[0049] In order to facilitate understanding of the technical solutions provided in the present application, the main technical concepts related to the embodiments of the present application are briefly described below.

[0050] LTM measurement configuration and reporting configuration:

[0051] In R18, LTM (L1 / L2 Triggered Mobility) is introduced. Specifically, the serving base station determines the target cell based on the L1 / L2 measurement result of the UE, and triggers the UE to switch the primary cell or the primary secondary cell (or the primary cell group or the secondary cell group) to the target cell (or the target cell group) using the MAC layer control element (MAC Control Element, MAC CE). As shown in FIG. 2, FIG. 2 shows a schematic diagram of the measurement configuration of LTM. In the LTM process, the network side device will send a radio resource control (Radio Resource Control, RRC) message in advance, which contains multiple candidate configuration information and multiple LTM channel state information (Channel State Information, CSI) resource configuration information. Each LTM CSI resource configuration information includes one or more reference signal (Reference Signals, RS) resources of one or more LTM candidate cells, that is, one or more candidate configuration IDs and corresponding synchronization signal block index (Synchronization Signal Block index, SSB index). The candidate configuration ID associated candidate configuration has detailed RS configuration information of the candidate cell, including the frequency point, subcarrier spacing, period, time domain position and power related information of the RS. The UE can find the specific RS configuration information in the candidate configuration through the candidate configuration ID and the SSB index, so as to measure the RS and obtain the L1 measurement result of the RS of the candidate cell.

[0052] In addition, one or more LTM-related CSI reporting configurations are included in the serving cell configuration of the UE, and each CSI reporting configuration includes the following information:

[0053] LTM CSI reporting configuration identifier;

[0054] LTM CSI resource configuration identifier;

[0055] LTM reporting configuration type, including periodic reporting / semi-persistent reporting based on a physical uplink control channel (PUCCH) and corresponding reporting resources;

[0056] LTM reporting content, including the number of candidate cells for LTM CSI reporting and the number of RSs reported for each cell.

[0057] Each LTM CSI reporting configuration is associated with one LTM CSI resource configuration information, and the UE uses the reporting type and reporting resources in the LTM CSI reporting configuration to report the L1 measurement results of the N RSs of the M candidate cells in the LTM CSI resource configuration information.

[0058] L3 measurement configuration and reporting configuration:

[0059] The network configures the UE in an RRC connected state (RRC_CONNECTED) to perform L3 (layer 3) measurement, and the network configures the UE to perform reporting according to the measurement configuration or to evaluate whether the handover condition is met according to the measurement results. As shown in FIG. 3, FIG. 3 shows a schematic diagram of an L3 measurement configuration. Specifically, the measurement configuration information includes the following parameters:

[0060] Measurement object (MO), one MO indicates the time-frequency location of the RS to be measured, the NW configures multiple cells associated with the MO and the cell-specific bias value, and each MO is associated with a measObjectId.

[0061] Reporting configuration, each reporting configuration includes: reporting criteria, which is used to trigger the UE to send measurement reporting, and can be periodic reporting or event-triggered reporting; RS type, which is used to indicate which RS the UE uses to derive L3 measurement results; reporting format, i.e., the parameters (e.g., reference signal received power RSRP) included in the measurement reporting; in addition, the reporting configuration can also include other related information (e.g., the maximum number of cells reported by the UE and the maximum number of beams reported for each cell).

[0062] Measurement identity, each measurement identity is associated with one measurement object and one reporting configuration. By configuring multiple measurement identities, multiple MOs can be associated with one reporting configuration, or multiple reporting configurations can be associated with one MO.

[0063] Quantity configuration, which defines the filtering configuration parameters for all event evaluation and related reporting, as well as periodic measurement reporting.

[0064] Measurement gap, the period for UE to perform measurement.

[0065] For the MO associated with periodic and event triggered reporting of L3, when UE performs L3 measurement on the MO, UE decides whether to perform measurement based on SSB or CSI-RS according to the reference signal type (RS-type) in the reporting configuration associated with this MO, and decides to perform measurement of reference signal receiving power (RSRP), reference signal received quality (RSRQ) or signal to interference plus noise ratio (SINR) according to the reporting format in the reporting configuration. If S-MeasureConfig is included in the measurement configuration, when the quality of the serving cell is lower than the threshold value associated with S-MeasureConfig, UE can calculate L3 measurement based on the MO associated with non-serving cell.

[0066] In summary, L3 measurement configuration can support event triggered measurement reporting, i.e. measurement reporting will only be performed when the pre-defined measurement event is met, which can reduce unnecessary reporting. However, LTM measurement reporting does not support event triggered measurement reporting. Since the measurement of LTM is usually beam level measurement, after introducing the event triggered measurement reporting mechanism, how to correctly trigger the event and how to correctly reflect the measurement result of the cell through beam level measurement, the related technology does not give a solution.

[0067] Therefore, the embodiment of the present application provides a configuration information sending method, an LTM measurement method, a terminal and a network side device. The configuration information sending method comprises: a network side device sending measurement related configuration information to a terminal, wherein the measurement related configuration information is used for performing event triggered beam measurement reporting or conditional LTM, and the measurement related configuration information comprises at least one of the following parameters: a beam related parameter; and an event related parameter. In this way, the measurement related configuration information introduces a measurement configuration mechanism for LTM, and the network side device correctly configures the event triggered measurement configuration in LTM to the UE by sending the measurement related configuration information to the UE, so that the UE can accurately and timely perform the event triggered beam measurement reporting or conditional LTM according to the measurement related configuration information, thereby avoiding the problem that the network side device cannot obtain a suitable measurement result due to inaccurate or delayed measurement reporting, and further affecting the subsequent handover process.

[0068] The configuration information sending method, the LTM measurement method, the terminal and the network side device provided by the embodiment of the present application will be described in detail in combination with the drawings and some embodiments and application scenarios.

[0069] In order to facilitate understanding of the present application, the trigger events for UE triggered beam measurement reporting or conditional LTM are exemplified.

[0070] Event 1: when the measurement result of a first beam of a serving cell >= a first threshold;

[0071] Event 2: when the measurement result of the first beam of the serving cell <= a second threshold;

[0072] Event 3: when the measurement result of a second beam of a candidate cell >= the measurement result of the first beam of the serving cell, and a difference value >= a first offset value;

[0073] Event 4: when the measurement result of the second beam of the candidate cell >= a third threshold, and the difference value >= a second offset value;

[0074] Event 5: when the measurement result of the first beam of the serving cell <= a fourth threshold and the measurement result of the second beam of the candidate cell >= a fifth threshold.

[0075] The second beam is a beam with the best measurement result in one or more candidate cells, and specifically can be at least one of the following:

[0076] A-1 item: a beam with the best RSRP measurement result, or N beams with the best RSRP measurement result;

[0077] A-2 item: a beam with the best RSRQ measurement result, or N beams with the best RSRQ measurement result;

[0078] A-3: one beam with the best SINR measurement result, or N beams with the best SINR measurement result;

[0079] In the embodiments of the present application, the best beam in terms of measurement result refers to the best beam in terms of quality based on one or more candidate cells configured for the terminal to perform measurement, and the quality of the beam can be determined by RSRP measurement result, RSRQ measurement result and SINR measurement result. For multiple candidate cells, the relevant beam measurement configuration can be associated with the same event configuration (i.e., the same event-related parameters), and therefore, for multiple beams of multiple candidate cells, the best beam in terms of measurement result is the best beam in terms of measurement result across multiple candidate cells, rather than the best beam in terms of measurement result of a certain candidate cell.

[0080] In some embodiments, the second beam can also be at least one of the following in the one or more candidate cells:

[0081] A-4: the best one beam exceeding a preset threshold value;

[0082] A-5: the best N beams exceeding a preset threshold value;

[0083] A-6: any one beam exceeding a preset threshold value;

[0084] A-7: any N beams exceeding a preset threshold value;

[0085] A-8: any one or N beams in the measurement resource configuration information, wherein the measurement resource refers to the time-frequency domain resource used for measurement;

[0086] A-9: any one or N beams exceeding the threshold in the measurement resource configuration information.

[0087] The first beam can be at least one of the following in the serving cell:

[0088] B-1: one or N beams with the best RSRP measurement result, or one or N beams with the best RSRQ measurement result, or one or N beams with the best SINR measurement result;

[0089] B-2: one or more beams associated with the indicated TCI state;

[0090] B-3: one or more beams with the TCI state in the active state;

[0091] B-4: the beam currently used by the terminal.

[0092] In the embodiments of the present application, the UE can determine whether the triggering condition of the triggering event (for example, event 4) is met through the measurement result of the second beam determined according to the A-1 to A-9, or determine whether the triggering condition of the triggering event (for example, event 1) is met through the measurement result of the first beam determined according to the B-1 to B-4, or determine whether the triggering condition of the triggering event (for example, event 3) is met through the measurement result of the second beam determined according to the A-1 to A-9 and the measurement result of the first beam determined according to the B-1 to B-4.

[0093] In the first aspect of the embodiments of the present application, a configuration information sending method is provided, the method is applied to a network side device, referring to the embodiment flow chart of the configuration information sending method provided by the present application shown in FIG. 4, the method can include the following steps:

[0094] Step S410: The network side device sends measurement related configuration information to the terminal, the measurement related configuration information is used for event triggered beam measurement reporting or condition based layer 1 / layer 2 cross cell mobility mechanism LTM, and the measurement related configuration information includes at least one type of parameter:

[0095] The parameter related to the beam;

[0096] The parameter related to the event.

[0097] In the embodiments of the present application, the network side device can be the core network device or the access network device 12 in FIG. 1, and the terminal can be the terminal 11 in FIG. 1. For examples of the network side device 12 and the terminal 11, please refer to the foregoing description, which will not be repeated here.

[0098] The parameter related to the beam refers to the configuration parameter related to the beam, and the beam can be the beam of the current serving cell of the UE or the beam of one or more candidate cells, and different beams correspond to different parameters related to the beam; for example, beam 1 and beam 2 correspond to different parameters related to the beam. The parameter related to the event refers to the configuration parameter related to the triggering event, and different triggering events correspond to different parameters related to the event. For example, the event 1 and the event 2 correspond to different parameters related to the event.

[0099] The network-side device sends measurement-related configuration information. In some embodiments, the network-side device sends the beam-related parameters and the event-related parameters through one measurement-related configuration information. In other embodiments, the network-side device sends the beam-related parameters through one measurement-related configuration information and the event-related parameters through another measurement-related configuration information. When the network-side device sends the beam-related parameters and the event-related parameters through two measurement-related configuration information, the two measurement-related configuration information are associated so that the UE can perform the event-triggered beam measurement reporting or conditional LTM based on the beam-related parameters and the event-related parameters, where the association of the two measurement-related configuration information can be through resource configuration identification (resource config id) or through report configuration identification (report id).

[0100] The measurement-related configuration information is used by the terminal to perform the event-triggered beam measurement reporting or conditional LTM, where the event-triggered beam measurement reporting refers to that the UE reports the corresponding measurement results when the measurement results of the beams meet the trigger conditions of the trigger events, and the event-triggered conditional LTM refers to that the UE performs the conditional LTM based on the measurement results when the measurement results meet the trigger conditions of the trigger events. In some embodiments, the measurement-related configuration information is used by the terminal to perform the event-triggered conditional reconfiguration.

[0101] In the embodiments of the present application, the network-side device sends measurement-related configuration information, which includes at least one of the following parameters: beam-related parameters and event-related parameters. In this way, the measurement-related configuration information introduces a measurement configuration mechanism for LTM, and the network-side device correctly configures the measurement configuration of the event trigger in LTM to the UE by sending the measurement-related configuration information to the UE, so that the UE can accurately and timely perform the event-triggered beam measurement reporting or conditional LTM according to the measurement-related configuration information, thereby avoiding the situation that the network-side device cannot obtain appropriate measurement results due to inaccurate or delayed measurement reporting, and further affecting the subsequent handover process.

[0102] Correspondingly, after the network-side device sends the measurement-related configuration information, the terminal performs the following steps:

[0103] Step C1: The terminal receives the measurement-related configuration information sent by the network-side device, and the measurement-related configuration information includes at least one of the following parameters: beam-related parameters; event-related parameters.

[0104] Step C2: The terminal performs event-triggered beam measurement based on the measurement-related configuration information to obtain the measurement results of the beams.

[0105] In a case where the measurement result of the beam satisfies a trigger condition of the trigger event corresponding to the measurement-related configuration information, the terminal triggers reporting of the measurement result or performs the conditional LTM.

[0106] In the embodiments of the present application, the network-side device configures the measurement configuration of the event triggering in the LTM to the UE by sending the measurement-related configuration information, so that the UE can perform the event-triggered beam measurement reporting or the conditional LTM according to the measurement-related configuration information after receiving the measurement-related configuration information.

[0107] The event-triggered beam measurement can be measurement of the LTM Xth event (such as LTM event 3) or measurement of the LTM Yth event (such as LTM event 4). In some embodiments, the UE performs measurement based on the LTM Xth event based on the measurement-related configuration information, and in this case, the measurement result of the beam is judged based on the trigger condition defined based on the Xth event. In other embodiments, the UE performs measurement based on the LTM Yth event based on the measurement-related configuration information, and in this case, the measurement result of the beam is judged based on the trigger condition defined based on the Yth event.

[0108] In a case where the measurement result of the beam satisfies a trigger condition of the trigger event corresponding to the measurement-related configuration information, the terminal triggers reporting of the measurement result or performs the conditional LTM. Specifically, taking the trigger event as the above-mentioned event 4 and the measurement result of the beam as the measurement result of beam 1 as an example, the trigger condition of the trigger event is that when the measurement result of beam 1 >= the third threshold and the difference value >= the offset value offset1. At this time, the terminal triggers reporting of the measurement result or performs the conditional LTM; wherein the offset value offset1 is determined according to the measurement-related configuration information.

[0109] In the embodiments of the present application, the terminal receives the measurement-related configuration information sent by the network-side device and obtains the measurement configuration of the event triggering in the LTM, so that the UE can accurately and timely perform the event-triggered beam measurement reporting or the conditional LTM according to the measurement-related configuration information, avoiding the network-side device from being unable to obtain appropriate measurement results due to inaccurate or delayed measurement reporting, thereby affecting the subsequent handover process.

[0110] In a specific implementation, the network-side device further performs the following steps:

[0111] Step S420: The network-side device sends measurement resource configuration information to the terminal, and the measurement resource configuration information is used to determine a measurement beam, and the measurement resource configuration information includes at least one of the following:

[0112] F-1: a beam set, including one or more synchronization signal block (SSB) identities, or including one or more channel state information reference signal (CSI-RS) identities;

[0113] F-2: a cell set, including one or more cell identities;

[0114] F-3: a parameter related to a beam;

[0115] F-4: a parameter related to an event.

[0116] In the embodiments of the present application, the network side device sends the measurement resource configuration information to the UE, so that the UE determines the measurement beam according to the measurement resource configuration information, and the measurement resource configuration information includes at least one of the F-1 to F-4.

[0117] The beam set in the F-1 can be a beam list. The UE can determine the SSB or the CSI-RS (i.e. the measurement beam) for measurement according to the one or more SSB identities or the one or more CSI-RS identities in the beam set, and the measurement beam corresponding to the one or more SSB identities or the one or more CSI-RS identities in the beam set can be a beam in the current serving cell or a beam in one or more candidate cells.

[0118] The cell set in the F-2 can be a cell list. The multiple cell identities in the cell set include the identity of the current serving cell and the identity of one or more candidate cells. The UE can determine the corresponding candidate cell according to the one or more cell identities in the cell set, so as to take the beam corresponding to the candidate cell as the measurement beam.

[0119] The F-3 and the F-4 are related to the measurement beam. After the UE determines the measurement beam based on the measurement resource configuration information, the UE can perform the event-triggered beam measurement reporting or the conditional LTM based on the measurement beam according to the parameter related to the beam and / or the parameter related to the event. The specific manner of performing the event-triggered beam measurement reporting or the conditional LTM based on the measurement beam according to the parameter related to the beam and / or the parameter related to the event will be described below.

[0120] It can be understood that the beam-related parameters and the event-related parameters can be configured in various ways. In some embodiments, as shown in FIG. 5, the beam-related parameters are configured by measurement resource configuration information, the event-related parameters are configured by measurement-related configuration information, and the measurement-related configuration information (e.g., the event-related parameters) and the measurement resource configuration information (e.g., the beam-related parameters) are associated by a resource configuration identifier (resource config id) or a report configuration identifier (report id), so that the UE can perform event-triggered beam measurement reporting or conditional LTM based on the beam-related parameters and / or the event-related parameters.

[0121] In other embodiments, as shown in FIG. 6, the beam-related parameters and the event-related parameters are both configured by measurement resource configuration information, each trigger event corresponds to one beam in a beam set or one cell in a cell set (e.g., the nth trigger event corresponds to the nth beam in the beam set or the nth cell in the cell set), so that the UE can perform event-triggered beam measurement reporting or conditional LTM based on the beam-related parameters and / or the event-related parameters configured by the measurement resource configuration information.

[0122] In a specific implementation, the beam-related parameters include at least one parameter set from the following:

[0123] D-1: a set of offset values;

[0124] D-2: a set of hysteresis values;

[0125] D-3: a set of trigger times;

[0126] D-4: a set of leaving reporting parameters;

[0127] D-5: a set of reporting times;

[0128] D-6: a set of reporting intervals;

[0129] D-7: a set of event identifiers;

[0130] In each parameter set in the at least one parameter set, the nth parameter satisfies at least one of the following corresponding relationships: corresponding to the nth beam in the beam set; corresponding to the nth cell in the cell set; n is an integer greater than or equal to 1.

[0131] In the embodiments of the present application, the beam set refers to a set of beams configured by the network side device to the UE (for example, configured by the measurement resource configuration information), for the UE to perform measurement; the cell set refers to a set of cells configured by the network side to the UE, for the UE to perform measurement. The parameter set can be a parameter list (list), and the parameter set includes a plurality of parameter values. When configuring the parameters related to the beam, different parameters are configured as the corresponding parameter set, and each parameter is associated with the measurement beam and the cell. In some embodiments, each parameter in the parameter set corresponds to one beam in the beam set; for example, the first (n=1) offset value in the offset value set corresponds to the first beam in the beam set. In some embodiments, each parameter in the parameter set corresponds to one cell in the cell set; for example, the fourth (n=4) offset value in the offset value set corresponds to the fourth cell in the cell set. In some embodiments, each parameter in the parameter set corresponds to one beam in the beam set and one cell in the cell set; for example, the fifth (n=5) offset value in the offset value set corresponds to the fifth beam in the beam set and the fifth cell in the cell set.

[0132] Specifically, each offset in the D-1 item offset value set is used to determine whether the measurement result of the beam satisfies the triggering condition of the triggering event. When the difference between the measurement result of the beam and the threshold is greater than or equal to the offset value, it can be determined that the measurement result of the beam satisfies the triggering condition of the triggering event. For example, for event 4 described above, the offset value is the second offset value in event 4. When the measurement result of the beam is greater than or equal to the third threshold, and the difference between the measurement result of the beam and the third threshold is greater than or equal to the second offset value, it is determined that the measurement result of the beam satisfies the triggering condition of the triggering event. Through each offset in the offset value set, the offset value of each beam in the beam set is configured, or the offset value of each cell in the cell set is configured.

[0133] The hysteresis in the D-2 item hysteresis value set is used to determine whether the measurement result of the beam satisfies the threshold value. When the measurement result of the beam satisfies the sum of the threshold and the hysteresis value, it can be determined that the measurement result of the beam satisfies the threshold value. Through each hysteresis value in the hysteresis value set, the hysteresis value of each beam in the beam set is configured, or the hysteresis value of each cell in the cell set is configured.

[0134] The time to trigger (TTT) in the D-3 item trigger time set refers to the duration for which the trigger condition of the trigger event is met, and the measurement result of the beam is determined to meet the trigger condition of the trigger event only when the duration for which the trigger condition of the trigger event is met is greater than the trigger time. Through each trigger time in the trigger time set, the trigger time of each beam in the beam set is configured, or the trigger time of each cell in the cell set is configured.

[0135] The report On Leave in the D-4 item leave report parameter set refers to whether the UE needs to report when the measurement result no longer meets the event. Through each report On Leave in the leave report parameter set, the report On Leave of each beam in the beam set is configured, or the report On Leave of each cell in the cell set is configured.

[0136] The report Amount in the D-5 item report number set refers to the number of reports that the UE needs to perform each time the measurement result is reported. When the report number of the UE does not meet the report number, the UE performs the report, and when the report number meets the report number, the report is stopped. Through each report number in the report number set, the report number of each beam in the beam set is configured, or the report number of each cell in the cell set is configured.

[0137] The report Interval in the D-6 item report interval set refers to the time interval between two times of measurement result reporting performed by the UE. Through each report interval in the report interval set, the report interval of each beam in the beam set is configured, or the report interval of each cell in the cell set is configured.

[0138] The event identifier in the D-7 item event identifier set is used to associate the trigger event with the beam or with the cell, and the associated event parameters (for example, the threshold value in the event) are configured for the event identifier. Each event identifier corresponds to a trigger event, for example, the event identifier can be the event identifier of the event 1, the event 2, the event 3, the event 4 and the event 5 described above. When the measurement result of the beam meets the trigger condition of the associated trigger event, the UE performs the measurement result reporting or executes the conditional LTM. Through each event identifier in the event identifier set, the trigger event of each beam in the beam set is configured, or the trigger event of each cell in the cell set is configured.

[0139] In the embodiments of the present application, the at least one parameter set in the D-1 to D-7 is used to configure the parameters related to the beam, so that when the UE performs the event-triggered beam measurement reporting or conditional LTM, the event-triggered beam measurement can be performed based on the parameters related to the beam, and whether the measurement result of the beam meets the trigger condition of the trigger event is determined according to the parameters related to the beam. In this way, the UE can correctly and timely perform the event-triggered beam measurement reporting or conditional LTM based on the parameters related to the beam, avoiding the situation that the network side device cannot obtain the appropriate measurement result due to inaccurate or delayed measurement reporting, and thus affecting the subsequent handover process.

[0140] In a specific embodiment, the parameters related to the event include at least one of the following:

[0141] E-1: event identifier;

[0142] E-2: offset value;

[0143] E-3: hysteresis value;

[0144] E-4: trigger time;

[0145] E-5: leaving reporting parameter;

[0146] E-6: reporting times;

[0147] E-7: reporting interval.

[0148] In the embodiments of the present application, the configuration of the event-triggered reporting of the LTM is configured under the report type IE at the same time as the periodic configuration, wherein the event-triggered reporting and the periodic reporting belong to different reporting types, and the network side device can include at least one of the two in the reporting type configuration carried in the reporting configuration sent to the terminal, so that the terminal performs the event-triggered reporting or the periodic reporting based on the corresponding configuration.

[0149] Specifically, at least one parameter in the E-1 to E-7 is configured for each trigger event, different trigger events correspond to different parameters related to the event, and when the UE performs the event-triggered beam measurement reporting or conditional LTM, whether the measurement result of the beam meets the trigger condition of the trigger event can be determined by using the parameters related to the event corresponding to the trigger event. For example, for event 3, whether the measurement result of the beam meets the trigger condition of the trigger event is determined according to the parameters related to the event corresponding to the event 3.

[0150] Further, the parameters related to the event further include at least one of the following:

[0151] a first parameter value, the UE uses the first parameter value to determine whether the measurement result of the beam satisfies a triggering condition of a triggering event, in a case that a first identity associated with the candidate cell is the same as a second identity associated with a current serving cell of the UE;

[0152] a second parameter value, the UE uses the second parameter value to determine whether the measurement result of the beam satisfies the triggering condition of the triggering event, in a case that the first identity associated with the candidate cell is different from the second identity associated with the current serving cell of the UE.

[0153] In the embodiments of the present application, a first parameter value for an intra-CU (Centralized Unit) scenario of the same base station is configured, and a second parameter value for an inter-CU scenario of different base stations is configured. The first parameter value includes at least one of an event identity, an offset value, a hysteresis value, a triggering time, a leaving reporting parameter, a reporting number, and a reporting interval. The second parameter value also includes at least one of the event identity, the offset value, the hysteresis value, the triggering time, the leaving reporting parameter, the reporting number, and the reporting interval.

[0154] When the UE performs event-triggered beam measurement reporting or conditional LTM, the UE determines whether the candidate cell and the current serving cell belong to the same CU (Centralized Unit) according to a first identity associated with the candidate cell and a second identity associated with the current serving cell, that is, the cell switching is performed in the intra-CU scenario in the same CU, and the cell switching is performed in the inter-CU scenario in different CUs. The first identity associated with the candidate cell and the second identity associated with the current serving cell can be a security group identity or a CU identity, which represents whether the two cells need to update the key when switching with each other, and can be used to determine whether the two cells are in the same CU.

[0155] When the first identity associated with the candidate cell is the same as the second identity associated with the current serving cell of the UE, it indicates that the candidate cell and the current serving cell belong to the same CU, and the UE uses the first parameter value to determine whether the measurement result of the beam satisfies the triggering condition of the triggering event. When the first identity associated with the candidate cell is different from the second identity associated with the current serving cell of the UE, it indicates that the candidate cell and the current serving cell belong to different CUs, and the UE uses the second parameter value to determine whether the measurement result of the beam satisfies the triggering condition of the triggering event.

[0156] Correspondingly, in a case that the event-related parameter further includes at least one of the first parameter value and the second parameter value, the network-side device sends the measurement resource configuration information, and the UE further performs the following steps G1 to G4:

[0157] Step G1: The terminal receives the measurement resource configuration information sent by the network side device, and the measurement resource configuration information includes at least one of the following: a beam set including one or more SSB identifiers, or including one or more CSI-RS identifiers; a cell set including one or more cell identifiers;

[0158] Step G2: According to the measurement resource configuration information, the measurement beam is determined.

[0159] Step G3: In the case where the first identifier associated with the candidate cell where the measurement beam is located is the same as the second identifier associated with the current serving cell of the terminal, the terminal uses the first parameter value to determine whether the measurement result of the beam meets the triggering condition of the triggering event.

[0160] Step G4: In the case where the first identifier associated with the candidate cell where the measurement beam is located is different from the second identifier associated with the current serving cell of the terminal, the terminal uses the second parameter value to determine whether the measurement result of the beam meets the triggering condition of the triggering event.

[0161] In the embodiments of the present application, the UE determines the measurement beam according to the measurement resource configuration information sent by the network side device, and determines whether the candidate cell and the current serving cell belong to the same CU according to the first identifier associated with the candidate cell and the second identifier associated with the current serving cell. When the first identifier associated with the candidate cell is the same as the second identifier associated with the current serving cell of the UE, it indicates that the candidate cell and the current serving cell belong to the same CU, and at this time the UE uses the first parameter value to determine whether the measurement result of the beam meets the triggering condition of the triggering event. When the first identifier associated with the candidate cell is different from the second identifier associated with the current serving cell of the UE, it indicates that the candidate cell and the current serving cell belong to different CUs, and at this time the UE uses the second parameter value to determine whether the measurement result of the beam meets the triggering condition of the triggering event. In this way, the UE correctly and timely performs event-triggered beam measurement reporting or conditional LTM based on different measurement configuration parameters in different scenarios (i.e. intra-CU scenario and inter-CU scenario), avoiding the network side device from failing to obtain appropriate measurement results due to inaccurate or delayed measurement reporting, thereby affecting the subsequent handover process.

[0162] In a specific embodiment, the network side device further performs the following steps:

[0163] Step S430: The network-side device sends first indication information to the terminal, where the first indication information is used to indicate that, in the case where the measurement-related configuration information comprises the beam-related parameter and the event-related parameter, a target parameter is used to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event, and the target parameter is the beam-related parameter and / or the event-related parameter.

[0164] In the embodiments of the present application, the use of the target parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event specifically comprises: using the beam-related parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event; using the event-related parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event; using the beam-related parameter and the event-related parameter together to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event.

[0165] In the embodiments of the present application, the use of the target parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event specifically comprises: using the beam-related parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event; using the event-related parameter to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event; using the beam-related parameter and the event-related parameter together to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event.

[0166] In some embodiments, the beam-related parameter and the event-related parameter are added to obtain a comprehensive parameter, so that the measurement result of the beam is determined whether it satisfies the trigger condition of the trigger event according to the comprehensive parameter obtained by the addition. For example, for the offset value, the offset value 1 in the beam-related parameter and the offset value 2 in the event-related parameter are added, and the measurement result of the beam is determined whether it satisfies the trigger condition of the trigger event according to the offset value 3 obtained by the addition. For example, FIG. 5 is a schematic diagram of measurement-related configuration information in the embodiments of the present application, taking A3 event as an example, and the beam-related parameter and the event-related parameter are configured at the same time, that is, the offset value set offset list and the offset value A3-offset of the A3 event, and then the offset+A3-offset corresponding to the offset value set offset list is used as the final offset value offset value for determining whether the measurement result of the beam satisfies the trigger condition of the trigger event.

[0167] Correspondingly, the terminal also performs the following steps:

[0168] Step H1: In the case where the measurement-related configuration information comprises the beam-related parameter and the event-related parameter, a target parameter is used to determine whether the measurement result of the beam satisfies the trigger condition of the trigger event, and the target parameter is determined according to one of the following:

[0169] J-1 item: the first indication information sent by the network-side device;

[0170] Item J-2: priority information, used to indicate the priority of the beam-related parameter and the priority of the event-related parameter;

[0171] Item J-3: protocol agreement.

[0172] In the embodiments of the present application, the UE determines the target parameter (i.e., Item J-1) according to the first indication information sent by the network side device, at this time, the target parameter can be the beam-related parameter, or the event-related parameter, or the beam-related parameter and the event-related parameter (i.e., the beam-related parameter and the event-related parameter are used together). The UE determines the target parameter (i.e., Item J-2) according to the priority information, at this time, the target parameter is the one with higher priority between the beam-related parameter and the event-related parameter. The UE determines the target parameter (i.e., Item J-2) according to the protocol agreement, at this time, the target parameter can be the beam-related parameter, or the event-related parameter, or the beam-related parameter and the event-related parameter (i.e., the beam-related parameter and the event-related parameter are used together).

[0173] In a specific implementation, the network side device further performs the following steps:

[0174] Step S440: the network side device sends second indication information to the terminal, the second indication information is used to indicate that the measurement result of one beam is used to determine whether the trigger condition of the trigger event is met, or the second indication information is used to indicate that the measurement result of multiple beams is used by the UE to determine whether the trigger condition of the trigger event is met.

[0175] In the embodiments of the present application, according to the way in which the network side device instructs the UE to determine whether the trigger condition of the trigger event is met through the second indication information, the second indication information can be a number K, if K = 1, it indicates that the UE uses the measurement result of one beam to determine whether the trigger condition of the trigger event is met, if K is a number greater than 1, it indicates that the UE uses the measurement result of multiple beams to determine whether the trigger condition of the trigger event is met.

[0176] The second indication information can also directly indicate that the UE uses the measurement result of one beam to determine whether the trigger condition of the trigger event is met, or directly indicate that the UE uses the measurement result of multiple beams to determine whether the trigger condition of the trigger event is met, the second indication information can also instruct the UE to perform beam level measurement triggering or cell level measurement triggering, so as to determine whether the trigger condition of the trigger event is met according to the measurement result of one corresponding beam or the measurement result of multiple beams.

[0177] Correspondingly, the terminal performs the following steps:

[0178] Step K1: The terminal receives second indication information sent by the network side device.

[0179] Step K2: According to the second indication information, whether the trigger condition of the trigger event is satisfied is determined using the measurement result of one beam, or according to the second indication information, whether the trigger condition of the trigger event is satisfied is determined using the measurement result of multiple beams.

[0180] In the embodiments of the present application, the UE receives the second indication information and performs the determination of whether the trigger condition of the trigger event is satisfied based on the second indication information. In this way, the UE can accurately and timely perform the event-triggered beam measurement reporting or execute the conditional LTM based on the second indication information, avoiding the situation that the network side device cannot obtain suitable measurement results due to inaccurate or delayed measurement reporting, thereby affecting the subsequent handover process.

[0181] In a specific implementation, the network side device further performs the following steps:

[0182] Step S450: Send third indication information, which is used to indicate whether to use the measurement result of the best beam to determine whether the trigger condition of the trigger event is satisfied.

[0183] In the embodiments of the present application, the measurement result of the beam can be the RSRP measurement result, the RSRQ measurement result and the SINR measurement result, and the measurement result of the best beam is the RSRP measurement result corresponding to the best one or more beams, or the RSRQ measurement result corresponding to the best one or more beams, or the SINR measurement result corresponding to the best one or more beams.

[0184] Specifically, the third indication information can be a number K, indicating that the measurement result of the best K beams is used to determine whether the trigger condition of the trigger event is satisfied. In some embodiments, using the measurement result of the best K beams to determine whether the trigger condition of the trigger event is satisfied includes: taking a linear average of the measurement results of the K beams to obtain a final measurement result, and determining whether the trigger condition of the trigger event is satisfied according to the final measurement result. In other embodiments, if the measurement resource configuration information associated with the trigger event only configures L measurement beams for a certain cell (i.e., measurement based on cell level), L <= K, then the measurement results of the L measurement beams are taken to obtain a final measurement result, and whether the trigger condition of the trigger event is satisfied is determined according to the final measurement result.

[0185] Correspondingly, the terminal performs the following steps:

[0186] Step L1: The terminal receives the third indication information sent by the network side device.

[0187] Step L2: According to the third indication information, it is determined whether to use the measurement result of the best beam to determine whether the trigger condition of the trigger event is met, and the best beam includes at least one of the following: one beam with the best reference signal received power (RSRP) measurement result, or N beams with the best RSRP measurement result; one beam with the best reference signal received quality (RSRQ) measurement result, or N beams with the best RSRQ measurement result; one beam with the best signal to interference plus noise ratio (SINR) measurement result, or N beams with the best SINR measurement result, N is an integer greater than 1.

[0188] In the embodiments of the present application, the UE determines whether the trigger condition of the trigger event is met according to the measurement result of the beam indicated by the third indication information. When the third indication information indicates that the measurement result of the best beam is used to determine whether the trigger condition of the trigger event is met, the measurement result of the best beam is used to determine whether the trigger condition of the trigger event is met; when the third indication information does not indicate that the measurement result of the best beam is used to determine whether the trigger condition of the trigger event is met, the measurement result of any beam or any beam exceeding the threshold is used to determine whether the trigger condition of the trigger event is met. Wherein, any beam can be any beam in the candidate cell, or any beam in the beam set.

[0189] In this way, the UE can accurately and timely perform event-triggered beam measurement reporting or conditional LTM based on the third indication information, avoiding the network side device from failing to obtain suitable measurement results due to inaccurate or delayed measurement reporting, thereby affecting the subsequent handover process.

[0190] It can be understood that, in a case where the network side device sends the second indication information and the third indication information, the UE can determine the target beams according to the second indication information and the third indication information, and determine whether the trigger condition of the trigger event is met according to the measurement results of the target beams. For example, the second indication information indicates to use the measurement results of multiple beams to determine whether the trigger condition of the trigger event is met, and the third indication information indicates to use the measurement result of the best beam to determine whether the trigger condition of the trigger event is met; at this time, the multiple beams with the best measurement results are determined as the target beams (for example, the first N beams with the best measurement results are determined as the target beams). For another example, the second indication information indicates to use the measurement results of multiple beams to determine whether the trigger condition of the trigger event is met, and the third indication information does not indicate to use the measurement result of the best beam to determine whether the trigger condition of the trigger event is met; at this time, any multiple beams are determined as the target beams (for example, any K beams are determined as the target beams).

[0191] In a specific embodiment, in a case where the measurement result of the beam meets the trigger condition of the trigger event corresponding to the measurement related configuration information, the terminal triggers the reporting of the measurement result, including at least one of the following:

[0192] M-1 item: when the measurement result of the first beam meets the trigger condition of the trigger event, the measurement result of the first beam is put into a reporting set, and reporting is triggered;

[0193] M-2 item: when the measurement result of the second beam meets the trigger condition of the trigger event, multiple beams whose measurement results meet the trigger condition are put into the reporting set, and reporting is triggered;

[0194] M-3 item: when the measurement result of one or more beams in the reporting set does not meet the trigger condition of the trigger event, the one or more beams whose measurement results do not meet the trigger condition of the trigger event are removed from the reporting set; or, when one or more beams in the reporting set meet the leaving condition, the one or more beams meeting the leaving condition are removed from the reporting set.

[0195] In the embodiments of the present application, the UE measures the measurement beams, when the measurement result of the first beam meets the triggering condition of the triggering event, the measurement result of the first beam is put into the reporting set, and the reporting is triggered (i.e., M-1 item); the UE continues to measure the measurement beams, when the measurement result of the second beam meets the triggering condition of the triggering event, the measurement result of the second beam is put into the reporting set, and if the measurement result of the first beam still meets the triggering condition of the triggering event, the measurement result of the first beam is still in the reporting set, at this time, the measurement results of multiple beams in the reporting set are reported (i.e., M-2 item). If the measurement result of one or more beams (such as the first beam or the second beam) in the reporting set does not meet the triggering condition of the triggering event within a certain time, or when one or more beams in the reporting set meet the leaving condition, the M-3 item is executed. In this way, the UE realizes the reporting of the measurement result based on the event triggering according to the real-time measurement result of the beam.

[0196] In a specific embodiment, in the case that the measurement result of the beam meets the triggering condition of the triggering event corresponding to the measurement related configuration information, the terminal triggers the reporting of the measurement result, including at least one of the following:

[0197] When the measurement result of the fourth beam meets the triggering condition of the triggering event, and the total number of beams in the reporting set is greater than the threshold M corresponding to the reporting signaling, the UE performs one of the following behaviors:

[0198] N-1 item: skip the reporting behavior once;

[0199] N-2 item: report the latest measurement results of each beam in the reporting set when the measurement result of any beam in the reporting set changes, or when the beam with the best measurement result in the reporting set changes;

[0200] N-3 item: the UE reports the measurement results of the fourth beam and M-1 beams selected from the reporting set according to a target selection manner, and the target selection manner is: selecting M-1 beams with the best measurement results, selecting M-4 measurement results triggered first, or selecting M-1 measurement results triggered first;

[0201] N-4 item: select M beams with the best measurement results from the fourth beam and the reporting set, and report;

[0202] Among them, the beams in the reporting set are beams with measurement results meeting the triggering condition of the triggering event.

[0203] In the embodiments of the present application, in the process of triggering the reporting of the measurement result, when the total number of beams in the reporting set is greater than the threshold M corresponding to the reporting signaling, no beam can be placed in the reporting set any more. At this time, the measurement result of the fourth beam meets the triggering condition of the triggering event, and the UE performs any one of the behaviors in the N-1th to N-4th items.

[0204] Specifically, the UE can select to perform the N-1th item of skipping the reporting behavior once, at this time, the measurement result of the fourth beam is not reported.

[0205] The UE can select to perform the N-2th item, and report the latest measurement result of each beam in the reporting set when the measurement result of any beam in the reporting set changes, or when the beam with the best measurement result in the reporting set changes. For example, the reporting set includes beam 1, beam 2 and beam 3, the measurement result of any beam in the reporting set changes to the latest measurement result of any one of beam 1, beam 2 and beam 3, at this time, the latest measurement result of beam 1, beam 2 and beam 3 is reported; when the beam 1 with the best measurement result changes to the beam 3 with the best measurement result, the latest measurement result of beam 1, beam 2 and beam 3 is also reported.

[0206] The UE selects to perform the N-3th item, reports the measurement result of the fourth beam, and selects the measurement result of M-1 beams from the current reporting set for reporting. For example, for beam 1, beam 2 and beam 3 in the reporting set, the UE can select the two beams with the best measurement results, or select the beams 1 and 2 triggered first, or select the beams 2 and 3 triggered last, and finally report beam 1, beam 2 and beam 8, or report beam 2, beam 3 and beam 8.

[0207] The UE selects to perform the N-4th item, and selects the M beams with the best measurement results from the fourth beam and the reporting set for reporting. For example, the three beams with the best measurement results, such as beam 1, beam 3 and beam 8, are selected for reporting.

[0208] In the embodiments of the present application, a method for a terminal to trigger the reporting of a measurement result is proposed when the total number of beams in the reporting set is greater than the threshold M corresponding to the reporting signaling. Thus, the UE can accurately and timely perform the event-triggered beam measurement reporting or conditional LTM, avoiding the network side device from failing to obtain suitable measurement results due to inaccurate or delayed measurement reporting, and thus affecting the subsequent handover process.

[0209] The configuration information sending method proposed in the above embodiment is described through the following embodiment.

[0210] Embodiment One

[0211] Embodiment One describes the process of the terminal performing event-triggered beam measurement reporting or conditional LTM in the case of taking the above-mentioned event 4 as an example and taking the beam-related parameter as the offset value set Offset list. The specific steps are as follows:

[0212] Step 1: The network side device sends measurement resource configuration information, which is used to determine the measurement beam, and the measurement resource configuration information includes at least one of the following: a beam set including one or more SSB identifiers or one or more CSI-RS identifiers; a cell set including one or more cell identifiers; and an offset value set Offset list.

[0213] The measurement resource configuration information is associated with the first reporting configuration, and the first reporting configuration corresponds to event 4.

[0214] Step 2: The UE receives the measurement resource configuration information, determines the measurement beam according to the measurement resource configuration information, and performs event-triggered beam measurement on the measurement beam to obtain the measurement result of the beam.

[0215] Embodiment Two

[0216] Embodiment Two describes the process of the terminal performing event-triggered beam measurement reporting or conditional LTM in the case of the network side device configuring the measurement resource configuration information and the measurement-related configuration information, and the parameter value of the event-related parameter in the configuration of the measurement-related configuration information including the first parameter value and the second parameter value, taking the above-mentioned event 4 as an example. The specific steps are as follows:

[0217] Step 1: The network side device sends measurement resource configuration information, which is used to determine the measurement beam, and the measurement resource configuration information includes at least one of the following: a beam set including one or more SSB identifiers or one or more CSI-RS identifiers; and a cell set including one or more cell identifiers.

[0218] Step 2: The network-side device sends measurement-related configuration information, which includes parameters related to the event, i.e., a first parameter value and a second parameter value. The first parameter value includes a time-to-trigger (TTT) for intra-CU, and the second parameter value includes a time-to-trigger (TTT) for inter-CU.

[0219] Steps 1 to 2 can be executed simultaneously or in a certain order, and the execution order of steps 1 to 2 in the embodiments of the present application is not limited.

[0220] Step 3: The UE receives the measurement resource configuration information and determines the measurement beams according to the measurement resource configuration information, and performs event-triggered beam measurement on the measurement beams to obtain the measurement results of the beams.

[0221] Step 4: In the case where the first identifier associated with the candidate cell where the measurement beam is located is the same as the second identifier associated with the current serving cell of the UE, the UE uses the first parameter value (time-to-trigger (TTT) for intra-CU) to determine whether the measurement results of the beams meet the triggering condition of the triggering event; in the case where the first identifier associated with the candidate cell where the measurement beam is located is different from the second identifier associated with the current serving cell of the UE, the UE uses the second parameter value (time-to-trigger (TTT) for inter-CU) to trigger the reporting or execution condition LTM of the measurement results, and determines whether the measurement results of the beams meet the triggering condition of the triggering event.

[0222] The determination of whether the measurement results of the beams meet the triggering condition of the triggering event includes: the measurement results of the beams >= a third threshold, the difference >= a second offset value, and the triggering time TTT is exceeded, then it is considered that the triggering condition is met.

[0224] Embodiment Three

[0225] Embodiment Three describes the process of the network-side device configuring measurement resource configuration information, measurement-related configuration information, second indication information, and sending third indication information, and the UE performing event-triggered beam measurement reporting or condition LTM based on the above configurations. The specific steps are as follows:

[0226] Step 1: The network-side device sends measurement resource configuration information, which is used to determine the measurement beams, and includes at least one of the following: a beam set including one or more SSB identifiers, or including one or more CSI-RS identifiers; a cell set including one or more cell identifiers.

[0227] Step 2: The network-side device sends measurement-related configuration information, the measurement-related configuration information including event-related parameters, the event-related parameters including at least one of the following: event identification; offset value; hysteresis value; triggering time; leaving reporting parameter; reporting times; reporting interval.

[0228] Step 3: The network-side device sends second indication information and third indication information.

[0229] Wherein, steps 1 to 3 can be executed simultaneously, or in a certain order, and the execution order of steps 1 to 3 in the embodiments of the present application is not limited.

[0230] Step 4: The UE determines the measurement beam according to the measurement resource configuration information, and performs event-triggered beam measurement on the measurement beam based on the measurement-related configuration information to obtain the measurement result of the beam.

[0231] Step 5: According to the second indication information, it is judged whether the trigger condition of the trigger event is met. That is, according to the second indication information, the measurement result of one beam is used to judge whether the trigger condition of the trigger event is met, or according to the second indication information, the measurement results of multiple beams are used to judge whether the trigger condition of the trigger event is met.

[0232] Step 6: According to the third indication information, it is determined whether the measurement result of the best measurement beam is used to judge whether the trigger condition of the trigger event is met. That is, when the third indication information indicates that the measurement result of the best measurement beam is used to judge whether the trigger condition of the trigger event is met, the measurement result of the best measurement beam is used to judge whether the trigger condition of the trigger event is met; when the third indication information does not indicate that the measurement result of the best measurement beam is used to judge whether the trigger condition of the trigger event is met, the measurement result of any beam is used to judge whether the trigger condition of the trigger event is met.

[0233] Wherein, steps 5 and 6 are executed according to the indication of the network-side device.

[0234] Step 7: In the case where the measurement result of the beam meets the trigger condition of the corresponding trigger event, the terminal triggers the reporting of the measurement result or executes the conditional LTM.

[0235] Embodiment Four

[0236] Embodiment Four describes the process of the UE terminal triggering the reporting of the measurement result in the case where the measurement result meets the trigger condition of the corresponding trigger event. The specific steps are as follows:

[0237] Step 1: The network side device sends measurement resource configuration information, the measurement resource configuration information is used to determine measurement beams, and the measurement resource configuration information includes at least one of the following: a beam set including one or more SSB identifiers, or including one or more CSI-RS identifiers; a cell set including one or more cell identifiers.

[0238] Step 2: The network side device sends measurement related configuration information, the measurement related configuration information includes parameters related to an event, and the parameters related to the event include at least one of the following: an event identifier; an offset value; a hysteresis value; a triggering time; a leaving reporting parameter; a reporting number; and a reporting interval.

[0239] Step 3: The UE determines measurement beams according to the measurement resource configuration information, and performs event triggered beam measurement on the measurement beams based on the measurement related configuration information to obtain measurement results of the beams.

[0240] Step 4: When the measurement results of the beams satisfy the triggering condition of the triggering event corresponding to the measurement related configuration information, and when the measurement result of a first beam satisfies the triggering condition of the triggering event, the measurement result of the first beam is put into a reporting set, and reporting is triggered.

[0241] For example, the UE measures the measurement beams, and when the measurement result of beam 1 satisfies the triggering condition of the triggering event, the UE puts the measurement result of beam 1 into the reporting list (reporting set) and triggers reporting.

[0242] Step 5: Continue to perform event triggered beam measurement on the measurement beams, and when the measurement result of a second beam satisfies the triggering condition of the triggering event, put the multiple beams whose measurement results satisfy the triggering condition into the reporting set, and trigger reporting.

[0243] For example, the UE continues to measure the measurement beams, and when the measurement result of beam 2 satisfies the triggering condition of the triggering event, the UE puts the measurement result of beam 2 into the reporting set, and since the measurement result of beam 1 still satisfies the triggering condition of the triggering event, beam 1 is still in the reporting set, and reporting is triggered, at this time, the measurement results of beams 1 and 2 are reported.

[0244] Step 6: When the measurement result of one or more beams in the reporting set does not satisfy the triggering condition of the triggering event, remove the one or more beams whose measurement results do not satisfy the triggering condition of the triggering event from the reporting set; or when one or more beams in the reporting set satisfy a leaving condition, remove the one or more beams that satisfy the leaving condition from the reporting set.

[0245] For example, at a certain time, the measurement result of beam 1 or beam 2 no longer meets the triggering condition of the triggering event, or one or more beams in the reporting set meet the leaving condition, the UE removes them from the reporting set.

[0246] Step 7: When the measurement result of the fourth beam meets the triggering condition of the triggering event, and the total number of beams in the reporting set is greater than the threshold M corresponding to the reporting signaling, the UE performs one of the following behaviors: skips this time of reporting; reports the latest measurement results of each beam in the reporting set when the measurement result of any beam in the reporting set changes, or when the best beam in the reporting set changes; the UE reports the measurement results of the fourth beam and M-1 beams selected from the reporting set according to a target selection manner, the target selection manner being: selecting M-1 beams with the best measurement results, selecting M-1 beams that trigger first, or selecting M-1 beams that trigger first; selecting M beams with the best measurement results from the fourth beam and the reporting set, and reporting; wherein the beams in the reporting set are beams whose measurement results meet the triggering condition of the triggering event.

[0247] For example, assume that at a certain time, the measurement result of beam 8 meets the triggering condition of the triggering event, but there are beam 1, beam 2 and beam 3 in the reporting set, and the reporting signaling size can only accommodate 3, at this time the UE skips this time of reporting, that is, does not report the measurement result of beam 8. If the latest measurement result of any one of beam 1, beam 2 and beam 3 is different or the highest beam changes, the UE reports the new measurement results of beam 1, beam 2 and beam 3. When the measurement result of beam 8 needs to be reported, the UE can additionally select two beams with the best measurement results, or select beam 1 and beam 2 that trigger first, or select beam 2 and beam 3 that trigger later, and finally report beam 1, beam 2 and beam 8, or report beam 2, beam 3 and beam 8. The UE can also select three beams with the best measurement results for reporting, for example, beam 1, beam 3 and beam 8.
