Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202210945163.1, entitled "Communication Method and Communication Apparatus," filed with the State Intellectual Property Office of China on August 8, 2022, which is incorporated herein by reference in its entirety.

[0002] This application relates to the field of communication technology, and in particular to communication methods and devices. [Background technology]

[0003] The network device may provide the terminal device with measurement configuration information related to delay measurement, so that the terminal device may perform a delay measurement procedure, such as performing a delay measurement and reporting a measurement result of the delay measurement, based on the measurement configuration information. The measurement configuration information may include information such as a measurement target.

[0004] However, if a network device initiates a measurement object change / removal procedure during the process of the terminal device performing delay measurement, the delay measurement procedure of the terminal device may be affected. For example, reporting of delay measurement results by the terminal device may be affected. The delay measurement here may be a packet data convergence protocol (PDCP) uplink data packet average delay measurement or a PDCP data packet excess delay measurement.

[0005] Therefore, in order to improve the service performance of the terminal device, how to reduce the impact of the measurement object change / removal procedure on the delay measurement procedure of the terminal device is a problem that needs to be considered now. Summary of the Invention

[0006] This application provides a communication method and a communication device for reducing the impact of a measurement object change / removal procedure on a delay measurement procedure of a terminal device.

[0007] According to a first aspect, a communication method is provided. The method can be performed by a terminal device, or can be performed by a chip or circuit configured in the terminal device. This is not a limitation in this application. For convenience, the following description will use an example in which the terminal device performs the method.

[0008] The method includes a terminal device receiving first measurement configuration information, the first measurement configuration information indicating to modify a first measurement object, the first measurement object being associated with a first measurement identifier, and performing a first operation when the first measurement identifier is not associated with a delay measurement, or performing a second operation when the first measurement identifier is associated with a delay measurement.

[0009] The first operation includes one or more of the following operations: the terminal device deleting a reporting record corresponding to the first measurement identifier, the terminal device stopping a timer corresponding to the first measurement identifier, or the terminal device resetting information associated with the first measurement identifier; the second operation includes one or more of the following operations: the terminal device retaining a reporting record corresponding to the first measurement identifier, the terminal device maintaining timing of a timer, or the terminal device retaining information associated with the first measurement identifier; and the delay measurement includes a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement.

[0010] In the above solution, in the first measurement object change procedure, the terminal device can determine the operation to be performed based on whether the first measurement identifier is associated with a delay measurement. Specifically, only when the first measurement identifier is not associated with a delay measurement, the terminal device performs the first operation, i.e., resets (or deletes) the information associated with the first measurement identifier and used for the measurement (or used to report the measurement result) (i.e., the reporting record and timer corresponding to the first measurement identifier and the information associated with the first measurement identifier), thereby reducing the impact of the first measurement object change procedure on the delay measurement. In other words, in other cases, i.e., when the first measurement identifier is associated with a delay measurement, the terminal device performs the second operation, i.e., does not reset (or delete) the information associated with the first measurement identifier and used for the measurement (or used to report the measurement result) (i.e., the reporting record and timer corresponding to the first measurement identifier and the information associated with the first measurement identifier). Therefore, the terminal device can continue to report the measurement result of the delay measurement based on such information, thereby improving delay measurement efficiency, saving resources, and improving the service performance of the terminal device.

[0011] In one possible approach, when the first measurement identifier is associated with a delay measurement, the method further includes the terminal device reporting to the network device a measurement result of the delay measurement corresponding to the first measurement identifier based on one or more of a reporting record corresponding to the first measurement identifier, a timer corresponding to the first measurement identifier, or information associated with the first measurement identifier.

[0012] In the above solution, when a first measurement identifier is associated with a delay measurement, the terminal device does not reset (or delete) information associated with the first measurement identifier that is used for the delay measurement (or used to report the measurement result) (i.e., the reporting record and timer corresponding to the first measurement identifier and the information associated with the first measurement identifier). Thus, the terminal device can report the measurement result of the delay measurement associated with the first measurement identifier based on such information, and does not need to regenerate the above information, thereby improving delay measurement efficiency, saving resources, and improving the service performance of the terminal device.

[0013] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0014] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0015] Therefore, based on the above solution, the terminal device can determine whether the first measurement identifier is associated with a delay measurement based on whether the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement, and thereby determine an action to be performed based on whether the first measurement identifier is associated with a delay measurement, thereby reducing the impact of the first measurement target change procedure on the delay measurement.

[0016] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the terminal device transmitting first capability information, wherein the first capability information indicates that in a procedure for changing the second measurement object associated with the delay measurement, the terminal device supports one or more of: supporting keeping a reporting record corresponding to the second measurement identifier, supporting keeping time of a timer corresponding to the second measurement identifier, or supporting keeping information associated with the second measurement identifier, and the second measurement identifier is associated with the second measurement object, and the second measurement identifier is associated with the delay measurement.

[0017] According to the above solution, a terminal device may report first capability information to a network device. Because the first measurement object is one of the second measurement objects, the network device may determine, based on the first capability information, that the terminal device supports performing a second operation when the first measurement identifier is associated with a delay measurement. Therefore, the network device may determine, based on the first capability information, that it can initiate a procedure to change the first measurement object. Since the terminal device supports performing the second operation when the first measurement identifier is associated with a delay measurement, in this case, even if the network device initiates the procedure to change the first measurement object before the delay measurement ends, the terminal device may continue to report the measurement result of the delay measurement using information associated with the first measurement identifier (e.g., a reporting record and a timer corresponding to the first measurement identifier, and information associated with the first measurement identifier), thereby reducing the impact of the procedure to change the first measurement object on the delay measurement.

[0018] According to a second aspect, a communication method is provided. The method can be performed by a terminal device, or can be performed by a chip or circuit configured in the terminal device. This is not a limitation in this application. For convenience, the following description will use an example in which the terminal device performs the method.

[0019] The method includes a terminal device obtaining a first measurement result of a first cell and a second measurement result of a second cell, the second cell being a serving cell of the terminal device, the second cell and the first cell being different cells, the first cell being associated with a first measurement object, and the second cell being associated with a second measurement object, and the terminal device evaluating whether the first measurement result and the second measurement result satisfy a reporting criterion.

[0020] The above solution can avoid resource waste caused by evaluating and reporting measurements of the same cell to a network device, and can avoid possible inappropriate handovers, for example, when a terminal device initiates a cell handover procedure and is handed over from its current serving cell to the cell again.

[0021] In one possible approach, the method further includes the terminal device reporting a measurement report when the measurement results of the first cell and the measurement results of the second cell meet a reporting criterion, the measurement report including the first measurement result and the second measurement result.

[0022] In one possible approach, the reporting criteria is associated with the first measurand.

[0023] In one possible approach, the first measurement result includes a signal quality of a first cell, the second measurement result includes a signal quality of a second cell, and the reporting criteria include one or more of: a difference between the signal quality of the first cell and the signal quality of the second cell being greater than a first threshold, or the signal quality of the first cell being greater than a second threshold and the signal quality of the second cell being less than a third threshold.

[0024] In other words, the reporting criteria may correspond to event A3 and / or event A5.

[0025] According to a third aspect, a communication method is provided. The method can be performed by a terminal device, or can be performed by a chip or circuit configured in the terminal device. This is not a limitation in this application. For convenience, the following description will use an example in which the terminal device performs the method.

[0026] The method includes a terminal device receiving second measurement configuration information, the second measurement configuration information indicating removal of a first measurement object, the first measurement object being associated with a first measurement identifier. The terminal device removes the first measurement object. The terminal device removes the first measurement identifier when the first measurement identifier is not associated with a delay measurement, or the terminal device retains the first measurement identifier when the first measurement identifier is associated with a delay measurement. The delay measurements include Packet Data Convergence Protocol data packet average delay measurements and / or Packet Data Convergence Protocol excess data packet delay measurements.

[0027] According to the above solution, in the procedure for removing the first measurement object, the terminal device can determine an action to be performed based on whether the first measurement identifier is associated with a delay measurement. Specifically, the terminal device removes the first measurement identifier only if the first measurement identifier is not associated with a delay measurement, and the terminal device keeps the first measurement identifier if the first measurement identifier is associated with a delay measurement.

[0028] If the terminal device removes the first measurement identifier in the first measurement object removal procedure and the first measurement identifier is associated with a delay measurement, the terminal device cannot report the measurement result of the delay measurement corresponding to the first measurement identifier, which may affect the service of the terminal device. However, in the above solution, when the first measurement identifier is associated with the delay measurement, the terminal device does not remove the first measurement identifier. Therefore, the terminal device can report the measurement result of the delay measurement using the first measurement identifier, thereby avoiding a case where the first measurement identifier is deleted due to the measurement object removal procedure and therefore the terminal device cannot report the delay measurement result.

[0029] In one possible approach, when the first measurement identifier is associated with a delay measurement, the method further includes the terminal device reporting a measurement result of the delay measurement associated with the first measurement identifier.

[0030] In the above solution, the terminal device can retain the first measurement identifier associated with the delay measurement in the removal procedure of the first measurement object, so that the terminal device can still report the measurement result of the delay measurement by using the first measurement identifier in the removal procedure of the first measurement object, which avoids the case where the measurement result of the delay measurement is not reported due to the removal procedure of the first measurement object, thereby improving the service performance of the terminal device.

[0031] In one possible approach, when the first measurement identifier is associated with a delay measurement, after the terminal device reports a measurement result of the delay measurement associated with the first measurement identifier, the method further includes the terminal device removing the first measurement identifier.

[0032] Based on the above solution, after reporting the measurement result of the delay measurement, the terminal device can delete the first measurement identifier to reduce the resource occupation caused by the first measurement identifier.

[0033] In one possible approach, the method further includes receiving, by the terminal device, third measurement configuration information, the third measurement configuration information indicating removing the first measurement identifier.

[0034] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0035] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0036] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the terminal device transmitting second capability information, the second capability information indicating that the terminal device supports retaining a second measurement identifier associated with the second measurement object in a removal procedure of the second measurement object associated with the delay measurement, and the second measurement identifier is associated with the delay measurement.

[0037] According to the above solution, the terminal device may report second capability information to the network device. Because the first measurement object is one of the second measurement objects, the network device may determine, based on the second capability information, that the terminal device supports retaining the first measurement identifier when the first measurement identifier is associated with the delay measurement. Therefore, the network device may determine, based on the second capability information, that it can initiate a removal procedure for the first measurement object. Because the terminal device supports retaining the first measurement identifier when the first measurement identifier is associated with the delay measurement, in this case, even if the network device initiates the removal procedure for the first measurement object before the delay measurement ends, the terminal device can still report the measurement result of the delay measurement using the first measurement identifier, thereby reducing the impact of the removal procedure for the first measurement object on the delay measurement. In other words, if the network device determines that the terminal device does not support retaining the first measurement identifier associated with the delay measurement in the removal procedure for the first measurement object, the network device may not initiate the removal procedure for the first measurement object (e.g., not initiate it before the delay measurement is completed), thereby avoiding a case where the removal procedure for the first measurement object causes the delay measurement procedure to fail.

[0038] According to a fourth aspect, a communication method is provided. The method can be performed by a terminal device, or can be performed by a chip or circuit configured in the terminal device. This is not a limitation in this application. For convenience, the following description will use an example in which the terminal device performs the method.

[0039] The method includes a terminal device receiving second measurement configuration information, the second measurement configuration information indicating removal of a first measurement object. The terminal device removes the first measurement object and a first measurement identifier associated with the first measurement object, the first measurement identifier being associated with a delay measurement. The terminal device reports a measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier, the first identifier being different from the first measurement identifier, and the delay measurement includes a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement.

[0040] According to the above solution, when a first measurement identifier associated with a delay measurement is removed in a first measurement object removal procedure, the terminal device reports a measurement result of the delay measurement corresponding to the first measurement identifier by using a first identifier different from the first measurement identifier. In other words, even if the first measurement identifier is removed, the terminal device can still report the measurement result of the delay measurement. This avoids the impact of the first measurement object removal procedure on the delay measurement procedure of the terminal device, thereby improving the service performance of the terminal device.

[0041] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0042] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0043] In one possible approach, the terminal device reporting a measurement result of a delay measurement corresponding to the first measurement identifier by using the first identifier includes the terminal device reporting the measurement result based on a reporting configuration corresponding to the first measurement identifier, or the terminal device reporting the measurement result based on a pre-configured reporting configuration.

[0044] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the terminal device transmitting third capability information, the third capability information indicating that the terminal device supports reporting measurement results of the delay measurement using the first identifier in a deletion procedure of the second measurement object associated with the delay measurement.

[0045] Based on the above solution, the terminal device can report third capability information to the network device. Because the first measurement object is one of the second measurement objects, the network device can determine, based on the third capability information, that when the first measurement identifier is associated with a delay measurement, the terminal device supports reporting a measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier in a removal procedure for the first measurement object. Therefore, in this case, even if the network device initiates a removal procedure for the first measurement object before the delay measurement ends and the removal procedure causes the terminal device to remove the first measurement identifier associated with the delay measurement, the terminal device can still report the measurement result of the delay measurement using the first identifier. In other words, the removal procedure for the first measurement object initiated by the network device for the terminal device does not significantly affect the delay measurement of the terminal device. Therefore, the network device can determine, based on the second capability information, that it can initiate a removal procedure for the first measurement object. In other words, when a first measurement identifier is associated with a delay measurement, if the network device determines that the terminal device does not support reporting the measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier in the removal procedure of the first measurement object, the network device may not start the removal procedure of the first measurement object before the delay measurement is completed, thereby avoiding a failure of the delay measurement procedure caused by the removal procedure of the first measurement object.

[0046] According to a fifth aspect, a communication method is provided. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, the following description will use an example in which the network device performs the method.

[0047] The method includes: a network device transmitting first measurement configuration information, the first measurement configuration information indicating changing a first measurement target, the first measurement target being associated with a first measurement identifier; the network device receiving a measurement result from a terminal device when the first measurement identifier is not associated with a delay measurement, the measurement result being reported by the terminal device based on a first operation; or the network device receiving a measurement result from the terminal device when the first measurement identifier is associated with a delay measurement, the measurement result being reported by the terminal device based on a second operation. The first operation includes one or more of the following operations: the terminal device deleting a reporting record corresponding to the first measurement identifier, the terminal device stopping a timer corresponding to the first measurement identifier, or the terminal device resetting information associated with the first measurement identifier; the second operation includes one or more of the following operations: the terminal device retaining a reporting record corresponding to the first measurement identifier, the terminal device maintaining timing of a timer, or the terminal device retaining information associated with the first measurement identifier; and the delay measurement includes a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement.

[0048] Based on the above solution, in the first measurement target change procedure, the network device receives the measurement result reported by the terminal device by using different operations depending on whether the first measurement identifier is associated with the delay measurement. If the first measurement identifier is associated with the delay measurement, the measurement result received by the network device is reported when the terminal device performs the second operation (i.e., does not reset (or does not delete) the information associated with the first measurement identifier that is used for the measurement (or used for reporting the measurement result) (i.e., the reporting record and timer corresponding to the first measurement identifier and the information associated with the first measurement identifier). In other words, when the first measurement identifier is associated with the delay measurement, the terminal device can continue to report the measurement result of the delay measurement based on the above information, and does not need to regenerate the above information, thereby improving delay measurement efficiency, saving resources, and improving the service performance of the terminal device.

[0049] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0050] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the network device receiving first capability information, wherein the first capability information indicates that in a procedure for changing the second measurement object associated with the delay measurement, the network device supports one or more of: supporting maintaining a reporting record corresponding to the second measurement identifier; supporting keeping time of a timer corresponding to the second measurement identifier; or supporting maintaining information associated with the second measurement identifier, wherein the second measurement identifier is associated with the second measurement object, and the second measurement identifier is associated with the delay measurement.

[0051] According to the above solution, a network device receives first capability information from a terminal device. Because the first measurement object is one of the second measurement objects, the network device can determine, based on the first capability information, that the terminal device supports performing a second operation when the first measurement identifier is associated with a delay measurement. Therefore, the network device can determine, based on the first capability information, that it can initiate a procedure to change the first measurement object. Since the terminal device supports performing the second operation when the first measurement identifier is associated with a delay measurement, in this case, even if the network device initiates the procedure to change the first measurement object before the delay measurement ends, the terminal device can continue to report the measurement result of the delay measurement using information associated with the first measurement identifier (e.g., a reporting record and a timer corresponding to the first measurement identifier, and information associated with the first measurement identifier), thereby reducing the impact of the procedure to change the first measurement object on the delay measurement.

[0052] According to a sixth aspect, a communication method is provided. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, the following description uses an example in which the network device performs the method.

[0053] The method includes the network device transmitting second measurement configuration information, the second measurement configuration information indicating removing a first measurement object, the first measurement object being associated with a first measurement identifier. The network device removes the first measurement identifier when the first measurement identifier is not associated with a delay measurement, or the network device retains the first measurement identifier when the first measurement identifier is associated with a delay measurement. The delay measurements include Packet Data Convergence Protocol data packet average delay measurements and / or Packet Data Convergence Protocol excess data packet delay measurements.

[0054] Based on the above solution, in the procedure for removing the first measurement object, the network device can determine the action to be taken based on whether the first measurement identifier is associated with the delay measurement. network The device removes the first measurement identifier only if the first measurement identifier is not associated with a delay measurement, and the network device retains the first measurement identifier if the first measurement identifier is associated with a delay measurement, to avoid a case where the first measurement identifier is deleted due to the measurement object removal procedure and therefore the measurement result of the delay measurement cannot be identified (or obtained).

[0055] In one possible approach, when the first measurement identifier is associated with the delay measurement, the method further includes the network device receiving a measurement result of the delay measurement from the terminal device, the measurement result being associated with the first measurement identifier.

[0056] Based on the foregoing solution, when a first measurement identifier is associated with a delay measurement, the network device can obtain the measurement result of the delay measurement by using the first measurement identifier.

[0057] In one possible approach, when the first measurement identifier is associated with the delay measurement, after the network device receives a measurement result corresponding to the delay measurement from the terminal device, the method further includes the network device removing the first measurement identifier.

[0058] Based on the above solution, the network device can remove the first measurement identifier after receiving the measurement result of the delay measurement from the terminal device, to reduce resource occupation.

[0059] In one possible approach, after the network device receives a measurement result corresponding to the delay measurement from the terminal device, the method further includes the network device sending third measurement configuration information, wherein the third measurement configuration information indicates removing the first measurement identifier.

[0060] Based on the above solution, after the network device receives the measurement result of the delay measurement from the terminal device, the network device can instruct the terminal device to remove the first measurement identifier to reduce the resource occupation of the terminal device.

[0061] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0062] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0063] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the network device receiving second capability information, the second capability information indicating that the terminal device supports retaining a second measurement identifier associated with the second measurement object in a removal procedure of the second measurement object associated with the delay measurement, the second measurement identifier being associated with the delay measurement.

[0064] According to the above solution, when the network device receives the second capability information, since the first measurement object is one of the second measurement objects, the network device can determine based on the second capability information that the terminal device supports retaining the first measurement identifier when the first measurement identifier is associated with the delay measurement. Therefore, the network device can determine based on the second capability information that it can initiate a removal procedure for the first measurement object.

[0065] According to a seventh aspect, there is provided a communication method. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, hereinafter, network An example in which a device executes the method is used for explanation.

[0066] The method includes the network device transmitting second measurement configuration information, the second measurement configuration information indicating removal of a first measurement object, the first measurement object being associated with a first measurement identifier, and when the first measurement identifier is associated with a delay measurement, the network device receiving a measurement result of the delay measurement associated with the first measurement identifier, the delay measurement including a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement.

[0067] According to the above solution, even in the removal procedure of the first measurement object, the network device can still receive the measurement result (i.e., the delay measurement result) corresponding to the first measurement object associated with the delay measurement, which avoids the case where the delay measurement result cannot be reported due to the removal procedure of the first measurement object, thereby improving the success rate of the delay measurement and enhancing the service performance of the terminal device.

[0068] In one possible approach, the method further includes the network device transmitting third measurement configuration information, the third measurement configuration information indicating removing the first measurement identifier.

[0069] Based on the above solution, after the network device receives the delay measurement result associated with the first measurement identifier, the network device can use third measurement configuration information to instruct the terminal device to remove the first measurement identifier, thereby reducing the resource occupation caused by the first measurement identifier.

[0070] In one possible approach, the first measurement identifier is not associated with a delay measurement, and the reporting configuration associated with the first measurement identifier does not include configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0071] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the network device receiving second capability information, the second capability information indicating that the terminal device supports retaining a second measurement identifier associated with the second measurement object in a removal procedure of the second measurement object associated with the delay measurement, the second measurement identifier being associated with the delay measurement.

[0072] According to the above solution, the network device receives second capability information from the terminal device. Because the first measurement object is one of the second measurement objects, the network device can determine, based on the second capability information, that the terminal device supports retaining the first measurement identifier in the removal procedure for the first measurement object when the first measurement identifier is associated with the delay measurement. Therefore, the network device can determine, based on the second capability information, that it can initiate the removal procedure for the first measurement object. Since the terminal device supports retaining the first measurement identifier when the first measurement identifier is associated with the delay measurement, in this case, even if the network device initiates the removal procedure for the first measurement object before the delay measurement ends, the terminal device can still report the measurement result of the delay measurement using the first measurement identifier, thereby reducing the impact of the removal procedure for the first measurement object on the delay measurement. In other words, if the network device determines that the terminal device does not support retaining the first measurement identifier associated with the delay measurement in the removal procedure for the first measurement object, the network device may not initiate the removal procedure for the first measurement object (e.g., not initiate it before the delay measurement is completed), thereby avoiding a case where the removal procedure for the first measurement object causes the delay measurement procedure to fail.

[0073] According to an eighth aspect, there is provided a communication method. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, hereinafter, network An example in which a device executes the method is used for explanation.

[0074] The method includes: a network device transmitting second measurement configuration information, the second measurement configuration information indicating removal of a first measurement target; the network device receiving a measurement result of a delay measurement corresponding to the first measurement identifier reported by the terminal device by using a first identifier, the first identifier being different from the first measurement identifier; and the delay measurement including a packet data convergence protocol data packet average delay measurement and / or a packet data convergence protocol excess data packet delay measurement.

[0075] According to the above solution, in the removal procedure of the first measurement object, the network device can receive the measurement result of the delay measurement corresponding to the first measurement identifier reported by the terminal device by using the first identifier. In other words, even if the first measurement identifier is removed in the removal procedure of the first measurement object, the terminal device can still report the measurement result of the delay measurement by using a first identifier different from the first measurement identifier. This avoids the influence of the removal procedure of the first measurement object on the delay measurement procedure of the terminal device, thereby improving the service performance of the terminal device.

[0076] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0077] In one possible approach, receiving by the network device a measurement result of a delay measurement corresponding to a first measurement identifier reported by a terminal device by using the first identifier includes receiving by the network device a measurement result reported by the terminal device, wherein the reported result is a measurement result reported by the terminal device based on a reporting configuration corresponding to the first measurement identifier, or the reported result is a measurement result reported by the terminal device based on a preset reporting configuration.

[0078] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the network device receiving third capability information, the third capability information indicating that the terminal device supports reporting measurement results of the delay measurement using the first identifier in a deletion procedure of the second measurement object associated with the delay measurement.

[0079] Based on the above solution, the network device may receive third capability information from the terminal device. Because the first measurement object is one of the second measurement objects, the network device may determine, based on the third capability information, that when the first measurement identifier is associated with a delay measurement, the terminal device supports reporting a measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier in a removal procedure for the first measurement object. Therefore, in this case, even if the network device initiates a removal procedure for the first measurement object before the delay measurement ends and the removal procedure causes the terminal device to remove the first measurement identifier associated with the delay measurement, the terminal device can still report the measurement result of the delay measurement using the first identifier. In other words, the removal procedure for the first measurement object initiated by the network device for the terminal device does not significantly affect the delay measurement of the terminal device. Therefore, the network device may determine, based on the second capability information, that it can initiate a removal procedure for the first measurement object. In other words, when a first measurement identifier is associated with a delay measurement, if the network device determines that the terminal device does not support reporting the measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier in the removal procedure of the first measurement object, the network device may not initiate the removal procedure of the first measurement object (e.g., not initiate before the delay measurement is completed), thereby avoiding a failure of the delay measurement procedure caused by the removal procedure of the first measurement object.

[0080] According to a ninth aspect, there is provided a communication method. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, hereinafter, network An example in which a device executes the method is used for explanation.

[0081] The method includes: a network device determining that a first measurement object is associated with a delay measurement and that the terminal device does not support performing a second operation in a procedure for changing the first measurement object, and the network device not triggering the procedure for changing the first measurement object before the delay measurement is completed. The second operation includes one or more of the following operations: the terminal device maintaining a reporting record corresponding to the first measurement identifier, the terminal device maintaining timing of a timer corresponding to the first measurement identifier, or the terminal device maintaining information associated with the first measurement identifier.

[0082] The first measurement identifier is associated with a first measurement object, and the first measurement identifier is associated with a delay measurement, and the delay measurement includes a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement.

[0083] Based on the above solution, when the network device determines that the terminal device does not support performing the second operation on the first measurement object in the first measurement object change procedure, the network device does not trigger the first measurement object change procedure before determining that the delay measurement is completed, thereby avoiding a decrease in delay measurement efficiency and a waste of resources on the terminal device due to the terminal device removing a reporting record corresponding to the first measurement identifier, stopping a timer corresponding to the first measurement identifier, or removing information associated with the first measurement identifier due to the first measurement object change procedure.

[0084] In one possible approach, the first measurement object is one of the second measurement objects, and the method further includes the network device receiving first capability information, wherein the first capability information indicates that the terminal device does not support one or more of the following in a procedure for changing the second measurement object associated with a delay measurement: not supporting keeping a reporting record corresponding to the second measurement identifier, not supporting keeping time of a timer corresponding to the second measurement identifier, or not supporting keeping information associated with the second measurement identifier, and the second measurement identifier is associated with the second measurement object, and the second measurement identifier is associated with the delay measurement.

[0085] In one possible approach, the first measurement identifier is associated with a delay measurement, and the reporting configuration associated with the first measurement identifier includes configuration information for Packet Data Convergence Protocol data packet average delay measurement and / or configuration information for Packet Data Convergence Protocol excess data packet delay measurement.

[0086] According to a tenth aspect, a communication method is provided. The method can be performed by a network device, or can be performed by a chip or circuit configured in the network device. This is not a limitation in this application. For convenience, the following uses an example in which the network device performs the method for description.

[0087] The method includes: a network device determining that a first measurement object is associated with a delay measurement; and the terminal device does not support retaining a first measurement identifier associated with the first measurement object in a removal procedure for the first measurement object, or reporting a measurement result of the delay measurement by using a first identifier different from the first measurement identifier when the first measurement identifier is removed, wherein the first measurement identifier is associated with the delay measurement, and the delay measurement includes a Packet Data Convergence Protocol data packet average delay measurement and / or a Packet Data Convergence Protocol excess data packet delay measurement. Before the delay measurement is completed, the network device does not trigger the removal procedure for the first measurement object.

[0088] Based on the above solution, when the network device determines in the removal procedure for the first measurement object that the terminal device does not support retaining the first measurement identifier associated with the delay measurement or using the first identifier to report the measurement result of the delay measurement corresponding to the first measurement identifier, the network device does not trigger the removal procedure for the first measurement object before determining that the delay measurement is completed, thereby avoiding a case where the terminal device removes the first measurement identifier in the removal procedure for the first measurement object and is unable to report the delay measurement result.

[0089] In one possible approach, the method further includes the network device receiving second capability information, the second capability information indicating that the terminal device does not support retaining a second measurement identifier associated with the second measurement object in a removal procedure for the second measurement object associated with the delay measurement, and the second measurement identifier being associated with the delay measurement; or the network device receiving third capability information, the third capability information indicating that the terminal device supports reporting measurement results of the delay measurement using the first identifier in a removal procedure for the second measurement object associated with the delay measurement.

[0111] FIG. 1 is a diagram of a communication system 100 applicable to one embodiment of this application.

[0112] 1, the communication system 100 may include one network device 120 and may further include at least one terminal device 110. A connection may be established between the terminal device 110 and the network device 120 for communication.

[0113] A terminal device in embodiments of this application may be a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal in the embodiments of this application may be a mobile phone, a tablet computer (pad), a computer with wireless transmission and reception capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, 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 capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a 5G network, or a terminal in a future evolved network.

[0114] Wearable devices, sometimes referred to as wearable intelligent devices, are a general term for wearable devices, such as eyeglasses, gloves, watches, clothing, and shoes, that are intelligently designed and developed for everyday wear through wearable technology. Wearable devices are portable devices that are worn directly on a user's body or integrated into a user's clothing or accessories. Wearable devices are not only hardware devices, but also implement powerful functions through software support, data exchange, and cloud interaction. General-purpose wearable intelligent devices include full-featured, large-sized devices, such as smart watches or smart glasses, that can implement full or partial functions independently of a smartphone, as well as devices that focus on only one type of application function and need to work with another device, such as a smartphone, such as various smart bands or smart jewelry for monitoring body signs.

[0115] Alternatively, the terminal device may be a terminal device in an Internet of Things (IoT) system. IoT is an important part of the future development of information technology. The main technical feature of IoT is that items are connected to a network by using communication technologies to implement an intelligent network of man-machine interconnections and interconnections between items. The specific form of the terminal device is not limited in this application.

[0116] It should be understood that in the embodiments of this application, the terminal device may be a device configured to implement the functions of the terminal device, or may be a device capable of supporting the terminal device in implementing the functions, such as a chip system, which may be mounted in the terminal. In the embodiments of this application, the chip system may include a chip, or may include a chip and other discrete components.

[0117] The network device in the embodiments of this application may be any device with wireless receiving and transmitting capabilities. The device may include, but is not limited to, an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved NodeB or home NodeB (HNB)), a baseband unit (BBU), an access point (AP), a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. in a wireless fidelity (Wi-Fi) system, or may be a gNB or a transmission point (TRP or TP) in a 5G system, such as an NR system, or one antenna panel or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or may be, for example, a baseband unit (BBU) or a distributed unit (DBU). It may be a network node forming a gNB or a transmission point, such as a gNB (Gigabit Node B) or a DU (Gigabit Node B).

[0118] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, while the DU implements some of the gNB's functions. For example, the CU is responsible for processing non-real-time protocols and services and implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services and implementing the functions of the radio link control (RLC) layer, media access control (MAC) layer, and physical (PHY) layer. The AAU implements some physical layer processing functions, radio frequency processing, and functions related to active antennas. Information at the RRC layer is ultimately converted to or from information at the PHY layer. Therefore, in this architecture, higher layer signaling, such as RRC layer signaling, can also be considered to be transmitted by the DU or transmitted by the DU and the AAU. It can be understood that a network device may be a device including one or more of a CU node, a DU node, and an AAU node. Also, a CU may be classified as a network device in an access network (radio access network, RAN), or a CU may be classified as a network device in a core network (CN). This is not a limitation in this application.

[0119] It should be understood that in the embodiments of this application, a network device may be a device configured to implement the functions of the network device, or may be a device capable of supporting the network device in implementing the functions, such as a chip system, which may be mounted within the network device.

[0120] The technical solutions provided in this application may be applied to various communication systems, such as 5th generation (5G) systems or new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, and LTE time division duplex (TDD) systems. The technical solutions provided in this application may also be applied to future communication systems, such as 6th generation mobile communication systems. The technical solutions provided in this application may also be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine type communication (MTC), internet of things (IoT) communication systems, or other communication systems.

[0121] It should be understood that this application may apply to independently deployed 5G or LTE systems, or to non-independently deployed 5G or LTE systems, such as DC scenarios, including evolved universal terrestrial radio access - NR dual connectivity (EN-DC) and the like, and carrier aggregation (CA) scenarios.

[0122] In order to facilitate understanding of the technical solutions in the embodiments of this application, before describing the solutions in the embodiments of this application based on 5G architecture, some terms or concepts that may be used in the embodiments of this application will first be described.

[0123] 1. Measurement Object (MeasObject) A measurement object is an object measured by a UE. For example, an NR measurement object configuration may include a synchronization signal and physical broadcast channel block (SSB) configuration, an SSB Measurement Time Configuration (SMTC) configuration, a Channel State Information Reference Signal (CSI-RS) configuration, trustlist cells (also referred to as allowlist cells), and blocklist cells (also referred to as exclude-list cells). An LTE measurement object configuration may include an E-UTRA carrier frequency, a maximum allowed measurement bandwidth, trustlist cells (also referred to as allowlist cells), and blocklist cells (also referred to as exclude-list cells).

[0124] 2. Reporting Configurations The reporting configuration includes a criteria configuration for triggering the reporting of a measurement report, a format configuration of the measurement report, etc. Each reporting configuration has an independent reporting configuration identifier (reportConfigId) and can be classified based on its type as an event-triggered reporting configuration or a periodic reporting configuration, etc.

[0125] The event trigger reporting configuration may include an event category, a threshold, a trigger time (timeToTrigger) to meet the trigger condition, the number of measurements that need to be reported, and a reference signal type, etc. Measurement events include events A1 to A6 and events B1 and B2, etc.

[0126] The periodic reporting configuration may include a report interval (reportInterval), a reference signal type, a measurement quantity that needs to be reported, and a reference signal type, etc. The periodic reporting configuration may further include a PDCP packet delay measurement configuration (ul-DelayValueConfig-r16) and / or a PDCP excess delay measurement configuration (ul-ExcessDelayConfig-r17).

[0127] 3. Uplink PDCP Data Packet Average Delay Measurement (UL PDCP Packet Average Delay per DRB per UE) The uplink PDCP data packet average delay measurement is used to measure the PDCP queuing delay on the DRB in the UE. The delay is measured from the time a data packet arrives at the PDCP upper layer to the time an uplink grant is available to transmit the data packet. The purpose of this measurement is to perform QoS verification or QoS monitoring. No reference signal at the measurement target is used for the measurement.

[0128] 4. Uplink PDCP Excess Data Packet Delay Measurement (UL PDCP Excess Packet Delay per DRB) The uplink PDCP excess data packet delay measurement is used to measure the ratio of the delay of PDCP data packets that exceed a set delay threshold on a DRB in a UE. The delay of each data packet is the delay from the time the data packet arrives at the PDCP upper layer to the time when an uplink grant for transmitting the data packet becomes available. The purpose of this measurement is to perform QoS verification or QoS monitoring, etc. The reference signal in the measurement target is not used for the measurement.

[0129] 5. Event A3 Event A3 is an event of the event trigger report type. This event evaluates whether the signal quality of an adjacent cell is higher than that of the serving cell by a specific offset. The entry condition is Mn + Ofn + Ocn - Hys > Mp + Ofp + Ocp + Off. The exit condition is Mn + Ofn + Ocn + Hys < Mp + Ofp + Ocp + Off. The specific meanings of the related variables in the conditional expression are as follows.

[0130] Mp and Mn represent the measurement results of the serving cell and the adjacent cell, respectively.

[0131] Hys represents the amplitude hysteresis of the measurement result.

[0132] Ofp and Ofn represent the frequency offsets of the serving cell and the adjacent cell, respectively.

[0133] Ocp and Ocn represent the cell offsets of the serving cell and the adjacent cell, respectively.

[0134] Off represents the offset of Event A3.

[0135] The serving cell can be a special cell (SpCell). Specifically, the SpCell can be a primary cell (PCell) and / or a primary secondary cell (PSCell).

[0136] The UE can trigger a measurement report when the entry condition is continuously satisfied within the trigger time (TimeToTrigger).

[0137] 6. Event A5 Event A5 is an event of the event trigger report type. This event evaluates whether the signal quality of the serving cell is lower than threshold 1 or whether the signal quality of the adjacent cell is higher than threshold 2. The entry condition is Mp + Hys < Thresh1 and Mn + Ofn + Ocn - Hys > Thresh2. The exit condition is Mp - Hys > Thresh1 or Mn + Ofn + Ocn + Hys < Thresh2.

[0138] Mp and Mn represent the measurement results of the serving cell and the adjacent cell, respectively.

[0139] Hys represents the amplitude hysteresis of the measurement result.

[0140] Thresh1 and Thresh2 represent thresholds.

[0141] Ofn represents the frequency offset of the adjacent cell.

[0142] [[ID=Z30]]Ocn represents the cell offset of the adjacent cell.

[0143] The serving cell can be an SpCell. Specifically, the SpCell can be a PCell and / or a PSCell.

[0144] The UE can trigger a measurement report when the entry condition is continuously satisfied within the trigger time (TimeToTrigger).

[0145] 7. Measurement Identifier (MeasId) One measurement identifier (measurement ID) associates one measurement object configuration with one reporting configuration. The UE measures the measurement object associated with the measurement ID based on the measurement ID according to the requirements of the reporting configuration. When the UE sends a measurement report to the base station, the UE indicates the measurement ID corresponding to the measurement result to be reported, and the base station can determine the corresponding measurement object and reporting configuration based on the measurement ID.

[0146] 8. Measurement Reporting Method Based on the reporting configuration, the UE can send a measurement report for a specific measurement one or more times. Specifically, the reporting configuration may include a report amount parameter and a report interval parameter. The report amount indicates the number of times the UE needs to send a measurement report for a specific measurement after a report for the measurement is triggered. The report interval indicates the time interval at which the UE sends a measurement report. For example, if the report amount for a specific measurement is 1 (i.e., report amount = 1), the UE sends a measurement report only once after a report for the measurement is triggered. In another example, if the report amount for a specific measurement is N (i.e., report amount = N, where N is greater than 1), the UE sends a measurement report N times after a report for the measurement is triggered, and the time interval between two measurement reports is report interval.

[0147] 9. Measurement Report (MeasResults) The measurement report may include a measurement identifier (MeasId), a serving cell measurement result (measResultServingMOList), a neighbor cell measurement result (measResultNeighCells), etc. In particular, if the measurement associated with the measurement identifier is a PDCP delay measurement, a PDCP delay measurement result (ul-PDCP-DelayValueResultList-r16) and / or a PDCP excess delay measurement result (ul-PDCP-ExcessDelayResultList-r17) may be included.

[0148] 10. Bandwidth part (BWP) The maximum bandwidth of a 5G NR system can reach 400 MHz. However, due to the diversity of 5G services, from the UE's perspective, some services of a specific UE may not require a large transmission bandwidth. In addition, supporting a large transmission bandwidth also means high terminal costs. Therefore, the concept of BWP (Bandwidth Portion) has been proposed in the 3GPP protocol for 5G NR.

[0149] BWP refers to a segment of contiguous spectrum resources configured by the network side for the UE, and the UE transmits data over the BWP. The BWP may be smaller than the maximum transmission bandwidth of the network side. Therefore, flexible transmission bandwidth configuration on the network side and the UE side is implemented.

[0150] 11. Reduced capability UE (RedCap UE) RedCap UE is a technology for further enhancement to 5G NR. The capabilities of such a type of terminal are lower than those in enhanced mobile broadband (eMBB) and ultra-reliable and low latency communication (URLLC). For example, RedCap UE may have the following reduced functional complexity: reduced maximum bandwidth capability, reduced number of transmit / receive antennas / antenna channels (branches), reduced maximum number of multiple-input multiple-output (MIMO) layers, and reduced maximum modulation order capability.

[0151] Hereinafter, the solution provided in the embodiment of this application will be described in detail with reference to FIGS.

[0152] A network device can provide a terminal device with measurement configuration information related to delay measurement, so that the terminal device can perform a delay measurement procedure, such as performing a delay measurement and reporting a measurement result of the delay measurement, based on the measurement configuration information. However, if the network device initiates a measurement target change procedure during the process of the terminal device performing the delay measurement, the delay measurement procedure may be affected. For example, the reporting of the delay measurement result by the terminal device may be affected. As a result, the efficiency of the delay measurement procedure may be affected, or the delay measurement procedure may even fail. Therefore, how to reduce the impact of the measurement target change procedure on the delay measurement procedure of the terminal device in order to provide the service performance of the terminal device is an issue that currently needs to be considered.

[0153] Based on the above problem, Figure 2 is a flowchart example of a method 200 according to an embodiment of this application. The method 200 can improve the efficiency of delay measurement in the first measurement object change procedure and save resources of the terminal device. Below, an illustrative example of the method 200 is provided with reference to the steps of Figure 2.

[0154] Optionally, in S201, the terminal device sends first capability information to the network device, and in response, the network device receives the first capability information from the terminal device.

[0155] It may be understood that the manner and opportunity for the terminal device to transmit the first capability information to the network device are not limited in this application. For example, the terminal device may reuse an existing message in the capability query procedure to transmit the first capability information to the network device, or may transmit the first capability information to the network device in a separate procedure. This is not limited in this application.

[0156] In a first possible example, the first capability information is information that the terminal device performs in a procedure for changing a second measurement target associated with delay measurement: indicates support for one or more of: supporting keeping a reporting record corresponding to a second measurement identifier; supporting keeping a timer corresponding to a second measurement identifier; or supporting keeping information associated with a second measurement identifier, wherein the second measurement identifier is associated with a second measurement object and the second measurement identifier is associated with a delay measurement.

[0157] The delay measurements include packet data convergence protocol data packet average delay measurements and / or packet data convergence protocol excess data packet delay measurements.

[0158] The second measurement object may be any measurement object associated with a delay measurement. A measurement object associated with a delay measurement may mean that at least one measurement identifier of the one or more measurement identifiers associated with the measurement object is associated with the delay measurement. In other words, the first capability information indicates that the terminal device supports one or more operations indicated by the first capability information in a procedure for changing a measurement object associated with a delay measurement.

[0159] The second measurement identifier may be a measurement identifier associated with a delay measurement among one or more measurement identifiers associated with the second measurement object. A measurement identifier associated with a delay measurement may mean that a reporting configuration corresponding to the measurement identifier includes configuration information for the delay measurement, or that the measurement identifier is used to report a measurement result of the delay measurement.

[0160] S202: The network device transmits first measurement configuration information to the terminal device, and correspondingly, the terminal device receives the first measurement configuration information from the network device.

[0161] For example, the first measurement configuration information indicates to change a first measurement object, and the first measurement object is associated with a first measurement identifier.

[0162] It may be understood that the first measurement object may be configured for the terminal device by the network device. For example, before S202, the network device transmits third measurement configuration information to the terminal device, the third measurement configuration information including the first measurement object configuration and one or more measurement identifiers associated with the first measurement object, the one or more measurement identifiers including the first measurement identifier. The third measurement configuration information further includes information such as a reporting configuration corresponding to the first measurement identifier.

[0163] Optionally, when the first measurement identifier is associated with the delay measurement, the network device may trigger the first measurement object modification procedure (i.e., send the first measurement configuration information) if it determines that the terminal device supports performing a second operation in the first measurement object modification procedure, wherein the second operation includes one or more of the following operations: the terminal device retaining a reporting record corresponding to the first measurement identifier, the terminal device maintaining a timer corresponding to the first measurement identifier, or the terminal device retaining information associated with the first measurement identifier.

[0164] For example, the network device may determine that the terminal device supports performing a second operation in the procedure for changing the first measurement object based on the first capability information received in S201. It may be understood that the first measurement object is one of the second measurement objects.

[0165] Optionally, after the terminal device receives the first measurement configuration information, when the terminal device determines that the first measurement configuration information is used to change the first measurement target, the terminal device determines whether the first measurement identifier is associated with a delay measurement. For example, the terminal device determines whether the reporting configuration associated with the first measurement identifier includes configuration information for packet data convergence protocol data packet average delay measurement and / or configuration information for packet data convergence protocol overage data packet delay measurement. If the reporting configuration associated with the first measurement identifier includes configuration information for packet data convergence protocol data packet average delay measurement and / or configuration information for packet data convergence protocol overage data packet delay measurement, the terminal device determines that the first measurement identifier is associated with the delay measurement. If the reporting configuration associated with the first measurement identifier does not include configuration information for packet data convergence protocol data packet average delay measurement and / or configuration information for packet data convergence protocol overage data packet delay measurement, the terminal device determines that the first measurement identifier is not associated with a delay measurement. The packet data convergence protocol data packet average delay measurement configuration information may also be referred to as an uplink delay value configuration (Uplink-DelayValueConfig), and the uplink delay value configuration is used by the terminal device to perform uplink packet data convergence protocol data packet average delay measurement.The packet data convergence protocol excess data packet delay measurement configuration information may also be referred to as an uplink excess delay configuration (Uplink-ExcessDelayConfig), and the uplink excess delay configuration is used by a terminal device to perform uplink packet data convergence protocol excess data packet delay measurement.

[0166] Furthermore, the terminal device performs different operations based on the result of the determination. It can be understood that when the first measurement object is associated with multiple measurement identifiers, the terminal device may perform the above-mentioned determination for each measurement identifier and perform different operations for each measurement identifier based on the result of the determination. The following describes the two cases separately using examples.

[0167] Case 1: S203a: When the first measurement identifier is not associated with the delay measurement, the terminal device performs a first operation.

[0168] For example, the first action may include one or more of the following actions: the terminal device removing a reporting record corresponding to the first measurement identifier; the terminal device stopping a timer corresponding to the first measurement identifier; or the terminal device resetting information associated with the first measurement identifier.

[0169] For example, the report record corresponding to the first measurement identifier includes one or more of a first measurement identifier, a trigger cell list, a report count, a trigger reference signal list, a trigger source list, or a trigger resource pool list, etc. The trigger cell list includes information about cells that satisfy a reporting condition, and the report count is the number of times that the terminal device has reported a measurement report to the network device. The trigger reference signal list includes information about reference signals that satisfy the reporting condition, the trigger source list includes sidelink sources that satisfy the reporting condition, and the trigger resource pool list includes sidelink resource pools that satisfy the reporting condition. The timer corresponding to the first measurement identifier includes one or more of the following timers: a periodic reporting timer, timer T321, or timer T322. The periodic reporting timer is used to control the time interval at which the terminal device reports a measurement report corresponding to the first measurement identifier. The timer T321 is used to control the terminal device to report cell global identifier (CGI) information. The timer T322 is used to control the terminal device to report system frame number (SFN) and frame timing difference (SFTD) information. The information associated with the first measurement identifier can be, for example, trigger time information (timeToTrigger).

[0170] Case 2: S203b: When the first measurement identifier is associated with the delay measurement, the terminal device performs a second operation.

[0171] For example, the second operation includes one or more of the following operations: the terminal device maintaining a reporting record corresponding to the first measurement identifier; the terminal device maintaining the timing of a timer corresponding to the first measurement identifier; or the terminal device maintaining information associated with the first measurement identifier.

[0172] The fact that the terminal device retains the reporting record corresponding to the first measurement identifier means that the terminal device does not remove (or delete) the reporting record corresponding to the first measurement identifier. Therefore, in this case, during the first measurement object change procedure (or after the first measurement object is changed), the terminal device can still perform delay measurement and / or report the measurement result of the delay measurement based on the existing reporting record. There is no need to regenerate the reporting record, and as a result, unnecessary re-reporting can be avoided. For example, the reporting configuration corresponding to the first measurement identifier indicates that the number of reports is 8, i.e., the terminal device needs to report the measurement result 8 times. Assume that the network device triggers the first measurement object change procedure after the terminal device has reported the measurement result 4 times. In this case, if the terminal device removes the reporting record, the terminal device needs to re-report the measurement result 8 times. This affects delay measurement efficiency, causes additional measurement result reporting (e.g., in the above example, the terminal device may end up reporting the measurement result 12 times), and results in unnecessary signaling overhead. However, in the solution of method 200, the terminal device keeps a reporting record corresponding to the first measurement identifier in the first measurement object change procedure, so that the terminal device can continue to report the measurement result of the delay measurement based on the reporting configuration corresponding to the first measurement identifier, thereby improving efficiency and saving resources.

[0173] The terminal device maintaining the timer corresponding to the first measurement identifier means that when the timer corresponding to the first measurement identifier is running, the terminal device can keep the timer running without stopping it. Therefore, in this case, in the first measurement object change procedure (or after the first measurement object is changed), the terminal device does not need to reset the timer and can report the delay measurement result based on the original report interval (reportInterval), thereby improving efficiency, saving resources, and avoiding the case where the measurement result is not reported because it is not reported based on the report interval configured by the network device.

[0174] The fact that the terminal device retains the information associated with the first measurement identifier means that the terminal device does not reset the information associated with the first measurement identifier, for example, the trigger time (timeToTrigger) information associated with the first measurement identifier is not reset, which may result in improved efficiency.

[0175] In short, in the above solution, when the first measurement identifier is associated with a delay measurement, the terminal device does not reset or remove information (i.e., information such as the reporting record and timer in the above example) associated with the first measurement identifier and used for the measurement (or used for reporting the measurement result) in the first measurement target change procedure, so that the terminal device can continue to report the measurement result of the delay measurement based on such information, thereby improving the delay measurement efficiency, avoiding unnecessary signaling overhead, and improving the service performance of the terminal device.

[0176] It can be understood that in the procedure for changing the first measurement object, both Case 1 and Case 2 can occur; for example, in the procedure for changing the first measurement object, some of the measurement identifiers associated with the first measurement object correspond to Case 1, and some of the measurement identifiers correspond to Case 2. In another example, in the procedure for changing the first measurement object, all of the measurement identifiers associated with the first measurement object correspond to Case 1, or all of the measurement identifiers associated with the first measurement object correspond to Case 2.

[0177] In the above solution, when the first measurement identifier is associated with a delay measurement, the network device may trigger the first measurement object modification procedure (i.e., send the first measurement configuration information) if it determines that the terminal device supports performing the second operation in the first measurement object modification procedure. In another possible implementation, if the network device determines that the terminal device does not support performing the second operation in the first measurement object modification procedure, the network device may not trigger the first measurement object modification procedure before the delay measurement corresponding to the first measurement identifier is completed. This implementation is described below using an example.

[0178] In another possible example 2, the first capability information transmitted by the terminal device to the network device in S201 is transmitted by the terminal device in a second measurement target change procedure associated with delay measurement, Supporting the maintenance of a reporting record corresponding to the second measurement identifier, supporting the maintenance of a timer corresponding to the second measurement identifier, or supporting the maintenance of information associated with the second measurement identifier; where the second measurement identifier is associated with the second measurement object and the second measurement identifier is associated with the delay measurement.

[0179] In another possible example, the terminal device does not transmit the first capability information to the network device. Since the network device does not receive the first capability information, the network device determines that the terminal device: Supporting the maintenance of a reporting record corresponding to the second measurement identifier, supporting the maintenance of a timer corresponding to the second measurement identifier, or supporting the maintenance of information associated with the second measurement identifier; and determine that the first capability information does not support one or more of the following, where the second measurement identifier is associated with the second measurement object, and the second measurement identifier is associated with the delay measurement. For a definition of the first capability information, please refer to the description in Possible Example 1 above. Details will not be described again here.

[0180] The network device may determine, based on the first capability information, that the terminal device does not support performing a second operation in the first measurement target change procedure.

[0181] In this case, the network device does not trigger the procedure for changing the first measurement object before the delay measurement corresponding to the first measurement identifier is completed. In other words, the network device triggers the procedure for changing the first measurement object only after the delay measurement corresponding to the first measurement identifier is completed. After receiving the measurement result of the delay measurement corresponding to the first measurement identifier, the network device may determine that the delay measurement is completed.

[0182] Based on the above solution, before the delay measurement is completed, the network device does not trigger the measurement target change procedure associated with the delay measurement, and the influence of the measurement target change procedure on the delay measurement is avoided.

[0183] A network device can provide a terminal device with measurement configuration information related to delay measurement, so that the terminal device can perform a delay measurement procedure, such as performing a delay measurement, and report a measurement result of the delay measurement based on the measurement configuration information. However, if the network device initiates a measurement object removal procedure (also referred to as a deletion procedure) during the process of the terminal device performing the delay measurement, the delay measurement procedure may be affected. For example, reporting of the delay measurement result by the terminal device may be affected, resulting in a measurement result report failure. Therefore, how to reduce the impact of the measurement object removal procedure on the delay measurement procedure of the terminal device in order to improve the success rate of the delay measurement procedure is currently a problem that needs to be considered.

[0184] Based on the above problem, Figure 3 is a flowchart example of a method 300 according to an embodiment of the present application. In the method 300, the removal procedure of the first measurement object does not affect the reporting of the measurement result of the delay measurement by the terminal device, thereby avoiding a case where the removal procedure of the first measurement object causes the delay measurement procedure to fail. Below, an illustrative example of the method 300 is provided with reference to the steps of Figure 3.

[0185] Optionally, in S301, the terminal device sends second capability information to the network device, and in response, the network device receives the second capability information from the terminal device.

[0186] In a first possible example, the second capability information indicates that, in a removal procedure for a second measurement object associated with a delay measurement, the terminal device supports retaining a second measurement identifier associated with the second measurement object, and the second measurement identifier is associated with the delay measurement. The terminal device's support for retaining the second measurement identifier associated with the second measurement object means that the terminal device supports not deleting the second measurement identifier.

[0187] For the meaning of the second measurement object and the second measurement identifier, please refer to the description of the second measurement object and the second measurement identifier in S201 of the method 200. The details will not be described again here.

[0188] S302: The network device transmits second measurement configuration information to the terminal device. Correspondingly, the terminal device receives the second measurement configuration information from the network device.

[0189] For example, the second measurement configuration information indicates to remove a first measurement object, and the first measurement object is associated with a first measurement identifier.

[0190] Optionally, before S302, the network device may further determine whether the first measurement identifier is associated with a delay measurement. For example, the network device may determine whether a reporting configuration associated with the first measurement identifier includes configuration information for packet data convergence protocol data packet average delay measurement and / or packet data convergence protocol overage data packet delay measurement. If the reporting configuration associated with the first measurement identifier includes configuration information for packet data convergence protocol data packet average delay measurement and / or packet data convergence protocol overage data packet delay measurement, the network device determines that the first measurement identifier is associated with the delay measurement. If the reporting configuration associated with the first measurement identifier does not include configuration information for packet data convergence protocol data packet average delay measurement and / or packet data convergence protocol overage data packet delay measurement, the network device determines that the first measurement identifier is not associated with the delay measurement.

[0191] Optionally, when the first measurement identifier is associated with the delay measurement, the network device may trigger a removal procedure for the first measurement object (i.e., send second measurement configuration information) if it determines that the terminal device supports retaining the first measurement identifier in the removal procedure for the first measurement object. For example, the network device may determine that the terminal device supports retaining the first measurement identifier in the removal procedure for the first measurement object based on the second capability information received in S301. It may be understood that the first measurement object is one of the second measurement objects.

[0192] S303a: The network device removes the first measurement target.

[0193] S303b: The terminal device removes the first measurement target.

[0194] For example, the terminal device removes the first measurement target based on the second measurement configuration information.

[0195] And the network device performs different operations on the first measurement identifier based on the result of the determination. The following describes the two cases separately using examples.

[0196] Case a: The network device removes the first measurement identifier when the first measurement identifier is not associated with a delay measurement.

[0197] Case b: The network device retains the first measurement identifier when the first measurement identifier is associated with a delay measurement. The network device retaining the first measurement identifier means that the network device does not delete the first measurement identifier.

[0198] It can be understood that when a first measurement identifier is associated with a delay measurement, the first measurement identifier can be used by the terminal device to report a measurement result of the delay measurement, and the network device can determine, based on the first measurement identifier, that the measurement result reported by the terminal device is the measurement result of the delay measurement. Therefore, if the network device deletes the first measurement identifier, after the terminal device reports the measurement result of the delay measurement, the network device cannot identify the measurement result, resulting in a failure of the delay measurement procedure. However, in the above solution, the network device can retain the first measurement identifier associated with the delay measurement in the first measurement object removal procedure. Therefore, it is possible to avoid a case where the delay measurement procedure fails because the network device deletes the first measurement identifier.

[0199] Optionally, after the terminal device receives the second measurement configuration information, when the terminal device determines that the second measurement configuration information is used to remove the second measurement object, the terminal device determines whether the first measurement identifier is associated with the delay measurement. For a specific manner, please refer to the description of S201 in method 200. Details will not be described here.

[0200] It can be understood that the order in which S302, S303a, and S304a / S304b are performed by the network device is not limited in this application, and the order in which S303b and S305a / S305b are performed by the terminal device is not limited in this application.

[0201] And the terminal device performs different operations on the first measurement identifier according to the result of the determination. The following describes the two cases separately using examples.

[0202] Case a': The terminal device removes the first measurement identifier when the first measurement identifier is not associated with the delay measurement.

[0203] Case b': The terminal device retains the first measurement identifier when the first measurement identifier is associated with the delay measurement. The terminal device retaining the first measurement identifier means that the terminal device does not delete the first measurement identifier.

[0204] In case b', the terminal device may report the measurement result of the delay measurement associated with the first measurement identifier to the network device. In other words, the terminal device may report the measurement result of the delay measurement to the network device by using the first measurement identifier. The terminal device may report the measurement result based on the reporting configuration corresponding to the first measurement identifier.

[0205] Therefore, based on the above solution, the terminal device can retain the first measurement identifier associated with the delay measurement during the first measurement object removal procedure, thus avoiding the case where the delay measurement procedure fails when the terminal device cannot report the delay measurement result because it has deleted the first measurement identifier.

[0206] Optionally, after receiving a measurement result of the delay measurement associated with the first measurement identifier, the network device removes the first measurement identifier.

[0207] Optionally, after receiving a measurement result of the delay measurement associated with the first measurement identifier, the network device sends fourth measurement configuration information to the terminal device, where the fourth measurement configuration information indicates to remove the first measurement identifier.

[0208] Optionally, after reporting the measurement result of the delay measurement corresponding to the first measurement identifier, the terminal device removes the first measurement identifier. For example, the terminal device receives fourth measurement configuration information from the network device and removes the first measurement identifier based on the fourth measurement configuration information. In another example, the terminal device autonomously removes the first measurement identifier.

[0209] Therefore, based on the above solution, the terminal device and the network device can remove the first measurement identifier after the delay measurement is completed, thereby reducing resource occupation.

[0210] In the above solution, when the first measurement identifier is associated with a delay measurement, the network device may trigger the removal procedure for the first measurement object (i.e., send the second measurement configuration information) if it determines that the terminal device supports retaining the first measurement identifier in the removal procedure for the first measurement object. In another possible implementation, if the network device determines that the terminal device does not support retaining the first measurement identifier in the removal procedure for the first measurement object, the network device may not trigger the removal procedure for the first measurement object before the delay measurement corresponding to the first measurement identifier is completed. This implementation is described below using an example.

[0211] In another possible example 2, the second capability information sent by the terminal device to the network device in S301 indicates that the terminal device does not support retaining a second measurement identifier in a removal procedure for a second measurement object associated with the delay measurement, and that the second measurement identifier is associated with the delay measurement.

[0212] In another possible example, the terminal device does not transmit the second capability information to the network device. Since the network device does not receive the second capability information, the network device determines that the terminal device does not support retaining the second measurement identifier in the removal procedure of the second measurement object associated with the delay measurement. For a definition of the second capability information, please refer to the description in the above possible example 1. Details will not be described again here.

[0213] The network device determines, based on the second capability information, that the terminal device does not support retaining the first measurement identifier in the removal procedure of the first measurement object.

[0214] In this case, the network device does not trigger the removal procedure for the first measurement object before the delay measurement associated with the first measurement object is completed. In other words, the network device triggers the removal procedure for the first measurement object only after the delay measurement corresponding to the first measurement identifier is completed. After receiving the measurement result of the delay measurement corresponding to the first measurement identifier, the network device may determine that the delay measurement is completed.

[0215] Based on the above solution, before the delay measurement is completed, the network device does not trigger the measurement object removal procedure associated with the delay measurement, and the influence of the measurement object removal procedure on the delay measurement procedure is avoided.

[0216] It may be appreciated that method 300 may be implemented independently or in combination with method 200. In one implementation, the first capability information and the second capability information may be carried in the same message, the same information element, or the same field.

[0217] 4 is an example flowchart of a method 400 according to an embodiment of the present application. In the method 400, when a first measurement identifier associated with a delay measurement is removed in a first measurement object removal procedure, the reporting of the measurement result of the delay measurement by the terminal device is not affected, thereby avoiding a case where the first measurement object removal procedure causes a failure of the delay measurement procedure. Below, an illustrative example of the method 400 is provided with reference to the steps of FIG. 4.

[0218] Optionally, in S401, the terminal device sends third capability information to the network device, and in response, the network device receives the third capability information from the terminal device.

[0219] In a first possible example, the third capability information indicates that the terminal device supports reporting measurement results of a delay measurement using a first identifier in a removal procedure of a second measurement object associated with the delay measurement, or the third capability information indicates that the terminal device supports reporting measurement results of a delay measurement corresponding to a second measurement identifier using a first identifier when the second measurement identifier associated with the delay measurement is removed.

[0220] For the meaning of the second measurement object and the second measurement identifier, please refer to the description of the second measurement object and the second measurement identifier in S201 of the method 200. The details will not be described again here.

[0221] S402: The network device transmits second measurement configuration information to the terminal device. Correspondingly, the terminal device receives the second measurement configuration information from the network device.

[0222] For example, the second measurement configuration information indicates to remove a first measurement object, and the first measurement object is associated with a first measurement identifier.

[0223] Optionally, before S402, the network device may further determine whether the first measurement identifier is associated with the delay measurement. For a specific manner, please refer to the description of S302 in method 300. Details will not be described here.

[0224] Optionally, when the network device determines in the removal procedure for the first measurement object that the terminal device supports reporting the measurement result of the delay measurement corresponding to the first measurement identifier using the first identifier, the network device may trigger the removal procedure for the first measurement object (i.e., transmit the second measurement configuration information). For example, the network device may determine, based on the third capability information received in S401, in the removal procedure for the first measurement object that the terminal device supports reporting the measurement result of the delay measurement corresponding to the first measurement identifier using the first identifier. It may be understood that the first measurement object is one of the second measurement objects.

[0225] S403a: The network device removes the first measurement target.

[0226] S403b: The terminal device removes the first measurement object.

[0227] For example, the terminal device removes the first measurement target based on the second measurement configuration information.

[0228] S 404a : The network device removes the first measurement identifier.

[0229] S404b: The terminal device removes the first measurement identifier.

[0230] For example, after the terminal device receives second measurement configuration information, when the terminal device determines that the second measurement configuration information is to be used to remove a first measurement object, the terminal device removes the first measurement identifier associated with the first measurement object.

[0231] It can be understood that the order in which S402, S403a, and S404a are performed by the network device is not limited in this application, and the order in which S403b and S404b are performed by the terminal device is not limited in this application.

[0232] S405: The terminal device reports a measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier.

[0233] For example, after the first measurement identifier is removed, the terminal device reports the measurement result of the delay measurement corresponding to the first measurement identifier by using a first identifier different from the first measurement identifier.

[0234] The first identifier may be a preconfigured identifier, an identifier specified in a protocol, or an identifier determined through negotiation between the terminal device and the network device. The first identifier may be an identifier specifically used to report delay measurement results in a measurement object removal procedure, or an identifier used in other procedures. This is not a limitation of this application. The value of the first identifier is not a limitation of this application. In one example, the first identifier may be used as a special measurement identifier. Since the value range of a measurement identifier is 1 to 64, the value of the first identifier may be any reserved value between 1 and 64. Alternatively, the value of the first identifier may be a value other than 1 to 64. For example, the value of the first identifier may be 0. This is not a limitation of this application. The first identifier is used to report delay measurement results corresponding to a measurement identifier associated with the delay measurement when the measurement identifier is deleted. The first identifier may include one or more identifiers.

[0235] The manner in which the terminal device reports the delay measurement result by using the first identifier is not limited in this application. In one possible implementation, the terminal device reports the measurement result based on a reporting configuration corresponding to the first measurement identifier. In another possible implementation, the terminal device reports the measurement result based on a pre-configured reporting configuration.

[0236] Correspondingly, the network device receives the measurement result from the terminal device and determines, based on the first identifier, that the measurement result is a delay measurement result.

[0237] Based on the above-mentioned solution, when the first measurement identifier is removed in the removal procedure of the first measurement object, the terminal device can report the measurement result of the delay measurement using a first identifier different from the first measurement identifier, thereby avoiding a case where the measurement result of the delay measurement cannot be reported because the first measurement identifier is removed in the removal procedure of the first measurement object.

[0238] In the above solution, when a first measurement identifier is associated with a delay measurement, if the network device determines in the removal procedure for the first measurement object that the terminal device supports reporting the measurement result of the delay measurement corresponding to the first measurement identifier using the first identifier, the network device may trigger the removal procedure for the first measurement object (i.e., send the second measurement configuration information). In another possible implementation, if the network device determines in the removal procedure for the first measurement object that the terminal device does not support reporting the measurement result of the delay measurement corresponding to the first measurement identifier using the first identifier, the network device may not trigger the removal procedure for the first measurement object before the delay measurement corresponding to the first measurement identifier is completed. This implementation will be described below using an example.

[0239] In another possible example 2, the third capability information sent by the terminal device to the network device in S401 indicates that in a removal procedure for a second measurement object associated with the delay measurement, the terminal device does not support reporting the measurement result of the delay measurement corresponding to the second measurement identifier using the first identifier, and that the second measurement identifier is associated with the delay measurement.

[0240] In another possible example, the terminal device does not transmit the third capability information to the network device. Since the network device does not receive the third capability information, the network device determines that the terminal device does not support reporting the measurement result of the delay measurement corresponding to the second measurement identifier using the first identifier in the removal procedure of the second measurement object associated with the delay measurement. 3 For the definition of the capability information, please refer to the explanation in the above Possible Example 1. The details will not be explained again here.

[0241] Based on the third capability information, the network device determines that the terminal device does not support reporting measurement results of delay measurements corresponding to the first measurement identifier using the first identifier in the removal procedure of the first measurement object.

[0242] In this case, the network device does not trigger the removal procedure for the first measurement object before the delay measurement associated with the first measurement object is completed. In other words, the network device triggers the removal procedure for the first measurement object only after the delay measurement corresponding to the first measurement identifier is completed. After receiving the measurement result of the delay measurement corresponding to the first measurement identifier, the network device may determine that the delay measurement is completed.

[0243] Based on the above solution, before the delay measurement is completed, the network device does not trigger the measurement object removal procedure associated with the delay measurement, and the influence of the measurement object removal procedure on the delay measurement is avoided.

[0244] It may be understood that method 400 may be implemented independently or in combination with method 200 and / or method 300. In one implementation, two or three of the first capability information, the second capability information, and the third capability information may be carried in the same message, the same information element, or the same field.

[0245] It may be understood that when method 300 and method 400 are implemented in combination, if the terminal device not only supports retaining a first measurement identifier associated with a delay measurement in the removal procedure of the first measurement object, but also supports reporting the measurement result of the delay measurement corresponding to the first measurement identifier by using the first identifier in the removal procedure of the first measurement object, the network device may instruct the terminal device to report the measurement result of the delay measurement in any of these manners.

[0246] In some procedures, a terminal device performs cell measurements and reports cell measurement results to a network device. However, in some cases, the terminal device may make some invalid measurements or even report measurement results that mislead the network device. For example, the terminal device may report two measurements of the same cell. As a result, the terminal device's resources may be wasted or the terminal device may even perform an inappropriate handover. How to save the terminal device's resources and avoid inappropriate handovers that may occur in the terminal device's cell measurement process are currently issues that need to be considered.

[0247] Based on the above problem, Figure 5 is a schematic flowchart of a method 500 according to an embodiment of this application. The method 500 can prevent a terminal device from triggering a measurement report based on measurement results of the same cell, thereby reducing resource waste and avoiding inappropriate handover. 5 An illustrative example of the method 500 is provided with reference to the steps of:

[0248] S501: A terminal device obtains a first measurement result of a first cell and a second measurement result of a second cell.

[0249] For example, the first cell and the second cell are different cells, and the second cell is a serving cell of the terminal device.

[0250] It may be understood that the serving cell may be a special cell (SpCell), and the SpCell may be a primary cell (PCell) and / or a primary secondary cell (PSCell). The first cell is associated with a first measurement object, the second cell is associated with a second measurement object, the terminal device measures the first cell based on the first measurement object to obtain a first measurement result, and the terminal device measures the second cell based on the second measurement object to obtain a second measurement result.

[0251] S502: The terminal device evaluates whether the first measurement result and the second measurement result meet a reporting criterion.

[0252] For example, after obtaining the first measurement result and the second measurement result, the terminal device evaluates whether the first measurement result and the second measurement result satisfy a reporting criterion. In one implementation, the reporting criterion may be a reporting criterion in a reporting configuration associated with the first measurement object. This is not a limitation of this application.

[0253] When the reporting criteria are met, the terminal device reports a measurement report to the network device, where the measurement report includes the first measurement result and the second measurement result.

[0254] In one example, the reporting criteria may be Event A3 or Event A5. For example, the reporting criteria may include one or more of: a difference between the signal quality of the first cell and the signal quality of the second cell is greater than a first threshold, where the first threshold may be, for example, an offset; or the signal quality of the first cell is higher than a second threshold and the signal quality of the second cell is lower than a third threshold. It may be understood that the first measurement result includes the signal quality of the first cell and the second measurement result includes the signal quality of the second cell.

[0255] Optionally, the terminal device determines whether the first cell and the second cell are the same cell.

[0256] In one possible implementation, before S501, the terminal device may determine whether the first cell and the second cell are the same cell. For example, the terminal device receives fifth configuration information from the network device, and the fifth configuration information indicates that a first measurement object and a second measurement object are to be measured. The first cell is associated with the first measurement object, and the second cell is associated with the second measurement object. The terminal device determines whether the first cell and the second cell are the same cell. When the first cell and the second cell are different cells, the terminal device measures the first cell and the second cell separately to obtain the first measurement result and the second measurement result. When the first cell and the second cell are the same cell, the terminal device may not measure the first cell, or the terminal device may not measure the second cell. According to the above solution, unnecessary measurements can be reduced, thereby saving resources of the terminal device. Specifically, for example, the second cell is a PCell (or a PSCell). Before performing measurements, the terminal device determines whether the first cell is a PCell (or a PSCell). If the first cell is a PCell (or a PSCell), it indicates that the first cell and the second cell are the same cell. In this case, the terminal device does not measure the first cell or does not measure the second cell.

[0257] In another possible implementation, before S502, the terminal device may determine whether the first cell and the second cell are the same cell. For example, after obtaining the first measurement result and the second measurement result, the terminal device determines whether the first cell and the second cell are the same cell. If the first cell and the second cell are different cells, the terminal device evaluates whether the first measurement result and the second measurement result satisfy the reporting criteria. If the first cell and the second cell are the same cell, the terminal device does not evaluate whether the first measurement result and the second measurement result satisfy the reporting criteria. According to the above solution, it is possible to avoid resource waste caused by evaluating the measurement results of the same cell and reporting the measurement results of the same cell to the network device, and to avoid possible inappropriate handover. An inappropriate handover may occur when the terminal device initiates a cell handover procedure in the current serving cell and is handed over to that cell again. Specifically, for example, the second cell is a PCell (or a PSCell), and the terminal device determines whether the first cell is a PCell (or a PSCell). If the first cell is a PCell (or a PSCell), it indicates that the first cell and the second cell are the same cell. In this case, the terminal device does not evaluate whether the first measurement result and the second measurement result meet the reporting criteria.

[0258] In another possible implementation, after S502, the terminal device may determine whether the first cell and the second cell are the same cell. For example, after the terminal device acquires the first measurement result and the second measurement result, if the terminal device determines through evaluation that the first measurement result and the second measurement result meet a reporting criterion, the terminal device further determines whether the first cell and the second cell are the same cell. If the first cell and the second cell are different cells, the terminal device reports a measurement report to the network device, or if the first cell and the second cell are the same cell, the terminal device does not report a measurement report to the network device. According to the above solution, it is possible to avoid reporting a measurement report triggered by measurement results of the same cell to the network device, thereby reducing resource waste and avoiding inappropriate handover. For example, the second cell is a PCell (or a PSCell). When the terminal device obtains the first measurement result and the second measurement result and determines that the first measurement result and the second measurement result meet the reporting criteria, the terminal device determines whether the first cell is a PCell (or a PSCell). If the first cell is a PCell (or a PSCell), it indicates that the first cell and the second cell are the same cell. In this case, the terminal device does not report a measurement report triggered by the measurement result of the PCell (or a PSCell) to the network.

[0259] Based on the above solution, when the first cell and the second cell are different cells, the terminal device evaluates whether the first measurement result corresponding to the first cell and the second measurement result corresponding to the second cell meet the reporting criteria. When the first cell and the second cell are the same cell, the terminal device does not measure the first cell or the second cell, or does not evaluate whether the first measurement result and the second measurement result meet the reporting criteria, or does not report a measurement report corresponding to the first measurement result and the second measurement result. This prevents the terminal device from triggering a measurement report based on the measurement results of the same cell, thereby reducing resource waste and avoiding inappropriate handover.

[0260] In a specific example, the reporting configuration associated with the first measurement object includes the above-mentioned reporting criteria (e.g., Event A3 or Event A5). Assume that an SpCell is associated with the first measurement object and a second measurement object other than the first measurement object. Even if the second measurement object is a currently designated measurement object used to obtain the SpCell result, the terminal device does not use the SpCell associated with the first measurement object as a neighbor cell of the SpCell associated with the first measurement object. Therefore, it is possible to prevent the terminal device from triggering measurement reporting based on the measurement results of the same cell.

[0261] It can be understood that the above solution is described using an example in which the second cell is a serving cell of the terminal device and the first cell is a neighboring cell of the terminal device. However, in another possible implementation, both the first cell and the second cell may be neighboring cells of the terminal device. This is not a limitation in this application.

[0262] It can be further understood that in one possible implementation scenario, the second measurement object corresponds to an active bandwidth portion of the terminal device, and the first measurement object does not correspond to an active bandwidth portion of the terminal device. The above solution may be applied to a handover procedure in the active bandwidth portion.

[0263] It may be further understood that in one possible implementation scenario, the terminal device in method 500 may be a RedCap UE. In this case, the second cell is a PCell. Therefore, when the first cell is not a PCell, the terminal device determines that the first cell and the second cell are not the same cell. The second measurement object is a currently designated measurement object used to obtain the SpCell result, but the PCell on the first measurement object is not considered to be a neighboring cell.
