[0059] 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.

[0060] LTM measurement configuration and reporting configuration:

[0061] 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.

[0062] In addition, one or more LTM related CSI reporting configurations are included in the serving cell configuration of the UE, each CSI reporting configuration including the following information:

[0063] LTM CSI reporting configuration identifier;

[0064] LTM CSI resource configuration identifier;

[0065] LTM reporting configuration type, including periodic reporting / semi-persistent reporting based on a physical uplink control channel (PUCCH) and corresponding reporting resources;

[0066] LTM reporting content, including the number of candidate cells for LTM CSI reporting and the number of RSs reported for each cell.

[0067] 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.

[0068] L3 measurement configuration and reporting configuration:

[0069] The network configures the UE in RRC connected state (RRC_CONNECTED) to perform L3 (layer 3) measurement, and 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:

[0070] 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.

[0071] Reporting configuration, each reporting configuration including: reporting criteria, the reporting criteria for triggering the UE to send measurement reporting, which can be periodic reporting or event-triggered reporting; RS type, the RS type for indicating which RS the UE uses to derive L3 measurement results; reporting format, i.e., the parameters (such as RSRP, reference signal received power RSRP) included in the measurement reporting; in addition, the reporting configuration can also include other related information (such as the maximum number of cells reported by the UE and the maximum number of beams reported for each cell).

[0072] 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.

[0073] Quantity configuration, which defines the filtering configuration parameters for all event evaluation and related reporting, as well as periodic measurement reporting.

[0074] Measurement gap, the period for UE to perform measurement.

[0075] 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 channel state information reference signal CSI-RS according to the reference signal type (RS-type) in the reporting configuration associated with the MO, and decides to perform measurement of reference signal receiving power (Reference Signal Receiving Power, RSRP), reference signal receiving quality (Reference Signal Received Quality, RSRQ) or signal to interference plus noise ratio (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.

[0076] In summary, L3 measurement configuration can support event triggered measurement reporting, that is, measurement reporting will only be performed when the pre-defined measurement event is met. In this way, unnecessary reporting can be reduced. 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 accurately trigger the event and how to accurately reflect the measurement result of the cell through beam level measurement, the related technology does not give a solution.

[0077] Therefore, the embodiments of the present application provide a measurement method, a configuration information sending method, a terminal and a network side device. The measurement method comprises: performing at least one first operation by a terminal when at least one first target beam changes, the first target beam being a beam used for judging whether a measurement result meets a triggering condition; judging, by the terminal, whether the measurement result of the first target beam after the change meets the triggering condition based on a parameter value after the at least one first operation is performed; and the at least one first operation comprises: continuing to calculate a time when the triggering condition is met; continuing to calculate a number of times when the triggering condition is met; continuing to evaluate a triggering time; and determining whether to reset an offset value based on indication information sent by a network side device. In this way, an event-triggered measurement reporting mechanism for LTM is introduced through the at least one first operation. The terminal can accurately and timely perform measurement reporting or conditional LTM (i.e., conditional LTM) or perform conditional reconfiguration in the case where the first target beam changes, thereby avoiding that the network side cannot obtain a suitable measurement result due to inaccurate or delayed measurement reporting, and thus affecting a subsequent handover process.

[0078] The measurement method, the configuration information sending method, the terminal and the network side device provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios.

[0079] In order to facilitate understanding of the present application, triggering events for triggering beam measurement reporting or conditional LTM of a UE are exemplified.

[0080] Event one: when a measurement result of a first beam of a serving cell is greater than or equal to a first threshold;

[0081] Event two: when the measurement result of the first beam of the serving cell is less than or equal to a second threshold;

[0082] Event three: when a measurement result of a second beam of a candidate cell is greater than or equal to the measurement result of the first beam of the serving cell, and a difference value is greater than or equal to a first offset value;

[0083] Event four: when the measurement result of the second beam of the candidate cell is greater than or equal to a third threshold, and the difference value is greater than or equal to a second offset value;

[0084] Event five: when the measurement result of the first beam of the serving cell is less than or equal to a fourth threshold and the measurement result of the second beam of the candidate cell is greater than or equal to a fifth threshold.

[0085] The second beam (referring to the beam involved in the above event one to event five) is a beam with the best measurement result in one or more candidate cells, and specifically can be at least one of the following:

[0086] A-1: one beam with the best RSRP measurement result, or N beams with the best RSRP measurement result;

[0087] A-2: one beam with the best RSRQ measurement result, or N beams with the best RSRQ measurement result;

[0088] A-3: one beam with the best SINR measurement result, or N beams with the best SINR measurement result;

[0089] In the embodiments of the present application, the best beam in terms of measurement result refers to the best beam in terms of quality among all beams of one or more candidate cells to which the terminal is configured 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 parameter), 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.

[0090] In some embodiments, the second beam (referring to the beam involved in the above events 1 to 5) can also be at least one of the following in one or more candidate cells:

[0091] A-4: the second beam is the best beam exceeding a preset threshold value;

[0092] A-5: the second beam is the best N beams exceeding a preset threshold value;

[0093] A-6: the second beam is any beam exceeding a preset threshold value;

[0094] A-7: the second beam is any N beams exceeding a preset threshold value;

[0095] A-8: the second beam is any one or N beams in the measurement resource configuration information;

[0096] A-9: the second beam is any one or N beams exceeding the threshold in the measurement resource configuration information.

[0097] The first beam (referring to the beam involved in the above events 1 to 5) can be at least one of the following in the serving cell:

[0098] 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;

[0099] B-2: one or more beams associated with the indicated TCI state;

[0100] B-3: one or more beams for which the TCI state is activated;

[0101] B-4: a beam currently used by the terminal.

[0102] In the embodiments of the present application, the UE can determine whether the trigger condition of the trigger event (for example, event four) is met by the measurement result of the second beam determined by the A-1 to A-9 items above, or determine whether the trigger condition of the trigger event (for example, event one) is met by the measurement result of the first beam determined by the B-1 to B-4 items above, or determine whether the trigger condition of the trigger event (for example, event three) is met by the measurement result of the second beam determined by the A-1 to A-9 items above and the measurement result of the first beam determined by the B-1 to B-4 items above. Hereinafter, "satisfying the trigger condition" is equivalent to satisfying the trigger condition corresponding to any one of the trigger events (for example, events one to five).

[0103] In a first aspect of the embodiments of the present application, a measurement method is provided, which is applied to a terminal. Referring to FIG. 4, FIG. 4 shows a step flowchart of a measurement method. As shown in FIG. 4, the method comprises:

[0104] In step S401, the terminal performs at least one first operation when at least one first target beam changes, and the first target beam is a beam used to determine whether the measurement result satisfies the trigger condition;

[0105] In step S402, the terminal determines whether the measurement result of the first target beam after the change satisfies the trigger condition based on the parameter value after the at least one first operation is performed.

[0106] The at least one first operation comprises:

[0107] C-1: continue to calculate the time for satisfying the trigger condition; the continue to calculate means that the time for satisfying the trigger condition is continued to be calculated on the basis of the time for satisfying the trigger condition that has been calculated before the first target beam changes, that is, the time for satisfying the trigger condition is not reset.

[0108] C-2: continue to calculate the number of times for satisfying the trigger condition; the continue to calculate means that the number of times for satisfying the trigger condition is continued to be calculated on the basis of the number of times for satisfying the trigger condition that has been calculated before the first target beam changes, that is, the number of times for satisfying the trigger condition is not reset.

[0109] C-3: Continue to evaluate the triggering time; continue to evaluate the triggering time based on the triggering time that has been evaluated before the first target beam occurs, i.e., do not reset the triggering time.

[0110] C-4: Recalculate the time when the triggering condition is met;

[0111] C-5: Recalculate the number of times the triggering condition is met;

[0112] C-6: Re-evaluate the triggering time;

[0113] C-7: Determine whether to reset the offset value based on the indication information sent by the network side device.

[0114] In the embodiments of the present application, the terminal refers to a user equipment (User Equipment, UE), which can be the terminal device 11 in FIG. 1. For examples of the terminal device 11, please refer to the foregoing description, which will not be repeated here. The network side device can be the core network device or the access network device 12 in FIG. 1. For examples of the network side device 12, please refer to the foregoing description, which will not be repeated here.

[0115] In specific implementation, when the measurement result of the first target beam meets the triggering condition of the triggering event (any one of events one to five described above), the UE judges that the triggering event occurs. After the triggering event occurs, the UE does not directly trigger beam measurement reporting or conditional LTM. Instead, within a certain time T (after the triggering event occurs), the number K of times that the measurement result of the first target beam meets the triggering condition (i.e., the triggering condition corresponding to the triggering event) is greater than or equal to M, and then the UE triggers the beam measurement reporting or the conditional LTM, wherein the values of M and T can be set according to actual application circumstances.

[0116] Specifically, after the UE judges that the triggering event occurs, a first timer (used to calculate whether the triggering condition is met) is started, or a time window TX is defined and the duration is started to be calculated, and the value of a first counter (initial value is 0, used to calculate the number of times the triggering condition is met) is added by 1. In the case that the measurement result of the first target beam obtained by the next measurement still meets the triggering condition, the value of the first counter is added by 1. Optionally, in the case that the measurement result of the first target beam obtained by the next measurement still meets the triggering condition, and the duration is higher than the triggering time (TTT), the value of the first counter is added by 1. In the case that the number of times the triggering condition is met K calculated by the first counter is greater than or equal to M, and the time whether the triggering condition is met calculated by the first timer does not exceed T, the beam measurement reporting or the condition LTM is triggered. In this process, if at least one first target beam changes, the UE performs at least one first operation (step S401), and then judges whether the measurement result of the first target beam after the change meets the triggering condition based on the parameter value after the at least one first operation is performed (step S402). Exemplarily, for event three, the measurement result of the beam of the candidate cell and the measurement result of the beam of the serving cell need to be compared at the same time, and if one of the beams changes, it means that the first target beam changes, and the UE needs to perform at least one first operation.

[0117] Further, the network side device pre-sends the measurement related configuration information to the UE, and the measurement related configuration information includes at least one of the following parameters: beam related parameters; event related parameters. Specifically, the beam related parameters refer to the configuration parameters 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 beam related parameters; the event related parameters refer to the configuration parameters related to the triggering event, and different triggering events correspond to different event related parameters.

[0118] The network side device sends at least one measurement related configuration information to accurately configure the measurement configuration of the event triggered in the LTM to the UE, so that the UE can perform the event triggered beam measurement reporting or the condition LTM or the condition reconfiguration based on the at least one measurement related configuration information after receiving the at least one measurement related configuration information. Among them, the event triggered beam measurement reporting refers to that in the case that the measurement result of the beam meets the triggering condition, the UE reports the corresponding measurement result; the event triggered condition LTM refers to that in the case that the measurement result of the beam meets the triggering condition, the UE performs the condition LTM based on the measurement result.

[0119] For example, for the fourth event, the measurement result of the beam is the measurement result of the beam 1, and the measurement result of the beam 1 is greater than or equal to the third threshold and the difference value is greater than or equal to the offset value offset1, which means that the trigger condition is met. At this time, the terminal triggers the reporting of the measurement result or performs the condition LTM. The offset value offset1 is determined according to the measurement related configuration information.

[0120] In an optional embodiment, the first target beam changes, including at least one of the following:

[0121] The first target beam changes from a first beam to a second beam. In this embodiment, the first beam and the second beam refer to two beams with different beam identifiers or different beam numbers, and the meanings are different from the meanings of the beams (A-1 to A-9, B-1 to B-5) involved in the events one to five described above.

[0122] The measurement quantity of the first target beam changes, for example, the measurement quantity changes from RSRP to RSRQ.

[0123] The type configuration of the reference signal corresponding to the first target beam changes, for example, the type changes from SSB to CSI-RS.

[0124] The resource configuration of the reference signal corresponding to the first target beam changes. For example, when the first target beam is the best beam, the measurement result of the terminal is the best beam, and the first target beam is beam 1 in the resource configuration. However, the measurement result of the best beam changes to beam 2 in the resource configuration later.

[0125] In an optional embodiment, the first target beam includes at least one of the following:

[0126] Any one of the measurement resource configuration information;

[0127] The best beam in the measurement result;

[0128] The best beam in the measurement result includes at least one of the following:

[0129] The reference signal received power (RSRP) measurement result of the best beam, or the RSRP measurement result of the N best beams;

[0130] The reference signal received quality (RSRQ) measurement result of the best beam, or the RSRQ measurement result of the N best beams;

[0131] The signal to interference plus noise ratio (SINR) measurement result of the best beam, or the SINR measurement result of the N best beams, N being an integer greater than 1.

[0132] In one case, the first target beam can be any one of the beams indicated in the measurement resource configuration information sent by the network side device. The measurement resource refers to the time-frequency domain resource used for measurement. Specifically, the network side device sends the measurement resource configuration information to the UE, and the measurement resource configuration information includes a beam list and / or a cell list. In addition, the network side device can also send the measurement reporting configuration information to the UE, which is used to instruct the UE to perform measurement reporting according to the event-related parameters and / or beam-related parameters in the measurement reporting configuration information. For any one of the beams in the measurement resource configuration information, if the UE measures that the beam meets the triggering condition, it will be used as the first target beam to determine whether the measurement result meets the triggering condition, that is, in the case that the UE measures that the beam meets the condition corresponding to the triggering event (the number K of times that the measurement result of the beam meets the triggering condition within a certain time T after the triggering event occurs is greater than or equal to M), the beam reporting is triggered or the condition LTM is executed.

[0133] In another case, the first target beam can also be the beam with the best measurement result.

[0134] In one possible implementation, the beam with the best measurement result is any one of the following:

[0135] the beam with the best measurement result in the beams associated with the first candidate cell, the first candidate cell being one of the candidate cells in the cell set contained in the measurement resource configuration information;

[0136] the beam with the best measurement result in the beams associated with all candidate cells, the all candidate cells being all candidate cells in the cell set contained in the measurement resource configuration information.

[0137] Specifically, the network-side device sends measurement resource configuration information to the UE, and the measurement resource configuration information includes a beam set and / or a cell set (generally in the form of a list). The beam set (cell set) refers to a set of beams (a set of cells) configured by the network-side device to the terminal for measurement by the terminal. In addition, the network-side device can also send measurement reporting configuration information to the UE, which is used to instruct the UE to perform measurement reporting according to the event-related parameters and / or beam-related parameters in the measurement reporting configuration information. For the beams in the measurement resource configuration information, after the terminal completes the measurement of all the beams, the beam with the best measurement result is used as the first target beam to determine whether the beam meets the triggering condition, and if it meets the triggering condition, the beam reporting is triggered or the condition LTM is executed. Specifically, there are two ways to determine the beam with the best measurement result: one is that after the measurement of all the beams of a certain cell (i.e., a candidate cell in the cell set contained in the measurement resource configuration information) is completed, the beam with the best measurement result among all the beams associated with the cell is selected as the first target beam. The other is that after the measurement of all the beams across cells (i.e., all candidate cells in the cell set contained in the measurement resource configuration information) belonging to the same measurement resource configuration information is completed, the beam with the best measurement result is selected as the first target beam.

[0138] The following embodiments further describe the measurement method based on the above embodiments.

[0139] Embodiment one,

[0140] This embodiment describes the specific execution manner of the C-1 item, the C-2 item, the C-4 item, and the C-5 item in the first operation in the case where the first target beam changes, that is, the terminal needs to determine whether to recalculate (equivalent to whether to reset) the time of meeting the triggering condition and whether to recalculate (equivalent to whether to reset) the number of times of meeting the triggering condition when the first target beam changes. The specific content is as follows:

[0141] In an optional embodiment, the terminal performs at least one first operation when the first target beam changes, including:

[0142] When at least one first target beam changes, any of the following first operations is performed:

[0143] D-1: Recalculate the time of meeting the triggering condition and the number of times of meeting the triggering condition.

[0144] Specifically, after the UE judges that the triggering event occurs, the first timer (used to calculate whether the triggering condition is met) is started, and the value of the first counter (initial value is 0, used to calculate the number of times the triggering condition is met) is added by 1. In the case that the measurement result of the first target beam still meets the triggering condition and the duration is higher than the triggering time TTT next time, the value of the first counter is added by 1. In the case that the number of times the triggering condition is met K calculated by the first counter is greater than or equal to M, and the time whether the triggering condition is met calculated by the first timer does not exceed T, the triggering beam measurement reporting or condition LTM is judged. In this process, if the first target beam changes, the first timer is restarted to recalculate (equivalent to reset) the time whether the measurement result of the changed first target beam meets the triggering condition, and the first counter is reset to clear the number of times the triggering condition is met and recalculate (equivalent to reset) the number of times the measurement result of the changed first target beam meets the triggering condition.

[0145] D-2: Do not recalculate the time whether the triggering condition is met, and do not recalculate the number of times the triggering condition is met.

[0146] In the process of judging whether the triggering beam measurement reporting or condition LTM is triggered by the UE (i.e., the process of calculating by using the first timer and the first counter), if the first target beam changes, the counting progress of the first timer before the first target beam changes is retained, the time whether the measurement result of the changed first target beam meets the triggering condition is not recalculated (equivalent to continue calculating) (for example, before the first target beam changes, the first timer has counted 5 ms, then after the first target beam changes, the first timer continues to count from 5 ms), and the first counter is not reset, the number of times the triggering condition is met calculated before the first target beam changes is retained, and the number of times the measurement result of the changed first target beam meets the triggering condition is not recalculated (equivalent to continue calculating) (for example, before the first target beam changes, the first counter has counted 5 times, then after the first target beam changes, the first counter continues to count from 5 times).

[0147] D-3: Do not recalculate the time whether the triggering condition is met, and recalculate the number of times the triggering condition is met.

[0148] In the above-mentioned UE judging whether to trigger the beam measurement reporting or the conditional LTM procedure, if the first target beam changes, the counting progress of the first timer before the first target beam changes is preserved, the time whether the measurement result of the changed first target beam meets the triggering condition is not recalculated (equivalent to continue calculating), and the first counter is reset, the number of times of meeting the triggering condition is cleared, or a new second counter is separately enabled for the changed first target beam to recalculate the number of times of meeting the triggering condition.

[0149] D-4 item: Recalculate the time whether the triggering condition is met, and do not recalculate the number of times of meeting the triggering condition.

[0150] In the above-mentioned UE judging whether to trigger the beam measurement reporting or the conditional LTM procedure, if the first target beam changes, the first timer is restarted to recalculate the time whether the measurement result of the changed first target beam meets the triggering condition, and the first counter is not reset, the number of times of meeting the triggering condition calculated before the first target beam changes is preserved, and the number of times of meeting the triggering condition of the changed first target beam is not recalculated (equivalent to continue calculating).

[0151] In an optional embodiment, the counting start time of calculating the time whether the triggering condition is met is any one of the following:

[0152] The time point configured by the network side device;

[0153] The time point when the measurement result of the first target beam meets the triggering condition for the first time.

[0154] Specifically, the counting start time of starting the first timer (for calculating the time whether the triggering condition is met) has two kinds: one is directly according to the time point (fixed resource position) indicated in the measurement resource configuration information sent by the network side device. The other is at the time point when the measurement result of the first target beam meets the triggering condition for the first time, that is, at the time point when the UE judges that the triggering event occurs.

[0155] In an optional embodiment, the terminal performs at least one first operation when the first target beam changes, including:

[0156] When the first target beam changes and the measurement result of the first target beam after the change does not meet the triggering condition, any one of the following first operations is performed:

[0157] Stop calculating the time whether the triggering condition is met, and wait for the measurement result of the first target beam after the change to meet the triggering condition again to recalculate the time whether the triggering condition is met.

[0158] recomputing the time when the triggering condition is satisfied.

[0159] In the above-mentioned UE determining whether to trigger the beam measurement reporting or the conditional LTM procedure, if the first target beam changes and the measurement result of the first target beam after the change no longer satisfies the triggering condition of the triggering event, exemplary, the beam with the best measurement result is taken as the first target beam, and the beam A with the best measurement result is currently taken as the first target beam, which satisfies the triggering condition of the triggering event, the UE starts the first timer to calculate the time when the triggering condition is satisfied. During this process, the first target beam changes, the beam with the best measurement result changes from the beam A to the beam B, and the measurement result of the beam B no longer satisfies the triggering condition of the triggering event. In this case, two processing methods can be taken: one is to stop the first timer and suspend the calculation of whether the triggering condition is satisfied, and wait for the measurement result of the beam B (i.e. the changed first target beam) to satisfy the triggering condition of the triggering event again, and then restart the first timer. The other is to directly restart the first timer and recalculate the time when the triggering condition is satisfied.

[0160] Embodiment two,

[0161] This embodiment describes the specific execution mode of the C-3 item and the C-6 item in the first operation in the case where the first target beam changes, that is, the terminal needs to determine whether to reevaluate the triggering time when the first target beam changes. The specific content is as follows:

[0162] In an optional embodiment, the terminal performs at least one first operation when the first target beam changes, including:

[0163] The terminal does not reset the triggering time when the first target beam changes and the first target beam satisfies a first condition;

[0164] The first condition is at least one of the following:

[0165] E-1 item: the measurement result of the first target beam after the change satisfies the triggering condition.

[0166] E-2 item: the first target beam changes from the first beam to the second beam, and the measurement value of the first target beam does not change.

[0167] E-3: The first target beam changes from a first beam to a second beam, and the type configuration of the reference signal of the first target beam does not change. For example, the first target beam changes from beam A to beam B, but the type configuration of the reference signal of beam A is SSB, and the type configuration of the reference signal of beam B is also SSB, and the type configuration of the reference signal of the first target beam does not change, which is considered to satisfy the first condition.

[0168] Specifically, after the UE judges that the trigger event occurs, a first timer (used to calculate whether the trigger condition is met) is started, and the value of a first counter (initial value is 0, used to calculate the number of times the trigger condition is met) is increased by 1. In the next measurement, if the measurement result of the first target beam still meets the trigger condition of the trigger event, and the duration is higher than the trigger time TTT, the value of the first counter is increased by 1. In the case where the number of times K that the trigger condition is met calculated by the first counter is greater than or equal to M, and the time whether the trigger condition is met calculated by the first timer does not exceed T, the trigger beam measurement reporting or condition LTM is judged. In this process, if the first target beam changes, and the first target beam does not meet the first condition, the trigger time TTT is recalculated (the duration that the measurement result of the changed first target beam meets the trigger condition of the trigger event is recalculated whether it is higher than TTT). If the first target beam meets the first condition, TTT does not need to be recalculated. For example, when beam A is the first target beam, and TTT is 1 ms, before beam A changes, the trigger time of beam A is 0.5 ms, and after beam A changes (and meets the first condition), the trigger time is continued to be calculated on the basis of 0.5 ms, that is, the duration exceeds 0.5 ms (that is, the total duration exceeds TTT), and the value of the first counter is increased by 1.

[0169] Embodiment three,

[0170] The embodiment describes the specific implementation of item C-7 in the first operation in the case where the first target beam changes, that is, the terminal needs to determine whether to reset the offset value when the first target beam changes. The specific content is as follows:

[0171] In an optional embodiment, the terminal performs at least one first operation when the first target beam changes, including:

[0172] F-1: When the first target beam changes, and the first indication information sent by the network side device is used to indicate that the first offset value is used, the terminal uses the first offset value to judge whether the measurement result before the change and the measurement result after the change of the first target beam meet the trigger condition;

[0173] In general, when the first target beam changes from the first beam to the second beam, such as from beam A to beam B, the terminal uses the offset corresponding to beam A to determine whether the trigger condition is met before the first target beam changes, and uses the new offset (i.e., the offset corresponding to beam B) to determine whether the trigger condition is met after the first target beam changes. If the first indication information is included in the measurement resource configuration information sent by the network device to the UE, the first indication information is used to indicate that the terminal uses the first offset, and then the UE uses the first offset to determine whether the trigger condition is met before and after the first target beam changes.

[0174] For example, the first target beam changes from beam A to beam B, and the first offset is used to determine whether the measurement result of beam A meets the trigger condition of the trigger event or whether the trigger condition LTM is met. After the first target beam changes to beam B, the UE does not reset the offset, and still uses the first offset to determine whether the measurement result of beam B meets the trigger condition of the trigger event or whether the trigger condition LTM is met.

[0175] F-2 item: When the first target beam changes, and the terminal uses the first offset to determine whether the measurement result of the first target beam before the change and the measurement result after the change meets the trigger condition LTM.

[0176] Specifically, if the first indication information is included in the measurement resource configuration information sent by the network device to the UE, the first indication information is used to indicate that the terminal uses the first offset, and then the UE uses the first offset to determine whether the measurement result of beam B meets the trigger condition LTM before and after the first target beam changes.

[0177] F-3 item: When the first target beam changes, and the second indication information sent by the network device is used to indicate that the offset is not reset, the terminal uses the second offset to determine whether the measurement result of the first target beam before the change and the measurement result after the change meets the trigger condition, and the second offset is the offset used by the terminal before the first target beam changes.

[0178] If the second indication information is included in the measurement resource configuration information sent by the network device to the UE, the second indication information is used to indicate that the terminal uses the second offset value, which is the offset value used by the UE before the change of the first target beam, and the UE does not reset the offset value before and after the change of the first target beam, but uses the offset value corresponding to the first target beam before the change (the second offset value) to determine whether the trigger condition of the trigger event is met or whether the trigger condition LTM is met.

[0179] For example, the first target beam changes from beam A to beam B, and when determining whether the measurement result of beam A meets the trigger condition of the trigger event or whether the trigger condition LTM is met, the second offset value corresponding to beam A is used for the determination, and after the first target beam changes to beam B, the UE does not reset the offset value, but still uses the second offset value to determine whether the measurement result of beam B meets the trigger condition of the trigger event or whether the trigger condition LTM is met.

[0180] F-4: When the first target beam changes and the terminal uses the second offset value to determine whether the measurement result before the change of the first target beam and the measurement result after the change of the first target beam meets the trigger condition LTM.

[0181] Specifically, if the second indication information is included in the measurement resource configuration information sent by the network device to the UE, the second indication information is used to indicate that the terminal uses the second offset value, which is the offset value used by the UE before the change of the first target beam, and the UE does not reset the offset value before and after the change of the first target beam, but uses the offset value corresponding to the first target beam before the change (the second offset value) to determine whether the trigger condition LTM is met.

[0182] Embodiment Four,

[0183] The embodiment describes a specific implementation manner for determining whether to reset the reporting times when the second target beam (the second target beam is a beam that triggers the UE to perform beam measurement reporting or condition LTM) changes during the process in which the UE meets the measurement reporting condition and performs measurement reporting. The specific content is as follows:

[0184] In an optional embodiment, the method further includes:

[0185] The terminal performs at least one second operation when the second target beam changes, the second target beam being a beam that triggers beam measurement reporting or condition LTM;

[0186] The terminal performs beam measurement reporting or performs condition LTM based on the parameter value after performing the at least one second operation, and the at least one second operation includes:

[0187] G-1 item: reset the reporting times;

[0188] G-2 item: do not reset the reporting times.

[0189] The reporting times X is included in the measurement reporting configuration information sent by the network side device to the UE, for example, the LTM-Report Amount parameter or LTM-number Of Reports Sent configured by the network side to the UE. The reporting times refers to the number of times of reporting that the UE needs to perform each time of measurement reporting, and when the number of times of reporting performed by the UE meets the reporting times of the measurement reporting configuration information (i.e. X times), the reporting is stopped.

[0190] When the measurement result of the second target beam meets the measurement reporting condition, triggering the UE to perform the measurement reporting process, the second target beam changes. In general, the reporting times is not reset (i.e. G-2 item in the second operation), so that the reporting is continued on the basis of the number of times of reporting already performed before the change of the second target beam, until the reporting times X indicated in the measurement reporting configuration information is reached. Thus, the reporting times is not reset due to the change of the beam, so that the terminal always meets the required reporting times and continues to perform the reporting. For example, within a certain time T after the triggering event occurs, the number K of times that the measurement result of the beam A meets the triggering condition of the triggering event is greater than or equal to M, the beam A is taken as the second target beam to trigger the UE to perform the measurement reporting, and after the UE reports 3 times, the second target beam changes from the beam A to the beam B. Then, the reporting times is not reset, and it is assumed that the reporting times indicated in the measurement reporting configuration information is 5 times. After the reporting is continued for 2 times, the reporting is stopped.

[0191] When the measurement result of the second target beam meets the measurement reporting condition, triggering the UE to perform the measurement reporting process, the measurement value of the second target beam or the type configuration of the reference signal changes (for example, the measurement value of the second target beam changes from RSRP to RSRQ). Then, the reporting times needs to be reset (i.e. G-1 item in the second operation), the number of times of reporting actually performed is cleared, and the reporting is performed again based on the changed second target beam, until the reporting times X indicated in the measurement reporting configuration information is reached. For example, within a certain time T after the triggering event occurs, the number K of times that the measurement result of the beam A meets the triggering condition of the triggering event is greater than or equal to M, the beam A is taken as the second target beam to trigger the UE to perform the measurement reporting, and after the UE reports 3 times, the type configuration of the reference signal of the second target beam changes from SSB to CSI-RS. Then, the reporting times is reset, and it is assumed that the reporting times indicated in the measurement reporting configuration information is 5 times. After the change of the second target beam, the reporting is continued for 5 times, and then the reporting is stopped.

[0192] In an optional implementation, the second target beam changes, including at least one of the following:

[0193] The second target beam changes from a third beam to a fourth beam.

[0194] A measurement value of the second target beam changes.

[0195] A type configuration of a reference signal corresponding to the second target beam changes.

[0196] A resource configuration of the reference signal corresponding to the second target beam changes.

[0197] In an optional implementation, the terminal performs beam measurement reporting based on a parameter value after performing the at least one second operation, including any of the following:

[0198] H-1: The terminal reports measurement results of one or more beams with best measurement results.

[0199] The beam with the best measurement result is any of the following:

[0200] A beam with the best measurement result among beams associated with a first candidate cell, the first candidate cell being one candidate cell in a cell set included in the measurement resource configuration information.

[0201] A beam with the best measurement result among beams associated with all candidate cells, the all candidate cells being all candidate cells in the cell set included in the measurement resource configuration information.

[0202] Specifically, when the UE reports measurement results, the UE reports measurement results of N best beams (N is configured by a network side or agreed by a protocol). There are two ways to determine the beam with the best measurement result: one is that after all beams of a certain cell (i.e., one candidate cell in the cell set included in the measurement resource configuration information) complete measurement, measurement results of N best beams associated with the cell are selected for reporting. The other is that after all beams belonging to the same measurement resource configuration information (i.e., all candidate cells in the cell set included in the measurement resource configuration information) complete measurement, measurement results of N best beams are selected for reporting. Wherein, each cell reports measurement results of at most L beams, L being an integer greater than 0.

[0203] H-2: The terminal reports measurement results of P beams satisfying a measurement result threshold, P being an integer less than or equal to N, N being a maximum reporting quantity.

[0204] Specifically, if the reported beam measurement result requires that the measurement result is greater than or equal to the measurement result threshold to be reported, when the measurement results of P beams in the measurement results of each beam meet the measurement result threshold, only the measurement results of the P beams are reported, and P needs to be less than or equal to N, N being the maximum number of reporting indicated in the measurement reporting configuration information sent by the network side device or the maximum number of reporting agreed by the protocol.

[0205] H-3: The terminal reports the measurement results of T beams that meet the measurement result threshold, and reports the measurement results of N-T beams that do not meet the measurement result threshold, T being an integer less than N.

[0206] Specifically, if the reported beam measurement result requires that the measurement result is greater than or equal to the measurement result threshold to be reported, when the measurement results of P beams in the measurement results of each beam meet the measurement result threshold, only the measurement results of the P beams are reported, and P needs to be less than or equal to N, N being the maximum number of reporting indicated in the measurement reporting configuration information sent by the network side device or the maximum number of reporting agreed by the protocol.

[0207] H-4: The terminal reports the measurement results of S beams that meet the measurement result threshold, and reports the measurement results of N-S beams associated with each of the second candidate cells, S being an integer less than N, and N-S second candidate cells being: candidate cells in the cell set contained in the measurement resource configuration information except for the candidate cells associated with the S beams.

[0208] Specifically, if the reported beam measurement result requires a measurement result threshold to be equal to or greater than the measurement result threshold to be reported, only S beams of the measurement results of the beams meet the measurement result threshold, and the UE reports the measurement results of N beams (i.e., the measurement results of the S beams that meet the measurement result threshold, and the measurement results of the N-S beams of the cell that do not have any beam to be reported). For example, the maximum reporting number is 10, and among the measurement results of the beams, the measurement results of 4 beams meet the measurement result threshold (measurement results 1, 2, 3, and 4). Then, from the cell set contained in the measurement resource configuration information, the cells (second candidate cells) associated with the beams that do not have the measurement results 1, 2, 3, and 4 are selected, and the measurement results of 6 beams (measurement results 5-10) are selected for reporting. The UE reports the measurement results of 4 beams (measurement results 1, 2, 3, and 4), and the measurement results of 6 beams of the second candidate cells (measurement results 5-10).

[0209] The measurement method proposed in the above embodiment is described through the following embodiments.

[0210] Embodiment One,

[0211] Embodiment One describes the process of taking Event Three as an example above, taking the beam with the highest RSRP in the measurement results of the beams as the first target beam, when the first target beam changes, the terminal performs the first operation, and judges whether the measurement result of the first target beam after the change meets the trigger condition based on the parameter value after performing the first operation. The specific steps are as follows:

[0212] Step 1: The network side sends the L1 measurement configuration information to the UE.

[0213] Step 2: The UE starts L1 measurement based on the L1 measurement configuration information, and measures the RSRP of X beams of the candidate cells, where the RSRP of beam A is the highest, and the UE also measures the beam used by the serving cell, called beam C.

[0214] Step 3: At time one, the measurement result of beam A is higher than that of beam C and the difference is greater than or equal to the first offset value, and at time two after TTT, the UE considers that Event Three meets (i.e., the UE judges that the trigger event occurs, and beam A is the first target beam), the UE starts the first timer, and at the same time, the UE increases the value of the first counter (initial value is 0) by one. Next time the beam A is measured, the measurement result of beam A is still higher than that of beam C and the difference is greater than or equal to the first offset value (and the time of being higher exceeds TTT), the UE continues to increase the value of the first counter by one.

[0215] Step 4: At time three before the first timer expires, among the X beams of the candidate cell, beam A is no longer the beam with the highest RSRP, but beam B becomes the beam with the highest RSRP, and beam B still satisfies that the measurement result of beam B is higher than that of beam C and the difference is greater than or equal to the first offset value (i.e., the first target beam changes from beam A to beam B), the UE does not restart or stop the first timer but continues to run the first timer (i.e., performs item C-1: continues to calculate the time for whether the triggering condition is satisfied).

[0216] The UE can perform the following step 5a or step 5b:

[0217] Step 5a: The UE starts a new second counter to recalculate the number of times that beam B satisfies the event triggering condition. After the second timer expires (i.e., a certain time T is reached), if the total number of times that beam A + beam B satisfies the event triggering condition is greater than or equal to M times, the measurement reporting is triggered. In this case, the UE can further report the number of times that beam A and beam B satisfy, respectively, when the measurement reporting is performed (i.e., the number of times calculated by the first counter and the number of times calculated by the second counter are reported, respectively).

[0218] Step 5b: The UE continues to use the original first counter to continue to calculate the number of times that beam B satisfies the event triggering condition (i.e., performs item C-2: continues to calculate the number of times that the triggering condition is satisfied). After the first timer expires, if the first counter shows that the number of times that the event triggering condition is satisfied is greater than or equal to M times, the measurement reporting is triggered.

[0219] Embodiment two,

[0220] Embodiment two describes the process of performing the first operation by the terminal, judging whether the measurement result of the first target beam after the change satisfies the triggering condition based on the parameter value after the first operation is performed, taking the beam with the highest RSRP in the measurement result when the triggering is first triggered as the first target beam, and the first target beam changes.

[0221] Steps 1-3 are the same as in Embodiment one and are not repeated here.

[0222] Step 4: At time three before the first timer expires, among the X beams of the candidate cell, beam A is no longer the beam with the highest RSRP (i.e., the first target beam changes), the UE always uses beam A to make the judgment, and does not reset the first timer and the first counter, i.e., the UE performs the first operation (corresponding to item D-2 in the above embodiment one: does not recalculate the time for calculating whether the triggering condition is satisfied, and does not recalculate the number of times that the triggering condition is satisfied).

[0223] Step 5: After the first timer expires (i.e. a certain time T is reached), if the first counter shows that the number of times that the event triggering condition is met is greater than or equal to M times, the measurement reporting is triggered.

[0224] Embodiment Three,

[0225] Embodiment Three describes the process that when the original beam (the beam that first meets the triggering condition of the triggering event) no longer meets the condition, a new beam is used as the first target beam, the terminal performs the first operation, and based on the parameter value after performing the first operation, whether the measurement result of the first target beam after the change meets the triggering condition of the triggering event. The specific steps are as follows:

[0226] Steps 1-3 are the same as Embodiment One, and are not repeated here.

[0227] Step 4: At time three before the first timer expires, among the X beams of the candidate cell, beam A no longer meets the condition that the measurement result of beam A is higher than that of beam C and the difference is greater than or equal to the first offset value, and at this time, beam B meets the condition that the measurement result of beam B is higher than that of beam C and the difference is greater than or equal to the first offset value (i.e. the first target beam changes from beam A to beam B). Beam B can be the beam with the highest RSRP among the X beams of the candidate cell (i.e. the beam with the best measurement result) or any beam among the X beams. The UE does not restart or stop the first timer but continues to run the first timer (i.e. performs item C-1: continue to calculate the time whether the triggering condition is met).

[0228] The UE can perform the following step 5a or step 5b:

[0229] Step 5a: The UE starts a new second counter to recalculate the number of times that beam B meets the event triggering condition. After the second timer expires (i.e. a certain time T is reached), if the total number of times that beam A + beam B meets the event triggering condition is greater than or equal to M times, the measurement reporting is triggered. In this case, the UE can further report the number of times that beam A and beam B meet respectively when reporting the measurement (i.e. report the number of times calculated by the first counter and the number of times calculated by the second counter respectively).

[0230] Step 5b: The UE continues to use the original first counter to continue to calculate the number of times that beam B meets the event triggering condition (i.e. perform item C-2: continue to calculate the number of times that the triggering condition is met). After the first timer expires, if the first counter shows that the number of times that the event triggering condition is met is greater than or equal to M times, the measurement reporting is triggered.

[0231] Embodiment Four,

[0232] Embodiment four describes that in the process of terminal performing measurement reporting, the second target beam changes, the UE performs a second operation, and the UE performs measurement reporting based on the parameter value after performing the second operation, taking event three described above as an example. The specific steps are as follows:

[0233] Step 1: The network side device sends the L1 measurement configuration information to the UE.

[0234] Step 2: The UE starts L1 measurement based on the L1 measurement configuration information. The UE measures the RSRP of X beams of the candidate cell, wherein the RSRP of beam A is the highest, and the UE also measures the beam (for example, the beam associated with the indicated TCI state) used by the serving cell, which is called beam C.

[0235] Step 3: At time one, the measurement result of beam A is higher than that of beam C and the difference is greater than or equal to the first offset value. At time two after TTT, the UE considers that event three is met (beam A as the second target beam triggers beam measurement reporting), and the UE triggers measurement reporting and reports the measurement result of beam A to the network side device.

[0236] Step 4: If the measurement reporting configuration information sent by the network side device to the UE contains the reporting number L, and the current measurement reporting number for beam A is less than L, the UE starts the periodic reporting timer. After the time length of the periodic reporting timer, the terminal performs the next reporting, and continues to wait for the time length of the periodic reporting timer, and then performs the next reporting, until the reporting number is equal to L. When the reporting number has not reached L times, if beam A is no longer the beam with the highest RSRP, but beam B becomes the beam with the highest RSRP, and beam B still meets the condition that the measurement result of beam B is higher than that of beam C and the difference is greater than or equal to the first offset value (that is, the second target beam changes from beam A to beam B), the terminal reports the measurement result of beam B when performing the next reporting, and the reporting number continues to be calculated without being reset (that is, performing item G-2 in embodiment four: not resetting the reporting number). After reaching the reporting number L, stop reporting.
