example of FIG. 2B, the UE maps 1 CW or 1 TB to k layers (PUSCH(1, 2, ..., k)) and L-k layers (PUSCH(k+1, k+2, ..., L)), transmits k layers from panel #1, and transmits L-k layers from panel #2. Transmission scheme 2 can obtain gains through multiplexing and diversity. The total number of layers in the two panels is L.

[0021] <Transmission Scheme 3: Non-coherent Multi-Panel UL Transmission of Two CWs or TBs> The multiple panels may not be synchronized. Different layers are mapped to different panels and two CWs or TBs for PUSCHs from the multiple panels. A layer corresponding to one CW or TB may be mapped to one panel. Layers corresponding to multiple CWs or TBs may be mapped to different panels. This transmission scheme may use up to four layers or up to eight layers for the UL. When up to eight layers are supported, this transmission scheme may support up to four layers per CW or TB.

[0022] In the example of FIG. 2C , the UE maps CW#1 or TB#1 of the 2CWs or 2TBs to k layers (PUSCH (1, 2, ..., k)), maps CW#2 or TB#2 to L-k layers (PUSCH (k+1, k+2, ..., L)), and transmits k layers from panel #1 and L-k layers from panel #2. Transmission scheme 3 can obtain gains through multiplexing and diversity. The total number of layers in the two panels is L.

[0023] In each of the above transmission schemes, the base station may configure or indicate panel-specific transmission for UL transmission using UL TCI or panel ID. UL TCI (UL TCI state) may be based on signaling similar to DL beam indication supported in Rel. 15. The panel ID may be implicitly or explicitly applied to transmission of at least one of the target RS resource or target RS resource set, PUCCH, SRS, and PRACH. When the panel ID is explicitly signaled, the panel ID may be configured in at least one of the target RS, target channel, and reference RS (e.g., DL RS resource configuration or spatial relationship information).

[0024] (Simultaneous Multi-Panel Transmission) In Rel. 18 and later, in one or more of the above-mentioned transmission schemes / modes, multi-panel UL transmission (e.g., simultaneous transmission across multiple panels (STxMP)) for PUSCH scheduling based on one DCI (single DCI) / PUSCH scheduling based on multiple DCIs (multi-DCI) is being considered.

[0025] For example, in Rel. 18, the following STxMPs are expected to be supported: Single DCI PUSCH SDM scheme, Single DCI PUSCH SFN scheme, Single DCI PUCCH SFN scheme, Multi-DCI overlapping PUSCH+PUSCH scheme.

[0026] <Single DCI-based STxMP> In Rel. 18 and later, a UE with multiple panels (e.g., Panel #1 and Panel #2) may support simultaneous multi-panel transmission (STxMP) in a single DCI-based multi-TRP system (see Figure 3A). In single DCI-based STxMP, the following schemes may be applied for UL transmission (e.g., PUSCH, PUCCH, or PUSCH+PUCCH).

[0027] Space Division Multiplexing (SDM) scheme (PUSCH): Different layers / DMRS ports of one PUSCH are separately precoded and transmitted simultaneously from different UE panels / beams (see Fig. 3B). Single Frequency Network (SFN)-based transmission scheme (PUSCH): All layers / DMRS ports of one PUSCH are transmitted simultaneously from two different UE panels / beams (see Fig. 3C). Single Frequency Network (SFN)-based transmission scheme (PUCCH): One PUCCH is transmitted simultaneously from different panels (see Fig. 3D).

[0028] Figure 3B shows an example of a case where the SDM scheme for a single DCI-based PUSCH is applied. The UE may assume that repeated SDM PUSCH transmissions are scheduled on the same time and frequency resources. That is, when using coherent panels, the UE may transmit repeated SDM PUSCH transmissions on the same time and frequency resources. Figure 3B shows a case where the time and frequency resources of Layer #1 and Layer #2 corresponding to the PUSCH are the same.

[0029] 3B may be applied to a case where SDM is applied to one CW (or TB), or may be applied to a case where SDM is applied to two CWs (or TBs). When SDM is applied to two CWs, two CWs simultaneously transmitted from two different panels are spatially multiplexed.

[0030] Figure 3C illustrates an example of a single DCI-based PUSCH SFN-based transmission scheme. In SFN, a UE transmits the same signal from panels corresponding to different TCI states (e.g., joint / UL TCI states) to the same RE. Here, all layers (e.g., Layers 1-2) / DMRS ports of one PUSCH are simultaneously transmitted from two different UE panels (e.g., Panel 1 and Panel 2).

[0031] 3D shows an example of a single DCI-based PUCCH SFN-based transmission scheme, in which one PUCCH is simultaneously transmitted from different panels (e.g., panel #1 and panel #2).

[0032] In the SDM / SFN scheme of a single DCI-based PUSCH, multiple (e.g., two) SRS resource sets may be configured and multiple (e.g., two) SRI / TPMI fields may be indicated.

[0033] In the SFN scheme for single DCI-based PUCCH, multiple (eg, two) TCI states may be applied to one PUCCH resource.

[0034] <Multi-DCI-Based STxMP> In Rel. 18 and later, a UE with multiple panels (e.g., Panel #1 and Panel #2) may support simultaneous multi-panel transmission (STxMP) in a multi-DCI-based multi-TRP system (see Figure 4A). In multi-DCI-based STxMP, simultaneous transmission of UL channels / UL signals (e.g., PUSCH+PUSCH) may be supported (see Figure 4B). For example, two overlapping PUSCHs in the time domain are associated with different TRPs and transmitted simultaneously from different UE panels / beams.

[0035] A UE may simultaneously transmit two independent PUSCHs associated with different TRPs in the same active BWP. The total number of layers corresponding to the two independent PUSCHs may be specified as a maximum of X (or less than or equal to X), where X may be, for example, 4 or some other value. The maximum number of layers for each of the two PUSCHs may be X / 2 (e.g., 2) or some other value. The two independent PUSCHs may also be associated with different CORESET pool indices.

[0036] In a multi-DCI-based PUSCH+PUSCH, multiple (e.g., two) SRS resource sets may be configured, and the two SRS resource sets may be associated with different (e.g., two) CORESET pool indices, respectively.

[0037] In Rel. 18, simultaneous transmission of PUSCHs (e.g., PUSCH+PUSCH scheme) is supported as multi-DCI-based STxMP. Furthermore, in Rel. 19 and later, simultaneous transmission including an uplink control channel (e.g., PUCCH) (e.g., STxMP PUCCH+PUCCH, STxMP PUCCH+PUSCH) is also expected to be supported as multi-DCI-based STxMP.

[0038] FIG. 5A shows an example of multi-DCI-based STxMP PUSCH+PUSCH, FIG. 5B shows an example of multi-DCI-based STxMP PUCCH+PUCCH, and FIG. 5C shows an example of multi-DCI-based STxMP PUCCH+PUSCH.

[0039] In STxMP PUSCH+PUSCH (see FIG. 5A), two PUSCHs are associated with different TRPs and transmitted simultaneously from a UE panel. The two PUSCHs may be partially / fully overlapping in the time domain or partially / fully / non-overlapping in the frequency domain. TRP may be replaced with panel, CORESET pool index, SRS resource set, SSB group, CSI-RS group, TCI state, or group of TCI states.

[0040] In STxMP PUCCH+PUCCH (see Fig. 5B), two PUCCHs are associated with different TRPs and transmitted simultaneously from the UE panel, and the two PUCCHs may be partially / fully overlapping in the time domain and partially / fully / non-overlapping in the frequency domain.

[0041] In STxMP PUCCH+PUSCH (see FIG. 5C), one PUCCH and one PUSCH are associated with different TRPs and transmitted simultaneously from the UE panel, and the PUCCH and PUSCH may be partially / fully overlapping in the time domain and partially / fully / non-overlapping in the frequency domain.

[0042] Prior to Rel. 17 (e.g., STxMP PUCCH+PUCCH in FIG. 5B and STxMP PUCCH+PUSCH in FIG. 5C are not supported), UE operations to resolve overlap between PUCCH and other UL channels / signals (e.g., PUCCH-PUCCH, PUCCH-PUSCH) were supported.

[0043] For example, when the PUCCH overlaps with other UL channels / signals, the UE multiplexes UCIs of multiple PUCCH transmissions into one PUCCH resource, multiplexes UCIs of PUCCH transmissions into PUSCH transmissions, or drops the PUCCH / PUSCH transmissions. The UL channel on which UCI is multiplexed / dropped may be determined based on predetermined criteria (e.g., UCI type, priority index of PUCCH / PUSCH, etc.).

[0044] In the case of overlap between PUCCH and other UL channels / signals, UE operation in legacy systems (e.g., pre-Rel. 17) is such that only one PUCCH or PUSCH is transmitted at a time after resolving the overlap between UL channels / signals.

[0045] In future wireless communication systems, when STxMP PUCCH+PUCCH / STxMP PUCCH+PUSCH are supported, it is also assumed that UE operation for overlapping transmission of PUCCHs and overlapping transmission of PUCCH and PUSCH will be supported / extended.

[0046] However, in multi-DCI-based STxMP, when overlapped transmission of PUCCH and UL channels / signals is supported, sufficient consideration has not been given to how UEs should operate, and if the UEs do not operate appropriately, communication quality may be degraded.

[0047] Therefore, the present inventors have focused on the case where PUCCH is supported as multi-DCI-based STxMP, studied UE operations in such a case, and conceived the present embodiment. Note that the present embodiment may be applied to systems other than STxMP with PUCCH.

In other words, at least one of N and M may be a number greater than 2.

[0076] (Wireless Communication Method) In the following description, a multi-DCI-based multi-TRP is taken as an example, but the application of this embodiment is not limited to this. It may also be applied to cases where UL channels / signals overlap in the time domain.

[0077] When multi-DCI-based multi-TRP is configured / applied, the UE may be provided with no CORESET pool index for the first CORESET of the active DL BWP of the serving cell, or may be provided with a CORESET pool index of a first value (e.g., 0), and may be provided with a CORESET pool index of a second value (e.g., 1) for the second CORESET of the active DL BWP of the serving cell.

[0079] In the following description, the case where two TRPs are configured in one cell / CC (or two TRPs are associated with one cell / CC) will be described as an example, but the case to which this embodiment can be applied is not limited to this. The number of TRPs may be three or more. It may also be applied to the case where two TRPs corresponding to different cells are configured (or a TRP is associated with each of multiple (e.g., two) cells / CCs).

[0080] <First embodiment> The first embodiment relates to an example of UE operation when STxMP including at least an uplink control channel (e.g., PUCCH) is supported. In the first embodiment, UL channels to which simultaneous transmission is applied may have the same priority (e.g., priority index) or different priorities.

[0081] When STxMP using PUCCH (e.g., STxMP PUCCH+PUCCH / STxMP PUCCH+PUSCH) is configured / supported / applied, different UE operations may be configured / supported / applied based on predetermined conditions. In the following description, "configured," "supported," and "applied" may be interpreted as interchangeable. The predetermined conditions may be, for example, at least one of the feedback mode of a delivery acknowledgement signal (e.g., HARQ-ACK or ACK / NACK) (Condition 1-1) and the content included in UCI (e.g., whether or not HARQ-ACK is included in UCI) (Condition 1-2).

[0082] [STxMP PUCCH+PUCCH] When two PUCCH transmissions associated with two different TRPs / two different UE panels overlap in the time domain and the UE supports STxMP PUCCH+PUCCH / STxMP PUCCH+PUCCH is configured (or enabled) for the UE by higher layer parameters, different UE behaviors may be applied based on predetermined conditions (e.g., condition 1-1 / condition 1-2).

[0083] When STxMP PUCCH+PUCCH is configured, a CORESET pool index / TRP index / panel index may be associated with each PUCCH (or PUCCH resource), respectively. For example, each PUCCH resource configured in the UE may be associated with either a first CORESET pool index / TRP index / panel index or a second CORESET pool index / TRP index / panel index.

[0084] In other words, one of the first PUCCH resource and the second PUCCH resource configured in the UE may be associated with a first CORESET pool index / TRP index / panel index, and the other may be associated with a second CORESET pool index / TRP index / panel index. In the present disclosure, PUCCH and PUCCH resource may be interchangeable.

[0085] <Condition 1-1> For simultaneous PUCCH transmission, different UE operations may be applied based on the feedback mode of the delivery acknowledgement signal. The feedback mode of the delivery acknowledgement signal may be configured in the UE by a higher layer parameter (e.g., ackNackFeedbackMode). For example, different (or different) UE operations may be applied when a first feedback mode (e.g., joint, or ackNackFeedbackMode=joint) is provided and when a second feedback mode (e.g., separate, or ackNackFeedbackMode=separate) is provided.

[0086] The UE may apply a first UE behavior when the first feedback mode is configured, and may apply a second UE behavior when the second feedback mode is configured.

[0087] First UE Operation: If a first feedback mode (e.g., joint) is provided / configured for the UE, UCIs of two PUCCHs (or PUCCH resources) associated with different TRP / panel / CORESET pool indices may be multiplexed and transmitted on one PUCCH (or PUCCH resource) (see Figure 6A).

[0088] FIG. 6A shows a case where PUCCH #1 and PUCCH #2 are associated with different TRP / panel / CORESET pool indices, and UCI #1 corresponding to PUCCH #1 and UCI #2 corresponding to PUCCH #2 are multiplexed onto a specific PUCCH (e.g., PUCCH #1 or PUCCH #2) and transmitted.

[0089] A specific PUCCH (or PUCCH resource) on which UCI is multiplexed / transmitted may be determined based on a predetermined rule. The predetermined rule may be a UCI type, a priority index, a panel index, or a TRP index. Alternatively, the predetermined rule may be a rule supported in Rel. 18.

[0090] In this way, when the feedback mode is set to joint, the UE may transmit UCI (e.g., HARQ-ACK) associated with each different TRP / panel / CORESET pool index on a specific PUCCH. Joint HARQ-ACK is expected to be suitable for an ideal backhaul case. Therefore, when the feedback mode is joint, UCI may be multiplexed and transmitted on a PUCCH corresponding to any TRP / panel.

[0091] Furthermore, in the first UE operation, a PUCCH that is not multiplexed with UCI may be transmitted or may be controlled not to be transmitted (for example, dropped). When UCI is transmitted on only one PUCCH (for example, by dropping another PUCCH or dropping a part (for example, an overlapping part) of another PUCCH), it is possible to increase the transmission power of the PUCCH transmission compared to when simultaneous PUCCH transmission (two PUCCH transmission) is performed.

[0092] Alternatively, HARQ-ACKs corresponding to two PUCCHs may be multiplexed onto a specific PUCCH, and the remaining UCI (e.g., CSI) other than the HARQ-ACKs corresponding to the other PUCCHs may be multiplexed onto the other PUCCHs and transmitted.

[0093] [Second UE Operation] When a second feedback mode (e.g., separate) is provided / configured for the UE, the UCI of two PUCCHs (or PUCCH resources) associated with different TRP / panel / CORESET pool indices may be transmitted simultaneously (or in overlapping time regions) on two PUCCH resources instead of being multiplexed onto one PUCCH (or PUCCH resource) (see Figure 6B).

[0094] FIG. 6B shows a case where PUCCH #1 and PUCCH #2 are associated with different TRP / panel / CORESET pool indices, and PUCCH #1 having UCI #1 and PUCCH #2 having UCI #2 are transmitted simultaneously.

[0095] For example, UCI corresponding to the first TRP / panel / CORESET pool index may be transmitted on a PUCCH corresponding to the first TRP / panel / first CORESET pool index, and UCI corresponding to the second TRP / panel / second CORESET pool index may be transmitted on a PUCCH corresponding to the second TRP / panel / second CORESET pool index.

[0096] Separate HARQ-ACK is expected to be preferably applied in a non-ideal backhaul case (e.g., a non-ideal backhaul case). For this reason, it is preferable that UCI is transmitted on the corresponding PUCCH (or transmitted on each of two simultaneously transmitted PUCCHs). The second UE operation enables each UCI to be directly fed back to the corresponding TRP. Note that the second UE operation may also be applied in an ideal backhaul case.

[0097] <Condition 1-2> For simultaneous PUCCH transmission, different UE operations may be applied based on the content included in the UCI. The content included in the UCI may be whether or not the UCI includes HARQ-ACK. For example, different (or different) UE operations may be applied when the UCI includes HARQ-ACK and when the UCI does not include HARQ-ACK.

[0098] The UE may apply a first UE behavior when the UCI does not include a HARQ-ACK, and may apply a second UE behavior when the UCI includes a HARQ-ACK.

[0099] The case where the UCI does not include HARQ-ACK may mean that none of the UCIs corresponding to each PUCCH include HARQ-ACK. The case where the UCI includes HARQ-ACK may mean that at least one of the UCIs corresponding to each PUCCH includes HARQ-ACK.

[0100] [First UE Operation] If the UCI does not include HARQ-ACK, the UCI of two PUCCHs (or PUCCH resources) associated with different TRP / panel / CORESET pool indices may be multiplexed and transmitted in one PUCCH (or PUCCH resource) (see Figure 7A).

[0101] FIG. 7A shows a case where PUCCH #1 and PUCCH #2 are associated with different TRP / panel / CORESET pool indices, and UCI #1 corresponding to PUCCH #1 and UCI #2 corresponding to PUCCH #2 are multiplexed onto a specific PUCCH (e.g., PUCCH #1 or PUCCH #2) and transmitted.

[0102] The PUCCH resource on which the UCI is multiplexed / transmitted may be determined based on a predetermined rule. The predetermined rule may be a UCI type, a priority index, a panel index, or a TRP index. Alternatively, the predetermined rule may be a rule supported in Rel. 18.

[0103] In this way, if the UCI (e.g., UCI #1 and UCI #2 in FIG. 7A) does not include HARQ-ACK, the UE may transmit UCI (e.g., HARQ-ACK) associated with different TRP / panel / CORESET pool indices, respectively, on a specific PUCCH.

[0104] In the first UE operation, a PUCCH that is not multiplexed with UCI may be transmitted or may be controlled not to be transmitted (e.g., dropped). When UCI is transmitted on only one PUCCH (e.g., by dropping other PUCCHs or dropping parts (e.g., overlapping parts) of other PUCCHs), it is possible to increase the transmission power of PUCCH transmission compared to when simultaneous PUCCH transmission (two PUCCH transmissions) is performed.

[0105] [Second UE Operation] If the UCI includes HARQ-ACK, the UCI of two PUCCHs (or PUCCH resources) associated with different TRP / panel / CORESET pool indices may be transmitted simultaneously (or in overlapping time regions) on two PUCCH resources instead of being multiplexed onto one PUCCH (or PUCCH resource) (see Figure 7B).

[0106] 7B shows a case where PUCCH #1 and PUCCH #2 are associated with different TRP / panel / CORESET pool indexes, and PUCCH #1 having UCI #1 and PUCCH # having UCI #2 are simultaneously transmitted. 7B shows a case where HARQ-ACK is included in both UCI #1 corresponding to PUCCH #1 and UCI #2 corresponding to PUCCH #2.

[0107] For example, UCI corresponding to a first TRP / panel / CORESET pool index may be transmitted on a PUCCH corresponding to the first TRP / panel / CORESET pool index, and UCI corresponding to a second TRP / panel / CORESET pool index may be transmitted on a PUCCH corresponding to the second TRP / panel / CORESET pool index.

[0108] Since the HARQ-ACK information is TRP-specific, when the UCI includes the HARQ-ACK, it is desirable to feed back the HARQ-ACK to the target TRP (or the corresponding TRP), at least in the non-ideal backhaul case. A second UE operation allows each HARQ-ACK (or UCI with the HARQ-ACK) to be fed back directly to the corresponding TRP.

[0109] On the other hand, compared to HARQ-ACK, for other UCI (for example, CSI / SR, etc.), it does not matter which TRP it is transmitted to, so UCI that does not include HARQ-ACK may be multiplexed and transmitted on a PUCCH corresponding to any TRP / panel. This allows UCI transmission using one PUCCH resource.

[0110] Condition 1-1 and Condition 1-2 may be considered separately, alone, or in combination. For example, different UE behaviors may be applied when both Condition 1-1 and Condition 1-2 are satisfied, or different UE behaviors may be applied when at least one of Condition 1-1 and Condition 1-2 is satisfied.

[0111] For example, a first UE behavior may be applied when a first feedback mode (e.g., joint) is provided / configured to the UE or when the UCI does not include HARQ-ACK, and a second UE behavior may be applied when a second feedback mode (e.g., separate) is provided / configured to the UE and the UCI includes HARQ-ACK.

[0112] - Variations In the above description, a first UE operation is applied when neither UCI #1 nor UCI #2 includes HARQ-ACK (see Figure 7A), and a second UE operation is applied when both UCI #1 and UCI #2 include HARQ-ACK (see Figure 7B), but this is not limited to this.

[0113] For example, when one of UCI #1 and UCI #2 includes HARQ-ACK and the other does not, a first UE operation or a second UE operation may be applied. For example, when the first UE operation is applied, UCI #1 and UCI #2 may be multiplexed and transmitted on a PUCCH corresponding to the UCI including HARQ-ACK. This allows the HARQ-ACK to be directly fed back to the corresponding TRP even when two UCIs are multiplexed on a specific PUCCH.

[0114] When one of UCI #1 and UCI #2 contains HARQ-ACK and the other does not, which of the first UE operation and the second UE operation is applied may be defined in the specification, may be set in the UE by the base station, or may be selected autonomously by the UE.

[0115] [STxMP PUCCH+PUSCH] When PUCCH transmissions and PUSCH transmissions associated with two different TRPs / two different UE panels overlap in the time domain and the UE supports STxMP PUCCH+PUSCH / STxMP PUCCH+PUSCH is configured (or enabled) by higher layer parameters, different UE behaviors may be supported / applied based on predetermined conditions (e.g., condition 1-1 / condition 1-2).

[0116] When STxMP PUCCH+PUSCH is configured, a CORESET pool index / TRP index / panel index may be associated with the PUCCH (or PUCCH resource) and the PUSCH, respectively. For example, the PUCCH and the PUSCH may be associated with either a first CORESET pool index / TRP index / panel index or a second CORESET pool index / TRP index / panel index.

[0117] In other words, one of the PUCCH and the PUSCH may be associated with a first CORESET pool index / TRP index / panel index, and the other may be associated with a second CORESET pool index / TRP index / panel index.

[0118] <Condition 1-1> For simultaneous PUCCH+PUSCH transmission, different UE operations may be applied based on the feedback mode of the delivery acknowledgement signal. The feedback mode of the delivery acknowledgement signal may be configured in the UE by a higher layer parameter (e.g., ackNackFeedbackMode). For example, different (or different) UE operations may be applied when a first feedback mode (e.g., joint, or ackNackFeedbackMode=joint) is provided and when a second feedback mode (e.g., separate, or ackNackFeedbackMode=separate) is provided.

[0119] The UE may apply a first UE behavior when the first feedback mode is configured, and may apply a second UE behavior when the second feedback mode is configured.

[0120] First UE Operation: If a first feedback mode (e.g., joint) is provided / configured for the UE, it may be supported / allowed that UCI of a PUCCH be multiplexed (and transmitted) on a PUSCH associated with a different TRP / panel / CORESET pool index than the PUCCH (see Figure 8A).

[0121] FIG. 8A shows a case where PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, and UCI corresponding to PUCCH is multiplexed onto PUSCH for transmission.

[0122] In this way, when the feedback mode is set to joint, the UE may transmit UCI (e.g., HARQ-ACK) corresponding to the PUCCH on the PUSCH. The joint HARQ-ACK is expected to be preferably applied in an ideal backhaul case. Therefore, when the feedback mode is joint, the UCI may be multiplexed onto the PUSCH (e.g., a PUSCH corresponding to a TRP different from the TRP of the PUCCH) and transmitted.

[0123] In the first UE operation, the PUCCH not multiplexed with UCI may be transmitted or may be controlled not to be transmitted (e.g., dropped). When UCI is transmitted on the PUSCH (e.g., dropping the PUCCH or dropping a part (e.g., overlapping part) of the PUCCH), it is possible to increase the transmission power of the PUSCH transmission compared to when simultaneous transmission of the PUCCH and the PUSCH is performed.

[0124] Alternatively, if the UCI of the PUCCH includes multiple UCI types (HARQ-ACK / SR / CSI-RS), some of the UCI types may be multiplexed onto the PUSCH, and the remaining UCI types may be multiplexed onto the PUCCH and transmitted.

[0125] [Second UE Operation] When a second feedback mode (e.g., separate) is provided / configured for the UE, the UCI of the PUCCH may not be multiplexed onto a PUSCH associated with a different TRP / panel from the PUCCH, but the PUCCH and PUSCH may be transmitted simultaneously (or in overlapping time domains) (see Figure 8B).

[0126] FIG. 8B shows a case where PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, and PUCCH and PUSCH having UCI are transmitted simultaneously.

[0127] For example, the UCI corresponding to the first TRP / panel / CORESET pool index may be multiplexed onto a PUCCH corresponding to the first TRP / panel / first CORESET pool index and transmitted, and the PUCCH and a PUSCH corresponding to the second TRP / panel / first CORESET pool index may be transmitted simultaneously.

[0128] Separate HARQ-ACK is expected to be preferably applied in a non-ideal backhaul case (e.g., a non-ideal backhaul case). For this reason, it is preferable that UCI is transmitted on the corresponding PUCCH (or that transmission on a PUSCH corresponding to a TRP different from the TRP of the PUCCH is not performed). The second UE operation enables UCI to be fed back directly to the corresponding TRP. Note that the second UE operation may also be applied in an ideal backhaul case.

[0129] <Condition 1-2> For simultaneous PUCCH+PUSCH transmission, different UE operations may be applied based on the content included in the UCI. The content included in the UCI may be, for example, whether or not the UCI includes HARQ-ACK. For example, different (or different) UE operations may be applied when the UCI includes HARQ-ACK and when the UCI does not include HARQ-ACK.

[0130] The UE may apply a first UE behavior when the UCI does not include a HARQ-ACK, and may apply a second UE behavior when the UCI includes a HARQ-ACK.

[0131] [First UE Operation] If the UCI does not include HARQ-ACK, it may be supported / allowed for the UCI of the PUCCH to be multiplexed (and transmitted) on a PUSCH associated with a different TRP / panel / CORESET pool index than the PUCCH (see Figure 9A).

[0132] FIG. 9A shows a case where PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, and UCI corresponding to PUCCH is multiplexed onto PUSCH for transmission.

[0133] In the first UE operation, the PUCCH not multiplexed with UCI may be transmitted or may be controlled not to be transmitted (e.g., dropped). When UCI is transmitted on the PUSCH (e.g., dropping the PUCCH or dropping a part (e.g., overlapping part) of the PUCCH), it is possible to increase the transmission power of the PUSCH transmission compared to when simultaneous transmission of the PUCCH and the PUSCH is performed.

[0134] [Second UE Operation] If the UCI includes HARQ-ACK, the UCI of the PUCCH may be transmitted simultaneously (or in overlapping time regions) with the PUSCH, rather than being multiplexed onto a PUSCH associated with a different TRP / panel / CORESET pool index than the PUCCH.

[0135] For example, the UCI corresponding to the first TRP / panel / CORESET pool index may be transmitted on a PUCCH corresponding to the first TRP / panel / CORESET pool index, and the PUCCH and a PUSCH corresponding to the second TRP / panel / first CORESET pool index may be transmitted simultaneously (see Figure 9B).

[0136] FIG. 9B shows a case where PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, and PUCCH and PUSCH having UCI are transmitted simultaneously.

[0137] Since the HARQ-ACK information is TRP-specific, when the UCI includes the HARQ-ACK, it is desirable to feed back the HARQ-ACK to the target TRP (or the corresponding TRP), at least in the non-ideal backhaul case. A second UE operation allows each HARQ-ACK (or UCI with the HARQ-ACK) to be fed back directly to the corresponding TRP.

[0138] On the other hand, compared to HARQ-ACK, for other UCI (e.g., CSI / SR, etc.), it does not matter which TRP it is transmitted on, so UCI that does not include HARQ-ACK may be multiplexed and transmitted on a PUSH corresponding to a TRP different from the TRP of the PUCH.

[0139] Condition 1-1 and Condition 1-2 may be considered separately, alone, or in combination. For example, different UE behaviors may be applied when both Condition 1-1 and Condition 1-2 are satisfied, or different UE behaviors may be applied when at least one of Condition 1-1 and Condition 1-2 is satisfied.

[0140] For example, a first UE behavior may be applied when a first feedback mode (e.g., joint) is provided / configured to the UE or when the UCI does not include HARQ-ACK, and a second UE behavior may be applied when a second feedback mode (e.g., separate) is provided / configured to the UE and the UCI includes HARQ-ACK.

[0141] Second Embodiment The second embodiment relates to another example of UE operation when STxMP including at least an uplink control channel (e.g., PUCCH) is supported. In the second embodiment, UL channels to which simultaneous transmission is applied may have the same priority (e.g., priority index) or different priorities. The second embodiment may be applied alone or in combination with other embodiments.

[0142] When STxMP using PUCCH (e.g., STxMP PUCCH+PUCCH / STxMP PUCCH+PUSCH) is configured, UE operation may be controlled based on whether PUCCH / PUSCH dropping is applied and at least one of the TRP / panel / CORESET pool indexes corresponding to the first UL transmission (e.g., PUCCH) and the second UL transmission (e.g., PUCCH or PUSCH) transmitted simultaneously.

[0143] [STxMP PUCCH+PUCCH] If the UE supports STxMP PUCCH+PUCCH / STxMP PUCCH+PUCCH is configured (or enabled) for the UE by higher layer parameters, and two PUCCH transmissions overlap in the time domain, at least one of the following Option 2-1 to Option 2-2 may be applied.

[0144] <<Option 2-1>> When a rule (e.g., a first rule) is defined / configured in which one of two PUCCHs that overlap in the time domain (or a part of one of the PUCCHs (e.g., the overlapping part)) is dropped, the following UE operations may be supported.

[0145] If two PUCCH transmissions are associated with the same TRP / panel / CORESET pool index, the first rule may be applied. That is, the UE may control to drop one of the two PUCCHs (or a part of one of the PUCCHs). The PUCCH to be dropped may be determined based on a predetermined rule. The predetermined rule may be a UCI type / priority index / panel index / TRP index. Alternatively, the predetermined rule may be a rule supported by Rel. 18.

[0146] If two PUCCH transmissions are associated with different TRP / panel / CORESET pool indices, the following options 2-1-1 to 2-1-2 may apply.

[0147] Option 2-1-1 The first rule may be applied. That is, the UE may be controlled to drop one of the two PUCCHs (or a part of one of the PUCCHs). When option 2-1-1 is applied, the same UE operation (e.g., dropping one of the PUCCHs) is applied regardless of the TRP / panel / CORESET pool index associated with each PUCCH. This can simplify the UE operation.

[0148] Option 2-1-2: Two PUCCHs may be transmitted simultaneously. In other words, the UE may perform control so as to transmit two PUCCHs simultaneously without dropping any PUCCHs.

[0149] When Option 2-1-2 is applied, different UE behavior (e.g., dropping one PUCCH or transmitting PUCCHs simultaneously) may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the two PUCCHs are the same or not. In this case, UCI (e.g., HARQ-ACK) can be fed back directly for multiple TRPs.

[0150] <<Option 2-2>> When the UCIs of two PUCCHs that overlap in the time domain are multiplexed and a rule (e.g., a second rule) is defined / configured such that the PUCCHs (or a portion of the PUCCHs (e.g., the overlapping portion)) are not dropped, the following UE operations may be supported.

[0151] If two PUCCH transmissions are associated with the same TRP / panel / CORESET pool index, a second rule may be applied. That is, the UE may multiplex UCIs of two PUCCHs onto a PUCCH (e.g., a specific PUCCH) and transmit the multiplexed UCIs. The specific PUCCH onto which the UCIs are multiplexed may be determined based on a predetermined rule. The predetermined rule may be a UCI type, a priority index, a panel index, or a TRP index. Alternatively, the predetermined rule may be a rule supported by Rel. 18.

[0152] If two PUCCH transmissions are associated with different TRP / panel / CORESET pool indices, the following options 2-2-1 to 2-2-2 may apply.

[0153] Option 2-2-1 The second rule may be applied, that is, the UE may multiplex UCI of two PUCCHs onto a PUCCH (e.g., a specific PUCCH) and transmit the multiplexed UCI.

[0154] Option 2-2-1 may be applied when the HARQ-ACK feedback mode is set to joint (e.g., ackNackFeedbackMode=joint) or when the UCI does not include HARQ-ACK.

[0155] Option 2-2-2: Two PUCCHs may be transmitted simultaneously. That is, the UE may perform control so that UCI corresponding to each PUCCH is transmitted using the corresponding PUCCH (two PUCCHs are transmitted simultaneously). Option 2-2-2 may be applied when separate (e.g., ackNackFeedbackMode=separate) is set as the HARQ-ACK feedback mode and HARQ-ACK is included in the UCI.

[0156] [STxMP PUCCH+PUSCH] If the UE supports STxMP PUCCH+PUSCH / STxMP PUCCH+PUSCH is configured (or enabled) for the UE by higher layer parameters, and PUCCH transmission and PUSCH transmission overlap in the time domain, at least one of the following options 2-3 to 2-4 may be applied.

[0157] <<Option 2-3>> When a rule (e.g., a third rule) is defined / configured to drop the PUCCH (or a portion of the PUCCH (e.g., the overlapping portion)) or the PUSCH (or a portion of the PUSCH (e.g., the overlapping portion)) of the PUCCH and PUSCH that overlap in the time domain, the following UE operations may be supported.

[0158] When PUCCH transmission and PUSCH transmission are associated with the same TRP / panel / CORESET pool index, a third rule may be applied. That is, the UE may control to drop one of the PUCCH and PUSCH (or a part of one of the PUCCH and PUSCH). The UL channel (e.g., PUCCH or PUSCH) to be dropped may be determined based on a predetermined rule. The predetermined rule may be a UCI type / priority index / panel index / TRP index. Alternatively, the predetermined rule may be a rule supported by Rel. 18.

[0159] If PUCCH transmission and PUSCH transmission are associated with different TRP / panel / CORESET pool indices, the following options 2-3-1 to 2-3-2 may apply.

[0160] Option 2-3-1 The third rule may be applied. That is, the UE may be controlled to drop one of the PUCCH and the PUSCH (or a part of one of the PUCCH and the PUSCH). When option 2-3-1 is applied, the same UE operation (e.g., dropping one of the PUCCHs) is applied regardless of the TRP / panel / CORESET pool index associated with each PUCCH. This can simplify the UE operation.

[0161] Option 2-3-2: PUCCH and PUSCH may be transmitted simultaneously. In other words, the UE may perform control so that PUCCH and PUSCH are transmitted simultaneously without dropping PUCCH or PUSCH.

[0162] When Option 2-3-2 is applied, different UE behaviors (e.g., dropping one PUCCH or simultaneously transmitting PUCCH) may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same or not. In this case, UCI (e.g., HARQ-ACK) corresponding to each TRP can be fed back directly to that TRP.

[0163] <<Option 2-4>> When a rule (e.g., the fourth rule) is defined / configured such that UCI is multiplexed onto PUSCH and PUCCH / PUSCH (or a part of PUCCH / PUSCH (e.g., an overlapping part)) is not dropped, the following UE operations may be supported.

[0164] If the PUCCH transmission and the PUSCH transmission are associated with the same TRP / panel / CORESET pool index, the fourth rule may apply, i.e., the UE may multiplex the UCI of the PUCCH onto the PUSCH for transmission.

[0165] If PUCCH transmission and PUSCH transmission are associated with different TRP / panel / CORESET pool indices, the following options 2-4-1 to 2-4-2 may apply.

[0166] Option 2-4-1 The fourth rule may be applied. That is, the UE may multiplex the UCI of the PUCCH onto the PUSCH and transmit the multiplexed UCI. Option 2-4-1 may be applied when the HARQ-ACK feedback mode is set to joint (e.g., ackNackFeedbackMode=joint) or when the UCI does not include HARQ-ACK.

[0167] Option 2-4-2: The PUCCH and the PUSCH may be transmitted simultaneously. That is, the UE may transmit UCI corresponding to the PUCCH on the PUCCH and control the simultaneous transmission of the PUCCH and the PUSCH. Option 2-4-2 may be applied when separate (e.g., ackNackFeedbackMode=separate) is set as the HARQ-ACK feedback mode and the UCI includes HARQ-ACK.

[0168] Third Embodiment The third embodiment relates to UE operation based on the priority of simultaneously transmitted UL channels (e.g., STxMP PUCCH+PUCCH). The third embodiment may be applied alone or in combination with other embodiments.

[0169] The UE may be configured with an upper layer parameter (e.g., uci-MuxWithDiffPrio) related to multiplexing UCI (e.g., HARQ-ACK) of different priorities. When the upper layer parameter is configured / enabled, multiplexing UCI (e.g., HARQ-ACK) of a first priority (e.g., high priority (HP)) and UCI (e.g., HARQ-ACK) of a second priority (e.g., low priority (LP)) lower than the first priority onto the PUCCH / PUSCH may be enabled for the primary PUCCH group and the secondary PUCCH group.

[0170] For example, when the higher layer parameter (e.g., uci-MuxWithDiffPrio) is configured and a PUCCH with a first priority (hereinafter also referred to as HP-PUCCH) and a PUCCH with a second priority (hereinafter also referred to as LP-PUCCH) overlap in the time domain, the following UE operation #3 (or multiplexing method) may be supported / applied.

[0171] [UE Operation #3 / Multiplexing Method] For "LP-PUCCH having only HARQ-ACK information" and "HP-PUCCH having only HARQ-ACK information", the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource.

[0172] For "LP-PUCCH having only HARQ-ACK information" and "HP-PUCCH having HARQ-ACK and SR", the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource.

[0173] For "LP-PUCCH having HARQ-ACK and CSI / SR" and "HP-PUCCH having only HARQ-ACK information", the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH.

[0174] For "LP-PUCCH having HARQ-ACK and CSI / SR" and "HP-PUCCH having HARQ-ACK and SR", the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH.

[0175] In UE operation #3, the PUCCH with HARQ-ACK (e.g., LP-PUCCH / HP-PUCCH) may be a PUCCH without repetition. The LP-PUCCH may be a PUCCH with LP-HARQ. The HP-PUCCH may be a PUCCH with HP-HARQ (or HP-HARQ / SR).

[0176] [STxMP PUCCH+PUCCH] When a UE supports STxMP PUCCH+PUCCH / STxMP PUCCH+PUCCH is configured (or enabled) in the UE by higher layer parameters, multiplexing of UCI with different priorities (e.g., HARQ-ACK, etc.) is enabled for PUCCH, and two PUCCH transmissions with different priorities overlap in the time domain, the UE operation to be applied may be determined based on predetermined conditions.

[0177] The UE operation to be applied may be determined based on at least one of the following: the TRP / panel / CORESET pool index corresponding to each PUCCH (e.g., whether the TRP corresponds to the same TRP or different TRPs), the content of the UCI of the HP-PUCCH, and the content of the LP-PUCCH. For example, when two PUCCH transmissions with different priorities (e.g., the LP-PUCCH and the HP-PUCCH) overlap in the time domain, at least one of the following cases 3-1 to 3-4 may be supported / applied.

[0178] <<Case 3-1>> The following UE operations may be applied to the "LP-PUCCH having only HARQ-ACK information" and the "HP-PUCCH having only HARQ-ACK information."

[0179] If two PUCCHs are associated with the same TRP / panel / CORESET pool index, then UE action #3 above may apply, e.g., the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource.

[0180] If two PUCCHs are associated with different TRP / panel / CORESET pool indices, at least one of Option 3-1-1 to Option 3-1-2 may be applied.

[0181] Option 3-1-1: The UE operation #3 described above may be applied. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource (see FIG. 10A). In FIG. 10A, the LP-PUCCH and the HP-PUCCH are associated with different TRP / panel / CORESET pool indices, and the HARQ-ACK #1 (UCI #1) of the LP-PUCCH and the HARQ-ACK #2 (UCI #2) of the HP-PUCCH are multiplexed onto the HP-PUCCH resource for transmission.

[0182] When Option 3-1-1 is applied, the same UE behavior applies regardless of the TRP / Panel / CORESET pool index associated with each PUCCH, which can simplify the UE behavior.

[0183] Option 3-1-2: Two PUCCHs may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH onto the LP-PUCCH resource and transmit the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource (see FIG. 10B). In FIG. 10B, the LP-PUCCH and the HP-PUCCH are associated with different TRP / panel / CORESET pool indices, and the LP-PUCCH with HARQ-ACK#1 (UCI#1) and the HP-PUCCH with HARQ-ACK#2 (UCI#2) are simultaneously transmitted.

[0184] When Option 3-1-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with two PUCCHs are the same or not, in which case simultaneous transmission of multiple PUCCHs corresponding to different TRPs allows direct feedback of each UCI (e.g., HARQ-ACK) to the corresponding TRP.

[0185] <<Case 3-2>> For the "LP-PUCCH having only HARQ-ACK information" and the "HP-PUCCH having HARQ-ACK and SR", the following UE operations may be applied.

[0186] If two PUCCHs are associated with the same TRP / panel / CORESET pool index, then UE action #3 above may apply, e.g., the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource.

[0187] If two PUCCHs are associated with different TRP / panel / CORESET pool indices, at least one of options 3-2-1 to 3-2-2 may be applied.

[0188] Option 3-2-1 The UE operation #3 described above may be applied. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource. When option 3-2-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool index associated with each PUCCH. This can simplify the UE operation.

[0189] Option 3-2-2: Two PUCCHs may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH onto the LP-PUCCH resource and transmit the HARQ-ACK and SR of the HP-PUCCH onto the HP-PUCCH resource. When Option 3-2-2 is applied, different UE operations may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the two PUCCHs are the same. In this case, simultaneous transmission of multiple PUCCHs corresponding to different TRPs allows each UCI (e.g., HARQ-ACK) to be directly fed back to the corresponding TRP.

[0190] <<Case 3-3>> The following UE operations may be applied to the “LP-PUCCH having HARQ-ACK and CSI / SR” and the “HP-PUCCH having only HARQ-ACK information”.

[0191] If two PUCCHs are associated with the same TRP / panel / CORESET pool index, UE action #3 above may apply. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource. Meanwhile, the UE may drop the CSI / SR of the LP-PUCCH.

[0192] If two PUCCHs are associated with different TRP / panel / CORESET pool indices, at least one of Option 3-3-1 to Option 3-3-2 may be applied.

[0193] Option 3-3-1 The above-described UE operation #3 may be applied. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH (see FIG. 11A). FIG. 11A illustrates a case where the LP-PUCCH and the HP-PUCCH are associated with different TRP / panel / CORESET pool indices, and the HARQ-ACK #1 (UCI #1) of the LP-PUCCH and the HARQ-ACK #2 (UCI #2) of the HP-PUCCH are multiplexed onto the PUSCH multiplexed onto the HP-PUCCH resource and transmitted, and the CSI / SR of the LP-PUCCH is dropped.

[0194] When Option 3-3-1 is applied, the same UE behavior applies regardless of the TRP / Panel / CORESET pool index associated with each PUCCH, which can simplify the UE behavior.

[0195] Option 3-3-2: Two PUCCHs may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK and CSI / SR of the LP-PUCCH onto the LP-PUCCH resource for transmission, and may multiplex the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource for transmission (see FIG. 11B). In FIG. 11B, the LP-PUCCH and the HP-PUCCH are associated with different TRP / panel / CORESET pool indices, and the LP-PUCCH having HARQ-ACK#1 (UCI#1) and CSI / SR and the HP-PUCCH having HARQ-ACK#2 (UCI#2) are simultaneously transmitted.

[0196] When Option 3-3-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with two PUCCHs are the same. In this case, simultaneous transmission of multiple PUCCHs corresponding to different TRPs allows direct feedback of each UCI (e.g., HARQ-ACK) to the corresponding TRP. Also, UCI (e.g., CSI / SR) other than the HARQ-ACK corresponding to the LP-PUCCH can be transmitted without dropping.

[0197] As a variation of Option 3-3-2, the UE may multiplex the HARQ-ACK of the LP-PUCCH and the HARQ-ACK of the HP-PUCCH onto the HP-PUCCH resource, and multiplex the remaining UCI (e.g., CSI / SR of the LP-PUCCH) onto the LP-PUCCH, and simultaneously transmit the LP-PUCCH and the HP-PUCCH. This UE operation may be applied when the HARQ-ACK feedback mode is joint.

[0198] <<Case 3-4>> For the “LP-PUCCH with HARQ-ACK and CSI / SR” and the “HP-PUCCH with HARQ-ACK and SR”, the following UE operations may be applied.

[0199] If two PUCCHs are associated with the same TRP / panel / CORESET pool index, UE action #3 described above may apply. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource. Meanwhile, the UE may drop the CSI / SR of the LP-PUCCH.

[0200] If two PUCCHs are associated with different TRP / panel / CORESET pool indices, at least one of options 3-4-1 to 3-4-2 may be applied.

[0201] Option 3-4-1 The above-mentioned UE operation #3 may be applied. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH. When option 3-4-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool index associated with each PUCCH. This can simplify the UE operation.

[0202] Option 3-4-2: Two PUCCHs may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK and CSI / SR of the LP-PUCCH onto the LP-PUCCH resource and transmit them, and may multiplex the HARQ-ACK and SR of the HP-PUCCH onto the HP-PUCCH resource and transmit them. When Option 3-4-2 is applied, different UE operations may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the two PUCCHs are the same. In this case, simultaneous transmission of multiple PUCCHs corresponding to different TRPs allows each UCI (e.g., HARQ-ACK) to be directly fed back to the corresponding TRP. Furthermore, it is possible to transmit UCI (e.g., CSI / SR) other than the HARQ-ACK corresponding to the LP-PUCCH without dropping it.

[0203] As a variation of Option 3-4-2, the UE may multiplex the HARQ-ACK of the LP-PUCCH, the HARQ-ACK of the HP-PUCCH, and the SR of the HP-PUCCH onto the HP-PUCCH resource, and multiplex the remaining UCI (e.g., CSI / SR of the LP-PUCCH) onto the LP-PUCCH, and simultaneously transmit the LP-PUCCH and the HP-PUCCH. This UE operation may be applied when the HARQ-ACK feedback mode is joint.

[0204] In at least one of Case 3-1 to Case 3-4, different options may be applied based on the feedback mode (e.g., ackNackFeedbackMode) provided / configured to the UE. For example, if the feedback mode is joint (e.g., ackNackFeedbackMode=joint), Options 3-1-1 / 3-2-1 / 3-3-1 / 3-4-1 may be applied. If the feedback mode is separate (e.g., ackNackFeedbackMode=separate), Options 3-1-2 / 3-2-2 / 3-3-2 / 3-4-2 may be applied.

[0205] <Fourth embodiment> The fourth embodiment relates to an example of UE operation based on the priority of simultaneously transmitted UL channels (e.g., STxMP PUCCH+PUSCH). The fourth embodiment may be applied alone or in combination with other embodiments.

[0206] The UE may be configured with higher layer parameters (eg, uci-MuxWithDiffPrio) related to multiplexing of UCIs with different priorities (eg, HARQ-ACKs).

[0207] For example, when the higher layer parameter (e.g., uci-MuxWithDiffPrio) is configured and a PUCCH with a second priority (hereinafter also referred to as LP-PUCCH) and a PUSCH with a first priority higher than the second priority (hereinafter also referred to as HP-PUSCH) overlap in the time domain, the following UE operation #4 (or multiplexing method) may be supported / applied.

[0208] [UE Operation #4 / Multiplexing Method] For "LP-PUCCH having only HARQ-ACK information" and "HP-PUSCH having no CSI or HP-PUSCH having single-part CSI", the UE may multiplex the HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH.

[0209] For "LP-PUCCH having HARQ-ACK and CSI / SR" and "HP-PUSCH without CSI or HP-PUSCH with single-part CSI", the UE may multiplex HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH. On the other hand, the UE may drop CSI / SR of the LP-PUCCH.

[0210] In UE operation #4, the PUCCH with HARQ-ACK (eg, LP-PUCCH) may be a PUCCH without repetition.

[0211] [STxMP PUCCH+PUSCH] When a UE supports STxMP PUCCH+PUSCH / STxMP PUCCH+PUSCH is configured (or enabled) in the UE by higher layer parameters, multiplexing of UCI with different priorities (e.g., HARQ-ACK, etc.) is enabled for PUCCH / PUSCH, and PUCCH transmission and PUSCH transmission with different priorities (e.g., LP-PUCCH and HP-PUSCH) overlap in the time domain, an applicable UE operation may be determined based on predetermined conditions.

[0212] The UE operation to be applied may be determined based on at least one of the following predetermined conditions: the TRP / panel / CORESET pool index corresponding to the PUCCH and the PUSCH (e.g., whether they correspond to the same TRP / different TRP), the content of the UCI of the LP-PUCCH, and the content of the UCI of the HP-PUSCH. For example, when PUCCH transmission and PUSCH transmission with different priorities (e.g., LP-PUCCH and HP-PUSCH) overlap in the time domain, at least one of the following Cases 4-1 to 4-2 may be supported / applied.

[0213] <<Case 4-1>> For the "LP-PUCCH having only HARQ-ACK information" and the "HP-PUSCH having no CSI or HP-PUSCH having single-part CSI", the following UE operations may be applied.

[0214] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #4 above may apply, e.g., the UE may multiplex HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH.

[0215] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of Option 4-1-1 to Option 4-1-2 may be applied.

[0216] Option 4-1-1: The UE operation #4 described above may be applied. For example, the UE may multiplex HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH (see FIG. 12A). In FIG. 12A, the LP-PUCCH and the HP-PUSCH are associated with different TRP / panel / CORESET pool indices, and the HARQ-ACK of the LP-PUCCH is multiplexed onto the HP-PUSCH for transmission.

[0217] When Option 4-1-1 is applied, the same UE behavior applies regardless of the TRP / Panel / CORESET pool index associated with the PUCCH and PUSCH, which can simplify the UE behavior.

[0218] Option 4-1-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK of the LP-PUCCH onto the LP-PUCCH resource and transmit the HP-PUSCH, which overlaps with the LP-PUCCH in the time domain (see FIG. 12B). FIG. 12B shows a case where the LP-PUCCH and the HP-PUSCH are associated with different TRP / panel / CORESET pool indices, and the LP-PUCCH and the HP-PUSCH with HARQ-ACK are simultaneously transmitted.

[0219] When option 4-1-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same or not.

[0220] Support for simultaneous transmission of LP-PUCCH and HP-PUSCH corresponding to different TRPs (or transmission of LP-PUCCH overlapping with HP-PUSCH) makes it possible to directly feed back the UCI of LP-PUCCH (e.g., HARQ-ACK) to the corresponding TRP.

[0221] <<Case 4-2>> The following UE operations may be applied to the “LP-PUCCH having HARQ-ACK and CSI / SR” and the “HP-PUSCH without CSI or HP-PUSCH with single-part CSI.”

[0222] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, the UE operation #4 described above may be applied. For example, the UE may multiplex the HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH.

[0223] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 4-2-1 to 4-2-2 may be applied.

[0224] Option 4-2-1 The above-mentioned UE operation #4 may be applied. For example, the UE may multiplex HARQ-ACK information of the LP-PUCCH onto the HP-PUSCH. On the other hand, the UE may drop the CSI / SR of the LP-PUCCH. When option 4-2-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH. This can simplify the UE operation.

[0225] Option 4-2-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex the HARQ-ACK and CSI / SR of the LP-PUCCH onto the LP-PUCCH resource and transmit the HP-PUSCH, which overlaps with the LP-PUCCH in the time domain. When Option 4-2-2 is applied, different UE operations may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and the PUSCH are the same.

[0226] Support for simultaneous transmission of LP-PUCCH and HP-PUSCH corresponding to different TRPs (or transmission of LP-PUCCH overlapping with HP-PUSCH) makes it possible to directly feed back the UCI of LP-PUCCH (e.g., HARQ-ACK) to the corresponding TRP.

[0227] As a variation of Option 4-2-2, the UE may multiplex the HARQ-ACK of the LP-PUCCH onto the HP-PUSCH and multiplex the remaining UCI (e.g., CSI / SR of the LP-PUCCH) onto the LP-PUCCH, and simultaneously transmit the LP-PUCCH and the HP-PUSCH. This UE operation may be applied when the HARQ-ACK feedback mode is joint.

[0228] In at least one of Case 4-1 and Case 4-2, different options may be applied based on the feedback mode (e.g., ackNackFeedbackMode) provided / configured to the UE. For example, if the feedback mode is joint (e.g., ackNackFeedbackMode=joint), option 4-1-1 / 4-2-1 may be applied. If the feedback mode is separate (e.g., ackNackFeedbackMode=separate), option 4-1-2 / 4-2-2 may be applied.

[0229] Fifth Embodiment The fifth embodiment relates to another example of UE operation based on the priority of simultaneously transmitted UL channels (e.g., STxMP PUCCH+PUSCH). The fifth embodiment may be applied alone or in combination with other embodiments.

[0230] The UE may be configured with higher layer parameters (eg, uci-MuxWithDiffPrio) related to multiplexing of UCIs with different priorities (eg, HARQ-ACKs).

[0231] For example, when the higher layer parameter (e.g., uci-MuxWithDiffPrio) is configured and a first priority PUCCH (hereinafter also referred to as HP-PUCCH) and a first priority PUSCH (hereinafter also referred to as HP-PUSCH) overlap in the time domain, the following UE operation #5 (or multiplexing method) may be supported / applied.

[0232] [UE Operation #5 / Multiplexing Method] When HARQ-ACK information having a second priority (hereinafter also referred to as LP-HARQ) lower than the first priority and HARQ-ACK information having a first priority (hereinafter also referred to as HP-HARQ) are transmitted by HP-PUCCH, and the HP-PUSCH has no CSI or has single-part CSI, the UE may multiplex the LP-HARQ and the HP-HARQ onto the HP-PUSCH.

[0233] When HARQ-ACK information having a second priority (hereinafter also referred to as LP-HARQ) lower than the first priority and HARQ-ACK information having a first priority (hereinafter also referred to as HP-HARQ) are transmitted by the HP-PUCCH, and the HP-PUSCH has a Part 1 CSI report and a Part 2 CSI report, the UE may multiplex the HP-HARQ onto the HP-PUSCH and transmit the multiplexed information. On the other hand, the UE may drop the LP-HARQ.

[0234] In UE action #5, the PUCCH with HARQ-ACK (eg, HP-PUCCH) may be a PUCCH without repetition.

[0235] [STxMP PUCCH+PUSCH] When a UE supports STxMP PUCCH+PUSCH / STxMP PUCCH+PUSCH is configured (or enabled) in the UE by higher layer parameters, multiplexing of UCI with different priorities (e.g., HARQ-ACK, etc.) is enabled for PUCCH / PUSCH, and PUCCH transmission and PUSCH transmission with the same priority (e.g., first priority) overlap in the time domain, an applicable UE operation may be determined based on a predetermined condition.

[0236] The UE operation to be applied may be determined based on at least one of the following predetermined conditions: the TRP / panel / CORESET pool index to which the PUCCH and the PUSCH correspond (e.g., whether they correspond to the same TRP / different TRP), the content of the UCI of the HP-PUCCH, and the content of the UCI of the HP-PUSCH. For example, when PUCCH transmission and PUSCH transmission with the same priority (e.g., HP-PUCCH and HP-PUSCH) overlap in the time domain, at least one of the following Cases 5-1 to 5-2 may be supported / applied.

[0237] <<Case 5-1>> When LP-HARQ and HP-HARQ are transmitted by HP-PUCCH, and HP-PUSCH has no CSI or single-part CSI, the following UE operation may be applied.

[0238] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #5 above may apply, e.g., the UE may multiplex LP-HARQ and HP-HARQ onto the HP-PUSCH.

[0239] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 5-1-1 to 5-1-2 may be applied.

[0240] Option 5-1-1: UE Operation #5 described above may be applied. For example, the UE may multiplex LP-HARQ and HP-HARQ onto the HP-PUSCH (see FIG. 13A). In FIG. 13A, the HP-PUCCH and HP-PUSCH are associated with different TRP / panel / CORESET pool indices, and the LP-HARQ and HP-HARQ are multiplexed onto the HP-PUSCH for transmission.

[0241] When Option 5-1-1 is applied, the same UE behavior applies regardless of the TRP / Panel / CORESET pool index associated with the PUCCH and PUSCH, which can simplify the UE behavior.

[0242] Option 5-1-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex LP-HARQ and HP-HARQ onto the HP-PUCCH resource and transmit the HP-PUSCH, which overlaps with the HP-PUCCH in the time domain (see FIG. 13B). FIG. 13B shows a case where the HP-PUCCH and HP-PUSCH are associated with different TRP / panel / CORESET pool indices, and the HP-PUCCH and HP-PUSCH with LP-HARQ and HP-HARQ are simultaneously transmitted.

[0243] When option 5-1-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same or not.

[0244] Support for simultaneous transmission of HP-PUCCH and HP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with HP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., LP-HARQ / HP-HARQ) to the corresponding TRP.

[0245] <<Case 5-2>> When LP-HARQ and HP-HARQ are transmitted by HP-PUCCH and HP-PUSCH has Part 1 CSI reporting and Part 2 CSI reporting, the following UE operation may be applied.

[0246] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #5 above may apply, e.g., the UE may multiplex the HP-HARQ onto the HP-PUSCH and transmit it, and drop the LP-HARQ.

[0247] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 5-2-1 to 5-2-2 may be applied.

[0248] Option 5-2-1: The UE operation #5 described above may be applied. For example, the UE may multiplex HP-HARQ onto HP-PUSCH and transmit it, and drop LP-HARQ. When option 5-2-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH. This can simplify the UE operation.

[0249] Option 5-2-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex LP-HARQ and HP-HARQ on the HP-PUCCH resource and transmit the HP-PUSCH, which overlaps with the HP-PUCCH in the time domain. When Option 5-2-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same.

[0250] Support for simultaneous transmission of HP-PUCCH and HP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with HP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., LP-HARQ / HP-HARQ) to the corresponding TRP.

[0251] As a variation of option 5-1-2 / 5-2-2, the UE may multiplex the HP-HARQ onto the HP-PUSCH and the LP-HARQ onto the HP-PUCCH, and transmit the HP-PUCCH and the HP-PUSCH simultaneously. Alternatively, as another variation of option 5-1-2 / 5-2-2, the UE may multiplex the HP-HARQ onto the HP-PUSCH and the LP-HARQ onto the LP-PUCCH, and transmit the LP-PUCCH and the HP-PUSCH simultaneously.

[0252] In at least one of Case 5-1 and Case 5-2, different options may be applied based on the feedback mode (e.g., ackNackFeedbackMode) provided / configured to the UE. For example, if the feedback mode is joint (e.g., ackNackFeedbackMode=joint), Option 5-1-1 / 5-2-1 may be applied. If the feedback mode is separate (e.g., ackNackFeedbackMode=separate), Option 5-1-2 / 5-2-2 may be applied.

[0253] Sixth Embodiment The sixth embodiment relates to another example of UE operation based on the priority of simultaneously transmitted UL channels (e.g., STxMP PUCCH+PUSCH). The sixth embodiment may be applied alone or in combination with other embodiments.

[0254] The UE may be configured with higher layer parameters (eg, uci-MuxWithDiffPrio) related to multiplexing of UCIs with different priorities (eg, HARQ-ACKs).

[0255] For example, when the higher layer parameter (e.g., uci-MuxWithDiffPrio) is configured and a PUCCH with a first priority (hereinafter also referred to as HP-PUCCH) and a PUSCH with a second priority lower than the first priority (hereinafter also referred to as LP-PUSCH) overlap in the time domain, the following UE operation #6 (or multiplexing method) may be supported / applied.

[0256] [UE Operation #6 / Multiplexing Method] For "HP-PUCCH with HP-HARQ" and "LP-PUSCH without CSI, or LP-PUSCH with single-part CSI, or LP-PUSCH with Part 1 CSI reporting and Part 2 CSI reporting", the UE may multiplex HP-HARQ onto the LP-PUSCH.

[0257] For "HP-PUCCH with HP-HARQ" and "LP-PUSCH with configuration grant UCI (e.g., CG-UCI), Part 1 CSI, and Part 2 CSI," the UE may multiplex HP-HARQ onto the LP-PUSCH. On the other hand, the UE may drop Part 2 CSI of the LP-PUSCH.

[0258] For "HP-PUCCH with HP-HARQ and LP-HARQ" and "LP-PUSCH without CSI or LP-PUSCH with single-part CSI", the UE may multiplex HP-HARQ and LP-HARQ onto the LP-PUSCH.

[0259] For "HP-PUCCH with HP-HARQ and LP-HARQ" and "LP-PUSCH with Part 1 CSI reporting and Part 2 CSI reporting", the UE may multiplex the HP-HARQ and LP-HARQ onto the LP-PUSCH. On the other hand, the UE may drop Part 2 CSI of the LP-PUSCH.

[0260] In UE action #6, the PUCCH with HARQ-ACK (eg, HP-PUCCH) may be a PUCCH without repetition.

[0261] [STxMP PUCCH+PUSCH] When a UE supports STxMP PUCCH+PUSCH / STxMP PUCCH+PUSCH is configured (or enabled) in the UE by higher layer parameters, multiplexing of UCI with different priorities (e.g., HARQ-ACK, etc.) is enabled for PUCCH / PUSCH, and PUCCH transmission and PUSCH transmission with different priorities (e.g., HP-PUCCH and LP-PUSCH) overlap in the time domain, an applicable UE operation may be determined based on predetermined conditions.

[0262] The UE operation to be applied may be determined based on at least one of the following predetermined conditions: the TRP / panel / CORESET pool index to which the PUCCH and the PUSCH correspond (e.g., whether they correspond to the same TRP / different TRP), the content of the UCI of the HP-PUCCH, and the content of the UCI of the LP-PUSCH. For example, when PUCCH transmission and PUSCH transmission with different priorities (e.g., HP-PUCCH and LP-PUSCH) overlap in the time domain, at least one of the following Cases 6-1 to 6-4 may be supported / applied.

[0263] <Case 6-1> For "HP-PUCCH with HP-HARQ" and "LP-PUSCH without CSI, or LP-PUSCH with single-part CSI, or LP-PUSCH with Part 1 CSI reporting and Part 2 CSI reporting", the following UE operations may be applied.

[0264] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #6 above may apply, e.g., the UE may multiplex HP-HARQ information onto the LP-PUSCH.

[0265] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 6-1-1 to 6-1-2 may be applied.

[0266] Option 6-1-1: The UE operation #6 described above may be applied. For example, the UE may multiplex HP-HARQ information onto the LP-PUSCH (see FIG. 14A). In FIG. 14A, the HP-PUCCH and the LP-PUSCH are associated with different TRP / panel / CORESET pool indices, and the HARQ-ACK of the HP-PUCCH (HP-HARQ) is multiplexed onto the LP-PUSCH for transmission.

[0267] When Option 6-1-1 is applied, the same UE behavior applies regardless of the TRP / Panel / CORESET pool index associated with the PUCCH and PUSCH, which can simplify the UE behavior.

[0268] Option 6-1-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex HP-HARQ onto the HP-PUCCH resource and transmit the LP-PUSCH, which overlaps with the HP-PUCCH in the time domain (see FIG. 14B). FIG. 14B shows a case where the HP-PUCCH and the LP-PUSCH are associated with different TRP / panel / CORESET pool indices and the HP-PUCCH and the LP-PUSCH with HP-HARQ are simultaneously transmitted.

[0269] When option 6-1-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same or not.

[0270] Support for simultaneous transmission of HP-PUCCH and LP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with LP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., HP-HARQ) to the corresponding TRP.

[0271] <<Case 6-2>> For the "HP-PUCCH with HP-HARQ" and the "LP-PUSCH with configuration grant UCI (e.g., CG-UCI), Part 1 CSI, and Part 2 CSI," the following UE operations may be applied.

[0272] If the PUCCH and PUSCH are associated with the same TRP / Panel / CORESET pool index, then UE action #6 above may apply, e.g., the UE may multiplex HP-HARQ information onto the LP-PUSCH and drop Part 2 CSI from the LP-PUSCH.

[0273] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 6-2-1 to 6-2-2 may be applied.

[0274] Option 6-2-1 The UE operation #6 described above may be applied. For example, the UE may multiplex HP-HARQ information onto the LP-PUSCH and drop Part 2 CSI of the LP-PUSCH. When option 6-2-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH. This can simplify the UE operation.

[0275] Option 6-2-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex HP-HARQ onto the HP-PUCCH resource and transmit an LP-PUSCH (e.g., an LP-PUSCH having CG-UCI, Part 1 CSI, and Part 2 CSI) that overlaps with the HP-PUCCH in the time domain. When Option 6-2-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and the PUSCH are the same.

[0276] Support for simultaneous transmission of HP-PUCCH and LP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with LP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., HP-HARQ) to the corresponding TRP.

[0277] <<Case 6-3>> For the “HP-PUCCH with HP-HARQ and LP-HARQ” and the “LP-PUSCH without CSI or LP-PUSCH with single-part CSI”, the following UE operations may be applied.

[0278] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #6 above may apply, e.g., the UE may multiplex HP-HARQ and LP-HARQ onto the LP-PUSCH.

[0279] When PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 6-3-1 to 6-3-2 may be applied.

[0280] Option 6-3-1 The UE operation #6 described above may be applied. For example, the UE may multiplex HP-HARQ and LP-HARQ onto the LP-PUSCH. When option 6-3-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool index associated with the PUCCH and PUSCH. This can simplify the UE operation.

[0281] Option 6-3-2: PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex HP-HARQ and LP-HARQ on the HP-PUCCH resource and transmit the LP-PUSCH, which overlaps the HP-PUCCH in the time domain. When Option 6-3-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH are the same.

[0282] Support for simultaneous transmission of HP-PUCCH and LP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with LP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., HP-HARQ / LP-HARQ) to the corresponding TRP.

[0283] <<Case 6-4>> For the "HP-PUCCH with HP-HARQ and LP-HARQ" and the "LP-PUSCH with Part 1 CSI reporting and Part 2 CSI reporting", the following UE operations may be applied.

[0284] If the PUCCH and PUSCH are associated with the same TRP / panel / CORESET pool index, then UE action #6 above may apply, e.g., the UE may multiplex HP-HARQ and LP-HARQ onto the LP-PUSCH and drop Part 2 CSI from the LP-PUSCH.

[0285] If PUCCH and PUSCH are associated with different TRP / panel / CORESET pool indices, at least one of options 6-4-1 to 6-4-2 may be applied.

[0286] Option 6-4-1 The UE operation #6 described above may be applied. For example, the UE may multiplex HP-HARQ and LP-HARQ onto the LP-PUSCH and drop Part 2 CSI of the LP-PUSCH. When option 6-4-1 is applied, the same UE operation is applied regardless of the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH. This can simplify the UE operation.

[0287] Option 6-4-2 PUCCH and PUSCH may be transmitted simultaneously. For example, the UE may multiplex HP-HARQ and LP-HARQ on the HP-PUCCH resource and transmit the multiplexed HP-PUCCH and transmit an LP-PUSCH (e.g., an LP-PUSCH having Part 1 CSI reporting and Part 2 CSI reporting) that overlaps with the HP-PUCCH in the time domain. When Option 6-4-2 is applied, different UE behavior may be applied depending on whether the TRP / panel / CORESET pool indexes associated with the PUCCH and the PUSCH are the same.

[0288] Support for simultaneous transmission of HP-PUCCH and LP-PUSCH corresponding to different TRPs (or transmission of HP-PUCCH overlapping with LP-PUSCH) makes it possible to directly feed back the UCI of HP-PUCCH (e.g., HP-HARQ / LP-HARQ) to the corresponding TRP.

[0289] In at least one of Case 6-1 to Case 6-4, different options may be applied based on the feedback mode (e.g., ackNackFeedbackMode) provided / configured to the UE. For example, if the feedback mode is joint (e.g., ackNackFeedbackMode=joint), Options 6-1-1, 6-2-1, 6-3-1, and 6-4-1 may be applied. If the feedback mode is separate (e.g., ackNackFeedbackMode=separate), Options 6-1-2, 6-2-2, 6-3-2, and 6-4-2 may be applied.

[0290] Seventh Embodiment The seventh embodiment relates to another example of UE operation when STxMP including at least an uplink control channel (e.g., PUCCH) is supported. The seventh embodiment may be applied alone or in combination with other embodiments.

[0291] When a first UL transmission (e.g., PUCCH / PUSCH) having a first priority and a second UL transmission (e.g., PUCCH / PUSCH) having a second priority lower than the first priority overlap in the time domain (condition 7-1), and an upper layer parameter (e.g., uci-MuxWithDiffPrio) enabling multiplexing of UCIs having different priorities (e.g., HARQ-ACKs) is not configured (condition 7-2), or when the upper layer parameter (e.g., uci-MuxWithDiffPrio) is configured but in a case other than a predetermined case (condition 7-3), the UE may drop the second UL transmission having the second priority and perform control to transmit the first UL transmission having the first priority.

[0292] The predetermined case may be, for example, at least one of UE operation #3 to UE operation #6 shown in the third to sixth embodiments.

[0293] When STxMP including PUCCH (e.g., STxMP PUCCH+PUCCH / STxMP PUCCH+PUSCH) is supported / enabled by higher layer parameters, if condition 7-1, condition 7-2 or condition 7-3 is satisfied, the UE operation to be applied may be determined based on the TRP / panel / CORESET pool index to which the first UL transmission and the second UL transmission correspond (e.g., whether they correspond to the same TRP / different TRP).

[0294] If the first UL transmission (e.g., HP-PUCCH / HP-PUSCH) and the second UL transmission (e.g., LP-PUCCH / PUSCH) are associated with the same TRP / Panel / CORESET pool index, the UE may be controlled to drop the second UL transmission (e.g., LP-PUCCH / PUSCH) and transmit the first UL transmission (e.g., HP-PUCCH / HP-PUSCH).

[0295] If the first UL transmission (e.g., HP-PUCCH / HP-PUSCH) and the second UL transmission (e.g., LP-PUCCH / PUSCH) are associated with different TRP / panel / CORESET pool indices, at least one of Option 7-1 to Option 7-2 may be applied.

[0296] Option 7-1: The UE may be controlled to drop the second UL transmission (e.g., LP-PUCCH / PUSCH) and transmit the first UL transmission (e.g., HP-PUCCH / HP-PUSCH). When option 7-1 is applied, the same UE behavior applies regardless of the TRP / panel / CORESET pool indexes associated with the PUCCH and PUSCH. This can simplify the UE behavior.

[0297] Option 7-2: The UE may control the simultaneous transmission of a first UL transmission (e.g., HP-PUCCH / HP-PUSCH) and a second UL transmission (e.g., LP-PUCCH / PUSCH). When Option 7-2 is applied, different UE behavior may be applied depending on whether the TRP / Panel / CORESET pool index associated with the first UL transmission (e.g., HP-PUCCH / HP-PUSCH) and the second UL transmission (e.g., LP-PUCCH / PUSCH) are the same or not.

[0317] (Wireless Communication System) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0318] 15 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may be simply referred to as system 1) may be a system that realizes communication using Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) specified by the Third Generation Partnership Project (3GPP).

[0319] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0320] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (Master Node (MN)), and the NR base station (gNB) is the secondary node (Secondary Node (SN)). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0321] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0322] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The locations and numbers of the cells and user terminals 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0323] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CCs) and dual connectivity (DC).

[0324] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a higher frequency band than FR2.

[0325] Furthermore, the user terminal 20 may perform communication using at least one of time division duplex (TDD) and frequency division duplex (FDD) in each CC.

[0326] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0327] The base station 10 may be connected to the core network 30 directly or via another base station 10. The core network 30 may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

[0328] The core network 30 may include network functions (Network Functions (NF)) such as a User Plane Function (UPF), an Access and Mobility management Function (AMF), a Session Management Function (SMF), a Unified Data Management (UDM), an Application Function (AF), a Data Network (DN), a Location Management Function (LMF), and Operation, Administration and Maintenance (Management) (OAM). A single network node may provide multiple functions. Communication with an external network (e.g., the Internet) may also be performed via the DN.

[0329] The user terminal 20 may be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0330] An Orthogonal Frequency Division Multiplexing (OFDM)-based radio access scheme may be used in the wireless communication system 1. For example, Cyclic Prefix OFDM (CP-OFDM), Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), or the like may be used in at least one of the downlink (DL) and uplink (UL).

[0331] The radio access scheme may also be called a waveform. Note that in the wireless communication system 1, other radio access schemes (e.g., other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0332] In the wireless communication system 1, a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc. may be used as the downlink channel.

[0333] Furthermore, in the wireless communication system 1, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20, an uplink control channel (Physical Uplink Control Channel (PUCCH)), a random access channel (Physical Random Access Channel (PRACH)), or the like may be used as an uplink channel.

[0334] The PDSCH transmits user data, higher layer control information, a System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit a Master Information Block (MIB).

[0335] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information for at least one of the PDSCH and the PUSCH.

[0336] Note that the DCI for scheduling the PDSCH may be referred to as a DL assignment, a DL DCI, etc., and the DCI for scheduling the PUSCH may be referred to as a UL grant, a UL DCI, etc. Note that the PDSCH may be replaced with DL data, and the PUSCH may be replaced with UL data.

[0337] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources for searching for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or more search spaces. The UE may monitor the CORESET associated with a certain search space based on the search space configuration.

[0338] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be referred to as a search space set. Note that the terms "search space," "search space set," "search space configuration," "search space set configuration," "CORESET," "CORESET configuration," and the like in the present disclosure may be read interchangeably.

[0339] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), delivery confirmation information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0364] In this example, the functional blocks of the characteristic parts of the present embodiment are mainly shown, and it may be assumed that the user terminal 20 also has other functional blocks necessary for wireless communication. Some of the processing of each unit described below may be omitted.

[0374] Whether or not to apply DFT processing may be based on the setting of transform precoding. When transform precoding is enabled for a certain channel (e.g., PUSCH), the transceiver unit 220 (transmission processing unit 2211) may perform DFT processing as the transmission processing to transmit the channel using a DFT-s-OFDM waveform, and if not, it may not be necessary to perform DFT processing as the transmission processing.

[0380] The transmitting unit and receiving unit of the user terminal 20 in the present disclosure may be configured by at least one of the transmitting / receiving unit 220 and the transmitting / receiving antenna 230.

[0381] The transceiver unit 220 may receive information regarding a feedback mode of a delivery acknowledgement signal (HARQ-ACK).

[0383] If the feedback mode is configured as joint or if the UCI does not include HARQ-ACK, the UE behavior may be the same as the UE behavior applied when multiple PUCCHs associated with the same transmission / reception point or the same control resource set pool index overlap in the time domain.

[0384] When an uplink control channel (PUCCH) and an uplink shared channel (PUSCH) associated with different transmission / reception points or different control resource set pool indexes overlap in the time domain, the control unit 210 may control to apply different UE operations in UL transmission based on at least one of the feedback mode of a delivery acknowledgement signal (HARQ-ACK) and the content included in the uplink control information (UCI) corresponding to the PUCCH.

When the feedback mode is set to separate and the UCI includes HARQ-ACK, the control unit 210 may control to transmit both the PUCCH having the UCI and the PUSCH.

[0386] When the feedback mode is set to joint or when the UCI does not include HARQ-ACK, the UE behavior may be the same as the UE behavior applied when PUCCH and PUSCH associated with the same transmission / reception point or the same control resource set pool index overlap in the time domain.

[0387] The transceiver 220 may receive information instructing activation of multiplexing of uplink control information (UCI) with different priorities. When multiple uplink control channels (PUCCHs) with different priorities overlap in the time domain, the controller 210 may control UE operation in UL transmission based on at least one of transmission / reception points or control resource set pool indexes associated with each of the multiple PUCCHs and UCI corresponding to each of the multiple PUCCHs.

[0388] When multiple PUCCHs are associated with the same transmission / reception point or the same control resource set pool index, the control unit 210 may control to transmit at least a portion of UCI corresponding to a PUCCH with lower priority using a PUCCH with higher priority. When multiple PUCCHs are associated with different transmission / reception points or different control resource set pool indexes, the control unit 210 may control to transmit multiple PUCCHs. When multiple PUCCHs are associated with different transmission / reception points or different control resource set pool indexes, the control unit 210 may control to apply different UE operations in UL transmission based on feedback modes of delivery acknowledgement signals (HARQ-ACK).

When the PUCCH and the PUSCH are associated with different transmission / reception points or different control resource set pool indexes, the control unit 210 may control to transmit both the PUCCH and the PUSCH. When the PUCCH and the PUSCH are associated with different transmission / reception points or different control resource set pool indexes, the control unit 210 may control to apply different UE operations in UL transmission based on the feedback mode of the delivery acknowledgement signal (HARQ-ACK).

[0391] (Hardware Configuration) Note that the block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices. The functional block may be realized by combining software with the single device or the multiple devices.

[0393] For example, a base station, a user terminal, etc. according to an embodiment of the present disclosure may function as a computer that performs processing of the wireless communication method of the present disclosure. Fig. 18 is a diagram illustrating an example of the hardware configuration of a base station and a user terminal according to an embodiment. The above-described base station 10 and user terminal 20 may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0394] In the present disclosure, the terms apparatus, circuit, device, section, unit, etc. may be used interchangeably. The hardware configurations of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the drawings, or may be configured to exclude some of the devices.

[0395] For example, although only one processor 1001 is shown, there may be multiple processors. Furthermore, processing may be performed by one processor, or processing may be performed by two or more processors simultaneously, serially, or in other ways. Furthermore, processor 1001 may be implemented by one or more chips.

[0396] Each function in the base station 10 and the user terminal 20 is realized, for example, by loading specified software (programs) onto hardware such as a processor 1001 and a memory 1002, causing the processor 1001 to perform calculations, control communication via the communication device 1004, and control at least one of reading and writing data in the memory 1002 and the storage 1003.

[0397] The processor 1001, for example, runs an operating system to control the entire computer. The processor 1001 may be configured as a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. For example, at least a part of the above-mentioned control unit 110 (210), transceiver unit 120 (220), etc. may be realized by the processor 1001.

[0398] The processor 1001 also reads programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002 and executes various processes in accordance with these. The programs used are those that cause a computer to execute at least some of the operations described in the above-described embodiments. For example, the control unit 110 (210) may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and the other functional blocks may be implemented in a similar manner.

[0399] The memory 1002 is a computer-readable recording medium and may be configured by at least one of, for example, Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically EEPROM (EEPROM), Random Access Memory (RAM), or other suitable storage medium. The memory 1002 may also be referred to as a register, cache, main memory, etc. The memory 1002 may store executable programs (program codes), software modules, etc. for implementing a wireless communication method according to an embodiment of the present disclosure.

[0400] Storage 1003 is a computer-readable recording medium and may be composed of at least one of, for example, a flexible disk, a floppy disk, a magneto-optical disk (e.g., a compact disc (e.g., a Compact Disc ROM (CD-ROM)), a digital versatile disc, a Blu-ray disc), a removable disk, a hard disk drive, a smart card, a flash memory device (e.g., a card, a stick, a key drive), a magnetic stripe, a database, a server, or other suitable storage medium. Storage 1003 may also be referred to as an auxiliary storage device.

[0401] The communication device 1004 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, or a communication module. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0402] The input device 1005 is an input device (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that accepts input from the outside. The output device 1006 is an output device (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.) that outputs to the outside. Note that the input device 1005 and the output device 1006 may be integrated into one device (e.g., a touch panel).

[0403] Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0404] Furthermore, the base station 10 and the user terminal 20 may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized using this hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0405] (Modifications) Note that terms described in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applicable standard. A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0406] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0407] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by a transceiver in the frequency domain, and specific windowing performed by a transceiver in the time domain.

[0408] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may also be a time unit based on numerology.

[0409] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0410] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0411] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0412] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0413] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0414] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0415] A TTI having a time length of 1 ms may be called a regular TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0416] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and greater than or equal to 1 ms.

[0417] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain.
