DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (Dynamic grant-based transmission and configuration grant-based transmission (Type 1, Type 2)) Regarding UL transmission in NR, dynamic grant-based transmission and configured grant-based transmission are being considered.

[0012] The dynamic grant-based transmission is a method of performing UL transmission using an uplink shared channel (for example, a Physical Uplink Shared Channel (PUSCH)) based on a dynamic UL grant (dynamic grant, dynamic UL grant).

[0013] The configured grant-based transmission is a method of performing UL transmission using an uplink shared channel (e.g., PUSCH) based on a UL grant (which may be called a configured grant or a configured UL grant, etc.) configured by a higher layer. In the configured grant-based transmission, UL resources are already assigned to the UE, and the UE can perform UL transmission autonomously using the configured resources, so that low-latency communication can be realized.

[0014] Dynamic grant-based transmission may also be referred to as dynamic grant-based PUSCH, UL Transmission with dynamic grant, PUSCH with dynamic grant, UL Transmission with UL grant, UL grant-based transmission, UL transmission scheduled (transmission resources are configured) by dynamic grant, etc.

[0015] The configured grant-based transmission may also be referred to as configured grant-based PUSCH, UL Transmission with configured grant, PUSCH with configured grant, UL Transmission without UL grant, UL grant-free transmission, UL transmission scheduled by a configured grant (transmission resources are configured), etc.

[0016] Also, the configuration grant-based transmission may be defined as one type of UL Semi-Persistent Scheduling (SPS). In the present disclosure, the "configuration grant" may be read as "SPS", "SPS / configuration grant", and the like.

[0017] Several types (Type 1, Type 2, etc.) of configuration grant-based transmission are being considered.

[0018] In configured grant type 1 transmission (type 1 configuration grant), parameters used for configured grant-based transmission (which may also be called configured grant-based transmission parameters, configured grant parameters, configured grant (CG) configuration, configuration information, etc.) are configured in the UE using only higher layer signaling.

[0019] In a configured grant type 2 transmission, configuration grant parameters are configured in the UE by higher layer parameters (e.g., Radio Resource Control (RRC) parameters). In a configured grant type 2 transmission, at least a part of the configuration grant parameters may be notified to the UE by physical layer signaling (e.g., Downlink Control Information (DCI) for activation, which will be described later).

[0020] The configured grant parameters may be configured in the UE using at least one of a higher layer parameter (e.g., an RRC information element (IE) "ConfiguredGrantConfig") and DCI. The configured grant parameters may include, for example, information identifying the configured grant resource. The configured grant parameters may include, for example, an index (or identifier (ID)) of the configured grant, a time offset, a periodicity, a number of repeated transmissions of a transport block (TB) (also referred to as an aggregation factor, number of repetitions, number of aggregations, etc.), a redundancy version (RV) sequence used in the repeated transmission, the above-mentioned timer, etc.

[0021] Here, the period and the time offset may be expressed in units of a symbol, a slot, a subframe, a frame, etc. The period may be indicated, for example, by a predetermined number of symbols. The time offset may be indicated, for example, by an offset relative to the timing of a predetermined index (such as slot number=0 and / or system frame number=0). The number of repeated transmissions may be any integer, for example, 1, 2, 4, 8, etc. If the number of repeated transmissions is n (>0), the UE may transmit the configured grant-based PUSCH for a predetermined TB using n transmission opportunities.

[0022] If the UE is configured for configured grant type 1 transmission, the UE may determine that one or more configured grants are triggered. The UE may perform PUSCH transmission without a dynamic grant using the configured resources for configured grant-based transmission (which may also be called configured grant resources, transmission occasions, etc.). Even if the configured grant-based transmission is configured, the UE may skip the configured grant-based transmission if there is no data in the transmission buffer.

[0023] When the UE is configured with configuration grant type 2 transmission and is notified of a predetermined activation signal, the UE may determine that one or more configuration grants are triggered (or activated). The predetermined activation signal (e.g., DCI for activation) may be DCI (PDCCH) that is CRC (Cyclic Redundancy Check) scrambled with a predetermined identifier (e.g., CS-RNTI: Configured Scheduling RNTI). Note that the DCI may be used to control deactivation, retransmission, etc. of the configuration grant.

[0024] The UE may determine whether to transmit PUSCH using the configured grant resource configured by the higher layer based on the above-mentioned predetermined activation signal. The UE may release (may be called "release", "deactivate", etc.) the resource (PUSCH) corresponding to the configured grant based on the DCI that deactivates the configured grant or the expiration of a predetermined timer (the passage of a predetermined time).

[0025] The UE may transmit the PUSCH without a dynamic grant using the activated resource for the configuration grant-based transmission (which may be called a configuration grant resource, a transmission occasion, etc.). Even if the configuration grant-based transmission is activated (is in an active state), the UE may skip the configuration grant-based transmission if there is no data in the transmission buffer.

[0026] Each of the dynamic grant and the configuration grant may be called an actual UL grant. That is, the actual UL grant may be higher layer signaling (e.g., “ConfiguredGrantConfig” of the RRC IE), physical layer signaling (e.g., the above-mentioned predetermined activation signal), or a combination thereof.

[0027] In NR, repeated PUSCH transmission by configuration grant is being considered. Specifically, in NR, transmission of a transport block (TB) based on the same data at one or more transmission opportunities is being considered.

[0028] The repeated transmission may be called slot-aggregation transmission, multi-slot transmission, TB repetition, etc. The number of repetitions (also called aggregation number, aggregation factor, repetition factor, etc.) K may be specified to the UE by at least one of a higher layer parameter (e.g., "repK" of an RRC IE) and a DCI. The number of repetitions K may be, for example, 1, 2, 4, or 8. Note that the number of repetitions=1 may mean that the transmission is performed once without repetition.

[0029] The same symbol allocation may be applied among K repetitions (also called K transmission opportunities, K consecutive slots, etc.). Meanwhile, the redundancy version (RV) applied to TBs based on the same data among K repetitions may be the same or at least partially different.

[0030] For example, the RV applied to the TB at the nth (n=1, 2, ..., K)th transmission opportunity may be determined based on an RV sequence set by a higher layer parameter (e.g., "repK-RV" in the RRC IE). The RV sequence may be, for example, {0, 2, 3, 1}, {0, 3, 0, 3}, or {0, 0, 0, 0}.

[0031] The UE may determine an RV value to be applied to the TB of the nth transmission opportunity from the configured RV sequence according to a predetermined rule. For example, the UE may determine an RV value to be applied to the TB of the nth transmission opportunity as the (mod(n-1,4)+1)th value in the RV sequence.

[0032] The transmission opportunity at which the first transmission of the TB begins may be determined, for example, according to the following rules. If the RV sequence is {0,2,3,1}, the first transmission opportunity of K repetitions If the set RV sequence is {0,3,0,3}, then any transmission opportunity with RV=0 in K repetitions If the set RV sequence is {0,0,0,0}, any transmission opportunity except the last transmission opportunity for K=8

[0033] (TCI, spatial relations, QCL) In NR, it is considered to control reception processing (e.g., at least one of reception, demapping, demodulation, and decoding) and transmission processing (e.g., at least one of transmission, mapping, precoding, modulation, and encoding) in a UE of at least one of a signal and a channel (referred to as a signal / channel) based on a transmission configuration indication state (TCI state).

[0034] The TCI state may represent a state that is applied to a downlink signal / channel. The equivalent of the TCI state that is applied to an uplink signal / channel may be expressed as a spatial relation.

[0035] The TCI state is information on the Quasi-Co-Location (QCL) of signals / channels, and may be called spatial reception parameters, spatial relation information, etc. The TCI state may be configured in the UE for each channel or for each signal.

[0036] A QCL is an index that indicates the statistical properties of a signal / channel. For example, when a signal / channel and another signal / channel are in a QCL relationship, it may mean that it can be assumed that at least one of the following is the same (QCL with respect to at least one of the following) between these different signals / channels: Doppler shift, Doppler spread, average delay, delay spread, and spatial parameter (e.g., spatial Rx parameter).

[0037] In addition, the spatial reception parameters may correspond to a reception beam (e.g., a reception analog beam) of the UE, and the beam may be specified based on a spatial QCL. A QCL (or at least one element of a QCL) in the present disclosure may be replaced with a spatial QCL (sQCL).

[0038] A plurality of types (QCL types) of QCL may be defined. For example, four QCL types AD may be provided, each having different parameters (or parameter sets) that can be assumed to be the same. The parameters (which may be called QCL parameters) are as follows: QCL Type A (QCL-A): Doppler shift, Doppler spread, mean delay and delay spread, QCL type B (QCL-B): Doppler shift and Doppler spread, QCL type C (QCL-C): Doppler shift and mean delay, · QCL type D (QCL-D): spatial reception parameters.

[0039] The UE's assumption that a Control Resource Set (CORESET), channel, or reference signal is in a particular QCL (e.g., QCL type D) relationship with another CORESET, channel, or reference signal may be referred to as a QCL assumption.

[0040] The UE may determine at least one of a transmit beam (Tx beam) and a receive beam (Rx beam) for a signal / channel based on the TCI condition or QCL assumptions of the signal / channel.

[0041] The TCI state may be, for example, information about the QCL of the channel of interest (in other words, the Reference Signal (RS) for that channel) and another signal (e.g., another RS). The TCI state may be set (indicated) by higher layer signaling, physical layer signaling, or a combination of these.

[0042] The physical layer signaling may be, for example, Downlink Control Information (DCI).

[0043] The channel for which the TCI state or spatial relationship is set (specified) may be, for example, at least one of a downlink shared channel (Physical Downlink Shared Channel (PDSCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), an uplink shared channel (Physical Uplink Shared Channel (PUSCH)), and an uplink control channel (Physical Uplink Control Channel (PUCCH)).

[0044] In addition, the RS that has a QCL relationship with the channel may be, for example, at least one of a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), a tracking CSI-RS (also called a tracking reference signal (TRS)), and a QCL detection reference signal (also called a QRS).

[0045] An SSB is a signal block including at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). An SSB may be referred to as an SS / PBCH block.

[0046] An RS of QCL type X in a TCI state may refer to an RS that has a QCL type X relationship with a certain channel / signal (its DMRS), and this RS may be called a QCL source of QCL type X in the TCI state.

[0047] (unified / common TCI framework) The unified TCI framework allows UL and DL channels to be controlled by a common framework. Instead of specifying the TCI state or spatial relationship for each channel as in Rel.15, the unified TCI framework may specify a common beam and apply it to all UL and DL channels, or a common beam for UL may apply to all UL channels and a common beam for DL ​​may apply to all DL channels.

[0048] One common beam for both DL and UL, or one common beam for DL ​​and one common beam for UL (total of two common beams) are considered.

[0049] The UE may assume the same TCI state (joint TCI state, joint TCI state pool, joint common TCI state pool) for UL and DL.

[0050] The RRC may configure multiple TCI states for both DL and UL (a joint common TCI state pool). Each of the multiple TCI states may be SSB, CSI-RS, or SRS. The MAC CE may activate a portion (set, pool) of the configured multiple TCI states. The DCI may indicate at least one of the activated multiple TCI states.

[0051] The UL and DL default beams may be aligned via MAC CE based beam management (MAC CE level beam instructions). The default TCI state of the PDSCH may be updated to align with the default UL beam (spatial relationship).

[0052] A common beam / unified TCI state may be indicated from the same TCI state pool for both UL and DL (joint common TCI state pool) by DCI based beam management (DCI level beam indication). M (>1) TCI states may be activated by the MAC CE. The UL / DL DCI may select one out of M active TCI states. The selected TCI state may be applied to both UL and DL channels / RS.

[0053] The UE may assume different TCI states for each of the UL and DL (separate TCI state, separate TCI state pool, UL separate TCI state pool and DL separate TCI state pool, separate common TCI state pool, UL common TCI state pool and DL common TCI state pool).

[0054] The RRC (parameters, information elements) may configure multiple TCI states (pools) for each of the UL and DL channels.

[0055] The MAC CE may select (activate) one or more (eg, multiple) TCI states (sets, pools) for each of the UL and DL channels. The MAC CE may activate two sets of TCI states.

[0056] The DL DCI may select (indicate) one or more (e.g., one) TCI states. This TCI state may apply to one or more DL channels. The DL channel may be PDCCH / PDSCH / CSI-RS. The UE may determine the TCI state for each DL channel / RS using the Rel.16 TCI state behavior (TCI framework).

[0057] The UL DCI may select (indicate) one or more (e.g., one) TCI states, which may apply to one or more UL channels, which may be PUSCH / SRS / PUCCH.

[0058] It is expected that more scenarios with different requirements will be considered, such as multi-TRP transmission, high speed train (HST) transmission, inter-cell mobility during which a UE may connect to two cells, etc., the common beam for each TRP, cell, may be different.

[0059] In this case, the UE may be equipped with multiple panels for FR2, where the common beam for each UE panel may be different.

[0060] For DCI indication of a common beam (common TCI state), a TCI field in the DL DCI may be reused, or a new field in the DL DCI (e.g., a unified TCI field) may be used. The DL DCI, the DCI for PDSCH scheduling, and the DCI formats 1_1 and 1_2 may be interchangeable.

[0061] A new field (eg, a unified TCI field) in the UL DCI may be used for DCI indication of a common beam (common TCI state). The UL DCI, the DCI for PUSCH scheduling, and the DCI formats 0_1 and 0_2 may be interchangeable.

[0062] (Multi-TRP) In NR, it is considered that one or more transmission / reception points (TRPs) (multi-TRPs (MTRPs)) will perform DL transmission to a UE using one or more panels (multi-panels). It is also considered that a UE will perform UL transmission to one or more TRPs using one or more panels.

[0063] Note that multiple TRPs may correspond to the same cell identifier (cell identifier (ID)) or different cell IDs. The cell ID may be a physical cell ID or a virtual cell ID.

[0064] Multi-TRP (e.g., TRP#1, #2) may be connected by ideal / non-ideal backhaul to exchange information, data, etc. Each TRP of the multi-TRP may transmit a different code word (CW) and a different layer. Non-Coherent Joint Transmission (NCJT) may be used as a form of multi-TRP transmission.

[0065] In the NCJT, for example, TRP#1 performs modulation mapping and layer mapping on a first codeword to transmit a first PDSCH using a first number of layers (e.g., two layers) with a first precoding, and TRP#2 performs modulation mapping and layer mapping on a second codeword to transmit a second PDSCH using a second number of layers (e.g., two layers) with a second precoding.

[0066] In addition, multiple PDSCHs (multi-PDSCHs) that are NCJTed may be defined as partially or completely overlapping with respect to at least one of the time and frequency domains. That is, the first PDSCH from the first TRP and the second PDSCH from the second TRP may overlap with at least one of the time and frequency resources.

[0067] The first PDSCH and the second PDSCH may be assumed to be not quasi-co-located (QCL). Reception of multiple PDSCHs may be interpreted as simultaneous reception of PDSCHs that are not of a certain QCL type (e.g., QCL type D).

[0068] Multiple PDSCHs from multiple TRPs (which may be referred to as multiple PDSCHs) may be scheduled using one DCI (single DCI, single PDCCH) (single-master mode, single-DCI based multi-TRP). Multiple PDSCHs from multiple TRPs may be scheduled using multiple DCIs (multiple DCI, multiple PDCCHs) respectively (multi-master mode, multi-DCI based multi-TRP).

[0069] Such a multi-TRP scenario allows for more flexible transmission control using channels with better quality.

[0070] In order to support intra-cell (having the same cell ID) and inter-cell (having different cell IDs) multi-TRP transmission based on multiple PDCCHs, in the RRC configuration information for linking multiple pairs of PDCCHs and PDSCHs having multiple TRPs, one control resource set (CORESET) in the PDCCH configuration information (PDCCH-Config) may correspond to one TRP.

[0071] Improvements in the reliability and robustness of PUSCH using multi-TRP / multi-panel are being studied.

[0072] The configured grant configuration (ConfigureGrantConfig) information element (IE) is used to configure uplink transmission (configured grant transmission, configured grant PUSCH) according to two schemes without using dynamic grant. The actual UL grant may be configured by lending RRC (type 1) or may be provided via PDCCH (addressed to configured scheduling (CS)-radio network temporary identifier (RNTI)) (type 2). Multiple configured grant configurations may be configured in one bandwidth part (BWP) of one serving cell.

[0073] The configured grant configuration may include at least one of parameters for Type 1 and Type 2, such as a power control loop to use parameter (powerControlLoopToUse, closed loop index, power control adjustment state), a P0-PUSCH alpha set index (p0-PUSCH-Alpha), and a parameter for Type 1 (rrc-ConfiguredUplinkGrant). The rrc-ConfiguredUplinkGrant may include at least one of an antenna port parameter (antennaPort), a precoding and number of layers parameter (precodingAndNumberOfLayers), an SRS resource indicator (SRI, srs-ResourceIndicator), and a path loss reference index (path loss reference RS, PL-RS, pathlossReferenceIndex).

[0074] For scheduling activation or deactivation, the UE verifies a DL semi-persistent scheduling (SPS) assignment PDCCH or a configured UL grant type 2 PDCCH, in which case the cyclic redundancy check (CRC) of the corresponding DCI format is scrambled using the CS-RNTI.

[0075] In Rel.16, multiple configuration grants are not associated with a TRP or UE panel. In Rel.17 and later, it is unclear how the configuration grants are used in the case of multiple TRPs / multiple UE panels. If the relationship between the configuration grants and multiple TRPs / multiple UE panels is not clear, communication throughput, communication quality, etc. may be degraded.

[0076] Therefore, the present inventors have conceived a method of controlling TRP (UE panel, spatial relationship) for configuration grant transmission.

[0101] According to the above-described first embodiment, a plurality of CG settings corresponding to a plurality of TRP / UE panels respectively can be appropriately set.

[0102] <Second embodiment> Each CG configuration is associated with multiple TRP / UE panels. Each CG PUSCH based on one CG configuration may be associated with one TRP / UE panel.

[0103] In one CG configuration, multiple fields (values) of a specific parameter may be configured. In a PDCCH (DCI having a CRC scrambled by the CS-RNTI) addressed to a CS-RNTI for type 2 CG (activation), multiple fields (values) of a specific parameter may be indicated. Multiple fields may be associated with multiple TRP / UE panels, respectively. The specific parameter may be at least one of a power control loop to use parameter (powerControlLoopToUse), a P0-PUSCH alpha set index (p0-PUSCH-Alpha), an antenna port parameter (antennaPort), a precoding and number of layers parameter (precodingAndNumberOfLayers), an SRS resource indicator (srs-ResourceIndicator), and a pathloss reference index (pathlossReferenceIndex).

[0104] According to the above-described second embodiment, it is possible to appropriately set a plurality of CG PUSCHs corresponding to a plurality of TRP / UE panels, respectively.

[0105] <Third embodiment> In the second embodiment, when multiple fields (values) of a particular parameter are set / indicated, the question arises how the different fields are mapped to different PUSCH (transmission) occasions.

[0106] The UE may follow any of the following aspects 3-1 to 3-3.

[0107] <<Aspect 3-1>> Different values ​​of a particular parameter are mapped to different CG periodicities.

[0108] The same value of a particular parameter may be applied to all PUSCH occasions (repetitions) within a CG period. When PUSCH repetition type A / type B is configured / indicated, aspect 3-1 may be applied.

[0109] The mapping between multiple values ​​of a particular parameter and multiple CG periods may follow the following mapping pattern: [Mapping pattern] A first value of the particular parameter is applied to the first X CG periods, a second value of the particular parameter is applied to the second X CG periods, and an nth value of the particular parameter is applied to the nth X CG periods. The same mapping pattern continues for subsequent CG periods. The mapping pattern may be periodic and continuous.

[0110] For PUSCH repetition type B, one PUSCH occasion (repetition) may refer to one nominal (configured / instructed) repetition or one actual (transmitted) repetition.

[0111] In the example of Figure 1A, PUSCH repetition is not configured / indicated, X is 1, two values ​​of the specific parameter are configured / indicated, and one PUSCH is transmitted per CG period. The first value of the specific parameter applies to the 1st, 3rd, ...th CG periods (and the PUSCHs therein). The second value of the specific parameter applies to the 2nd, 4th, ...th CG periods (and the PUSCHs therein).

[0112] In the example of Figure 1B, PUSCH repetitions are set / indicated, X is 1, two values ​​of the specific parameter are set / indicated, and two PUSCH repetitions are transmitted per CG period. The first value of the specific parameter applies to the 1st, 3rd, ...th CG periods (within which PUSCH repetitions). The second value of the specific parameter applies to the 2nd, 4th, ...th CG periods (within which PUSCH repetitions).

[0113] "Aspect 3-2" Different values ​​of a particular parameter are mapped to different PUSCH occasions (repetitions) within one CG period.

[0114] When PUSCH repetition type A / type B is configured / indicated, aspect 3-2 may be applied.

[0115] The mapping between multiple values ​​and multiple repetitions of a particular parameter may follow the following mapping pattern: [Mapping pattern] The first value of the particular parameter is applied to the first X PUSCH repetitions (occasions), the second value of the particular parameter is applied to the second X PUSCH repetitions (occasions), and the nth value of the particular parameter is applied to the nth X PUSCH repetitions (occasions). The same mapping pattern continues for subsequent PUSCH repetitions (occasions) within one CG period. The xth PUSCH repetition (occasion) may be counted within a CG period.

[0116] For PUSCH repetition type B, one PUSCH occasion (repetition) may refer to one nominal (configured / instructed) repetition or one actual (transmitted) repetition.

[0117] In the example of Figure 2, PUSCH repetitions are set / indicated, X is 1, two values ​​of a specific parameter are set / indicated, and three actual repetitions are transmitted in one CG period. The first value of the specific parameter applies to the first and third repetitions in each CG period. The second value of the specific parameter applies to the second repetition in each CG period.

[0118] "Aspect 3-3" Different values ​​of a particular parameter are mapped to different PUSCH occasions (repetitions) spanning multiple CG periods.

[0119] Example 3-3 may be applied when PUSCH repetition type A / type B is configured / indicated. Example 3-3 may be applied when PUSCH repetition type A / type B is not configured / indicated.

[0120] The mapping between multiple values ​​of a particular parameter and multiple PUSCH occasions may follow the following mapping pattern. [Mapping pattern] The first value of the particular parameter is applied to the first X PUSCH occasions (repetitions), the second value of the particular parameter is applied to the second X PUSCH occasions (repetitions), and the nth value of the particular parameter is applied to the nth X PUSCH occasions (repetitions). The same mapping pattern continues for subsequent PUSCH occasions (repetitions). The xth PUSCH occasion (repetition) may be counted across multiple CG periods.

[0121] For PUSCH repetition type B, one PUSCH occasion (repetition) may refer to one nominal (configured / instructed) repetition or one actual (transmitted) repetition.

[0122] In the example of Figure 3, PUSCH repetitions are configured / indicated, X is 1, two values ​​of a specific parameter are configured / indicated, and three actual repetitions are transmitted in one CG period. The first value of the specific parameter applies to the 1st, 3rd, 5th, ... repetitions counted across multiple CG periods. The second value of the specific parameter applies to the 2nd, 4th, 6th, ... repetitions counted across multiple CG periods.

[0123] <<Variation>> In aspects 3-1, 3-2 and 3-3, the CG period, slot and sub-slot may be read as interchangeable.

[0124] If CG repetition is not configured, there may be one PUSCH occasion per CG period. If CG repetition is configured, there may be multiple PUSCH occasions per CG period.

[0125] [Modification of embodiment 3-1] Multiple values ​​of a particular parameter are mapped to multiple slots.

[0126] In the example of Figure 4, PUSCH repetition is not set / indicated, X is 1, two values ​​of the specific parameter are set / indicated, the CG period is 7 symbols (subslots), and two PUSCHs are transmitted per slot. The first value of the specific parameter applies to the 1st, 3rd, ...th slots (and the PUSCHs therein). The second value of the specific parameter applies to the 2nd, 4th, ...th slots (and the PUSCHs therein).

[0127] [Modification of embodiment 3-2] Multiple values ​​of a particular parameter are mapped to multiple PUSCH occasions (repetitions) within one slot, where the xth PUSCH occasion (repetition) is counted within one slot.

[0128] In the example of Figure 5, PUSCH repetitions are set / indicated, X is 1, two values ​​of a specific parameter are set / indicated, and three actual repetitions are transmitted in one slot. The first value of the specific parameter applies to the first and third repetitions (occasions) in each slot. The second value of the specific parameter applies to the second repetition (occasion) in each slot.

[0129] [Modification of embodiment 3-3] Multiple values ​​of a particular parameter are mapped to multiple PUSCH occasions (repetitions), with the xth PUSCH occasion (repetition) being counted across multiple slots.

[0130] In the example of Figure 6, PUSCH repetitions are configured / indicated, X is 1, two values ​​of a specific parameter are configured / indicated, and three actual repetitions are transmitted in one slot. The first value of the specific parameter applies to the 1st, 3rd, 5th, ...th repetitions (occasions) counted across multiple slots. The second value of the specific parameter applies to the 2nd, 4th, 6th, ...th repetitions (occasions) counted across multiple slots.

[0131] These variations may be applied when the CG period is shorter than one slot, may be applied when the CG period is equal to one slot, or may be applied when the CG period is longer than one slot.

[0132] In aspects 3-1 to 3-3 and variations thereof, X may be an integer equal to or greater than 1. Multiple mapping patterns (i.e., values ​​of X) may be supported and configured by RRC signaling.

[0133] Among aspects 3-1 to 3-3 and variations thereof, multiple aspects (options) may be supported and configured by RRC signaling.

[0134] According to the above third embodiment, multiple values ​​of a specific parameter can be appropriately mapped to multiple PUSCH occasions.

[0135] <Fourth embodiment> A UE capability corresponding to at least one function (feature) in the first to third embodiments may be defined. If the UE reports this UE capability, the UE may perform the corresponding function.

[0136] A parameter (higher layer parameter (RRC information element) / MAC CE / DCI) corresponding to this function may be defined. If this parameter is configured / activated / indicated, the UE may perform the corresponding function.

[0137] If the UE reports this UE capability and the parameters corresponding to this function are set / activated / indicated, the UE may perform the corresponding function.

[0138] The UE capability may indicate whether the UE supports this feature.

[0139] The UE capability may indicate whether the UE supports per-TRP / per-UE panel CG configuration (first embodiment).

[0140] The UE capability may indicate whether the UE supports CG PUSCH transmission based on multi-TRP / multi-UE panel (second embodiment). If the UE supports CG PUSCH transmission based on multi-TRP / multi-UE panel, the UE capability may indicate the number of TRP / UE panels (maximum number).

[0141] The UE capability may indicate whether the UE supports a certain mapping pattern (third embodiment).

[0142] According to the above fourth embodiment, the UE can achieve the above functions while maintaining compatibility with existing specifications.

[0143] (Wireless communication systems) A configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination of these methods.

[0144] 7 is a diagram showing an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 may be a system that realizes communication using Long Term Evolution (LTE), 5th generation mobile communication system New Radio (5G NR), or the like, which are specified by the Third Generation Partnership Project (3GPP).

[0145] Furthermore, the wireless communication system 1 may support dual connectivity between a plurality of Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), and the like.

[0146] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (MN) and the NR base station (gNB) is the secondary node (SN). In NE-DC, the NR base station (gNB) is the MN and the LTE (E-UTRA) base station (eNB) is the SN.

[0147] The wireless communication system 1 may support dual connectivity between multiple base stations in the same RAT (for example, dual connectivity in which both the MN and the SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0148] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are arranged in the macrocell C1 and form a small cell C2 that is narrower than the macrocell C1. A user terminal 20 may be located in at least one of the cells. The arrangement and number of each cell and user terminal 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as a base station 10.

[0149] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CC) and dual connectivity (DC).

[0150] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band above 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a frequency band higher than FR2.

[0151] 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).

[0152] The multiple base stations 10 may be connected by wire (e.g., optical fiber conforming to Common Public Radio Interface (CPRI), X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0153] The base station 10 may be connected to the core network 30 directly or via another base station 10. The core network 30 may include at least one of, for example, an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

[0154] The user terminal 20 may be a terminal compatible with at least one of communication methods such as LTE, LTE-A, and 5G.

[0155] In the wireless communication system 1, a wireless access scheme 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.

[0156] The radio access scheme may be called a waveform. In the wireless communication system 1, other radio access schemes (for example, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0157] In the wireless communication system 1, a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc. may be used as a downlink channel.

[0158] In addition, in the wireless communication system 1, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20, an uplink control channel (Physical Uplink Control Channel (PUCCH)), a random access channel (Physical Random Access Channel (PRACH)), etc. may be used as an uplink channel.

[0159] The PDSCH transmits user data, higher layer control information, a System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit a Master Information Block (MIB).

[0160] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information of at least one of the PDSCH and the PUSCH.

[0161] In addition, DCI for scheduling PDSCH may be called DL assignment, DL DCI, etc., and DCI for scheduling PUSCH may be called UL grant, UL DCI, etc. In addition, PDSCH may be replaced with DL data, and PUSCH may be replaced with UL data.

[0162] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources to search for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or multiple search spaces. The UE may monitor a CORESET associated with a certain search space based on the search space configuration.

[0163] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be called a search space set. Note that the terms "search space," "search space set," "search space setting," "search space set setting," "CORESET," and "CORESET setting" in the present disclosure may be read as interchangeable terms.

[0164] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), delivery acknowledgement information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and a scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0165] In the present disclosure, a downlink, an uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning of the channels.

[0166] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, as the DL-RS, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted.

[0167] The synchronization signal may be, for example, at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). A signal block including the SS (PSS, SSS) and the PBCH (and the DMRS for the PBCH) may be called an SS / PBCH block, an SS Block (SSB), or the like. In addition, the SS, SSB, and the like may also be called a reference signal.

[0168] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), etc. may be transmitted as an uplink reference signal (UL-RS). Note that the DMRS may be called a user equipment specific reference signal (UE-specific reference signal).

The user terminal 20 includes a control unit 210, a transceiver unit 220, and a transceiver antenna 230. Note that the user terminal 20 may include one or more of each of the control unit 210, the transceiver unit 220, and the transceiver antenna 230.

[0188] In this example, the functional blocks of the characteristic parts of the present embodiment are mainly shown, and the user terminal 20 may be assumed to have other functional blocks necessary for wireless communication. Some of the processes of each unit described below may be omitted.

The plurality of values ​​may be associated with one of a plurality of consecutive time periods, a plurality of transmission occasions (e.g., PUSCH occasions, PUSCH repetitions) within the period, and a plurality of transmission occasions across the plurality of consecutive time periods. The length of each of the plurality of consecutive time periods may have the period (third embodiment).

[0208] (Hardware configuration) The block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. The method of realizing each functional block is not particularly limited. That is, each functional block may be realized by using one device that is physically or logically combined, or may be realized by using two or more devices that are physically or logically separated and directly or indirectly connected (for example, by wire, wirelessly, etc.). The functional blocks may be realized by combining the one device or the multiple devices with software.

[0209] Here, the functions include, but are not limited to, judgment, determination, judgment, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, resolution, selection, selection, establishment, comparison, assumption, expectation, deeming, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assignment. For example, a functional block (component) that performs the function of transmission may be called a transmitting unit, a transmitter, and the like. In either case, as described above, the method of realization is not particularly limited.

[0210] For example, a base station, a user terminal, etc. in an embodiment of the present disclosure may function as a computer that performs processing of the wireless communication method of the present disclosure. Fig. 10 is a diagram showing an example of a hardware configuration of a base station and a user terminal according to an embodiment. The above-mentioned base station 10 and user terminal 20 may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0211] In this disclosure, the terms "apparatus," "circuit," "device," "section," "unit," and the like can be read interchangeably. The hardware configurations of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the drawings, or may be configured to exclude some of the devices.

[0212] For example, although only one processor 1001 is shown, there may be multiple processors. Also, the processes may be performed by one processor, or the processes may be performed by two or more processors simultaneously, sequentially, or in other manners. Also, the processor 1001 may be implemented by one or more chips.

[0213] Each function in the base station 10 and the user terminal 20 is realized, for example, by loading a specific software (program) onto hardware such as a processor 1001 and a memory 1002, so that the processor 1001 performs calculations, controls communications via a communication device 1004, and controls at least one of reading and writing of data in the memory 1002 and the storage 1003.

[0214] The processor 1001, for example, operates an operating system to control the entire computer. The processor 1001 may be configured with a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. For example, at least a part of the above-mentioned control unit 110 (210), transmission / reception unit 120 (220), etc. may be realized by the processor 1001.

[0215] Moreover, the processor 1001 reads out programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and executes various processes according to the programs. As the programs, programs that cause a computer to execute at least a part of the operations described in the above-mentioned embodiments are used. For example, the control unit 110 (210) may be realized by a control program stored in the memory 1002 and operated by the processor 1001, and the other functional blocks may be realized in a similar manner.

[0216] The memory 1002 is a computer-readable recording medium, and may be configured by at least one of, for example, a Read Only Memory (ROM), an Erasable Programmable ROM (EPROM), an Electrically EPROM (EEPROM), a Random Access Memory (RAM), and other suitable storage media. The memory 1002 may be called a register, a cache, a main memory (primary storage device), and the like. The memory 1002 can store a program (program code), a software module, and the like that is executable to implement a wireless communication method according to an embodiment of the present disclosure.

[0217] Storage 1003 is a computer-readable recording medium and may be constituted by at least one of, for example, a flexible disk, a floppy disk, a magneto-optical disk (e.g., a compact disk (e.g., a Compact Disc ROM (CD-ROM)), a digital versatile disk, a Blu-ray disk), a removable disk, a hard disk drive, a smart card, a flash memory device (e.g., a card, stick, key drive), a magnetic stripe, a database, a server, or other suitable storage medium. Storage 1003 may also be referred to as an auxiliary storage device.

[0218] The communication device 1004 is hardware (transmission / reception device) for performing communication between computers via at least one of a wired network and a wireless network, and is also called, for example, a network device, a network controller, a network card, a communication module, etc. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., in order to realize at least one of Frequency Division Duplex (FDD) and Time Division Duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0219] The input device 1005 is an input device (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that accepts input from the outside. The output device 1006 is an output device (e.g., a display, a speaker, a Light Emitting Diode (LED) lamp, etc.) that performs output to the outside. The input device 1005 and the output device 1006 may be integrated into one device (e.g., a touch panel).

[0220] In addition, each device such as the processor 1001 and the memory 1002 is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0221] Furthermore, the base station 10 and the user terminal 20 may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), a field programmable gate array (FPGA), etc., and some or all of the functional blocks may be realized using the hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0222] (Modification) In addition, the terms explained in this disclosure and the terms necessary for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be read as mutually interchangeable. A signal may also be a message. A reference signal may also be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applied standard. A component carrier (CC) may also be called a cell, a frequency carrier, a carrier frequency, etc.

[0223] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0224] Here, the numerology may be a communication parameter applied to at least one of the transmission and reception of a signal or channel, and may indicate at least one of, for example, a subcarrier spacing (SCS), a bandwidth, a symbol length, a cyclic prefix length, a transmission time interval (TTI), a number of symbols per TTI, a radio frame structure, a specific filtering process performed by a transceiver in the frequency domain, and a specific windowing process performed by a transceiver in the time domain.

[0225] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol, etc.) in the time domain. A slot may also be a time unit based on numerology.

[0226] A slot may include multiple minislots. Each minislot may be composed of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may be composed of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0227] A radio frame, a subframe, a slot, a minislot, and a symbol each represent a time unit for transmitting a signal. A different name may be used for the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be read as interchangeable with each other.

[0228] For example, one subframe may be called a TTI, multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in the existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc., instead of a subframe.

[0229] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0230] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) in which a transport block, a code block, a code word, etc. are actually mapped may be shorter than the TTI.

[0231] In addition, when one slot or one minislot is called TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit of scheduling. Also, the number of slots (minislots) constituting the minimum time unit of scheduling may be controlled.

[0232] A TTI having a time length of 1 ms may be called a normal TTI (TTI in 3GPP Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a slot, etc.

[0233] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length exceeding 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and equal to or greater than 1 ms.

[0234] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of the numerology, and may be, for example, 12. The number of subcarriers included in an RB may be determined based on the numerology.

[0235] In addition, an RB may include one or more symbols in the time domain, and may have a length of one slot, one minislot, one subframe, or one TTI. Each of one TTI, one subframe, etc. may be composed of one or more resource blocks.

[0236] In addition, one or more RBs may be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0237] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0238] A Bandwidth Part (BWP), which may also be referred to as a fractional bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a numerology on a carrier, where the common RBs may be identified by the index of the RBs relative to a common reference point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0239] The BWP may include a UL BWP (a BWP for UL) and a DL BWP (a BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0240] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given channel / signal outside the active BWP. Note that the terms "cell", "carrier", etc. in this disclosure may be replaced with "BWP".

[0241] The above-mentioned structures of radio frames, subframes, slots, minislots, and symbols are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, and other configurations can be changed in various ways.

[0242] In addition, the information, parameters, etc. described in the present disclosure may be represented using absolute values, may be represented using relative values ​​from a predetermined value, or may be represented using other corresponding information.

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

For example, the data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0245] Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via a plurality of network nodes.

[0246] Input and output information, signals, etc. may be stored in a specific location (e.g., memory) or may be managed using a management table. Input and output information, signals, etc. may be overwritten, updated, or added to. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

[0247] The notification of information is not limited to the aspects / embodiments described in the present disclosure, and may be performed using other methods. For example, the notification of information in the present disclosure may be performed by physical layer signaling (e.g., Downlink Control Information (DCI) and Uplink Control Information (UCI)), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB) and System Information Block (SIB)), Medium Access Control (MAC) signaling), other signals, or a combination thereof.

[0248] The physical layer signaling may be called Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. The RRC signaling may be called an RRC message, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc. The MAC signaling may be notified, for example, by using a MAC Control Element (CE).

[0249] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0250] The determination may be made based on a value represented by a single bit (0 or 1), a Boolean value represented as true or false, or by comparing numerical values ​​(e.g., with a predetermined value).

[0252] Additionally, software, instructions, information, etc. may be transmitted or received over a transmission medium. For example, if the software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL)), and / or wireless technologies (such as infrared, microwave, etc.), then these wired and / or wireless technologies are included within the definition of transmission media.

For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.

[0260] Furthermore, the base station in the present disclosure may be read as a user terminal. For example, each aspect / embodiment of the present disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between a plurality of user terminals (which may be called, for example, Device-to-Device (D2D) or Vehicle-to-Everything (V2X)).
