Specifically, measurement event 2 indicates that the beam signal quality of the serving cell is lower than a preset threshold 1; measurement event 3 indicates that the beam signal quality of the candidate cell is higher than the beam signal quality of the serving cell by a preset offset; measurement event 4 indicates that the beam signal quality of the candidate cell is higher than a preset threshold 2; and measurement event 5 indicates that the beam signal quality of the serving cell is lower than the preset threshold 1 and the beam signal quality of the candidate cell is higher than the preset threshold 2.

[0036] Further, the second evaluation object further includes the first beam. The technical solution of the present application measures the beam before adjustment and the beam after adjustment, which can more comprehensively realize the measurement of the beam and further improve the switching efficiency.

[0037] Further, in the case where the measurement event is only associated with the serving cell, the terminal device deletes the measurement report for the first beam. In the technical solution of the present application, after the terminal device adjusts the evaluation object, the measurement report for the first beam has no reference value for the network device to decide the cell switching, and therefore the terminal device can delete the measurement report to avoid unnecessary data transmission and improve the communication efficiency.

[0042] The communication system to which the embodiments of the present application are applicable includes, but is not limited to, a Long Term Evolution (LTE) system, a 5th-Generation (5G) system, a New Radio (NR) system, and a future evolution system or a plurality of communication fusion systems.

The technical solutions of the present application are also applicable to different network architectures, including but not limited to a relay network architecture, a dual connectivity architecture, a vehicle-to-everything (V2X) architecture, and the like.

[0043] The present application mainly relates to communication between a terminal device and a network device. Among them:

[0044] The network device in the embodiments of the present application can also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device). The network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the device providing the base station function in the second generation (2nd-Generation, 2G) network includes a base transceiver station (BTS), the device providing the base station function in the third generation (3rd-Generation, 3G) network includes a node B (NodeB), the device providing the base station function in the fourth generation (4th-Generation, 4G) network includes an evolved node B (eNB), in a wireless local area network (WLAN), the device providing the base station function is an access point (AP), the device providing the base station function in the NR includes a next generation node base station (gNB), and a continuously evolved node B (ng-eNB), wherein the gNB and the terminal device communicate with each other using NR technology, the ng-eNB and the terminal device communicate with each other using evolved universal terrestrial radio access (E-UTRA) technology, and the gNB and the ng-eNB are both connected to a 5G core network. The network device in the embodiments of the present application also includes devices providing base station functions in future new communication systems and the like.

[0045] The terminal equipment in the embodiments of the present application can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal equipment in a future 5G network or a terminal equipment in a future evolved Public Land Mobile Network (PLMN), etc. The embodiments of the present application are not limited thereto. The terminal equipment can also be referred to as user equipment (User Equipment, UE), terminal, etc.

[0046] As described in the background, the serving cell of the terminal equipment, the beam of the serving cell and the beam of the candidate cell can change. How to realize the adjustment of the measurement beam in the measurement event is a technical problem to be solved.

[0047] Specifically, in the case that the serving cell of the terminal equipment and the beam of the serving cell change, the network equipment can adjust the measurement beam of the LTM measurement event through the Radio Resource Control (RRC) message, resulting in large signaling overhead and being unable to respond to the change of the serving beam in time.

[0048] In the technical solution of the present application, when the serving beam or the activated beam of the cell to be measured changes or is newly added, the terminal equipment can actively adjust the first evaluation object corresponding to the measurement event, thereby reducing the signaling overhead and being able to respond to the change of the serving beam or the activated beam in time; and by measuring the at least one second beam changed or newly added, the evaluation effect of the measurement event can be ensured, thereby improving the switching efficiency and effect.

[0049] In the embodiments of the present application, in order to ensure service continuity, the change of the serving cell occurring in the mobile process of the terminal equipment in the RRC connected state can also be referred to as mobility.

[0050] In the embodiments of the present application, the mobility switching triggered by layer 1 and / or layer 2 can also be referred to as L1 / L2 switching, low-layer switching, low-layer triggered switching, etc., because the traditional switching is layer 3 triggered switching.

[0051] Specifically, the LTM procedure is that the network device configures one or more candidate cells based on the measurement report (for example, a radio resource management (RRM) measurement report or a layer 3 (L3) measurement report) reported by the terminal device, and provides the terminal device with pre-configuration information of the one or more candidate cells (which can be referred to as LTM candidate cells) and an LTM-related measurement event through an RRC message. After receiving the pre-configuration information and the LTM-related measurement event from the network device, the terminal device evaluates the candidate cells, and sends a measurement report (for example, a layer 1 measurement report) to the network device when a reporting condition is met, so that the network device decides to trigger an LTM handover based on the measurement report reported by the terminal device. The network device sends an LTM handover command to the terminal device through layer 2 signaling, so that the terminal device performs a handover procedure.

[0052] In the embodiments of the present application, the measurement event can also be an LTM Event (LTM measurement event) or an L1 Event (layer 1 event), or can be any other implementable name, which is not limited in the present application.

[0053] In the embodiments of the present application, the measurement can be divided into beam-level measurement and cell-level measurement. The beam-level measurement refers to that the network device can configure the terminal device to measure and report one or more beam-related information of a cell, for example, a beam identifier and / or a beam measurement result. The cell-level measurement refers to that the terminal device performs weighting processing such as averaging processing or maximum value processing on the measurement result (for example, a power value) of one or more beams of a cell to obtain the measurement result of the cell according to the configuration of the network device.

[0054] Specifically, the beam-level measurement includes measuring at least one of the following reference signals: synchronization signal and PBCH block (SSB) measurement, channel state information-reference signal (CSI-RS). The SSB can be composed of three parts of primary synchronization signals (PSS), secondary synchronization signals (SSS) and PBCH.

[0055] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] Reference is made toFigure 1 The method provided in the application specifically comprises the following steps:

[0057] Step 101: The terminal device adjusts a first evaluation object corresponding to a measurement event to obtain a second evaluation object.

[0058] In the embodiment, the terminal device is configured with a to-be-measured cell and a measurement event. In the case where the serving beam or the activated beam of the to-be-measured cell is changed from a first beam to one or more second beams or one or more second beams are newly added, the terminal device performs step 101.

[0059] In specific implementation, the measurement event is to evaluate the measurement object, and the evaluation object represents a beam in a cell, such as a serving beam or an activated beam. The first evaluation object represents the measurement beam before the to-be-measured cell is adjusted, and the second evaluation object represents the measurement beam after the to-be-measured cell is adjusted.

[0060] Step 102: The terminal device sends a measurement report to a network device. Correspondingly, the network device receives the measurement report. The terminal device reports the measurement report when the evaluation object meets the measurement event, or the terminal device reports the measurement report after the evaluation object meets the measurement event for a period of time, or the terminal device periodically reports the measurement report when the evaluation object meets the periodic reporting condition.

[0061] Specifically, the measurement event can include measurement event 2 (or LTM Event2) to measurement event 5 (LTM Event5). The measurement event 2 indicates that the beam signal quality of the serving cell is lower than a preset threshold 1; the measurement event 3 indicates that the beam signal quality of the candidate cell is higher than the beam signal quality of the serving cell by a preset offset; the measurement event 4 indicates that the beam signal quality of the candidate cell is higher than or equal to a preset threshold 2; and the measurement event 5 indicates that the beam signal quality of the serving cell is lower than the preset threshold 1 and the beam signal quality of the candidate cell is higher than or equal to the preset threshold 2.

[0062] It should be noted that the application does not limit the size of the measurement event and the various thresholds involved in the above measurement event.

[0063] In specific implementation, the to-be-measured cell can be a serving cell, a candidate cell, or a serving cell and a candidate cell. That is, the measurement event can be associated with only the serving cell, such as the measurement event 2. The measurement event can be associated with only the candidate cell, such as the measurement event 4. The measurement event can be associated with the serving cell and the candidate cell, such as the measurement event 3 and the measurement event 5. The serving cell can be a primary cell PCell or a primary secondary cell PSCell, that is, the embodiment of the application can be applied to a non-dual connection scenario and a dual connection scenario.

[0064] In this embodiment, the terminal device can actively adjust the first evaluation object corresponding to the measurement event when the serving beam or the activated beam of the to-be-measured cell changes or is newly added, thereby reducing signaling overhead and responding to changes in the serving beam or the activated beam in a timely manner; and by measuring the at least one second beam changed or newly added, the evaluation effect of the measurement event can be ensured, thereby improving the switching efficiency and effect.

[0065] According to different measurement events, the beam change in this embodiment can include the following cases:

[0066] Case 1: The measurement event is only associated with a serving cell, and the serving beam of the serving cell changes from a first beam to one or more second beams.

[0067] Case 2: The measurement event is only associated with a serving cell, and one or more second beams are newly added to the serving beam of the serving cell.

[0068] Case 3: The measurement event is only associated with a serving cell, and the activated beam of the serving cell changes from a first beam to one or more second beams.

[0069] Case 4: The measurement event is only associated with a serving cell, and one or more second beams are newly added to the activated beam of the serving cell.

[0070] Case 5: The measurement event is only associated with a candidate cell, and the activated beam of the candidate cell changes from a first beam to one or more second beams.

[0071] Case 6: The measurement event is only associated with a candidate cell, and one or more second beams are newly added to the activated beam of the candidate cell.

[0072] Case 7: The measurement event is associated with a serving cell and a candidate cell, the serving beam of the serving cell changes from a first beam to one or more second beams, or one or more second beams are newly added, and the activated beam of the candidate cell remains unchanged.

[0073] Case 8: The measurement event is associated with a serving cell and a candidate cell, the serving beam of the serving cell remains unchanged, and the activated beam of the candidate cell changes from a first beam to one or more second beams or one or more second beams are newly added.

[0074] Case 9: The measurement event is associated with a serving cell and a candidate cell, the serving beam of the serving cell changes from a first beam to one or more second beams, or one or more second beams are newly added, and at the same time, the activated beam of the candidate cell changes from a first beam to one or more second beams or one or more second beams are newly added.

[0075] In each of the above cases, the first beam of the serving cell and the first beam of the candidate cell are different, and the second beam of the serving cell and the second beam of the candidate cell are different.

[0076] The following describes how to adjust the evaluation object of the measurement event under specific beam change conditions in combination with specific embodiments.

[0077] Embodiment 1, corresponding to case 1, one or more control resource sets (CORESETs) are configured for the serving cell, and the transmission configuration indication (TCI) of each CORESET corresponds to a service beam that changes from the first beam to the second beam. Here, the service beam corresponding to the TCI refers to the reference signal of the service beam as the basis for the TCI, and the network device can configure the TCI and the reference signal in the beam, such as SSB or CSI-RS, to be quasi co-located (QCL).

[0078] In this embodiment, the second evaluation object can include any of the following:

[0079] The second beam corresponding to the transmission configuration indication of each CORESET;

[0080] The beam corresponding to the transmission configuration indication of the CORESET with the smallest index;

[0081] The beam corresponding to the transmission configuration indication of the CORESET with the smallest index except for CORESET 0;

[0082] The second beam with the best signal quality corresponding to the transmission configuration indication of the CORESET.

[0083] In the case where the second evaluation object is the second beam corresponding to the transmission configuration indication of each CORESET, the terminal device can measure the second beam corresponding to the transmission configuration indication of each CORESET and evaluate according to the measurement event, thereby achieving comprehensive evaluation and assisting the network device in switching.

[0084] The network device can configure one or more CORESETs for the terminal device in the serving cell, and different CORESETs can apply the same TCI or different TCIs. In some scenarios, the network device can further configure a pool index (coresetPoolIndex) for the CORESET, which can take values of 0 or 1, and apply different transmission configuration indications. When the network device configures the pool index of the CORESET to include 0 and 1, the second evaluation object can include any of the following:

[0085] The transmission configuration indication of the pool index 0 and 1 of all CORESETs respectively corresponds to the second beam, or only the transmission configuration indication of the pool index 0 corresponds to the second beam;

[0086] The transmission configuration indication of the pool index 0 and 1 of the CORESET with the smallest index (including CORESET 0 or not including CORESET 0) respectively corresponds to the second beam, or the transmission configuration indication of the pool index 0 of the CORESET with the smallest index (including CORESET 0 or not including CORESET 0) corresponds to the second beam;

[0087] The transmission configuration indication of the pool index 0 and 1 of the CORESET respectively corresponds to the second beam with the best signal quality, or the transmission configuration indication of the pool index 0 of the CORESET corresponds to the second beam with the best signal quality.

[0088] For example, due to the movement of the terminal device, the serving cell sends signaling such as a Medium Access Control (MAC) Control Element (CE) to the terminal device to modify the transmission configuration indication of the CORESET, and changes the TCI of the CORESET 1 from the synchronization signal block (SSB) 3 to the SSB 4, that is, the reference signal of the QCL of the Demodulation Reference Signal (DMRS) of the Physical Downlink Control Channel (PDCCH) mapped to the search space of the CORESET 1 is the SSB 4. At this time, the terminal device adjusts the beam corresponding to the first evaluation object SSB 3 to the beam corresponding to the second evaluation object SSB 4.

[0089] Among them, the CORESET with the smallest index is usually more important and undertakes more functions. Therefore, the terminal device can continue to measure and evaluate the beam corresponding to the transmission configuration indication of the CORESET with the smallest index as the second evaluation object.

[0090] For example, the serving cell configures the terminal device with the CORESET 1 and the CORESET 2, and the serving cell modifies the TCI of the two CORESETs by modifying the MAC CE of the CORESET TCI, changes the TCI of the CORESET 1 from the SSB 4 to the SSB 6, and changes the TCI of the CORESET 2 from the SSB 5 to the SSB 7. At this time, the terminal device actively adjusts the second evaluation object from the beam corresponding to the SSB 4 to the beam corresponding to the SSB 6, that is, the terminal device takes the TCI of the CORESET with the smallest index as the second evaluation object.

[0091] For example, the serving cell configures CORESET 1 and CORESET 2 for the terminal device, and the serving cell modifies the TCIs of the two CORESETs by modifying the MAC CE of the CORESET TCI, changes the TCI of CORESET 1 from SSB 4 to SSB 6, and changes the TCI of CORESET 2 from SSB 5 to SSB 7. After measurement, the terminal device finds that the signal quality of SSB 7 is better than that of SSB 6. In this case, the terminal device actively adjusts the second evaluation object from the beam corresponding to SSB 4 to the beam corresponding to SSB 7, that is, the terminal device takes the second beam with the best signal quality corresponding to the TCI of the CORESET as the second evaluation object.

[0092] By taking the second beam with the best signal quality as the second evaluation object, the embodiment of the application can improve the accuracy of evaluation of the serving cell, so that the network device can be assisted to switch to a better cell in time when the service quality of the serving cell deteriorates, and the communication quality is improved.

[0093] It should be noted that the TCI in the application can be based on SSB or CSI-RS, and the application does not limit this.

[0094] In the case 1 of embodiment 2, the serving beam of the serving cell changes from the first beam to the beam selected in the beam failure recovery process when the serving cell initiates the beam failure recovery.

[0095] In the embodiment, the second evaluation object includes the beam selected in the beam failure recovery process.

[0096] For example, the terminal device finds that the beam fails, initiates the beam failure recovery process, and selects SSB 10 as the SSB for initiating the beam failure recovery request. After the recovery is successful, the terminal device actively adjusts the evaluation object of the measurement event to SSB 10. That is, at this time, the terminal device takes the beam corresponding to SSB 10 as the evaluation object when evaluating the measurement event, and starts to evaluate again.

[0097] By evaluating the beam selected in the beam failure recovery process, the embodiment can evaluate the beam providing communication services for the terminal device in time, and assist the network device to make better switching decisions.

[0098] In a variation of embodiment 2, when the terminal device initiates the beam failure recovery procedure (e.g., sends a beam failure recovery request), the measurement task related to the LTM measurement event is suspended, i.e., the beams of the serving cell and / or the candidate cell are not evaluated, and the LTM measurement event is executed again, i.e., the LTM event measurement task is resumed, after the terminal device receives the RRC reconfiguration message sent by the network device (i.e., the first RRC reconfiguration message after the beam failure recovery procedure, which can modify the LTM measurement task or maintain the current LTM measurement task), to evaluate the beams of the serving cell and the candidate cell.

[0099] In embodiment 3, corresponding to case 1, the serving cell is changed from the first cell to the second cell in the case of performing cell switching.

[0100] In this embodiment, the serving beam is changed from the first beam of the first cell to the beam selected in the process of accessing the second cell, and the second evaluation object includes the beam selected in the process of accessing the second cell.

[0101] For example, the terminal device performs switching, such as switching to a neighboring cell, and selects the SSB with the strongest signal strength to initiate the random access procedure in the switching process to access the target cell (i.e., the second cell). If the LTM configuration is included in the switching command, i.e., the new LTM candidate cell and the LTM measurement event, such as measurement event 2, the terminal device uses the beam accessed in the switching process as the second evaluation object of event 2.

[0102] It should be noted that the terminal device can also select the SSB with the second strongest signal strength to initiate the random access procedure, in which case the second evaluation object is the beam corresponding to the SSB with the second strongest signal strength; or when the signal strengths of multiple SSBs all exceed the threshold, the terminal device randomly selects an SSB to initiate the random access procedure, in which case the second evaluation object is the beam corresponding to the randomly selected SSB, which is not limited by the present application.

[0103] In a variation of embodiment 3, when the terminal device initiates the random access procedure (e.g., sends a random access request), the measurement task related to the LTM measurement event is suspended, i.e., the beams of the serving cell and / or the candidate cell are not evaluated, and the LTM measurement event is executed again, i.e., the LTM event measurement task is resumed, after the terminal device receives the RRC reconfiguration message sent by the network device (i.e., the first RRC reconfiguration message after the cell switching is completed, which can modify the LTM measurement task or maintain the current LTM measurement task), to evaluate the beams of the serving cell and the candidate cell.

[0104] Example 4, corresponding to Case 2, involves adding at least one second CORESET to the control resource set (CORESET) configured for the serving cell. The transmission configuration indications of the at least one second CORESET correspond to one or more second beams.

[0105] In this embodiment, the second evaluation object includes any one of the following:

[0106] The transmission configuration of the first CORESET indicates the corresponding first beam;

[0107] The first beam corresponding to the transmission configuration indication of the first CORESET and the second beam corresponding to the transmission configuration indication of the at least one second CORESET;

[0108] The transmission configuration of the CORESET with the smallest index indicates the corresponding beam;

[0109] The transmission configuration of the CORESET with the smallest index other than CORESET 0 indicates the corresponding beam.

[0110] The beam with the best signal quality among the first and second beams.

[0111] Among them, the terminal equipment can continue to use the first beam corresponding to the transmission configuration indication of the first CORESET as the second evaluation object.

[0112] For example, if a terminal device is configured with CORESET1, and the network device configures a new CORESET 2 for the terminal device in the serving cell, the TCI of CORESET2 is SSB5, while the TCI of the original CORESET1 remains SSB4. The terminal device can still continue to measure the beam corresponding to SSB4.

[0113] In addition, the terminal device can also select the beam with the best signal quality between the first beam and the second beam as the second evaluation object.

[0114] For example, a terminal device is configured with CORESET1. The network device configures a new CORESET, CORESET2, in the serving cell for the terminal device. The TCI of CORESET2 is SSB5, while the TCI of the original CORESET1 remains SSB4. After measurement, the terminal device finds that the signal quality of SSB5 is better than that of SSB4. The terminal device then evaluates the beam corresponding to SSB5 according to the measurement event.

[0115] The embodiments of the present application can realize the accuracy of service cell evaluation by taking the second beam with the best signal quality as the second evaluation object, so as to assist the network device to switch to a better cell in time when the service quality of the service cell deteriorates, and improve the communication quality.

[0116] In embodiment 5, corresponding to case 3 and case 4, the activated beam of the service cell is changed from the first beam corresponding to the first transmission configuration indication to one or more second beams corresponding to one or more second transmission configuration indications, or one or more second beams are added.

[0117] In the embodiment, the second evaluation object includes any of the following:

[0118] one or more second beams;

[0119] the second beam corresponding to the second transmission configuration indication with the smallest index;

[0120] the second beam corresponding to the second transmission configuration indication with the largest index;

[0121] the second beam with the best signal quality.

[0122] In the embodiment, the service cell, for example, the primary cell (Pcell) in the carrier aggregation scenario, can modify the downlink TCI of the service cell or simultaneously modify the uplink and downlink TCIs of the service cell by the MAC CE, for example, the unified TCI state activation / deactivation MAC CE (Unified TCI States Activation / Deactivation MAC CE). The new MAC CE indicates that the service cell has multiple activated second TCIs.

[0123] In the embodiment, the terminal device can take all the second beams as the second evaluation object.

[0124] In the embodiment, the terminal device can also take the second beam corresponding to the second transmission configuration indication with the smallest or largest index as the second evaluation object.

[0125] In the embodiment, the terminal device can take the second beam with the best signal quality in all the second beams as the second evaluation object.

[0126] In the above embodiments 1 to 5, if the terminal device has a measurement report to be transmitted for the first beam, the measurement report for the first beam is deleted.

[0127] In this embodiment, after the terminal device adjusts the evaluation object, the first beam no longer provides communication services for the terminal device or is no longer activated, and the measurement report for the first beam of the serving cell has no reference value for the network device to decide cell switching, so the terminal device can delete the measurement report to avoid unnecessary data transmission and waste of wireless resources, and improve communication efficiency.

[0128] In embodiment 6, corresponding to case 5 and case 6, the activated beam of the candidate cell changes to add one or more second beams corresponding to one or more third transmission configuration indications.

[0129] In this embodiment, the second evaluation object includes any of the following:

[0130] One or more second beams;

[0131] The second beam corresponding to the third transmission configuration indication with the smallest index;

[0132] The second beam corresponding to the third transmission configuration indication with the largest index;

[0133] The second beam with the best signal quality.

[0134] In this embodiment, the terminal device can take all the second beams as the second evaluation object.

[0135] In this embodiment, the terminal device can also take the second beam corresponding to the second transmission configuration indication with the smallest or largest index as the second evaluation object.

[0136] In this embodiment, the terminal device can take the second beam with the best signal quality among all the second beams as the second evaluation object.

[0137] For example, the candidate cell has Cell2 and Cell3, and the serving cell (Cell1) can modify the activated TCI of the candidate cell through the candidate cell TCI state activation / deactivation MAC CE (Candidate Cell TCI States Activation / Deactivation MAC CE). After the terminal device discovers that the activated TCI changes, the terminal device takes the beam corresponding to the new activated TCI as the second evaluation object for evaluation. If the candidate cell activates multiple TCIs, the terminal device evaluates the SSB / CSI-RS corresponding to the multiple TCIs, and reports the measurement report under the condition of meeting the respective measurement event 3 reporting conditions.

[0138] In the above embodiment 6, if the terminal device has a measurement report to be transmitted for the first beam, the measurement report for the first beam is reported.

[0139] For example, if the TCI of the candidate cell changes, but the terminal device has obtained a measurement report based on the original measurement beam, such as the beam corresponding to SSB3 before the TCI changes, and the newly activated TCI after the TCI changes is based on SSB4, if the terminal device has generated an L1 measurement report of SSB3, the terminal device continues to report the measurement report.

[0140] In this embodiment, after the terminal device adjusts the evaluation object, since each beam of the candidate cell will affect the handover decision, the measurement report of the first beam has reference value for the network device to make a cell handover decision, and therefore the terminal device can report the measurement report to assist the network device in making a handover decision.

[0141] Embodiment 7, corresponding to case 7, the second evaluation object includes the activated beam of the candidate cell, and the second evaluation object includes one or more second beams, or the second beam with the best signal quality in the plurality of second beams.

[0142] In this embodiment, the measurement event is associated with the serving cell and the candidate cell, and therefore the measurement beam in the second evaluation object includes the beam in the serving cell and the beam in the candidate cell.

[0143] Since the activated beam of the candidate cell does not change, the measurement beam on the candidate cell in the second evaluation object does not change. Since the serving beam of the serving cell changes, the terminal device needs to adjust the beam of the serving cell in the second evaluation object. That is, the second evaluation object includes all second beams in the serving cell, or the second beam with the best signal quality in the plurality of second beams.

[0144] The specific implementation of how to adjust the second evaluation object in the case of the change of the beam of the serving cell can refer to the foregoing embodiments 1 to 5, which will not be described here again.

[0145] Embodiment 8, corresponding to case 8, the second evaluation object includes the serving beam of the serving cell, and the second evaluation object further includes one or more second beams of the candidate cell, or the second beam with the best signal quality in the plurality of second beams of the candidate cell.

[0146] In this embodiment, the measurement event is associated with the serving cell and the candidate cell, and therefore the measurement beam in the second evaluation object includes the beam in the serving cell and the beam in the candidate cell.

[0147] Since the serving beam of the serving cell does not change, the measurement beam on the serving cell in the second evaluation object does not change. Since the activated beam of the candidate cell changes, the terminal device needs to adjust the beam of the candidate cell in the second evaluation object. That is, the second evaluation object includes all second beams in the candidate cell, or the second beam with the best signal quality in the plurality of second beams.

[0148] For example, the terminal device is configured with measurement event 3 (indicating that the signal quality of the beam of the candidate cell is higher than that of the serving cell by a preset offset), the serving beam of the serving cell does not change, and the active beam of a certain candidate cell changes from SSB3 to SSB4 and SSB5. At this time, the terminal device needs to evaluate the signal quality difference between SSB4 and the serving beam of the serving cell, and the signal quality difference between SSB5 and the serving beam of the serving cell. As long as any one (SSB4 or SSB5) is higher than the signal quality of the serving beam of the serving cell by a preset offset (optionally for a period of time), the terminal device needs to report a measurement report. If SSB4 and SSB5 both meet the reporting condition, the measurement results of SSB4 and SSB5 need to be reported at the same time.

[0149] For how to adjust the second evaluation object when the beam of the candidate cell changes, refer to the foregoing embodiment 6, which will not be repeated here.

[0150] Embodiment 9, corresponding case 9, the second evaluation object includes one or more second beams of the serving cell, or the second beam with the best signal quality in the plurality of second beams, and the second evaluation object further includes one or more second beams of the candidate cell, or the second beam with the best signal quality in the plurality of second beams of the candidate cell.

[0151] Different from the foregoing embodiments 7 and 8, in this embodiment, the serving beam of the serving cell and the active beam of the candidate cell both change, so the terminal device needs to adjust the beam of the serving cell and the measurement beam of the candidate cell in the second evaluation object.

[0152] For example, the terminal device is configured with measurement event 3 (indicating that the signal quality of the beam of the candidate cell is higher than that of the serving cell by a preset offset), the serving beam of the serving cell changes from SSB2 to SSB4 and SSB5, and the active beam of a certain candidate cell changes from SSB6 to SSB7 and SSB8. At this time, the terminal device needs to evaluate the signal quality difference between SSB7, SSB8 and the serving beam SSB4, SSB5 of the serving cell (including SSB7 to SSB4, SSB7 to SSB5, SSB8 to SSB4, SSB8 to SSB5), or the signal quality difference between SSB7, SSB8 and the serving beam with the best signal quality in the serving cell, or the difference between the beam with the best signal quality in SSB7 and SSB8 and the beam with the best signal quality in SSB4 and SSB5. As long as the preset offset is met (optionally for a period of time), the terminal device needs to report a measurement report.

[0153] In another embodiment of the present application, the network device can configure a measurement event for the terminal device through the measurement configuration information.

[0154] Please refer to Figure 2 In step 201, the network device sends the measurement configuration information to the terminal device, the measurement configuration information is used to configure a measurement event, and the measurement event is a low-layer handover related measurement event. Accordingly, the terminal device receives the measurement event.

[0155] Specifically, the network device can carry the measurement configuration information through RRC signaling.

[0156] For example, the terminal device supports LTM handover, so the network device configures the candidate cells of LTM for the terminal device, and also configures the measurement events, such as LTM measurement event 2 and LTM measurement event 3.

[0157] Further, the measurement configuration information is also used to configure a first evaluation object, and the first evaluation object includes a first beam.

[0158] For example, when the network device initially configures the LTM measurement event through RRC, the serving cell configures the serving beam (i.e. the first beam) corresponding to measurement event 2 through RRC signaling, and the serving beam of the serving cell corresponding to measurement event 3 is also the beam corresponding to SSB3, and the beam of the candidate cell corresponding to measurement event 3 can be indicated through the measurement configuration information.

[0159] In step 202, the terminal device adjusts the first evaluation object corresponding to the measurement event to obtain a second evaluation object.

[0160] In step 203, the terminal device reports the measurement report.

[0161] It should be noted that the serial numbers of the steps in the present embodiment do not represent the limitation of the execution order of the steps.

[0162] It can be understood that, in specific implementation, the communication method can be realized in the form of a software program running in a processor integrated in a chip or a chip module. The method can also be realized in the form of software combined with hardware, and the present application does not make any limitation.

[0163] Those skilled in the art understand that the steps 202 and 203 can be regarded as execution steps corresponding to the steps 101 and 102 of the above-mentioned Figure 1 embodiment, and the two are complementary in specific implementation principles and logic. Therefore, the explanations of the terms involved in the present embodiment can refer to the related descriptions of the above-mentioned Figure 1 embodiment, which will not be repeated here.

[0166] In this embodiment, when the serving beam or the active beam of the to-be-measured cell is changed or newly added, the terminal device can actively adjust the first evaluation object corresponding to the measurement event, thereby reducing the signaling overhead. In addition, by measuring the at least one second beam after the change or the newly added second beam, the evaluation effect of the measurement event can be ensured, thereby improving the switching efficiency.
