It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0033] The following description, in conjunction with the accompanying drawings, details an event-triggered measurement method, apparatus, and terminal provided in this application through some embodiments and application scenarios.

[0034] Please refer to Figure 2, which is a flowchart of an event-triggered measurement method provided in an embodiment of this application. As shown in Figure 2, it includes the following steps:

[0035] Step 201: The terminal determines the target beam, which includes at least one of the following: the first beam of the serving cell and the second beam of the neighboring cell.

[0036] The first beam of the aforementioned serving cell can refer to the beam of a specific serving cell, which can be one or more beams.

[0037] The second beam of the aforementioned neighboring cell can refer to the beam of a specific neighboring cell, specifically one or more beams.

[0038] In this embodiment of the application, neighboring cells can also be understood as candidate cells.

[0039] Step 202: If the measurement result of the target beam satisfies the trigger event, the terminal trigger layer 1 shall report the measurement or execute conditional LTM.

[0040] The aforementioned triggering event can be a triggering event triggered by the terminal itself, which can be understood as an event that the terminal can trigger on its own, or the aforementioned triggering event can be a triggering event of the terminal's measurement results.

[0041] In this embodiment of the application, the triggering event does not require the participation of the network-side device. For example, it does not require receiving the Radio Resource Control (RRC) signaling sent by the network-side device to trigger LTM, or it does not require receiving the MAC CE from the network-side device to trigger LTM.

[0042] The specific content of the aforementioned triggering event can be either agreed upon in the protocol or pre-configured by the network-side device.

[0043] In some implementations, the triggering event reported by Layer 1 measurement and the triggering event of the execution condition LTM can be configured independently. That is, the triggering event reported by Layer 1 measurement and the triggering event of the execution condition LTM can be different events. For example, the triggering event reported by Layer 1 measurement is a normal triggering event, and the triggering event of the execution condition LTM is a conditional triggering event.

[0044] In some implementations, the triggering event for Layer 1 measurement reporting and the triggering event for execution condition LTM can be the same event.

[0045] In some implementations, the triggering event for the execution condition LTM may include at least one of the following:

[0046] Event 1: When the measurement result of the first beam of the serving cell is greater than or equal to the fourth threshold;

[0047] Event 2: When the measurement result of the first beam of the serving cell is <= the fifth threshold;

[0048] Event 3: When the measurement result of the second beam of the candidate cell is greater than or equal to the measurement result of the first beam of the serving cell, and the difference is greater than or equal to the first offset value;

[0049] Event 4: When the measurement result of the second beam of the candidate cell is greater than or equal to the first threshold, and the phase difference is greater than or equal to the second offset value;

[0050] Event 5: When the measurement result of the first beam of the serving cell is <= the second threshold and the measurement result of the second beam of the candidate cell is >= the third threshold.

[0051] The first threshold, second threshold, third threshold, fourth threshold, and fifth threshold mentioned above may be agreed upon by the protocol or configured by the network-side device, and the first offset value and second offset value mentioned above may be agreed upon by the protocol or configured by the network-side device.

[0052] In some implementations, the triggering events reported by the Layer 1 measurement may include at least one of the events one, two, three, four, and five. The values ​​of each threshold or offset in the triggering events reported by the Layer 1 measurement and the triggering events of the execution condition LTM may be the same or different.

[0053] In the embodiments of the present application, the event-triggered layer 1 measurement reporting or the execution condition LTM can be realized through the above steps, so that the terminal can timely perform layer 1 measurement reporting or execute LTM, and the terminal switching process can be avoided, thereby improving the communication performance of the terminal. For example, the inaccurate or delayed measurement reporting can be avoided, and the network side device cannot obtain appropriate measurement results, thereby affecting the subsequent switching process. In addition, through the event-triggered layer 1 measurement reporting or the execution condition LTM, the layer 1 measurement results that are too frequent and may not help the network side can be avoided, so as to save transmission resources.

[0054] As an optional implementation, the first beam of the serving cell includes one of the following:

[0055] a beam corresponding to a transmission configuration indicator (TCI) state indicated by the network side device; or

[0056] a beam determined based on the TCI state indicated by the network side device.

[0057] The TCI state indicated by the network side device can be a TCI state activated by the network side device, or a TCI state indicated by the network side device in the TCI state activated by the network side device. For example, a medium access control control element (MAC CE) activates multiple TCI states, and downlink control information (DCI) indicates one of the TCI states. In this case, the TCI state is the TCI state indicated by the network side device. If the MAC CE activates only one TCI state, the TCI state is the TCI state indicated by the network side device.

[0058] In some embodiments, the TCI state indicated by the network side device can be one or more TCI states.

[0059] The first beam including the beam corresponding to the TCI state indicated by the network side device can be that the beam corresponding to the indicated TCI state is used as the first beam regardless of whether the beam corresponding to the indicated TCI state is associated with a serving cell (i.e., the current cell) or a neighbor cell (also referred to as a candidate cell).

[0060] The beam determined based on the TCI state indicated by the network side device can be that the first beam is determined based on the TCI state indicated by the network side device. For example, the beam determined based on the TCI state indicated by the network side device includes one of the following:

[0061] In a case where the TCI state indicated by the network-side device is associated to the serving cell, a beam corresponding to the TCI state indicated by the network-side device; or

[0062] In a case where the TCI state indicated by the network-side device is associated to the neighboring cell, a beam corresponding to the TCI state indicated in a physical downlink control channel (PDCCH) associated to a first control resource set (CORESET) of the serving cell; or

[0063] In a case where the TCI state indicated by the network-side device is associated to the neighboring cell, a best beam or an arbitrary beam in beams corresponding to the activated TCI state of the serving cell.

[0064] In some embodiments, the configuration of the serving cell received by the terminal includes a control resource set pool index (CORESETPoolindex), and a control resource set with the CORESETPoolindex of 0 is the first control resource set.

[0065] In some embodiments, a physical cell identifier (PCI) included in an information element (IE) corresponding to a TCI state is associated to the serving cell, and the TCI state is associated to the neighboring cell when the PCI included in the IE corresponding to the TCI state corresponds to the neighboring cell.

[0066] The first CORESET can be CORESET#0.

[0067] The best beam can be a best beam in terms of L1-RSRP (Layer 1 reference signal received power) or L1-SINR (Layer 1 signal-to-noise and interference ratio).

[0068] The embodiments can determine the first beam of the serving cell according to the indicated TCI state associated cell, so that the first beam is more suitable for the terminal, and the reliability of the measurement trigger is improved.

[0069] In some embodiments, in the case that the network-side device indicates at least two TCI states, the beam corresponding to the TCI state indicated by the network-side device includes one of the following:

[0070] the beam corresponding to one of the at least two TCI states indicated by the network-side device; or

[0071] the beam corresponding to the at least two TCI states indicated by the network-side device.

[0072] The network-side device indicating at least two TCI states can be that the network-side device indicates one TCI code point corresponding to two TCI states, or the network-side device indicating at least two TCI states can include that the PDCCH indicated by the CORESET pool index (CORESETPoolindex) #0 corresponds to TCI state #1, and the PDCCH indicated by the CORESETPoolindex #1 corresponds to TCI state #2.

[0073] The case that the network-side device indicates at least two TCI states can also be understood as the case that the terminal is configured with multi-TRP (mTRP) or activated mTRP or uses mTRP.

[0074] The beam corresponding to one of the at least two TCI states indicated by the network-side device can be the beam corresponding to the selected one of the at least two TCI states indicated by the network-side device as the first beam, for example, the beam corresponding to one of the at least two TCI states indicated by the network-side device includes one of the following:

[0075] the beam corresponding to the TCI state associated with the first CORESET of the serving cell in the at least two TCI states indicated by the network-side device; or

[0076] the beam corresponding to the first indicated TCI state in the at least two TCI states indicated by the network-side device; or

[0077] the beam with the best beam quality or any one of the beams in the beams corresponding to the at least two TCI states indicated by the network-side device; or

[0078] the beam corresponding to the TCI state associated with the serving cell in the at least two TCI states indicated by the network-side device.

[0079] The first TCI state can be a TCI state indicated first or ranked first among the at least two TCI states indicated by the network device, for example: one DCI indicates one codepoint, the codepoint corresponds to one of the M TCI codepoints activated by the MAC CE, one TCI codepoint corresponds to two TCI states {TCI state#1, TCI state#2}, wherein TCI state#1 is for TRP#1, and TCI state#2 is for TRP#2; and the first TCI state is TCI state#1.

[0080] The beam corresponding to the TCI state associated with the serving cell among the at least two TCI states indicated by the network device can be the beam corresponding to the TCI state associated with the serving cell if only one of the indicated TCI states is associated with the serving cell, and the other indicated TCI states are associated with neighboring cells.

[0081] In this embodiment, a more suitable TCI state can be selected from the at least two TCI states to improve the reliability of measurement.

[0082] In some embodiments, in the case that the first beam of the serving cell includes the beam corresponding to the TCI state indicated by the network device, and the beam corresponding to the TCI state indicated by the network device includes the beams corresponding to the at least two TCI states indicated by the network device, the measurement result of the first beam of the serving cell includes one of the following:

[0083] a linear average of the measurement results of the beams corresponding to the at least two TCI states; or

[0084] a weighted average of the measurement results of the beams corresponding to the at least two TCI states; or

[0085] the measurement results of the beams corresponding to the at least two TCI states.

[0086] The measurement result of the beam is a measurement result measured by the terminal before determining whether the trigger event is met or before performing step 201, for example: the terminal measures when receiving the measurement configuration (the measurement configuration is not the measurement configuration for triggering layer 1 measurement reporting and LTM) sent by the network device, and when the measurement result meets the trigger event, triggers layer 1 measurement reporting or performs conditional LTM.

[0087] In this embodiment, the measurement results of the beams corresponding to the multiple TCIs are evaluated for the measurement event, i.e., the quality of the two or more beams is considered simultaneously to form the quality of the first beam of the serving cell, and the measurement event is evaluated, thereby improving the reliability of the measurement.

[0088] The linear average of the measurement results of the beams corresponding to the at least two TCI states refers to linearly averaging the measurement results of the beams corresponding to the two or more indicated TCI states, and taking the obtained measurement results as the final measurement results of the first beam.

[0089] The weighted average of the measurement results of the beams corresponding to the at least two TCI states refers to weightedly averaging the measurement results of the beams corresponding to the two or more indicated TCI states, and the weight values corresponding to the beams can be agreed upon by protocols or configured by the network side device, for example, the weight of the first indicated TCI state is N, and the weight of the second indicated TCI state is M.

[0090] The measurement results of the first beam of the serving cell including the measurement results of the beams corresponding to the at least two TCI states refers to evaluating whether the triggering event is met based on the measurement results of the beams corresponding to the two or more indicated TCI states.

[0091] In the case where the measurement results of the first beam of the serving cell include the measurement results of the beams corresponding to the at least two TCI states, the measurement results of the target beam meet the triggering event include one of the following:

[0092] The measurement results of the beams corresponding to the at least two TCI states all meet the triggering event.

[0093] At least one of the measurement results of the beams corresponding to the at least two TCI states meets the triggering event.

[0094] The measurement result of the beam with better quality among the measurement results of the beams corresponding to the at least two TCI states meets the triggering event.

[0095] That is, when the measurement results of the beams corresponding to the two or more indicated TCI states all meet the event evaluation condition or at least one meets the evaluation condition, it is considered that the event meets the evaluation condition.

[0096] As an optional embodiment, the second beam of the neighbor cell is associated with the first beam of the serving cell.

[0097] The association of the second beam of the neighbor cell with the first beam of the serving cell can be that the first cell of the serving cell determines the second cell of the neighbor cell, so that the second beam of the neighbor cell and the first beam of the serving cell are matched, so that for a trigger event of the end of measurement including the second beam of the neighbor cell and the first beam of the serving cell, the evaluation of the trigger event can be more reliable.

[0098] In an optional implementation, the second beam of the neighbor cell satisfies at least one of the following:

[0099] The TRP to which the second beam of the neighbor cell belongs is matched with the TRP to which the first beam of the serving cell belongs;

[0100] The number of beams of the second beam of the neighbor cell is the same as the number of beams of the first beam of the serving cell.

[0101] In the embodiments of the present application, the TRP can also be characterized by any of the following:

[0102] A CORESET pool index (CORESETPoolindex);

[0103] A reference signal (Reference Signal, RS) set;

[0104] A channel group.

[0105] In the case where the TRP to which the second beam of the neighbor cell belongs is matched with the TRP to which the first beam of the serving cell belongs, the second beam of the neighbor cell can be any beam of the neighbor cell whose TRP is matched with the TRP to which the first beam of the serving cell belongs, and specifically can be any beam configured with measurement resources.

[0106] The TRP to which the second beam of the neighbor cell belongs can be matched with the TRP to which the first beam of the serving cell belongs, that is, the identification information corresponding to the TRP to which the second beam of the neighbor cell belongs is the same as the identification information corresponding to the TRP to which the first beam of the serving cell belongs, such as the same CORESETPoolindex or RS set identifier or channel group identifier.

[0107] The number of beams of the second beam of the neighbor cell can be the same as the number of beams of the first beam of the serving cell, that is, in the case where the first beam of the serving cell is a plurality of beams, the first cell of the neighbor cell is also a plurality of beams, and the number is the same.

[0108] In the above embodiments, since the second beam of the neighbor cell matches the TRP to which the first beam of the serving cell belongs, or the number of beams is the same, the second beam of the neighbor cell and the first beam of the serving cell can be matched, so that the evaluation of the triggering event including the measurement end of the second beam of the neighbor cell and the first beam of the serving cell can be more reliable.

[0109] As an optional embodiment, in the case where the second beam of the neighbor cell includes at least two beams, the measurement result of the second beam of the neighbor cell includes one of the following:

[0110] a linear average of the measurement results of the at least two beams; or

[0111] a weighted average of the measurement results of the at least two beams; or

[0112] the measurement results of the at least two beams.

[0113] In this embodiment, it can be applied to the case where the first beam of the serving cell includes at least two beams, and the number of beams of the second beam of the neighbor cell is the same as the number of beams of the first beam of the serving cell.

[0114] For example, in the case where the measurement result of the serving cell is linearly averaged by multiple beams, the measurement result of the neighbor cell is also linearly averaged by multiple beams, and then the event is evaluated.

[0115] For another example, in the case where the measurement result of the serving cell is weightedly averaged by multiple beams, the measurement result of the neighbor cell is also weightedly averaged by multiple beams, and then the event is evaluated.

[0116] For another example, in the case where the measurement result of the serving cell uses at least two beams, the measurement result of the neighbor cell also uses multiple beams to compare with the measurement result of the multiple beams of the serving cell respectively, and when all the evaluation conditions are met, it is considered that the event is met.

[0117] In this embodiment, the measurement result of the neighbor cell can be evaluated by multiple beams to improve the reliability of the evaluation of the triggering event.

[0118] In some embodiments, in the case where the measurement result of the second beam of the neighbor cell includes the measurement result of the at least two beams, the measurement result of the target beam satisfying the triggering event includes:

[0119] a comparison result between the measurement result of the beam belonging to the first TRP in the at least two beams and the measurement result of the beam belonging to the second TRP in the first beam of the serving cell satisfies the triggering event;

[0120] The comparison result between the measurement result of the beam of the third TRP to which the at least two beams belong and the measurement result of the beam of the fourth TRP in the first beam of the serving cell satisfies a triggering event.

[0121] In some embodiments, the identification information corresponding to the first TRP and the second TRP can be the same, such as corresponding to the same CORESETPoolindex or RS set identification or channel grouping identification.

[0122] In some embodiments, the identification information corresponding to the third TRP and the fourth TRP can be the same, such as corresponding to the same CORESETPoolindex or RS set identification or channel grouping identification.

[0123] The first TRP and the third TRP can be beams that the terminal can receive simultaneously, and the second TRP and the fourth TRP can be beams that the terminal can receive simultaneously.

[0124] The matching between the TRPs is described in the above embodiments, which will not be repeated here.

[0125] The comparison result between the measurement result of the beam of the first TRP to which the at least two beams belong and the measurement result of the beam of the second TRP in the first beam of the serving cell satisfies a triggering event can be that the comparison result between the measurement result of any beam of the first TRP to which the at least two beams belong and the measurement result of the beam of the second TRP in the first beam of the serving cell satisfies a triggering event.

[0126] The comparison result between the measurement result of the beam of the third TRP to which the at least two beams belong and the measurement result of the beam of the fourth TRP in the first beam of the serving cell satisfies a triggering event can be that the comparison result between the measurement result of any beam of the third TRP to which the at least two beams belong and the measurement result of the beam of the fourth TRP in the first beam of the serving cell satisfies a triggering event.

[0127] In this embodiment, the measurement result corresponding to the matched TRP can be used to evaluate the triggering event, which can improve the reliability of the evaluation.

[0128] As an optional embodiment, the method further comprises:

[0129] The terminal receives layer 1 measurement related configuration information, and the layer 1 measurement related configuration information is used to indicate the TRP to which at least one beam belongs.

[0130] The configuration information is layer 1 measurement related configuration information sent by the network side device to the terminal, for example, when the network side device configures the beam measurement resource, it indicates that beam 1 belongs to TRP1 and beam 2 belongs to TRP2.

[0131] In this embodiment, the layer 1 measurement related configuration information can accurately determine the TRP to which each beam belongs.

[0132] In some embodiments, for the mTRP scenario, the multiple beams of the mTRP can be configured in the following two ways:

[0133] Only beam 1 and beam 2 are configured in one separate LTM CSI resource configuration;

[0134] At least two beam resource configuration lists are included in the LTM CSI resource configuration. The first beam corresponding to list one and the first beam corresponding to list two represent that the network side can transmit simultaneously, and the terminal can also use them to simultaneously receive mTRP.

[0135] When the terminal reports the beam measurement result, for the measurement results of the two beams that can do mTRP, at least one of the following can be performed:

[0136] The measurement results of the two beams are reported simultaneously, and a special reporting signaling can be used to include only the beam measurement results of all mTRPs;

[0141] The determination of the priority of the MAC CE for reporting the layer 1 measurement result can be the determination of the priority of the MAC CE for reporting the layer 1 measurement result in the logical channel prioritization (LCP) process.

[0142] In some embodiments, the priority of the MAC CE can be determined according to the following priority order (the priority is listed from high to low):

[0163] wherein the priority between MAC CEs of the same priority depends on the UE implementation.

[0164] In some embodiments, the MAC CE has the highest priority among the MAC CEs in the logical channel prioritization (LCP) process; or,

[0165] the priority of the MAC CE is equal to the priority of the MAC CE with the cell radio network temporary identifier (C-RNTI) or equal to the priority of the message on the uplink common control channel (UL-CCCH); or,

[0168] The highest priority of the MAC CE can be higher than a priority of a MAC CE of a C-RNTI or a message of a UL-CCCH.

[0170] The priority of the MAC CE between the first priority and the second priority can be lower than the priority of the MAC CE between the first priority and the second priority, but higher than a priority of a MAC CE for BFR or a MAC CE for configured grant confirmation or a MAC CE for multi-entity configured grant confirmation.

[0171] In this embodiment, the priority of the MAC CE for reporting the layer 1 measurement result can be flexibly determined to support flexible reporting of the layer 1 measurement result.

[0172] The terminal determines the priority of the scheduling request (SR) according to a protocol agreement or a network side device configuration.

[0173] As an optional embodiment, the method further comprises:

[0174] The terminal determines that a target physical uplink control channel (PUCCH) resource is a valid resource, wherein the target PUCCH resource includes one of the following:

[0175] A PUCCH resource corresponding to a pending SR of beam failure recovery of a reference signal of the serving cell; or

[0176] A PUCCH resource corresponding to a pending SR of layer 1 measurement result reporting.

[0177] The PUCCH resource corresponding to the pending SR of the beam failure recovery of the reference signal of the serving cell can include at least one of the following:

[0178] PUCCH resource for SCell beam failure recovery for the SR transmission occasion

[0179] PUCCH resource for SCell beam failure recovery for the SR transmission occasion

[0180] The PUCCH resource corresponding to the pending SR for beam failure recovery of the reference signal of the serving cell can be a PUCCH resource that the MAC entity of the terminal considers as a valid resource only for the pending SR for beam failure recovery of the reference signal of the serving cell.

[0181] The PUCCH resource corresponding to the pending SR for L1 measurement result reporting can be a PUCCH resource that the MAC entity of the terminal considers as a valid resource only for the pending SR for L1 measurement result reporting.

[0182] In this embodiment, the dedicated SR can be sent on the PUCCH resource corresponding to the pending SR for beam failure recovery of the reference signal of the serving cell or the PUCCH resource corresponding to the pending SR for L1 measurement result reporting, so that no additional PUCCH resource needs to be added, thereby saving resource overhead.

[0183] In some embodiments, whether the PUCCH resource corresponding to the pending SR for beam failure recovery of the reference signal of the serving cell or the PUCCH resource corresponding to the pending SR for L1 measurement result reporting is valid can be determined based on a measurement event triggering L1 measurement result reporting.

[0184] In some embodiments, if the event triggering L1 measurement result reporting is only related to the beam of the serving cell, the target PUCCH resource is the PUCCH resource corresponding to the pending SR for beam failure recovery of the reference signal of the serving cell.

[0185] In some embodiments, if the event triggering the reporting of the Layer 1 measurement result is only related to the beam of the neighbor cell, the target PUCCH resource is the PUCCH resource corresponding to the pending SR of the reporting of the Layer 1 measurement result.

[0186] For example, when the event triggering the reporting of the Layer 1 measurement result is only related to the beam of the serving cell (such as the LTM event 1 or the event 2), the PUCCH resource corresponding to the pending SR of the beam failure recovery of the reference signal of the serving cell is valid; otherwise, the PUCCH resource corresponding to the pending SR of the reporting of the Layer 1 measurement result is valid.

[0187] Through the above embodiments, a more suitable PUCCH resource can be selected to transmit the above-mentioned dedicated SR, so as to improve the transmission reliability of the dedicated SR.

[0188] In some embodiments, under a first condition, the target PUCCH resource is the PUCCH resource corresponding to the pending SR of the reporting of the Layer 1 measurement result, and the first condition refers to that the triggering event includes one of the following:

[0189] The measurement result of the second beam of the neighbor cell is greater than or equal to the measurement result of the first beam of the serving cell, and the difference between the measurement result of the second beam of the neighbor cell and the measurement result of the first beam of the serving cell is greater than or equal to a first offset value; or

[0190] The measurement result of the second beam of the neighbor cell is greater than or equal to a first threshold, and the difference between the measurement result of the second beam of the neighbor cell and the measurement result of the first beam of the serving cell is greater than or equal to a second offset value; or

[0191] The measurement result of the first beam of the serving cell is greater than or equal to a second threshold, and the measurement result of the second beam of the neighbor cell is greater than or equal to a third threshold.

[0192] The triggering event referred to by the first condition can be the event three, the event four or the event five described in the above embodiments.

[0193] In this embodiment, the PUCCH resource corresponding to the pending SR of the reporting of the Layer 1 measurement result can be determined as a valid resource under the first condition, so as to transmit the dedicated SR on the PUCCH resource, so that the dedicated SR transmitted is matched with the triggering event, and the reporting of the Layer 1 measurement result is more reliable.

[0194] In some embodiments, the terminal determines the target PUCCH resource as a valid resource by:

[0195] Under a second condition, the terminal determines the target PUCCH resource as a valid resource, wherein the second condition includes:

[0196] at least one of a suspended SR for beam failure recovery of a reference signal of a serving cell and a suspended SR for reporting of layer 1 measurement results;

[0197] PUCCH resource conflicts, including at least one of: PUCCH resource conflicts of the at least one PUCCH resource corresponding to a suspended SR for beam failure recovery of a reference signal of a serving cell, and PUCCH resource conflicts of the at least one PUCCH resource corresponding to a suspended SR for reporting of layer 1 measurement results.

[0198] The at least one PUCCH resource is one or more PUCCH resources other than a PUCCH resource corresponding to the suspended SR for beam failure recovery of the reference signal of the serving cell and a PUCCH resource corresponding to the suspended SR for reporting of the layer 1 measurement results.

[0199] In this embodiment, the PUCCH resource corresponding to the suspended SR is determined to be a valid resource under the second condition, so that no additional PUCCH resource needs to be added, thereby saving resource overhead.

[0200] In the embodiments of the present application, the terminal determines a target beam, the target beam including at least one of: a first beam of a serving cell and a second beam of a neighbor cell; and in a case where a measurement result of the target beam satisfies a triggering event, the terminal triggers reporting of layer 1 measurement or performs conditional LTM. In this way, reporting of layer 1 measurement triggered by an event or performing conditional LTM can be implemented, so that the terminal can timely perform reporting of layer 1 measurement or performing LTM, and the terminal switching process can be avoided, thereby improving the communication performance of the terminal.
