DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (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).

[0012] 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.

[0013] 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.

[0014] 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).

[0015] 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).

[0016] 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.

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

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

[0019] 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.

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

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

[0022] 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).

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

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

[0025] A QCL type A RS is always configured for PDCCH and PDSCH, and a QCL type D RS may be configured additionally. Since it is difficult to estimate Doppler shift, delay, etc. by one-shot reception of DMRS, a QCL type A RS is used to improve channel estimation accuracy. A QCL type D RS is used to determine the receiving beam when receiving DMRS.

[0026] For example, TRS1-1, 1-2, 1-3, and 1-4 are transmitted, and TRS1-1 is notified as QCL type C / D RS by the TCI state of the PDSCH. By notifying the TCI state, the UE can use information obtained from past periodic reception / measurement results of TRS1-1 for reception / channel estimation of DMRS for PDSCH. In this case, the QCL source of the PDSCH is TRS1-1, and the QCL target is the DMRS for PDSCH.

[0027] (CSI) In NR, a UE measures a channel state using a reference signal (or a resource for the reference signal) and feeds back (reports) channel state information (CSI) to a network (e.g., a base station).

[0028] The UE may measure the channel state using at least one of a Channel State Information Reference Signal (CSI-RS), a Synchronization Signal / Physical Broadcast Channel (SS / PBCH) block, a Synchronization Signal (SS), a DeModulation Reference Signal (DMRS), etc.

[0029] The CSI-RS resources may include at least one of a Non Zero Power (NZP) CSI-RS resource, a Zero Power (ZP) CSI-RS resource, and a CSI Interference Measurement (CSI-IM) resource.

[0030] The resource for measuring the signal component for CSI may be referred to as a Signal Measurement Resource (SMR) or a Channel Measurement Resource (CMR). The SMR (CMR) may include, for example, NZP CSI-RS resources, SSB, etc. for channel measurement.

[0031] A resource for measuring an interference component for CSI may be referred to as an interference measurement resource (IMR). The IMR may include, for example, at least one of a NZP CSI-RS resource, an SSB, a ZP CSI-RS resource, and a CSI-IM resource for interference measurement.

[0032] An SS / PBCH block is a block that includes a synchronization signal (e.g., a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS)) and a PBCH (and corresponding DMRS), and may also be referred to as an SS block (SSB), etc.

[0033] In addition, the CSI may include at least one of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), a SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), L1-RSRP (Layer 1 Reference Signal Received Power), L1-RSRQ (Reference Signal Received Quality), L1-SINR (Signal to Interference plus Noise Ratio), and L1-SNR (Signal to Noise Ratio).

[0034] The CSI may have multiple parts. CSI Part 1 may include information with a relatively small number of bits (e.g., RI). CSI Part 2 may include information with a relatively large number of bits (e.g., CQI), such as information determined based on CSI Part 1.

[0035] Furthermore, CSI may be classified into several CSI types. The type and size of information to be reported may differ depending on the CSI type. For example, a CSI type set for communication using a single beam (also called type I CSI, CSI for single beam, etc.) and a CSI type set for communication using multiple beams (also called type II CSI, CSI for multiple beams, etc.) may be specified. The use of the CSI types is not limited to this.

[0036] Methods of CSI feedback under consideration include periodic CSI (P-CSI) reporting, aperiodic CSI (A-CSI) reporting, and semi-persistent CSI (SP-CSI) reporting.

[0037] The UE may be notified of the CSI measurement configuration information using higher layer signaling, physical layer signaling, or a combination thereof.

[0038] In the present disclosure, higher layer signaling may be, for example, any one or a combination of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, and the like.

[0039] The MAC signaling may be, for example, a MAC Control Element (MAC CE), a MAC Protocol Data Unit (PDU), etc. The broadcast information may be, for example, a Master Information Block (MIB), a System Information Block (SIB), Remaining Minimum System Information (RMSI), Other System Information (OSI), etc.

[0040] The physical layer signaling may be, for example, Downlink Control Information (DCI).

[0041] The CSI measurement configuration information may be configured, for example, using the RRC information element "CSI-MeasConfig". The CSI measurement configuration information may include CSI resource configuration information (RRC information element "CSI-ResourceConfig"), CSI reporting configuration information (RRC information element "CSI-ReportConfig"), etc. The CSI resource configuration information relates to resources for CSI measurement, and the CSI reporting configuration information relates to how the UE performs CSI reporting.

[0042] 1A and 1B are diagrams showing an example of an RRC information element related to a CSI reporting configuration and a CSI resource configuration. In this example, an excerpt of fields (which may be called parameters) included in the information element is shown. FIG. 1A and 1B are described using ASN.1 (Abstract Syntax Notation One) notation. Note that drawings related to other RRC information elements (or RRC parameters) in the present disclosure are also described using the same notation.

[0043] As shown in FIG. 1A, the CSI reporting configuration information ("CSI-ReportConfig") includes resource information for channel measurement ("resourcesForChannelMeasurement"). The CSI reporting configuration information may also include resource information for interference measurement (e.g., NZP CSI-RS resource information for interference measurement ("nzp-CSI-RS-ResourcesForInterference"), CSI-IM resource information for interference measurement ("csi-IM-ResourcesForInterference"), etc.). These pieces of resource information correspond to the ID (Identifier) ​​of the CSI resource configuration information ("CSI-ResourceConfigId").

[0044] Note that the IDs of the CSI resource configuration information corresponding to each piece of resource information (which may be referred to as CSI resource configuration IDs) may be one or more of the same value, or may each have a different value.

[0045] 1B , the CSI resource configuration information ("CSI-ResourceConfig") may include a CSI resource configuration information ID, CSI-RS resource set list information ("csi-RS-ResourceSetList"), a resource type ("resourceType"), etc. The CSI-RS resource set list may include at least one of NZP CSI-RS and SSB information for measurement ("nzp-CSI-RS-SSB") and CSI-IM resource set list information ("csi-IM-ResourceSetList").

[0046] The resource type indicates the time domain behavior of this resource configuration, and can be set to "aperiodic", "semi-persistent", or "periodic". For example, the corresponding CSI-RS may be called A-CSI-RS, SP-CSI-RS, or P-CSI-RS.

[0047] The channel measurement resources may be used to calculate, for example, CQI, PMI, L1-RSRP, etc. The interference measurement resources may be used to calculate L1-SINR, L1-SNR, L1-RSRQ, and other indices related to interference.

[0048] If the interference measurement is performed on CSI-IM, each CSI-RS for channel measurement may be associated with a CSI-IM resource in terms of resources based on the order of the CSI-RS resources and the CSI-IM resources in the corresponding resource set.

[0049] The "nzp-CSI-RS-SSB" may include NZP CSI-RS resource set list information ("nzp-CSI-RS-ResourceSetList") and SSB resource set list information for CSI measurements ("csi-SSB-ResourceSetList"), which may correspond to one or more NZP CSI-RS resource set IDs ("NZP-CSI-RS-ResourceSetId") and CSI-SSB resource set IDs ("CSI-SSB-ResourceSetId"), respectively, and may be used to identify resources to be measured.

[0050] 2A and 2B are diagrams illustrating example RRC information elements for NZP CSI-RS resource sets and CSI-SSB resource sets.

[0051] As shown in FIG. 2A, the NZP CSI-RS resource set information ("NZP-CSI-RS-ResourceSet") includes an NZP CSI-RS resource set ID and one or more NZP CSI-RS resource IDs ("NZP-CSI-RS-ResourceIds").

[0052] The NZP CSI-RS resource information ("NZP-CSI-RS-Resource") may include an NZP CSI-RS resource ID and an ID ("TCI-stateId") of a Transmission Configuration Indication state (TCI state). TCI states are described below.

[0053] As shown in Figure 2B, the CSI-SSB resource set information ("CSI-SSB-ResourceSet") includes a CSI-SSB resource set ID and one or more SSB index information ("SSB-Index"), which may be an integer between 0 and 63, and may be used to identify an SSB within an SS burst.

[0054] FIG. 3 is a diagram showing an example of an RRC information element related to the TCI status.

[0055] The TCI state is information about Quasi-Co-Location (QCL) of a channel or a signal, and may also be called spatial reception parameters, spatial relation info, etc. The TCI state may be configured or specified to the UE for each channel or signal.

[0056] As shown in Fig. 3, the TCI state information ("TCI-State") may include a TCI state ID and one or more pieces of QCL information ("QCL-Info"). The QCL information may include at least one of information on a reference signal of a QCL source (RS related information ("referenceSignal")) and information indicating a QCL type (QCL type information ("qcl-Type")). The RS related information may include information such as an index of the RS (e.g., NZP CSI-RS resource ID, SSB index), an index of a serving cell, an index of a Bandwidth Part (BWP) where the RS is located, etc.

[0057] The UE may control receiving processing (e.g., at least one of receiving, demapping, demodulation, decoding, receive beam determination, etc.), transmitting processing (e.g., at least one of transmitting, mapping, modulation, encoding, transmit beam determination, etc.), etc. for at least one of a signal and a channel (referred to as a signal / channel) based on a TCI state corresponding to a TCI state ID associated with the signal / channel.

[0058] In the present disclosure, "A / B" may mean "at least one of A and B."

[0059] As shown in Figure 2A, for the P-CSI-RS, the associated TCI state may be configured by the RRC, whereas for the P-CSI-RS, SP-CSI-RS and A-CSI-RS, the associated TCI state may be determined based on higher layer signaling, physical layer signaling or a combination thereof.

[0060] (Beam Management) In Rel.15 NR, a method of Beam Management (BM) has been considered. In the beam management, beam selection is considered to be performed based on the L1-RSRP reported by the UE. Changing (switching) the beam of a certain signal / channel may correspond to changing at least one of the TCI state and QCL assumption of the signal / channel.

[0061] The UE may report (transmit) the measurement result for beam management using an uplink control channel (Physical Uplink Control Channel (PUCCH)) or an uplink shared channel (Physical Uplink Shared Channel (PUSCH)). The measurement result may be, for example, CSI including at least one of L1-RSRP, L1-RSRQ, L1-SINR, and L1-SNR.

[0062] Measurement results (e.g., CSI) reported for beam management may be referred to as beam measurement, beam measurement report, beam report, beam report CSI, etc.

[0063] The CSI measurement for the beam report may include interference measurement. The UE may measure channel quality, interference, etc. using resources for CSI measurement to derive a beam report.

[0064] The beam report may include at least one of a channel quality measurement and an interference measurement. The channel quality measurement may include, for example, L1-RSRP. The interference measurement may include, for example, L1-SINR, L1-SNR, L1-RSRQ, or other interference-related metric (e.g., any metric other than L1-RSRP).

[0065] The CSI reporting configuration information considering the current NR beam management will be described with reference to Fig. 4. Fig. 4 is an excerpt of the RRC information element "CSI-ReportConfig". Fig. 4 excerpts another part of the same CSI reporting configuration information (CSI-ReportConfig) as Fig. 1A.

[0066] The CSI reporting configuration information may include a "report quantity" (which may be represented by the RRC parameter "reportQuantity"), which is information on parameters to be reported in one report instance (e.g., one CSI). The report quantity is defined by an ASN.1 object type called "choice". For this reason, one of the parameters (cri-RSRP, ssb-Index-RSRP, etc.) defined as the report quantity is set.

[0067] A UE in which an upper layer parameter included in the CSI reporting configuration information (e.g., the RRC parameter "groupBasedBeamReporting" for group-based beam reporting) is set to disabled may include in a beam report (one report instance) for each report setting, a different number of beam measurement resource IDs (e.g., SSBRI, CRI) for each upper layer parameter included in the CSI reporting configuration information (e.g., the RRC parameter "nrofReportedRS" indicating the number of RSs to be reported) and measurement results (e.g., L1-RSRP) corresponding to each ID.

[0068] A UE with groupBasedBeamReporting enabled may include two different beam measurement resource IDs and two measurement results (e.g., L1-RSRP) corresponding to each ID in a beam report for each report configuration. In other words, a UE with groupBasedBeamReporting enabled divides DL-RS (e.g., CSI-RS) into two groups and reports the ID and measurement value for the top RS in each group. The two beam measurement resources (CSI-RS resource, SSB resource) may be received simultaneously by the UE using one spatial domain receive filter or multiple simultaneous spatial domain receive filters.

[0069] Furthermore, the NZP CSI-RS resource set information shown in Fig. 2A may include information regarding repetition of resources in the resource set. The information regarding the repetition may indicate, for example, 'on' or 'off'. Note that 'on' may be expressed as 'enabled' or 'valid', and 'off' may be expressed as 'disabled' or 'invalid'.

[0070] For example, for a resource set with repetition set 'on', the UE may assume that the resources in that resource set are transmitted using the same downlink spatial domain transmission filter, in which case the UE may assume that the resources in that resource set are transmitted using the same beam (e.g., from the same base station using the same beam).

[0071] For a resource set with repetition set to 'off', the UE may not (or may not) assume that resources in the resource set are transmitted using the same downlink spatial domain transmit filter. In this case, the UE may assume that resources in the resource set are not transmitted using the same beam (transmitted using different beams). In other words, for a resource set with repetition set to 'off', the UE may assume that the base station is performing beam sweeping.

[0072] In Rel.15 NR, the reporting amount of cri-RSRP and ssb-Index-RSRP is related to beam management. A UE with cri-RSRP set as the reporting amount reports CRI and L1-RSRP corresponding to the CRI. A UE with ssb-Index-RSRP set as the reporting amount reports SSBRI and L1-RSRP corresponding to the SSBRI.

[0073] 5 is a diagram showing an example of a CSI report in Rel.15 NR, showing a mapping order of CSI fields included in one CSI report (n-th CSI report #n) for CSI / RSRP or SSBRI / RSRP reporting, as specified in Table 6.3.1.1.2-8 of 3GPP TS 38.212 V15.7.0.

[0074] 5 may include one or more pairs of CRI / SSBRI and RSRP, the number of which may be configured by a higher layer parameter (e.g., the RRC parameter "nrofReportedRS") indicating the number of reference signal resources to be reported.

[0075] For L1-RSRP reporting, if nrofReportedRS is set to 1 (value 'n1'), then the CSI report includes RSRP#1, a field of a predefined number of bits (e.g., m bits) indicating the L1-RSRP with the highest measurement value. In Rel.15 NR, m=7.

[0076] For L1-RSRP reporting, when nrofReportedRS is set to be greater than 1 or when groupBasedBeamReporting is set to be enabled, the UE uses differential L1-RSRP-based reporting. Specifically, the UE includes RSRP#1 indicating the L1-RSRP of the largest measurement value and differential (Differential) RSRP#k calculated for the kth (k=2, 3, 4 in FIG. 5) largest L1-RSRP with reference to the largest measurement value (e.g., as a difference from the measurement value) in the same CSI report (reporting instance). Here, differential RSRP#k may be a field of fewer bits (e.g., n bits) than the above-mentioned predetermined number. In Rel. 15 NR, n=4.

[0077] In addition, when groupBasedBeamReporting is set to be enabled, the UE includes RSRP#1 and differential RSRP#2 in the same CSI report.

[0078] CRI / SSBRI#k in FIG. 5 is a field indicating the CRI / SSBRI corresponding to RSRP#k or differential RSRP#k (included when reporting RSRP#k or differential RSRP#k).

[0079] In addition, in NR after Rel.16, nrofReportedRS may be a value equal to or greater than 4. A CSI report may include a set of CRI / SSBRI and RSRP equal to or greater than 4. The above m, n, etc. are not limited to 7 and 4, respectively.

[0080] In addition, in NR after Rel.16, L1-SINR reporting may be performed. The above-mentioned L1-RSRP report may be applied with SINR substituted for RSRP. In this case, the setting / parameter for SINR may be different from the setting / parameter for RSRP. For example, the above nrofReportedRS may be replaced with nrofReportedRSForSINR, which indicates the number of reference signal resources to be reported for SINR.

[0081] (unified / common TCI framework) According to the unified TCI framework, UL and DL channels can 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 (common TCI state) 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.

[0082] 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.

[0083] The UE may assume the same TCI state for UL and DL (joint TCI state, joint TCI pool, joint common TCI pool). The UE may assume different TCI states for UL and DL respectively (separate TCI state, separate TCI pool, UL separate TCI pool and DL separate TCI pool, separate common TCI pool, UL common TCI pool and DL common TCI pool).

[0084] 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).

[0085] A common beam / unified TCI state may be indicated from the same TCI pool (joint common TCI pool, joint TCI pool, set) for both UL and DL 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.

[0086] The TCI pool (set) may be multiple TCI states configured by RRC parameters, or multiple TCI states (active TCI states, active TCI pools, sets) activated by the MAC CE among multiple TCI states configured by RRC parameters. Each TCI state may be a QCL type A / D RS. SSB, CSI-RS, or SRS may be configured as the QCL type A / D RS.

[0087] In the example of FIG. 6A, the RRC parameters (information elements) configure multiple TCI states for both DL and UL. The MAC CE may activate multiple TCI states among the configured multiple TCI states. The DCI may indicate one of the activated multiple TCI states. The DCI may be a UL / DL DCI. The indicated TCI state may apply to at least one (or all) of the UL / DL channels / RS. One DCI may indicate both UL TCI and DL TCI.

[0088] In the example of FIG. 6A, a point may be one TCI state that applies to both the UL and DL, or it may be two TCI states that apply to the UL and DL, respectively.

[0089] At least one of the multiple TCI states configured by the RRC parameters and the multiple TCI states activated by the MAC CE may be referred to as a TCI pool (common TCI pool, joint TCI pool, TCI state pool). The multiple TCI states activated by the MAC CE may be referred to as an active TCI pool (active common TCI pool).

[0090] In the present disclosure, higher layer parameters (RRC parameters) for setting multiple TCI states may be referred to as configuration information for setting multiple TCI states, or simply as "configuration information." Also, in the present disclosure, being instructed to set one of multiple TCI states using DCI may mean receiving indication information instructing one of multiple TCI states included in DCI, or may simply mean receiving "instruction information."

[0091] In the example of Figure 6B, the RRC parameters configure multiple TCI states (joint common TCI pools) for both DL and UL. The MAC CE may activate multiple TCI states (active TCI pools) out of the configured multiple TCI states. Separate active TCI pools for each of the UL and DL may be configured / activated.

[0092] The DL DCI or new DCI format may select (indicate) one or more (e.g., one) TCI states. The selected TCI state may be applied to one or more (or all) DL channels / RS. The DL channels may be PDCCH / PDSCH / CSI-RS. The UE may determine the TCI state of each DL channel / RS using the TCI state behavior (TCI framework) of Rel. 16. The UL DCI or new DCI format may select (indicate) one or more (e.g., one) TCI states. The selected TCI state may be applied to one or more (or all) UL channels / RS. The UL channels may be PUSCH / SRS / PUCCH. Thus, different DCIs may indicate UL TCI and DL DCI separately.

[0093] The existing DCI format 1_2 / 1_2 may be used to indicate the common TCI status.

[0094] The common TCI framework may have separate TCI states for DL ​​and UL.

[0095] The common TCI framework may have separate TCI states for DL ​​and UL. It is not preferred to use DCI format 1_1 / 1_2 to indicate common TCI states for UL only.

[0096] (UL panel selection) In future wireless communication systems (e.g., Rel.17 and beyond), Rel.17 TCI state updates (e.g., MAC CE+DCI / MAC CE activate TCI state) are being considered to perform fast UL panel selection. When multiple panels are applied, each panel may support different configurations (e.g., different port numbers / different beams). For example, UE panels may have the same or different antenna port numbers, beam numbers, or equivalent isotopically radiated power (EIRP).

[0097] It is also assumed that a panel (or panel entity) corresponds to one or more reference signal resources (hereinafter also referred to as RS resources). In case of CSI / beam reporting, the RS resource / RS resource set (hereinafter simply referred to as RS resources) is the RS related to the measurement / report. In case of beam indication, the RS resource corresponds to the source RS of the UL transmit spatial filter information (e.g., UL TX spatial filter information).

[0098] It is assumed that the panel entity (or panel ID) corresponding to one RS resource may be different, and the problem arises as to how to achieve a common understanding between the UE and the base station regarding the panel entity corresponding to the RS resource (or TCI state).

[0099] In other words, considering cases where parameters such as the number of ports differ depending on the UE panel, it is necessary to properly reach a common understanding between the base station and UE regarding the panel that corresponds to the RS resources for CSI / beam reporting, and to configure the base station to make appropriate settings based on the report from the UE.

[0100] For example, in the CSI / beam report, whether or not it is supported that the CRI / SSBRI supports multiple panels becomes an issue. If the CSI / beam report supports that the CRI / SSBRI supports multiple panels and an RS that supports multiple panels is used as a source RS of TCI for DL ​​QCL or UL spatial filter, how to set / indicate the panel information of TCI (e.g., the correspondence between TCI state and panel) becomes an issue.

[0101] The present inventors therefore studied the correspondence between RS resources and panels, or a method of setting / indicating panel information corresponding to TCI, and came up with the idea of ​​the present invention.

[0125] (First aspect) In the first aspect, a case will be described in which control is performed so as not to report a plurality of measurement results (eg, L1-RSRP / L1-SINR) corresponding to a plurality of panels for a measurement signal resource (eg, CRI / SSBRI).

[0126] When a UE reports a measurement result (e.g., a CSI / beam report), the UE may transmit information about a signal resource for measurement and information about a panel (or an antenna group, an RS group, or a TCI state group). The information about a panel may be a panel ID (or an antenna group ID, an RS group ID, or a TCI state group ID).

[0127] The UE may control not to report multiple measurement results corresponding to multiple panels for one CRI / SSBRI in a certain CSI / beam report. That is, in a certain CSI report, a single CRI / SSBRI (and corresponding measurement result) may correspond to one panel ID.

[0128] In this case, for example, control may be performed so that multiple panels are not set for one measurement signal (for example, CSI-RS / SSB). Alternatively, a different measurement signal may be associated with each panel.

[0129] If the information about the panel (panel ID) is set to explicit, or if the UE explicitly reports the panel ID, the UE may be configured not to support (or allow) reporting multiple measurement results corresponding to multiple panel IDs for the same CRI / SSBRI (see Figure 7A).

[0130] FIG. 7A shows a case where the same RS corresponds to different panels in a certain measurement result report (here, CSI report #n). Here, CRI / SSBRI#1 (='00') and CRI / SSBRI#2 (='00') mean the same RS, and the same RS corresponds to different panel IDs (here, CRI / SSBRI#1 corresponds to panel ID#1, and CRI / SSBRI#2 corresponds to panel ID#2). The UE may be controlled not to perform such CSI report.

[0131] FIG. 7B shows a case where the same RS does not correspond to different panels (a single RS corresponds to each panel) in a report of a certain measurement result (here, CSI report #n). Here, CRI / SSBRI#1 (='00') and CRI / SSBRI#2 (='01') mean different RSs, and the same RS does not correspond to different panel IDs. The UE may be allowed to report such CSI.

[0132] When the information about the panel (panel ID) is set to implicit, or when the UE reports the panel ID implicitly, the UE may be configured not to support (or allow) reporting the same CRI / SSBRI for multiple groups (see FIG. 8A). As a method in which the panel ID is set implicitly or the UE reports the panel ID implicitly, each panel ID may be associated with a group including one or more CRI / SSBRI and measurement results.

[0133] 8A shows a case where CRI#1-1 and CRI#1-2 (+RSRP / SINR#1-1 and RSRP / SINR#1-2) correspond to group #1, and CRI#2-2 and CRI#2-3 (+RSRP / SINR#2-2 and RSRP / SINR#2-3) correspond to group #2. Furthermore, group #1 corresponds to panel ID#1, and group #2 corresponds to panel ID#2.

[0134] In Fig. 8A, CRI#1-1 (='00') and CRI#2-2 (='00') are the same RS, and the same RS corresponds to different groups / panel IDs (here, CRI#1-1 corresponds to group#1 / panel ID#1, and CRI#2-2 corresponds to group#2 / panel ID#2). The UE may perform control not to report such CSI.

[0135] FIG. 8B shows a case where the same RS does not correspond to different groups (a single RS corresponds to each group) in a report of a certain measurement result (here, CSI report #n). Here, CRI#1-1 (='00') and CRI#2-2 (='01') are different RSs, and the same RS does not correspond to different groups (panels). The UE may be allowed to report such CSI.

[0136] In this way, by configuring a CSI report so that multiple measurement results corresponding to multiple panels are not reported for the same CRI / SSBRI, it becomes possible to directly infer the DL / UL panel information (or the TCI state corresponding to the panel) from the source RS of the TCI state (or the source RS corresponding to the TCI state).

[0137] For example, since the base station can know the panel ID and the TCI state from the CSI / beam report from the UE, the base station may be configured not to explicitly associate the TCI state with the panel ID.

[0138] (Second aspect) In the second aspect, a case is described in which in reporting a certain measurement result (e.g., CSI / beam report), reporting of multiple measurement results (e.g., L1-RSRP / L1-SINR) corresponding to multiple panels is permitted for a measurement signal resource (e.g., CRI / SSBRI).

[0139] In such a case, the panel information (or the association between the panel and the TCI state) may be set / indicated using at least one of the following options 1 to 3.

[0140] In addition, the RRC / MAC CE / DCI shown in the second aspect may be applied when controlling not to report multiple measurement results (e.g., L1-RSRP / L1-SINR) corresponding to multiple panels for a measurement signal resource (e.g., CRI / SSBRI).

[0141] <Option 1> The DL / UL panel information (or the association between the panel and the TCI state) may be determined / configured / indicated at the time of RRC configuration of the TCI state (e.g., RRC configuration of TCI).

[0142] Option 1-1 The panel ID may be included in configuration information of the TCI state (for example, TCI state configuration) (see FIG. 9A). FIG. 9A illustrates a case in which the panel ID (or the TCI state group ID) is included in higher layer parameters related to the TCI state. The UE may determine the association between the panel ID and the TCI state based on the higher layer parameters related to the TCI state notified from the base station.

[0143] Option 1-2 The TCI state group may be set by higher layer parameters, and a panel ID / TCI state group ID association may be set for each TCI state group (see FIG. 9B). FIG. 9B shows a case where the higher layer parameters related to the TCI state include a correspondence between the TCI state group and the panel ID. The UE may determine the association between the panel ID and the TCI state group based on the higher layer parameters related to the TCI state notified from the base station.

[0144] Note that multiple TCI groups with different panel IDs / group IDs may be configured not to include the same TCI state. In this case, the UE does not need to expect / assume that multiple TCI groups with different panel IDs / group IDs include the same TCI state.

[0145] <Option 2> The DL / UL panel information (or the association between the panel and the TCI state) may be determined / set / indicated by the MAC CE upon activation of the TCI state.

[0146] Option 2-1 The MAC CE used for TCI state activation may include a field corresponding to a panel ID (or a TCI state group ID) and may support indicating activation of TCI states corresponding to multiple panels (e.g., panel #1 and panel #2) (see Figures 10A and 10B).

[0147] 10A and 10B show an example of a MAC CE having a field for reporting a panel ID and a field corresponding to a TCI state ID, which may include at least one of a field for a serving cell ID, a field for a BWP ID, and a field for a control resource set pool index ID.

[0148] The field corresponding to the TCI state ID may be configured with one bit for each TCI state ID, with '1' being set for the TCI state to be activated.

[0149] FIG. 10A shows the case where a TCI state (e.g., a TCI state to be activated) corresponding to a first panel (e.g., panel ID #0) is indicated, and FIG. 10B shows the case where a TCI state (e.g., a TCI state to be activated) corresponding to a second panel (e.g., panel ID #1) is indicated.

[0150] Here, the case is shown in which TCI states #7, #10, and #12 are activated in panel ID #0, and TCI states #0, #2, #4, #6, and #9 are activated in panel ID #1.

[0151] A specific value (e.g., 8) may be set as the maximum number of TCI states that may be activated in multiple panels (here, panel #0 and panel #1), or the maximum number of TCI states that may be activated in multiple panels (here, panel #0 and panel #1) may be set by higher layer signaling.

[0152] 10A and 10B, the number of TCI states activated in each panel may be set differently, which allows flexibility in setting the TCI states activated for each panel.

[0153] Alternatively, the number of TCI states activated in each panel may be controlled to be the same.

[0154] Also, a maximum number of TCI states that may be activated per panel may be defined, for example the number of TCI states that may be activated in each panel may be set to the same number (e.g., 4).

[0155] The activated TCI states may be associated with code points in a predefined field of the DCI (e.g., a field used to specify the TCI state). For example, a code point in a predefined field used to indicate the TCI state may be mapped to the activated TCI states in multiple (or all) panels. The mapping between the activated TCI state ID and the code points may be controlled based on predefined rules.

[0156] [Rule 1] For a code point in a predetermined field of DCI, the activated TCI states (Ti) may be mapped to the order of TCI state indexes (see FIG. 11A). In this case, the number of TCI states activated for each panel ID may be controlled by a predetermined rule (e.g., even for each panel) or by a setting by a higher layer. Alternatively, the number of TCI states activated for each panel ID may be set by the base station (e.g., only the maximum number of TCI states to be activated is defined, and the base station may flexibly set the number by the MAC CE).

[0157] [Rule 2] For code points in a given field of the DCI, the TCI states may be mapped first in the order of the panel ID, and then in the order of the index among the activated TCI states within the panel (see FIG. 11B). For example, for code points in a given field of the DCI, the TCI states activated for a particular panel ID (e.g., a panel ID with a lower index) may be mapped to the order of the TCI state index, and then the TCI states activated for other panel IDs may be mapped to the order of the TCI state index.

[0158] The instruction to activate the TCI state of the first panel and the instruction to activate the TCI state of the second panel may be performed separately using different MAC CEs (see FIG. 12). In this case, the UE may determine the mapping between the DCI codepoint and the TCI state based on the MAC CE (first MAC CE) that instructs the activation of the TCI state of the first panel and the MAC CE (second MAC CE) that instructs the activation of the TCI state of the second panel.

[0159] Alternatively, the instruction to activate the TCI state of the first panel and the instruction to activate the TCI state of the second panel may be performed using the same MAC CE (by a common MAC CE) (see FIG. 13). In this case, the TCI state field corresponding to the second panel ID does not always exist, but may be configured to be set / added to the MAC CE when multiple panels (e.g., the second panel) are set.

[0160] [Rule 3] An activated TCI state corresponding to each panel may be indicated from one MAC CE, and the TCI state may be mapped to a code point in a predetermined field of the DCI.

[0161] For example, one MAC CE may instruct activation of up to M (e.g., M=8) TCI states for all panels. The correspondence (or mapping) between the activated TCI states and each panel may be determined based on a predetermined rule. For example, the first M1 of the activated TCI state indexes may correspond to a first panel, and the last M2 of the activated TCI state indexes may correspond to a second panel. M1 and M2 may be the same (half & half) or different. M1 and M2 may be set by a higher layer.

[0162] By configuring the number of TCI states to be activated for each panel to be separately configurable, it is possible to flexibly control the allocation of activated TCI states corresponding to each panel.

[0163] FIG. 14 shows a case where the first M1 of the TCI states instructed to be activated (here, TCI states #0, #2, #4, #6) are mapped to panel #0, and the last M2 of the TCI states (here, TCI states #7, #9, #10, #12) are mapped to panel #1. In this way, by using the fields for each TCI state in common for multiple panels in one MAC CE, it is possible to suppress an increase in MAC CE overhead. Also, the MAC CE shown in FIG. 14 may be configured not to include a field for notifying the panel ID.

[0164] If the number of panels is not configured, or if the number of TCI states to be activated is not configured, the UE may assume that all TCI states indicated for activation correspond to one panel, or the UE may assume that the TCI states indicated for activation correspond to a predetermined number of panels (e.g., two panels).

[0165] Option 2-2 The MAC CE used for activating the TCI state may include a field corresponding to a panel ID (or a TCI state group ID) and may indicate activation of a TCI state corresponding to a single panel (see FIG. 15A). Also, a code point of a predetermined field included in the DCI may be associated with a TCI state corresponding to one panel (e.g., a TCI state activated for one panel by the MAC CE) (see FIG. 15B).

[0166] In Fig. 15B, the TCI states activated for a first panel (e.g., panel #0) are shown to be mapped to the respective code points of a field included in the DCI. That is, all the TCI states activated by the MAC CE (here, TCI states #2, #5, #7, #9, #10, #12, #13, #14) may correspond to the respective code points of a given field of one panel (e.g., panel #0) / DCI.

[0167] The maximum number of activated TCI states may be defined in the specification (e.g., 8) or may be set by higher layer signaling. In this case, the panel to which each code point in the DCI corresponds may be indicated separately. Such indication may be based on other fields in the DCI.

[0168] Option 2-3 The MAC CE used for activating a TCI state may include a field corresponding to a panel ID (or a TCI state group ID) and may support indicating activation of TCI states corresponding to multiple panels (e.g., panel #1 and panel #2) respectively (see Figures 16A-16C). Figures 16A and 16B show the case where the TCI state to be activated is specified using multiple bits, rather than a field corresponding to each TCI state (e.g., a one-bit field) being set.

[0169] 16A shows an example of TCI states to be activated in a first panel (e.g., panel #0). Here, a case is shown in which at least a TCI state corresponding to TRP#1 (e.g., TCI state #0,1='0') and a TCI state corresponding to TRP#2 (e.g., TCI state #0,2='2') are activated. TRP#1 may be replaced with CORESET pool index 0, and TRP#2 may be replaced with CORESET pool index 1.

[0170] 16B shows an example of activated TCI states in a second panel (e.g., panel #1), where at least the TCI state corresponding to TRP#1 (e.g., TCI state #0,1='3') and the TCI state corresponding to TRP#2 (e.g., TCI state #0,2='8') are activated.

[0171] As shown in Fig. 16C, the TCI state activated by the MAC CE (for example, the TCI state activated for each panel) may be mapped to each code point in a predetermined field included in the DCI. As a mapping method between each code point and the TCI state corresponding to each panel, the code points may be mapped first in the order of the panel ID, and then in the order of the index i of the activated TCI states (TCI IDi,j) in the panel. Note that the mapping rule is not limited to this, and at least one of the above rules 1 to 3 may be applied.

[0172] Figure 16A shows a case where the TCI state #0 corresponding to TRP#1 and TRP#2 is activated, so that the TCI state pair (here, '0' and '2') is mapped to the same code point. Similarly, Figure 16B shows a case where the TCI state #0 corresponding to TRP#1 and TRP#2 is activated, so that the TCI state pair (here, '3' and '8') is mapped to the same code point.

[0173] Each code point in a given field of the DCI may be mapped to one or two TCI states. The maximum number of TCI state pairs (or DCI code points) that may be activated in multiple (e.g., all) panels may be set to a predetermined value (here, 8).

[0174] The maximum number of TCI state pairs (or corresponding DCI code points) that are activated for each panel may be defined. Although Fig. 16C shows a case where a maximum of four TCI state pairs are activated for each of panel #0 and panel #1, this is not limited to the case.

[0175] Option 2-4 The MAC CE used for activation of a TCI state may include a field corresponding to a panel ID (or a TCI state group ID) and indicate activation of a TCI state corresponding to a single panel (see FIG. 17A). FIG. 17A illustrates a case where the TCI state to be activated is specified using multiple bits, rather than a field corresponding to each TCI state (e.g., a one-bit field) being set.

[0176] Here, the case is shown where at least the TCI state corresponding to TRP#1 (e.g., TCI state #0,1='0') and the TCI state corresponding to TRP#2 (e.g., TCI state #0,2='2') are activated. TRP#1 may be replaced with CORESET pool index 0, and TRP#2 may be replaced with CORESET pool index 1.

[0177] In addition, each code point in a specified field included in the DCI may be associated with a TCI state corresponding to one panel (e.g., one or two TCI states activated for one panel by the MAC CE) (see FIG. 17B).

[0178] Here, TCI state #0 corresponding to TRP#1 and TRP#2 is activated, so that the TCI state pair (here, '0' and '2') is mapped to the same code point.

[0179] Each code point in a given field of the DCI may be mapped to one or two TCI states. The maximum number of TCI state pairs (or DCI code points) that may be activated in a panel may be set to a given value (here, 8).

[0180] Option 2-5 The MAC CE used for TCI state activation may include a field corresponding to each panel ID (or TCI state group ID) and may support simultaneous indication of activation of TCI states corresponding to multiple panels (e.g., panel #1 and panel #2) (see FIG. 18A).

[0181] 18A shows a case where a field (e.g., a 1-bit field) corresponding to each TCI state is not set, but the activated TCI state is specified using multiple bits. Also, the same MAC CE may specify the activated TCI state for each of multiple panels. Here, a case is shown where, among the activated TCI states, TCI state #0,1 corresponding to TRP#1 corresponds to a first panel (e.g., panel #0), and TCI state #0,2 corresponding to TRP#2 corresponds to a second panel (e.g., panel #1).

[0182] In addition, each code point of a predetermined field included in the DCI may be associated with a TCI state of one or two panels (e.g., one or two TCI states activated by the MAC CE for one or two panels) (see Figure 18B).

[0183] Here, the TCI state #0 corresponding to TRP#1 (or panel #0) and TRP#2 (or panel #1) is activated, so the TCI state pair (here, '0' and '2') is mapped to the same code point. In this case, different TRPs can be associated with each panel. This makes it possible to appropriately set the correspondence between each panel and the TCI state even when multiple panels correspond to different TRPs.

[0184] Each code point in a given field of the DCI may be mapped to one or two TCI states. The maximum number of TCI state pairs (or DCI code points) that may be activated in a panel may be set to a given value (here, 8).

[0185] Variations In the Rel.16 MAC CE for single DCI based multi-TRP, one codepoint corresponds to one or two activated TCI states. For DCI codepoint '000', the first TCI state ID field is always present, and the second active TCI state field is an optional field that is present when the field indicating the presence or absence of the TCI state field (C field) is '1' (see Figures 19A and 19B).

[0186] The existing MAC CE configuration may be used as an activation indication of the TCI state for multi-panel (Rel.17 and later). In this case, the UE may be instructed to use it as an activation indication of the TCI state for single DCI-based multi-TRP (Rel.16) or as an activation indication of the TCI state for multi-panel (Rel.17 and later). For example, the R field included in the MAC CE may be used to notify the UE of which purpose it is to be used. When a predetermined upper layer parameter is set, the UE may determine the purpose of the MAC CE based on the R field (or the switching indication field).

[0187] Also, the presence or absence of the second TCI state field may be specified by the C field included in the MAC CE. For example, if two panels are activated for TCI state #0, the second TCI state field may be present and two TCI states may be mapped to the DCI code point (see FIG. 19B).

[0188] <Option 3> The DL / UL panel information (or the association between the panel and the TCI status) may be determined when the TCI status is indicated by the DCI. For example, the panel ID may be notified by using a predetermined field included in the DCI. The predetermined field may be provided separately from the field for notifying the TCI status, or the number of bits in the field for notifying the TCI status may be increased and used to notify the panel ID.

[0189] Option 3-1 Panel information (e.g., a field for notifying panel ID) is not included in MAC CE (see FIG. 20A), and a field for panel notification (e.g., a panel field) may be set in DCI (see FIG. 20B). Here, a case is shown in which the field for panel notification is set separately from the field for notifying TCI status. The code point of the field for notifying TCI status is mapped to the TCI status activated in MAC CE.

[0190] The panel notification field included in the DCI may be present only under a predetermined condition, which may be, for example, when one or more DCI formats (for example, DCI format 1_1 / 1_2 or DCI format 0_1 / 0_2) are set by higher layer signaling.

[0191] When the DCI for beam instruction for the common TCI framework is performed by DCI format 1_1 / 1_2 without DL assignment (e.g., DL assignment), the DCI field for DL ​​assignment is not used. In such a case, the unused field may be used as a field for panel notification.

[0192] Option 3-2 Panel information (e.g., a field for notifying panel ID) is included in the MAC CE (see FIG. 21A), and the TCI state is activated for each panel. A field for panel notification (e.g., a panel field) may also be set in the DCI (see FIG. 21B). Here, the case is shown where the field for panel notification is set separately from the field for notifying TCI state. Note that any of the configurations shown in Option 2 may be applied to the MAC CE configuration.

[0193] The TCI state activated in the MAC CE is mapped to the code point of the TCI state notification field. The mapping between the code point of the TCI state notification field of the DCI and the TCI state may be set separately (differently) for each panel.

[0194] Also, the code points in the panel notification field (e.g., '0' and '1') may correspond to TCI states corresponding to different panels. Figure 21B shows a case where the code point '0' in the panel notification field corresponds to the activated TCI state of panel #0, and the code point '1' in the panel notification field corresponds to the activated TCI state of panel #1.

[0195] The mapping between the codepoint of the TCI status indication field and the TCI status may be applied taking into account the panel indication field, and the UE can determine the TCI status corresponding to each panel based on the codepoint of the TCI status indication field and the panel specified in the panel indication field.

[0196] (Variation 1) In Options 2-1 / 2-3 / 2-5 / 3-2, the activated TCI state may be configured to correspond to a plurality of panels (Configuration 1), or may not be configured to correspond to a plurality of panels (Configuration 2).

[0197] Configuration 1 For example, the UE may not assume that the activated TCI state is associated with multiple panels when the TCI state is activated by the MAC CE, e.g., the UE may not assume that the MAC CE shown in Figures 22A and 22B (where TCI state #0 is activated in both panel #0 and panel #1) is activated.

[0198] Configuration 2 Alternatively, the UE may assume that when a TCI state is activated by the MAC CE, the activated TCI state may be associated with multiple panels. For example, the UE may assume the MAC CE as shown in Figures 22A and 22B (where TCI state #0 is activated in both panel #0 and panel #1).

[0199] In this case, the same TCI state (here, TCI state #0) corresponding to a different panel may be mapped to a different code point in the TCI state notification field (see FIG. 22C).

[0200] For example, for the DCI code points of option 2-1, at least one of rules 1 to 3 of option 2-1 may be used. Alternatively, the code points of the TCI state notification field of the DCI may be mapped (or associated) with the TCI states activated in all panels, first in the order of index i of Ti, and then in the order of panel IDs (or TCI state group IDs).

[0201] (Variation 2) If a Panel ID is set / indicated for a joint DL / UL TCI, the Panel ID / Panel information may apply to both DL and UL, UL only, or DL ​​only.

[0202] If a Panel ID is set / indicated for a separate DL TCI, the Panel ID / Panel Information may apply to the DL only.

[0203] If a Panel ID is set / indicated for a separate UL TCI, the Panel ID / Panel Information may apply to the UL only.

[0204] When two panel IDs are configured / indicated by the RRC / MAC CE / DCI, the two panel IDs may be applied to DL and UL.

[0205] Figure 23A shows the case where the Panel ID for DL ​​and the Panel ID for UL are configured by the RRC (e.g., higher layer parameters related to TCI state), and Figure 23B shows the case where notification of the TCI state activated in the Panel ID for UL and the Panel ID for DL ​​is supported by the MAC CE.

[0206] In a MAC CE, if a joint DL / UL TCI is activated, two panels may be used for DL ​​and UL respectively. In a MAC CE, if a separate DL / UL TCI is activated, two panels may be used for DL ​​TCI and UL TCI respectively.

[0207] For a joint DL / UL TCI, two panels each may be used in the DL and UL, utilizing a common source reference RS for the DL and UL.

[0208] For a separate DL / UL TCI, two panels each for the DL TCI and UL TCI may be utilized.

[0209] The joint DL / UL TCI may be included in two groups for DL and UL respectively (a TCI state group for DL and a TCI state group for UL) (see FIGS. 24A and 24B). In FIG. 24A, a case is shown where a panel ID (or a TCI state group ID) is set for the TCI state group for DL (TCI-state-group for DL) in the upper layer parameters regarding the TCI state. In this case, the panel may be applied only to DL / DL TCI.

[0210] In FIG. 24B, a case is shown where a panel ID (or a TCI state group ID) is set for the TCI state group for UL (TCI-state-group for UL) in the upper layer parameters regarding the TCI state. In this case, the panel may be applied only to UL / UL TCI.

[0211] (Variation 3) In each option of the second aspect, the UE may apply at least one of the following UE operations 1 to UE operation 3.

[0212] <UE operation 1> The UE may expect that a panel ID (or a TCI state group ID) is provided for each TCI state.

[0213] <UE operation 2> The UE may or may not expect that a panel ID (or a TCI state group ID) is provided for the TCI state. For example, when the panel ID (or the TCI state group ID) is not provided, the UE may autonomously determine the panel selection for DL / UL (UE implementation).

[0214] <UE operation 3> Alternatively, if the panel ID (or the TCI status group ID) is not provided, a specific value or a default value may be applied as the panel ID (or the TCI status group ID). The specific value or the default value may be, for example, 0 (or 1).

[0215] (UE capability information) In the above first and second aspects, the following UE capabilities may be configured. Note that the following UE capabilities may be interpreted as parameters (e.g., higher layer parameters) configured in the UE from a network (e.g., a base station).

[0216] UE capability information regarding whether multiple UE panels are supported may also be defined.

[0217] UE capability information regarding the number of UE panels may be defined.

[0218] UE capability information regarding whether a different number of antenna ports / beams / RSs is supported for each UE panel may be defined.

[0219] UE capability information regarding the maximum number of antenna ports / beams / RS that can be set / instructed for DL / UL of each panel may be defined.

[0220] In the CSI / beam report, UE capability information regarding whether or not Panel ID is supported may be defined.

[0221] UE capability information may be defined regarding whether to support group-based CSI / beam reporting, with each group corresponding to a panel.

[0222] UE capability information regarding whether or not to support beams (e.g., CRI / SSBRI) corresponding to multiple panels in the CSI / beam report may be defined.

[0223] UE capability information regarding whether to support a panel ID (or TCI state group ID) set / indicated in RRC for TCI state setting / MAC CE for TCI state activation / DCI for TCI state indication may be defined.

[0224] UE capability information regarding the maximum number of activated TCI states may be defined.

[0225] UE capability information regarding the maximum number of TCI states that may be activated per panel may be defined.

[0226] The first and second aspects may be applied to a UE that supports / reports at least one of the above-mentioned UE capabilities. Alternatively, the first and second aspects may be applied to a UE that is configured by the network.

[0227] (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.

[0228] 25 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).

[0229] 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.

[0230] 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.

[0231] 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))).

[0232] 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.

[0233] 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).

[0234] 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.

[0235] 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).

[0236] 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.

[0237] 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.

[0238] The user terminal 20 may be a terminal compatible with at least one of communication methods such as LTE, LTE-A, and 5G.

[0239] 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.

[0240] 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.

[0241] 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.

[0242] 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.

[0243] 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).

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0248] 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.

[0249] 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.

[0250] 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.

[0251] 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.

[0252] 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).

[0253] (base station) 26 is a diagram showing an example of the configuration of a base station according to an embodiment. The base station 10 includes a control unit 110, a transceiver unit 120, a transceiver antenna 130, and a transmission line interface 140. Note that one or more of each of the control unit 110, the transceiver unit 120, the transceiver antenna 130, and the transmission line interface 140 may be provided.

[0270] The transmitting / receiving unit 120 may transmit information related to the resource of the measurement signal. The control unit 110 may perform control such that, when a measurement result of the measurement signal is reported from a terminal, multiple measurement results corresponding to multiple panel IDs are not reported for the same resource identifier of the measurement signal.

[0271] The transceiver 120 may transmit information relating to an association between a transmission configuration indicator (TCI) and a panel ID to the terminal.

Note that the user terminal 20 may include one or more of each of the control unit 210, the transmitting / receiving unit 220, and the transmitting / receiving antenna 230.

[0273] 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.

[0274] The control unit 210 performs overall control of the user terminal 20. The control unit 210 can be configured with a controller, a control circuit, and the like that are explained based on common understanding in the technical field to which the present disclosure relates.

[0283] Whether or not to apply the DFT process may be based on the setting of transform precoding. When transform precoding is enabled for a certain channel (e.g., PUSCH), the transceiver 220 (transmission processor 2211) may perform the DFT process as the transmission process to transmit the channel using a DFT-s-OFDM waveform, and may not perform the DFT process as the transmission process if transform precoding is enabled for the channel.

[0284] The transceiver unit 220 (RF unit 222) may perform modulation to a radio frequency band, filtering, amplification, and the like on the baseband signal, and transmit the radio frequency band signal via the transceiver antenna 230.

[0285] On the other hand, the transceiver unit 220 (RF unit 222) may perform amplification, filtering, demodulation to a baseband signal, etc. on the radio frequency signal received by the transceiver antenna 230.

[0286] The transceiver 220 (reception processing unit 2212) may apply reception processing such as analog-to-digital conversion, FFT processing, IDFT processing (if necessary), filtering, demapping, demodulation, decoding (which may include error correction decoding), MAC layer processing, RLC layer processing, and PDCP layer processing to the acquired baseband signal, and acquire user data, etc.

[0287] The transceiver 220 (measurement unit 223) may perform measurements on the received signal. For example, the measurement unit 223 may perform RRM measurements, CSI measurements, etc. based on the received signal. The measurement unit 223 may measure received power (e.g., RSRP), received quality (e.g., RSRQ, SINR, SNR), signal strength (e.g., RSSI), propagation path information (e.g., CSI), etc. The measurement results may be output to the control unit 210.

[0288] In addition, the transmitting section and the receiving section of the user terminal 20 in the present disclosure may be configured by at least one of the transmitting / receiving section 220, the transmitting / receiving antenna 230, and the transmission path interface 240.

[0289] The transmitting / receiving unit 220 may receive information related to the resource of the measurement signal. When reporting the measurement result of the measurement signal, the control unit 210 may perform control so as not to report multiple measurement results corresponding to multiple panel IDs for the same resource identifier of the measurement signal.

[0290] The information on the measurement signal resource may be information on resource identifiers of measurement signals associated with multiple panel IDs. The information on the measurement signal may be information on resource identifiers of one or more measurement signals included in a group corresponding to a panel. The control unit 210 may perform control so as not to report the resource identifier of the same measurement reference signal in multiple groups.

[0291] The transceiver 220 may receive information relating to an association between a transmission configuration indicator (TCI) and a panel ID. When reporting a measurement result of a measurement signal, the control unit 210 may support reporting of multiple measurement results corresponding to multiple panels for the same resource identifier of the measurement signal.

[0292] Information on the panel ID may be included in the upper layer parameters used to set the TCI state. Information on the panel ID may be included in the MAC CE used to activate the TCI state. The association between the TCI and the panel ID is notified by the code point of the field used to notify the TCI state included in the downstream control information, or the code point of the field used to notify the TCI state included in the downstream control information and the code point of another field.

[0293] (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.

[0294] 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.

[0295] 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. 28 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.

[0296] 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.

[0297] 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.

[0298] 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.

[0299] 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.

[0300] 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.

[0301] 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.

[0302] 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.

[0303] 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.

[0304] 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).

[0305] 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.

[0306] 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.

[0307] (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.

[0308] 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.

[0309] 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.

[0310] 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.

[0311] 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.

[0312] 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.

[0313] 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.

[0314] 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.

[0315] 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.

[0316] 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.

[0317] 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.

[0318] 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.

[0319] 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.

[0320] 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.

[0321] 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.

[0322] 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.

[0323] 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.

[0324] 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.

[0325] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell", "carrier", etc. in this disclosure may be replaced with "BWP".

[0326] 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.

[0327] In addition, the information, parameters, etc. described in the present disclosure may be represented using absolute values, may be represented using relative values ​​from a predetermined value, or may be represented using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

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.

[0329] The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. For example, the data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0330] 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.

[0331] 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.

[0332] 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.

[0333] 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).

[0334] 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).

[0335] 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).

[0336] Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0337] 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.

[0338] As used in this disclosure, the terms "system" and "network" may be used interchangeably. A "network" may refer to devices included in the network (e.g., base stations).

A base station may also be referred to by terms such as a macro cell, a small cell, a femto cell, a pico cell, etc.

[0341] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the entire coverage area of ​​the base station can be partitioned into multiple smaller areas, and each smaller area can also be provided with communication services by a base station subsystem (e.g., a small base station for indoor use (Remote Radio Head (RRH))). The term "cell" or "sector" refers to a part or the entire coverage area of ​​a base station and / or a base station subsystem that provides communication services in this coverage.

[0342] In this disclosure, the terms "Mobile Station (MS)", "user terminal", "User Equipment (UE)", "terminal", etc. may be used interchangeably.

[0344] At least one of the base station and the mobile station may be called a transmitting device, a receiving device, a wireless communication device, etc. At least one of the base station and the mobile station may be a device mounted on a moving body, the moving body itself, etc. The moving body may be a vehicle (e.g., a car, an airplane, etc.), an unmanned moving body (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). At least one of the base station and the mobile station may include a device that does not necessarily move during communication operation. 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.

[0345] 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)). In this case, the user terminal 20 may be configured to have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" may be read as terms corresponding to terminal-to-terminal communication (for example, "sidelink"). For example, an uplink channel, a downlink channel, etc. may be read as a sidelink channel.

[0346] Similarly, the user terminal in the present disclosure may be interpreted as a base station. In this case, the base station 10 may be configured to have the functions of the user terminal 20 described above.

[0347] In the present disclosure, an operation performed by a base station may be performed by its upper node in some cases. It is clear that in a network including one or more network nodes having base stations, various operations performed for communication with terminals may be performed by the base station, one or more network nodes other than the base station (such as, but not limited to, a Mobility Management Entity (MME) and a Serving-Gateway (S-GW)), or a combination thereof.

[0348] Each aspect / embodiment described in this disclosure may be used alone, in combination, or switched according to implementation.

[0351] Any reference to an element using a designation such as "first," "second," etc., used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must precede the second element in some way.

[0352] The term "determining" as used in this disclosure may encompass a wide variety of actions. For example, "determining" may be considered to be judging, calculating, computing, processing, deriving, investigating, looking up, search, inquiry (e.g., looking up in a table, database, or another data structure), ascertaining, and the like.

[0354] Also, "determination" may be considered to be "deciding" resolving, selecting, choosing, establishing, comparing, etc. That is, "determination" may be considered to be "deciding" to perform some action.

[0355] Additionally, "judgment (decision)" may be interpreted as "assuming," "expecting," "considering," etc.

[0356] The "maximum transmit power" in this disclosure may mean the maximum value of transmit power, may mean the nominal UE maximum transmit power, or may mean the rated UE maximum transmit power.

[0357] As used in this disclosure, the terms "connected," "coupled," or any variation thereof, refer to any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are "connected" or "coupled" to each other.

[0360] When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Further, when used in this disclosure, the term "or" is not intended to be an exclusive or.

[0361] In this disclosure, where articles have been added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0362] Although the invention according to the present disclosure has been described in detail above, it is clear to those skilled in the art that the invention according to the present disclosure is not limited to the embodiments described in the present disclosure. The invention according to the present disclosure can be implemented as modified and altered forms without departing from the spirit and scope of the invention defined based on the description of the claims. Therefore, the description of the present disclosure is intended to be illustrative and does not have any limiting meaning on the invention according to the present disclosure.
