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. To improve UL throughput / reliability, simultaneous UL transmission using multiple panels (e.g., simultaneous multi-panel UL transmission (SiMPUL / sTxMP)) is being considered for support.

[0006] When multi-panel simultaneous UL transmission is supported, the UE transmits UL from two panels simultaneously. However, the reporting / calculation of the Power Headroom Report (PHR) in this case is unclear. For example, the events / conditions that trigger the PHR are unclear. This may result in inappropriate transmission control and reduced communication throughput.

[0007] Therefore, one object of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can appropriately control transmission power.

[0008] A terminal according to one aspect of the present disclosure includes a receiving unit that receives, for a serving cell, at least one of a plurality of power headroom report (PHR) modes, a plurality of measurement reference signal (SRS) resource sets, a plurality of transmission configuration indication (TCI) state instructions, and information regarding multi-panel transmission, and a control unit that determines the number of PHRs to be reported based on whether the plurality of PHR modes are configured when multi-downlink control information (DCI)-based simultaneous multi-panel (STxMP) uplink shared channel (PUSCH) repeat transmission is enabled.

[0009] According to one aspect of the present disclosure, transmission power control can be performed appropriately.

[0011] (TCI, spatial relationship, QCL) In NR, it is considered to control the reception processing (e.g., at least one of reception, demapping, demodulation, and decoding) and transmission processing (e.g., at least one of transmission, mapping, precoding, modulation, and encoding) in a UE of at least one of a signal and a channel (referred to as a signal / channel) based on a transmission configuration indication state (TCI state).

[0012] The TCI state may represent that which is applied to a downlink signal / channel, and the equivalent of the TCI state that is applied to an uplink signal / channel may be expressed as a spatial relation.

[0013] The TCI state is information about the Quasi-Co-Location (QCL) of signals / channels, and may also be called spatial reception parameters, spatial relation information, etc. The TCI state may be configured in the UE for each channel or signal.

[0014] The QCL is an index indicating the statistical properties of signals / channels. For example, if a signal / channel has a QCL relationship with another signal / channel, it may mean that it can be assumed that at least one of a Doppler shift, a Doppler spread, an average delay, a delay spread, and a spatial parameter (e.g., a spatial Rx parameter) is the same between these different signals / channels (i.e., the signals / channels have a QCL with respect to at least one of these).

[0015] The spatial reception parameters may correspond to a reception beam (e.g., a reception analog beam) of the UE, and the beam may be identified based on a spatial QCL. The QCL (or at least one element of the QCL) in the present disclosure may be replaced with sQCL (spatial QCL).

[0016] A plurality of types of QCLs (QCL types) may be defined. For example, four QCL types A to D may be provided, each having different parameters (or parameter sets) that can be assumed to be the same.

[0017] The UE's assumption that a Control Resource Set (CORESET), channel, or reference signal has a specific QCL (e.g., QCL type D) relationship with another CORESET, channel, or reference signal may be referred to as a QCL assumption.

[0018] The UE may determine at least one of a transmit beam (Tx beam) and a receive beam (Rx beam) for a signal / channel based on the TCI condition or QCL assumption of the signal / channel.

[0019] The TCI state may be, for example, information about the QCL between the channel of interest (in other words, the Reference Signal (RS) for that channel) and another signal (e.g., another RS). The TCI state may be set (indicated) by higher layer signaling, physical layer signaling, or a combination thereof.

[0020] The physical layer signaling may be, for example, Downlink Control Information (DCI).

[0021] The channel for which the TCI state or spatial relationship is set (specified) may be, for example, at least one of a downlink shared channel (Physical Downlink Shared Channel (PDSCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), an uplink shared channel (Physical Uplink Shared Channel (PUSCH)), and an uplink control channel (Physical Uplink Control Channel (PUCCH)).

[0022] Furthermore, the RS that has a QCL relationship with the channel may be, for example, at least one of a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), a tracking CSI-RS (also called a tracking reference signal (TRS)), and a QCL detection reference signal (also called a QRS).

[0023] An SSB is a signal block including at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). An SSB may also be referred to as an SS / PBCH block.

[0024] An RS of QCL type X in a TCI state may refer to an RS that has a QCL type X relationship with a certain channel / signal (DMRS), and this RS may be called a QCL source of QCL type X in the TCI state.

[0025] Physical Layer Procedures for Data / Antenna Port QCL A UE can configure a list of up to M TCI-State settings in the higher layer parameter PDSCH-Config for PDSCH decoding according to a detected PDCCH with DCI intended for the UE and a given serving cell, where M depends on the UE capability maxNumberConfiguredTCIstatesPerCC.

[0026] Each TCI-State includes parameters for configuring a QCL relationship between one or two downlink reference signals and a DMRS port of a PDSCH, a DMRS port of a PDCCH, or a CSI-RS port of a CSI-RS resource, which is configured by the higher layer parameter qcl-Type1 for the first DL RS and the higher layer parameter qcl-Type2 for the second DL RS (if configured).

[0027] In the case of two DL RSs, the multiple QCL types are not the same, regardless of whether the references are to the same DL RS or to different DL RSs. The QCL type corresponding to each DL RS is given by the higher layer parameter qcl-Type in QCL-Info and takes one of the following values: - 'typeA': {Doppler shift, Doppler spread, average delay, delay spread} - 'typeB': {Doppler shift, Doppler spread} - 'typeC': {Doppler shift, average delay} - 'typeD': {Spatial Rx parameter}

[0028] RRC Protocol Specification / RRC IE / TCI-State The TCI-State associates one or two DL Reference Signals (RS) with a corresponding QCL type. If an additional physical cell identifier (PCI) is configured for that RS, it is set to the same value for both DL RSs.

[0029] (Unified / Common TCI Framework) The unified TCI framework allows multiple types of channels / RSs (UL / DL) to be controlled by a common framework. The unified TCI framework does not specify TCI states or spatial relationships for each channel as in Rel. 15. Instead, it may specify a common beam (common TCI state) and apply it to all UL and DL channels, or it may apply a common beam for UL to all UL channels and a common beam for DL ​​to all DL channels.

[0030] One common beam for both DL and UL, or one common beam for DL ​​and one common beam for UL (two common beams overall) are considered.

[0031] The UE may assume the same TCI state for UL and DL (joint TCI state, joint TCI pool, joint common TCI pool, joint TCI state set). The UE may assume different TCI states for UL and DL (separate TCI state, separate TCI pool, UL separate TCI pool and DL separate TCI pool, separate common TCI pool, UL common TCI pool and DL common TCI pool).

[0032] The default beams for UL and DL may be aligned via MAC CE based beam management (MAC CE level beam indication). The default TCI state of the PDSCH may be updated to align with the default UL beam (spatial relationship).

[0033] DCI-based beam management (DCI-level beam indication) may indicate a common beam / unified TCI state from the same TCI pool for both UL and DL (joint common TCI pool, joint TCI pool, set). X (>1) TCI states may be activated by the MAC CE. The UL / DL DCI may select one from the X active TCI states. The selected TCI state may apply to both UL and DL channels / RS.

[0034] The TCI pool (set) may be multiple TCI states configured by RRC parameters, or multiple TCI states (active TCI states, active TCI pools, sets) activated by MAC CE among the multiple TCI states configured by RRC parameters. Each TCI state may be a QCL type A / D RS. SSB, CSI-RS, or SRS may be configured as the QCL type A / D RS.

[0035] The number of TCI states corresponding to each of one or more TRPs may be specified. For example, the number N (≧1) of TCI states applied to UL channels / RSs (UL TCI states) and the number M (≧1) of TCI states applied to DL channels / RSs (DL TCI states) may be specified. At least one of N and M may be notified / configured / instructed to the UE via higher layer signaling / physical layer signaling.

[0036] In the present disclosure, when N=M=X (X is any integer), it may mean that X TCI states (joint TCI states) common to UL and DL (corresponding to X TRPs) are notified / configured / indicated to the UE. Also, when N=X (X is any integer) and M=Y (Y may be any integer, Y=X), it may mean that X UL TCI states (corresponding to X TRPs) and Y DL TCI states (i.e., separate TCI states) (corresponding to Y TRPs) are notified / configured / indicated to the UE.

[0037] For example, when N=M=1 is written, this may mean that a TCI state common to one UL and DL for a single TRP is notified / configured / indicated to the UE (joint TCI state for a single TRP).

[0038] Also, for example, when N=1 and M=1 are written, this may mean that one UL TCI state and one DL TCI state for a single TRP are separately notified / configured / instructed to the UE (separate TCI states for a single TRP).

[0039] Also, for example, when N=M=2 is written, this may mean that a TCI state common to multiple (two) ULs and DLs for multiple (two) TRPs is notified / configured / instructed to the UE (joint TCI state for multiple TRPs).

[0040] Also, for example, when N=2 and M=2, it may mean that multiple (two) UL TCI states and multiple (two) DL TCI states for multiple (two) TRPs are notified / configured / instructed to the UE (separate TCI states for multiple TRPs).

[0041] In the above example, the values ​​of N and M are 1 or 2, but the values ​​of N and M may be 3 or more, and N and M may be different.

[0042] It is being considered that N=M=1 will be supported in Rel. 17. It is being considered that other cases will be supported in Rel. 18 and later.

[0043] In the example of Figure 1A, RRC parameters (information elements) configure multiple TCI states for both DL and UL. The MAC CE may activate multiple TCI states from the configured multiple TCI states. A DCI may indicate one of the activated multiple TCI states. The DCI may be a UL / DL DCI. The indicated TCI state may apply to at least one (or all) of the UL / DL channels / RS. One DCI may indicate both UL TCI and DL TCI.

[0044] In the example of this figure, a point may be one TCI state that applies to both UL and DL, or two TCI states that apply to UL and DL respectively.

[0045] At least one of the multiple TCI states configured by the RRC parameters and the multiple TCI states activated by the MAC CE may be referred to as a TCI pool (common TCI pool, joint TCI pool, TCI state pool). The multiple TCI states activated by the MAC CE may be referred to as an active TCI pool (active common TCI pool).

[0046] In the present disclosure, higher layer parameters (RRC parameters) for setting multiple TCI states may be referred to as configuration information for setting multiple TCI states, or simply as "configuration information." Also, in the present disclosure, being instructed to set one of multiple TCI states using DCI may mean receiving indication information instructing one of the multiple TCI states included in DCI, or may simply mean receiving "instruction information."

[0047] In the example of Figure 1B, the RRC parameters configure multiple TCI states (joint common TCI pools) for both DL and UL. The MAC CE may activate multiple TCI states (active TCI pools) from the configured multiple TCI states. Separate active TCI pools for each of the UL and DL may be configured / activated.

[0048] The DL DCI or a new DCI format may select (indicate) one or more (e.g., one) TCI states. The selected TCI state may apply to one or more (or all) DL channels / RSs. The DL channels may be PDCCH / PDSCH / CSI-RS. The UE may determine the TCI state of each DL channel / RS using the TCI state behavior (TCI framework) of Rel. 16. The UL DCI or a new DCI format may select (indicate) one or more (e.g., one) TCI states. The selected TCI state may apply to one or more (or all) UL channels / RSs. The UL channels may be PUSCH / SRS / PUCCH. In this way, different DCIs may indicate UL TCI and DL DCI separately.

[0049] It is assumed that in Rel. 17 NR and later, the MAC CE / DCI supports beam activation / indication to a TCI state associated with a different physical cell identifier (PCI), and in Rel. 18 NR and later, the MAC CE / DCI supports indicating a serving cell change to a cell with a different PCI.

[0050] [Physical Layer Procedures for Data / Antenna Port QCL] In PDSCH-Config, the UE can configure a list of up to 128 DLorJointTCIState configurations to provide reference signals for PDSCH DMRS and PDCCH DMRS and CSI-RS within a CC, and also to provide a reference for determining the UL TX (Transmit) spatial filter for PUSCH and PUCCH resources and SRS within a CC based on dynamic and configuration grants, if available.

[0051] If there is no DLorJointTCIState or UL-TCIState (UL TCI state) configuration in the BWP in that CC, the UE may apply the DLorJointTCIState or UL-TCIState configuration from the reference BWP of the reference CC. If the UE has DLorJointTCIState or UL-TCIState configured in any CC in the same band, it does not assume that TCI-State, SpatialRelationInfo (spatial relation information), or PUCCH-SpatialRelationInfo (PUCCH spatial relation information) in that band are configured, except for SpatialRelationInfoPos (spatial relation information for position). The UE assumes that if the UE has TCI-State in any CC in the CC list configured by simultaneousTCI-UpdateList1-r16 (simultaneous TCI update list 1), simultaneousTCI-UpdateList2-r16 (simultaneous TCI update list 2), simultaneousSpatial-UpdatedList1-r16 (simultaneous spatial update list 1), or simultaneousSpatial-UpdatedList2-r16 (simultaneous spatial update list 2), the UE does not have DLorJointTCIState or UL-TCIState configured in any CC in that CC list.

[0052] The UE receives an activation command used to map up to eight TCI states and / or TCI state pairs, with one TCI state for DL ​​channels / signals and one TCI state for UL channels / signals, to codepoints in the DCI field 'Transmission Configuration Indication' (TCI) for one CC / DL BWP or set of CC / DL BWPs, if available. If a set of TCI state IDs is activated for a set of CC / DL BWPs, and also for one CC / DL BWP, if available, the same set of TCI state IDs applies to all DL and / or UL BWPs within the indicated CC, where the applicable list of CCs is determined by the CC indicated in the activation command. If the activation command maps DLorJointTCIState and / or UL-TCIState to only one TCI codepoint, the UE applies the indicated DLorJointTCIState and / or UL-TCIState to one or a set of CC / DL BWPs, and if the indicated mapping to one single TCI codepoint applies, the UE applies the indicated DLorJointTCIState and / or UL-TCIState to one or a set of CC / DL BWPs.

[0053] If the bwp-id or cell for a QCL type A / D source RS in the QCL-Info of a TCI state with DLorJointTCIState set is not set, the UE shall assume that the QCL type A / D source RS is set in the CC / DL BWP to which the TCI state applies.

[0054] (TCI State Indication) The Rel. 17 unified TCI framework supports the following modes 1 to 3: [Mode 1] MAC CE based TCI state indication [Mode 2] DCI based TCI state indication by DCI format 1_1 / 1_2 with DL assignment [Mode 3] DCI based TCI state indication by DCI format 1_1 / 1_2 without DL assignment

[0055] A UE with a TCI state configured and activated with a Rel. 17 TCI State ID (e.g., tci-StateId_r17) receives DCI format 1_1 / 1_2 providing an indicated TCI state with the Rel. 17 TCI State ID for one CC, or receives DCI format 1_1 / 1_2 providing an indicated TCI state with the Rel. 17 TCI State ID for all CCs in the same CC list as the CC list configured by simultaneous TCI update list 1 or simultaneous TCI update list 2 (e.g., simultaneousTCI-UpdateList1 or simultaneousTCI-UpdateList2). DCI format 1_1 / 1_2 may or may not be accompanied by a DL assignment if one is available.

[0056] If DCI format 1_1 / 1_2 does not carry a DL assignment, the UE can assume (verify) the following for that DCI: - the CS-RNTI is used to scramble the CRC for the DCI; - the values ​​of the following DCI fields (special fields) are set as follows: - the redundancy version (RV) field is all '1's; - the modulation and coding scheme (MCS) field is all '1's; - the new data indicator (NDI) field is 0; - the frequency domain resource assignment (FDRA) field is all '0's for FDRA type 0, or all '1's for FDRA type 1, or all '0's for Dynamic Switch (similar to PDCCH validation for release of DL semi-persistent scheduling (SPS) or UL grant type 2 scheduling).

[0057] Note that the DCI in the above-mentioned mode 2 / mode 3 may be referred to as beam instruction DCI.

[0058] In Rel. 15 / 16, if a UE does not support active BWP changes via DCI, the UE ignores the BWP indicator field. A similar behavior is considered for the relationship between support for Rel. 17 TCI states and the interpretation of the TCI field. It is considered that if a UE is configured with Rel. 17 TCI states, the TCI field will always be present in DCI format 1_1 / 1_2, and if the UE does not support TCI updates via DCI, the UE will ignore the TCI field.

[0059] In Rel. 15 / 16, whether or not a TCI field is present (TCI presence information in DCI, tci-PresentInDCI) is set for each CORESET.

[0060] The TCI field in DCI format 1_1 is 0-bit if the higher layer parameter tci-PresentInDCI is not enabled, and 3-bit otherwise. If the BWP indicator field indicates a BWP other than the active BWP, the UE shall follow the following behavior: [Action] If the higher layer parameter tci-PresentInDCI is not enabled for the CORESET used for the PDCCH carrying that DCI format 1_1, the UE shall assume that tci-PresentInDCI is not enabled for all CORESETs in the indicated BWP; otherwise, the UE shall assume that tci-PresentInDCI is enabled for all CORESETs in the indicated BWP.

[0061] The TCI field in DCI format 1_2 is 0 bit if the higher layer parameter tci-PresentInDCI-1-2 is not set, otherwise it is 1, 2 or 3 bits determined by the higher layer parameter tci-PresentInDCI-1-2. If the BWP indicator field indicates a BWP other than the active BWP, the UE shall follow the following actions. [Operation] If the higher layer parameter tci-PresentInDCI-1-2 is not set for the CORESET used for the PDCCH carrying that DCI format 1_2, the UE shall assume that tci-PresentInDCI is not enabled for all CORESETs in the indicated BWP; otherwise, the UE shall assume that tci-PresentInDCI-1-2 for all CORESETs in the indicated BWP is set with the same value as tci-PresentInDCI-1-2 set for the CORESET used for the PDCCH carrying that DCI format 1_2.

[0062] 2A shows an example of a DCI-based joint DL / UL TCI status indication, in which a TCI status ID indicating the joint DL / UL TCI status is associated with a value of the TCI field for the joint DL / UL TCI status indication.

[0063] 2B shows an example of DCI-based separate DL / UL TCI status indication. At least one TCI status ID, indicating a DL-only TCI status or indicating a UL-only TCI status, is associated with a value of the TCI field for the separate DL / UL TCI status indication. In this example, TCI field values ​​000 to 001 are associated with only one TCI status ID for DL, TCI field values ​​010 to 011 are associated with only one TCI status ID for UL, and TCI field values ​​100 to 111 are associated with both one TCI status ID for DL ​​and one TCI status ID for UL.

[0064] (Indicated TCI State / Configured TCI State) For Rel. 17 TCI states, unified / common TCI state may mean the Rel. 17 TCI state indicated using (Rel. 17) DCI / MAC CE / RRC (indicated Rel. 17 TCI state).

[0065] In the present disclosure, the terms indicated Rel. 17 TCI state, indicated TCI state, unified / common TCI state, TCI state applicable to multiple types of signals (channels / RS), and TCI state for multiple types of signals (channels / RS) may be interpreted interchangeably.

[0066] The indicated Rel. 17 TCI state may be shared with at least one of the UE-specific reception of PDSCH / PDCC (updated using Rel. 17 DCI / MAC CE / RRC), PUSCH of dynamic grant (DCI) / configured grant, and multiple (e.g., all) dedicated PUCCH resources. The TCI state indicated by DCI / MAC CE / RRC may be referred to as the indicated TCI state or the unified TCI state.

[0067] Regarding the Rel. 17 TCI state, a TCI state other than the unified TCI state may refer to a Rel. 17 TCI state configured using (Rel. 17) MAC CE / RRC (configured Rel. 17 TCI state). In this disclosure, the terms configured Rel. 17 TCI state, configured TCI state, TCI state other than the unified TCI state, and TCI state applied to a specific type of signal (channel / RS) may be interpreted interchangeably.

[0068] The configured Rel. 17 TCI state may not be shared with at least one of the UE-specific reception of PDSCH / PDCC (updated using Rel. 17 DCI / MAC CE / RRC), PUSCH of dynamic grant (DCI) / configured grant, and multiple (e.g., all) dedicated PUCCH resources. The configured Rel. 17 TCI state may be configured by RRC / MAC CE per CORESET / per resource / per resource set, and may not be updated even if the indicated Rel. 17 TCI state (common TCI state) is updated.

[0069] It is being considered that the indicated Rel. 17 TCI state will be applied to UE-specific channels / signals (RS), and that the UE will be notified by higher layer signaling (RRC signaling) whether the indicated Rel. 17 TCI state or the configured Rel. 17 TCI state will be applied to non-UE-specific channels / signals.

[0070] It is being considered that the RRC parameters for the configured Rel. 17 TCI state (TCI state ID) will have the same configuration as the RRC parameters for the TCI state in Rel. 15 / 16. It is also being considered that the configured Rel. 17 TCI state will be configured / instructed per CORESET / per resource / per resource set using RRC / MAC CE. It is also being considered that the UE will determine the configuration / instruction based on specific parameters.

[0071] It is considered that the UE updates the indicated TCI state and the configured TCI state separately. For example, if the unified TCI state for the indicated TCI state is updated, the UE may not update the configured TCI state. It is also considered that the UE may determine whether to update the configured TCI state based on a specific parameter.

[0072] Furthermore, regarding the PDCCH / PDSCH, it is being considered to use higher layer signaling (RRC / MAC CE) to switch whether the indication Rel. 17 TCI state is applied or not (the configured Rel. 17 TCI state is applied, or a TCI state configured separately from the indication Rel. 17 TCI state is applied).

[0073] Regarding intra-cell beam indication (TCI state indication), it is being considered to support Rel. 17 TCI state indication for a UE-specific CORESET and its associated PDSCH, and a non-UE-specific CORESET and its associated PDSCH.

[0074] Also, for inter-cell beam indication (e.g., L1 / L2 inter-cell mobility), it is being considered to support Rel. 17 TCI state indication for a UE-specific CORESET and its associated PDSCH.

[0075] In Rel. 15, whether to indicate the TCI state for CORESET #0 was up to the implementation of the base station. In Rel. 15, for CORESET #0 for which a TCI state is indicated, the indicated TCI state is applied. For CORESET #0 for which a TCI state is not indicated, the SSB and QCL selected at the time of the latest (most recent) PRACH transmission are applied.

[0076] In the unified TCI state framework for Rel. 17 and later, the TCI state for CORESET #0 is being considered.

[0077] For example, in the unified TCI state framework for Rel. 17 and later, whether or not to apply the indicated Rel. 17 TCI state associated with the serving cell for the Rel. 17 TCI state indication in CORESET #0 is configured by RRC for each CORESET, and if not, the legacy MAC CE / RACH signaling mechanism may be used.

[0078] Note that the CSI-RS associated with the Rel. 17 TCI state applied to CORESET #0 may be QCL'd with the SSB associated with the serving cell PCI (physical cell ID) (similar to Rel. 15).

[0079] For CORESET #0, a CORESET with a common search space (CSS), and a CORESET with a CSS and a UE-specific search space (USS), whether to follow the Rel. 17 TCI state may be configured for each CORESET by an RRC parameter. If the Rel. 17 TCI state is not configured to be followed for that CORESET, the configured Rel. 17 TCI state may be applied to that CORESET.

[0080] For non-UE-dedicated channels / RSs (except CORESET), whether to follow the indicated Rel. 17 TCI state may be configured by an RRC parameter for each channel / resource / resource set. If the indicated Rel. 17 TCI state is not configured for that channel / resource / resource set, the configured Rel. 17 TCI state may apply to that channel / resource / resource set.

[0081] (PUSCH repetition) In Rel. 17, the introduction of PUSCH repetition is under consideration.

[0082] The RRC field and DCI field related to PUSCH repetition will be described below with reference to Figures 3A and 3B.

[0083] RRC fields related to PUSCH transmission defined up to Rel. 16 include a field related to the SRS resource set of the codebook (CB) / non-codebook (NCB), a field related to mapping (power control) between the SRI and the PUSCH (sri-PUSCH-MappingToAddModList), and a field related to P0 of the PUSCH for each SRI (p0-PUSCH-SetList).

[0084] DCI fields related to PUSCH transmission defined up to Rel. 16 include an SRS resource indicator field, a field indicating precoding information and the number of layers, a field related to the association between PTRS and DMRS, and a TPC command field.

[0085] In Rel. 17, if two SRS resource sets of CB / NCB are configured, an SRS resource set indicator field is added to DCI format 0_1 / 0_2.

[0086] The SRS Resource Set Indicator field has two bits. If the SRS Resource Set Indicator field indicates code point "00 (0)", it indicates single-TRP operation using the first TRP (TRP1). If the SRS Resource Set Indicator field indicates code point "01 (1)", it indicates single-TRP operation using the second TRP (TRP2). If the SRS Resource Set Indicator field indicates code point "10 (2)", it indicates multi-TRP operation with the first TRP (TRP1) followed by the second TRP (TRP2) in a PUSCH repetition. If the SRS Resource Set Indicator field indicates code point "11 (3)", it indicates multi-TRP operation with the second TRP (TRP2) followed by the first TRP (TRP1) in a PUSCH repetition (see Figure 3B).

[0087] When the SRS resource set indicator field is added to DCI format 0_1 / 0_2, new RRC fields are added: a field related to the mapping (power control) of the second SRI and the PUSCH (sri-PUSCH-MappingToAddModList2) and a field related to P0 of the PUSCH for each second SRI (p0-PUSCH-SetList2) (see FIG. 3A). These fields are used as fields for the second TRP (TRP2), and the existing fields are used as fields for the first TRP (TRP1).

[0088] Furthermore, when an SRS resource set indicator field is added to DCI format 0_1 / 0_2, a second SRS resource indicator field, a field indicating second precoding information and the number of layers, a field relating to the association of second PTRS and DMRS, and a second TPC command field are added to the DCI format (see FIG. 3A). These fields are used as fields for the second TRP (TRP2), and the existing fields are used as fields for the first TRP (TRP1).

[0089] (UL TCI state) In NR Rel. 16 and later, the use of the UL TCI state as a UL beam indication method is being considered. Notification of the UL TCI state is similar to notification of the UE's DL beam (DL TCI state). Note that the DL TCI state may be interchangeably read as the TCI state for PDCCH / PDSCH.

[0090] The channel / signal (which may be referred to as a target channel / RS) to which the UL TCI state is set (specified) may be, for example, at least one of a PUSCH (DMRS of PUSCH), a PUCCH (DMRS of PUCCH), a random access channel (Physical Random Access Channel (PRACH)), an SRS, etc.

[0091] Furthermore, the RS (source RS) that has a QCL relationship with the channel / signal may be, for example, a DL RS (e.g., SSB, CSI-RS, TRS, etc.) or a UL RS (e.g., SRS, SRS for beam management, etc.).

[0092] In the UL TCI state, an RS that has a QCL relationship with the channel / signal may be associated with a panel ID for receiving or transmitting the RS, which may be explicitly configured (or specified) or implicitly determined by higher layer signaling (e.g., RRC signaling, MAC CE, etc.).

[0093] The correspondence between the RS and the panel ID may be set by being included in the UL TCI status information, or may be set by being included in at least one of the resource setting information, spatial relationship information, etc. of the RS.

[0094] The QCL type indicated by the UL TCI status may be an existing QCL type A-D, or may be another QCL type, and may include a predetermined spatial relationship, associated antenna ports (port index), etc.

[0095] When a UE is assigned an associated panel ID for an UL transmission (e.g., assigned by a DCI), the UE may perform the UL transmission using the panel corresponding to the panel ID. The panel ID may be associated with a UL TCI state, and when a UL TCI state is assigned (or activated) for a given UL channel / signal, the UE may identify the panel to use for the UL channel / signal transmission according to the panel ID associated with the UL TCI state.

[0096] (Channels / RSs to which the indicated TCI state applies) The indicated TCI state by the MAC CE / DCI may apply to the following channels / RSs:

[0097] [PDCCH] - If followUnifiedTCIState is configured for CORESET0, the indicated TCI state applies. Otherwise, the Rel. 15 specifications apply for that CORESET. That is, CORESET0 follows the TCI state activated by the MAC CE or is QCL'd with SSB. - For CORESETs with USS / CSS type 3 and index other than 0, the indicated TCI state always applies. - For CORESETs with index other than 0 and at least CSS type other than 3, if followUnifiedTCIState is configured, the indicated TCI state applies. Otherwise, the configured TCI state for that CORESET applies to that CORESET.

[0098] [PDSCH] - The indicated TCI state always applies to all UE-dedicated PDSCHs. - For non-UE-dedicated PDSCHs (PDSCHs scheduled by DCI in CSS), the indicated TCI state may apply if followUnifiedTCIState is set (for the CORESET of the PDCCH that schedules that PDSCH). Otherwise, the configured TCI state for that PDSCH applies to that PDSCH. If followUnifiedTCIState is not set for a PDSCH, whether a non-UE-dedicated PDSCH follows the indicated TCI state may depend on whether followUnifiedTCIState is set for the CORESET used to schedule that PDSCH.

[0099] [CSI-RS] For an A-CSI-RS for CSI acquisition or beam management, if followUnifiedTCIState is set (for CORESET of the PDCCH that triggers that A-CSI-RS), the indicated TCI state applies. For other CSI-RSs, the configured TCI state for that CSI-RS applies.

[0100] [PUCCH] - For all dedicated PUCCH resources, the indicated TCI state always applies.

[0101] [PUSCH] - For dynamic / configured grant PUSCH, the indication TCI state always applies.

[0102] [SRS] - When the SRS resource set for the A-SRS used for beam management and the A / SP / P-SRS used for codebook (CB) / non-codebook (NCB) / antenna switching is configured to follow the unified TCI state, the indicated TCI state is applied. For other SRSs, the configured TCI state in the SRS resource set is applied.

[0103] (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.

[0104] <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 at a time from only one beam and panel (FIG. 4A).

[0105] <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 (see Figure 4B). In the example of Figure 4B, 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.

[0106] (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 (or 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).

[0107] 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.

[0108] 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.

[0109] <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.

[0110] In the example of Figure 5A, 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.

[0111] <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.

[0112] In the example of FIG. 5B, 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.

[0113] <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.

[0114] In the example of FIG. 5C , 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 method 3 can obtain gains through multiplexing and diversity. The total number of layers in the two panels is L.

[0115] 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).

[0116] (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.

[0117] 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.

[0118] <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 6A). In single DCI-based STxMP, the following scheme may be applied for UL transmission (e.g., PUSCH, PUCCH, or PUSCH+PUCCH).

[0119] 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. 6B). 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. 6C). Single Frequency Network (SFN)-based transmission scheme (PUCCH): One PUCCH is transmitted simultaneously from different panels (see Fig. 6D).

[0120] Figure 6B 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 multiple coherent panels, the UE may transmit repeated SDM PUSCH transmissions on the same time and frequency resources. Figure 6B shows a case where the time and frequency resources of Layer #1 and Layer #2 corresponding to the PUSCH are the same.

[0121] 6B 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.

[0122] Figure 6C 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).

[0123] 6D 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).

[0124] 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.

[0125] In the SFN scheme for single DCI-based PUCCH, multiple (eg, two) TCI states may be applied to one PUCCH resource.

[0126] <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 7A). In multi-DCI-based STxMP, simultaneous transmission of UL channels / UL signals (e.g., PUSCH+PUSCH) may be supported (see Figure 7B). For example, two overlapping PUSCHs in the time domain are associated with different TRPs and transmitted simultaneously from different UE panels / beams.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] FIG. 8A shows an example of multi-DCI-based STxMP PUSCH+PUSCH, FIG. 8B shows an example of multi-DCI-based STxMP PUCCH+PUCCH, and FIG. 8C shows an example of multi-DCI-based STxMP PUCCH+PUSCH.

[0131] In STxMP PUSCH+PUSCH (see FIG. 8A), 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.

[0132] In STxMP PUCCH+PUCCH (see FIG. 8B), 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.

[0133] In STxMP PUCCH+PUSCH (see FIG. 8C), one PUCCH and one PUSCH are associated with different TRPs and transmitted simultaneously from the UE panel, and may be partially / fully overlapping in the time domain and partially / fully / non-overlapping in the frequency domain.

[0134] Prior to Rel. 17 (e.g., STxMP PUCCH+PUCCH in FIG. 8B and STxMP PUCCH+PUSCH in FIG. 8C are not supported), UE operations to resolve overlap between PUCCH and other UL channels / signals (e.g., PUCCH-PUCCH, PUCCH-PUSCH) were supported.

[0135] 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.).

[0136] (Transmission power control) <Transmission power control for PUSH> In NR (e.g., Rel. 16), the transmission power of PUSH is controlled based on the TPC command (also called a value, increase / decrease value, correction value, etc.) indicated by the value of a specified field (also called a TPC command field, etc.) in the DCI.

[0137] For example, when a UE transmits a PUSCH on an active UL BWP b of a carrier f of a serving cell c using a parameter set (open loop parameter set) with index j and a power control adjustment state index l, the transmission power (P ＰＵＳＣＨ、ｂ，ｆ，ｃ (i, j, q ｄ , l)) may be expressed by the following formula (1):

[0138]

[0139] Here, the power control adjustment state may be configured to have multiple states (e.g., two states) or a single state depending on a higher layer parameter. Furthermore, when multiple power control adjustment states are configured, one of the multiple power control adjustment states may be identified by an index l (e.g., l∈{0, 1}). The power control adjustment state may be referred to as a PUSCH power control adjustment state, a first or second state, etc.

[0140] Furthermore, the PUSCH transmission opportunity i is a predetermined period during which the PUSCH is transmitted, and may be composed of, for example, one or more symbols, one or more slots, etc.

[0141] In formula (1), P ＣＭＡＸ，ｆ，ｃ (i) is, for example, the transmit power of the user terminal (also referred to as maximum transmit power, UE maximum output power, etc.) set for carrier f of serving cell c at transmission opportunity i. Ｏ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ (j) is, for example, a parameter related to the target received power set for the active UL BWP b of the carrier f of the serving cell c in the parameter set setting j (e.g., a parameter related to the transmit power offset, also referred to as the transmit power offset P0, the target received power parameter, etc.).

[0142] M ＰＵＳＣＨ ＲＢ，ｂ，ｆ，ｃ(i) is the number of resource blocks (bandwidth) allocated to the PUSCH for transmission opportunity i in serving cell c and active UL BWP b of carrier f with subcarrier spacing μ, for example. ｂ，ｆ，ｃ (j) is a value provided by a higher layer parameter (e.g., also called msg3-Alpha, p0-PUSCH-Alpha, fractional factor, etc.).

[0143] PL ｂ，ｆ，ｃ (q ｄ ) is, for example, the index q of the reference signal (path loss reference RS, DL RS for path loss measurement, PUSCH-PathlossReferenceRS) for downlink BWP associated with the active UL BWP b of carrier f of serving cell c. ｄ is the path loss (path loss compensation) calculated by the user terminal using

[0144] Δ ＴＦ，ｂ，ｆ，ｃ (i) is the transmission power adjustment component (offset, transmission format compensation) for UL BWP b of carrier f of serving cell c.

[0145] f ｂ，ｆ，ｃ (i, l) is the TPC command-based value (e.g., power control adjustment state, accumulated value of TPC commands, closed-loop value) of the power control adjustment state index l of the active UL BWP of carrier f for serving cell c and transmission opportunity i, where l may be referred to as the closed-loop index.

[0146] If the UE is not provided with a path loss reference RS (e.g., PUSCH-PathlossReferenceRS) or if the UE is not provided with individual upper layer parameters, the UE may use RS resources from the SSB used to obtain the Master Information Block (MIB) to obtain the PL. ｂ，ｆ，ｃ (q ｄ ) may be calculated.

[0147] When the UE is configured with a number of RS resource indices up to the value of the maximum number of pathloss reference RSs (e.g., maxNrofPUSCH-PathlossReferenceRS) and a set of RS configurations for the RS resource indices according to the pathloss reference RSs, the set of RS resource indices may include one or both of a set of SS / PBCH block indices and a set of CSI-RS resource indices. ｄ may be identified.

[0148] If a PUSCH transmission is scheduled by a Random Access Response (RAR) UL grant, the UE uses the same RS resource index q as for the corresponding PRACH transmission. ｄ may also be used.

[0149] When a UE is provided with a power control configuration for the PUSCH by a sounding reference signal (SRS) resource indicator (SRI) (e.g., SRI-PUSCH-PowerControl) and one or more values ​​of ID of the pathloss reference RS, the UE may obtain a mapping between a set of values ​​for the SRI field in DCI format 0_1 ​​and a set of ID values ​​of the pathloss reference RS from higher layer signaling (e.g., sri-PUSCH-PowerControl-Id in SRI-PUSCH-PowerControl). The UE may obtain the RS resource index q from the ID of the pathloss reference RS mapped to the SRI field value in DCI format 0_1 ​​that schedules the PUSCH. ｄ may be determined.

[0150] If a PUSCH transmission is scheduled by DCI format 0_0 and the UE is not provided with PUCCH spatial relationship information for the PUCCH resource with the lowest index for the active UL BWP b of each carrier f and serving cell c, the UE shall transmit the PUCCH spatial relationship information for the PUCCH resource with the same RS resource index q as the PUCCH transmission in that PUCCH resource. ｄmay also be used.

[0151] If the PUSCH transmission is scheduled by DCI format 0_0 and the UE is not provided with a spatial setting for the PUCCH transmission, or if the PUSCH transmission is scheduled by DCI format 0_1 ​​that does not include an SRI field, or if the UE is not provided with a power control setting for the PUSCH by the SRI, the UE shall select an RS resource index q with an ID of a path loss reference RS of zero. ｄ may also be used.

[0152] For PUSCH transmission configured by a configured grant configuration (e.g., ConfiguredGrantConfig), if the configured grant configuration includes a predetermined parameter (e.g., rrc-ConfiguredUplinkGrant), the RS resource index q is determined by a path loss reference index (e.g., pathlossReferenceIndex) in the predetermined parameter. ｄ may be provided to the UE.

[0153] For the PUSCH transmission configured by the configuration grant configuration, if the configuration grant configuration does not include a predetermined parameter, the UE determines the RS resource index q from the value of the ID of the path loss reference RS mapped to the SRI field in the DCI format that activates the PUSCH transmission. ｄ If the DCI format does not include an SRI field, the UE may determine an RS resource index q with an ID of a pathloss reference RS of zero. ｄ may be determined.

[0154] <Transmission power control for PUCCH> In addition, in NR, the transmission power of PUCCH is controlled based on the TPC command (also called a value, an increase / decrease value, a correction value, an instruction value, etc.) indicated by the value of a predetermined field (also called a TPC command field, a first field, etc.) in DCI.

[0155] For example, the power control adjustment state index l is used to determine the PUCCH transmission power (P ＰＵＣＣＨ、ｂ，ｆ，ｃ (i, q ｕ , q ｄ , l)) may be expressed by the following formula (2).

[0156]

[0157] The power control adjustment state may also be referred to as a PUCCH power control adjustment state, a first or second state, and so on.

[0158] Furthermore, the PUCCH transmission opportunity i is a predetermined period during which the PUCCH is transmitted, and may be composed of, for example, one or more symbols, one or more slots, or the like.

[0159] In formula (2), P ＣＭＡＸ，ｆ，ｃ (i) is, for example, the transmit power of the user terminal (also referred to as maximum transmit power, UE maximum output power, etc.) set for carrier f of serving cell c at transmission opportunity i. Ｏ＿ＰＵＣＣＨ，ｂ，ｆ，ｃ (q ｕ ) is, for example, a parameter related to a target received power (e.g., a parameter related to a transmit power offset, also referred to as a transmit power offset P0 or a target received power parameter) set for an active UL BWP b of a carrier f of a serving cell c at a transmission opportunity i.

[0160] M ＰＵＣＣＨ ＲＢ，ｂ，ｆ，ｃ (i) is the number of resource blocks (bandwidth) allocated to PUCCH for transmission opportunity i in active UL BWP b of carrier f with serving cell c and subcarrier spacing μ, for example. ｂ，ｆ，ｃ (q ｄ) is, for example, the index q of the reference signal (path loss reference RS, DL RS for path loss measurement, PUCCH-PathlossReferenceRS) for downlink BWP associated with the active UL BWP b of carrier f of serving cell c. ｄ is the path loss calculated at the user terminal using

[0161] Δ Ｆ＿ＰＵＣＣＨ (F) is a higher layer parameter given for each PUCCH format. ＴＦ，ｂ，ｆ，ｃ (i) is the transmission power adjustment component (offset) for UL BWP b of carrier f of serving cell c.

[0162] g ｂ，ｆ，ｃ (i, l) is the TPC command-based value (e.g., power control adjustment state, accumulated value of TPC commands, closed-loop value, PUCCH power adjustment state) of the power control adjustment state index l of the active UL BWP of carrier f for serving cell c and transmission opportunity i.

[0163] If the UE is provided with information indicating the use of two PUCCH power control adjustment states (twoPUCCH-PC-AdjustmentStates) and PUCCH spatial relationship information (PUCCH-SpatialRelationInfo), l = {0, 1}; if the UE is not provided with information indicating the use of two PUCCH power control adjustment states or PUCCH spatial relationship information, l = 0.

[0164] If the UE obtains the TPC command value from DCI format 1_0 or 1_1, and if the UE is provided with PUCCH spatial relation information, the UE may obtain the mapping between the PUCCH spatial relation information ID (pucch-SpatialRelationInfoId) value and the closed-loop index (closedLoopIndex, power adjustment state index l) through the index provided by the P0 ID for PUCCH (p0-PUCCH-Id in p0-Set in PUCCH-PowerControl in PUCCH-Config). If the UE receives an activation command including a value of PUCCH spatial relation information ID, the UE may determine the value of the closed-loop index, which provides the value of l, through a link to the corresponding P0 ID for PUCCH.

[0165] If the UE has an active UL BWP b for carrier f of serving cell c, then P Ｏ＿ＰＵＣＣＨ，ｂ，ｆ，ｃ (q ｕ ) value setting is provided by a higher layer, ｂ，ｆ，ｃ (i, l) = 0, k = 0, 1, ..., i. If the UE is provided with PUCCH spatial related information, the UE ｕ , and the PUCCH spatial relationship information associated with q ｕ The value of l may be determined from the value of

[0166] q ｕ may be a P0 ID for PUCCH (p0-PUCCH-Id) indicating P0 for PUCCH (P0-PUCCH) in a P0 set for PUCCH (p0-Set).

[0167] <SRS Transmission Power Control> For example, using the index l of the power control adjustment state, the transmission power (P ＳＲＳ、ｂ，ｆ，ｃ (i, q ｓ , l) may be expressed by the following formula (3).

[0168] The power control adjustment state may be referred to as an SRS power control adjustment state, a value based on a TPC command, an accumulated value of a TPC command, a value by a closed loop, a first or second state, etc. 1 may be referred to as a closed loop index.

[0169] Furthermore, the SRS transmission opportunity i is a predetermined period during which the SRS is transmitted, and may be composed of, for example, one or more symbols, one or more slots, or the like.

[0170]

[0171] In formula (3), P ＣＭＡＸ，ｆ，ｃ (i) is, for example, the UE maximum output power for carrier f of serving cell c at SRS transmission opportunity i. P Ｏ＿ＳＲＳ，ｂ，ｆ，ｃ (q ｓ ) is the active UL BWP b of carrier f of serving cell c and the SRS resource set q ｓ (provided by SRS-ResourceSet and SRS-ResourceSetId), and a parameter related to the target received power provided by p0 for (for example, a parameter related to the transmit power offset, also referred to as the transmit power offset P0 or the target received power parameter, etc.).

[0172] M ＳＲＳ，ｂ，ｆ，ｃ (i) is the SRS bandwidth in number of resource blocks for SRS transmission opportunity i on active UL BWP b of carrier f of serving cell c and subcarrier spacing μ;

[0173] α ＳＲＳ，ｂ，ｆ，ｃ (q ｓ ) is the active UL BWP b of a serving cell c and carrier f with subcarrier spacing μ and an SRS resource set q ｓ and α (e.g., alpha) for

[0174] PL ｂ，ｆ，ｃ (q ｄ ) is the active DL BWP of serving cell c and the SRS resource set q ｓ and, for RS resource index q ｄ is the DL path loss estimate [dB] calculated by the UE using the RS resource index q ｄ is the SRS resource set q ｓ and a pathloss reference RS (a DL RS for pathloss measurement, e.g., provided by pathlossReferenceRS) associated with the SS / PBCH block index (e.g., ssb-Index) or a CSI-RS resource index (e.g., csi-RS-Index).

[0175] h ｂ，ｆ，ｃ (i, l) is the SRS power control adjustment state for the active UL BWP of carrier f of serving cell c and SRS transmission opportunity i. If the SRS power control adjustment state configuration (e.g., srs-PowerControlAdjustmentStates) indicates the same power control adjustment state for SRS transmission and PUSCH transmission, h ｂ，ｆ，ｃ (i, l) is the current PUSCH power control adjustment state f ｂ，ｆ，ｃ Same as (i, l).

[0176] The transmission opportunity i for PUSCH, PUCCH, and SRS is the slot index n within the frame of system frame number SFN. ｓ，ｆ μ , the first symbol S in the slot, and the number of consecutive symbols L. In the case of a PUSCH transmission of repetition type B, the transmission opportunity for the PUSCH may be a nominal repetition.

[0177] (Power Requirements) NR addresses the issue of Maximum Permitted Exposure (MPE) (or electromagnetic power density exposure). UEs are required to meet Federal Communication Commission (FCC) regulations on maximum radiation to the human body for health and safety reasons.

[0178] For example, in Rel. 15 NR, restrictions using power-management maximum power reduction (P-MPR / PMPR) are specified to limit exposure. For example, in the case of non-carrier aggregation (CA), the UE maximum output power P CMAX,f,c is the corresponding P UMAX,f,c The (measured maximum output power, measured set maximum UE output power) is set so as to satisfy the following equation (4).

[0179]

[0180] EIRP max Let P-MPR be the maximum value of the corresponding measured Peak Effective Isotropic Radiated Power (EIRP). f,c Let P-MPR be a value that indicates the maximum output power reduction allowed for carrier f of serving cell c. f,c is the configured UE maximum output power P CMAX,f,c The corresponding total radiated power P TMAX,f,c is P TMAX,f,c ≦TRP max This becomes:

[0181] In the case of carrier aggregation (CA), the UE maximum output power P CMAX,f,c is the corresponding P UMAX,f,c is set so as to satisfy the following equation (5).

[0182]

[0183] Measured P for Carrier Aggregation UMAX is P UMAX =Σ c,f(c) P UMAX,f,c where P UMAX,f,c is the measured power P for carrier f = f(c) of serving cell c UMAX,f,c The measured total radiated power of the carrier aggregation, P TMAX is P TMAX =10log 10 Σ c,f(c) P TMAX,f,c where P TMAX is the total radiated power P for carrier f = f(c) of serving cell c TMAX,f,c is the linear value of the measured total radiated power P TMAX is P TMAX ≦TRP max The boundary is defined as follows.

[0184] That is, the UE must calculate the measured peak EIRP (P UMAX ) is within the lower and upper limits, and the measured total radiated power P TMAX P TMAX ≦TRP ma The maximum output power is P CMAX It can be set as:

[0185] (PHR) In future wireless communication systems (e.g., NR), a UE will transmit a Power Headroom Report (PHR) to the network, including information on the power headroom (PH) for each serving cell. The network can use the PHR to control the uplink transmission power of the UE.

[0186] If M-TRP PUSCH is supported / configured / enabled and reporting of two PHRs for two TRPs is configured / enabled, it is considered to include two PHRs (first PHR and second PHR) in the PHR MAC CE. Reporting of two PHRs for two TRPs may be configured for the UE by higher layer parameters (RRC parameters).

[0187] Here, the first PHR may be reported as in Rel. 15 / 16. The second PHR may be a PHR for a different TRP than the first PHR. The second PHR may be reported as an actual PHR or a virtual PHR.

[0188] The actual PHR is a PHR based on an actual PUSCH transmission and may be referred to as a real PHR. The actual PHR may be calculated based on a power control parameter for the actual PUSCH transmission.

[0189] The virtual PHR is a PHR that does not depend on the actual PUSCH transmission (based on the reference PUSCH transmission) and may be referred to as a reference PHR, a PHR according to a reference format, etc. The virtual PHR may be calculated based on the default power control parameters already specified in Rel. 15 / 16 NR, or may be calculated based on new default power control parameters.

[0190] If the UE determines that the Type 1 power headroom report of the active serving cell is based on the actual PUSCH transmission, for a PUSCH transmission opportunity i on the active UL BWP b of carrier f of serving cell c, the UE calculates the Type 1 power headroom report as follows: The PHR in Equation (6) may be referred to as the actual PHR.

[0191]

[0192] If the UE determines that the Type 1 power headroom report of the active serving cell is based on the reference PUSCH transmission, for PUSCH transmission opportunity i on active UL BWP b of carrier f of serving cell c, the UE calculates the Type 1 power headroom report as follows: The PHR in Equation (7) may be referred to as the virtual PHR.

[0193]

[0194] Here, P ＣＭＡＸ，ｆ，ｃ (i) Bar (P ＣＭＡＸ，ｆ，ｃ (i) with ~ above the P) is MPR = 0 dB, A-MPR = 0 dB, P-MPR = 0 dB, ΔT Ｃ = 0 dB. A-MPR means Additional MPR. For the remaining parameters, P Ｏ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ (j) and α ｂ，ｆ，ｃ (j) is P Ｏ＿ＮＯＭＩＮＡＬ＿ＰＵＳＣＨ，ｆ，ｃ (0), p0-PUSCH-AlphaSetId=0 is used, and PL ｂ，ｆ，ｃ (q ｄ ) uses pusch-PathlossReferenceRS-Id=0, l=0.

[0195] (Maximum transmission power) Maximum transmission power (maximum transmission power) P of carrier f of serving cell c on panel p ＣＭＡＸｐａｎｅｌ，ｆ，ｃ，ｐ An example of setting P will be explained. ＣＭＡＸｐａｎｅｌ，ｆ，ｃ，ｐ Is, P ＣＭＡＸ，ｆ，ｃ，ｐ ) may also be written as

[0196] Option 0: The UE may receive a configuration (e.g., a configuration similar to that of Rel. 17) regarding the maximum transmission power for each serving cell and each carrier, and may determine the maximum transmission power for each panel based on the configuration. For example, the UE may determine that the maximum transmission power of carrier f of serving cell c is P ＣＭＡＸ，ｆ，ｃ and the maximum transmission power P ＣＭＡＸ，ｆ，ｃ，ｐ The P ＣＭＡＸ，ｆ，ｃ or P ＣＭＡＸ，ｆ，ｃ and P ＣＭＡＸ，ｆ，ｃ，ｐThe P ＣＭＡＸ，ｆ，ｃ , and the relationship may be set in the UE by higher layer signaling / physical layer signaling. In this case, the maximum transmission power for each panel may be exemplified as follows:

[0197] Option 0-1: The UE determines the maximum transmission power P of panel p based on the following equation (8): ＣＭＡＸ，ｆ，ｃ，ｐ where N is the number of panels instructed to transmit simultaneously, i.e., the maximum transmission power of each panel may be the same.

[0198]

[0199] For example, N may be 2 when simultaneous multi-panel transmission is instructed. N may be 1 when single-panel transmission is instructed. Alternatively, N may be determined based on at least one of a value set by the network (base station) through higher layer signaling / physical layer signaling and UE capabilities. Different values ​​may be applied to single-panel transmission and multi-panel transmission. Alternatively, N may be the maximum number of panels supported by the UE in UL transmission (e.g., N=2), and the application of single-panel transmission or simultaneous multi-panel transmission may not be instructed by the network.

[0200] Option 0-2: The UE determines the maximum transmission power P of panel p based on the following equation (9): ＣＭＡＸ，ｆ，ｃ，ｐ may be determined. That is, the sum of the maximum transmission powers of the panels p may be the maximum transmission power of the UE. Np is a value for panel p and may be different for each panel. That is, the maximum transmission power of each panel may be different.

[0201]

[0202] Np may be determined based on at least one of a value set by higher layer signaling / physical layer signaling from the network (base station) and UE capability, and may have different values ​​for single-panel transmission and multi-panel transmission.

[0203] Option 0-3: The UE determines the maximum transmission power P of panel p based on the following equation (10): ＣＭＡＸ，ｆ，ｃ，ｐ In other words, the maximum transmission power of the UE may be the sum of the maximum transmission powers of the panels p. In this case, the maximum transmission powers of the panels p may be the same or different, or some of the panels may have the same maximum transmission power.

[0204]

[0205] This clarifies the maximum transmission power of panel p, the maximum transmission power of all panels, and the relationship between them, allowing the UE to control simultaneous UL transmission of multiple panels using appropriate transmission power.

[0206] (Reporting of M-TRP PHR in Rel. 17) If a PHR MAC CE is reported in slot n for an M-TRP PUSCH repetition in Rel. 17, the first PHR for the first TRP is reported in the same manner as in Rel. 16. The second PHR for the second TRP may be defined as follows: (1) If the first PHR is the actual PHR and the PUSCH repetition associated with the second TRP is in slot n, the second PHR is the actual PHR. (2) If the first PHR is the actual PHR and the PUSCH repetition associated with the second TRP is not in slot n, the second PHR is the virtual PHR. (3) If the first PHR is the virtual PHR, the second PHR is the virtual PHR.

[0207] The virtual PHR may be calculated using the default power control parameters (p0, alpha (α), PL-RS, closed loop index) for each TRP.

[0208] When the UE is provided with twoPHRMode in the active UL BWP b of carrier f of serving cell c and with two SRS resource sets whose usage is set to "codebook" or "non-codebook" in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2, the UE shall provide the following two types of first power headroom reports (1) and (2). In (1) and (2), it is assumed that the UE provides a first Type 1 PHR for the actual PUSCH repetition of the earliest PUSCH transmission in a slot associated with one SRS resource set.

[0209] (1) If the UE transmits a PUSCH repetition associated with another SRS resource set in slot n, then the UE provides a second Type 1 power headroom report for the first actual PUSCH repetition associated with the other SRS resource set that overlaps with slot n. (2) Otherwise (if condition (1) is not met), the UE provides a second Type 1 power headroom report for the reference PUSCH transmission associated with the other SRS resource set.

[0210] (UE Capabilities, etc.) In this disclosure, a "panel" may refer to a value (or set of values) of UE capabilities, as in Rel. 17. Also, a "panel" may refer to an equivalent definition of other terms, such as a "UE antenna group."

[0211] The beam may indicate spatial relations / TCI / Spatial Relation Information (SRI). The TRP may refer to the CORESETPool / SRS resource set.

[0212] In simultaneous multi-panel transmission (STxMP), the following schemes may be applied: Single DCI (S-DCI) Space Division Multiplexing (SDM) scheme: Different layers / DMRS ports of one PUSCH are separately precoded and transmitted simultaneously from different UE beams / panels. S-DCI Frequency Division Multiplexing (FDM)-A scheme: Different parts of the frequency domain resources of one PUSCH transmission opportunity are transmitted from different UE beams / panels. S-DCI FDM-B scheme: Two PUSCH transmission opportunities of the same / different RV of the same TB are transmitted from different UE beams / panels on non-overlapping frequency domain resources and the same time domain resources. S-DCI SFN-based transmission scheme: The same PUSCH / DMRS is transmitted simultaneously from two different UE beams / panels. S-DCI spatial domain repetition scheme: Two PUSCH transmission opportunities with different redundancy versions (RV) of the same TB are transmitted from two different UE beams / panels on the same time and frequency resources. M-DCI scheme: Two overlapping (fully / partially overlapping in the time domain, fully / partially overlapping or non-overlapping in the frequency domain) PUSCHs are transmitted from two different UE beams / panels.

[0213] Simultaneous multi-panel transmission assumes multi-TPR, and one panel corresponds to one TRP. Therefore, in this disclosure, the PUSCH associated with a panel can also be referred to as the PUSCH associated with a TRP, and the PHR / power of a panel can also be referred to as the PHR / power of a TRP.

[0214] In the present disclosure, it is considered that a UE receives PUSCH / SRS in one panel and PUCCH / SRS in time resources that completely / partially overlap with PUSCH reception in another panel (simultaneous multi-panel reception).

[0215] The "single panel transmission" in this disclosure may be applied only when there is a PUSCH transmission with a single panel and no PUCCH / SRS transmission in other panels on time resources that fully / partially overlap with the PUSCH transmission. Note that in this case, how to handle PHR reporting needs further consideration, e.g., in the case of PUSCH+SRS, reporting one Type 1 PHR based on PUSCH and one Type 3 PHR based on SRS.

[0216] Alternatively, the term "single panel transmission" in the present disclosure may also apply to a case where there is a PUSH transmission with a single panel and there is a PUCCCH / SRS transmission with another panel in a time resource that completely / partially overlaps with the PUSH transmission.

[0217] (Assumptions for simultaneous UL transmission over multiple panels) In the case of simultaneous UL transmission over multiple panels, taking into consideration the limitations on the maximum UL transmission power, at least one of the following assumptions 1-1 to 1-3 is assumed.

[0218] [Assumption 1-1] Consider the maximum UL transmission power for each panel. It is assumed that the actual transmission power of PUSCH / PUCCH / SRS of panel p in serving cell c is equal to or less than the maximum UL transmission power of panel p in serving cell c. That is, P panel_actual,c,p ≦P panel_max,c,p The maximum UL transmission power of panel p in serving cell c may be calculated using any of the above (maximum transmission power) equations (8) to (10). Note that if the carrier is not specified, the element of carrier f may be removed.

[0219] P panel_actual,c,p is the actual transmission power of serving cell c, panel p, and P panel_max,c,p is the maximum UL transmit power of serving cell c, panel p.

[0220] [Assumption 1-2] Consider the maximum UL transmission power for each cell. It is assumed that the total of the actual transmission power of PUSCH / PUCCH / SRS from multiple panels of serving cell c is equal to or less than the maximum UL transmission power of serving cell c. That is, Σ p Ppanel_actual,c,p ≦P cell_max,c The maximum UL transmission power of the serving cell c is the value determined in Rel. 17 (i.e., P ＣＭＡＸ,ｆ,ｃ ) is also acceptable. panel_actual,c,p is the actual transmission power of panel p in serving cell c, P cell_max,c is the maximum UL transmit power of serving cell c.

[0221] [Assumptions 1-3] Both the maximum UL transmission power per panel and the maximum transmission power per cell may be considered. The transmission power may satisfy the conditions of both Assumptions 1 and 2.

[0222] (Assumptions for Single-Panel UL Transmission) When dynamic switching between single-panel transmission and simultaneous multi-panel transmission is supported, at least one of the following assumptions 2-1 and 2-2 is assumed, taking into account the limit on maximum UL transmission power.

[0223] [Assumption 2-1] Consider the maximum UL transmission power for each panel. It is assumed that the actual transmission power of PUSCH / PUCCH / SRS in single-panel transmission in panel p in serving cell c is equal to or less than the maximum UL transmission power of panel p in serving cell c. That is, P panel_actual,c,p ≦P panel_max,c,p holds true.

[0224] P panel_actual,c,p is the actual transmission power of serving cell c, panel p, and P panel_max,c,p is the maximum UL transmit power of serving cell c, panel p.

[0225] [Assumption 2-2] Consider the maximum UL transmission power for each cell. It is assumed that the total actual transmission power of PUSCH / PUCCH / SRS from the single panel of serving cell c is equal to or less than the maximum UL transmission power of serving cell c. That is, P panel_actual,c,p ≦P cell_max,c The maximum UL transmission power of the serving cell c is the value determined in Rel. 17 (i.e., P ＣＭＡＸ,ｆ,ｃ ) is also acceptable.

[0226] P panel_actual,c,pis the actual transmit power of panel p in serving cell c, and P cell_max,c is the maximum UL transmit power of serving cell c.

[0227] In the case of single panel transmission, panel_max,c,p , P cell_max,c If the same, then Assumption 2-1 and Assumption 2-2 are the same.

[0228] (PHR Triggering) In existing specifications (e.g., Rel. 17), PHR may be triggered based on at least one of the following events / conditions: - When the PHR prohibition timer (phr-ProhibitTimer) expires (expires) / has expired, and the MAC entity has UL resources for a new transmission, and the path loss has changed by more than a predefined threshold (phr-Tx-PowerFactorChange (dB)) for at least one reference signal used as a path loss reference for one activated serving cell (activated Serving Cell) corresponding to any MAC entity whose active DL BWP is not a dormant BWP since the last PHR transmission at that MAC entity. - When the PHR periodic timer (phr-PeriodicTimer) expires. - When the PHR functionality is configured / reconfigured by higher layer signaling (note that such higher layer signaling does not need to be used to disable the PHR functionality). - When an SCell corresponding to a UL-configured MAC entity whose firstActiveDownlinkBWP-Id is not set to dormant BWP is activated. - When an SCG is activated. - When a PSCell is added (i.e., when a PSCell is newly added / modified) except when an SCG is deactivated. - When the PHR prohibit timer (phr-ProhibitTimer) expires / has expired and the MAC entity has UL resources for new transmissions and the following is true for an activated serving cell corresponding to any UL-configured MAC entity:- When there are UL resources allocated for transmission / PUCCH transmission in this cell (the activated serving cell) and the requested power back-off for power management for this cell has changed by more than a predetermined threshold (phr-Tx-PowerFactorChange (dB)) since the last PHR transmission. - When an SCell corresponding to any MAC entity with UL configured switches from an activated dormant BWP to a non-dormant BWP. - When the higher layer parameter mpe-Reporting-FR2 is configured and the MPE prohibit timer (mpe-ProhibitTimer) is not running. - When, since the last PHR transmission in a MAC entity, the measured PMPR applied to meet the FR2 MPE requirements is equal to or greater than a predetermined threshold (mpe-Threshold) for at least one active FR2 serving cell. - If the PMPR measurement applied to meet the FR2 MPE requirement has changed by more than a predefined threshold (phr-Tx-PowerFactorChange (dB)) for at least one active FR2 serving cell since the last PHR transmission at a MAC entity, in which case the PHR may be referred to as an "MPE P-MPR report".

[0229] (Type 1 PH Report) If a UE is provided with two PHR modes (twoPHRMode) and two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with codebook / non-codebook as usage in an active UL BWP b of carrier f of serving cell c, the UE shall provide two Type 1 power headroom reports in slot n.

[0230] where: if the UE provides a first Type 1 power headroom report for the actual PUSCH repetition of the earliest disclosed PUSCH transmission in slot n associated with one SRS resource set, and if the UE transmits a PUSCH repetition associated with another SRS resource set in slot n, then the UE provides a second Type 1 power headroom report for the first actual PUSCH repetition associated with the other SRS resource set that overlaps with slot n.

[0231] Otherwise, the UE provides a second Type 1 power headroom report for the reference PUSCH transmission associated with the other SRS resource set.

[0232] Here, when the UE is provided with a dl-OrJointTCI-StateList or an UL TCI state (TCI-UL-State) and is indicated a first TCI state / UL TCI state and a second TCI state / UL TCI state, the UE provides a second Type 1 power headroom report using the value of p0AlphaSetforPUSCH and the value of pathlossReferenceRS-Id-r17 associated with the first TCI state / UL TCI state.

[0233] For an active UL BWP b of carrier f of serving cell c, the UE is provided with: two PHR modes (twoPHRMode); two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with codebook / non-codebook as usage; a dl-OrJointTCI-StateList or UL TCI-state (TCI-UL-State) is provided indicating the first TCI-state / UL TCI-state and the second TCI-state / UL TCI-state; if a multipanelScheme is provided, the UE may provide at least one of the following:

[0234] a Type 1 power headroom report associated with the first TCI state / UL TCI state and a configured maximum output power for an actual PUSCH transmission using a spatial domain filter corresponding only to the first TCI state / UL TCI state; a Type 1 power headroom report associated with the second TCI state / UL TCI state and a configured maximum output power for an actual PUSCH transmission using a spatial domain filter corresponding only to the second TCI state / UL TCI state; a Type 1 power headroom report associated with the first TCI state / UL TCI state and a configured maximum output power for an actual PUSCH transmission using a spatial domain filter corresponding to the first TCI state / UL TCI state and using a spatial domain filter corresponding to the second TCI state / UL TCI state, and a Type 1 power headroom report associated with the second TCI state / UL TCI state and a configured maximum output power.

[0235] (Analysis) Meanwhile, PHR for multiple TRP repetition in Rel. 17 when the unified TCI framework is applied has been considered. For example, when a UE provides PHR for a reference PUSCH transmission associated with the first / second SRS resource set (first / second TCI state), the UE uses the values ​​of p0AlphaSetforPUSCH and pathlossReferenceRS-Id-r17 associated with the first / second TCI state.

[0236] If the UE is instructed to use two TCI states, the PHR functionality described above needs to be extended in the following cases: - When the UE is provided with two PHR modes (twoPHRMode) in STxMP with a single DCI PUSCH SDM / SFN scheme - When the UE is provided with two PHR modes (twoPHRMode) in STxMP with a multi-DCI (overlapping) PUSCH+PUSCH scheme.

[0237] In other words, the PHR regulations should be further expanded depending on the type of simultaneous multi-panel transmission.

[0238] In particular, it is not clear whether PHR (whether two PHR modes are supported) is supported in the case of multi-DCI-based STxMP PUSCH+PUSCH (PUSCH repetition).

[0239] Thus, if the regulations (control methods) regarding PHR are not clear, transmission control may not be performed appropriately, which may result in a decrease in communication throughput.

[0240] Therefore, the present inventors have conceived a method for controlling PHR according to the applied scenario.

[0241] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Wireless communication methods according to the embodiments may be applied independently or in combination.

[0268] First Embodiment The first embodiment relates to a power headroom report (PHR) for multi-DCI-based simultaneous multi-panel (STxMP) PUSCH repeated transmission.

[0269] When multi-DCI-based STxMP PUSCH repeated transmission is enabled, the UE may control the reporting of PHR depending on whether two PHR modes (twoPHRMode) are supported (configured or not).

[0270] The UE may determine whether to report one or two PHRs based on the configuration of the two PHR mode (twoPHRMode). In other words, the UE may control the number of PHRs to be reported based on the type of PHR mode supported. For example, if the two PHR mode (twoPHRMode) is configured, the UE may report two (first / second) PHRs. Alternatively, if the two PHR mode (twoPHRMode) is not configured, the UE may report one specific PHR.

[0271] Specifically, the UE may control the reporting of PHR according to at least one of options 1 and 2 below.

[0272] [Option 1] Option 1 describes a case where two PHR modes are supported in multi-DCI-based STxMP PUSCH repetitive transmission.

[0278] <Case where multi-DCI based STxMP (sTx-2Panel) is configured> For an active UL BWP b of carrier f of serving cell c, the UE is provided with: - two PHR modes (twoPHRMode); - two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with codebook / non-codebook set as usage; - a dl-OrJointTCI-StateList or UL TCI state (TCI-UL-State) is provided indicating the first TCI state / UL TCI state and the second TCI state / UL TCI state; - when multi-DCI based STxMP (sTx-2Panel) is provided, the UE may provide / report / send at least one of Alt1 to Alt4 below.

[0283] According to Option 1, when a multi-panel scheme (multipanelScheme) or a multi-DCI based STxMP (sTx-2Panel) is configured and two PHR modes (twoPHRMode) are configured, the UE can report two (first / second) PHRs.

[0284] [Option 2] Option 2 describes a case where two PHR modes are not supported in multi-DCI-based STxMP PUSCH repetitive transmission.

[0285] When multi-DCI-based STxMP PUSCH repeated transmission is enabled, if two PUSCH transmissions overlap in time, the UE is not clear which PUSCH the PHR should be transmitted for. Therefore, the following is proposed.

[0286] If multi-DCI based STxMP PUSCH repeated transmission is enabled, the UE may provide / report / transmit the actual PHR of the PUSCH associated with a CORESET pool index of value 0.

[0287] Specifically, if a UE is not provided with two PHR modes (twoPHRMode) and is provided with two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with codebook / non-codebook as usage in active UL BWP b of carrier f of serving cell c, the UE may provide / report / transmit one Type 1 power headroom report in slot n.

[0288] If the type 1 power headroom report is a PHR for an actual PUSCH repetition, the type 1 power headroom report is a PHR for the first PUSCH repetition associated with the first / second SRS resource set that overlaps with slot n.

[0289] If a UE is provided with two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with codebook / non-codebook set as usage and is provided with multi-DCI based STxMP (sTx-2Panel) in active UL BWP b of carrier f of serving cell c, and if two PUSCH transmissions associated with two different CORESET pool index values ​​overlap in time, the UE may provide / report / send a Type 1 power headroom report for the actual PUSCH transmission associated with CORESET pool index value 0.

[0290] According to option 2, if two PHR mode (twoPHRMode) is not configured, the UE can report one PHR corresponding to a specific PUSCH (associated with a CORESET pool index of value 0).

[0291] According to this embodiment, when multi-DCI-based STxMP PUSCH repeated transmission is enabled, the UE can appropriately control PHR reporting depending on whether two PHR modes (twoPHRMode) are supported.

[0306] (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.

[0307] 9 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).

[0308] 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.

[0309] 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.

[0310] 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))).

[0311] 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 location, number, shape, size, etc. of each cell and user terminal 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 the base station 10.

[0312] The wireless communication system 1 may utilize multi-input multi-output (MIMO). For example, one cell may be formed by one antenna / base station 10, or may be formed by multiple antennas / base stations 10. One [virtual] cell (which may be called, for example, a supercell) may be composed of multiple [virtual] cells (which may be called, for example, subcells). A supercell may correspond to a cell with a fixed physical range, and a subcell may correspond to a cell with a quasi-static / dynamically variable physical range. In this case, the wireless communication system 1 may be called a cell-free system.

[0313] 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).

[0314] 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.

[0315] 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.

[0316] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 / Xn 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.

[0317] 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.

[0318] 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.

[0319] The user terminal 20 may be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0320] 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).

[0321] 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.

[0322] 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.

[0323] 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.

[0324] 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).

[0325] 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.

[0326] 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.

[0327] 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.

[0328] 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.

[0329] 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.

[0330] In the present disclosure, downlink, uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning.

[0331] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, as the DL-RS, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted.

[0332] The synchronization signal may be, for example, at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). A signal block including an SS (PSS, SSS) and a PBCH (and a DMRS for the PBCH) may be referred to as an SS / PBCH block, an SS Block (SSB), or the like. Note that the SS, SSB, and the like may also be referred to as a reference signal.

[0333] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), or the like may be transmitted as an uplink reference signal (UL-RS). Note that the DMRS may also be called a user equipment-specific reference signal (UE-specific reference signal).

[0334] (Base Station) Fig. 10 is a diagram showing an example of the configuration of a base station according to an embodiment. The base station 10 includes a control unit 110, a transceiver unit 120, a transceiver antenna 130, and a transmission line interface 140. Note that the base station may include one or more of each of the control unit 110, the transceiver unit 120, the transceiver antenna 130, and the transmission line interface 140.

[0335] In this example, the functional blocks of the characteristic parts of the present embodiment are mainly shown, and it may be assumed that the base station 10 also has other functional blocks necessary for wireless communication.

The control unit 110 may perform call processing (setting up, releasing, etc.) of communication channels, status management of the base station 10, management of radio resources, etc.

[0338] The transceiver unit 120 may include a baseband unit 121, a radio frequency (RF) unit 122, and a measurement unit 123. The baseband unit 121 may include a transmission processing unit 1211 and a reception processing unit 1212.

[0354] (User Terminal) Fig. 11 is a diagram showing an example of the configuration of a user terminal according to one embodiment. The user terminal 20 includes a control unit 210, a transceiver unit 220, and a transceiver antenna 230. Note that the user terminal 20 may include one or more of each of the control unit 210, the transceiver unit 220, and the transceiver antenna 230.

[0355] 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.

[0363] The transceiver unit 220 (transmission processing unit 2211) may perform PDCP layer processing, RLC layer processing (e.g., RLC retransmission control), MAC layer processing (e.g., HARQ retransmission control), etc. on data, control information, etc. obtained from the control unit 210, and generate a bit string to be transmitted.

[0364] The transmitter / receiver unit 220 (transmission processing unit 2211) may perform transmission processing such as channel coding (which may include error correction coding), modulation, mapping, filtering, DFT processing (if necessary), IFFT processing, precoding, and digital-to-analog conversion on the bit string to be transmitted, and output a baseband signal.

[0365] 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.

The measurement unit 223 may also derive interference measurements for CSI calculation based on the interference measurement resources. The interference measurement resources may be at least one of an NZP CSI-RS resource for interference measurement, a CSI-Interference Measurement (IM) resource, etc. Note that CSI-IM may be referred to as CSI-Interference Management (IM) or may be interchangeably read as Zero Power (ZP) CSI-RS. Note that in the present disclosure, CSI-RS, NZP CSI-RS, ZP CSI-RS, CSI-IM, CSI-SSB, etc. may be interchangeably read as interchangeable.

[0371] 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.

When provided with parameters enabling a multi-panel scheme or multi-DCI-based STxMP and parameters enabling two PHRs, the controller 210 may control the transmission of two Type 1 PHRs. When provided with parameters enabling a multi-panel scheme or multi-DCI-based STxMP and parameters enabling two PHRs, the controller 210 may control the transmission of the PHRs based on whether two PUSCH transmissions overlap in time. If a parameter enabling two PHRs is not provided, the control unit 210 may control to transmit one Type 1 PHR for a PUSCH transmission associated with a particular control resource set (CORESET) pool index value.

[0373] (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.

For example, a functional block (component) that performs transmission may be called a transmitting unit, transmitter, etc. As described above, the implementation method of each is not particularly limited.

[0375] For example, a base station, a user terminal, or the like 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. 12 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, and the like.

[0376] 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.

[0377] 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.

[0378] 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.

[0379] 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.

[0380] 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.

[0381] 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.

[0382] 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.

[0383] 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.

[0384] 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).

[0385] 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.

[0386] 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.

[0387] In addition, the devices included in the core network 30 (for example, network nodes that provide NF) may also be realized by the above-mentioned functional block / hardware configuration.

[0388] (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.

[0389] 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.

[0390] 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.

[0391] 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.

[0392] 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.

[0393] 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.

[0394] 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.

[0395] 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.

[0396] 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.

[0397] 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.

[0398] 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.

[0399] 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.

[0400] 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. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0401] In addition, an RB may include one or more symbols in the time domain and may have a length of one slot, one minislot, one subframe, or one TTI, each of which may be composed of one or more resource blocks.

[0402] In addition, one or more RBs may be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0403] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0404] A Bandwidth Part (BWP), which may also be referred to as a partial bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0405] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0406] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0407] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0408] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

[0409] The names used for parameters and the like in this disclosure are not intended to be limiting in any way. Furthermore, the mathematical expressions and the like using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

Input and output information, signals, etc. may be overwritten, updated, or added. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

Furthermore, the MAC signaling may be notified using, for example, a MAC Control Element (CE).

[0416] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0417] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value represented by true or false, or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).

[0419] Software, instructions, information, etc. may also be transmitted or received over a transmission medium. For example, if software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL)), and / or wireless technologies (such as infrared, microwave), these wired and / or wireless technologies are included within the definition of transmission media.
