Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The solutions of the embodiments of the present application can also be applicable to new communication systems in the future, for example, a sixth generation (6G) communication system, a seventh generation (7G) communication system, and the like.

[0040] This application mainly relates to the communication between terminal devices and network devices.

[0041] The terminal equipment (Terminal Equipment) in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user device. The terminal equipment may 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 in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited to this. In some embodiments of the present application, the terminal equipment may also be a device with a transceiver function, such as a chip system. Among them, the chip system may include a chip and may also include other discrete devices.

[0042] In the embodiments of the present application, a network device may refer to a device that provides wireless communication functionality for a terminal device. The network device may be referred to as an access network device, such as a radio access network (RAN) device or an access network element. The network device may support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device may be a base station (BS) (also referred to as a base station device), the device providing base station functions in the second-generation (2G) network includes a base transceiver station (BTS), the device providing base station functions in the 3G network includes a node B (Node B), the device providing base station functions in the 4G network includes an evolved node B (eNB), and the device providing base station functions in the 5G network includes a next generation node B (gNB) and an evolved node B (ng-eNB), wherein the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both the gNB and the ng-eNB can be connected to the 5G core network. In wireless local area networks (WLAN), the device providing base station functions is an access point (AP). The network devices in the embodiments of the present application also include devices that provide wireless communication functions in future new communication systems. In some embodiments, the network devices may also be devices that provide wireless communication functions for terminals, such as chip systems. For example, chip systems may include chips and other discrete components.

[0043] In some embodiments, the network device may refer to a centralized unit (CU) of a base station, or a distributed unit (DU) of a base station, or a CU control plane (CU-CP) of a base station, or a DU user plane (CU-up) of a base station, etc.

[0044] The network device in the embodiment of the present application may refer to a source base station. Alternatively, the network device may be a master base station.

[0045] The communication method provided in the embodiment of the present application can be applied to a single connection scenario, where a single connection scenario means that only a single base station provides services for a terminal device. Alternatively, the communication method provided in the embodiment of the present application can also be applied to a multi-radio dual connection (Multi Radio Dual Connectivity, referred to as MR-DC) scenario. Specifically, the primary base station and the secondary base station provide services for the terminal device at the same time. The embodiment of the present application does not limit the type of dual connection, and the dual connection can be LTE dual connection, LTE and NR dual connection, NR dual connection, etc. For the dual connection of LTE and NR, it can include EN-DC (E-UTRAN NR Dual Connectivity, that is, the LTE base station serves as the primary base station of the UE and the NR base station serves as the secondary base station of the UE), NE-DC (NR E-UTRAN Dual Connectivity, that is, the NR base station serves as the primary base station of the UE and the LTE base station serves as the secondary base station of the UE), NR-DC (NR NR Dual Connectivity, that is, the primary base station and the secondary base station of the UE are both NR base stations), NGEN-DC (that is, the LTE base station connected to the 5G core network serves as the primary base station of the UE and the NR base station serves as the secondary base station of the UE), etc.

[0046] To reduce cell handover latency, wireless communication systems have introduced a Layer 1 / Layer 2 triggered mobility (LTM) mechanism. In the LTM mechanism, network devices trigger a cell handover process using a medium access control element (MAC CE) based on Layer 1 (L1) measurement results. It should be noted that Layer 1 can also be referred to as the physical layer, Layer 2 can be the MAC layer, and Layer 3 can be the RRC layer. "Layer 1 measurement results" can also be referred to as "physical layer measurement results."

[0047] Specifically, in the LTM handover mechanism, the terminal device periodically reports measurement reports to the network device, or, based on a trigger or instruction from the network device, reports measurement reports to the network device at a specific moment. The measurement reports include Layer 1 measurement results. Furthermore, the network device makes a handover decision based on the measurement reports and sends a handover command to the terminal device via Layer 1 or Layer 2 signaling.

[0048] In the above scheme, since the terminal device periodically reports the measurement report or reports the measurement report based on the instruction of the network device, if the channel environment in which the terminal device is located is poor and a cell switch is required, but the reporting cycle is not met or the network device does not trigger the report in time, the terminal device will not be able to report in time, resulting in the network device being unable to make a switching decision, resulting in untimely switching. In addition, if the channel environment in which the terminal device is located is good and no cell switching is required, the terminal device still needs to report according to the period or report based on the triggering or instruction of the network device. Since the network device usually does not make a switching decision in this case, it will result in a waste of resources.

[0049] In view of this, an embodiment of the present application provides a communication method. In the scheme of the embodiment of the present application, the terminal device sends a measurement report or triggers switching in response to the measurement result meeting the condition, and the measurement result meeting the condition includes that the measurement result of layer 1 meets the first condition. That is to say, in the scheme of the embodiment of the present application, the terminal device independently determines whether the measurement result of layer 1 meets the first condition, and sends a measurement report to the network device when the measurement result of layer 1 meets the first condition, or directly performs switching when the measurement result of layer 1 meets the first condition. Compared with the above-mentioned LTM switching mechanism, the scheme provided by the embodiment of the present application triggers reporting or switching according to the measurement result of layer 1, which is conducive to timely cell switching when the channel environment is poor, and can also avoid invalid reporting when the channel environment is good, which is conducive to saving signaling overhead.

[0050] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] Example 1

[0052] Referring to Figure 1, which is a schematic diagram of signaling interaction in a communication method according to an embodiment of the present application, the communication method shown in Figure 1 may include steps S11 to S13.

[0053] Step S11: The terminal device performs layer 1 measurement.

[0054] Step S12: The terminal device determines whether the measurement result of layer 1 meets the first condition.

[0055] Step S13: The terminal device sends a measurement report to the network device.

[0056] In step S11, the terminal device can measure the beam in the serving cell and / or the alternative cell to obtain the beam measurement result. "Layer 1 measurement" can also be called "beam measurement". The beam measurement result can be reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference and noise ratio (SINR), received signal code power (RSCP), signal-to-noise ratio (SNR), channel quality indicator (CQI), precoding matrix indicator (PMI), etc., but is not limited to these.

[0057] Specifically, the terminal device may measure the serving beam to obtain a beam measurement result of the serving beam. The serving beam may refer to a beam of a serving cell that provides service to the terminal device. For example, the serving beam may be an activated beam within the serving cell, or may be a beam that can be measured within the serving cell.

[0058] Exemplarily, within the same time period, the number of service beams may be 1. For example, the service beam may be a beam within the primary service cell. The number of service beams may also be multiple. In this case, the beam measurement result of the service beam may be the average value of the measurement results of multiple service beams. The multiple service beams may be beams of the same service cell, or the multiple service beams may be beams of multiple service cells. For example, a terminal device accesses a single service cell, and one or more beams of the service cell provide services for the terminal device. For another example, a terminal device accesses multiple service cells, and one or more beams of each service cell provide the terminal device with the services of the service cell.

[0059] The terminal device can measure M beams of the candidate cell and obtain beam measurement results of the M beams. The M beams can be beams measured in the candidate cell, or the M beams can be beams that can be measured in the candidate cell. M is a positive integer greater than or equal to 1. This embodiment does not limit the specific value of M. The values ​​of M corresponding to different candidate cells can be the same or different.

[0060] Specifically, the candidate cell may be a cell configured or indicated by the network device to the terminal device. Specifically, the network device may configure one or more candidate cells for LTM handover for the terminal device. Each candidate cell is applicable to the solution provided in this embodiment.

[0061] It should be noted that the "candidate cell" may also be referred to as a "target cell" or a "neighboring cell", and this embodiment does not limit this.

[0062] From the above, the measurement results of layer 1 may include the beam measurement results of the serving beam and / or the beam measurement results of one or more candidate cells.

[0063] As a possible implementation method, the measurement result of layer 1 can be obtained through filtering. Specifically, after the terminal device completes the layer 1 measurement each time, it can filter the layer 1 measurement values ​​obtained by Y measurements performed within the measurement time window to obtain the measurement result of this measurement. Y is a positive integer greater than 1, and this embodiment does not limit the value of Y. For example, assuming that the time when the terminal device last performed the layer 1 measurement is T1, and the length of the measurement time window is W1, the terminal device can perform time domain filtering on each measurement value within the measurement time window [T1-W1, T1] to obtain the measurement result of this measurement.

[0064] For example, the measurement result for layer 1 can be the average of Y measurement values ​​within the measurement time window. In other words, the measurement result for layer 1 is the average of the measurement values ​​for layer 1 within the measurement time window. Assuming beam 1 is the measured beam and the beam measurement result is RSRP, the RSRP for beam 1 is the average of Y RSRP values ​​obtained from Y measurements of beam 1 within the measurement time window.

[0065] For another example, the measurement result of layer 1 may be a weighted average of the measurement values ​​of Y measurements within the measurement time window. That is, the measurement result of layer 1 is obtained by weighted averaging the measurement values ​​of layer 1 within the measurement time window. Specifically, each measurement value within the measurement time window has a corresponding weight value, and a weighted average is performed based on the Y measurement values ​​within the measurement time window and the weight values ​​corresponding to each measurement value to obtain the measurement result of layer 1. The weight value may be predefined, or the weight value may be configured by the network device. Assuming that beam 1 is the beam being measured and the beam measurement result is RSRP, the RSRP of beam 1 is the weighted average of Y RSRPs obtained by performing Y measurements on beam 1 within the measurement time window.

[0066] Optionally, the above filtering process may be performed at layer 1 of the terminal device. After obtaining the measurement result of layer 1 through filtering process, the measurement result of layer 1 may be uploaded to a higher layer (eg, layer 3) of the terminal device.

[0067] In step S12, the terminal device determines whether the measurement result of layer 1 meets the first condition.

[0068] The first condition may be predefined by a protocol, or the first condition may be configured by a network device. Exemplarily, the network device may send configuration information to the terminal device, and the configuration information may be used to configure at least the first condition. For example, the configuration information may be carried in radio resource control (RRC) reconfiguration signaling. For another example, the network device may configure the first condition when configuring the alternative cell.

[0069] In the solution of this embodiment, the first condition may include any one or more of the following:

[0070] Condition 1: The measurement result of the candidate cell is greater than or equal to the first threshold;

[0071] Condition 2: The measurement result of the candidate cell is greater than or equal to the beam measurement result of the serving beam;

[0072] Condition 3: The beam measurement result of the serving beam is less than or equal to the second threshold;

[0073] Condition 4: The number of first beams among the M beams in the candidate cell is greater than or equal to the third threshold. The first beam herein refers to a beam for which the beam measurement result is greater than or equal to the fourth threshold. It should be noted that Condition 4 may also mean that M first beams can be measured in the candidate cell, and M is greater than or equal to the third threshold.

[0074] The first condition is described below by way of example.

[0075] Example a: The first condition is condition 1. That is, the first condition is: the measurement result of the candidate cell is greater than or equal to the first threshold. This first condition can also be called a first event.

That is, the first condition is: the measurement result of the candidate cell is greater than or equal to the first threshold, and the beam measurement result of the serving beam is less than or equal to the second threshold. This first condition can also be called the sixth event.

[0081] Example g. The first condition is condition 1 plus condition 4. That is, the first condition is: the measurement result of the candidate cell is greater than or equal to the first threshold, and the number of the first beam in the M beams within the candidate cell is greater than or equal to the third threshold. This first condition can also be called the seventh event.

[0082] Example h. The first condition is condition 2 and condition 3. That is, the first condition is: the measurement result of the candidate cell is greater than or equal to the beam measurement result of the serving beam, and the beam measurement result of the serving beam is less than or equal to the second threshold. This first condition can also be called the eighth event.

[0083] Example i. The first condition is condition 2 plus condition 4. That is, the first condition is: the measurement result of the candidate cell is greater than or equal to the beam measurement result of the serving beam, and the number of first beams in the M beams is greater than or equal to the third threshold. The first beam is a beam whose beam measurement result is greater than or equal to the fourth threshold. This first condition can also be referred to as the ninth event.

That is, the first condition is: the beam measurement result of the serving beam is less than or equal to the second threshold, and the number of first beams in the M candidate cell beams is greater than or equal to the third threshold. This first condition can also be called the tenth event.

This first condition can also be referred to as the eleventh event.

This first condition can also be referred to as the fourteenth event.

[0089] It should be noted that this article does not limit the names of the above-mentioned events. In actual applications, the above-mentioned events may also use other names.

[0090] It should also be noted that if the number of serving beams is one, then the "beam measurement result of the serving beam" in Examples a through n above may refer to the beam measurement result of that serving beam. If the number of serving beams is multiple, then the "beam measurement result of the serving beam" in Examples a through n above may refer to the average or weighted average of the beam measurement results of multiple serving beams.

[0091] In a specific implementation, the "measurement results of the candidate cell" in the above examples a to n can be obtained based on the beam measurement results of one or more beams among the M beams of the candidate cell.

[0092] Specifically, the measurement results of the alternative cell may include the following: any one or more of the first measurement results to the fifth measurement results. Among them, the first measurement result refers to: the beam measurement result of the beam with the best beam measurement result among the M beams. The second measurement result refers to: the average value of the beam measurement results of the M beams. The third measurement result refers to: the average value of the beam measurement results of the L beams with the best beam measurement results among the M beams, where L is a positive integer greater than 1.

The fifth measurement result refers to the average value of the beam measurement results of the N beams with the best beam measurement results among the third beam among the M beams, where the third beam refers to the beam whose beam measurement result is greater than or equal to the sixth threshold value, where N is a positive integer greater than 1. If the number of third beams in the M beams is greater than or equal to N, the fifth measurement result can be the average of the beam measurement results of the N beams with the best beam measurement results in the third beams; if the number of third beams in the M beams is less than N, the fifth measurement result can be the average of the beam measurement results of all third beams in the M beams.

[0093] It should be noted that, when the measurement results of the candidate cells refer to different measurement results, the first threshold value may be a threshold value corresponding to the different measurement results.

[0094] Exemplarily, the above-mentioned condition 1 may include any one or more of the following: the first measurement result of the alternative cell is greater than or equal to the eighth threshold value; the second measurement result of the alternative cell is greater than or equal to the ninth threshold value; the third measurement result of the alternative cell is greater than or equal to the tenth threshold value; the fourth measurement result of the alternative cell is greater than or equal to the eleventh threshold value; and the fifth measurement result of the alternative cell is greater than or equal to the twelfth threshold value.

[0095] As another example, the above-mentioned condition 2 may include any one or more of the following: the first measurement result of the alternative cell is greater than or equal to the beam measurement result of the service beam; the second measurement result of the alternative cell is greater than or equal to the beam measurement result of the service beam; the third measurement result of the alternative cell is greater than or equal to the beam measurement result of the service beam; the fourth measurement result of the alternative cell is greater than or equal to the beam measurement result of the service beam; the fifth measurement result of the alternative cell is greater than or equal to the beam measurement result of the service beam.

[0096] Furthermore, in step S13, based at least on the Layer 1 measurement result satisfying the first condition, the terminal device sends a measurement report. The measurement report may be carried in Layer 1 signaling, Layer 2 signaling, or Layer 3 signaling. The measurement report may include at least a portion of the Layer 1 measurement result that satisfies the first condition. For example, the measurement report may include the beam measurement result of the serving beam and the measurement result of the candidate cell that satisfies the first condition. This embodiment does not limit the specific content of the measurement report.

[0097] As a possible implementation, once the terminal device determines in step S12 that the measurement result of layer 1 meets the first condition, the terminal device may execute step S13. If the terminal device determines in step S12 that the measurement result of layer 1 does not meet the first condition, the terminal device does not execute step S13 and continues to perform layer 1 measurement.

[0098] As another possible implementation, the first condition may be an entry condition, and the condition for the terminal device to report the measurement report to the network device (also referred to as a "reporting condition") may further include a persistence condition. When it is determined that both the entry condition (i.e., the first condition) and the persistence condition are met, the terminal device may determine that the reporting condition is met. If the terminal device determines that the reporting condition is met, step S13 is executed; if the reporting condition is not met, step S13 is not executed.

[0099] Specifically, when the entry condition is met, the terminal device further determines whether the persistence condition is met.

[0100] In one example, the persistence condition may be the number of times the entry condition is continuously satisfied. For example, if the terminal device determines that the entry condition is satisfied K times in a row, then the terminal device determines that the persistence condition is satisfied, where K is a positive integer greater than 1. In other words, if the terminal device determines that the measurement results of layer 1 satisfy the first condition K times in a row, then the terminal device sends a measurement report to the network device.

[0101] In another example, the persistence condition may be that the measurement results of layer 1 meet the first condition at least P times within a first time period. Alternatively, the persistence condition may mean that the ratio of the number of times the measurement results of layer 1 meet the first condition within the first time period to the number of times the measurement results of layer 1 are obtained within the first time period reaches a seventh threshold. The first time period may be a recent period. For example, assuming that the time when the measurement result of layer 1 was most recently obtained is T2 and the length of the first time period is W2, the first time period may be [T2-W2, T2]. Assuming that a total of X layer 1 measurement results are obtained within the first time period, if at least P of the X measurement results meet the first condition, the terminal device may determine that the persistence condition is met. X is a positive integer greater than or equal to 1, and P is a positive integer greater than or equal to 1, with X ≥ P. In a specific implementation, the value of P may be defined by the protocol or configured by the network device. Alternatively, the value of P may depend on the seventh threshold defined by the protocol or pre-configured by the network device, and the value of P is the product of X and the seventh threshold. In this example, if the terminal device determines that the measurement results of layer 1 within the first time period meet the first condition at least P times, or the ratio of the number of times the measurement results of layer 1 within the first time period meet the first condition to the number of times the measurement results of layer 1 are obtained within the first time period reaches the seventh threshold value, the terminal device sends a measurement report to the network device.

[0102] As another possible implementation, if the layer 1 measurement result obtained by the terminal device does not meet the first condition, it can be determined that the leave condition is met. If the leave condition is determined to be met, the reporting of the measurement report is not triggered. For example, if the layer 1 measurement result meets the first condition, and the next measurement result does not meet the first condition, it is determined that the leave condition is met, and the measurement report is not reported.

[0103] As another possible implementation, a leaving condition may be predefined, wherein the leaving condition may correspond to the first condition. For example, the leaving condition may include any one or more of the following:

[0104] Condition 5: The measurement result of the candidate cell is less than the thirteenth threshold;

[0105] Condition 6: The measurement result of the candidate cell is smaller than the beam measurement result of the serving beam;

[0106] Condition 7: The beam measurement result of the serving beam is greater than the fourteenth threshold;

[0107] Condition 8: The number of first beams in the candidate cell is less than the fifteenth threshold.

[0108] Once the terminal device determines that the measurement result of layer 1 meets the leaving condition, the reporting of the measurement report is not triggered. For example, after the measurement result of layer 1 meets the first condition, the next measurement result meets the leaving condition, and the measurement report is not reported. It should be noted that the values ​​of each threshold value are not limited in this document. The values ​​of each threshold value can be defined by the protocol or can be configured by the network device. For example, the configuration information above may include the threshold value corresponding to the first condition, and the network device can implement the configuration of the first condition by configuring the threshold value.

[0109] Furthermore, after the terminal device sends a measurement report to the network device, the network device makes a handover decision based on the measurement report. Furthermore, the network device may send a handover command to the terminal device. The cell handover command may be carried in layer 1 signaling or layer 2 signaling.

[0110] Furthermore, after receiving the cell switching command, the terminal device performs cell switching and switches to the target cell indicated by the cell switching command.

[0111] From the above, in the solution provided by this embodiment, the terminal device autonomously triggers reporting based on the measurement results of layer 1, and can report measurement reports when the channel environment is poor, which is conducive to timely cell switching. It can also avoid invalid reporting when the channel environment is good, which is conducive to saving signaling overhead.

[0113] Example 2

[0114] Referring to Figure 2, Figure 2 is a schematic flow chart of another communication method according to an embodiment of the present application. The solution shown in Figure 2 can be applied to a terminal device. For example, the solution shown in Figure 2 can be executed by the terminal device, or can be executed by a chip or chip module with communication functions in the terminal device. As shown in Figure 2, the communication method shown in Figure 2 can include steps S21 to S22.

[0115] Step S21: evaluating whether the measurement result satisfies a condition, wherein the measurement result satisfying the condition includes that the measurement result of layer 1 satisfies a first condition;

[0116] Step S22: In response to the measurement result meeting the condition, triggering the handover.

[0117] In step S21, the terminal device may perform layer 1 measurement, obtain a layer 1 measurement result, and then determine whether the layer 1 measurement result meets a first condition.

[0118] It should be noted that, regarding the specific contents of the terminal device performing layer 1 measurement, the layer 1 measurement results and the first condition, please refer to the relevant description of Example 1 and will not be repeated here.

[0119] Furthermore, if the terminal device determines that the measurement results of Layer 1 meet the first condition, the terminal device may trigger a cell handover. In step S22, the terminal device switches from the current serving cell to an alternative cell that meets the first condition. If the measurement results of each alternative cell do not meet the first condition, the terminal device may continue to maintain the RRC connection with the source serving cell.

[0120] As a variation, the first condition may refer to an entry condition, and the condition for the terminal device to trigger switching (also referred to as a "switching condition") may also include a persistence condition.

[0121] In one example, the persistence condition can be the number of times the entry condition is continuously satisfied. For example, if the terminal device determines that the entry condition is satisfied K times in a row, then the terminal device determines that the persistence condition is satisfied, where K is a positive integer greater than 1. In other words, if the terminal device determines that the measurement results of layer 1 satisfy the first condition K times in a row, then the terminal device triggers a handover.

[0122] In another example, the persistence condition may be that the measurement results of layer 1 satisfy the first condition at least P times within the first time period, or the persistence condition may mean that the ratio of the number of times the measurement results of layer 1 satisfy the first condition within the first time period to the number of times the measurement results of layer 1 are obtained within the first time period reaches a seventh threshold. That is, if the terminal device determines that the measurement results of layer 1 satisfy the first condition at least P times within the first time period, or the ratio of the number of times the measurement results of layer 1 satisfy the first condition within the first time period to the number of times the measurement results of layer 1 are obtained within the first time period reaches the seventh threshold, the terminal device triggers handover.

[0123] As another variation, if the terminal device determines that the measurement result of layer 1 meets the leaving condition, handover is not triggered. For example, if the measurement result of layer 1 meets the first condition, and the next measurement result meets the leaving condition, handover is not triggered. For details on whether the measurement result of layer 1 meets the leaving condition, refer to the relevant description of Example 1 and are not repeated here.

[0124] In addition, the measurement result meeting the condition further includes: the measurement result of layer 3 meeting the second condition.

[0125] In practice, network equipment configures candidate cells for LTM, but terminal devices typically also perform Layer 3 measurements. Therefore, the terminal device can also use Layer 3 measurement results to determine whether to trigger a handover. Layer 3 measurement results are obtained by performing Layer 3 filtering on Layer 1 measurement results and can be used to characterize cell measurement results.

[0126] Specifically, in step S21, the terminal device evaluates whether the measurement results of layer 1 meet the first condition and evaluates whether the measurement results of layer 3 meet the second condition. It should be noted that this document does not limit the specific content of the second condition and the specific method for evaluating whether the measurement results of layer 3 meet the second condition. The second condition may include one or more existing layer 3 events (A3 event, A4 event, A5 event), and the method for evaluating whether the measurement results of layer 3 meet the second condition may also be an existing method.

[0127] Furthermore, if the measurement result of layer 1 meets the first condition and the measurement result of layer 3 meets the second condition, the terminal device determines that the switching condition is met and triggers the switching. Specifically, if the measurement result of a candidate cell meets both the first condition and the second condition, the candidate cell can be used as the target cell, and the terminal device switches from the source cell to the target cell.

[0128] Unlike Example 1, in Example 2, the terminal device autonomously triggers cell handover based on Layer 1 measurement results, eliminating the need for the network device to send a handover command via Layer 1 or Layer 2 signaling. This not only reduces signaling overhead but also facilitates timely handover by the terminal device. Furthermore, combining Layer 3 measurement results to determine whether to perform LTM handover helps avoid the ping-pong effect and ensures handover robustness.

[0130] Example 3

[0131] Referring to Figure 3, Figure 3 is a schematic flow chart of another communication method according to an embodiment of the present application. The solution shown in Figure 3 can be applied to a terminal device. For example, the solution shown in Figure 3 can be executed by the terminal device, or can be executed by a chip or chip module with communication functions in the terminal device. As shown in Figure 3, the communication method shown in Figure 3 can include step S31.

[0132] Step S31: In response to the measurement result meeting the condition, the terminal device sends a measurement report to the network device or triggers a handover, and the measurement result meeting the condition includes: the measurement result of layer 1 meets the first condition.

[0133] Optionally, the measurement result meeting the condition may further include: the measurement result of layer 3 meeting a second condition.

[0134] In the solution provided by this embodiment, the terminal device side independently decides whether to report a measurement report or trigger a cell handover based on the measurement results of layer 1, which is not only beneficial to reducing signaling overhead, but also conducive to timely cell handover.

[0135] For more details about this embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.
