Description

Terminal, wireless communication method and base station The present disclosure relates to a terminal, a wireless communication method, and a base station in a next-generation mobile communication system. Long Term Evolution (LTE) has been specified for the purpose of achieving higher data rates and lower latency in Universal Mobile Telecommunications System (UMTS) networks (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified for the purpose of achieving higher capacity and greater sophistication of LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9). 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. 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 In future wireless communication systems (e.g., NR), it is considered that channel state information (CSI) based on reception of a reference signal will be reported. In addition, it is considered that multiple transmission / reception points (TRPs, Multi TRP (MTRP)) or multiple panels (multiple panels, multi-panel) will perform DL transmission to a terminal (user terminal, User Equipment (UE)). In addition, coherent joint transmission (CJT) using multi-TRP / multi-panel is being considered. However, when DL channels / signals (e.g., PDSCH / CSI measurement resources, etc.) that apply / support CJT are supported, there has been no sufficient consideration as to how to configure the channels / signals, etc. Therefore, one of the objectives of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can perform communication appropriately even when CJT is applied / supported to a DL channel / signal. A terminal according to one aspect of the present disclosure includes a receiving unit that receives information regarding the configuration of at least one channel state information reference signal (CSI-RS) resource for channel measurement of coherent joint transmission (CJT), and a control unit that, when receiving a downlink shared channel (PDSCH) corresponding to CJT, determines quasi-co-location of the PDSCH and the CSI-RS resource based on at least one of the number of transmission configuration indicators (TCIs) for the PDSCH, the number of the CSI-RS resources, and the number of TCI states corresponding to the CSI-RS. According to one aspect of the present disclosure, communication can be performed appropriately even when CJT is applied / supported to DL channels / signals. 1A-1D are diagrams showing an example of association of CMR and TCI state.

FIG. 8 is a diagram showing an example of a vehicle according to an embodiment. (TCI, spatial relations, 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). The TCI state may represent that which is applied to a downlink signal / channel, and the equivalent of the TCI state which is applied to an uplink signal / channel may be expressed as a spatial relation. 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 on a per-channel or per-signal basis. The QCL is an index indicating a statistical property of a signal / channel. For example, when a signal / channel has a QCL relationship with another signal / channel, it may mean that it can be assumed that at least one of the following parameters is the same (QCL with respect to at least one of them) among the Doppler shift, Doppler spread, average delay, delay spread, and spatial parameter (e.g., spatial Rx parameter) between these different signals / channels. In addition, the spatial reception parameters may correspond to a reception beam (e.g., a reception analog beam) of the UE, and the beam may be specified based on a spatial QCL. The QCL (or at least one element of the QCL) in the present disclosure may be read as a spatial QCL (sQCL). A plurality of types of QCLs (QCL types) may be defined. For example, four QCL types A to D may be provided, each of which has different parameters (or parameter sets) that can be assumed to be the same. The UE's assumption that a Control Resource Set (CORESET), channel, or reference signal is in a particular QCL (e.g., QCL type D) relationship with another CORESET, channel, or reference signal may be referred to as a QCL assumption. 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. 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 of both. The physical layer signaling may be, for example, Downlink Control Information (DCI). 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)). In addition, 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). The 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). The SSB may be referred to as an SS / PBCH block. 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 (its DMRS), and this RS may be called a QCL source of QCL type X in the TCI state. In the present disclosure, the following may be read interchangeably: a port (antenna port) of a signal (resource, channel) is QCLed with an RS (DL RS, QCL source RS), there is a QCL relationship between a port of a signal and an RS, a signal is QCLed with an RS, a signal is QCLed with an RS in a TCI state, a signal is QCLed with an RS in a TCI state for a specific QCL type, a signal is associated with a TCI state, a TCI state is set / indicated for a signal, and a UE assumes that a port of a signal is QCLed with an RS in a TCI state. In the present disclosure, beam, SD beam, spatial domain index, precoding, precoder, quasi co-location (QCL) assumption, QCL relationship, transmission configuration indicator (TCI) state, spatial domain filter, spatial domain receive filter, spatial domain transmit filter, reference signal (RS), and spatial receive parameters may be interpreted as interchangeable. (Unified / Common TCI Framework) According to the unified TCI framework, multiple types of (UL / DL) channels / RSs can be controlled by a common framework. The unified TCI framework does not specify the TCI state or spatial relationship for each channel as in Rel. 15, but instead specifies a common beam (common TCI state) and may apply it to all UL and DL channels, or a common beam for UL may apply to all UL channels and a common beam for DL ​​may apply to all DL channels. One common beam for both DL and UL, or one common beam for DL ​​and one common beam for UL (total of two common beams) are considered. 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 respectively (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). UL and DL default beams may be aligned via MAC CE based beam management (MAC CE level beam indication). Default TCI state of PDSCH may be updated to align with default UL beam (spatial relationship). DCI based beam management (DCI level beam indication) may indicate a common beam / unified TCI state from the same TCI pool (joint common TCI pool, joint TCI pool, set) for both UL and DL. X (>1) TCI states may be activated by the MAC CE. The UL / DL DCI may select one out of the X active TCI states. The selected TCI state may apply to both UL and DL channels / RS. The TCI pool (set) may be a plurality of TCI states set by the RRC parameters, or may be a plurality of TCI states (active TCI states, active TCI pools, sets) activated by the MAC CE among the plurality of TCI states set by the RRC parameters. Each TCI state may be a QCL type A / D RS. SSB, CSI-RS, or SRS may be set as the QCL type A / D RS. The number of TCI states corresponding to one or more TRPs may be specified. For example, the number N (≧1) of TCI states (UL TCI states) applied to UL channels / RSs and the number M (≧1) of TCI states (DL TCI states) applied to DL channels / RSs may be specified. At least one of N and M may be notified / configured / indicated to the UE via higher layer signaling / physical layer signaling. 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. For example, when N=M=1 is written, it 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). 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 state for a single TRP). Also, for example, when N=M=2 is written, it may mean that a TCI state common to multiple (two) ULs and DLs for multiple (two) TRPs is notified / configured / indicated to the UE (joint TCI state for multiple TRPs). 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). 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. It is being considered that N=M=1 will be supported in Rel. 17. For example, it may be supported to indicate one common beam (e.g., a common beam) by RRC / MAC CE / DCI, and the one common beam may be applied to multiple DL / UL channels / reference signals. Other cases may be supported in Rel. 18 and later. In a joint DL / UL TCI state, an RRC parameter (information element) configures multiple TCI states for both DL and UL. The MAC CE may activate multiple TCI states among the configured TCI states. The DCI may indicate one of the activated TCI states. The DCI may be a UL DCI (e.g., a DCI used to schedule a PUSCH) or a DL DCI (e.g., a DCI used to schedule a PDSCH). The indicated TCI state may apply to at least one (or all) of the UL / DL channels / RS. One DCI may indicate both UL and DL TCI. The indicated single TCI state ID may be one TCI state that applies to both UL and DL, or may be two TCI states that apply to UL and DL, respectively. At least one of the TCI states configured by the RRC parameters and the 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 TCI states activated by the MAC CE may be referred to as an active TCI pool (active common TCI pool). In the present disclosure, the 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 the multiple TCI states using DCI may be receiving indication information instructing one of the multiple TCI states included in DCI, or may simply be receiving "instruction information." In a separate TCI state (e.g., Separate TCI (DL TCI state and UL TCI state)), 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) among the configured multiple TCI states. Separate active TCI pools for each of the UL and DL may be configured / activated. The DL DCI, or the new DCI format, may select (indicate) one or more (e.g., one) TCI states. The selected TCI states may apply to one or more (or all) DL channels / RS. 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 the new DCI format, may select (indicate) one or more (e.g., one) TCI states. The selected TCI states may apply to one or more (or all) UL channels / RS. The UL channels may be PUSCH / SRS / PUCCH. Thus, different DCIs may indicate the UL TCI and DL DCI separately. It is assumed that in Rel. 17 NR and later, the MAC CE / DCI supports beam activation / indication to TCI states associated with different physical cell identifiers (PCIs), and in Rel. 18 NR and later, the MAC CE / DCI supports indication of serving cell change to a cell with a different PCI. The joint TCI state and the separate (DL / UL) TCI state may be switched for application. Whether the joint TCI state or the separate TCI state is applied may be set by a higher layer parameter from the base station to the UE, or may be switched by a TCI field (TCI state ID) in the DCI. The 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 In addition, the DCI in the above-mentioned mode 2 / mode 3 may be called a beam instruction DCI. In the present disclosure, the TCI state indicated by the DCI, the indicated TCI state, the indicated TCI state, the unified TCI state, the TCI state applied to multiple types of channels / signals, the joint TCI state (for DL ​​and UL), the DL TCI state, the UL TCI state, the Rel.17 TCI state, the common TCI state, the single unified TCI state to be configured, and the single unified TCI state to be activated may be read as interchangeable. In the present disclosure, the TCI state set by RRC parameters, the configured TCI state, the set TCI state, the TCI state that does not conform to the unified TCI state, the TCI state other than the unified TCI state, the TCI state / spatial relationship set for a particular channel / signal, and the individual TCI state may be interpreted as interchangeable. Unified / common TCI state may refer to the indicated TCI state indicated using DCI / MAC CE / RRC (in Rel. 17). The indicated TCI state may be shared with at least one of the UE-specific reception of PDSCH / PDCCH (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. If the indicated TCI state is supported (in Rel. 17), a TCI state other than the unified TCI state may mean a TCI state configured using MAC CE / RRC (configured TCI state) (in Rel. 17). The configured TCI state may not be shared with at least one of the UE-specific reception in PDSCH / PDCCH (updated using DCI / MAC CE / RRC of Rel. 17), PUSCH of dynamic grant (DCI) / configured grant, and multiple (e.g., all) dedicated PUCCH resources. The configured TCI state may be configured by RRC / MAC CE for each CORESET / resource / resource set, and the configured TCI state may not be updated even if the indicated TCI state is updated. It is considered that the indicated TCI state is applied to the UE-specific channel / signal (RS). It is also considered that the UE is notified of whether the indicated TCI state or the configured TCI state is applied to the non-UE-specific channel / signal by using higher layer signaling (RRC signaling). It is being considered that the RRC parameters for the configured TCI state (TCI state ID) will have the same configuration as the RRC parameters for the TCI state in Rel. 15 / 16. It is being considered that the configured TCI state will be configured / instructed for each CORESET / for each resource / for each resource set using RRC / MAC CE. It is also being considered that the UE will make a decision regarding the configuration / instruction based on a specific parameter. It is considered that the UE updates the indicated TCI state and the configured TCI state separately. For example, when 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 the update based on a specific parameter. In addition, regarding the PDCCH / PDSCH, a study is being conducted on switching, using higher layer signaling (RRC / MAC CE), between whether the indicated TCI state is applied or not applied (the configured TCI state is applied, or a TCI state configured separately from the indicated TCI state is applied). In addition, with regard to intra-cell beam indication (TCI state indication), it is being considered that indication TCI state will be supported for a UE-specific CORESET and a PDSCH associated with the CORESET, and a non-UE-specific CORESET and a PDSCH associated with the CORESET. In addition, for inter-cell beam indication (e.g., L1 / L2 inter-cell mobility), it is being considered that indication TCI state will be supported for a UE-specific CORESET and the PDSCH associated with the CORESET. In Rel. 15, whether to indicate the TCI state for CORESET #0 was up to the base station implementation. In Rel. 15, for CORESET #0 for which the TCI state is indicated, the indicated TCI state is applied. For CORESET #0 for which the TCI state is not indicated, the SSB and QCL selected at the time of the latest (most recent) PRACH transmission are applied. In the unified TCI state framework for Rel. 17 and later, the TCI state for CORESET #0 is being considered. 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 TCI state indication of CORESET#0 (Rel. 17) is set by RRC for each CORESET, and if not applied, the legacy MAC CE / RACH signalling mechanism may be used. In addition, in Rel. 17, the CSI-RS related to the TCI state applied to CORESET #0 may be QCL'd with the SSB related to the serving cell PCI (physical cell ID) (similar to Rel. 15). For CORESET#0, CORESET with common search space (CSS), and CORESET with CSS and UE-specific search space (USS), whether to follow the indicated TCI state may be configured for each CORESET by an RRC parameter. If the indicated TCI state is not configured for the CORESET, the configured TCI state may be applied to the CORESET. For non-UE-dedicated channels / RSs (except CORESET), an RRC parameter may be configured for each channel / resource / resource set as to whether to follow the indicated TCI state. If the indicated TCI state is not configured for that channel / resource / resource set, the configured TCI state may be applied for that channel / resource / resource set. [Antenna Port QCL...Physical Layer Procedures for Data] The UE can configure a list of up to M TCI-States in the higher layer parameter PDSCH-Config for decoding of PDSCH according to the detected PDCCH with DCI for the UE and a given serving cell, where M depends on the UE capability maxNumberConfiguredTCIstatesPerCC. Each TCI-State includes parameters for configuration of QCL relationship between one or two downlink reference signals and the DM-RS port of PDSCH or the DM-RS port of PDCCH or the CSI-RS port of CSI-RS resources. The QCL relationship 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). In the case of two DL RSs, the QCL types are not the same, regardless of whether the references are the same DL RS or different DL RSs. The QCL type corresponding to each DL RS is given by the higher layer parameter qcl-Type in QCL-Info and may take 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 parameters} In order to provide reference signals for PDSCH DMRS and PDCCH DMRS, CSI-RS in a CC, and further to provide a reference for UL TX (transmission) spatial filter determination for dynamic and configuration grant based PUSCH and PUCCH resources, SRS in a CC, if such filters are available, the UE can configure a list of up to 128 DLorJointTCIState configurations in PDSCH-Config. If there is no configuration of a TCI state (DL or joint TCI state (TCI-State) or UL TCI state (TCI-UL-State)) in the BWP in that CC, the UE may apply the configuration of the TCI-State or TCI-UL-State from the reference BWP of the reference CC. If the UE has configured dl-OrJointTCI-StateList or TCI-UL-State in any CC in the same band, it does not expect the tci-StatesToAddModList (TCI state list for adding modifications), SpatialRelationInfo (spatial relation information), PUCCH-SpatialRelationInfo (PUCCH spatial relation information) except SpatialRelationInfoPos (spatial relation information for position) in that band to be configured. The UE may assume that if the UE has TCI-State in any CC in the CC list configured by simultaneousTCI-UpdateList1-r16, simultaneousTCI-UpdateList2-r16, simultaneousSpatial-UpdatedList1-r16, or simultaneousSpatial-UpdatedList2-r16, the UE does not have dl-OrJointTCI-StateList or TCI-UL-State configured in any CC in the same band in the CC list. The UE receives an activation command used to map up to eight TCI states and / or up to eight TCI state pairs, with one TCI state for DL ​​channels / signals and / or one TCI state for UL channels / signals, to codepoints of the DCI field 'Transmission Configuration Indication' for one or a set of CCs / DL BWPs and, if applicable, one or a set of CCs / UL BWPs, as described in the TCI States Activation / Deactivation for UE-specific PDSCH MAC CE or Unified TCI States Activation / Deactivation MAC CE in the MAC protocol specification. For a set of CCs / DL BWPs and, if applicable, a set of CCs / UL BWPs, a set of TCI State IDs is activated and when the applicable list of CCs is determined by the CCs indicated in the activation command, the same set of TCI State IDs applies to all DL and / or UL BWPs within the indicated CC. If the activation command maps the TCI state (TCI-State and / or TCI-UL-State) to only one code point, and the indicated mapping for that single TCI code point is applied as described in the requirements for Radio Resource Management (RRM) support (MAC CE based DL TCI state switching delay / MAC CE based UL TCI state switching delay), the UE applies the indicated TCI state (TCI-State and / or TCI-UL-State) to one or a set of CCs / DL BWPs and, if applicable, to one or a set of CCs / UL BWPs. If the bwp-id or cell for a QCL type A / D source RS in the QCL-Info of a TCI state is not configured, the UE shall assume that the QCL type A / D source RS is configured in the CC / DL BWP to which the TCI state applies. If the TCI field is configured to be present in the DCI for CORESET (tci-PresentInDCI set to 'enabled' or tci-PresentDCI-1-2 is configured), a UE configured with a DL or joint TCI state list (dl-OrJointTCI-StateList) with an activated TCI state (TCI-State or TCI-UL-State) receives DCI format 1_1 / 1_2 providing an indication TCI state (at least one of TCI-State and TCI-UL-State) for one CC or for all CCs in the same CC list configured by the simultaneous unified TCI update list (simultaneousU-TCI-UpdateList1-r17, simultaneousU-TCI-UpdateList2-r17, simultaneousU-TCI-UpdateList3-r17, simultaneousU-TCI-UpdateList4-r17). The DCI format 1_1 / 1_2 may be accompanied by a DL assignment if one is available, or may be without a DL assignment. If DCI format 1_1 / 1_2 does not carry a DL assignment, the UE can assume (verify): - The CS-RNTI is used to scramble the CRC for that 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). If the UE receives a higher layer configuration of dl-OrJointTCI-StateList with a single TCI-State that can be used as the indication TCI state, the UE derives QCL assumptions from the configured TCI states for the PDSCH DM-RS, PDCCH DM-RS and CSI-RS for which that indication TCI state applies. If the UE receives higher layer configuration of dl-OrJointTCI-StateList with a single TCI-State or a single TCI-UL-State that can be used as the indicated TCI state, the UE shall determine the UL TX spatial filter from the configured TCI state, if applicable, for dynamic and configured grant based PUSCH, PUCCH and SRS that apply to the indicated TCI state. When a UE that has been configured with a list of DL or joint TCI states (dl-OrJointTCI-StateList) attempts to transmit a PUCCH with a positive HARQ-ACK or a PUSCH with a positive HARQ-ACK that corresponds to a DCI that transmits a TCI state indication and does not have a DL assignment, or that corresponds to a PDSCH scheduled by a DCI that transmits a TCI state indication, and if the indicated TCI state is different from a previously indicated indicated TCI state, the indicated TCI state (at least one of the indicated TCI-State and the indicated TCI-UL-State) starts to be applied from the first slot (beam application timing 1) that is at least beamAppTime symbols (beam application time (BAT)) after the last symbol of that PUCCH or that PUSCH. Both the first slot and the beamAppTime symbols are determined on the active BWP with the minimum SCS among the BWPs from the CC that applies the indicated TCI state (at least one of the indicated TCI-State and the indicated TCI-UL-State) that is active at the end of the PUCCH or the PUSCH transmitting the positive HARQ-ACK. [DCI Format 1_1...Multiplexing and Channel Coding] In Rel. 15 / 16, if the UE does not support active BWP change via DCI, the UE ignores the BWP indicator field. A similar behavior is considered for the relationship between the support of Rel. 17 TCI state and the interpretation of the TCI field. It is considered that if the UE is configured with Rel. 17 TCI state, the TCI field is always present in DCI format 1_1 / 1_2, and if the UE does not support TCI update via DCI, the UE ignores the TCI field. In Rel. 15 / 16, whether or not a TCI field is present (TCI presence information in DCI, tci-PresentInDCI) is set for each CORESET. The TCI field in DCI format 1_1 is 0 bits if the higher layer parameter tci-PresentInDCI is not enabled, otherwise it is 3 bits. 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 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. 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. A TCI status ID indicating the joint DL / UL TCI status is associated with the value of the TCI field for indicating the joint DL / UL TCI status. At least one TCI state ID is associated with a value of the TCI field for indicating a separate DL / UL TCI state, that is, a TCI state ID indicating a TCI state of only DL and a TCI state ID indicating a TCI state of only UL. For example, the values ​​000 to 001 in the TCI field are associated with only one TCI state ID for DL, the values ​​010 to 011 in the TCI field are associated with only one TCI state ID for UL, and the values ​​100 to 111 in the TCI field are associated with both one TCI state ID for DL ​​and one TCI state ID for UL. [Channel / RS to which the indicated TCI status applies] The indicated TCI state by the MAC CE / DCI may apply to the following channels / RS: [PDCCH] If followUnifiedTCIState is set for CORESET0, the indicated TCI state is applied. Otherwise, the Rel. 15 specifications are applied for that CORESET. That is, CORESET0 follows the TCI state activated by the MAC CE or is QCL'd with SSB. For a CORESET with index other than 0 with USS / CSS type 3, the indicated TCI state always applies. For a CORESET with index other than 0, with at least a CSS other than CSS type 3, configured to follow the uniform TCI state, the indicated TCI state applies. Otherwise, the configured TCI state for that CORESET applies to that CORESET. [PDSCH] - The indicated TCI state always applies for all UE-dedicated PDSCHs. For a non-UE-dedicated PDSCH (PDSCH scheduled by a DCI in the CSS), if followUnifiedTCIState is set (for the CORESET of the PDCCH that schedules the PDSCH), the indicated TCI state may apply. Otherwise, the configured TCI state for the PDSCH applies to the 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 the PDSCH. [CSI-RS] For an A-CSI-RS for CSI acquisition or beam management, if followUnifiedTCIState is set (for the 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. [PUCCH] - For all dedicated PUCCH resources, the indicated TCI state always applies. [PUSH] For dynamic / configured grant PUSCH, the indicated TCI state is always applied. [SRS] If the SRS resource set for the A-SRS for beam management and the A / SP / P-SRS for codebook (CB) / non-codebook (NCB) / antenna switching is configured to follow the unified TCI state, the indicated TCI state is applied. For other SRS, the configured TCI state in the SRS resource set is applied. In the present disclosure, the indicated TCI state, the unified TCI state, the TCI state applied to channels / signals that are configured to follow the unified TCI state, the TCI state applied to the UE-individual PDSCH and the CORESET / PDCCH associated with the USS, and the TCI state applied to the PUCCH and the PUSCH may be read as interchangeable. (CSI report or reporting) In Rel. 15 NR, a terminal (also referred to as a user terminal, User Equipment (UE), etc.) generates (also referred to as determining, calculating, estimating, measuring, etc.) channel state information (CSI) based on a reference signal (RS) (or a resource for the RS), and transmits (also referred to as reporting, feedback, etc.) the generated CSI to a network (e.g., a base station). The CSI may be transmitted to the base station, for example, using an uplink control channel (e.g., a Physical Uplink Control Channel (PUCCH)) or an uplink shared channel (e.g., a Physical Uplink Shared Channel (PUSCH)). The RS used to generate the CSI may be, for example, at least one of a Channel State Information Reference Signal (CSI-RS), a Synchronization Signal / Physical Broadcast Channel (SS / PBCH) block, a Synchronization Signal (SS), a DeModulation Reference Signal (DMRS), etc. The CSI-RS may include at least one of a Non Zero Power (NZP) CSI-RS and a CSI-Interference Management (CSI-Interference Measurement, CSI-IM). The SS / PBCH block is a block including an SS and a PBCH (and a corresponding DMRS), and may be referred to as an SS block (SSB), etc. The SS may include at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). In addition, the CSI may include at least one of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), a SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), L1-RSRP (Layer 1 Reference Signal Received Power), L1-RSRQ (Reference Signal Received Quality), L1-SINR (Signal to Interference plus Noise Ratio), and L1-SNR (Signal to Noise Ratio). The UE may receive information on CSI reporting (report configuration information) and control CSI reporting based on the report configuration information. The report configuration information may be, for example, "CSI-ReportConfig" of an information element (IE) of Radio Resource Control (RRC). In the present disclosure, the RRC IE may be interchangeably read as an RRC parameter, a higher layer parameter, or the like. The reporting configuration information (e.g., the RRC IE "CSI-ReportConfig") may include, for example, at least one of the following: Information regarding the type of CSI report (report type information, e.g., RRC IE "reportConfigType") Information on one or more quantities of CSI to be reported (one or more CSI parameters) (report quantity information, e.g., RRC IE “reportQuantity”) Information on the RS resource used to generate the amount (the CSI parameter) (resource information, for example, “CSI-ResourceConfigId” of the RRC IE) Information on the frequency domain to which the CSI is reported (frequency domain information, for example, the RRC IE "reportFreqConfiguration") For example, the report type information may indicate a periodic CSI (Periodic CSI (P-CSI)) report, an aperiodic CSI (A / AP-CSI) report, or a semi-persistent CSI (Semi-Persistent CSI (SP-CSI)) report. Furthermore, the reporting amount information may specify at least one combination of the above CSI parameters (e.g., CRI, RI, PMI, CQI, LI, L1-RSRP, etc.). The resource information may also be an ID of a resource for the RS. The resource for the RS may include, for example, a non-zero power CSI-RS resource or an SSB, and a CSI-IM resource (for example, a zero power CSI-RS resource). The frequency domain information may also indicate frequency granularity of the CSI report. The frequency granularity may include, for example, a wideband and a subband. The wideband is the entire CSI reporting band. The wideband may be, for example, the entirety of a certain carrier (Component Carrier (CC)), cell, serving cell), or the entirety of a bandwidth part (BWP) in a certain carrier. The wideband may be rephrased as a CSI reporting band, the entire CSI reporting band, etc. Also, a subband is a part of a wideband and may be composed of one or more resource blocks (RBs or PRBs). The size of the subband may be determined according to the size of the BWP (the number of PRBs). The frequency domain information may indicate whether wideband or subband PMI is to be reported (the frequency domain information may include, for example, an RRC IE "pmi-FormatIndicator" used to determine whether wideband PMI reporting or subband PMI reporting is to be performed). The UE may determine the frequency granularity of the CSI report (i.e., whether wideband PMI reporting or subband PMI reporting) based on at least one of the above-mentioned report amount information and frequency domain information. If wideband PMI reporting is configured, one wideband PMI may be reported for the entire CSI reporting band, whereas if subband PMI reporting is configured, a single wideband indication i1 may be reported for the entire CSI reporting band, and one subband indication i2 (e.g., a subband indication for each subband) may be reported for each of the one or more subbands within the entire CSI reporting band. The UE performs channel estimation using the received RS to estimate a channel matrix H. The UE feeds back a PMI determined based on the estimated channel matrix. The PMI may indicate a precoder matrix (also referred to as a precoder) that the UE considers appropriate to use for downlink (DL) transmission to the UE. Each value of the PMI may correspond to one precoder matrix. A set of values ​​of the PMI may correspond to a set of different precoder matrices, called a precoder codebook (also referred to as a codebook). In the space domain, the CSI report may include one or more types of CSI. For example, the CSI may include at least one of a first type (type 1 CSI) used for selecting a single beam and a second type (type 2 CSI) used for selecting a multi-beam. The single beam may be rephrased as a single layer, and the multi-beam may be rephrased as multiple beams. In addition, the type 1 CSI does not assume multi-user multiple input multiple output (MU-MIMO), and the type 2 CSI may assume multi-user MIMO. The codebook may include a codebook for type-1 CSI (also referred to as a type-1 codebook, etc.) and a codebook for type-2 CSI (also referred to as a type-2 codebook, etc.). Furthermore, the type-1 CSI may include type-1 single-panel CSI and type-1 multi-panel CSI, and different codebooks (type-1 single-panel codebook, type-1 multi-panel codebook) may be defined for each. In the present disclosure, Type 1 and Type I may be interpreted as interchangeable. In the present disclosure, Type 2 and Type II may be interpreted as interchangeable. The uplink control information (UCI) type may include at least one of a hybrid automatic repeat reQuest ACKnowledgement (HARQ-ACK), a scheduling request (SR), and CSI. The UCI may be carried by the PUCCH or the PUSCH. In Rel. 15 NR, UCI may contain one CSI part for wideband PMI feedback. CSI report #n contains PMI wideband information if reported. In Rel. 15 NR, UCI can include two CSI parts for subband PMI feedback. CSI part 1 includes wideband PMI information. CSI part 2 includes one wideband PMI information and some subband PMI information. CSI part 1 and CSI part 2 are coded separately. In Rel. 15 NR, the UE is configured by a higher layer with N (N≧1) CSI reporting configuration report settings and M (M≧1) CSI resource configuration resource settings. For example, the CSI reporting configuration (CSI-ReportConfig) includes channel measurement resource settings (resourcesForChannelMeasurement), interference CSI-IM resource settings (csi-IM-ResourceForInterference), interference NZP-CSI-RS settings (nzp-CSI-RS-ResourceForInterference), and report quantity (reportQuantity). Each of the channel measurement resource settings, interference CSI-IM resource settings, and interference NZP-CSI-RS settings is associated with a CSI resource configuration (CSI-ResourceConfig, CSI-ResourceConfigId). The CSI resource configuration includes a list of CSI-RS resource sets (csi-RS-ResourceSetList, for example, an NZP-CSI-RS resource set or a CSI-IM resource set). (JT) A joint transmission (JT) may refer to simultaneous data transmission from multiple points (eg, TRPs) to a single UE. Rel. 17 supports non-coherent joint transmission (NCJT) from two TRPs. The PDSCHs from the two TRPs may be precoded and decoded independently. The frequency resources may be non-overlapping, partially overlapping, or fully overlapping. When overlapping occurs, the PDSCH from one TRP will interfere with the PDSCH from the other TRP. In Rel. 18, support for coherent joint transmission (CJT, mTRP CJT) with up to four TRPs is being considered. Data from the four TRPs may be coherently precoded and transmitted to the UE on the same time-frequency resource. For example, the same precoding matrix may be used to consider channels from the four TRPs. "Coherent" may mean that there is a certain relationship between the phases of multiple received signals. With 4TRP joint precoding, signal quality may be improved and there may be no interference between the four TRPs. Data may only experience interference outside the four TRPs. (CJT CSI / Type 2 Codebook) In the ideal case (where the four TRPs are collocated), a joint estimation of the aggregated channel matrix H can be performed and a joint precoding matrix V can be fed back. However, the large scale path losses of the four paths may vary significantly. The joint precoding matrix V based on a constant module codebook is not accurate. In this case, the feedback per TRP and the inter-TRP coefficients can be matched with the current NR type 2 codebook. For a CJT of up to four TRPs in FR1, the selection of the four TRPs may be semi-static, and thus the selection and configuration of the four channel measurement resources (CMRs, four CSI-RS resources for channel measurement) may also be semi-static. Dynamic indication of the four TRPs from a list of CSI-RS resources is also possible, but unlikely. The path losses from the four TRPs to the UE are different, so it is difficult to simply report one aggregated CSI that represents the joint channel matrix. Considering fallback operation to NCJT (i.e., single-TRP), per-TRP CSI (i.e., single-TRP CSI like NCJT CSI in Rel. 17) is also considered. Assuming ideal backhaul, synchronization, and the same number of antenna ports across multiple TRPs, CSI acquisition for coherent joint transmission (CJT) for FR1 and up to four TRPs is considered. For CJT multi-TRP for FDD, an extended (Rel. 16) type-2 codebook and an additional extended (Rel. 17) type-2 PS codebook improvement are considered. W1 (matrix representing SD DFT vector) / W for each TRP f (Matrix representing FD DFT vector) may be the same or different. l (NZC) may be different. W1 / W for each TRP f / W l may be selected jointly or individually. W1 / W f / W l Different scenarios with different options for the design of W are preferable. φ may be reported as separate items or l These used policies relate to deployment scenarios (e.g., intra-site multi-TRP or inter-site multi-TRP). For example, the precoding matrix for a 4-TRP CJT CSI (codebook) is W1 / W f / W l W1 for each TRP may be the same or different, and may be selected jointly or individually. W1 for each TRP may be the same or different, and may be selected jointly or individually. l may be different and may be selected jointly or individually. fmay be the same or different and may be selected jointly or individually. There are two codebook mode settings for FD basis selection. In mode 1, let i denote the FD basis offset for the j-th selected CSI-RS resource for j=2,...,N. 1,9 Reporting is required. In mode 2, i 1,9 No reporting is required. All CSI-RS resources have the same FD basis selection. - Mode 1 is SD / FD basis selection per TRP / TRP group, which allows independent FD basis selection across N TRPs / TRP groups, where N is the number of TRPs or TRP groups. Mode 2 is SD basis selection per TRP / TRP group (port group or resource) and joint / common FD basis selection (across N TRPs / TRP groups), where N is the number of TRPs or TRP groups. In the present disclosure, the CSI-RS resource, the CSI-RS resource set, the NZP CSI-RS resource, the CMR, the CMR for CJT, and the CSI-RS resource for channel measurement may be read as interchangeable. In this disclosure, TRP and TRP group may be read as interchangeable. In these two modes, detailed designs such as parameter combination, basis selection, TRP (group) selection, reference amplitude, and W2 quantization scheme may be shared. For the enhanced Type II codebook for CJT (type 2 CSI for CJT in Rel. 18), the UE may configure the higher layer parameter codebookType set to 'typeII-CJT-r18'. For the further enhanced Type II port selection codebook for CJT (type 2 PS CSI for CJT in Rel. 18), the UE may configure the higher layer parameter codebookType set to 'typeII-CJT-PortSelection-r18'. The UE selects N TRP ∈{1,2,3,4} CSI-RS resources can be configured. In the extended type 2 codebook for CJT, the upper layer parameter paramCombination-CJT-L-r18 determines the combination of {L1,...,L N_TRP} value of N L A set of ∈{1,2,4} combinations is set. N L The value of is set by the higher layer parameter numberOfSDCombinations. In the CJT additional extension type 2 PS codebook, the upper layer parameter paramCombination-CJT-PS-alpha-r18 determines {α1,...,α N_TRP} value of N L A set of ∈{1,2,4} combinations is set. N L The value of is set by the higher layer parameter numberOfSDCombinations-PS. The UE may configure the higher layer parameter restrictedCMR-Selection. If restrictedCMR-Selection is configured, the number of selected CSI-RS resources N is N TRP Otherwise, the UE TRPFor each CSI-RS resource, we expect to select N CSI-RS resources. TRP The bitmap is reported using 16 bits. In selecting / reporting an SD beam, selection / reporting of an SD beam per CSI-RS resource is applied. In the extended type 2 codebook for CJT, the precoding matrix indicated by the PMI is Σ j=1 N L σ_j +M v vectors, where {σ1,...,σ N} is 1≦σ1<…<σ N ≦N TRP are the indices of the N CSI-RS resources selected in ascending order such that TRP may be the number of CSI-RS resources configured for CSI reporting, or the number of TRPs for CJT. σ_1 ,...,L σ_N} is {L1,...,L N_TRP} is the corresponding value from a selected combination. j=1,...,N, i=0,1,...,L σ_j −1, L corresponding to the j-th selected CSI-RS resource σ_j Vector v m_1,f^(i),m_2,f^(i) i 1,1 , i 1,2 It is displayed / reported by, where i 1,1 , i 1,2 is given by the following equation: i 1,1 =[i 1,1,1 ... i 1,1,N ] i 1,1,j =[q 1,j q 2,j ] q 1,j ∈{0,1,...,O1-1} q 2,j ∈{0,1,...,O2-1} i 1,2 =[i 1,2,1 ... i 1,2,N ] i1,2,j ∈{0,1,...,C(N1N2,L σ_j )-1} In the additional extended type 2PS codebook for CJT, the precoding matrix indicated by the PMI is Σ j=1 N L σ_j +M vectors, where {σ1,...,σ N} is 1≦σ1<…<σ N ≦N TRP L is the index of the N CSI-RS resources selected in ascending order such that σ_j =K 1,σ_j / 2, K 1,σ_j = α σ_j *P CSI-RS {α σ_1 ,...,α σ_N} is {α1,...,α N_TRP} is the corresponding value from a selected combination. j=1,...,N, i=0,1,...,L σ_j -1, L σ_j Vector v m_j^(i) Based on the j-th selected CSI-RS resource P CSI-RS From the ports, K 1,σ_j ports are selected and i 1,2 It is displayed / reported by, where i 1,2 is given by the following equation: i 1,2 =[i 1,2,1 ... i 1,2,N ] i 1,2,j ∈{0,1,...,C(P CSI-RS ,L σ_j )-1} In the present disclosure, the codebook for CJT, the type 2 codebook for CJT, the extended type 2 codebook for CJT, the type 2 codebook for Rel. 18 CJT, typeII-CJT-r18, the additional extended type 2 PS codebook for CJT, the type 2 PS codebook for Rel. 18 CJT, and typeII-CJT-PortSelection-r18' may be read as interchangeable. Study #0: Unified TCI Conditions for A-CSI-RS It is contemplated that the indicated joint / DL TCI state may be applied only to the A-CSI-RS for CSI / beam management (BM), and not to the P / SP-CSI-RS, for which the joint / DL TCI state is configured per CSI-RS resource or CSI-RS resource set. [mDCI mTRP] An extension of the unified TCI framework for multi-DCI (M-DCI, mDCI) based multi-TRP (MTRP, mTRP) is being considered. In the case where an A-CSI-RS resource set for CSI / BM is configured to follow Unified TCI state, an RRC configuration can be provided for the A-CSI-RS resource set or for the CSI-RS resources within the A-CSI-RS resource set to inform the UE to apply the first or second indicated joint / DL TCI state to the A-CSI-RS resource set or for the CSI-RS resources within the A-CSI-RS resource set. - The TCI state of the first or second indicated joint / DL corresponds to the TCI state of the indicated joint / DL specific to coresetPoolIndex values ​​0 and 1 respectively. - The above configuration method applies at least if the offset between the last symbol of the PDCCH carrying the triggering DCI and the starting symbol of the A-CSI-RS resource in that A-CSI-RS resource set is greater than or equal to a threshold (if that threshold is required). - It is up to the UE capability to support RRC configuration per CSI-RS resource set or per CSI-RS resource. For A-CSI-RS, the RRC parameters {1st, 2nd} indicate the association between the indicated TCI state and the CSI-RS resource set. For UEs that do not support the two default buffering capabilities, the case where the offset is smaller than a threshold is described below. [sDCI mTRP] An extension of the unified TCI framework for single DCI (S-DCI, sDCI) based MTRP is being considered. In the case where the A-CSI-RS resource set for CSI / BM is configured to follow Unified TCI state, an RRC configuration can be provided in the CSI-AssociatedReportConfigInfo of CSI-AperiodicTriggerState for each CSI-RS resource set or for each A-CSI-RS resource in each A-CSI-RS resource set to indicate that the UE applies the first or second indicated joint / DL TCI state to that CSI-RS resource. - The above configuration method applies at least if the offset between the last symbol of the PDCCH carrying the triggering DCI and the starting symbol of the A-CSI-RS resource in that A-CSI-RS resource set is greater than or equal to a threshold (if that threshold is required). - It is up to the UE capability to support RRC configuration per CSI-RS resource set or per CSI-RS resource. Different DCI code points in the CSI request field indicate the {1st, 2nd} indicated TCI states for the A-CSI-RS. The default TCI state for the A-CSI-RS (when the triggering offset is less than a threshold) is described below. Whether the association of {first, second} is per CSI-RS resource or per CSI-RS resource set can be configured by the NW. (Study #1: Unified TCI Conditions for CJT) [Study #1-1] Regarding the extension of the unified TCI framework, it is considered that PDSCH-CJT is supported as an S-DCI based MTRP method. This does not preclude the considerations inherent in the PDSCH-CJT design within the unified TCI framework. In other words, CJT reuses / repurposes the specifications of the S-DCI MTRP. [Study #1-2] Regarding the extension of the unified TCI framework, it is considered that two joint TCI states can be indicated by MAC CE / DCI and can be applied to CJT-based PDSCH reception (PDSCH-CJT) in BWP / CC with joint DL / UL TCI mode. It is up to the UE capability to support one indicated joint TCI state for PDSCH-CJT or two indicated joint TCI states. It is considered how to inform the UE which indicated joint TCI state should be applied to the target channel / signal in that BWP / CC. That is, the number of TCI states for CJT is 1 or 2. [Study #1-3] With regard to the extension of the unified TCI framework for S-DCI based MTRP, it is considered that the following two options are supported for PDSCH-CJT applying both indicated joint TCI states (if the UE supports two indicated joint / DL TCI states for PDSCH-CJT): - Option 1: The PDSCH DMRS port is QCL'd with respect to DL RS in both indicated joint TCI states and QCL type A. - Option 2: The PDSCH DMRS port is QCL'd with respect to DL RS in both indicating joint TCI states and QCL type A except for the QCL parameters {Doppler shift, Doppler spread} in the second indicating joint TCI state. A UE capability regarding which option is supported is introduced, and either of the above two options can be configured by the RRC according to the UE capability. In PDSCH-CJT, QCL is supported for both SFN scheme A and SFN scheme B. Additional QCL rules (one is QCL type A and the other is QCL type B) are not supported. (Study #2: CJT CMR) [Study #2-1] N TRP > N with equal priority in Rel. 18 Type 2 codebook refinement for CJT multi-TRP (mTRP) with 1 TRP / TRP group TRP = {1,2,3,4} is being considered for support. In other words, the number of TRPs / TRP groups is up to 4. [Study #2-2] N TRP In the Rel. 18 Type 2 codebook refinement for CJT mTRPs with >1 TRP / TRP group, the following are considered to be supported: - The CMR comprises K>1 NZP CSI-RS resources, where one resource corresponds to one TRP / TRP group, i.e., K=N TRP Each of the multiple CSI-RS resources has the same number of CSI-RS ports. One CMR is supported per TRP / TRP group. [Study #2-3] In the type-2 codebook refinement for CJT mTRP, it is considered that the selection of N CSI-RS resources is done by the UE and reported as part of the CSI report, where N ∈ {1,...,N TRP}, where N is the number of collaborative CSI-RS resources. TRP is the maximum number of cooperative CSI-RS resources configured by the base station via higher layer signaling. TRP The selection of N CSI-RS resources among the N CSI-RS resources is TRPThat is, the UE reports the TRP selection by a bitmap indication, e.g., if four TRPs are configured, the UE can select the first and third TRPs for CJT CSI reporting, and a bitmap indicating that the first and third TRPs are selected is

[1010] N is inferred from the selection, which may be set by the base station or selected by the UE, L n N TRP Candidate values ​​for are 1, 2, 3, 4. Only one transmit hypothesis is reported. The UE is not required to calculate CSI for multiple transmit hypotheses. That is, both TRP configuration by the base station (TRP is not selected by the UE) and TRP selection by the UE are supported. TRP selection by the UE is an optional feature of the UE. Consideration #1 defines the UE's QCL assumption for the PDSCH DMRS port in decoding the PDSCH when the number of indicated TCI states is 1 or 2. However, the number of N set TCI states / indicated TCI states for the PDSCH-CJT is 1 or 2. TRP It is not clear that (four or less) CMRs need to be mapped. Up to two indication TCI states are applied to the DMRS of the PDSCH, up to four CMRs can be set, and it is considered that the DMRS of the PDSCH for CJT is QCLed with the CMR for CJT. However, the constraints on the QCL of the CMR for CJT have not been fully considered. It is also considered that the DMRS of the PDSCH for CJT is not required to be QCLed with the CMR for CJT. In this case, the constraints can be relaxed. In this way, the QCL assumption of the CMR in the CJT or the unified TCI state (or the indicated TCI state) for the CJT has not been sufficiently considered. If the QCL assumption of the CMR in the CJT or the unified TCI state (or the indicated TCI state) for the CJT is not sufficiently considered, there is a risk of causing a decrease in communication quality / throughput. Therefore, the inventors have studied a method for determining the QCL assumption of the CMR in the CJT, or the application of the unified TCI state (or the instruction TCI state) to the CJT, and have come up with an aspect of the present embodiment.

(Wireless communication method) <Embodiment A0> Regarding the constraint between the CMR and the TCI state / RS, two cases are considered: - Case 1: If the RRC IE configures at least one of the CMR and the TCI state, then a constraint (between the CMR and the configured / activated TCI state (pair)) is considered, or if no TCI state is configured for a CMR, the UE assumes the QCL of that CMR (UE assumes / determines QCL). - Case 2: Restrictions are considered where one or two indicated TCI states apply (and where the indicated TCI states apply to P / SP / A-CSI-RS resources for channel measurements). <Embodiment A1> This embodiment mainly relates to case 1. The number of CSI-RS resources (CMRs) configured for channel measurement and the TCI state for CJT may follow at least one of the following options: - Option 0 N to be set TRPThere may be no constraint / assumption for mapping (four or less) CMRs to the indication (configured / activated) TCI states for PDSCH-CJT. In this case, up to four CMRs (CSI-RS resources for channel measurement, e.g., CMRs #1, #2, #3, #4) may be configured to be associated with up to four different TCI states (e.g., TCI states #a, #b, #c, #d) respectively (up to four different TCI states may be configured for up to four CMRs respectively). At least one of the four TCI states may be an indication TCI state (for CJT), or there may be a constraint that at least two of the four TCI states are indication TCI states (for CJT). In the Option 0 example of FIG. 1A, CMRs #1, #2, #3, and #4 are associated with TCI states #a, #b, #c, and #d, respectively. - Option 1 There may be a constraint that all CSI-RS resources (CMRs, e.g., CMRs #1, #2, #3, #4) configured for channel measurement share one and the same TCI state (e.g., TCI state #a). There may be a constraint that all CSI-RS resources configured for channel measurement are associated with one and the same SSB / CSI-RS, which is the QCL source RS of one TCI state. The constraint of this option may be realized by at least one of the following: an assumption by the UE, a configuration by the RRC, and a definition in the specification. For example, the UE may assume / determine that the antenna ports of all CSI-RS resources configured for channel measurement are QCLed with the same one SSB / CSI-RS that is a QCL source RS of one TCI state. For example, the same one SSB / CSI-RS that is a QCL source RS of one TCI state may be configured for all CSI-RS resources configured for channel measurement. In this option, the one TCI state (e.g., TCI state #a) may be one indicated TCI state (for CJT). In the example of option 1 of FIG. 1B, CMRs #1, #2, #3, and #4 are all associated with the same TCI state #a. - Option 2 There may be a constraint that all CSI-RS resources (CMRs, e.g., CMRs #1, #2, #3, #4) configured for channel measurement share the same one or two TCI states (e.g., TCI states #a, #b). There may be a constraint that all CSI-RS resources configured for channel measurement are associated with the same one or two SSB / CSI-RSs that are QCL source RSs for the one or two TCI states. If all the CSI-RS resources are associated with two TCI states, this option may follow at least one of several options 2-x below. -- Option 2-1: Every CMR is associated / QCLed with two DL RSs in the TCI state for QCL type A. -- Option 2-2: All CMRs are associated / QCL'd with two DL RSs in TCI states for QCL type A except for {Doppler shift, Doppler spread} in the second indicated TCI state. The constraint of this option may be realized by at least one of the following: assumption by the UE, configuration by the RRC, and definition in the specification. For example, the UE may assume / determine that the antenna ports of all CSI-RS resources configured for channel measurement are QCLed with the same one or two SSB / CSI-RSs that are QCL source RSs of one or two TCI states. For example, the same one or two SSB / CSI-RSs that are QCL source RSs of one or two TCI states may be configured for all CSI-RS resources configured for channel measurement. In this option, the one or two TCI states (e.g., TCI state #a / #b) may be one or two indicated TCI states (for CJT). In the example of Option 2 of FIG. 1C, CMRs #1, #2, #3, and #4 are all associated with the same two TCI states #a, #b. - Option 3 Some CSI-RS resources (CMRs, e.g., CMRs #1, #2, #3, #4) configured for channel measurement may be associated with a first indicated (activated) TCI state from a pair of TCI states for CJT, and the remaining CSI-RS resources configured for channel measurement may be associated with a second indicated (activated) TCI state from a pair of TCI states for CJT. The association between the CMRs and the TCI states may be determined by at least one of the following options 3-x. -- Option 3-1: RRC signaling. For example, the RRC IE may set an association between the CSI-RS resource and the TCI state. It may be possible for more than one CSI-RS resource to be associated with the same TCI state. For example, the RRC IE may set an association between the CSI-RS resource and another RS ​​(e.g., SSB / CSI-RS), which may be the QCL source RS of the TCI state. -- Option 3-2: Assumption by rule or UE. For example, the first X CSI-RS resources may be associated with the first indicated (activated) TCI state for CJT, and the remaining CSI-RS resources may be associated with the second indicated (activated) TCI state for CJT. X may be 1 or ceil(N TRP / 2) or floor(N TRP For example, the UE may assume / determine according to the rule that the antenna ports of the first X CSI-RS resources are QCL'd with the RS in the first indicated (activated) TCI state for CJT, and the antenna ports of the remaining CSI-RS resources are QCL'd with the RS in the second indicated (activated) TCI state for CJT. In this option, TCI state #a / #b may be one or two indicating TCI states (for CJT). In the example of option 3 of FIG. 1D, CMRs #1 and #2 are associated with one TCI state #a, and CMRs #3 and #4 are associated with another TCI state #b. The same option among the above several options may be applied to the P / SP / A-CSI-RS for channel measurement, or a different option among the above several options may be applied. - Variations Variations based on options 1 / 2 / 3 are possible. TRP There may be a constraint that at least one CMR out of four CMRs (e.g., at least two CMRs in option 3) is associated with one indicated TCI state (e.g., TCI state #a). There may be a constraint that at least one CMR out of four CMRs (e.g., at least two CMRs in option 3) is associated with two indicated TCI states (e.g., TCI states #a, #b). There may be no constraint for the remaining CMRs. In an example variation of Option 1 in Fig. 2A, CMRs #3 and #4 in the above example of Option 1 (Fig. 1B) are associated with different TCI states #e and #f, respectively. At least one of TCI states #a, #e, and #f may be an indication TCI state, which may be the same as in Option 0. In an example variation of Option 2 in Fig. 2B, CMRs #2 and #3 in the aforementioned example of Option 2 (Fig. 1C) are associated with two other TCI states #e and #f, and CMR #4 in the aforementioned example of Option 2 is associated with two further TCI states #g and #h. At least one pair of TCI states #a and #b, TCI states #e and #f, and TCI states #g and #h may correspond to two indicated TCI states. In an example variation of option 3 in Fig. 2C, CMRs #2 and #3 in the previous example of option 3 (Fig. 1D) are associated with different TCI states #e and #f, respectively. At least two of TCI states #a, #b, #e, and #f may correspond to two indicated TCI states. According to this embodiment, the UE can properly determine the relationship between the CMR and the TCI state for the CJT. <Embodiment A2> This embodiment mainly relates to case 2. <<A-CSI-RS Resources>> If followUnifiedTCIstate is configured for the A-CSI-RS resource configured as the CMR for CJT, or if an RRC parameter indicating the first or second is configured for each CSI-RS resource or for each CSI-RS resource set, the application of the one or two indicated TCI states may follow at least one of the following options: - Option 1 (case where one indication TCI state applies) The one indication TCI state is N TRP This applies to all CMRs. - Option 2 (case where two indication TCI states apply) The two indication TCI states are set TRP This option may follow at least one of several options 2-x below. -- Option 2-1: Every CMR is associated / QCLed with two DL RSs in the TCI state for QCL type A. -- Option 2-2: All CMRs are associated / QCL'd with two DL RSs in TCI states for QCL type A except for {Doppler shift, Doppler spread} in the second indicated TCI state. - Option 3 (case where two indication TCI states apply) The first of the two indicated TCI states is set. TRP N CMRs, and the second of the two indicated TCI states is set. TRP The association between the CMR and the TCI state may be determined by at least one of several options 3-x below. -- Option 3-1: RRC signaling. For example, an RRC IE may set up an association between a CSI-RS resource and the first or second TCI state. -- Option 3-2: Assumptions by rules or UE. For example, N TRP The first X CSI-RS resources (CMRs) among the N CMRs are associated with the first indicated (activated) TCI state for CJT, TRP The remaining CSI-RS resources (CMRs) among the CMRs may be associated with the second indication (activated) TCI state for CJT. X may be 1 or ceil(N TRP / 2) or floor(N TRP / 2). - Variations Variations based on options 1 / 2 / 3 are possible. One indicating TCI state is N TRP The two indication TCI states may be applied to at least one CMR out of N CMRs (e.g., at least two CMRs in option 3). TRP The option may be applied to at least one CMR from the CMRs (e.g., two CMRs for option 3). <<P / SP-CSI-RS Resources>> The P / SP-CSI-RS resources configured as a CMR for CJT may follow at least one of the following options: - Option a Only for CMR for CJT, the setting of P / SP-CSI-RS resource to follow unified TCI state (followUnifiedTCIstate) is supported. If followUnifiedTCIstate is configured for the P / SP-CSI-RS resource, the P / SP-CSI-RS resource may follow option 1 / 2 / 3 for A-CSI-RS resource described above. - Option B The setting of the P / SP-CSI-RS resource set as the CMR for CJT to follow the unified TCI state (followUnifiedTCIstate) is not supported. The TCI state for the P / SP-CSI-RS resource may be set by the RRC. When the RRC IE sets the TCI state for the P / SP-CSI-RS resource, whether there is a constraint between the CMR and the TCI state / RS may be the same as in the first embodiment. Both the embodiment A1 and the embodiment A2 may be applied to a P / SP / A-CSI-RS CMR. The embodiment A1 and the embodiment A2 may be applied to different CMRs configured with different settings of the time domain behavior of the P / SP / A. According to this embodiment, the UE / base station can appropriately apply the TCI state to the P / SP / A-CSI-RS resources for channel measurement for CJT. <Analysis> As mentioned above, for CJT CSI reporting, it is assumed that up to four CMR configurations are supported, and one CMR is associated with one TRP. It is also assumed that one or two indicated TCI states can be configured for CJT-PDSCH, and no TCI state is configured for PDSCH. The indicated TCI state can be indicated by at least one of the TCI state fields of the RRC, MAC CE, and DCI formats. For CJT CMR, when A / SP / P-CSI-RS is applied, the following may be assumed based on the CSI-RS rules for unified TCI conditions: For A-CSI-RS, a triggering DCI (e.g., a first indicated joint / DL TCI or a second indicated joint / DL TCI (e.g., a second indicated joint / DL TCI) st or 2 nd indicated joint / DL TCI) is selected. For P / SP-CSI-RS, the joint / DL TCI state is configured per CSI-RS resource (or CSI-RS resource set). Therefore, cases are also envisaged where the indicated joint / DL TCI (eg, indicated TCI state) applies only to the A-CSI-RS (or a configuration supporting application to the P / SP-CSI-RS). In this way, when a PDSCH using CJT is set / supported and a CMR for CJT (or a CSI-RS resource for CJT) is set, it is not clear how to control / set the QCL / TCI state for the PDSCH / CMR. Therefore, the following embodiment 0 / embodiment 1 may be applied. <Embodiment 0> Embodiment 0 relates to an example of QCL of PDSCH and CMR in which application of CJT is supported. A PDSCH in which CJT is configured / applied / supported may be QCL'd with at least one (or some / all) of the CMRs for CJT CSI reporting (e.g., CMRs for CJT) (see FIG. 3). Although FIG. 3 shows a case in which two CMRs for CJT CSI reporting (e.g., CMRs for CJT) are configured, the number of CMRs for CJT is not limited to this. The QCL association / restriction may vary based on a predetermined condition. The predetermined condition may include at least one of the following conditions 0-1 to 0-3. In the following description, the indicated TCI state may be read as an indicated joint / DL TCI state or a joint / DL TCI state. [Condition 0-1] The predetermined condition may be the number of indication TCI states for the PDSCH for CJT. When the PDSCH for CJT is indicated in one TCI state, the PDSCH configured for CJT may be QCL'd with all (or at least one) of the CMRs for CJT CSI reporting. When the PDSCH for CJT is indicated with two TCI states, one or both of the TCI states of the PDSCH configured for CJT may be QCL'd with all (or at least one / part) of the CMRs for CJT CSI reporting. [Condition 0-2] The predetermined condition may be the number of CMR resources for CJT reporting. If the number of CMRs is 1, the CMR may be QCL'd with the PDSCH. If the number of CMRs is more than 1, at least some (or at least one) CMR may be QCL'd with the PDSCH. Here, a distinction is made between the case where the number of CMRs is 1 and the case where it is more than 1. As another example, a distinction may be made between the case where the number of CMRs is 2 and the case where it is more than 2 (for example, the number of indicated TCI states of the PDSCH is 2). For example, if the number of CMRs is 2 and the number of indicated TCI states for PDSCH is 2, the two CMRs may be PDSCH and QCL, otherwise, at least some (or at least one) of the CMRs may be PDSCH and QCL. [Condition 0-3] The predefined condition may be the number of TCI states that are set / associated with the CMR resource for CJT reporting. When the number of TCI states configured / associated with a CMR resource for CJT reporting is 1, the PDSCH configured for CJT may be QCL'd with all (or at least one) of the CMRs for CJT CSI reporting. When the number of TCI states configured / associated with a CMR resource for CJT reporting is greater than one (or is multiple), the PDSCH configured for CJT may be QCL'd with a part (or at least one) of the CMR for CJT CSI reporting. Similarly, as another example, a distinction may be made between the case where the number of TCI states of a CMR is 2 and the case where it is greater than 2 (e.g., the number of TCI states indicated for a PDSCH is 2). For example, when the number of TCI states of a CMR is 2, the PDSCH for CJT may be QCLed with all (or at least one) of the CMRs. In other cases, the PDSCH for CJT may be QCLed with some (or at least one) of the CMRs. <Embodiment 1> The first embodiment relates to an example of application / setting of the TCI state when a PDSCH in which application of the CJT is supported and a CMR for reporting the CJT CSI are configured. The first embodiment may be applied alone or in combination with the zeroth embodiment. When the PDSCH is configured for CJT and at least one of the CMRs is configured for CJT CSI reporting, at least one of the following options 1-1 to 1-5 may be applied. [Option 1-1] An indicated TCI state (eg, an indicated joint / DL TCI state) may be applied to the P / SP-CSI-RS. In this case, the configuration shown in embodiment A2 may be applied. [Option 1-2] At least one (or all) of the TCI states of the CMR (e.g., configured / indicated joint / DL TCI state) may be applied to the PDSCH with CJT configured. If the CMR is a P / SP-CSI-RS with a joint / DL TCI state configured, or if the CMR is an A-CSI-RS that is not configured to follow the indicated TCI state, the UE may receive a PDSCH (e.g., a PDSCH for CJT) in the configured TCI state(s). The number of different joint / DL TCI states for a CMR may be limited to a maximum of two (or less than or equal to two). If more than two TCI states are configured across all CMRs, the UE may select up to two TCI states according to a predefined rule or higher layer / RRC configuration. The predefined rule may be, for example, at least one of a lower TCI ID and a TCI associated with a lower CMR / CSI-RS ID. Option 1-2 (or the restriction on the number of different joint / DL TCI states for CMR in Option 1-2) may be applied when the scheduling offset of the PDSCH for CJT is equal to or greater than a predetermined threshold. When the scheduling offset of the PDSCH for CJT is smaller than a predetermined threshold, the UE may buffer the received signal in two indicated TCI states if the UE supports buffering UE capability, and may buffer the received signal in one indicated TCI state if the UE does not support buffering UE capability. The case where the UE buffers a received signal other than the indicated TCI state may not be supported. In this case, as described above, Option 1-2 (or the restriction on the number of different joint / DL TCI states for a CMR in Option 1-2) may be applied when the scheduling offset of the PDSCH for CJT is equal to or greater than a predetermined threshold. That is, when the PDSCH is configured for CJT and at least one of the CMRs is configured for CJT CSI reporting, the UE may not expect / assume to receive the PDSCH for CJT when the scheduling offset is smaller than the threshold. If the CMR is an A-CSI-RS configured to follow the unified TCI state (e.g., followUnifiedTCIState), the UE may receive a PDSCH (e.g., a PDSCH for CJT) in one of the indicated joint / DL TCI states. [Option 1-3] For CMR for CJT, only A-CSI-RS may be supported. The UE may not expect / assume that the P / SP-CSI-RS, the A-CSI-RS that is not configured to follow the indicated TCI state, is configured in the CMR for CJT. This allows the indicated joint / DL TCI state to be easily applied to both the PDSCH for CJT and the CMR for CJT. [Option 1-4] The indicated TCI state applied to the PDSCH may be the same as the configured TCI state of CMR. It is also conceivable that the network (e.g., base station) may indicate the same TCI state ID as the configured TCI state ID for CSI-RS / SP-CSI-RS. The UE may not expect / assume that the indicated joint / DL TCI state applied to PDSCH for CJT is different from the TCI state configured for CSI-RS for CMR. This may mean that the base station cannot update the TCI state indicated by the MAC CE / DCI if it wants to utilize both PDSCH for CJT and CMR for CJT features. [Option 1-5] When the TCI for a CMR is configured by the RRC, some additional TCI states (e.g., candidate TCIs) may also be configured for the CMR by the RRC. In this case, the indication TCI (e.g., the indication TCI applied to the PDSCH) may be the same as one of the configured TCI states of the CMR. The configured TCIs of the CMR may include the candidate TCIs. Similarly, as another example, a distinction may be made between the case where the number of TCI states of a CMR is 2 and the case where it is greater than 2 (e.g., the number of TCI states indicated for a PDSCH is 2). For example, when the number of TCI states of a CMR is 2, the PDSCH for CJT may be QCLed with all (or at least one) of the CMRs. In other cases, the PDSCH for CJT may be QCLed with some (or at least one) of the CMRs. <Additional Information> [Notification of information to UE] In the above-described embodiment, any information may be notified to the UE (from a network (NW) (e.g., a base station (BS))) (in other words, any information is received from the BS by the UE) using physical layer signaling (e.g., DCI), higher layer signaling (e.g., RRC signaling, MAC CE), a specific signal / channel (e.g., PDCCH, PDSCH, reference signal), or a combination thereof.

(Wireless communication system) A 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 of these methods. 4 is a diagram showing an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may simply be 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). In addition, the wireless communication system 1 may support dual connectivity between a plurality of 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)), and the like. 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. The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (e.g., dual connectivity in which both the MN and the SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))). 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 arranged in the macrocell C1 and form a small cell C2 that is narrower than the macrocell C1. A user terminal 20 may be located in at least one of the cells. The arrangement and number of each cell and the user terminal 20 are not limited to the embodiment shown in the figure. Hereinafter, when the base stations 11 and 12 are not distinguished from each other, they will be collectively referred to as a base station 10. 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). 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 frequency band higher than FR2. Furthermore, the user terminal 20 may perform communication in each CC using at least one of Time Division Duplex (TDD) and Frequency Division Duplex (FDD). The multiple base stations 10 may be connected by wire (e.g., optical fiber conforming to the Common Public Radio Interface (CPRI), X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node. 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 at least one of, for example, an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like. The core network 30 may include network functions (Network Functions (NF)) such as, for example, 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 an Operation, Administration and Maintenance (Management) (OAM). Note that a single network node may provide multiple functions. Also, communication with an external network (e.g., the Internet) may be performed via the DN. The user terminal 20 may be a terminal compatible with at least one of communication methods such as LTE, LTE-A, and 5G. In the wireless communication system 1, a wireless access scheme based on Orthogonal Frequency Division Multiplexing (OFDM) may be used.

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. For example, although only one processor 1001 is shown, there may be multiple processors, and the processes may be performed by one processor or by two or more processors simultaneously, sequentially, or in other manners. Additionally, the processor 1001 may be implemented by one or more chips. Each function in the base station 10 and the user terminal 20 is realized, for example, by loading a specified software (program) onto hardware such as a processor 1001 and a memory 1002, so that the processor 1001 performs calculations, controls communications via a communication device 1004, and controls at least one of the reading and writing of data in the memory 1002 and the storage 1003. The processor 1001, for example, operates an operating system to control the entire computer. The processor 1001 may be configured by 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), transmission / reception unit 120 (220), etc. may be realized by the processor 1001.

As the programs, programs that cause a computer to execute at least a part of the operations described in the above-mentioned embodiments are used. For example, the control unit 110 (210) may be realized by a control program stored in the memory 1002 and operated by the processor 1001, and other functional blocks may be realized in a similar manner. The memory 1002 is a computer-readable recording medium, and may be configured by at least one of, for example, a Read Only Memory (ROM), an Erasable Programmable ROM (EPROM), an Electrically EPROM (EEPROM), a Random Access Memory (RAM), and other suitable storage media.

Storage 1003 may also be referred to as an auxiliary storage device. The communication device 1004 is hardware (transmission and reception device) for performing communication 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, a communication module, etc. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., in order to realize at least one of, for example, Frequency Division Duplex (FDD) and Time Division Duplex (TDD). For example, the above-mentioned transmission and reception unit 120 (220), transmission and reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission and 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.

For example, the processor 1001 may be implemented using at least one of these pieces of hardware. (Modification) In addition, the terms described in this disclosure and the terms necessary for understanding this 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 read as mutually interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may be called a pilot, a pilot signal, or the like depending on the applied standard. A component carrier (CC) may also be called a cell, a frequency carrier, a carrier frequency, or the like. 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. Here, the numerology may be a communication parameter applied to at least one of the 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, a specific filtering process performed by the transceiver in the frequency domain, and a specific windowing process performed by the transceiver in the time domain. 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. A slot may include multiple minislots. Each minislot may be composed of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may be composed 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. A radio frame, a subframe, a slot, a minislot, and a symbol each represent a time unit for transmitting a signal. A different name may be used for 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 read as interchangeable with each other. For example, one subframe may be called a TTI, a plurality of consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in the 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, a minislot, or the like, instead of a subframe. Here, TTI refers to, for example, the minimum time unit of 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. The TTI may be a transmission time unit of a channel-coded data packet (transport block), a code block, a code word, etc., or may be a processing unit of scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) in which a transport block, a code block, a code word, etc. are actually mapped may be shorter than the TTI. In addition, 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 of scheduling. Also, the number of slots (minislots) constituting the minimum time unit of scheduling may be controlled. A TTI having a time length of 1 ms may be called a normal TTI (TTI in 3GPP Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a slot, etc. In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length exceeding 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 equal to or greater than 1 ms. 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, and may be, for example, 12. The number of subcarriers included in an RB may be determined based on the numerology. In addition, an RB may include one or more symbols in the time domain and may be one slot, one minislot, one subframe, or one TTI in length. Each of one TTI, one subframe, etc. may be composed of one or more resource blocks. 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. 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. 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 numerology on a carrier, where the common RBs may be identified by the index of the RBs relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP. The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). One or more BWPs may be configured in one carrier for a UE. 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 replaced with "BWP". The above-mentioned 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. In addition, the information, parameters, etc. described in the present disclosure may be represented using absolute values, may be represented using relative values ​​from a predetermined value, or may be represented using other corresponding information. For example, a radio resource may be indicated by a predetermined index. The names used for parameters, etc. in this disclosure are not limiting in any way. Furthermore, the formulas, etc. 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 limiting in any way. The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. For example, the data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof. Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via multiple network nodes. Input and output information, signals, etc. may be stored in a specific location (e.g., memory) or may be managed using a management table.
