[0051] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0052] (1) Channel State Information (CSI) measurement and reporting framework.

[0053] In New Radio (NR), CSI measurement and reporting are based on the CSI framework. The CSI framework comprises at least one of the following: CSI report settings, CSI resource settings, a Non-Zero Power (NZP) CSI-RS resource set, and an SSB resource set. Specifically, the CSI report configuration can be set to periodic reporting, semi-persistent reporting, or aperiodic reporting, and the time-domain characteristics of the resources corresponding to the CSI resource settings can also be configured as periodic, semi-persistent, or aperiodic.

[0054] The configuration framework for CSI measurement and reporting includes the following:

[0055] 1. A CSI report setting can be associated with a maximum of 3 CSI resource settings, including: CSI resource settings for channel measurement, CSI resource settings for interference measurement (IM) (e.g., CSI-IM resource settings), and non-zero power CSI resource settings for interference measurement (e.g., NZP-CSI-RS resource settings).

[0056] 2. An aperiodic CSI resource setting may contain multiple CSI-RS resource sets, such as an NZP-CSI-RS resource set or a CSI interference measurement (e.g., CSI-IM) resource set, and a Synchronization Signal and / or Physical Broadcast Channel Block (SSB) measurement resource set. A periodic or semi-continuous CSI resource setting may contain only one CSI-RS resource set and one SSB measurement resource set.

[0057] 3. A CSI-RS resource set may contain multiple CSI-RS resources (such as resources of CSI-IM or NZP-CSI-RS).

[0058] 4. An SSB measurement resource set includes multiple SSBs.

[0059] (2) Beam measurement.

[0060] Communication standards only support beam measurement via CSI-RS or SSB, with CSI-RS for beam measurement having only 1 to 2 ports. SSB is a periodic reference signal, while CSI-RS for beam measurement can be periodic, semi-continuous, or aperiodic.

[0061] Beam measurement in Releases 15 and 16 was limited to the serving cell. Release 15 only supported Layer 1 Reference Signal Receiving Power (L1-RSRP) measurement, while Release 16 introduced Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) to incorporate inter-cell or inter-user interference into the beam measurement. In Release 17's Inter-cell Beam Management and Inter-cell Transmission Reception Point (TRP) projects, L1 beam measurement of neighboring cells that are on the same frequency and synchronized with the current serving cell was supported. In Release 18's Mobility Enhancement project, L1 beam measurement of neighboring cells that are asynchronous and on different frequencies was supported, but both only supported SSB-based L1-RSRP measurement. After performing L1 beam measurement according to the network-configured measurement resources, the terminal selects a portion of the beams to report based on the measurement results.

[0062] (3) Beam reporting.

[0063] The terminal can select appropriate beams for reporting based on the full-bandwidth beam measurement results. The measurement quantities for full-bandwidth beam measurement can be L1-RSRP / Layer 1 Reference Signal Receiving Quality (L1-RSRQ) / L1-SINR. Beam reporting can be group-based or non-group-based. For non-group-based beam reporting, the terminal selects up to four beams from all measurement resources configured on the network side for reporting, based on the measurement quantities. For group-based beam reporting, in versions 15 / 16, the terminal selects a pair of beams that can be simultaneously received by the UE for reporting based on the measurement results. The reported content includes the measurement resource index and its corresponding measurement value. The measurement resource index CRI / SSBRI is the index of the measurement resource in its corresponding measurement resource set (e.g., NZP-CSI-RS resource set or CSI-SSB resource set). The time-domain characteristics of the reporting are similar to those of CSI-RS measurement resources, including periodic reporting, semi-persistent reporting, and aperiodic reporting, as detailed below:

[0064] Periodic reporting: Associated periodic CSI-RS resources, the reported resources are PUCCH resources, which are configured by the network through Radio Resource Control (RRC).

[0065] Semi-persistent reporting; can be associated with periodic or semi-persistent CSI-RS resources. The reported resources can be Physical Uplink Control Channel (PUCCH) resources or PUSCH resources. The PUCCH resources are determined by the Media Access Control (MAC) Control Element (CE) signaling, and the Physical Uplink Shared Channel (PUSCH) resources are determined by the Downlink Control Information (DCI).

[0066] Aperiodic reporting: can be associated with periodic, semi-persistent, or aperiodic CSI-RS resources. The reporting resource is the PUSCH resource, which is determined by DCI.

[0067] In the version 17 multi-transmission and reception node project, the group-based beam reporting method has been enhanced. The terminal can select up to 4 pairs of beams that the UE can receive simultaneously from the measurement resources configured by the network for reporting. Different beams in each pair of beams correspond to different transmission and reception nodes, thereby ensuring that the network can send the pair of beams simultaneously.

[0068] In the L1 / L2-Triggered Mobility (LTM) project version 18, L1 reporting for handover was introduced, namely LTM CSI Report Configuration (CSI-ReportConfig). In an L1 report for handover, a terminal can report up to 4 cells, with each cell reporting 4 beam measurements, for a maximum of 16 beams and their corresponding measurements.

[0069] To reduce reporting overhead and beam reporting latency, version 19 introduces a terminal event-triggered L1 beam reporting technology. This means that the terminal will only perform L1 beam reporting if the conditions corresponding to the triggering event are met. This terminal event-triggered L1 beam reporting technology is implemented within the unified TCI framework.

[0070] (4) Unify the TCI framework.

[0071] To reduce signaling overhead and simplify beam indication mechanisms, Release 17 introduced Unified TCI. The Unified TCI framework supports two modes: joint and separate. In joint mode, the uplink and downlink channels share the same beams as the reference signal, while in separate mode, the downlink and uplink channels share the same beams, but the uplink and downlink beams differ.

[0072] For the combined mode, the network side only needs to configure a list of TCI states, and then determine the beam of the UE through MAC CE activation and DCI indication; for the separated mode, the network side needs to configure a list of TCI states for the downlink channel and reference signals, and configure a list of TCI-UL states for the uplink channel and reference signals. For the activation and indication of TCI states in the separated mode, the beam pairs are activated in the form of beam pairs (i.e., one TCI state + one TCI-UL state) through MAC CE, and then one beam pair is determined from the activated beam pairs through DCI.

[0073] (5) Beam measurement and reporting triggered by the terminal.

[0074] The discussion on the beam measurement and reporting technology triggered by the terminal in the 3rd Generation Partnership Project (3GPP) is as follows:

[0075] 1. The triggering events include:

[0076] Event 2: There is at least one same candidate beam whose measurement result corresponding to the candidate beam is greater than the measurement result of the beam currently used by the terminal by a certain threshold for no less than a preset number of times within a time window, or there is at least one candidate beam whose measurement result is greater than the measurement result of the beam currently used by the terminal.

[0077] Event 1: The number of times the measurement result corresponding to the currently used beam is lower than a certain threshold within a time window is not less than a preset number of times, or the measurement result corresponding to the currently used beam is lower than a certain threshold.

[0078] Event 7: There is at least one same candidate beam whose measurement result is greater than the measurement result of the Qth (Q < P) TCI state with the highest measurement result among the currently activated P TCI states by a certain threshold for no less than a preset number of times within a time window, or there is a candidate beam whose measurement result is greater than the measurement result of the Qth (Q < P) TCI state with the highest measurement result among the currently activated P TCI states by a certain threshold.

[0079] For the triggering events, the determination of the corresponding measurement RS is as follows: [[ID=二十四]]

[0080] a). The measurement RS corresponding to the candidate beam: It is determined by RRC configuration.

[0081] b). Measurement RS corresponding to the beam currently used by the terminal: Determined according to the Indicated TCI state, including two schemes: one is to determine according to the QCL resource (source) RS corresponding to the Indicated TCI state (e.g., CSI-RS); the other is to determine according to the QCL root resource (root source) RS corresponding to the Indicated TCI state (e.g., SSB).

[0082] c). Measurement RS corresponding to the Q-th (Q < P) TCI state with the highest measurement result among the currently activated P TCI states: Determined according to the activated TCI state, including two schemes: one is to determine according to the QCL resource (source) RS corresponding to the activated TCI state (e.g., CSI-RS); the other is to determine according to the QCL root resource (root source) RS corresponding to the activated TCI state (e.g., SSB).

[0083] The reporting mode (e.g., for event 2) is as follows:

[0084] Mode A:

[0085] Step 1: The terminal sends a trigger reporting indication message (1 bit) on the PUCCH resource.

[0086] Step 2: The terminal receives feedback information from the network side (e.g., Physical Downlink Control Channel (PDCCH)), and the PDCCH is used to schedule a PUSCH resource carrying a report.

[0087] Step 3: The terminal sends a report on the PUSCH resource.

[0088] Mode B:

[0089] Step 1: The terminal sends a trigger reporting indication message (1 bit) on the PUCCH resource.

[0090] Step 2: The terminal sends a report on the uplink resource (CG-PUSCH) pre-allocated by the network. [[ID=Z]]

[0091] The reporting content (e.g., for event 2) is as follows:

[0092] Report M beams, and at least one of the M beams meets the condition.

[0093] The RRC configuration terminal is configured to always report the measurement results of the current beam; if always reported, then M+1 beams are reported.

[0094] (6) Multi-TRP (mTRP).

[0095] 3GPP has proposed multi-TRP / multi-panel scenarios. Multi-TRP transmission can increase transmission reliability and throughput performance. For example, a UE can receive the same or different data from multiple TRPs. Multi-TRP transmission scenarios include the following:

[0096] 1) As shown in Figure 2(a), multi-panel transmission within the same TRP.

[0097] 2) As shown in Figure 2(b), multi-TRP / panel transmission between multiple TRPs, ideal backhaul.

[0098] 3) As shown in Figure 2(c), the multi-TRP / panel transmission between multiple TRPs is a non-ideal backhaul.

[0099] 3GPP Release 16 standardizes multi-TRP / multi-panel scenarios, which can increase transmission reliability and throughput performance. For example, the UE can receive the same or different data from multiple TRPs. Inter-TRP communication can be categorized into ideal backhaul and non-ideal backhaul. In non-ideal backhaul scenarios, there is significant latency in information exchange between multiple TRPs, making independent scheduling more suitable, with ACK / NACK and CSI reports fed back to each TRP separately. This is typically applicable to multi-DCI scheduling, where each TRP sends its own PDCCH, each PDCCH schedules its own PDSCH, and multiple Control Resource Sets (CORESETs) configured for the UE are associated with different RRC parameters (e.g., the CORESETPoolIndex), corresponding to different TRPs. The multiple PDSCHs scheduled by multiple DCIs may have non-overlapping, partially overlapping, or completely overlapping time-frequency resources. On overlapping time-frequency resources, each TRP performs independent precoding according to its own channel, and the UE receives multi-layer data streams belonging to multiple PDSCHs in a non-coherent joint transmission (NCJT) manner.

[0100] In an ideal backhaul scenario, multiple TRPs can exchange scheduling information and UE feedback information in real time. Besides scheduling multiple PDSCHs through multiple DCIs as described above, single DCIs can also schedule PDSCHs, including the following transmission schemes:

[0101] Spatial Division Multiplexing (SDM): NCJT transmission of different data layers from different TRPs within the same transmission block (TB).

[0102] Frequency Division Multiplexing (FDM): Different frequency domain resources mapped to the same redundancy version (RV) of the same TB originate from different TRPs, or different RVs of the same TB are mapped to different frequency domain resources and originate from different TRPs.

[0103] Time Division Multiplexing (TDM): Multiple repetitions of different RVs within the same TB originate from different TRPs, such as repetition within one time slot or repetition across multiple time slots.

[0104] At this point, ACK / NACK feedback and CSI reports can be sent to any TRP.

[0105] (7) mTRP beam reporting.

[0106] Considering the possibility of multiple TRPs being transmitted simultaneously and received simultaneously by the UE under sDCI SDM transmission mode and multi-DCI (mDCI) scheduled PDSCH transmission, 3GPP Release 17 proposed group-based beam reporting technology for mTRP. This means that the terminal can select up to 4 pairs of beams that the UE can receive simultaneously from the measurement resources configured by the network for reporting, and different beams in each pair of beams correspond to different transmission and reception nodes, thereby ensuring that the network can transmit this pair of beams simultaneously.

[0107] (8) mTRP beam indication.

[0108] Under the unified TCI framework, the beam indication of mTRP differs for different scheduled transmission modes, as follows:

[0109] mDCI-based mTRP scheduling transport mode:

[0110] Each control resource set pool index (CORESETPoolindex) activates S TCI code points. For a TCI code point, it can correspond to 1 joint TCI, or it can correspond to 1 pair of TCI state / TCI-UL state.

[0111] If S = 1, the joint TCI corresponding to the activated TCI code point is the indicator TCI state, or the TCI state / TCI-UL state corresponding to the activated TCI code point is the indicator TCI state / TCI-UL state; if S > 1, DCI indicates one of the S activated TCI code points as the indicator TCI state / TCI-UL state.

[0112] The TCI / TCI-UL state indicated for CORESETPoolindex#0 is the first indicated TCI / TCI-UL state, and the TCI / TCI-UL state indicated for CORESETPoolindex#1 is the second indicated TCI / TCI-UL state.

[0113] sDCI-based mTRP scheduling transport mode:

[0114] MAC CE activates S TCI code points. For a TCI code point, it can correspond to 2 joint TCIs, or it can correspond to 2 pairs of TCI states / TCI-UL states.

[0115] If S = 1, then the two joint TCIs corresponding to the activated TCI code point, or the two pairs of TCI states / TCI-UL states, are the indication TCI state and the indication TCI-UL state; if S > 1, DCI indicates one of the S activated TCI code points as the indication TCI state and the indication TCI-UL state.

[0116] In the two joint TCIs, or the two pairs of TCI states / TCI-UL states, the TCI state / TCI-UL state that appears earlier in the sequence is the first indicated TCI state / TCI-UL state, and the one that appears later is the second indicated TCI state / TCI-UL state. For example, in the separate TCI mode, if the TCI code points indicated by the DCI contain {{TCI state #1, TCI-UL state #1}, {TCI state #2, TCI-UL state #2}}, then TCI state #1 is the first indicated TCI state, TCI-UL state #1 is the first indicated TCI-UL state, TCI state #2 is the second indicated TCI state, and TCI-UL state #2 is the second indicated TCI-UL state.

[0117] R19 discusses User Equipment Initiated Beam Reporting (UEIBR) technology, but only for single TRP scenarios, not for mTRP scenarios. Considering that UEIBR can reduce beam reporting latency and overhead, and beam measurement and reporting are essential steps in mTRP FR2 scenarios, there is an urgent need in the field for a beam reporting method applicable to multi-TRP (mTRP) scenarios with terminal-triggered reporting. Therefore, this application provides a wireless communication method that enables the terminal to evaluate beam reporting in mTRP scenarios, i.e., it enables terminal-triggered beam reporting, thereby improving beam reporting performance.

[0118] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0119] Figure 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application.

[0120] As shown in Figure 3, the wireless communication method 200 may include at least some of the following:

[0121] S201, the terminal performs beam reporting when at least one of at least one first reference signal (RS) and at least one second RS satisfies the triggering condition for beam reporting; wherein, the at least one first RS is associated with at least one TCI state, the TCI state of the at least one TCI state is an indication TCI state or an active TCI state, the at least one second RS is associated with at least one set of reference signal resources for beam measurement or at least one combination of reference signal resources for beam measurement, the TCI states associated with different reference signal resources in the same set of at least one set of reference signal resources are the same, and the TCI states associated with different reference signal resources in any combination of at least one combination of reference signal resources are different.

[0122] For example, the association of the first RS with the TCI state may refer to the first RS being a QCL RS or a QCL root RS of the TCI state.

[0123] For example, when different reference signal resources in the reference signal resource combination are associated with different TCI states, reference signal resources at the same location in each reference signal resource combination are associated with the same TCI state. For example, the network side configures four reference signal resource combinations: {RS#1, RS#2}, {RS#3, RS#4}, {RS#5, RS#6}, and {RS#7, RS#8}. The RSs in the reference signal resource combination can be associated with TCI states; for example, the first RS in each reference signal resource combination is associated with TCI state #1, and the second RS is associated with TCI state #2.

[0124] For example, the reference signal resource set or the combination of reference signal resources may also be referred to as a candidate beam measurement reference signal resource set, etc. Both the first RS and the second RS may be referred to as the RS corresponding to the reported associated measurement resources, or an RS used for conditional beam reporting evaluation. The first RS or the second RS includes, but is not limited to: CSI-RS, TRS, SSB, etc., used for beamforming (BM).

[0125] For example, at least one of the at least one first reference signal (RS) and at least one second RS satisfies the triggering condition for beam reporting, including: the at least one first RS and / or the at least one second RS satisfies the triggering condition.

[0126] For example, the terminal determines, according to network instructions, that the at least first RS is an RS associated with the at least one TCI state indicated by the network, so that the terminal performs terminal-triggered beam reporting based on the at least one first RS.

[0127] For example, the terminal determines, according to the network indication, that the at least first RS is an RS associated with the at least one TCI state indicated by the network, and determines that the at least one reference signal resource set is a reference signal resource set configured by the network-side device, such as a reference signal resource set configured by the network-side device, so that the terminal performs terminal-triggered beam reporting based on the at least one first RS and the at least one second RS.

[0128] For example, the terminal determines at least one reference signal resource set corresponding to the at least first RS and the at least one first RS according to the rules agreed upon in the protocol. For instance, the terminal determines the at least one reference signal resource set corresponding to the at least first RS and the at least one first RS based on the association relationship between the at least one reference signal resource set and the at least one TCI state. The association relationship between the at least one reference signal resource set and the at least one TCI state is agreed upon in the protocol.

[0129] For example, the terminal determines the at least one first RS based on information indicated by the network, and determines the at least one second RS based on the at least one set of reference signal resources or the at least one combination of reference signal resources. For instance, if the association between the at least one TCI state and the at least one first RS is indicated by the network, the terminal can determine the at least one first RS based on the at least one TCI state. If the at least one first RS includes a target first RS associated with a target TCI state, and the at least one set of reference signal resources includes a target set of reference signal resources associated with the target TCI state, the terminal can determine the RS associated with the target set of reference signal resources as the second RS corresponding to the target first RS. Alternatively, if each reference signal resource combination in the at least one combination of reference signal resources includes a target RS resource associated with the target TCI state, the terminal can determine the RS corresponding to the target RS resource as the second RS corresponding to the target first RS.

[0130] For example, the terminal can determine the at least one first RS and the at least one second RS based on the association relationship between the at least one TCI state and the at least one reference signal resource set. For instance, if the association relationship between the at least one TCI state and the at least one reference signal resource set is protocol-defined, the terminal can determine the at least one first RS based on the at least one TCI state. If the at least one first RS includes a target first RS associated with a target TCI state, and the at least one reference signal resource set includes a target reference signal resource set associated with the target TCI state, the terminal can determine the RS associated with the target reference signal resource set as the second RS corresponding to the target first RS.

[0131] Alternatively, the terminal can determine the at least one first RS and the at least one second RS based on the association relationship between the at least one TCI state and the at least one reference signal resource combination. For example, if the association relationship between the at least one TCI state and the at least one reference signal resource combination is agreed upon by a protocol, the terminal can determine the at least one first RS based on the at least one TCI state. If the at least one first RS includes a target first RS associated with a target TCI state, and each reference signal resource combination in the at least one reference signal resource combination includes a target RS resource associated with the target TCI state, the terminal can determine the RS corresponding to the target RS resource as the second RS corresponding to the target first RS.

[0132] For example, the terminal may determine the at least one first RS based on the at least one TCI state, and determine the at least one second RS based on the at least one set of reference signal resources or the at least one combination of reference signal resources.

[0133] For example, the at least one first RS includes the RS with the highest or lowest measurement result among the at least one TCI state-associated RSs; the at least one second RS includes the RS with the highest or lowest measurement result among the at least one set of reference signal resources or the at least one combination of reference signal resources.

[0134] For example, the at least one first RS includes the at least one RS associated with the TCI state, and the measurement result of the at least one first RS is the sum / linear mean / weighted mean of the measurement results of the at least one TCI state associated RS. The at least one second RS includes all RS associated with the same reference signal resource combination in the at least one reference signal resource set or the at least one reference signal resource combination, and the measurement result of the at least one second RS is the sum / linear mean / weighted mean of the measurement results of all RS associated with the same reference signal resource combination in the at least one reference signal resource set or the at least one reference signal resource combination.

[0135] It should be noted that the at least one reference signal resource set contains multiple reference signal resource sets corresponding to different TRPs, and one reference signal resource combination in the at least one reference signal resource combination contains multiple resources corresponding to different TRPs. The TRP identifier can be indicated by RS set identifier / PCI / CORESETPoolindex, etc.

[0136] For example, the terminal determines whether the triggering event is met based on at least one of the measurement results of the at least one first RS and the measurement results of the at least one second RS; when the triggering event is met, the terminal triggers the reporting process.

[0137] For example, the terminal determines whether the trigger event is satisfied based on at least one of the measurement results of the target first RS in the at least one first RS and the measurement results of the second RS corresponding to the target first RS in the at least one second RS; when the trigger event is satisfied, the terminal triggers a reporting process. Optionally, if the target first RS is associated with a target TCI state in the at least one TCI state, the second RS corresponding to the target first RS includes: RSs of the target reference signal resource set associated with the target TCI state in the at least one reference signal resource set, or RSs of the target TCI state in each reference signal resource combination in the at least one reference signal resource combination.

[0138] In this embodiment of the application, at least one of at least a first RS and at least one second RS is used to determine whether the triggering conditions for beam reporting are met, so that the terminal can perform beam reporting evaluation in the mTRP scenario, that is, it can realize beam reporting based on terminal triggering, thereby improving beam reporting performance.

[0139] It should be noted that the RS corresponding to the TCI status includes the RS indicated by the TCI status or the QCL RS of the RS.

[0140] In some embodiments, the at least one first RS includes at least one of the following:

[0141] The quasi-co-located (QCL) RS corresponding to each TCI state in the at least one TCI state;

[0142] The QCL RS corresponding to each TCI state in the at least one TCI state.

[0143] For example, the at least one first RS may include at least one of the following: a QCL RS corresponding to the RS ID contained in each TCI state in the at least one TCI state, and a QCL RS corresponding to the RS ID contained in each TCI state in the at least one TCI state.

[0144] In this embodiment, the terminal determines the QCL RS corresponding to each TCI state in the at least one TCI state, and / or the QCL RS of the QCL RS corresponding to each TCI state in the at least one TCI state, as the at least one first RS, so that the terminal can determine the at least one first RS based on the at least one TCI state, thereby realizing beam reporting based on terminal triggering.

[0145] In some embodiments, the at least one TCI state includes at least one of the following:

[0146] Among all indicated TCI states, the indicated TCI states of each reference signal resource set in the at least one reference signal resource set are associated;

[0147] Among all active TCI states, the first active TCI state associated with each reference signal resource set in the at least one reference signal resource set is the TCI state where the measurement result of the corresponding RS in the active TCI states associated with each reference signal resource set is the Q-th highest.

[0148] Among all TCI states associated with the first TCI code point, the active TCI states associated with each reference signal resource set in the at least one reference signal resource set are also included.

[0149] Of all indicated TCI states, the indicated TCI states of each reference signal resource in any reference signal resource combination in the at least one reference signal resource combination are associated;

[0150] Among all active TCI states, the second active TCI state is associated with each reference signal resource in any reference signal resource combination in the at least one reference signal resource combination. The second active TCI state is the TCI state where the measurement result of the corresponding RS in the active TCI state associated with each reference signal resource is the Q-th highest.

[0151] Among all TCI states associated with the first TCI code point, the active TCI states of each reference signal resource in any reference signal resource combination in the at least one reference signal resource combination are associated.

[0152] The TCI state with the highest corresponding RS measurement result among all indicated TCI states;

[0153] The TCI state with the lowest corresponding RS measurement result among all indicated TCI states;

[0154] Among all activated TCI states, the corresponding RS measurement result is the Q-th highest TCI state;

[0155] The TCI state with the highest RS measurement result among all TCI states associated with the first TCI code point;

[0156] The TCI state with the lowest corresponding RS measurement result among all TCI states associated with the first TCI code point.

[0157] For example, the first TCI code point is the TCI code point with the highest measurement result among all active TCI code points.

[0158] In this embodiment, since different TCI states may have different corresponding QCL RS or their corresponding QCL RS QCL RS, by refining the at least one TCI state, the at least one first RS state can be refined, enabling terminal-triggered beam reporting, thereby improving beam reporting performance and flexibility.

[0159] In some embodiments, the first TCI code point is one of the following:

[0160] The highest measurement result of RS among all active TCI code points is the Q-th highest TCI code point;

[0161] The lowest measurement result of RS among all active TCI code points is the Q-th highest TCI code point;

[0162] The sum of the RS measurements for all active TCI code points is the Q-th highest TCI code point.

[0163] For example, the first TCI code point may be determined according to at least one of the following methods:

[0164] For example, the at least one TCI state includes one or more indicative DL TCI states / indicative joint TCI states, such as indicative DL TCI states / indicative joint TCI states associated with each reference signal resource set. Alternatively, the at least one TCI state includes one or more active TCI states, such as the TCI state with the Q-th highest measurement result among the active TCI states associated with each reference signal resource set. Alternatively, the at least one TCI state includes one or more TCI states associated with the first TCI code point, such as a first TCI state or a second TCI state associated with the first TCI code point.

[0165] For example, the at least one TCI state includes an active TCI state associated with CORESETPoolindex#0 or an active TCI state associated with CORESETPoolindex#1.

[0166] 1. The Q-highest TCI code point with the lowest RS measurement result for all TCI states among all TCI code points;

[0167] 2. The highest measurement result of RS for all TCI states among all TCI code points is the Q-highest TCI code point;

[0168] 3. The Q-highest TCI code point is the sum of the RS measurement results corresponding to all TCI states among all TCI code points;

[0169] 4. The linear / weighted average or median of the measurement results of RS corresponding to all TCI states among all TCI code points, or the Q-highest TCI code point among the measurement results of a specific RS.

[0170] For example, assuming two reference signal resource sets are configured, and the network indicates two DL TCI states / joint TCI states, or a single activated TCI code point corresponds to two DL TCI states / joint TCI states, then the first DL TCI state / joint TCI state corresponds to the first reference signal resource set, and the second DL TCI state / joint TCI state corresponds to the second reference signal resource set. Based on this correspondence, the terminal can determine the RS corresponding to the first DL TCI state / joint TCI state and the RS corresponding to the second DL TCI state / joint TCI state as the first RS, and the RS associated with the first reference signal resource set and the RS associated with the second reference signal resource set as the second RS. It should be noted that in this case, the first reference signal resource set and the second reference signal resource set correspond to different TRPs.

[0171] In this embodiment, since different TCI code points are associated with different TCI states, and the QCL RS corresponding to different TCI states or the QCL RS of their corresponding QCL RS may be different, when defining the TCI state in the at least one TCI state through the first TCI code point, the at least one TCI state can be refined, and thus the at least one first RS can be refined. This enables beam reporting based on terminal triggering, thereby improving beam reporting performance and flexibility.

[0172] In some embodiments, the association between the at least one TCI state and the at least one reference signal resource set is a one-to-one association; the association between the at least one TCI state and different resources in any reference signal resource combination of the at least one reference signal resource combination is a one-to-one association; or the association between the at least one first RS and the at least one reference signal resource set is a one-to-one association.

[0173] For example, the association between two TCI states and two reference signal resource sets is one-to-one. For instance, the first TCI state corresponds to reference signal resource set #1, and the second TCI state corresponds to reference signal resource set #2.

[0174] For example, the association between the at least one TCI state and the at least one reference signal resource set is a one-to-one association.

[0175] For example, the association between the at least one TCI state and the different RSs in any reference signal resource combination of the at least one reference signal resource combination is a one-to-one association.

[0176] For example, the association between the at least one first RS and the at least one reference signal resource set is a one-to-one association, and the association between the at least one reference signal resource set and the at least one TCI state is a one-to-one correspondence.

[0177] In this embodiment, when the association between the at least one TCI state and the at least one reference signal resource set is one-to-one, or when the association between the at least one TCI state and different resources in any reference signal resource combination in the at least one reference signal resource combination is one-to-one, or when the association between the at least one first RS and the at least one reference signal resource set is one-to-one, the terminal can determine the association between the at least one first RS and the at least one second RS. For example, the terminal can determine the target first RS among the at least one first RS and the second RS corresponding to the target first RS among the at least one second RS. This allows the terminal to perform beam reporting evaluation based on at least one of the target first RS and the second RS corresponding to the target first RS.

[0178] In some embodiments, the at least one second RS includes at least one of the following:

[0179] Associate the RS of all reference signal resource sets in the at least one reference signal resource set;

[0180] Associate RSs of the same reference signal resource set in the at least one reference signal resource set;

[0181] Associate RSs of the same TCI state in at least one of the TCI states;

[0182] Associate the RS of all reference signal resource combinations in the at least one reference signal resource combination;

[0183] RSs associated with the same TCI state in at least one combination of reference signal resources.

[0184] For example, for a target first RS in the at least one first RS, the at least one second RS may include at least one of the following:

[0185] Associate the RS of all reference signal resource sets in the at least one reference signal resource set;

[0186] Associate RSs of the same reference signal resource set in the at least one reference signal resource set;

[0187] Associate RSs of the same TCI state in at least one of the TCI states;

[0188] Associate the RS of all reference signal resource combinations in the at least one reference signal resource combination;

[0189] RSs associated with the same TCI state in at least one combination of reference signal resources.

[0190] In this embodiment, by refining the at least one second RS, the terminal is not only able to realize beam reporting based on terminal triggering, thereby improving beam reporting performance, but also improving the flexibility of beam reporting.

[0191] In some embodiments, at least one of the at least one first RS and the at least one second RS satisfies the triggering condition, including:

[0192] At least one of the at least one first RS associated with the first TCI state in the at least one TCI state, and at least one of the at least one second RS associated with the first reference signal resource set in the at least one reference signal resource set, satisfies the first condition; or, at least one of the at least one first RS associated with the second TCI state in the at least one TCI state, and at least one of the at least one second RS associated with the first resource in each reference signal resource combination in the at least one reference signal resource combination, satisfies the first condition.

[0193] Wherein, the first reference signal resource set is associated with the first TCI state, and the first resource is associated with the second TCI state;

[0194] The first condition includes at least one of the following:

[0195] At least one of the measurements of the fourth RS is higher than the first threshold of the measurement of the third RS;

[0196] Within a preset time period, there is at least one measurement result of the fourth RS, and the number of times the measurement result of the third RS exceeds the second threshold is not less than the first preset number;

[0197] The measurement result of the third RS is lower than the third threshold;

[0198] Within a preset time period, the number of times the measurement result of the third RS is lower than the fourth threshold is not less than the second preset number of times.

[0199] For example, the third RS can be any of the first RS. The fourth RS can be any RS associated with the first reference signal resource set, or the fourth RS can be an RS associated with a first resource in any of the at least one reference signal resource combination.

[0200] In this embodiment, when at least one of the at least one first RS associated with the first TCI state in the at least one TCI state, and the at least one second RS associated with the first reference signal resource set in the at least one reference signal resource set, satisfies the first condition; or when at least one of the at least one first RS associated with the second TCI state in the at least one TCI state, and the at least one second RS associated with the first resource in each reference signal resource combination in the at least one reference signal resource combination, satisfies the first condition, it indicates that beam reporting can be performed at the TCI state granularity or at the TRP granularity, which can improve the flexibility of beam reporting.

[0201] It should be understood that at least one of the first threshold to the fourth threshold, the first preset number of times, and the second preset number of times can be agreed upon by a protocol, configured by the network, or determined by the terminal and reported to the network. This application does not specifically limit this.

[0202] In some embodiments, at least one of the at least one first RS and the at least one second RS satisfies the triggering condition, including:

[0203] At least one of the measurement results of the at least one first RS and the measurement results of the at least one second RS satisfies the second condition;

[0204] The second condition includes at least one of the following:

[0205] The measurement result of at least one second RS is higher than the fifth threshold of the measurement result of at least one first RS;

[0206] Within a preset time period, the number of times the measurement result of at least one second RS is higher than the sixth threshold of the measurement result of at least one first RS is not less than the third preset number;

[0207] The measurement result of at least one first RS is below the seventh threshold;

[0208] Within a preset time period, the number of times the measurement result of at least one first RS is lower than the eighth threshold is not less than the fourth preset number of times.

[0209] In this embodiment, when at least one of the measurement results of at least one first RS and the measurement results of at least one second RS satisfies the second condition, it indicates that the evaluation process of multiple TRPs can be simplified into a single evaluation process, thereby reducing the complexity of beam reporting.

[0210] It should be understood that at least one of the fifth to eighth thresholds, the third preset number of times, and the fourth preset number of times can be agreed upon through a protocol, configured by the network, or determined by the terminal and reported to the network. This application does not specifically limit this.

[0211] In some embodiments, the measurement result of the at least one first RS is one of the following:

[0212] The sum of the measurement results of at least one first RS;

[0213] The weighted average of the measurement results of at least one first RS;

[0214] The linear average of the measurement results of at least one first RS.

[0215] In other alternative embodiments, the measurement result of the at least one first RS may be the median, maximum, minimum value of the measurement results of the at least one first RS, or the measurement result of a specific first RS.

[0216] In this embodiment, by introducing different definitions of the measurement results of the at least one first RS, the terminal can perform terminal-triggered beam reporting evaluation based on the appropriate or expected measurement results of the at least one first RS, thereby improving the flexibility of beam reporting.

[0217] In some embodiments, the measurement result of the at least one second RS is one of the following:

[0218] The sum of measurement results of RSs associated with different reference signal resource sets in at least one second RS;

[0219] The weighted average of the measurement results of RSs associated with different reference signal resource sets in at least one second RS;

[0220] The linear average of the measurement results of RSs associated with different reference signal resource sets in at least one second RS;

[0221] The sum of measurement results of RSs that are associated with the same combination of reference signal resources in at least one second RS;

[0222] The weighted average of the measurement results of RSs associated with the same combination of reference signal resources in at least one second RS;

[0223] The linear average of the measurement results of RSs associated with the same combination of reference signal resources in at least one second RS.

[0224] In other alternative embodiments, the measurement result of the at least one second RS may be the median, maximum, minimum value of the measurement results of RSs associated with different sets of reference signal resources among the at least one second RS, or the measurement result of a specific first RS. Alternatively, the measurement result of the at least one second RS may be the median, maximum, minimum value of the measurement results of RSs associated with the same set of reference signal resources among the at least one second RS, or the measurement result of a specific second RS.

[0225] In this embodiment, by introducing different definitions of the measurement results of at least one second RS, the terminal can perform terminal-triggered beam reporting evaluation based on the measurement results of a suitable or other second RS, thereby improving the flexibility of beam reporting.

[0226] In some embodiments, before the terminal performs beam reporting, the method further includes:

[0227] The terminal receives first information, which includes at least one of the following: first indication information and second indication information;

[0228] Wherein, the first indication information is used to indicate the association relationship between the at least one TCI state and the at least one first RS, and the second indication information is used to indicate the association relationship between the at least one TCI state and at least one of the following: the at least one reference signal resource set, at least one reference signal resource in any reference signal resource combination in the at least one reference signal resource combination.

[0229] For example, the first indication information occupies 1 bit.

[0230] For example, the first indication information is used to indicate the association between the at least one TCI state and the at least one first RS, including but not limited to, the first indication information being used to indicate the control resource set pool index (CORESETPoolindex) corresponding to the first RS, or the applied indicated TCI state. For example, when the first indication information indicates the applied indicated TCI state, it can specifically indicate that the applied indicated TCI state is the first indicated TCI state or the second applied TCI state.

[0231] For example, the terminal can determine, based on the association relationship indicated by the first indication information, which TCI state the RS (i.e., the first RS) corresponding to the beam being used by the terminal for evaluating the beam reporting trigger conditions was obtained from.

[0232] In this embodiment, by receiving the first indication information or the second indication information, the terminal can determine the association between the at least one first RS and the at least one second RS. For example, the terminal can determine the target first RS among the at least one first RS and the second RS corresponding to the target first RS among the at least one second RS. This enables the terminal to perform beam reporting evaluation based on at least one of the target first RS and the second RS corresponding to the target first RS.

[0233] In some embodiments, the first information further includes at least one of the following:

[0234] Configuration information of the at least one reference signal resource set;

[0235] Configuration information of the at least one reference signal resource combination;

[0236] Configuration information for the triggering conditions;

[0237] Information indicating the RS type of the first RS;

[0238] Information indicating the RS type of the second RS.

[0239] For example, the configuration information of the triggering condition includes, but is not limited to: the identifier of the event / condition, the preset number of times the event / condition is met, the relevant configuration information of the time window, the threshold, etc.

[0240] For example, the RS type of the first RS or the RS type of the second RS includes, but is not limited to: CSI-RS, TRS, SSB, etc. for BM.

[0241] In this embodiment, by configuring relevant information for beam reporting evaluation in the mTRP scenario through the network, it can be ensured that the terminal can perform beam reporting evaluation in the mTRP scenario, that is, it can realize beam reporting based on terminal triggering, thereby improving beam reporting performance.

[0242] In some embodiments, the method 200 further includes:

[0243] If the fifth RS of at least one of the first RS and at least one of the second RS changes, the terminal performs at least one of the following:

[0244] Clear the count value of the beam reporting evaluation process to zero;

[0245] The count value associated with the beam reporting evaluation process of the fifth RS is cleared to zero;

[0246] Close the time window for the beam reporting evaluation process;

[0247] Restart the time window for the beam reporting evaluation process;

[0248] Close the time window for the beam reporting evaluation process associated with the fifth RS;

[0249] Restart the time window for the beam reporting evaluation process associated with the fifth RS;

[0250] Wherein, the change of the fifth RS includes at least one of the following:

[0251] The QCL RS corresponding to at least one of the first and second TCI states changes;

[0252] The QCL RS corresponding to at least one of the first and second TCI states changes;

[0253] The QCL RS corresponding to at least one TCI state changes;

[0254] The QCL RS corresponding to at least one TCI state changes;

[0255] The RS associated with the at least one reference signal resource set changes;

[0256] The RS associated with the at least one reference signal resource combination changes.

[0257] For example, the beam reporting evaluation process can be an evaluation process based on the terminal triggering beam reporting, which can also be called an event evaluation process, a trigger condition evaluation process, etc.

[0258] In this embodiment, if the fifth RS among the at least one first RS and the at least one second RS changes, the terminal can close / restart the counter or time window of the beam reporting evaluation process, which can improve the accuracy of the beam reporting evaluation.

[0259] In some embodiments, the at least one TCI state includes at least one of the following: joint TCI state, downlink TCI state.

[0260] In other alternative embodiments, the at least one TCI state includes an uplink TCI state.

[0261] In this embodiment, by defining the TCI state type in the at least one TCI state, the terminal can perform terminal-triggered beam reporting evaluation based on the appropriate TCI state type, which can improve the flexibility of beam reporting.

[0262] Figure 4 is a schematic flowchart of a wireless communication method 300 according to an embodiment of this application.

[0263] As shown in Figure 4, the wireless communication method 300 may include at least some of the following:

[0264] S301, the network-side device sends first information, the first information including at least one of the following: first indication information, second indication information; wherein, the first indication information is used to indicate the association relationship between at least one Transmission Configuration Indicator (TCI) state and at least one first reference signal (RS), and the second indication information is used to indicate the association relationship between at least one TCI state and at least one of the following: at least one set of reference signal resources for beam measurement, at least one combination of reference signal resources for beam measurement; the TCI state in the at least one TCI state is an indication TCI state or an active TCI state, the TCI states associated with different reference signal resources in the same set of reference signal resources are the same, and the TCI states associated with different reference signal resources in any combination of reference signal resources are different.

[0265] In this embodiment, the network-side device sends the first indication information or the second indication information to the terminal, enabling the terminal to determine the association between the at least one first RS and the at least one second RS. For example, the terminal can determine the target first RS among the at least one first RS and the second RS corresponding to the target first RS among the at least one second RS, thereby enabling the terminal to perform beam reporting evaluation based on at least one of the target first RS and the second RS corresponding to the target first RS.

[0266] In some embodiments, the at least one first RS includes at least one of the following:

[0267] The quasi-co-address reference signal QCL RS corresponding to each of the at least one TCI states;

[0268] The QCL RS corresponding to each TCI state in the at least one TCI state.

[0269] In some embodiments, the first information further includes at least one of the following:

[0270] Configuration information of the at least one reference signal resource set;

[0271] Configuration information of the at least one reference signal resource combination;

[0272] Configuration information for the triggering conditions used for beam reporting;

[0273] Information indicating the RS type of the first RS;

[0274] Information on the RS type of at least one second RS, wherein the at least one second RS is associated with the at least one set of reference signal resources or the at least one combination of reference signal resources.

[0275] In some embodiments, the at least one TCI state includes at least one of the following: joint TCI state, downlink TCI state.

[0276] It should be understood that the wireless communication method 300 includes a process for the network-side device to configure information to the terminal. The terminology involved is similar to that of method 200. Therefore, the specific content can be referred to the relevant description in method 200. To avoid repetition, it will not be repeated here.

[0277] The solution provided in this application will be described below with reference to specific embodiments.

[0278] Example 1:

[0279] In this embodiment, the terminal can implement event evaluation and reporting for different TRPs based on different reports. In addition to reusing the report configuration and event evaluation process of triggering reporting for a single TRP, the framework design is simple and has little impact on the protocol. It can also more flexibly implement the event evaluation process and reporting on a TRP-by-TRP basis.

[0280] Referring to Figure 5, the process of beam reporting by the terminal includes the following steps:

[0281] Step 1:

[0282] The terminal receives first information from the network side, the first information including configuration information triggered and reported by the terminal, the configuration information triggered and reported by the terminal including at least one of the following:

[0283] 1. Report the relevant configuration information of the associated triggering events.

[0284] The relevant configuration information includes, but is not limited to, the identifier of the event / condition, the preset number of times the event / condition is met, the relevant configuration information of the time window, or the threshold, etc.

[0285] 2. Report the set of measurement reference signals corresponding to the associated candidate beams.

[0286] Optionally, the number of measurement reference signal resource sets corresponding to the reported associated candidate beams is equal to 1.

[0287] Optionally, the set of measurement reference signals corresponding to the reported candidate beam can be a set of reference signals. For example, different sets of reference signals can be associated with different TCI states.

[0288] 3. First instruction information.

[0289] The first indication information is used to indicate the association between the reference signal corresponding to the beam being used by the terminal and at least one TCI state, and the first indication information is configured or indicated by the network side.

[0290] Optionally, the at least one TCI state is one or more of a plurality of (≥2) DL TCI states / joint TCI states indicated by the network, or one or more TCI states associated with a network-activated TCI code point associated with a plurality of (≥2) DL TCI states / joint TCI states.

[0291] For example, the first indication information can be used to indicate the reference signal and control resource set pool index (CORESETPoollindex) or the applied indicated TCI state corresponding to the beam being used by the terminal. For instance, when the first indication information indicates the applied indicated TCI state, it can specifically indicate that the applied indicated TCI state is the first applied TCI state or the second applied TCI state.

[0292] 4. Report the RS type corresponding to the associated measurement resources.

[0293] Optionally, the reported associated measurement resources include resources associated with the beam being used by the terminal.

[0294] Optional RS types, but not limited to CSI-RS, TRS, SSB, etc. used for BM.

[0295] Step 2:

[0296] Based on the first information, the terminal determines at least one of at least one first RS and at least one second RS for event / condition evaluation.

[0297] For example, the terminal may determine the first RS based on the first indication information, which may specifically include at least one of the following:

[0298] For example, the terminal can determine the first indication TCI state based on the first indication information, where the first RS is the QCL RS of the first indication TCI state or the QCL RS of the first indication TCI state (e.g., SSB).

[0299] Specifically, in the case of multi-DCI mTRP, the TCI state #1 is associated with the PDCCH indicating CORESETPOOlindex#0, and the TCI state #2 is associated with the PDCCH indicating CORESETPOOlindex#1. When the first indication information corresponds to CORESETPoolindex#0, the first indication TCI state is TCI state #1; otherwise, it is TCI state #2. Alternatively, the TCI state #1 associated with the PDCCH indicating CORESETPOOlindex#0 is the first indication TCI state, and the TCI state #2 associated with the PDCCH indicating CORESETPOOlindex#1 is the second indication TCI state. When the first indication information corresponds to the first indication TCI state, the first indication TCI state is TCI state #1; otherwise, it is TCI state #2.

[0300] Specifically, in the case of single-DCI mTRP, the TCI code point corresponding to the TCI field in the DCI contains {TCI state #1, TCI state #2}. TCI state #1, which appears earlier in the sequence, is the first indicating TCI state, and TCI state #2, which appears later in the sequence, is the second indicating TCI state. When the first indication information corresponds to the first indicating TCI state, the first indicating TCI state is TCI state #1; otherwise, it is TCI state #2.

[0301] For example, the terminal determines a first activated TCI state based on the first indication information, where the first RS is the QCL RS of the first activated TCI state or the QCL RS of the first activated TCI state (e.g., SSB), and the first activated TCI state is the activated TCI state with the Q highest measurement result among the activated TCI states.

[0302] Specifically, in the case of multi-DCI mTRP, the MAC CE containing CORESETPOOlindex#0 activates TCI states #1 to #4, and the MAC CE containing CORESETPOOlindex#1 activates TCI states #5 to #8. When the first indication information corresponds to CORESETPoolindex#0 / first, the first activated TCI state is one of TCI states #1 to #4. For example, the first activated TCI state and the first RS are determined by comparing the measurement results corresponding to the RSs of TCI states #1 to #4 respectively. Otherwise, the first activated TCI state and the first RS are determined in TCI states #5 to #8 according to the above method.

[0303] Specifically, in the single-DCI mTRP case, the MAC CE activates four TCI code points, where TCI code point #1: {TCI state #1, TCI state #2}, TCI code point #2: {TCI state #3, TCI state #4}, TCI code point #3: {TCI state #5, TCI state #6}, and TCI code point #4: {TCI state #7, TCI state #8}. The protocol stipulates that the TCI state appearing earlier in the sequence within each TCI code point is the first activated TCI state, and the TCI state appearing later in the sequence is the second activated TCI state. Therefore, when the first indication information corresponds to the first activated TCI state, the first activated TCI state is one of {TCI state #1, TCI state #3, TCI state #5, TCI state #7}. The first activated TCI state and the first RS are determined by comparing the measurement results corresponding to the first activated TCI state. Conversely, when the first activated TCI state is one of {TCI state #2, TCI state #4, TCI state #6, TCI state #8}, the first activated TCI state and the first RS are determined by comparing the measurement results corresponding to the first activated TCI state.

[0304] For example, the terminal can determine the RS type of the first RS based on the RS type contained in the measurement reference signal resource set corresponding to the candidate beam or the RS type corresponding to the reported associated measurement resource.

[0305] Optionally, when the set of measurement reference signal resources corresponding to the candidate beam is missing, the terminal determines the RS type of the first RS based on the RS type corresponding to the reported associated measurement resources.

[0306] Optionally, when the measurement reference signal resource set corresponding to the candidate beam is configured, the terminal determines the RS type of the first RS according to the type of RS contained in the measurement reference signal resource set corresponding to the candidate beam.

[0307] For example, the terminal can determine the second RS based on the measurement resources contained in the measurement reference signal resource set corresponding to the candidate beam.

[0308] Step 3:

[0309] For example, the terminal determines whether the triggering event associated with the report is met based on at least one of the measurement results of the first RS and the second RS. When the event is met, the beam reporting process is triggered.

[0310] The reported associated triggering events include at least one of the following:

[0311] At least one of the measurement results of the second RS is higher than the measurement result of the first RS by a certain threshold;

[0312] There exists at least one second RS, and the number of times its corresponding measurement result is higher than the measurement result of the first RS by a certain threshold within a preset time period is not less than a preset number;

[0313] The measurement result of the first RS is below a certain threshold;

[0314] Within a preset time period, the number of times the measurement result of the first RS is lower than a certain threshold is not less than a preset number.

[0315] Example 2:

[0316] In this embodiment, by having one report correspond to the event evaluation and reporting process of two TRPs, independent event evaluation of multiple TRPs can be achieved, while reducing reporting resource overhead and reporting latency.

[0317] Referring to Figure 6, the process of beam reporting by the terminal includes the following steps:

[0318] Step 1:

[0319] The terminal receives first information from the network side, the first information including configuration information triggered and reported by the terminal, the configuration information triggered and reported by the terminal including at least one of the following:

[0320] 1. Report the relevant configuration information of the associated triggering events.

[0321] The relevant configuration information includes, but is not limited to, the identifier of the event / condition, the preset number of times the event / condition is met, the relevant configuration information of the time window, or the threshold, etc.

[0322] Optionally, the configuration information related to the reported triggering events may include two preset counts of events / conditions being met, configuration information for two time windows, or two thresholds. For example, different evaluation parameters can be configured for each TRP event evaluation to improve the flexibility of network configuration and event evaluation.

[0323] 2. At least two reported associated candidate beam sets corresponding to measurement reference signal resources.

[0324] Optionally, the set of measurement reference signals corresponding to the reported candidate beam can be a set of reference signals. For example, different sets of reference signals can be associated with different TCI states.

[0325] 3. Report the RS type corresponding to the associated measurement resource.

[0326] Optionally, the reported associated measurement resources include resources associated with the beam being used by the terminal.

[0327] Optional RS types, but not limited to CSI-RS, TRS, SSB, etc. used for BM.

[0328] Step 2:

[0329] Based on the first information, the terminal determines at least one of at least one first RS and at least one second RS for event / condition evaluation.

[0330] For example, when the set of measurement reference signal resources corresponding to the reported associated candidate beam is default, the at least one first RS is either a QCL resource RS (e.g., CSI-RS) of the at least one TCI state or a QCL RS (e.g., SSB) of the QCL RS of the at least one TCI state. Optionally, the at least one TCI state is a DL TCI state / joint TCI state among multiple (≥2) DL TCI states / joint TCI states indicated by the network.

[0331] Specifically, taking Event 1 as an example, in the case of multi-DCI mTRP, the TCI state #1 is indicated by the PDCCH associated with CORESETPOOlindex#0, and the TCI state #2 is indicated by the PDCCH associated with CORESETPOOlindex#1. Since Event 1 only needs to evaluate the beam quality indicating the TCI state, the measurement and reporting of candidate beams can be unnecessary, and the corresponding configuration can be left blank. Since there are two indicating TCI states that need to be evaluated, one approach is to evaluate them separately and independently, that is, to determine two first RSs based on the two indicating TCI states respectively. The terminal evaluates whether the conditions are met based on the measurement results of the two first RSs respectively. When the measurement result of at least one first RS meets the triggering condition of Event 1, the terminal reporting process is triggered.

[0332] Specifically, taking Event 1 as an example, in the case of single-DCI mTRP, the TCI code point corresponding to the TCI field in DCI contains {TCI state #1, TCI state #2}. The processing method is the same as that of multi-DCI mTRP. The terminal determines two first RSs based on TCI state #1 and TCI state #2 respectively. The terminal evaluates whether the conditions are met based on the measurement results of the two first RSs respectively. When the measurement result of at least one first RS meets the triggering condition of Event 1, the terminal reporting process is triggered.

[0333] Optionally, when the configuration information related to the reported associated triggering event includes two preset number of times the event / condition is met, two time window configuration information, or two thresholds, the terminal will execute the above two evaluation processes according to the two configurations (including but not limited to two preset number of times the event / condition is met, two time window configuration information, or two thresholds).

[0334] Optionally, when the configuration information related to the reported associated triggering event includes a preset number of times the event / condition is met, configuration information related to a time window, or a threshold, the terminal performs event evaluation on the two first RSs based on the aforementioned event evaluation criterion. For example, it determines whether the two first RSs meet the conditions within the same time window.

[0335] For example, when there are at least two sets of measurement reference signal resources corresponding to the reported associated candidate beams, the terminal determines the second RS based on the measurement resources contained in the at least two sets of measurement reference signal resources corresponding to the reported associated candidate beams, and determines the first RS associated with the at least two sets of measurement reference signal resources corresponding to the reported associated candidate beams respectively.

[0336] Specifically, the first RS associated with the measurement reference signal resource sets corresponding to the at least two reported candidate beams is a QCL RS indicating the TCI state or a QCL RS of a QCL RS associated with the measurement reference signal resource sets corresponding to the at least two reported candidate beams. Specifically, the first measurement reference signal resource set #1 is associated with the TCI state or the TCI state associated with CORESETPoolindex#0 and corresponds to the candidate beam, and the second measurement reference signal resource set #2 is associated with the TCI state or the TCI state associated with CORESETPoolindex#1 and corresponds to the candidate beam.

[0337] Specifically, the first RS associated with the measurement reference signal resource sets corresponding to the at least two reported candidate beams is the QCL RS or the QCL RS of the active TCI state associated with the measurement reference signal resource sets corresponding to the at least two reported candidate beams. Among all active TCI code points, the active TCI state ranked first or the active TCI state associated with CORESETPoolindex#0 is associated with / corresponding to the measurement reference signal resource set #1 of the candidate beams, and the active TCI state ranked last or the active TCI state associated with CORESETPoolindex#1 is associated with / corresponding to the measurement reference signal resource set #2 of the candidate beams.

[0338] Optionally, the active TCI states associated with the measurement reference signal resource sets corresponding to the at least two reported associated candidate beams can be the Q-th highest active TCI state of the measurement result. For example, the Q-th highest active TCI state of the measurement result is determined for each TRP. Alternatively, the Q-th highest TCI code point of the measurement result can be determined first, and then the active TCI states of TRP#1 and TRP#2 can be determined based on the two TCI states contained in the TCI code point.

[0339] For example, the active TCI state associated with the measurement reference signal resource sets corresponding to the at least two reported candidate beams can be determined according to at least one of the following methods:

[0340] 1. The Q-highest active TCI state of the measurement result in the active TCI state of the measurement reference signal resource set #1 corresponding to the candidate beam;

[0341] 2. The Q-highest active TCI state of the measurement result in the active TCI state of the measurement reference signal resource set #2 corresponding to the candidate beam;

[0342] 3. Among all active TCI code points, the Q-highest TCI code point of the measurement result is associated with the active TCI state of the measurement reference signal resource set #1 and the measurement reference signal resource set #2 of the candidate beam, respectively.

[0343] Among all activated TCI code points, the Q-th highest TCI code point in the measurement result can be determined according to at least one of the following methods:

[0344] The lowest measured RS among all TCI code points corresponding to all TCI states, the Q-highest TCI code point.

[0345] The highest-measured RS value for all TCI states among all TCI code points is the Q-highest TCI code point.

[0346] The Q-highest TCI code point is the sum of the RS measurements corresponding to all TCI states among all TCI code points.

[0347] For example, the terminal can determine the RS type of the first RS based on the RS type contained in the measurement reference signal resource set corresponding to the candidate beam or the RS type corresponding to the reported associated measurement resource;

[0348] Optionally, when the set of measurement reference signal resources corresponding to the candidate beam is missing, the terminal determines the RS type of the first RS based on the RS type corresponding to the reported associated measurement resources.

[0349] Optionally, when the measurement reference signal resource set corresponding to the candidate beam is configured, the terminal determines the RS type of the first RS according to the type of RS contained in the measurement reference signal resource set corresponding to the candidate beam.

[0350] Step 3:

[0351] Once the measurement reference signal resource set associated with or corresponding to the first RS of the at least two candidate beams is determined, the terminal performs event evaluation based on the measurement reference signal resource set of each candidate beam and its associated / corresponding first RS. When at least one second RS and its corresponding first RS satisfy the triggering event, the beam reporting process is triggered.

[0352] The reported associated triggering events include at least one of the following:

[0353] At least one of the measurement results of the second RS is higher than the measurement result of the first RS by a certain threshold;

[0354] There exists at least one second RS, whose measurement result is higher than a certain threshold of the measurement result of the first RS a number of times within a preset time period is not less than a preset number.

[0355] Optionally, during the event evaluation process, when the first RS or the second RS changes, the terminal performs at least one of the following operations:

[0356] Reset the count values ​​of all event evaluation processes associated with the report to zero;

[0357] Clear the count value in the event evaluation process associated with the changed first RS or second RS to zero;

[0358] Close the time window for all event evaluation processes associated with the report;

[0359] Restart the time window for the evaluation process of all events associated with the aforementioned report;

[0360] Close the time window for the event evaluation process associated with the changed first RS or second RS;

[0361] Restart the time window for the event evaluation process associated with the first or second RS that has changed.

[0362] Wherein, the change of the first RS or the second RS includes at least one of the following:

[0363] The QCL RS or the QCL RS of at least one of the at least one TCI states changes;

[0364] The RS associated with the measurement reference signal resource set corresponding to the reported candidate beam changes.

[0365] Example 3:

[0366] In this embodiment, one report corresponds to the joint event evaluation process and reporting of two TRPs. Reporting is only triggered when the joint evaluation results based on the two TRPs meet the event triggering conditions. Compared to Embodiments 1 and 2, the reporting triggering conditions in this embodiment are more stringent, thereby reducing the number of reports and thus reducing reporting overhead.

[0367] Referring to Figure 7, the process of beam reporting by the terminal includes the following steps:

[0368] Step 1:

[0369] The terminal receives first information from the network side, the first information including configuration information triggered and reported by the terminal, the configuration information triggered and reported by the terminal including at least one of the following:

[0370] 1. Report the relevant configuration information of the associated triggering events.

[0371] The relevant configuration information includes, but is not limited to, the identifier of the event / condition, the preset number of times the event / condition is met, the relevant configuration information of the time window, or the threshold, etc.

[0372] Optionally, the configuration information related to the reported triggering events may include two preset counts of events / conditions being met, configuration information for two time windows, or two thresholds. For example, different evaluation parameters can be configured for each TRP event evaluation to improve the flexibility of network configuration and event evaluation.

[0373] 2. At least two reported associated candidate beam sets corresponding to measurement reference signal resources.

[0374] Optionally, the set of measurement reference signals corresponding to the reported candidate beam can be a set of reference signals. For example, different sets of reference signals can be associated with different TCI states.

[0375] 3. Report the RS type corresponding to the associated measurement resource.

[0376] Optionally, the reported associated measurement resources include resources associated with the beam being used by the terminal.

[0377] Optional RS types, but not limited to CSI-RS, TRS, SSB, etc. used for BM.

[0378] Step 2:

[0379] Based on the first information, the terminal determines at least one of at least one first RS and at least one second RS for event / condition evaluation.

[0380] For example, when the reported associated triggering event / condition is event 1, the first RS is a QCL resource RS of at least one TCI state (e.g., CSI-RS) or a QCL RS of at least one TCI state (e.g., SSB).

[0381] For example, the at least one TCI state is a DL TCI state / joint TCI state determined by the terminal from a plurality of (≥2) DL TCI states / joint TCI states indicated by the network according to a preset rule; the preset rule includes at least one of the following:

[0382] 1. The measurement results of the associated RS are at their maximum / highest. That is, a report is only made when the maximum value is below a certain threshold, thus reducing beam reporting and lowering reporting overhead while ensuring that at least one beam can transmit data.

[0383] 2. The associated RS measurement result is the minimum / lowest. This means that the minimum value is used as a reference for reporting, ensuring timely reporting so that the network can update the beam as quickly as possible. This guarantees the high quality of the beam used for data transmission, ensuring high-speed and reliable data transmission.

[0384] For example, the at least one TCI state is a network indication of the plurality of (≥2) DL TCI states / joint TCI states.

[0385] Furthermore, the number of the first RS is greater than 1, and event 1 is defined as one of the following:

[0386] The sum of the measurement results of the first RS is less than a preset value;

[0387] The weighted average of the measurement results of the first RS is less than a preset value;

[0388] The linear average value of the measurement results of the first RS is less than the preset value.

[0389] When the reported associated triggering event / condition is event 2, the following two situations exist:

[0390] Scenario 1:

[0391] For example, the at least one first RS is a QCL resource RS of at least one TCI state (e.g., CSI-RS) or a QCL RS of the at least one TCI state (e.g., SSB).

[0392] Wherein, the at least one TCI state is a TCI state determined by the terminal from multiple (≥2) DL TCI states / joint TCI states indicated by the network according to a preset rule; the preset rule includes at least one of the following:

[0393] 1. The measurement results of the associated RS are at their maximum / highest. That is, a report is only made when the maximum value is below a certain threshold, thus reducing beam reporting and lowering reporting overhead while ensuring that at least one beam can transmit data.

[0394] 2. The associated RS measurement result is the minimum / lowest. This means that the minimum value is used as a reference for reporting, ensuring timely reporting so that the network can update the beam as quickly as possible. This guarantees the high quality of the beam used for data transmission, ensuring high-speed and reliable data transmission.

[0395] Wherein, the at least one second RS includes at least one of the following:

[0396] 1. The at least one second RS is one of the measurement reference signal resource sets of at least two candidate beams that are reported and associated;

[0397] 2. The at least one second RS is one RS in the set of measurement reference signal resources for at least one candidate beam that the terminal has reported and associated according to a preset rule, specifically including at least one of the following:

[0398] The maximum value of the measurement result can be reported in a timely manner so that the network can update the beam as soon as possible, ensuring the high quality of the beam used for data transmission, and thus ensuring high-speed and reliable data transmission.

[0399] The minimum measurement result is reported only when the minimum value of the candidate beam is higher than the quality of the currently used beam than a certain threshold, thus reducing beam reporting and lowering reporting overhead.

[0400] Furthermore, the number of the first RS and the number of the second RS are both equal to 1. The event 2 is defined as: at least one second RS has a measurement result higher than a certain threshold of the measurement result of the first RS; or at least one second RS has a measurement result higher than a certain threshold of the measurement result of the first RS a number of times within a preset time period.

[0401] Scenario 2:

[0402] For example, the at least one first RS is a QCL resource RS (e.g., CSI-RS) of at least one TCI state or a QCL RS (e.g., SSB) of the at least one TCI state. The at least one TCI state is a network indication of the plurality (≥2) DL TCI states / joint TCI states.

[0403] Wherein, the at least one second RS is an RS in each measurement reference signal resource set in the measurement reference signal resource set of at least one candidate beam that is reported and associated.

[0404] Furthermore, if the number of RSs corresponding to the first RS is greater than 1, and the number of RSs corresponding to the second RS is greater than 1, then event 2 is defined as one of the following:

[0405] There exists at least one second RS whose first measurement result is higher than the measurement result of the first RS by a certain threshold;

[0406] There exists at least one second RS, and the number of times the measurement result of the second RS is higher than the measurement result of the first RS by a certain threshold within a preset time period is not less than a preset number.

[0407] The measurement result of the first RS includes at least one of the following:

[0408] The sum of the measurement results of all RSs corresponding to the first RS;

[0409] The weighted average of the measurement results of all RSs corresponding to the first RS;

[0410] The linear average of the measurement results of all RSs corresponding to the first RS.

[0411] The measurement result of the second RS includes at least one of the following:

[0412] The sum of the measurement results of all RSs corresponding to the second RS;

[0413] The weighted average of the measurement results of all RSs corresponding to the second RS;

[0414] The linear average of the measurement results of all RSs corresponding to the second RS.

[0415] When the reported associated triggering event / condition is event 7, the following two situations exist:

[0416] Scenario 1:

[0417] For example, the at least one first RS is a QCL resource RS (e.g., CSI-RS) of at least one TCI state or a QCL RS (e.g., SSB) of the at least one TCI state, and the at least one TCI state is a TCI state determined by the terminal from a plurality of (≥2) DL TCI states / joint TCI states corresponding to the Q-highest TCI code point in the network-activated TCI code points according to a preset rule; the preset rule includes at least one of the following:

[0418] 1. The measurement results of the associated RS are at their maximum / highest value. That is, the data is only reported when the maximum value is below a certain threshold. This reduces beam reporting and lowers reporting overhead, while ensuring that at least one beam can transmit data.

[0419] 2. The measurement result of the associated RS is the minimum / lowest, that is, the minimum value is reported. This allows for timely reporting so that the network can update the beam as soon as possible, ensuring the high quality of the beam used for data transmission, and thus ensuring high-speed and reliable data transmission.

[0420] Among all activated TCI code points, the Q-th highest TCI code point in the measurement result can be determined according to at least one of the following methods:

[0421] The lowest measurement result of RS for all TCI states among all TCI code points is the Q-highest TCI code point.

[0422] The highest measurement result of RS for all TCI states among all TCI code points is the Q-highest TCI code point.

[0423] The Q-highest TCI code point is the sum of the RS measurements corresponding to all TCI states among all TCI code points.

[0424] It should be understood that for sDCI, the activated TCI code point in the MAC CE corresponds to two TCI states; however, for mDCI, a single activated TCI code point in a MAC CE has only one TCI state. In this case, the terminal combines the activated TCI states according to the order of the TCI states in multiple activated TCI code points in the MAC CEs, thus achieving one TCI code point corresponding to two TCI states. For example: for MAC CE #1 of CORESETPoolindex#0 activating {TCI states #1~4}, and for MAC CE #2 of CORESETPoolindex#1 activating {TCI states #5~8}, then according to the arrangement order of the TCI states in the MAC CE, TCI code point #1 corresponds to TCI states #1 and #5, TCI code point #2 corresponds to TCI states #2 and #6, TCI code point #3 corresponds to TCI states #3 and #7, and TCI code point #4 corresponds to TCI states #1 and #8. Furthermore, when the number of activated TCI states in the two MAC CEs is different, the TCI code point that is later in the sequence corresponds to a TCI state, and the terminal will determine the first RS based on the TCI state.

[0425] For example, the at least one second RS includes at least one of the following:

[0426] 1. The at least one second RS is one of the measurement reference signal resource sets of at least two candidate beams that are reported and associated;

[0427] 2. The at least one second RS is one RS in the set of measurement reference signal resources for at least one candidate beam that the terminal has reported and associated according to a preset rule, specifically including at least one of the following:

[0428] The maximum value of the measurement result can be reported in a timely manner so that the network can update the beam as soon as possible, ensuring the high quality of the beam used for data transmission, and thus ensuring high-speed and reliable data transmission.

[0429] The minimum measurement result is reported only when the minimum value of the candidate beam is higher than the quality of the currently used beam than a certain threshold, thus reducing beam reporting and lowering reporting overhead.

[0430] Furthermore, the number of the first RS and the number of the second RS are both equal to 1. Event 7 is defined as: at least one second RS has a measurement result higher than a certain threshold of the measurement result of the first RS; or at least one second RS has a measurement result higher than a certain threshold of the measurement result of the first RS a number of times within a preset time period.

[0431] Scenario 2:

[0432] For example, the at least one first RS is a QCL resource RS (e.g., CSI-RS) of at least one TCI state or a QCL RS (e.g., SSB) of the QCL RS of the at least one TCI state. The at least one TCI state is a plurality of (≥2) DL TCI states / joint TCI states corresponding to the Q-highest TCI code point in the measurement results among the network-activated TCI code points.

[0433] Wherein, the at least one second RS is an RS in each measurement reference signal resource set in the measurement reference signal resource set of at least one candidate beam that is reported and associated.

[0434] Furthermore, if the number of RSs corresponding to the first RS is greater than 1, and the number of RSs corresponding to the second RS is greater than 1, then event 2 is defined as one of the following:

[0435] There exists at least one second RS whose first measurement result is higher than the measurement result of the first RS by a certain threshold;

[0436] There exists at least one second RS, and the number of times the measurement result of the second RS is higher than the measurement result of the first RS by a certain threshold within a preset time period is not less than a preset number.

[0437] The measurement result of the first RS includes at least one of the following:

[0438] The sum of the measurement results of all RSs corresponding to the first RS;

[0439] The weighted average of the measurement results of all RSs corresponding to the first RS;

[0440] The linear average of the measurement results of all RSs corresponding to the first RS.

[0441] The measurement results of the second RS include at least one of the following:

[0442] The sum of the measurement results of all RSs corresponding to the second RS;

[0443] The weighted average of the measurement results of all RSs corresponding to the second RS;

[0444] The linear average of the measurement results of all RSs corresponding to the second RS.

[0445] For example, the terminal can determine the RS type of the first RS based on the RS type contained in the measurement reference signal resource set corresponding to the candidate beam or the RS type corresponding to the reported associated measurement resource;

[0446] Optionally, when the set of measurement reference signal resources corresponding to the candidate beam is missing, the terminal determines the RS type of the first RS based on the RS type corresponding to the reported associated measurement resources.

[0447] Optionally, when the measurement reference signal resource set corresponding to the candidate beam is configured, the terminal determines the RS type of the first RS according to the type of RS contained in the measurement reference signal resource set corresponding to the candidate beam.

[0448] For example, during the event evaluation process, when the first RS or the second RS changes, the terminal performs at least one of the following operations:

[0449] Reset the count values ​​of all event evaluation processes associated with the report to zero;

[0450] Close the time window for all event evaluation processes associated with the report;

[0451] Restart the time window for the evaluation process of all events associated with the report.

[0452] Wherein, the change of the first RS or the second RS includes at least one of the following:

[0453] The QCL RS or the QCL RS of at least one of the at least one TCI states changes;

[0454] The RS associated in the measurement reference signal resource set corresponding to the reported candidate beam changes;

[0455] The RS in the measurement reference signal resource combination of the reported associated candidate beam changes.

[0456] Example 4:

[0457] In this embodiment, for mTRP which includes uplink-only (UL-only) TRP, the terminal is able to perform beam reporting evaluation in the mTRP scenario, that is, to realize beam reporting based on terminal triggering, thereby improving beam reporting performance.

[0458] For example, the terminal determines whether the triggering event associated with the report is met based on at least one of the measurement results of the first RS and the second RS. When the event is met, the beam reporting process is triggered.

[0459] Referring to Figure 8, since there is only one DL TCI state in the TCI activation and indication under mTRP containing UL-only TRP, if the terminal triggers the report only for the downlink, then for events 1 and 2, the first RS is determined based on the network-indicated DL TCI state, that is, it is either the QCL RS of the network-indicated DL TCI state or the QCL RS of the network-indicated DL TCI state; for event 7, it is determined based on the Q-highest TCI state of the measurement result among the network-activated DL TCI states, that is, it is either the QCL RS of the Q-highest TCI state of the measurement result among the network-activated DL TCI states or the QCL RS of the Q-highest TCI state of the measurement result among the network-activated DL TCI states.

[0460] The second RS is determined based on the set of measurement reference signal resources corresponding to the reported associated candidate beams; specifically, the second RS is the RS associated with the set of measurement reference signal resources corresponding to the reported associated candidate beams.

[0461] It should be noted that although there is only one DL TCI state, if the RS of the TCI-UL state corresponding to the UL-only TRP is an SSB or CSI-RS, based on beam heterogeneity, the terminal can determine the uplink beam quality and whether switching is needed based on the measured RS. Therefore, the first RS can be the QCL RS or the QCL RS of the QCL RS corresponding to the indicator TCI-UL state or the active TCI-UL state associated with the UL-only TRP (e.g., the TCI-UL state with the highest Q measurement result). The corresponding second RS is determined based on the measurement reference signal resource set corresponding to the reported associated candidate beam; specifically, the second RS is the RS associated with the measurement reference signal resource set corresponding to the reported associated candidate beam.

[0462] Example 5:

[0463] In this embodiment, for mTRPs that include uplink-only (UL-only) TRPs, the terminal can implement event evaluation and reporting for different TRPs based on different reports. In addition to reusing the report configuration and event evaluation process for triggering reporting of a single TRP, the framework design is simple and has little impact on the protocol. It can also more flexibly implement the event evaluation process and reporting on a TRP-by-TRP basis.

[0464] Referring to Figure 9, the two event evaluation processes mentioned above are performed separately and can be associated with different reporting configurations. The specific implementation of beam reporting can be found in the description of Embodiment 1. The difference is that the at least one TCI state can be a DL TCI state or a TCI-UL state. To avoid repetition, it will not be described again here.

[0465] Example 6:

[0466] In this embodiment, one report corresponds to the joint event evaluation process and reporting of two TRPs. Reporting is only triggered when the joint evaluation results based on the two TRPs meet the event triggering conditions. Compared to Embodiments 1 and 2, the reporting triggering conditions in this embodiment are more stringent, thereby reducing the number of reports and thus reducing reporting overhead.

[0467] Referring to Figure 10, the two event evaluation processes mentioned above are performed separately, but they can be associated with the same reporting configuration. The specific implementation of beam reporting can be found in the description of Embodiment 2. The difference is that the at least one TCI state can be a DL TCI state or a TCI-UL state. To avoid repetition, it will not be described again here.
