Description

Technical Field

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

[0002] In the Universal Mobile Telecommunications System (UMTS) network, Long Term Evolution (LTE) is standardized for the purpose of further high-speed data rate, low latency, etc. (Non-Patent Document 1). In addition, LTE-Advanced (3GPP Rel. 10-14) is standardized for the purpose of further increasing the capacity and sophistication of LTE (Release (Rel.) 8, 9)).

[0003] Successor systems of LTE (also known as, for example, 5th generation mobile communication system (5G), 5G+(plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel.15 and later, etc.) are also being studied.

[0004] Prior art literature

[0005] Non-patent literature

[0006] Non-patent document 1: 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 Summary of the invention

[0007] Problems to be solved by the invention

[0008] In wireless communication systems, one or more cells / transmission / reception points (Transmission / Reception Point (TRP)) (Multi-TRP (MTRP)) are being studied to perform downlink (DL) transmission to terminals (user terminals, user equipment (UE)).

[0009] When multiple TRPs are applied, the serving cell may be switched to a cell (additional cell) having a PCI different from that of the serving cell through signaling of at least one of layer 1 and layer 2 (layer1 / layer2 inter-cell mobility).

[0010] However, when the frequencies of the PCIs are different, it is not clear how the settings related to CSI measurement and reporting (for example, measurement and reporting of L1-RSRP and L1-SINR) in each frequency are performed, and how the measurement or reporting is performed. If the measurement or reporting in multiple frequencies is not performed properly, there is a concern that problems such as reduced communication throughput will occur.

[0011] Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can appropriately perform measurement or reporting in multiple frequencies.

[0012] Means for solving problems

[0013] A terminal involved in one embodiment of the present invention is characterized in that it has: a receiving unit that receives at least one of a channel state information (CSI) report setting and a CSI resource setting indicating one or more frequencies; and a control unit that controls CSI measurement and CSI reporting using reference signals in one or more of the frequencies.

[0014] Effects of the Invention

[0015] According to one aspect of the present disclosure, it is possible to appropriately perform measurement or reporting at a plurality of frequencies. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] (Multiple TRP)

[0046] In NR, one or more transmission / reception points (Transmission / Reception Point (TRP)) (multi TRP (MTRP)) are being discussed to use one or more panels (multi-panels) to perform DL transmission to the UE. In addition, the UE is being discussed to perform UL transmission to one or more TRPs.

[0047] In addition, multiple TRPs may correspond to the same cell identifier (cell identifier (ID)) or to different cell IDs. The cell ID may be a physical cell ID or a virtual cell ID.

[0048] Figures 1A-1D is a diagram showing an example of a multi-TRP scenario. In these examples, it is assumed that each TRP is capable of sending 4 different beams, but is not limited to this.

[0049] Figure 1A An example is shown in which only one TRP (in this example, TRP1) among multiple TRPs transmits to the UE (may also be referred to as single mode, single TRP, etc.). In this case, TRP1 transmits both a control signal (PDCCH) and a data signal (PDSCH) to the UE.

[0050] Figure 1B An example of a situation in which only one TRP (TRP1 in this example) among multiple TRPs sends a control signal to the UE and the multiple TRPs send data signals (also referred to as single-master mode) is shown. The UE receives each PDSCH sent from the multiple TRPs based on one downlink control information (Downlink Control Information (DCI)).

[0051] Figure 1C An example of a situation (also referred to as master-slave mode) in which multiple TRPs each send a portion of a control signal to a UE and the multiple TRPs send data signals is shown. Alternatively, part 1 of the control signal (DCI) may be sent via TRP1, and part 2 of the control signal (DCI) may be sent via TRP2. Part 2 of the control signal may also depend on part 1. The UE receives each PDSCH sent from the multiple TRPs based on these parts of the DCI.

[0052] Figure 1D An example of a situation (also called multi-master mode) in which multiple TRPs each send a separate control signal to the UE and the multiple TRPs send data signals is shown. Alternatively, the first control signal (DCI) may be sent through TRP1, and the second control signal (DCI) may be sent through TRP2. Based on these DCIs, the UE receives each PDSCH sent from the multiple TRPs.

[0053] When using a DCI to schedule Figure 1B In the case of multiple PDSCHs from multiple TRPs (also referred to as multiple PDSCHs), the DCI may also be referred to as a single DCI (S-DCI, single PDCCH). In addition, when multiple DCIs are used to schedule Figure 1D In the case of multiple PDSCHs from multiple TRPs, these multiple DCIs can also be called multi-DCI (M-DCI, multiple PDCCH).

[0054] Different transport blocks (TB) / code words (CW) / different layers can also be sent from each TRP of multiple TRPs. Alternatively, the same TB / CW / layer can also be sent from each TRP of multiple TRPs.

[0055] As a method of multi-TRP transmission, non-coherent joint transmission (NCJT) is being studied. In NCJT, for example, TRP1 performs modulation mapping on the first codeword, performs layer mapping, and uses the first precoding to transmit the first PDSCH for the first number of layers (e.g., 2 layers). In addition, TRP2 performs modulation mapping on the second codeword, performs layer mapping, and uses the second precoding to transmit the second PDSCH for the second number of layers (e.g., 2 layers).

[0056] In addition, multiple PDSCHs (multi-PDSCHs) NCJT can also be defined as partially or completely repeated with respect to at least one of the time domain and the frequency domain. That is, the first PDSCH from the first TRP and the second PDSCH from the second TRP can also be repeated on at least one of the time and frequency resources.

[0057] The first PDSCH and the second PDSCH may also be considered not to be in a quasi-co-location (QCL) relationship. The reception of multiple PDSCHs may also be replaced by the simultaneous reception of PDSCHs that are not of a certain QCL type (eg, QCL type D).

[0058] In URLLC for multiple TRPs, support for PDSCH (transport block (TB) or codeword (CW)) repetition across multiple TRPs is being studied. Support for repetition across multiple TRPs in the frequency domain or layer (spatial) domain or time domain is being studied (URLLC schemes, e.g., schemes 1, 2a, 2b, 3, 4). In scheme 1, multiple PDSCHs from multiple TRPs are space division multiplexing (SDM). In schemes 2a and 2b, PDSCHs from multiple TRPs are frequency division multiplexing (FDM). In scheme 2a, the redundancy version (RV) is the same for multiple TRPs. In scheme 2b, the RVs can be the same or different for multiple TRPs. In schemes 3 and 4, multiple PDSCHs from multiple TRPs are time division multiplexing (TDM). In scheme 3, multiple PDSCHs from multiple TRPs are sent in one time slot. In Scheme 4, multiple PDSCHs from multiple TRPs are sent in different time slots.

[0059] Based on such a multi-TRP scenario, more flexible transmission control using channels with good quality can be performed.

[0060] NCJT using multiple TRPs / panels may use high rank. In order to support ideal and non-ideal backhaul between multiple TRPs, it is also possible to support single DCI (single PDCCH, for example, Figure 1B ) and multiple DCI (multiple PDCCH, e.g. Figure 1D ) For both single DCI and multi-DCI, the maximum number of TRPs can also be 2.

[0061] For single PDCCH design (mainly for ideal backhaul), the extension of TCI is being studied. Each TCI code point in DCI can also correspond to 1 or 2 TCI states. The TCI field size can also be the same as the TCI field size of Rel.15.

[0062] (L1 / L2 inter-cell mobility)

[0063] As described above, the UE is studying UL transmission to one or more cells / TRPs. As a step in this case, consider the following scenario 1 or scenario 2. In addition, in the present disclosure, the serving cell may also be rewritten as the TRP within the serving cell. Layer 1 / layer 2 (layer1 / layer2 (L1 / L2)), DCI / Media Access Control Control Element (MAC CE)) may also be rewritten with each other. In the present disclosure, a PCI that is different from the physical cell ID (Physical Cell Identity (PCI)) of the current serving cell is sometimes abbreviated as "different PCI". Non-serving cells, cells with different PCIs, and additional cells may also be rewritten with each other.

[0064] <Scene 1>

[0065] Scenario 1 may correspond to, for example, inter-cell mobility of multiple TRPs, or may not correspond to a scenario of inter-cell mobility of multiple TRPs.

[0066] (1) The UE receives from the serving cell the configuration of the SSB for beam measurement of the TRP corresponding to the PCI different from that of the serving cell, and the configuration of the resources of the different PCI required for using the wireless resources for data transmission and reception.

[0067] (2) The UE performs beam measurement of TRPs corresponding to different PCIs and reports the beam measurement results to the serving cell.

[0068] (3) Based on the above report, the Transmission Configuration Indication (TCI) state associated with the TRP corresponding to the different PCIs is activated through L1 / L2 signaling from the serving cell.

[0069] (4) The UE uses a UE-dedicated channel on a TRP corresponding to a different PCI for transmission and reception.

[0070] (5) Including the case of multiple TRPs, the UE needs to always cover the serving cell. As in the existing system, the UE needs to use common channels (Broadcast Control Channel (BCCH), Paging Channel (PCH)) from the serving cell.

[0071] In scenario 1, when the UE sends or receives signals to the additional cell / TRP (the TRP corresponding to the PCI of the additional cell), the serving cell (the assumption of the serving cell in the UE) is not changed. The UE is set with high-level parameters associated with the PCI of the non-serving cell from the serving cell. Scenario 1 can also be applied in Rel.17, for example.

[0072] Figure 2A This is a diagram showing an example of UE movement in Rel.17. Assume that the UE moves from a cell of PCI#1 (serving cell) to a cell of PCI#3 (additional cell) (which overlaps with the serving cell). In this case, in Rel.17, the serving cell is not switched via L1 / L2. The additional cell is a cell with an additional PCI that is different from the PCI of the serving cell. The UE can receive / send UE-dedicated channels from the additional cell. In order to receive UE common channels (e.g., system information / paging / short message), the UE needs to be within the coverage of the serving cell.

[0073] <Scene 2>

[0074] In scenario 2, L1 / L2 inter-cell mobility is applied. In L1 / L2 inter-cell mobility, it is possible to change the serving cell by using functions such as beam control without resetting RRC. In other words, it is possible to transmit and receive with the additional cell without handover. Since RRC reconnection is required for handover, there will be a period when data communication cannot be performed. Therefore, by applying L1 / L2 inter-cell mobility that does not require handover, data communication can continue even when the serving cell is changed. Scenario 2 can also be applied in Rel.18, for example. In scenario 2, for example, the following steps are performed.

[0075] (1) The UE receives the SSB configuration of a cell (additional cell) having a different PCI from the serving cell for beam measurement / changing the serving cell.

[0076] (2) The UE performs beam measurement of cells using different PCIs and reports the measurement results to the serving cell.

[0077] (3) The UE may also receive the configuration of a cell with a different PCI (serving cell configuration) through higher layer signaling (e.g., RRC). In other words, a pre-configuration related to the serving cell change may also be performed. This configuration may be performed together with the configuration in (1) or separately.

[0078] (4) Based on the above report, the TCI state of the cell with a different PCI may be activated by L1 / L2 signaling according to the change of the serving cell. The activation of the TCI state and the change of the serving cell may also be performed separately.

[0079] (5) The UE changes the serving cell (as if the serving cell were in use) and starts receiving / transmitting using a preset UE-dedicated channel and TCI state.

[0080] That is, in scenario 2, the serving cell (the assumption of the serving cell in the UE) is updated through L1 / L2 signaling. Scenario 2 can also be applied in Rel.18.

[0081] Figure 2B 18. In Rel. 18, the serving cell is switched by L1 / L2. The UE can receive / transmit UE-specific channels / common channels with the new serving cell. The UE can also be excluded from the coverage of the previous serving cell.

[0082] (Setting of multiple candidate cells)

[0083] Figure 3 This is a diagram showing an example of the association between a serving cell and a candidate cell. Assume that SpCell#0, SCell#1, or SCell#2 is a serving cell. In addition, SpCell means a special cell (including a primary cell (PCell) and a primary secondary cell (PSCell)). SCell means a secondary cell. SpCell#0 is associated with candidate cell#0-1, candidate cell#0-2, and candidate cell#0-3. SCell#1 is associated with candidate cell#1-1. SCell#2 is associated with candidate cells#2-1 and 2-2. In this way, a serving cell may also be associated with more than one candidate cell (candidate serving cell).

[0084] Regarding the setting of cells that are candidates for changing the serving cell (candidate cells), for example, the following options 1 and 2 are considered.

[0085] <Option 1>

[0086] The information in ServingCellConfig may include information on multiple candidate cells, as in the inter-cell mobility of Rel. 17. In this case, multiple candidate cells need to share the same settings of PDCCH / PDSCH / UL, etc. with the serving cell.

[0087] For example, in the inter-cell mobility of Rel.17, the addition of "mimoParam-r17" under ServingCellConfig and the addition of PCI setting information ( Figure 4A , Figure 4B ). This framework is applied to the case where cells with different PCIs share the same PDCCH / PDSCH / UL, etc. settings.

[0088] For each candidate cell, more settings such as LTE CRS mode, RACH settings, etc. can also be applied. In addition, by also considering the cell-specific CSI-RS settings (for CSI / TRS), different CSI-RS opportunities / resources can be set for each cell to reduce interference.

[0089] Figure 4A is a diagram showing a first example of ServingCellConfig for Option 1. Figure 4A ServingCellConfig includes settings for additional cells (each candidate cell). Figure 4B is a diagram showing a second example of ServingCellConfig for Option 1. Figure 4B ServingCellConfig includes the settings of additional cells (candidate cells) for L1 / L2 inter-cell mobility. Figure 4A For example, it corresponds to the above scenario 1. Figure 4B For example, it corresponds to the above scenario 2.

[0090] like Figure 4A , Figure 4B , the candidate cells are pre-set via RRC. As the initial state, the candidate cells can be fixed as activated / deactivated in the specification or set as activated / deactivated via RRC. Furthermore, the candidate cells for L1 / L2 cell switching can also be activated / deactivated via MACCE. The L1 / L2 cell switching indication can also be sent only from the cell from the activated cell.

[0091] <Option 2>

[0092] Multiple candidate cells may also be applied with complete settings corresponding to each cell (e.g., ServingCellConfig), or the carrier aggregation (CA) setting framework may be reused to associate with each serving cell. Since the UE is provided with complete settings for each candidate cell, it can communicate appropriately with the candidate cell.

[0093] In the CA setting framework, SpCell is set for each cell group, and multiple SCells can be added. Alternatively, by reusing the CA framework, a serving cell can be set for each cell group of L1 / L2 inter-cell mobility, and multiple candidate cells can be set ( Figure 5 ). The candidate cell can also be activated / deactivated through MAC CE. This method is considered to be helpful in reducing the complexity of UE operation. As an example, the CellGroupConfig of cell group ID0 is shown.

[0094] Fig. 6Ais a diagram showing a second example of Option 2. Fig. 6A In the example of , a common candidate cell pool for cell switching in MCG / SCG is applied to candidate cells. That is, candidate cells are treated as a pool (group) regardless of frequency band.

[0095] Figure 6B is a diagram showing a third example of Option 2. Figure 6B In the example, multiple cell groups are set, and cell group switching can be performed through L1 / L2 signaling. Candidate cells are set for each cell group, and the setting of each group includes the index of the corresponding SpCell and SCell. Figure 6B In the figure, the CellGroupConfig of the cell group ID: 1 is shown as an example.

[0096] (Signaling for serving cell change indication)

[0097] The implicit or explicit signaling used for serving cell change indication is described.

[0098] [Method 1]

[0099] In method 1, implicit signaling for indicating a serving cell change is described.

[0100] [[Option 1-1]]

[0101] In the case where a specific control resource set (Control Resource Set (CORESET)) (for example, at least one of CORESET#0, CORESET of CH5Type0-CSS, CORESET of CH6 / CH7 / CH8 CSS) and one or more TCI states associated with a cell with a PCI different from that of the serving cell are indicated (activated) through MAC CE (for a specific CORESET, one or more TCI states associated with a cell with a PCI different from that of the serving cell are indicated / activated through MAC CE), the UE may also determine that the serving cell is changed to another cell (cell x, a cell with a different PCI). That is, the activation may also implicitly indicate that the serving cell is changed to another cell.

[0102] In this case, the UE may also update the beams of other CORESET IDs, other CORESETs using CH6 / CH7 / CH8, or other CORESETs using CSS to the same TCI state as the above-mentioned activated TCI state.

[0103] [[Option 1-2]]

[0104] When MAC CE activates / deactivates the TCI state of PDSCH, when all the TCI states activated by MAC CE are associated with the same cell x having a PCI different from the PCI of the serving cell, the UE may also determine that the serving cell is changed to another cell (cell x). That is, the association may also implicitly indicate that the serving cell is changed to another cell.

[0105] In the case of applying this option, when the NW (base station) does not change the serving cell, when the MAC CE activates the TCI state of the PDSCH associated with a cell with a different PCI, it needs to also include the TCI state associated with other cells (for example, the current serving cell or a cell with a second different PCI).

[0106] [[Option 1-3]]

[0107] MAC CE activates / deactivates the unified TCI state (e.g., corresponding to the unified TCI framework of Rel.17), and when all activated unified TCI states are associated with the same cell x with different PCIs, the UE may also determine that the serving cell is changed to another cell (cell x). That is, the association may also implicitly indicate that the serving cell is changed to another cell.

[0108] [Method 2]

[0109] In method 2, explicit signaling for indicating a serving cell change is described. Method 2 is applied to, for example, scenario 2 described above.

[0110] [[Option 2-1]]

[0111] In the following, an example of a serving cell change indication is described. In addition, activation / deactivation of a non-serving cell, change of a serving cell, and transmission / reception with another cell (non-serving cell) having a physical cell ID different from that of the serving cell may also be mutually rewritten.

[0112] The UE may also receive a new MAC CE for activation / deactivation of a non-service cell, which includes at least one of the following fields (1) to (3) (information) corresponding to the non-service cell. Upon receiving the MAC CE, the UE may also determine that the service cell is changed to another cell (non-service cell). In addition, the UE may also control the sending and receiving of DL signals / UL signals with the non-service cell based on the information. In addition, the non-service cell may be one or more. In the example shown below, a MAC CE including multiple fields representing multiple non-service cell indexes is applied.

[0113] (1) Service cell ID.

[0114] (2) BWP ID.

[0115] (3) Non-serving cell ID for activation: The non-serving cell ID may be replaced with any information corresponding to the non-serving cell (that can identify the non-serving cell).

[0116] As the example of (3), any one of (3-1) to (3-5) may be applied.

[0117] (3-1) PCI (PCI used directly) For example, 10 bits are used.

[0118] (3-2) Re-indexing of non-serving cells (new IDs). The new ID may be associated with a part of the PCI and set only for the serving cell and non-serving cell used (usable) by the UE. The new ID can reduce the number of bits more than the PCI.

[0119] (3-3) CSI report configuration ID (CSI-ReportConfigId) (when CSI-ReportConfig corresponds to one or more non-serving cells).

[0120] (3-4) CSI resource configuration ID (CSI-ResourceConfigId) (when CSI-ResourceConfigId corresponds to one or more non-serving cells).

[0121] (3-5) A bitmap showing activation / deactivation of each non-serving cell. The size (number of bits) of the bitmap may be the same as the number of non-serving cells set on the CC. For example, when activating the second non-serving cell among three non-serving cells, "010" is set.

[0122] At least one of the information included in the MAC CE may also be included in the DCI. Alternatively, at least one of the service cells activated by the MAC CE may also be indicated by the DCI. The MAC CE / DCI may also include a field indicating the TCI status / SSB / CSI-RS from a cell with a different PCI so that the DL beam monitored by the UE can be identified on the target cell (changed service cell). The UE may also use the TCI status / SSB / CSI-RS to make a beam report (CSI report) and send it.

[0123] [[Option 2-2]]

[0124] The UE may also receive a MAC CE in which a new 1-bit field "C" is added to the existing MAC CE. This field indicates whether to change the serving cell. The UE may also receive the MAC CE and determine whether to change the serving cell to another cell based on this field.

[0125] [[Option 2-3]]

[0126] For the MAC CE in option 2-2, further, fields representing the service cell index / PCI / other IDs (such as the new ID of option 2-1 mentioned above) and fields representing the TCI status / SSB / CSI-RS of the target cell (changed service cell) may be included in the MAC CE.

[0127] In this way, the indication for the serving cell change indication is indicated through MAC CE / DCI, so the UE can appropriately change the serving cell.

[0128] [Serving cell switching example 1]

[0129] Figure 7 1 is a diagram showing a service cell switching example 1. For example, in the service cell SpCell#0 of the MCG / SCG, when the service cell is instructed to be changed to the candidate cell #0-2 through L1 / L2 signaling, the candidate cell #0-2 becomes the new service cell SpCell#0. In addition, for example, in the service cell SCell#2 of the MCG / SCG, when the service cell is instructed to be changed to the candidate cell #2-1 through L1 / L2 signaling, the candidate cell #2-1 becomes the new service cell SCell#2.

[0130] [Serving cell switching example 2]

[0131] RRC / MAC CE can set a global candidate cell ID (cell#0, ..., 5) for each cell group, each frequency band, each FR, and each UE. The UE can also be instructed to switch the serving cell based on the global candidate cell ID.

[0132] Figure 8 FIG. 2 is a diagram showing a serving cell switching example 2. Fig. 6A Similarly, a pool of multiple candidate cells is set, and the serving cell can be switched to any (activated) candidate cell in the pool through L1 / L2 signaling. In this case, the set candidate cell can be either SpCell or Sell based on L1 / L2 signaling.

[0133] The UE may receive an indication of a change of the serving cell (from cell #2-1 to candidate cell 4) through MAC CE / DCI. Then, the indicated candidate cell #4 becomes the SpCell of the new cell group.

[0134] [Serving cell switching example 3]

[0135] RRC / MAC CE can set a global candidate cell ID (cell#0-1, #0-1, ..., 2-2) for each cell group, each frequency band, each FR, and each UE. The UE can also be instructed to switch the serving cell through the global candidate cell ID.

[0136] Fig. 9 3 is a diagram showing example 3 of serving cell switching. The UE receives an indication of a serving cell change (from cell #2-0 to cell #2-1) through MAC CE / DCI. And the indicated cell #2-1 becomes the SpCell of the new cell group. In addition, the cells (cell #0-0, cell #1-0) of the same cell group as the indicated cell #2-1 become Scell ​​#1 and Scell ​​#2. That is, the serving cell group is switched.

[0137] (CSI report settings)

[0138] Fig.10 This is a diagram showing an overview of the CSI reporting configuration of RRC. Fig.10 The CSI report setting of RRC in 3GPP Rel.17 is shown. Fig.10 As shown, the CSI report configuration (CSI-ReportConfig) includes "resourcesForChannelMeasurement", "csi-IM-resourcesForInterference", "nzp-CSI-RS-resourcesForInterference", "Report quantity", etc. "resourcesForChannelMeasurement", "csi-IM-resourcesForInterference", "nzp-CSI-RS-resourcesForInterference" correspond to the CSI resource configuration "CSI-ResourceConfig".

[0139] Fig.11 FIG. 1 is a diagram showing a portion of the CSI resource configuration of Rel.17. Fig.11As shown, "csi-SSB-ResourceSetList" is included in the CSI resource configuration (CSI-ResourceConfig). "csi-SSB-ResourceSetList" is a reference list of SSB resources used for CSI measurement and reporting in the CSI-RS resource set. "csi-SSB-ResourceSetListExt-r17" is used to add elements to "csi-SSB-ResourceSetList" when the number of reporting groups (nrofReportedGroups-r17) is set through the CSI report configuration.

[0140] Fig.12 FIG. 1 is a diagram showing a portion of a CSI-SSB resource set of Rel.17. Fig.12 As shown, "servingAdditionalPCIList-r17" is included in the CSI-SSB-ResourceSet. "servingAdditionalPCIList-r17" indicates the physical cell ID (PCI) of the SSB included in the csi-SSB-ResourceList. When this parameter exists, the list has the same number of elements as the csi-SSB-ResourceList. The first entry of the list indicates the value of the PCI for the first entry of the csi-SSB-ResourceList, the second entry of the list indicates the value of the PCI for the second entry of the csi-SSB-ResourceList, and the same is true for the following entries.

[0141] For each entry, when the value is zero, the PCI is the PCI of the serving cell in which the CSI-SSB-ResourceSet is defined. Otherwise (when the value of each entry is other than zero), the value of each entry is additionalPCIIndex-r17 of SSB-MTC-AdditionalPCI-r17 in additionalPCIList-r17 of the serving cell setting (ServingCellConfig), and the PCI is additionalPCI-r17 of the SSB-MTC-AdditionalPCI-r17.

[0142] Fig.13This is a diagram showing settings related to L3 measurement / reporting of Rel.17. associatedMeasGapSSB-r17 indicates an associated measurement gap for SSB measurement identified by ssb-ConfigMobility of a measurement object. When multiple MeasObjectNRs with the same SSB frequency are set, the network sets the same measurement gap ID in this field for each MeasObjectNR. If this field does not exist, the associated measurement gap is a gap set via gapFR1, gapFR2, or gapUE.

[0143] associatedMeasGapCSIRS-r17 indicates an associated measurement gap for CSI-RS measurement identified by csi-rs-ResourceConfigMobility of the measurement object. If this field is not present, the associated measurement gap is a gap configured via gapFR1, gapFR2, or gapUE.

[0144] <Enhancement of L1 measurement reports for L1 / L2 inter-cell mobility>

[0145] When the RS (mainly SSB) of the serving cell and non-serving cell are set in the same CSI reporting setting (or the same CSI resource setting), the UE can add several indicators representing the serving / non-serving cells in addition to the existing reporting content for reporting.

[0146] When new RRC parameters are set, the UE may report the L3-RSRP value (per beam / cell / multi-beam) in addition to the SSB index / CRI and L1-RSRP / L1-SINR values.

[0147] <Event-triggered L1 beam reporting for L1 / L2 inter-cell mobility>

[0148] One or more existing events used for RRM in TS38.331 may be reused to trigger non-periodic L1 beam reporting. One or more new / separate events may be defined to trigger non-periodic L1 beam reporting. L1 beam reporting may also be triggered by any combination of two or more events. The event may also be any one of the following events A2 to A6 and I1. In events A2 to A6, the measurement result may also be at least one measurement result of RSRP (L1-RSRP / L3-RSRP), RSRQ, and SINR (RS-SINR).

[0149] Event A2: The measurement result of the serving cell is worse than the threshold.

[0150] Event A3: The measurement result of the neighboring cell (the measurement result to which the offset value is added) is better than the measurement result of the SpCell (the measurement result to which the offset value is added).

[0151] Event A4: The measurement result of the neighboring cell (to which the offset value is added) is better than the threshold.

[0152] Event A5: The measurement result of the SpCell is worse than the first threshold, and the measurement result of the neighboring cell (the measurement result is added with an offset value) is better than the second threshold.

[0153] Event A6: The measurement result of the neighboring cell (the measurement result to which the offset value is added) is better than the measurement result of the serving cell (Secondary Cell (SCell)) (the measurement result to which the offset value is added).

[0154] Event I1: The interference measurement result is higher than the threshold.

[0155] (analyze)

[0156] As described above, when multiple TRPs are applied, the serving cell may be switched to a cell (additional cell) having a PCI different from that of the serving cell through signaling of at least one of layer 1 and layer 2 (L1 / L2 inter-cell mobility).

[0157] However, when the frequencies of the PCIs are different, it is not clear how the settings related to CSI measurement and reporting (e.g., measurement and reporting of L1-RSRP and L1-SINR) in each frequency are performed, and how the measurement and reporting are performed. If the measurement and reporting in multiple frequencies are not performed properly, there is a concern that problems such as a decrease in communication throughput will occur.

[0158] Therefore, the inventors of the present invention have conceived a terminal, a wireless communication method, and a base station in which measurement and reporting on a plurality of frequencies are appropriately performed.

SSB, SSB index, and SSBRI may also be replaced with each other.

[0172] (Wireless Communication Method)

[0173] <Analysis 1>

[0174] In inter-cell mobility, the switching of SpCell / SCell to candidate cells of any frequency is supported, so it is preferable to correspond to L1 beam measurement (inter-frequency measurement) of multiple frequencies. However, L1 beam measurement / reporting based on the existing CSI report configuration only supports the configuration of RS of the same frequency as the serving cell.

[0175] Fig.14 is a diagram showing examples of RSRP values ​​in multiple frequencies. Fig.14The case where different RSRP values ​​(RSRP value#0-1, 1-1, 2-1) are measured for cells (SpCell#0, SCell#1, SCell#2) of different frequencies is shown. In such a case, it is not clear how the settings related to L1 beam measurement / reporting are performed and how the measurement / reporting is performed. Therefore, the inventors of the present invention have conceived a method of measuring / reporting L1 beams in one or more frequencies.

[0176] <First Embodiment>

[0177] In this embodiment, in order to support the frequency setting for L1 beam measurement (CSI measurement) using a reference signal (RS) (SSB / CSI-RS), an extension of the L1 measurement / report setting is described. For example, the UE may receive at least one of a channel state information (CSI) report setting and a CSI resource setting indicating one or more frequencies, and control the CSI measurement and CSI report using one or more reference signals (RS) in the frequency.

[0178] [Option 1]

[0179] At least one of the CSI report setting (CSI-ReportConfig) and the CSI resource setting (CSI-ResourceConfig) may also include a frequency setting (e.g., Absolute radio-frequency channel number (ARFCN)-ValueNR) corresponding to a reference signal for measurement (e.g., SSB / CSI-RS). ARFCN-ValueNR is used to indicate the ARFCN of the NR global frequency raster applied to the downlink, uplink, or bidirectional (TDD). Each CSI report setting / CSI resource setting corresponds to a frequency. In order to support L1 beam measurement / reporting in multiple frequencies, multiple CSI report settings are required. When ARFCN-ValueNR does not exist in the CSI report setting, it may also mean the same frequency as the current serving cell setting.

[0180] Fig.15 1 is a diagram showing an example of CSI-SSB-ResourceSet of Option 1 of the first embodiment. CSI-SSB-ResourceSet is included in CSI report configuration and CSI resource configuration. Fig.15 The setting of the SSB frequency (ssbFrequency) corresponding to ARFCN-ValueNR is included.

[0181] [Option 2]

[0182] In at least one of the CSI report setting and the CSI resource setting, it is also possible to support setting different frequencies for each SSB / CSI-RS / PCI (e.g., ARFCN-ValueNR). Each CSI resource setting / each CSI report setting can also support L1 beam measurement / reporting in multiple frequencies. In this case, the comparison of RSRP is an intra-frequency comparison, so it is necessary to enrich the beam report quantity setting and beam selection rules. The comparison between frequencies is usually performed based on SINR / RSRQ. SINR / RSRQ is described in the second embodiment described later.

[0183] Fig.16 1 is a diagram showing an example of CSI-SSB-ResourceSet of Option 2 of the first embodiment. CSI-SSB-ResourceSet is included in CSI report configuration and CSI resource configuration. Fig.16 It includes the SSB frequency list (ssbFrequencyList-r18) and the SSB frequency setting (ssbFrequency).

[0184] The frequency used for beam measurement / reporting may also be set / indicated via MAC CE / DCI. For example, a list of multiple frequencies may be set via RRC (CSI report setting / CSI resource setting), and one or more frequencies in the list may be set / indicated via MAC CE / DCI. The multiple frequencies may also be the frequencies of the serving cell and the candidate cell.

[0185] According to this embodiment, one or more frequencies used for beam measurement / reporting can be appropriately set.

[0186] <Second Embodiment>

[0187] In the second embodiment, the case where the CSI resource setting / CSI report setting supports L1 beam (CSI) measurement / reporting in multiple frequencies is described. The UE receives the setting / indication indicating RS (SSB / CSI-RS) received in multiple frequencies in the CSI resource setting / CSI report setting, and uses the RS to perform CSI (L1-RSRP / L1-SINR) measurement and reporting.

[0188] The UE may also control (or send) the sending of a CSI report including both the reference signal received power (Reference Signal Received Power) (L1-RSRP) of layer 1 and the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio) (L1-SINR) of layer 1. The UE may also control (or send) the sending of a CSI report including the measurement results of CSI (L1-RSRP / L1-SINR) in multiple frequencies.

[0189] In order for the UE to report both L1-RSRP and L1-SINR for the beam index, the reporting quantity can also be set for both L1-RSRP and L1-SINR. The beam with the largest L1-RSRP and L1-SINR can be configured at the beginning of the beam report, or it can be explicitly stated. Differential quantization can also be performed for each of the L1-RSRP value and the L1-SINR value. The UE can compare the L1-RSRP of each frequency to select the beam for reporting.

[0190] Fig.17 : is a diagram showing an example of CSI reporting according to the second embodiment. Fig.17 In the example, the CSI report includes the absolute value of the maximum L1-RSRP (L1-RSRP#1) and the difference values ​​from the absolute value (Differential RSRP#2, #3, #4). In addition, the CSI report includes the absolute value of the maximum L1-SINR (L1-SINR#3) and the difference values ​​from the absolute value (Differential RSRP#1, #2, #4). In addition, the CSI report includes an indication of the beam with the maximum L1-SINR at the beginning (row 1). In this example, beam #3 is indicated as the beam with the maximum L1-SINR.

[0191] When measuring RS in multiple frequencies and selecting the reported beam, the UE first compares the L1-RSRP of the same frequency, and then compares the L1-SINR between different frequencies. Alternatively, the UE may first compare the L1-SINR between different frequencies, and then compare the L1-RSRP of the same frequency.

[0192] Fig.18 is a diagram showing an example of beam reporting for multiple frequencies. Fig.18In the example, beam reporting is performed for cells with different frequencies (SpCell#0, SCell#1, SCell#2). In this example, there are 64 beams (SSBs) per cell, so the UE measures the L1-RSRP and L1-SINR of 64×3 beams. In this example, it is assumed that the L1-RSRP of SSB#3 of Scell#1 is the highest, and the L1-RSRP of SSB#1 of SpCell#0 is the second highest. The UE reports the absolute value of the L1-RSRP of SSB#3 of Scell#1 and the difference between the L1-RSRP of SSB#1 of SpCell#0.

[0193] For RS / Cell configured by CSI reporting configuration, for example, in SpCell, all candidate cells for serving cell switching may be configured in CSI reporting configuration during L1 measurement. Furthermore, NW (base station) may determine whether to perform cell switching based on L1 measurement and reporting results.

[0194] The CSI report may include information indicating the frequency at which the RS to be measured for L1-RSRP / L1-SINR is transmitted or PCI.

[0195] According to this embodiment, both L1-RSRP and L1-SINR can be reported in one CSI report. In addition, in one CSI report, CSI measurement results (L1-RSRP / L1-SINR) of multiple frequencies can be reported. Interference varies according to frequency (CC), so L1-SINR becomes a different value. According to this embodiment, L1-SINR of different frequencies can be reported, so NW can grasp the L1-SINR of the candidate cell of the handover, for example.

[0196] When the first / second embodiment is used for L1 measurement / reporting configuration between cells, the structure of STMC and MG configured for frequency, PCI, RS specific to PCI, UE, and CSI resources may be added to the CSI report configuration.

[0197] <Third Embodiment>

[0198] The UE may also receive configuration information for measurement / reporting of layer 3 (L3) including configuration for beam (CSI) measurement / reporting based on layer 1 (L1) reference signal (SSB / CSI-RS). Furthermore, the UE may also control measurement / reporting of L1 and L3 based on the configuration information. For example, Fig.13 As shown, the configuration information related to L3 measurement / reporting, namely MeasObjectNR, may also include frequency configuration for RRM measurement (eg, ARFCN-ValueNR).

[0199] [Option 1]

[0200] The configuration information (MeasObjectNR) related to L3 measurement / reporting may also include an indication indicating whether it is for past L3 RRM measurement or L1 beam measurement. When L1 beam measurement is indicated, the configuration information may further include any configuration (e.g., report quantity) for L1 measurement / reporting in the CSI report configuration.

[0201] [Option 2]

[0202] The configuration information (MeasObjectNR) related to an L3 measurement / report may also include the configuration of multiple frequencies and PCI / RS corresponding to different frequencies for L1 beam measurement / report. The L1 measurement result and the L3 measurement result may be configured to be reported in separate CSI reports or in one CSI report.

[0203] [CSI Report]

[0204] The UE may also report the L3 measurement results (L3-RSRP value for each beam / each cell / each multi-beam) in the inter-frequency (multi-frequency) L1 beam report (CSI report). Alternatively, the UE may also report the L1 measurement results in the L3 measurement result report. The UE may also report the L1 measurement results in the RRC IE or MAC CE.

[0205] Inter-frequency (multiple-frequency) L1 measurement / reporting may also be set as an event trigger. For example, when a specific event occurs, the UE may perform inter-frequency (multiple-frequency) L1 measurement / reporting.

[0206] As a variation, the UE may receive configuration information (CSI report configuration / CSI resource configuration) for beam measurement / reporting based on L1 SSB / CSI-RS, including configuration for measurement / reporting of layer 3 (L3).

[0207] According to this embodiment, the settings of layer 1 and layer 3 can be integrated, and signaling overhead can be suppressed. When this embodiment is used for the setting of L1 measurement / report between cells, the settings of STMC and MG for L3 measurement of MeasObjectNR can be reused for L1 measurement.

[0208] <Analysis 2>

[0209] In order to support L1 inter-frequency measurements for inter-cell mobility, the following scenarios need to be considered.

[0210] [Scenario 1]

[0211] UE antenna cannot simultaneously correspond to L1 measurements in different frequencies ( Fig.19 ). The UE antenna can perform L1 measurements on one frequency at a time. In addition, Fig.19 The Freq. in FIG. means frequency. The same is true in other drawings.

[0212] [Scenario 2]

[0213] RSs from cells of different PCIs (either of the same or different frequencies) used for L1 measurements are not synchronized ( Fig. 20 ).like Fig. 20 For example, there may also be timing gaps between SSBs of cells with different PCIs.

[0214] [Scenario 3]

[0215] RSs from cells with different PCIs (either the same or different frequencies) used for L1 measurements are not aligned ( Fig.21 )(Example: different SSB settings). Fig.21 , the timing of SSB of cells with different PCIs may also be different.

[0216] <Measurement requirements and scheduling restrictions related to L1 measurement>

[0217] [Measurement report requirements]

[0218] The UE sends L1-RSRP reports only for reporting configurations configured relative to the activated BWP.

[0219] [CSI-RS and SSB measurement restrictions in L1-RSRP measurement]

[0220] The UE is required to be able to measure the SSB and CSI-RS of L1-RSRP without measurement gaps. The UE is required to perform SSB and CSI-RS measurements with specific measurement restrictions.

[0221] [Scheduling restrictions for UEs performing L1-RSRP measurements on FR2]

[0222] When the RS used for L1-RSRP measurement meets specific conditions such as the TCI state activated by PDCCH / PDSCH is QCL and is the CSI-RS that is not repeatedly ON in the CSI-RS resource set, there may be no scheduling restrictions on L1-RSRP measurement based on CSI-RS.

[0223] When the above-mentioned specific conditions are met, in a non-HST scenario, when the reference codeword that is the measurement object of FR2-1 or L1-RSRP is not 480kHzSCS or 960kHzSCS of FR2-2, the UE may not expect the transmission of PUCCH / PUSCH / SRS and the reception of CQI of PDCCH / PDSCH / tracking / CSI-RS in at least one of the following codewords (1) to (4).

[0224] (1) The symbol corresponding to the SSB index set for L1-RSRP measurement.

[0225] (2) A symbol corresponding to a periodic CSI-RS resource set for L1-RSRP measurement.

[0226] (3) The symbol corresponding to the semi-persistent CSI-RS resource configured for L1-RSRP measurement when the resource is activated.

[0227] (4) When reporting is triggered, it is set to the symbol corresponding to the aperiodic CSI-RS resource for L1-RSRP measurement.

[0228] <Fourth Embodiment>

[0229] Regarding L1 measurement / reporting for inter-cell mobility, at least one of the following UE capabilities (1) to (5) may be introduced. The process of the present disclosure may be applied only to UEs that report the following UE capabilities or support the specific UE capabilities.

[0230] (1) L1 measurement is supported simultaneously in physical cell IDs (PCIs) of different frequencies. If supported, the UE may also report at least one of the supported frequency numbers and PCI numbers.

[0231] (2) Support L1 measurement in asynchronous PCIs of the same / different frequencies. If supported, the UE may also report at least one of the maximum asynchronous timing difference / gap and the PCI number.

[0232] (3) Supporting L1 measurement in PCIs with asynchronous SSBs configured with the same or different frequencies. If supported, the UE may report at least one of the maximum number of SSB configurations and the PCI number.

[0233] (4) Support L1 measurement with synchronization and full SSB configuration in PCI in the same / different frequencies. If supported, the UE may also report at least one of the PCI number and the frequency number. This may also be the default UE capability for inter-cell mobility L1 measurement / reporting for Rel.18.

[0234] (5) In the case of FR2, L1 measurement of different QCL Type D beams from different PCIs in the same / different frequencies is supported. This can support multi-panel UEs, and each UE panel can measure beams.

[0235] <Fifth Embodiment>

[0236] The UE may also receive the setting of the Measurement Timing Window (MTW) ​​for L1 measurement corresponding to a specific frequency, a specific PCI, and a specific RS (e.g., an RS from a specific PCI), and perform L1 (L1-RSRP / L1-SINR) measurement / reporting based on the setting. Different MTWs may be set for each frequency / each PCI / each RS for different (multiple) frequencies and at least one of different (multiple) PCIs / RSs. The MTW setting may also include a period and offset (periodicityAndOffset) and a duration (duration), and may be the same as the setting of SMTC / SSB-MTC / MG. The UE may also perform layer 1 (L1-RSRP / L1-SINR) measurements during the MTW period.

[0237] The UE may also receive a setting of a measurement gap (MG) for L1 measurement in multiple frequencies / PCI / RSs, which is different for each of the multiple frequencies / PCI / RSs. MTW indicates the timing of measuring SSB / CSI-RS. The UE is able to send and receive data at the current frequency in MTW. During the MG, the UE adjusts the antenna in order to perform L1 measurement (detection) on a signal sent using a frequency different from the frequency used in the connected cell. Basically, the UE cannot send and receive data in the MG at the current frequency.

[0238] In the case of a UE that does not support measurement in multiple frequencies at the same time, the UE is configured with non-overlapping MTWs for RS / PCIs of different frequencies. Alternatively, the UE may also be configured with a measurement gap (MG) for intra-frequency / inter-frequency measurement.

[0239] A UE capability indicating support for simultaneous measurement of multiple frequencies (and frequency numbers) and support for the same MTW / MG for multiple frequencies may also be introduced. In the case of a UE with the above capabilities, the UE may also be configured with the same MTW / MG for multiple frequencies and / or multiple PCIs.

[0240] Fig. 22 FIG. 4 is a diagram showing an example of MTW and MG in the fifth embodiment. Fig. 22 In the example, the UE measures the SSB in the MTW of the first frequency (Freq.#1), and after a specific period, measures the SSB in the MTW of the second frequency (Freq.#2). The MTW of the first frequency is, for example, period = 40ms, offset = 0ms, and period = 5ms. The MTW of the second frequency is, for example, period = 40ms, offset = 20ms, and period = 5ms. The period of the MG of the second frequency includes the period of the MTW of the second frequency.

[0241] For SSB cells of the same / different frequencies that are not aligned, the UE may be configured with different MTW / MG for different RS / PCIs. In addition, the following options 1 to 3 may also be applied.

[0242] Option 1

[0243] The UE does not expect repetition of MTW / MG for different RS / PCIs (the MTW / MG is not repeated).

[0244] Option 2

[0245] Duplication of MTW / MG for different RS / PCIs is allowed. For example, one MTW / MG can also be a subset of other MTW / MG.

[0246] Fig.23 FIG. 2 is a diagram showing an example of Option 2 of the fifth embodiment. Fig.23 In the example, the periods of MTW (PCI#1, for Freq.#1) and MTW (PCI#2, for Freq.#1) overlap.

[0247] Option 3

[0248] A single MTW / MG with one periodicity is set for different RS / PCIs. However, multiple offsets and / or multiple periods can be set for the MTW / MG.

[0249] Fig.24 FIG. 4 is a diagram showing an example of Option 3 of the fifth embodiment. Fig.24 In this embodiment, one MTW is used in the SSB of PCI#1, Freq.#1 and the SSB of PCI#2, Freq.#1. However, the period and offset for measuring the SSB of PCI#1 are different from the period and offset for measuring the SSB of PCI#2.

[0250] In the case of unsynchronized cells of the same / different frequencies, for RSs of cells of each PCI, the UE may also be configured with a timing difference for indicating the timing intervals for RSs from different PCIs, compared with the reference PCI. Fig. 20In the example, a timing gap of PCI#3 is set to be compared with a reference PCI, namely PCI#1, and the UE determines the measurement timing of the SSB of PCI#3 based on the timing gap.

[0251] During the indicated timing gap, the UE does not expect to receive / transmit in the current serving cell / frequency. For such a case, scheduling restrictions such as the above-mentioned "Measurement requirements and scheduling restrictions related to L1 measurement" may also be applied. The UE may also not assume that it will receive PUCCH / PUSCH / SRS transmissions, PDCCH / PDSCH / CSI-RS for tracking / CQI during the indicated timing gap.

[0252] According to the present embodiment, it is possible to appropriately set the measurement timing window (MTW) ​​and the measurement gap (MG) when performing L1 measurement / reporting on a plurality of frequencies.

[0253] <Supplement>

[0304] (Wireless Communication System)

[0305] Hereinafter, a configuration of a wireless communication system according to an embodiment of the present disclosure will be described. In the wireless communication system, communication is performed using any one of the wireless communication methods according to the above-mentioned embodiments of the present disclosure or a combination thereof.

[0306] Fig.25 1 is a diagram showing an example of a schematic structure of a wireless communication system involved in one embodiment. The wireless communication system 1 (may also be simply referred to as system 1) may also be a system that implements communication using Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the fifth generation mobile communication system New Radio (5GNR), and the like.

[0307] In addition, the wireless communication system 1 can also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple radio access technologies (Radio Access Technology (RAT)). MR-DC can also include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA))) and NR (E-UTRA-NR Dual Connectivity (E-UTRA-NR Dual Connectivity (EN-DC))), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NR-E-UTRA Dual Connectivity (NE-DC))), etc.

[0308] In EN-DC, the base station (eNB) of LTE (E-UTRA) is the master node (Master Node (MN)), and the base station (gNB) of NR is the secondary node (Secondary Node (SN)). In NE-DC, the base station (gNB) of NR is the MN, and the base station (eNB) of LTE (E-UTRA) is the SN.

[0309] The wireless communication system 1 can also support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity (NR-NR Dual Connectivity (NN-DC)) where both MN and SN are NR base stations (gNB)).

[0310] The wireless communication system 1 may also include a base station 11 that forms a macro cell C1 with a relatively wide coverage, and a base station 12 (12a-12c) that is configured in the macro cell C1 and forms a small cell C2 that is narrower than the macro cell C1. The user terminal 20 may also be located in at least one cell. The configuration and number of each cell and user terminal 20 are not limited to the method shown in the figure. Hereinafter, when the base stations 11 and 12 are not distinguished, they are collectively referred to as base stations 10.

[0311] The user terminal 20 may be connected to at least one of the plurality of base stations 10. The user terminal 20 may use at least one of carrier aggregation (CA) using a plurality of component carriers (CC) and dual connectivity (DC).

[0312] Each CC may also be included in at least one of the first frequency band (Frequency Range 1 (FR1)) and the second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may also be included in FR1, and the small cell C2 may also be included in FR2. For example, FR1 may be a frequency band below 6 GHz (below 6 GHz (sub-6 GHz)), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). In addition, the frequency bands and definitions of FR1 and FR2 are not limited to these. For example, FR1 may also be equivalent to a frequency band higher than FR2.

[0313] 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).

[0314] Multiple base stations 10 may also be connected via wired (e.g., optical fiber based on Common Public Radio Interface (CPRI)), X2 interface, etc.) or wireless (e.g., NR communication). For example, when NR communication between base stations 11 and 12 is used as a backhaul, the base station 11 equivalent to the upper station may also be referred to as an Integrated Access Backhaul (IAB) donor, and the base station 12 equivalent to a relay station (relay) may also be referred to as an IAB node.

[0315] The base station 10 may also be connected to the core network 30 via other base stations 10 or directly. The core network 30 may also include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

In addition, communication with an external network (e.g., network) may also be performed via DN.

[0317] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0318] In the wireless communication system 1, a wireless access method based on orthogonal frequency division multiplexing (OFDM) may be used. For example, in at least one of the downlink (DL) and the uplink (UL), cyclic prefix OFDM (CP-OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), etc. may be used.

[0319] The radio access scheme may also be referred to as a waveform. In addition, in the wireless communication system 1, other radio access schemes (for example, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the radio access schemes for UL and DL.

[0320] As downlink channels, the wireless communication system 1 may use a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH))), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc.

[0321] In addition, as uplink channels, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20), an uplink control channel (Physical Uplink Control Channel (PUCCH))), a random access channel (Physical Random Access Channel (PRACH)) and the like can also be used in the wireless communication system 1.

[0322] User data, high-layer control information, system information block (SIB), etc. are transmitted through PDSCH. User data, high-layer control information, etc. can also be transmitted through PUSCH. In addition, master information block (MIB) can also be transmitted through PBCH.

[0325] In the detection of PDCCH, the control resource set (CORESET) and the search space can also be used. CORESET corresponds to the resources for searching DCI. The search space corresponds to the search area and search method of PDCCH candidates. A CORESET can also be associated with one or more search spaces. The UE can also monitor the CORESET associated with a search space based on the search space setting.

[0326] A search space may also correspond to a PDCCH candidate corresponding to one or more aggregation levels. One or more search spaces may also be referred to as a search space set. In addition, the "search space", "search space set", "search space setting", "search space set setting", "CORESET", "CORESET setting" and the like in the present disclosure may also be rewritten mutually.

[0327] Uplink control information (uplink control information (UCI)) including at least one of channel state information (CSI), delivery confirmation information (e.g., also known as hybrid automatic repeat request confirmation (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR) can also be transmitted through PUCCH. The random access preamble used to establish a connection with a cell can also be transmitted through PRACH.

[0328] In the present disclosure, downlink, uplink, etc. may be expressed without the word “link.” In addition, various channels may be expressed without the word “physical” at the beginning.

[0329] In the wireless communication system 1, a synchronization signal (Synchronization Signal (SS)), a downlink reference signal (Downlink Reference Signal (DL-RS)), etc. can also be transmitted. As DL-RS, in the wireless communication system 1, a cell-specific reference signal (Cell-specific Reference Signal (CRS)), a channel state information reference signal (Channel State Information Reference Signal (CSI-RS)), a demodulation reference signal (DeModulation Reference Signal (DMRS)), a positioning reference signal (Positioning Reference Signal (PRS)), a phase tracking reference signal (Phase Tracking Reference Signal (PTRS)), etc. can also be transmitted.

A signal block including SS (PSS, SSS) and PBCH (and DMRS for PBCH) may also be referred to as SS / PBCH block, SS block (SSB), etc. In addition, SS, SSB, etc. may also be referred to as reference signals.

[0331] In addition, in the wireless communication system 1, as an uplink reference signal (Uplink Reference Signal (UL-RS)), a measurement reference signal (Sounding Reference Signal (SRS)), a demodulation reference signal (DMRS), etc. can also be transmitted. In addition, DMRS can also be called a user terminal specific reference signal (UE-specific Reference Signal).

For example, a functional block (structural unit) that implements a sending function may also be referred to as a transmitting unit, a transmitter, etc. Any one of them is as described above, and the implementation method is not particularly limited.

[0381] For example, a base station, a user terminal, etc. in one embodiment of the present disclosure may also function as a computer that performs processing of the wireless communication method of the present disclosure.

The hardware structure of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the figure, or may be configured to exclude some of the devices.

[0383] For example, only one processor 1001 is shown, but there may be multiple processors. In addition, the processing may be performed by one processor, or may be performed by two or more processors simultaneously, sequentially, or in other ways. In addition, the processor 1001 may also be implemented by one or more chips.

[0384] The functions of the base station 10 and the user terminal 20 are realized, for example, by reading specific software (program) into hardware such as the processor 1001 and the memory 1002, so that the processor 1001 performs calculations and controls communication via the communication device 1004, or controls at least one of the reading and writing of data in the memory 1002 and the storage 1003.

[0393] (Variation Example)

[0394] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may also be replaced with terms having the same or similar meanings. For example, channels, code elements, and signals (signals or signaling) may also be rewritten with each other. In addition, a signal may also be a message. A reference signal may also be referred to as RS, and may also be referred to as a pilot, a pilot signal, etc. depending on the standard applied. In addition, a component carrier (CC) may also be referred to as a cell, a frequency carrier, a carrier frequency, etc.

[0395] A wireless frame may also be composed of one or more periods (frames) in the time domain. Each period (frame) of the one or more periods (frames) constituting a wireless frame may also be referred to as a subframe. Further, a subframe may also be composed of one or more time slots in the time domain. A subframe may also be a fixed time length (e.g., 1 ms) that is not dependent on a parameter set (numerology).

[0396] Here, the parameter set may also be a communication parameter applied in at least one of the transmission and reception of a certain signal or channel. For example, the parameter set may also represent at least one of a subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, a wireless frame structure, a specific filter processing performed by a transmitter and receiver in the frequency domain, a specific windowing processing performed by a transmitter and receiver in the time domain, and the like.

[0397] A time slot may also be composed of one or more symbols (Orthogonal Frequency Division Multiplexing (OFDM) symbols, Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, etc.) in the time domain. In addition, a time slot may also be a time unit based on a parameter set.

[0398] A time slot may also include multiple mini-slots. Each mini-slot may also be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may also be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as a PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may also be referred to as a PDSCH (PUSCH) mapping type B.

[0399] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols may also be referred to by their respective names. In addition, time units such as frames, subframes, time slots, mini-time slots, and symbols in the present disclosure may also be replaced with each other.

[0400] For example, a subframe may be referred to as a TTI, a plurality of consecutive subframes may be referred to as a TTI, and a time slot or a mini time slot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. In addition, the unit representing a TTI may be referred to as a time slot, a mini time slot, etc. instead of a subframe.

[0401] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station schedules each user terminal to allocate wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) in TTI units. In addition, the definition of TTI is not limited to this.

[0402] TTI may also be a transmission time unit for a data packet (transport block), a code block, a code word, etc. that has been channel-coded, and may also be a processing unit for scheduling, link adaptation, etc. In addition, when TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0403] In addition, when a time slot or a mini time slot is called TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can also be the minimum time unit of scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit of scheduling can also be controlled.

[0404] A TTI having a time length of 1 ms may also be referred to as a normal TTI (TTI in 3GPP Rel.8-12), a standard TTI, a long TTI, a normal subframe, a standard subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be referred to as a shortened TTI, a short TTI, a partial TTI (partial or fractional TTI), a shortened subframe, a short subframe, a mini time slot, a sub time slot, a time slot, etc.

[0405] In addition, a long TTI (e.g., normal TTI, subframe, etc.) can also be rewritten as a TTI with a time length exceeding 1 ms, and a short TTI (e.g., shortened TTI, etc.) can also be rewritten as a TTI with a TTI length shorter than that of the long TTI and longer than 1 ms.

[0406] 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 (subcarriers) in the frequency domain. The number of subcarriers included in an RB may also be the same regardless of the parameter set, for example, 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0407] In addition, an RB may also include one or more symbols in the time domain, and may also be the length of a slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks, respectively.

[0408] In addition, one or more RBs may also be referred to as a physical resource block (Physical RB (PRB)), a sub-carrier group (Sub-Carrier Group (SCG)), a resource element group (Resource Element Group (REG)), a PRB pair, an RB pair, etc.

[0409] In addition, a resource block may be composed of one or more resource elements (RE). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0410] Bandwidth Part (BWP) (also referred to as partial bandwidth, etc.) may also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, common RBs may also be identified by the index of the RB relative to the common reference point of the carrier. PRBs may also be defined in a BWP and numbered within the BWP.

[0411] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). For a UE, one or more BWPs may be configured in one carrier.

[0412] At least one of the set BWPs may be activated, and the UE may not assume that it will transmit or receive a specific signal / channel other than the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may also be rewritten as "BWP".

[0413] In addition, the above-mentioned structures such as radio frames, subframes, time slots, mini-time slots and symbols are only examples. For example, the number of subframes included in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, and the cyclic prefix (CP) length can be changed in various ways.

For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be mentioned throughout the above description may also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0417] Furthermore, information, signals, etc. can be output in at least one of the following directions: from a higher layer (upper layer) to a lower layer (lower layer), and from a lower layer to a higher layer. Information, signals, etc. can also be input and output via multiple network nodes.

[0418] The input and output information, signals, etc. may be stored in a specific location (e.g., a memory), or may be managed using a management table. The input and output information, signals, etc. may be overwritten, updated, or appended. The output information, signals, etc. may also be deleted. The input information, signals, etc. may also be sent to other devices.

[0419] The notification of information is not limited to the aspects / implementations described in the present disclosure, and may also be performed by other methods. For example, the notification of information in the present disclosure may also be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI))), high-layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB)), System Information Block (SIB), etc.), Medium Access Control (MAC) signaling), other signals or a combination thereof.

[0420] In addition, physical layer signaling may also be referred to as layer 1 / layer 2 (Layer 1 / Layer 2 (L1 / L2)) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. In addition, RRC signaling may also be referred to as an RRC message, such as an RRC connection establishment (RRC Connection Setup) message, an RRC connection reconstruction (RRC Connection Reconfiguration) message, etc. In addition, MAC signaling may also be notified using, for example, a MAC control element (MACControl Element (CE)).

[0421] Furthermore, notification of specific information (eg, notification of “it is X”) is not limited to explicit notification, but may be performed implicitly (eg, by not notifying the specific information or by notifying other information).

[0422] The determination can be made by a value represented by a bit (0 or 1), by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a specific value).

[0423] Whether software is called software, firmware, middle-ware, microcode, hardware description language, or other names, it should be broadly interpreted as meaning instructions, instruction sets, code, code segments, program code, program, sub-program, software modules, applications, software applications, software packages, routines, sub-routines, objects, executable files, execution threads, procedures, functions, etc.

[0424] In addition, software, instructions, information, etc. may also be sent and received via a transmission medium.

[0453] Any reference to an element using the terms "first", "second", etc. used in this disclosure does not fully define the amount or order of these elements. These terms can be used in this disclosure as a convenient method to distinguish between two or more elements. Therefore, reference to the first and second elements does not mean that only two elements can be used or that the first element must take precedence over the second element in some form.

[0454] The term "determining" used in the present disclosure may include a variety of actions. For example, "determining" may also refer to situations where judging, calculating, computing, processing, deriving, investigating, looking up (e.g., searching in a table, database or other data structure), ascertaining, etc. are considered to be "determining".

[0455] In addition, "judgment (decision)" may also be a situation where receiving (for example, receiving information), sending (for example, sending information), input (input), output (output), accessing (for example, accessing data in a memory), etc. are regarded as making a "judgment (decision)".

[0456] In addition, "judgment (decision)" can also be regarded as a situation where resolving, selecting, choosing, establishing, comparing, etc. are regarded as a situation where "judgment (decision)" is performed. That is, "judgment (decision)" can also be regarded as a situation where some actions are regarded as a situation where "judgment (decision)" is performed.

[0457] In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)" and so on.

[0458] The “maximum transmit power” recorded in the present disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0459] The terms "connected", "coupled", or all their variations used in this disclosure refer to all direct or indirect connections or combinations between two or more elements, and may include the situation where one or more intermediate elements exist between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be physical, logical, or a combination thereof. For example, "connection" may also be rewritten as "access".

[0460] In the present disclosure, when two elements are connected, it is possible to consider being "connected" or "combined" to each other using one or more wires, cables, printed electrical connections, etc., as well as using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, light (both visible and invisible) region, etc. as several non-limiting and non-inclusive examples.

[0461] In the present disclosure, the term "A is different from B" may also mean "A and B are different from each other". In addition, the term may also mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same manner as "different".

[0462] When the terms “include,” “including,” and variations thereof are used in the present disclosure, these terms have an inclusive meaning, similar to the term “comprising.” Furthermore, the term “or” used in the present disclosure does not have an exclusive OR meaning.

[0463] In the present disclosure, when an article is added by translation like a, an, and the in English, for example, the present disclosure may also include a case where the noun following the article is in plural form.

[0464] In the present disclosure, "below", "less than", "above", "more than", "equal to", etc. may be rephrased with each other. Furthermore, in the present disclosure, terms meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. are not limited to the original degree, comparative degree and superlative degree, but may be rephrased with each other. Furthermore, in the present disclosure, expressions with "ith" (i is an arbitrary integer) attached to terms meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. are not limited to the original degree, comparative degree and superlative degree, but may be rephrased with each other (for example, "highest" and "i-th highest" may be rephrased with each other).

[0465] In the present disclosure, “of,” “for,” “regarding,” “related to,” “associated with,” etc. may also be replaced by each other.

[0466] The invention involved in the present disclosure has been described in detail above, but it is obvious to those skilled in the art that the invention involved in the present disclosure is not limited to the embodiments described in the present disclosure. The invention involved in the present disclosure can be implemented as a modified and altered mode without departing from the gist and scope of the invention determined based on the description of the claims. Therefore, the description of the present disclosure is for the purpose of illustrative description and does not have any limiting meaning on the invention involved in the present disclosure.
