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 of the Third Generation Partnership Project (3GPP)).

[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.

[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 future wireless communication systems (for example, wireless communication systems after Rel.16 / 5G), it is envisaged that communications will be controlled based on inter-cell mobility including non-serving cells, or inter-cell mobility utilizing multiple transmitting and receiving points (for example, Multi-TRP (MTRP)).

[0009] In addition, in inter-cell mobility, it is also envisioned to set a serving cell and a candidate cell and perform switching from the serving cell to the candidate cell. In this case, it is also envisioned that: for the candidate cell (or the frequency of the candidate cell), CSI measurement / reporting (for example, measurement and reporting of L1-RSRP / L1-SINR) is supported.

[0010] However, when the candidate cells are set, how to control CSI measurement / reporting becomes a problem. If CSI measurement / reporting is not performed appropriately, there is a concern that the quality of communication may deteriorate.

[0011] The present disclosure has been made in view of this point, and one of its objects is to provide a terminal, a wireless communication method, and a base station that can appropriately control measurement / reporting related to a candidate cell even when the candidate cell is set.

[0012] Means for solving problems

[0013] A terminal involved in one method of the present disclosure is characterized in that it has: a receiving unit, which receives first information related to one or more candidate cells that are set, and second information related to one or more candidate cells for which L1 beam measurement and reporting are set; and a control unit, which controls L1 beam measurement and reporting of the one or more candidate cells for which L1 beam measurement and reporting are set based on the second information, and the candidate cell for which L1 beam measurement and reporting is set is included in the one or more candidate cells that are set.

[0014] Effects of the Invention

[0015] According to one aspect of the present disclosure, even when a candidate cell is set, measurement / reporting related to the candidate cell can be appropriately controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] (TCI, spatial relationship, QCL)

[0038] In NR, research is being conducted 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 coding) of at least one of a signal and a channel (expressed as signal / channel) in the UE based on the transmission configuration indication state (Transmission Configuration Indication state (TCI state)).

[0039] The TCI state may also represent the TCI state applied to the downlink signal / channel. The TCI state equivalent to the TCI state applied to the uplink signal / channel may also be expressed as a spatial relation.

[0040] The so-called TCI state is information related to Quasi-Co-Location (QCL) of signals / channels, and may also be called spatial reception parameters, spatial relationship information, etc. The TCI state may also be set for each channel or each signal to the UE.

[0041] QCL is an indicator indicating the statistical properties of a signal / channel. For example, when a certain signal / channel is in a QCL relationship with other signals / channels, it can also mean that it can be assumed that at least one of Doppler shift, Doppler spread, average delay, delay spread, and spatial parameter (e.g., spatial Rx parameter) is the same among these different signals / channels (at least one of them is QCL).

[0042] In addition, the spatial reception parameter may also correspond to the reception beam of the UE (eg, reception simulation beam), or the beam may be determined based on the spatial QCL. The QCL (or at least one element of the QCL) in the present disclosure may also be rewritten as sQCL (spatial QCL).

[0043] Regarding QCL, multiple types (QCL types) may also be specified. For example, four QCL types, namely types AD, may be set, and the parameters (or parameter sets) that can be assumed to be the same in the four QCL types AD are different, and the parameters (also referred to as QCL parameters) are expressed as follows:

[0044] QCL Type A (QCL-A): Doppler shift, Doppler spread, average delay, and delay spread,

[0045] QCL type B (QCL-B): Doppler shift and Doppler spread,

[0046] QCL Type C (QCL-C): Doppler shift and average delay,

[0047] QCL type D (QCL-D): spatial reception parameters.

[0048] The situation in which the UE assumes that a certain control resource set (CORESET), channel or reference signal is in a specific QCL (e.g., QCL type D) relationship with other CORESETs, channels or reference signals can also be called QCL assumption.

[0049] The UE may also determine at least one of the transmit beam (Tx beam) and receive beam (Rx beam) of the signal / channel based on the TCI status or QCL assumption of the signal / channel.

[0050] The TCI state may be, for example, information related to the QCL between the channel being the object (in other words, the reference signal (RS) used for the channel) and other signals (for example, other RS). The TCI state may also be set (indicated) by high-layer signaling, physical layer signaling, or a combination thereof.

[0051] In the present disclosure, the higher layer signaling may be, for example, any one of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, etc., or a combination thereof.

[0052] MAC signaling may also use, for example, MAC Control Element (MAC CE), MAC Protocol Data Unit (MAC Protocol Data Unit (PDU)), etc. Broadcast information may also be, for example, Master Information Block (MIB), System Information Block (SIB), minimum system information (Remaining Minimum System Information (RMSI)), Other System Information (Other System Information (OSI)), etc.

[0053] The physical layer signaling may be, for example, downlink control information (Downlink Control Information (DCI))).

[0054] In addition, the channel / signal that becomes the application object of the TCI state can also be called the target channel / reference signal (target channel / RS), abbreviated as target, etc., and the other signals mentioned above can also be called reference reference signal (reference RS), source RS (source RS), abbreviated as reference, etc.

[0055] The channel whose TCI state or spatial relationship is set (specified) may be, for example, at least one of the downlink shared channel (Physical Downlink Shared Channel (PDSCH)), the downlink control channel (Physical Downlink Control Channel (PDCCH)), the uplink shared channel (Physical Uplink Shared Channel (PUSCH)), and the uplink control channel (Physical Uplink Control Channel (PUCCH)).

[0056] In addition, the RS that is in a QCL relationship with the channel may be, for example, a synchronization signal block (SynchronizationSignal Block (SSB)), a channel state information reference signal (CSI-RS)), a measurement reference signal (Sounding Reference Signal (SRS)), a tracking CSI-RS (also called a tracking reference signal (TRS))), a QCL detection reference signal (also called QRS), a demodulation reference signal (DeModulation Reference Signal (DMRS)), etc., at least one of the following.

[0057] The SSB is a signal block including at least one of a primary synchronization signal (Primary Synchronization Signal (PSS)), a secondary synchronization signal (Secondary Synchronization Signal (SSS)), and a broadcast channel (Physical Broadcast Channel (PBCH)). The SSB may also be referred to as an SS / PBCH block.

[0058] The RS of QCL type X in the TCI state may also mean an RS that is in a QCL type X relationship with a certain channel / signal (DMRS), and the RS may also be referred to as a QCL source of QCL type X in the TCI state.

[0059] (Inter-cell mobility)

[0060] In NR, one or more transmission / reception points (Transmission / Reception Point (TRP)) (Multi-TRP (MTRP)) are being studied for DL ​​transmission to the UE. In addition, the UE is being studied for UL transmission to one or more TRPs.

[0061] Consider that a UE receives channels / signals from multiple cells / TRPs in inter-cell mobility (e.g., L1 / L2 inter-cell mobility) (refer to Figure 1A , B).

[0062] Figure 1AAn example of inter-cell mobility including non-serving cells (e.g., Single-TRP inter-cell mobility) is shown. The UE may also be set with one TRP (or single TRP) in each cell. Here, a situation is shown where the UE receives channels / signals from the base station / TRP of cell #1, which is a serving cell, and the base station / TRP of cell #3, which is not a serving cell (a non-serving cell). For example, this is equivalent to a situation where the UE switches / hands over from cell #1 to cell #3 (e.g., fast cell switch).

[0063] In this case, the selection of the port (e.g., antenna port) / TRP may also be performed dynamically. The selection of the port (e.g., antenna port) / TRP may also be performed based on the TCI state indicated or updated through the DCI / MAC CE. Here, it is shown that different physical cell IDs (e.g., PCIs) are supported for cell #1 and cell #3.

[0064] Figure 1B An example of a multi-TRP scenario (e.g., inter-cell mobility using multiple TRPs (Multi-TRP inter-cell mobility)) is shown. The UE may also be set with multiple (e.g., 2) TRPs (or different CORESET pool indexes) in each cell. Here, a situation is shown where the UE receives channels / signals from TRP#1 and TRP2. In addition, here, a situation is shown where TRP#1 corresponds to physical cell ID (PCI)#1 and TRP#2 corresponds to PCI#2.

[0065] Multiple TRPs (TRP#1, #2) can also be connected through an ideal / non-ideal backhaul, and information, data, etc. can be exchanged. The same or different code words (Code Word (CW)) and the same or different layers can also be sent from each TRP of the multiple TRPs. As a method of sending multiple TRPs, Figure 1B As shown, non-coherent joint transmission (NCJT) can also be used. Here, the case of performing NCJT between TPRs corresponding to different PCIs is shown. In addition, the same service cell setting can also be applied / set for TRP#1 and TRP#2.

[0066] Multiple PDSCHs (multi-PDSCHs) subjected to NCJT may 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 TRP#1 and the second PDSCH from TRP#2 may also be repeated with respect to at least one of the time and frequency resources. The first PDSCH and the second PDSCH may be used for the transmission of the same TB or for the transmission of different TBs.

[0067] It is also possible to assume that the first PDSCH and the second PDSCH are not in a quasi-co-location (QCL) relationship (not quasi-co-located). The reception of multiple PDSCHs may also be rewritten as simultaneous reception of PDSCHs of a certain QCL type (eg, QCL type D).

[0068] Multiple PDSCHs from multiple TRPs (also referred to as multiple PDSCHs) can also be scheduled using one DCI (single DCI (S-DCI), single PDCCH) (single master mode). One DCI can also be sent from one TRP of multiple TRPs. The structure of using one DCI in multiple TRPs can also be called multi-TRP (mTRP / MTRP) based on a single DCI.

[0069] Multiple PDSCHs from multiple TRPs can also be scheduled separately using multiple DCIs (multiple DCI (M-DCI), multiple PDCCH (multiplePDCCH)) (multiple master mode). Multiple DCIs can also be sent separately from multiple TRPs. The structure of using multiple DCIs in multiple TRPs can also be called multi-TRP (mTRP / MTRP) based on multiple DCIs.

[0070] The UE may also be conceived to send separate CSI reports (CSI reports) related to different TRPs. Such CSI feedback may also be referred to as separate feedback, separate CSI feedback, etc. In the present disclosure, "separate" may also be interchanged with "independent".

[0071] In inter-cell mobility, consider the following scenario 1 or scenario 2. In addition, in the present disclosure, the service cell can also be rewritten as the TRP within the service cell. Layer 1 / layer 2 (layer1 / layer2 (L1 / L2)), DCI / Medium Access Control Control Element (Medium Access Control Control Element (MAC CE)) can 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 service cell is sometimes simply recorded as "different PCI". Non-service cells, cells with different PCIs, and additional cells can also be rewritten with each other.

[0072] <Scenario 1>

[0073] Scenario 1 corresponds to, for example, inter-cell mobility of multiple TRPs. In addition, scenario 1 may also be a scenario that does not correspond to inter-cell mobility of multiple TRPs. In scenario 1, for example, the following process is performed.

[0074] (1) The UE receives from the serving cell: the configuration of the SSB for beam measurement corresponding to the TRP of the PCI different from that of the serving cell, and the configuration required for using the wireless resources for data transmission and reception, including resources of the different PCI.

[0075] (2) The UE performs beam measurement of the TRP corresponding to different PCIs and reports the beam measurement results to the serving cell.

[0076] (3) Based on the above report, the Transmission Configuration Indication (TCI) state associated with the TRP corresponding to the different PCI is activated through L1 / L2 signaling from the serving cell.

[0077] (4) The UE uses the UE-dedicated channel on the TRP corresponding to different PCIs for transmission and reception.

[0078] (5) The UE needs to always cover the serving cell, including the case of multiple TRPs. As in the previous system, the UE needs to use common channels (Broadcast Control Channel (BCCH), Paging Channel (PCH)) from the serving cell.

[0079] In scenario 1, when the UE sends or receives signals to an additional cell / TRP (TRP corresponding to the PCI of the additional cell), the serving cell (the assumption of the serving cell in the UE) does not change. In other words, switching of the serving cell based on L1 / L2 is not supported. The UE can also be set with high-layer 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.

[0080] Figure 2A This is a diagram showing an example of UE movement in Rel. 17. Assume that the UE moves from a cell (serving cell) of PCI#1 to a cell (additional cell) of PCI#3 (which overlaps with the serving cell). In this case, Rel. 17 does not support switching of serving cells based on L1 / L2.

[0081] An additional cell is a cell with an additional PCI 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 messages), the UE needs to be within the coverage of the serving cell. When the UE moves out of the coverage of the serving cell, it is necessary to switch cells through handover (also known as L3 mobility).

[0082] <Scenario 2>

[0083] In scenario 2, L1 / L2 inter-cell mobility is applied. In L1 / L2 inter-cell mobility, it is possible to change the serving cell using functions such as beam control without resetting RRC. In other words, it is possible to perform transmission and reception with the additional cell without switching (or without performing the L3 mobility process). Since a period during which data communication cannot be performed due to the need for RRC reconnection, etc. occurs for switching, data communication can be continued even when the serving cell is changed by applying L1 / L2 inter-cell mobility that does not require switching. In scenario 2, for example, the following process is performed.

[0084] (1) For beam measurement / changing the serving cell, the UE receives the SSB configuration of a cell (additional cell) having a different PCI from the serving cell.

[0085] (2) The UE performs beam measurement of cells using different PCIs and reports the measurement results to the serving cell.

[0086] (3) The UE may also receive the configuration of a cell with a different PCI (serving cell configuration) through high-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.

[0087] (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.

[0088] (5) The UE changes the serving cell (assumption of the serving cell) and starts receiving / transmitting using the pre-set UE-dedicated channel and TCI state.

[0089] 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 and later.

[0090] 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 leave the coverage of the previous serving cell.

[0091] (Setting of candidate cells)

[0092] In L1 / L2 inter-cell mobility, in addition to the service cell, a candidate cell may also be set. In the present disclosure, a candidate cell may also be rewritten as a target cell, an additional cell, or an additional PCI. Alternatively, more than one candidate cell (or candidate cell group) may be associated with each service cell, respectively, or more than one candidate cell (or candidate cell group) may be associated with multiple service cells in common.

[0093] Regarding the setting of candidate cells (or candidate cell groups), specific high-level parameters (e.g., ServingCellConfig) may also be used to set the same as the inter-cell beam management (inter-cellBM) of the existing system (e.g., before Rel.17). Alternatively, the setting of candidate cells (or candidate cell groups) may also be reused: the framework for carrier aggregation settings (e.g., CA configuration framework), or the framework for CHO (Conditional Handover) / CPC (Conditional PSCell Change) settings.

[0094] For candidate cells (or candidate cell groups) configured by higher-layer parameters, activation / deactivation instructions may be issued to the UE via MAC CE / DCI.

[0095] As the setting of the candidate cell (or the association with the serving cell), for example, at least one of the following setting examples 1 to 3 may also be applied. Here, an example of setting SpCell#0, SCell#1, and SCell#2 as the serving cell, and a candidate cell / candidate cell group that is set separately from the serving cell is shown. The following setting examples 1 to 3 are examples, and the number of serving cells / candidate cells / candidate cell groups, the association between the serving cell and the candidate cell, etc. may also be appropriately changed without being limited thereto. Alternatively, in addition to / instead of setting examples 1 to 3, other setting examples may also be supported / applied.

[0096] [Setting Example 1]

[0097] In setting example 1, for each serving cell (or the frequency domain corresponding to each serving cell), one or more candidate cells are respectively associated / set (refer to Figure 3 ). Here, it is shown that candidate cells #0-1, #0-2, and #0-3 are associated with SpCell#0 (or the frequency domain corresponding to SpCell#0), candidate cell #1-1 is associated with SCell#1 (or the frequency domain corresponding to SCell#1), and candidate cells #2-1 and #2-2 are associated with SCell#2 (or the frequency domain corresponding to SpCell#2). Information related to the association can also be set / indicated to the UE from the base station via RRC / MAC CE / DCI.

[0098] [Setting Example 2]

[0099] In setting example 2, for the MAC entity / MCG / SCG, the candidate cell is associated / set (refer to Figure 3 ). Here, the situation where candidate cells #3-#8 are associated with the MAC entity / MCG / SCG is shown. In this case, the candidate cells are not associated with each serving cell, and the candidate cells are set for the MAC entity or cell group (for example, MCG / SCG). Information related to the candidate cells set for each cell can also be set / indicated to the UE from the base station via RRC / MAC CE / DCI.

[0100] [Setting Example 3]

[0101] In setting example 3, one or more candidate cell groups are set (refer to Figure 3). The candidate cell group has more than one candidate cell. Here, it is shown that a candidate cell group #1 having candidate cells #0-#2, a candidate cell group #2 having candidate cells #0 and #1, and a candidate cell group #3 having candidate cell #0 are set. At least one of the information related to the set candidate cell group and the information related to the candidate cells included in each candidate cell group can also be set / indicated to the UE from the base station via RRC / MAC CE / DCI.

[0102] [Serving cell switching]

[0103] In the existing system (eg, Rel. 17), an L1 beam indication related to the TCI status of an additional PCI (or an additional cell) is supported (eg, an indication based on the TCI status field of the DCI).

[0104] After Rel.18, it is envisaged to support: a new L1 / L2 signal (e.g., DCI / MAC CE) for indicating the switching of serving cells (e.g., serving cells switch). As the indication, it is also envisaged to support at least one of an implicit indication and an explicit indication. An implicit indication may, for example, mean that a certain CORESET is updated to a TCI state associated with an additional PCI through a MAC CE. An explicit indication may also mean directly indicating the switching of a cell through a DCI / MAC CE.

[0105] For example, in the example 1 of the candidate cell setting, a specific candidate cell may be designated as a serving cell (or instructed to switch to a serving cell) via L1 / L2 signaling. Figure 4A In the figure, it is shown that: through L1 / L2 signaling, candidate cell #0-2 becomes the SpCell of MCG / SCG (SpCell#0 and candidate cell #0-2 are switched). In addition, it is shown that: through L1 / L2 signaling, candidate cell #2-1 becomes the SCell of MCG / SCG (SCell#2 and candidate cell #2-1 are switched).

[0106] Alternatively, in the example 2 of setting the candidate cell, a specific candidate cell may be designated as a serving cell (or instructed to switch to a serving cell) via L1 / L2 signaling. Figure 4B , it is shown that: through L1 / L2 signaling, the candidate cell #4 becomes the SpCell of the MCG / SCG (SpCell #0 and the candidate cell #4 are switched).

[0107] Alternatively, in the candidate cell setting example 3, a specific candidate cell group (or one or more candidate cells included in the specific candidate cell group) may be changed / updated to a serving cell group via L1 / L2 signaling. Figure 4C , a situation is shown in which, through L1 / L2 signaling, candidate cell group #1 (or candidate cells #0-#2 included in candidate cell group #1) becomes a service cell group (the service cell group and candidate cell group #1 are switched). Among the candidate cells included in candidate cell group #1 (here, candidate cells #0-#2), a candidate cell associated with SpCell #0 or a candidate cell set to the same frequency domain as SpCell #0 (here, candidate cell #0) can also be set as a new SpCell. Alternatively, a candidate cell that becomes a SpCell can also be indicated through L1 / L2 signaling.

[0108] (CSI report settings)

[0109] Figure 5 This is a diagram showing an overview of the CSI reporting configuration of RRC. Figure 5 The CSI report setting of RRC in 3GPP Rel.17 is shown. Figure 5 As shown, the CSI report configuration (CSI-ReportConfig) includes "resourcesForChannelMeasurement", "csi-IM-resourcesForInterference", "nzp-CSI-RS-resourcesForInterference", "Report quantity", etc. "resourcesForChannelMeasurement", "csi-IM-resourcesForInterference", and "nzp-CSI-RS-resourcesForInterference" correspond to the CSI resource configuration "CSI-ResourceConfig".

[0110] Figure 6 FIG. 1 is a diagram showing a portion of the CSI resource configuration of Rel.17. Figure 6 As shown, in the CSI resource configuration (CSI-ResourceConfig), "csi-SSB-ResourceSetList" is included. "csi-SSB-ResourceSetList" is a reference target list of SSB resources used in CSI measurement and reporting in the CSI-RS resource set. When the number of report groups (nrofReportedGroups-r17) is set in the CSI report configuration, "csi-SSB-ResourceSetListExt-r17" is used to add elements to "csi-SSB-ResourceSetList".

[0111] Figure 7 FIG. 1 is a diagram showing a portion of a CSI-SSB resource set of Rel.17. Figure 7 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 entries as the csi-SSB-ResourceList. The first entry in the list indicates the value of the PCI corresponding to the first entry of the csi-SSB-ResourceList, the second entry in the list indicates the value of the PCI corresponding to the second entry of the csi-SSB-ResourceList, and the same is true for the following entries.

[0112] 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 configuration (ServingCellConfig), and the PCI is additionalPCI-r17 of the SSB-MTC-AdditionalPCI-r17.

[0113] Figure 8 This is a diagram showing the settings related to L3 measurement / reporting of Rel.17. associatedMeasGapSSB-r17 indicates the associated measurement gap for SSB measurement of the measurement object identified by ssb-ConfigMobility. When multiple MeasObjectNRs with the same SSB frequency are set, the network sets the same measurement gap ID in this field for each MeasObjectNR. In the absence of this field, the associated measurement gap is a gap set via gapFR1, gapFR2, or gapUE.

[0114] associatedMeasGapCSIRS-r17 indicates the associated measurement gap for CSI-RS measurement identified by csi-rs-ResourceConfigMobility of the measurement object. In the absence of this field, the associated measurement gap is a gap set via gapFR1, gapFR2, or gapUE.

[0115] <Enhancement of L1 measurement reports for L1 / L2 inter-cell mobility>

[0116] When the RS (mainly SSB) of the serving cell and the non-serving cell are set in the same CSI reporting setting (or the same CSI resource setting), in addition to the previous reporting content, the UE may also additionally report several indicators representing the serving / non-serving cells.

[0117] When the new RRC parameters are set, in addition to the SSB index / CRI and L1-RSRP (Reference Signal Received Power) / L1-SINR (Signal to Interference plus Noise Ratio) values, the UE can also report the L3-RSRP value (per beam / per cell / per multiple beams).

[0118] <Event-triggered L1 beam reporting for L1 / L2 inter-cell mobility>

[0119] It is also possible to reuse one or more existing events used for RRM in TS38.331 to trigger non-periodic L1 beam reporting. In order to trigger non-periodic L1 beam reporting, one or more new / separate events may also be defined. It is also possible to use any combination of two or more events as a triggered L1 beam report. 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 of the measurement results of RSRP (L1-RSRP / L3-RSRP), RSRQ, and SINR (RS-SINR).

[0120] Event A2: The measurement result of the serving cell is worse than the threshold.

[0121] Event A3: The measurement result of the neighboring cell (the value obtained by adding the offset to the measurement result) is better than the measurement result of the SpCell (the value obtained by adding the offset to the measurement result).

[0122] Event A4: The measurement result of the neighboring cell (a value obtained by adding an offset to the measurement result) is better than a threshold.

[0123] Event A5: The measurement result of the SpCell is worse than the first threshold, and the measurement result of the neighboring cell (a value obtained by adding an offset to the measurement result) is better than the second threshold.

[0124] Event A6: The measurement result of the neighboring cell (a value obtained by adding an offset to the measurement result) is better than the measurement result of the serving cell (Secondary Cell (SCell)) (a value obtained by adding an offset to the measurement result).

[0125] Event I1: The interference measurement result is higher than the threshold.

[0126] Thus, it is assumed that, in L1 / L2 inter-cell mobility (for example, switching / conversion from a serving cell to a candidate cell (or an additional cell / target cell)), when the candidate cell is set / applied / supported, L1 beam measurement / report (or CSI measurement / report) of the candidate cell / serving cell is performed. However, in this case, how to control the setting / operation of the L1 beam measurement / report (or CSI measurement / report) has not been fully studied. In the case where the L1 beam measurement / report (or CSI measurement / report) of the candidate cell / serving cell is not properly performed, there is a concern that the communication quality may deteriorate.

[0127] The inventors of the present invention focused on inter-cell mobility (e.g., cell switching) when a candidate cell (or additional cell, target cell) is set / supported, conducted research on L1 beam measurement / reporting (or CSI measurement / reporting) of the candidate cell / serving cell, and came up with the present embodiment.

[0140] (Wireless Communication Method)

[0141] <First embodiment>

[0142] In the first embodiment, an example of CSI resource configuration (CSI-ResourceConfig) / CSI report configuration (CSI-ReportConfig) in the case of supporting L1 beam measurement / reporting (eg, L1 beam measurement / reporting) of a cell of one or more frequencies is described.

[0143] In the present disclosure, L1 beam measurement / report may also be rewritten as CSI measurement / report. In addition, in the present disclosure, L1 beam measurement / report (or, CSI measurement / report) may also be rewritten as L1 beam measurement (or CSI measurement), L1 beam report (or CSI report), or both L1 beam measurement and report (or CSI measurement and report). In the present disclosure, regarding a cell, it may be applied only to a candidate cell, only to a serving cell, or to both a candidate cell and a serving cell.

[0144] In the present disclosure, the cell may also be rewritten as PCI. For example, in the L1 beam report, at least one of L1-RSRP / L1-SINR associated with one or more PCIs (e.g., serving cell PCI / supplementary PCI), L1-RSRP / L1-SINR associated with one or more frequencies (e.g., serving cell frequency / different frequencies), and L1-RSRP / L1-SINR associated with one or more CCs may also be included.

[0145] In inter-cell mobility, the switching of SpCell / SCell to candidate cells (or additional cells, target cells) of any frequency is supported, so L1 beam measurement (inter-frequency measurement) of multiple frequencies can also be supported. In the L1 beam measurement / report (or CSI measurement / report) for multiple frequencies (or frequency domains), at least one of 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 can also be included.

[0146] The UE may also receive information related to the CSI resource settings / CSI report settings of one or more candidate cells corresponding to different frequencies, and based on the information, perform a CSI report / beam report including at least one of the L1-RSRP and L1-SINR of each candidate cell.

[0147] For example, for a certain cell (e.g., a candidate cell) or a certain frequency (e.g., a frequency corresponding to a candidate cell), the UE may also perform a CSI report including one of L1-RSRP and L1-SINR, or both L1-RSRP and L1-SINR (see Fig. 9 ). Fig. 9 An example of a case where a certain CSI report (for example, CSI report #n) includes both L1-RSRP and L1-SINR.

[0148] exist Fig. 9 In the CSI report, the CSI report includes the absolute value of the maximum L1-RSRP (L1-RSRP#1) and the difference 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 from the absolute value (Differential RSRP#1,#2,#4). In addition, the CSI report may also include a field indicating the maximum L1-SINR (here, the beginning (row 1)). Here, a case is shown where L1-SINR#3 (or beam#3) is indicated as the beam with the maximum L1-SINR. In the present disclosure, the beam may also be rewritten as a resource index for a reference signal (e.g., CRI (CSI-RS Resource Indicator) / SSBRI (SS / PBCH Block Resource Indicator).

[0149] The beam selection rule (or the selection rule of the CSI to be reported) may be predefined in the specification or may be set through RRC signaling. The beam selection (or the selection of the CSI to be reported) may also be performed based on both L1-RSRP and L1-SINR.

[0150] When measuring RS in multiple frequencies and selecting the beam to be reported, the UE may first compare the L1-RSRP of cells of each frequency (or the L1-RSRP of the same frequency), and then compare the L1-SINR of cells of different frequencies (L1-SINR of cells cross frequencies). Alternatively, the UE may first compare the L1-SINR of cells of different frequencies, and then compare the L1-RSRP of the same frequency.

[0151] The UE may also perform beam selection (or selection of CSI to be reported) based on a specific high-layer parameter. The specific high-layer parameter may also be, for example, a report quantity (e.g., reportQuantity) included in a CSI report configuration (e.g., CSI-ReportConfig). On the other hand, when either L1-RSRP or L1-SINR is configured by a specific high-layer parameter, the UE may also control the configuration so that the configured one is included in the CSI report and the other is not included in the CSI report.

[0152] For example, the UE may determine beam selection (or CSI to be reported) based on at least one of the following options 1-1 to 1-3.

[0153] [Option 1-1]

[0154] The settings of both L1-RSRP and L1-SINR may also be supported through specific higher layer parameters (eg, reportQuantity) so that both L1-RSRP and L1-SINR can be reported for a beam index (or, CSI index).

[0155] For example, when both L1-RSRP and L1-SINR are configured by a specific higher layer parameter, the UE reports CSI including L1-RSRP and L1-SINR.

[0156] Alternatively, even when both L1-RSRP and L1-SINR are set, the amount of CSI reporting may be reduced (or some CSI reporting may not be performed) if certain conditions are met. The overhead of CSI reporting may also be reduced based on at least one of the following options 1-1A and 1-1B.

[0157] 《Option 1-1A》

[0158] The UE may also determine the report content (or the measurement result included in the CSI) based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR. For example, the UE may also determine whether to report both L1-RSRP and L1-SINR (or whether to report one) based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR. In the case of reporting only one of L1-RSRP and L1-SINR, the UE may also determine which measurement result to report based on the measurement result of L1-RSRP and the measurement result of L1-SINR.

[0159] Alternatively, the UE may always include the measurement result of one party (e.g., L1-RSRP) in the CSI, and determine whether to report the measurement result of the other party (e.g., L1-SINR) based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR.

[0160] The UE may also indicate the measurement result to be reported. For example, when reporting only one of L1-RSRP and L1-SINR, the UE may indicate which measurement result to report. For example, the measurement result to be reported may be indicated by using a specific field included in the CSI.

[0161] 《Option 1-1B》

[0162] The UE may also report both L1-RSRP and L1-SINR for a specific beam / cell, and report only one of L1-RSRP and L1-SINR for other beams / cells (or remaining beams / cells). In the present disclosure, a specific beam / cell may also be the best beam / cell, the beam / cell with the highest quality, the beam / cell with the highest L1-RSRS, or the beam / cell with the highest L1-SINR. A beam may also be a resource index (e.g., CRI / SSBRI) for a reference signal.

[0163] In Option 1-1A / Option 1-1B, when selecting (or reporting) both / only one of L1-RSRP and L1-SINR, the report content may be determined autonomously by the UE, or the report content may be determined based on a specific rule. For example, a specific rule is a rule for reporting measurement results that exceed a threshold value set / defined for L1-RSRP and a threshold value set / defined for L1-SINR. The threshold value of L1-RSRP / the threshold value of L1-SINR may also be set separately by higher layer signaling.

[0164] In this way, even when reporting of both L1-RSRP and L1-SINR is configured / defined, it is possible to suppress an increase in CSI reporting overhead by allowing / supporting reporting of only one based on specific conditions.

[0165] [Option 1-2]

[0166] It is also possible to support setting / indication of only one of L1-RSRP and L1-SINR through a specific higher layer parameter (eg, reportQuantity) / DCI. The UE controls to report the set / indicated measurement result (one of L1-RSRP and L1-SINR).

[0167] [Options 1-3]

[0168] The setting / indication of only one of L1-RSRP and L1-SINR may also be supported through a specific high-level parameter (e.g., reportQuantity) / DCI. The UE may also report both L1-RSRP and L1-SINR for a specific beam / cell, and report the measurement results (only one of L1-RSRP and L1-SINR) set / indicated by the high-level parameter / DCI for other beams / cells (or the remaining beams / cells).

[0169] The specific cell can be determined autonomously by the UE or set by a high-level parameter. Alternatively, if the measurement result of a CSI report (L1-RSRP or L1-SINR) not set by the high-level configuration exceeds a pre-defined / set threshold, the unset CSI report can also be performed.

[0170] In this way, even when reporting of only one of L1-RSRP and L1-SINR is configured / defined, by allowing / supporting reporting of both L1-RSRP and L1-SINR for a specific cell, detailed CSI reporting can be performed for a specific beam / cell.

[0171] [UE capabilities]

[0172] In the case of supporting L1 beam (or CSI) measurement / reporting of cells of multiple frequencies through CSI resource configuration (CSI-ResourceConfig) / CSI report configuration (CSI-ReportConfig), UE capabilities related to the number of cells configured / reported (or the number of beams, the number of CSIs) may also be imported. For example, UE capabilities related to the number of cells (or the number of beams, the number of CSIs) configured / reported for each CSI resource configuration / each CSI report configuration / each frequency may also be supported. Alternatively, UE capabilities related to the number of cells (or the number of beams, the number of CSIs) configured / reported across CSI resource configuration / CSI report configuration / frequency may also be supported.

[0173] <Second embodiment>

[0174] In the second embodiment, another example of CSI resource configuration (CSI-ResourceConfig) / CSI report configuration (CSI-ReportConfig) in the case of L1 beam measurement / reporting (e.g., L1 beam measurement / reporting) of a cell supporting one or more frequencies is described. The second embodiment can also be applied in combination with the first embodiment.

[0175] In the case where L1 beam measurement / reporting of a cell of a certain frequency is supported by CSI resource configuration (CSI-ResourceConfig) / CSI report configuration (CSI-ReportConfig), the CSI resource configuration / CSI report configuration may also include frequency-related information (e.g., frequency configuration). L1 beam measurement / reporting may also be rewritten as CSI measurement / reporting.

[0176] The frequency setting can also be a frequency setting (for example, Absolute radio-frequency channel number (ARFCN)-ValueNR) corresponding to a reference signal for measurement (for example, SSB / CSI-RS). ARFCN-ValueNR is used to indicate the ARFCN applied in the NR global frequency grid for downlink, uplink or bidirectional (TDD). Each CSI report setting / CSI resource setting corresponds to one 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.

[0177] A frequency configuration (e.g., frequency configuration) indicating the frequency of CSI measurement / reporting and a report quantity (e.g., reportQuantity) indicating the content of CSI measurement / reporting (e.g., L1-RSRP, L1-SINR) may also be configured for the UE. The configuration shown in the first embodiment may also be applied to the configuration / report of the report quantity.

[0178] For example, a frequency setting (e.g., frequency configuration) and a report amount (e.g., reportQuantity) may be included in one CSI report setting (or each CSI report setting). The following structure may also be supported: the measurement / report of both L1-RSRP and L1-SINR is set for a certain cell (or frequency), and the measurement / report of only one of L1-RSRP and L1-SINR is set for other cells (or frequencies). The UE controls CSI measurement / CSI reporting based on the frequency setting (e.g., frequency configuration) and the report amount (e.g., reportQuantity).

[0179] For example, the UE may determine beam selection (or CSI to be reported) based on at least one of the following options 2-1 to 2-3.

[0180] [Option 2-1]

[0181] The settings of both L1-RSRP and L1-SINR can also be supported through specific high-level parameters (e.g., reportQuantity) so that both L1-RSRP and L1-SINR can be reported for the beam index (or CSI index) of a certain cell (or a certain frequency).

[0182] For example, when both L1-RSRP and L1-SINR are configured for a certain cell or frequency through specific high-level parameters (e.g., frequency configuration and reporting quantity (e.g., reportQuantity)), the UE reports CSI including L1-RSRP and L1-SINR corresponding to the frequency.

[0183] Alternatively, when a specific condition is met, the amount of CSI reporting may be reduced (or certain CSI reporting may not be performed). The overhead of CSI reporting may also be reduced based on at least one of the following options 2-1A and 2-1B.

[0184] Option 2-1A

[0185] The UE may also determine the report content (or the measurement result included in the CSI) based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR. For example, the UE may also determine whether to report both L1-RSRP and L1-SINR based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR. In the case of reporting only one of L1-RSRP and L1-SINR, the UE may also determine which measurement result to report based on the measurement result of L1-RSRP and the measurement result of L1-SINR.

[0186] Alternatively, the UE may always include the measurement result of one (e.g., L1-RSRP) in the CSI, and determine whether to report the measurement result of the other (e.g., L1-SINR) based on at least one of the measurement result of L1-RSRP and the measurement result of L1-SINR.

[0187] The UE may also indicate the measurement result to be reported. For example, when reporting only one of L1-RSRP and L1-SINR, the UE may also indicate which measurement result to report. For example, the measurement result to be reported may also be indicated by using a specific field included in the CSI.

[0188] Option 2-1B

[0189] The UE may also report both L1-RSRP and L1-SINR for a specific beam / cell, and report only one of L1-RSRP and L1-SINR for other beams / cells (or remaining beams / cells). In the present disclosure, a specific beam / cell may also be the best beam / cell, the beam / cell with the highest quality, the beam / cell with the highest L1-RSRS, or the beam / cell with the highest L1-SINR.

[0190] In Option 2-1A / Option 2-1B, when selecting (or reporting) both / only one of L1-RSRP and L1-SINR, the report content may be determined autonomously by the UE or may be determined based on a specific rule. For example, a specific rule is a rule that reports measurement results that exceed a threshold set / defined for L1-RSRP and a threshold set / defined for L1-SINR. The threshold of L1-RSRP / the threshold of L1-SINR may also be set separately by higher layer signaling.

[0191] In this way, even when reporting of both L1-RSRP and L1-SINR is set / defined, it is possible to suppress an increase in CSI reporting overhead by allowing / supporting reporting of only one based on specific conditions.

[0192] [Option 2-2]

[0193] Through specific high-level parameters (e.g., frequency configuration and report quantity) / DCI, it is also possible to support the setting / indication of only one of L1-RSRP and L1-SINR for a certain cell or frequency. The UE can also control to report the measurement result (one of L1-RSRP and L1-SINR) that is set / indicated.

[0194] [Option 2-3]

[0195] Through specific high-level parameters (e.g., frequency configuration and report quantity) / DCI, the setting / indication of only one of L1-RSRP and L1-SINR may also be supported for a certain cell or frequency. The UE may also report both L1-RSRP and L1-SINR for a specific beam / cell / frequency, and report the measurement results (only one of L1-RSRP and L1-SINR) set / indicated by high-level parameters / DCI for other beams / cells / frequencies (or the remaining beams / cells / frequencies).

[0196] The specific cell can be determined autonomously by the UE or set by a high-level parameter. Alternatively, if the measurement result of a CSI report (L1-RSRP or L1-SINR) not set by a high-level parameter exceeds a predefined / set threshold, the CSI report not set can also be performed.

[0197] In this way, even when reporting of only one of L1-RSRP and L1-SINR is configured / defined, by allowing / supporting reporting of both L1-RSRP and L1-SINR for a specific cell, detailed CSI reporting can be performed for a specific beam / cell.

[0198] [UE capabilities]

[0199] In the case of supporting L1 beam (or CSI) measurement / reporting in cells of multiple frequencies through CSI resource configuration (CSI-ResourceConfig) / CSI report configuration (CSI-ReportConfig), UE capabilities related to the number of cells configured / reported (or the number of beams, the number of CSIs) may also be imported. For example, UE capabilities related to the number of cells configured / reported (or the number of beams, the number of CSIs) for each CSI resource configuration / each CSI report configuration / each frequency may also be supported. Alternatively, UE capabilities related to the number of cells configured / reported (or the number of beams, the number of CSIs) across CSI resource configuration / CSI report configuration / frequency may also be supported.

[0200] <Third Embodiment>

[0201] In the third embodiment, an example of the relationship between candidate cells configured by higher layer parameters and candidate cells or parameters configured / activated by other higher layer parameters or MAC CE will be described.

[0202] For L1 / L2 inter-cell mobility (e.g., L1 / L2 inter-cell mobility), candidate cell settings (e.g., candidate cell's configurations) are set through RRC (e.g., a first RRC parameter). Here, the candidate cells set by the first RRC parameter are also referred to as candidate cell set #A (e.g., candidate cell set A). The candidate cell set #A may include both serving cells and candidate cells, or may only include candidate cells (candidate cells corresponding to one or more serving cells). In the present disclosure, the candidate cell set may also be rewritten as a set, a cell set, a list, a cell list, a candidate cell list, or a combination of cells.

[0203] Fig.10 An example of the correspondence between the serving cell and the candidate cell is shown. Here, it is shown that SpCell#0, candidate cells #0-1, #0-2, and #0-3 are set for the first frequency, SCell#1 and candidate cell #1-1 are set for the second frequency, and SCell#2, candidate cells #2-1 and #2-2 are set for the third frequency through the first RRC (or the first RRC parameter / information element). As the first RRC parameter, one or more RRC parameters / information elements can also be indicated to the UE. For example, the first RRC parameter can also be notified for each serving cell / each frequency.

[0204] For candidate cells and serving cells, L1 beam measurement / report (or CSI measurement / report) is set through RRC (for example, a second RRC parameter). Here, the candidate cells set by the second RRC parameter are referred to as candidate cell set #B (for example, candidate cell set B (Candidate cells set B)). The base station can also control the sending of L1 / L2 cell switching indication signaling (for example, DCI / MAC CE) for indicating cell switching based on the L1 beam report (or CSI report) from the UE. In this case, it can also be set to the following structure, that is, L1 / L2 inter-cell mobility (for example, switching from a serving cell to a candidate cell) is performed within the range of candidate cell set #B (or a candidate cell of the switching destination is selected from the candidate cells included in candidate cell set #B).

[0205] Through MAC CE, the TCI state associated with the serving cell PCI / candidate cell PCI (candidate cell PCI with the same / different frequency as the serving cell PCI) is activated. Here, the candidate cells activated through MAC CE are referred to as candidate cell set #C (e.g., candidate cell set C).

[0206] In addition, when only intra-frequency mobility is supported (or inter-frequency mobility is not applied), the serving cell / candidate cell corresponding to the same frequency may also be included in the same candidate cell set. For example, SpCell #0, candidate cells #0-0, and #0-2 may also be included in the same candidate cell set (e.g., candidate cell set #E).

[0207] In this way, when the candidate cell (for example, candidate cell set #A) is set for L1 / L2 inter-cell mobility, it is necessary to properly control the relationship between the cell set for the L1 / L2 inter-cell mobility (for example, candidate cell set #A) and the candidate cell set for L1 beam measurement / reporting (for example, candidate cell set #B).

[0208] Alternatively, it is necessary to properly control the relationship between cells set for L1 / L2 inter-cell mobility (e.g., candidate cell set #A) or candidate cells set for L1 beam measurement / reporting (e.g., candidate cell set #B) and candidate cells associated with the TCI state activated by MACCE (e.g., candidate cell set #C).

[0209] The relationship between candidate cell set #A (hereinafter also referred to as set #A) / candidate cell set #B (hereinafter also referred to as set #B) / candidate cell set #C (hereinafter also referred to as set #C) can also be defined / set based on at least one of options 3-1 to 3-4.

[0210] [Option 3-1]

[0211] Any cell in set #A is set to set #B. That is, the cell (candidate cell / serving cell) set in set #B can also be selected from the cells (candidate cell / serving cell) included in set #A (set #B∈set #A).

[0212] Fig.11 An example of cells included in set #A and cells included in set #B is shown. Here, a case where set #A includes SpCell #0, candidate cells #0-1, #0-2, #0-3, SCell #1, candidate cell #1-1, SCell #2, candidate cells #2-1, and #2-2 is shown. In addition, a case where set #B includes SpCell #0, candidate cells #0-1, #0-2, #0-3, SCell #1, candidate cell #1-1, SCell #2, candidate cells #2-1, and #2-2 is shown. In addition, in set #A / set #B, a structure that only includes candidate cells (or does not include serving cells) may also be used.

[0213] Set #A (or candidate cells included in set #A) may also be configured by higher-layer parameters related to candidate cell configuration (e.g., candidate cell configuration). Set #B (or candidate cells included in set #B) may also be configured by higher-layer parameters related to L1 beam measurement / reporting or CSI measurement / reporting (e.g., L1 beam measurement / reporting, CSI-ReportConfig).

[0214] In this case, L1 / L2 inter-cell mobility (e.g., switching from a serving cell to a candidate cell) can also be performed within the range of set #B. The UE can also assume that, when a cell switching is indicated by a DCI / MAC CE, a candidate cell of the switching destination is selected from the candidate cells included in set #B.

[0215] Alternatively, it is also possible to set a structure in which any cell of set #B is set to set #A. That is, the cell (candidate cell / service cell) set to set #A can also be selected from the cells (candidate cell / service cell) included in set #B (set #A∈set #B). In this case, the channel status of other cells (for example, non-service cells) other than the candidate cells to which L1 / L2 inter-cell mobility is applied (for example, candidate cells that become switching destination candidates) can also be grasped. Based on the results of the channel status of other cells, the candidate cells to which L1 / L2 inter-cell mobility is applied can be properly re-set.

[0216] [Option 3-2]

[0217] Import a MAC CE that indicates / controls the activation / deactivation of a candidate cell. When a candidate cell included in set #A is activated / deactivated by this MAC CE, it may also be applied / set in set #B, or it may not be applied / set in set #B. In the present disclosure, deactivation may also be rewritten as disabling or dormancy.

[0218] For example, when the candidate cells included in set #A are deactivated, at least one of the following options 3-2A to 3-2D may be applied.

[0219] Option 3-2A

[0220] When a candidate cell included in set #A is deactivated, the deactivated candidate cell may be set to set #B (or the setting in set #B may also be supported). That is, even when a candidate cell is deactivated as a candidate cell for L1 / L2 inter-cell mobility, L1 beam measurement / report (or CSI measurement / report) may be set for the deactivated candidate cell.

[0221] Option 3-2B

[0222] When a candidate cell included in set #A is deactivated, the deactivated candidate cell is not set to set #B (or does not support the setting in set #B). That is, it is also possible to set the structure as follows, that is, when a candidate cell is deactivated as a candidate cell for L1 / L2 inter-cell mobility, L1 beam measurement / report (or CSI measurement / report) is not set for the deactivated candidate cell.

[0223] Option 3-2C

[0224] In the case where a candidate cell included in set #A is deactivated, the UE may also ignore L1 beam measurement / report (or CSI measurement / report) for the deactivated candidate cell. Alternatively, the UE may not be requested to perform L1 beam measurement / report (or CSI measurement / report) for the deactivated candidate cell.

[0225] For example, when the candidate cell included in set #A is deactivated and the high-level parameters related to L1 beam measurement / report (or CSI measurement / report) are set for the deactivated candidate cell, the UE may also ignore (or not be requested) the measurement / report of the candidate cell. In addition, when the candidate cell included in set #A is activated and the high-level parameters related to L1 beam measurement / report (or CSI measurement / report) are set for the activated candidate cell (for example, when activated after deactivation), the UE may also restart the measurement / report of the activated candidate cell based on the conditions set by the high-level parameters.

[0226] Option 3-2D

[0227] In the case where the candidate cell included in the set #A is deactivated, for the deactivated candidate cell (e.g., the candidate cell configured by L1 beam measurement / reporting), the UE may also ignore the L1 measurement operation including the CSI report configuration (e.g., CSI-ReportConfig) of the candidate cell. Alternatively, the UE may not be requested to perform the L1 measurement operation including the CSI report configuration (e.g., CSI-ReportConfig) of the candidate cell for the deactivated candidate cell.

[0228] "change"

[0229] At least one of options 3-2A to 3-2D may also be applied to the serving cell. For example, for a deactivated serving cell or an original serving cell after switching (eg, the original serving cell), the UE may also ignore L1 measurement / report (or may not be requested to perform L1 measurement / report).

[0230] 《UE Capabilities》

[0231] The UE capability indicating support for MAC CE (eg, new MAC CE) indicating activation / deactivation of candidate cells may also be imported. The UE capability indicating whether L1 beam measurement / reporting of deactivated serving cells / candidate cells is supported may also be imported.

[0232] [Option 3-3]

[0233] It may also support: a cell or a cell set in which cell switching is applied / supported. Here, the set of cells in which cell switching is applied / supported is referred to as set #M (or candidate cell set #M). Set #M may be set by a high-level parameter or may be obtained / selected from a specific cell set. Set #M may include only candidate cells in which cell switching is applicable or may include serving cells and candidate cells in which cell switching is applicable.

[0234] The base station may indicate the candidate cells included in the set #M to the UE as candidate cells of the handover destination. The UE may also assume that, in L1 / L2 inter-cell mobility, the candidate cells of the handover destination are indicated from the set #M.

[0235] Any cell in set #M can also be obtained / selected from set #B. That is, the cell (candidate cell / serving cell) set to set #M can also be selected from the cells (candidate cell / serving cell) included in set #B (set #M∈set #B). Thus, only the candidate cells for which L1 beam measurement / report (or CSI measurement / report) are set are set as candidate cells for cell switching.

[0236] Fig.12 An example of cells included in set #A, cells included in set #B, and cells included in set #M is shown. Here, a case where set #A includes SpCell #0, candidate cells #0-1, #0-2, #0-3, SCell #1, candidate cell #1-1, SCell #2, candidate cells #2-1, and #2-2 is shown. In addition, a case where set #B includes SpCell #0, candidate cells #0-1, #0-2, SCell #1, candidate cell #1-1, SCell #2, candidate cells #2-1, and #2-2 is shown. A case where set #M includes SpCell #0, candidate cells #0-1, #0-2, SCell #1, candidate cell #1-1, SCell #2, and candidate cell #2-1 is shown. In addition, the following structure may be possible: in set #A / set #B / set #M, only candidate cells are included (or serving cells are not included).

[0237] Alternatively, any cell of set #B may be obtained / selected from set #M. That is, the cell (candidate cell / serving cell) set to set #B may be selected from cells (candidate cell / serving cell) included in set #M (set #B∈set #M).

[0238] [Option 3-4]

[0239] Any cell of set #B is set to set #C. That is, the cell (candidate cell / serving cell) set to set #C may be selected from cells (candidate cell / serving cell) included in set #B (set #C∈set #B).

[0240] Set #C (or, candidate cells included in set #C) may also be a set (or, candidate cells) having a TCI state activated by MAC CE.

[0241] Option 3-4A

[0242] The cell indicated by the L1 / L2 signaling (e.g., DCI / MAC CE) used for cell switching may be associated with the activated TCI state or not. In other words, the cell indicated by the L1 / L2 signaling used for cell switching may be selected regardless of the setting of the activated TCI state.

[0243] Option 3-4B

[0244] Alternatively, the cells indicated by L1 / L2 signaling (eg, DCI / MAC CE) used for cell switching may be limited to cells associated with the activated TCI state.

[0245] Option 3-4 shows the relationship between set #C and set #B, but is not limited to this. It can also be applied to the relationship with other sets (for example, set #C and set #M). In this case, set #B can also be replaced with set #M and applied.

[0246] <Fourth embodiment>

[0247] In the fourth embodiment, an example of the relationship between a serving cell (or a set including serving cells) for which L1 beam measurement / reporting is set and a candidate cell (or a set including candidate cells) for which L1 beam measurement / reporting is set is described. The fourth embodiment may also be applied in combination with the first embodiment, the second embodiment, or the third embodiment.

[0248] The L1 beam measurement / report (or CSI measurement / report) of the cells in set #D is configured by higher layer parameters. Set #D may also be rewritten as a BWP / CC for which L1 beam measurement / report is configured by higher layer parameters.

[0249] In addition, L1 beam measurement / reporting may be set for a candidate cell / serving cell through a high-layer parameter. A set including the candidate cell / serving cell is included in set #B (or candidate cell set #B). Based on the L1 beam report, L1 / L2 cell switching indication signaling indicating cell switching may also be indicated to the UE.

[0250] [Option 4-1]

[0251] The cells of set #D may also be associated only with the serving cell (or the PCI of the serving cell). As a variation, the cells of set #D may also be associated with the additional cell (or the PCI of the additional cell).

[0252] Alternatively, the cells of set #D may also be associated only with a specific serving cell (or a PCI of a specific serving cell). The specific serving cell may also be a SpCell / PUCCH-SCell. As a variation, the cells of set #D may also be associated with a SCell (or a PCI of a SCell).

[0253] Fig.13 An example of set #D is shown. Here, a case where the cells included in set #D are serving cells (here, SpCell#0, SCell#1, and SCell#2) is shown.

[0254] When L1 beam measurement / reporting is set for a candidate cell / serving cell, the cells included in the candidate cells (e.g., set #B) for which L1 beam measurement / reporting is set and the cells included in set #D (e.g., set #D including only serving cells) are also in different situations (see Fig.13 ). In this case, the relationship between set #B and set #D needs to be properly controlled. In addition, the relationship between other sets #A / #C / #M and set #D needs to be properly controlled.

[0255] The UE may also receive first information related to one or more serving cells for which L1 beam measurement and reporting is set (for example, information of cells included in set #D), second information related to one or more candidate cells for which L1 beam measurement and reporting is set (for example, information of cells included in other sets #A / #B / #C / #M), and third information (for example, MAC CE / DCI) for indicating deactivation of at least one of the serving cell and the candidate cell. The UE may also control L1 beam measurement and reporting of the serving cell and the candidate cell based on the first information, the second information, and the third information.

[0256] The relationship between set #D and sets #A / #B / #C / #M shown in the second embodiment may be defined / set based on at least one of options 4-2 and 4-3.

[0257] [Option 4-2]

[0258] In a case where at least one of the cells (eg, serving cells) included in set #D is deactivated, at least one of the following options 4-2A and 4-2B may also be applied.

[0259] Option 4-2A

[0260] When a cell included in set #D is deactivated, it can also be controlled so that L1 beam measurement / report (or CSI measurement / report) associated with the deactivated cell is not performed. In addition, it can also be controlled so that L1 beam measurement (or CSI measurement) is performed without L1 beam reporting (or CSI reporting).

[0261] Fig.14 The case where set #D includes SpCell#0, SCell#1, and SCell#2, and set #B includes SpCell#0, candidate cells #0-1, #0-2, #0-3, SCell#1, candidate cells #1-1, SCell#2, candidate cells #2-1, and #2-2 is shown. Alternatively, set #B may include only candidate cells (or no serving cells).

[0262] exist Fig.14 , it is shown that SCell#1 included in set #D is deactivated.

[0263] When SCell#1 is deactivated, it can also be controlled so that the L1 beam measurement / report (or CSI measurement / report) associated with the SCell#1 is not performed. The L1 beam measurement / report (or CSI measurement / report) associated with SCell#1 can also be at least one of the L1 beam measurement / report (or CSI measurement / report) of the SCell#1, the L1 beam measurement / report (or CSI measurement / report) of the candidate cell associated with the SCell#1, and the L1 beam measurement / report (or CSI measurement / report) of the candidate cell corresponding to the frequency of the SCell#1.

[0264] When the L1 beam measurement / report of candidate cell #1-1 is set in SCell#1 (for example, set in a high-layer parameter associated with SCell#1) and SCell#1 is deactivated, the L1 beam measurement result of at least one of SCell#1 and candidate cell #1-1 may not be reported. For example, when SCell#1 is deactivated, the UE may not be requested to perform L1 beam measurement / report of SCell#1 and candidate cell #1-1.

[0265] Even when SCell#1 is deactivated, when the cell setting and L1 beam measurement / report of candidate cell #1-1 are independent of (or not associated with) the cell setting of SCell#1, L1 beam measurement / report of candidate cell #1-1 may be performed. For example, the UE may also control not to report the L1 beam measurement result of the deactivated SCell#1, but to report the L1 beam measurement result of the candidate cell #1-1.

[0266] Option 4-2B

[0267] The L1 beam report associated with the deactivated cell may also be performed in other cells (e.g., serving cells). For example, when SCell#1 is deactivated, the UE may also control the L1 beam measurement results of at least one of SCell#1 and candidate cell#1-1 to be reported in other cells (e.g., SpCell#0 / SCell#2).

[0268] [Option 4-3]

[0269] When at least one of the candidate cells is deactivated, at least one of the following options 4-3A and 4-3B may be applied. The candidate cell may be at least one of the candidate cells included in set #B, the target cell for L1 beam measurement / reporting, and the candidate cell to be the handover destination.

[0270] Option 4-3A

[0271] When one of the candidate cells is deactivated, it can also be controlled so that L1 beam measurement / report (or CSI measurement / report) associated with the deactivated cell is not performed. In addition, it can also be controlled so that L1 beam measurement (or CSI measurement) is performed but L1 beam reporting (or CSI reporting) is not performed.

[0272] Fig.15The case where set #D includes SpCell#0, SCell#1, and SCell#2, and set #B includes SpCell#0, candidate cells #0-1, #0-2, #0-3, SCell#1, candidate cells #1-1, SCell#2, candidate cells #2-1, and #2-2 is shown. Alternatively, set #B may include only candidate cells (or no serving cells).

[0273] exist Fig.15 , it is shown that the candidate cell 1-1 included in the set #B is deactivated.

[0274] When candidate cell #1-1 is deactivated, it can also be controlled so that L1 beam measurement / report (or CSI measurement / report) of candidate cell #1-1 is not performed. In this case, the UE can also be controlled so that L1 beam measurement / report (or CSI measurement / report) corresponding to the serving cell (here, SCell#1) associated with candidate cell #1-1 is performed.

[0275] Option 4-3B

[0276] In the case where one of the candidate cells is deactivated, the L1 beam measurement / report (or CSI measurement / report) of the deactivated cell may also continue. For example, in the case where candidate cell #1-1 is deactivated, the UE may also be controlled to perform L1 beam measurement (or CSI measurement) of the candidate cell #1-1 and report the measurement result.

[0277] In this embodiment, “not reported” may also mean “reducing the UCI payload and not reporting”, or “not reporting while maintaining the UCI payload (for example, replacing dummy UCI bits)”.

[0278] In addition, in this embodiment, the relationship between set #D and set #B can also be applied to the relationship between set #D and sets #A / #C / #M. In this case, set #B can also be replaced with set #A / #C / #M.

[0279] [change]

[0280] Option 4-2 / Option 4-3 can also be applied to the case where set #D (for example, SCell #1) is not configured (or the case where the serving cell corresponding to the frequency of the candidate cell is not configured).

[0281] Fig.16The case where set #D includes SpCell #0 and SCell #2, and set #B includes SpCell #0, candidate cells #0-1, #0-2, SCell #1, candidate cells #1-1, SCell #2, candidate cells #2-1, and #2-2 is shown. Alternatively, set #B may include only candidate cells (or no serving cells). In this case, option 4-2 / option 4-3 may also be applied.

[0282] In this case, it may be a structure in which L1 beam measurement / reporting of candidate cell #1-1 is not supported or allowed (option 4-3A').

[0283] Alternatively, it may be a structure that supports or allows L1 beam measurement / reporting of candidate cell #1-1 (option 4-3B'). In this case, the RRC settings related to the L1 beam report of candidate cell #1-1 may also be set in other cells. Other cells may also be, for example, service cells corresponding to other frequencies / non-service cells corresponding to other frequencies / non-service cells corresponding to the same frequency. In addition, the L1 beam measurement results (or CSI measurement results) of candidate cell #1-1 may also be reported in other cells. Other cells may also be, for example, service cells corresponding to other frequencies / non-service cells corresponding to other frequencies / non-service cells corresponding to the same frequency.

[0293] In addition, the above-mentioned specific UE capabilities can be capabilities that are applied across all duplex modes (commonly regardless of the duplex mode) or capabilities of each duplex mode (for example, time division duplex (TDD) and frequency division duplex (FDD)).

[0294] Furthermore, at least one of the above-mentioned embodiments may be applied to a case where specific information associated with the above-mentioned embodiments is set to the UE through higher layer signaling.

[0322] (Wireless Communication System)

[0323] 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.

[0324] Fig.17 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 through Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the fifth generation mobile communication system New Radio (5GNR), or the like.

[0325] 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.

[0326] 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.

[0327] 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)).

[0328] 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.

[0329] 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).

[0330] 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 (lower than 6 GHz (sub-6 GHz)), and FR2 may be a frequency band higher than 24 GHz (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.

[0331] 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).

[0332] 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.

[0333] 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.

[0334] The core network 30 may also include network functions (NF) such as User Plane Function (UPF), Access and Mobility Management Function (AMF), Session Management Function (SMF), Unified Data Management (UDM), Application Function (AF), Data Network (DN), Location Management Function (LMF), Operation, Administration and Maintenance (Management) (OAM), etc. In addition, multiple functions may be provided by one network node. In addition, communication with an external network (e.g., the Internet) may also be performed via the DN.

[0335] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0336] 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.

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.

[0420] 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.

[0421] 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.

[0422] 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.

[0423] 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.

[0424] 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.

[0425] 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.

[0426] 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.

[0427] 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.

[0428] 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.

[0429] 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.

[0430] 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.

[0431] 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".

[0432] 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.

[0433] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​relative to a specific value, or other corresponding information. For example, wireless resources may also be indicated by a specific index.

[0434] In the present disclosure, the names used for parameters, etc. are not restrictive in all respects. Furthermore, the mathematical formulas, etc. using these parameters may be different from those explicitly disclosed in the present disclosure. Various channels (PUCCH, PDCCH, etc.) and information elements can be identified by any suitable names, and therefore, the various names assigned to these various channels and information elements are not restrictive in all respects.

[0435] Information, signals, etc. described in this disclosure may also be represented using any of a variety of different techniques. 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.

[0436] 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.

[0437] 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.

[0438] The notification of information is not limited to the methods / 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.

[0439] 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)).

[0440] 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).

[0441] 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).

[0442] 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.

[0443] In addition, software, instructions, information, etc. may also be sent and received via a transmission medium. For example, when software is sent from a website, server, or other remote source using at least one of wired technology (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and wireless technology (infrared, microwave, etc.), at least one of these wired technology and wireless technology is included in the definition of transmission medium.

[0444] The terms "system" and "network" used in the present disclosure can be used interchangeably. "Network" may also refer to a device (eg, a base station) included in the network.

There are also cases where base stations are referred to by terms such as macro cell, small cell, micro-micro cell, and micro-micro cell.

[0447] A base station can accommodate one or more (for example, three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area can also provide communication services through a base station subsystem (for example, a small base station for indoor use (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a part or the entirety of the coverage area of ​​at least one of a base station and a base station subsystem that provides communication services within the coverage area.

[0448] In the present disclosure, a case where a base station sends information to a terminal and a case where the base station instructs the terminal to control / operate based on the information may be mutually rewritten.

[0449] In the present disclosure, terms such as “mobile station (MS)”, “user terminal”, “user device (User Equipment (UE))”, and “terminal” can be used interchangeably.

For example, various information is sent and received between external devices via wireless communication. The communication module 60 can be located either inside or outside the electronic control unit 49. The external device can also be, for example, the above-mentioned base station 10, user terminal 20, etc. In addition, the communication module 60 can also be, for example, at least one of the above-mentioned base station 10 and user terminal 20 (it can also function as at least one of the base station 10 and user terminal 20).

[0463] The communication module 60 may also transmit at least one of the signals from the various sensors 50-58 input to the electronic control unit 49, information obtained based on the signals, and information based on input from the outside (user) obtained via the information service unit 59 to an external device via wireless communication.

[0466] In addition, the base station in the present disclosure may also be rewritten as a user terminal. For example, the various methods / implementations of the present disclosure may also be applied to a structure in which the communication between a base station and a user terminal is rewritten as communication between multiple user terminals (for example, it may also be referred to as device-to-device (D2D)), vehicle-to-everything (V2X), etc.). In this case, it may also be set as a structure in which the user terminal 20 has the functions possessed by the above-mentioned base station 10. In addition, terms such as "uplink" and "downlink" may also be rewritten as terms corresponding to inter-terminal communication (for example, "sidelink"). For example, uplink channels, downlink channels, etc. may also be rewritten as sidelink channels.

[0467] Likewise, the user terminal in the present disclosure may be rewritten as a base station. In this case, the base station 10 may have the functions of the user terminal 20 described above.

[0468] In the present disclosure, operations are assumed to be performed by a base station, and sometimes by its upper node depending on the situation. Obviously, in a network including one or more network nodes having a base station, various operations performed for communication with a terminal can be performed by a base station, one or more network nodes other than the base station (for example, Mobility Management Entity (MME)), Serving-Gateway (S-GW), etc., but not limited to these), or a combination thereof.

[0469] The various methods / implementations described in this disclosure may be used individually or in combination, and may be used in a switched manner as the method is executed.

In addition, multiple systems can also be applied in combination (for example, LTE or LTE-A, combination with 5G, etc.).

[0471] The phrase “based on” used in the present disclosure does not mean “based only on” unless otherwise specified. In other words, the phrase “based on” means both “based only on” and “based at least on”.

[0472] 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.

[0473] The term "determining" used in the present disclosure may include a variety of operations. 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".

[0474] 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)".

[0475] In addition, "judgment (decision)" can also refer to situations where resolving, selecting, choosing, establishing, comparing, etc. are regarded as "judgment (decision)". That is, "judgment (decision)" can also refer to situations where some operations are regarded as "judgment (decision)".

[0476] In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)" and so on.

[0477] The "maximum transmit power" recorded in the present disclosure may refer to the maximum value of the transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0478] 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".

[0479] 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.

[0480] 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".

[0481] 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.

[0482] 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.

[0483] In the present disclosure, "below", "less than", "above", "more than", "equal to", etc. may also be rephrased with each other. Furthermore, in the present disclosure, words meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. may also be rephrased with each other without being limited to the original degree, comparative degree and superlative degree. Furthermore, in the present disclosure, words meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. may also be rephrased with each other as expressions with "ith (i is an arbitrary integer)" added thereto without being limited to the original degree, comparative degree and superlative degree (for example, "highest" may also be rephrased with "i-th highest").

[0484] In the present disclosure, “of,” “for,” “regarding,” “related to,” “associated with,” etc. may also be replaced by each other.

[0485] 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.
