Description

Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 15, 2023, with application number 202311205476.4 and application name “A Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to a communication method and apparatus. Background Art

[0003] In wireless communication systems, when a terminal moves from one cell's coverage to another, a cell handover is required to ensure service continuity. Specifically, in the radio resource control (RRC) connected state (RRC_CONNECTED), the base station sends measurement configuration information to the terminal via an RRC reconfiguration message. The terminal performs cell measurements based on the measurement configuration information and submits a measurement report. The base station then determines the target cell or candidate cell for handover based on the measurement report.

[0004] The above measurement reporting mechanism may cause the target cell or candidate cell determined by the base station during the cell handover process to fail to meet the service requirements of the terminal and / or the operator.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus, which can ensure that a target cell or candidate cell determined by a wireless access network device meets the service requirements of a terminal device and / or an operator.

[0007] In a first aspect, a communication method is provided. The method can be executed by a terminal device, or by a component of the terminal device, such as a processor, chip, or chip system of the terminal device, or by a logic module or software capable of implementing all or part of the functions of the terminal device. The method includes: receiving first information, where the first information indicates the priority of one or more measurement objects; obtaining measurement intervals (GAPs) corresponding to one or more measurement object sets, where the one or more measurement object sets are determined based on the priority of the one or more measurement objects, and the measurement GAPs are used to measure the measurement object sets corresponding to the measurement GAPs.

[0008] Based on this solution, the terminal device can measure a measurement object set within the measurement GAP corresponding to the measurement object set, that is, the terminal device can measure different measurement object sets in different GAPs, that is, different measurement GAPs can be used according to different measurement object sets to ensure that the frequency indicated by each measurement object in the measurement object set can be fully measured. For example, in order to adapt the measurement duration of each measurement object in the measurement object set, a measurement GAP with a shorter duration may be used when there are fewer measurement objects in the measurement object set, and a measurement GAP with a longer duration may be used when there are more measurement objects in the measurement object set. Compared with the solution of configuring only one measurement GAP and completing the measurement of different measurement object sets within the one measurement GAP, on the one hand, it can avoid the degradation of transmission performance caused by too long a data transmission suspension time, and on the other hand, it can avoid the degradation of measurement performance caused by insufficient measurement duration.

[0009] In addition, since one or more measurement object sets are determined based on the priority of one or more measurement objects, the terminal device can select an appropriate measurement object set for measurement based on the priority. For example, a measurement object set including the highest priority can be selected for measurement. It can be understood that in different scenarios, the priority of the same measurement object may be different, so that the one or more measurement object sets determined based on the priority in different scenarios are also different. For example, the priority of one or more measurement objects can be set according to the business requirements of the terminal device, such as setting the priority of the measurement object that best meets the business requirements to the highest priority, and setting the priority of the measurement object that relatively meets the business requirements to the second highest priority, etc. Therefore, when selecting a measurement object set, the terminal device can give priority to the measurement object set that includes the highest priority and best meets the business requirements for measurement, thereby making the target cell found meet the business requirements as much as possible.

[0010] In one possible design, obtaining measurement GAPs corresponding to one or more measurement object sets includes: receiving an Nth measurement GAP corresponding to an Nth measurement object set in one or more measurement object sets, where N is a positive integer.

[0011] Based on this possible design, the terminal device can measure different measurement object sets in different measurement GAPs. That is, different measurement GAPs can be used according to different measurement object sets to ensure that the frequency points indicated by each measurement object in the measurement object set can be fully measured. For example, when there are fewer measurement objects in the measurement object set, the frequency points indicated by the measurement objects in the measurement object set are fewer. Therefore, the measurement duration (SSB search time window) of each frequency point in the fewer frequency points can be adapted, that is, a measurement GAP with a shorter duration is used. When there are more measurement objects in the measurement object set, the frequency points indicated by the measurement objects in the measurement object set are more. Therefore, in order to adapt to the measurement duration of each frequency point in the more frequency points, a measurement GAP with a longer duration can be used. Compared with the solution of configuring only one measurement GAP and completing the measurement of different measurement object sets within the one measurement GAP, it can avoid the degradation of data transmission performance and measurement performance caused by unreasonable GAP settings.

[0012] In one possible design, obtaining measurement GAPs corresponding to one or more measurement object sets also includes: when the measurement amount of the measurement object with the lowest priority among the priorities of one or more measurement objects in the Nth measurement object set is less than or equal to a first threshold, receiving the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, wherein the first threshold is used to determine whether the measurement amount of the measurement object with the lowest priority in the Nth measurement object set satisfies the requirement to start measurement of the Xth measurement object in one or more measurement objects, the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object, the priority of the Xth measurement object is lower than the lowest priority of the measurement objects in the Nth measurement object set, and X is a positive integer.

[0013] Based on this possible design, when the measurement amount of the measurement object with the lowest priority among the priorities of one or more measurement objects in the Nth measurement object set is less than or equal to the first threshold, it indicates that the measurement amount of the measurement object with the lowest priority does not meet its corresponding measurement reporting condition, that is, the terminal device fails to report the measurement amount. In order to avoid the terminal device from failing the radio link in the current cell due to delayed switching, the low-priority measurement object (that is, the Xth measurement object) can be added to the Nth measurement object set, thereby forming the N+1th measurement object set, so as to expand the measurement range and increase the probability of finding the target cell, thereby achieving timely and reasonable switching.

[0014] In one possible design, the communication method also includes: receiving indication information for indicating a first threshold.

[0015] Based on this possible design, when the measurement quantity of the lowest-priority measurement object among the priorities of one or more measurement objects in the Nth measurement object set is less than or equal to a first threshold, it indicates that the measurement quantity of the lowest-priority measurement object does not meet its corresponding measurement reporting condition. At this time, the measurement quantity of each measurement object in the Nth measurement object set is poor. If only the measurement objects in the Nth measurement object set are still measured, measurement quantity reporting may not be achieved. Therefore, the low-priority measurement object (i.e., the Xth measurement object) is also added to the Nth measurement object set to obtain the N+1th measurement object set, thereby expanding the measurement range and improving the probability of finding the target cell, thereby achieving timely and reasonable cell switching.

[0016] In one possible design, before receiving the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, the communication method further includes: sending indication information for instructing to start measurement of the Xth measurement object.

[0017] Based on this possible design, after the measurement object range is expanded (i.e., from measuring the Nth measurement object set to measuring the N+1th measurement object set), the terminal device needs to send an indication to the radio access network device to instruct it to start measuring the Xth measurement object, thereby enabling each measurement object in the N+1th measurement object set. The radio access network device also learns the measurement object set currently to be measured (i.e., the N+1th measurement object set) and indicates the N+1th measurement GAP corresponding to the N+1th measurement object set to the terminal device, ensuring that the terminal device can fully measure each measurement object in the N+1th measurement object set, thereby avoiding a degradation in measurement performance.

[0018] In one possible design, when a second threshold exists, the (N+1)th measurement object set includes the (N)th measurement object set and the (X)th measurement object. The second threshold is used to determine whether a measurement amount of the (X)th measurement object satisfies the requirement for initiating measurement of the (Y)th measurement object among one or more measurement objects. The priority of the (Y)th measurement object is lower than that of the (X)th measurement object, and Y is a positive integer.

[0019] In one possible design, when the second threshold does not exist and the third threshold exists, the N+1th measurement object set also includes the Yth measurement object among one or more measurement objects, the second threshold is used to determine whether the measurement amount of the Xth measurement object satisfies the requirement for initiating measurement of the Yth measurement object, and the third threshold is used to determine whether the measurement amount of the Yth measurement object satisfies the requirement for initiating measurement of the Zth measurement object among the one or more measurement objects. The priority of the Yth measurement object is lower than the priority of the Xth measurement object, and the priority of the Zth measurement object is lower than the priority of the Yth measurement object. X, Y, and Z are all positive integers.

[0020] In one possible design, the communication method also includes: receiving indication information for indicating a second threshold.

[0021] In one possible design, the communication method also includes: receiving indication information for indicating a third threshold.

[0022] Based on the above four possible designs, when the measurement quantity of the lowest-priority measurement object among the priorities of one or more measurement objects in the Nth measurement object set is less than or equal to the first threshold, it indicates that the measurement quantity of the lowest-priority measurement object does not meet its corresponding measurement reporting condition. At this time, the measurement quantity of each measurement object in the Nth measurement object set is poor, and therefore the measurement range needs to be expanded. Therefore, the terminal device can expand the measurement range (i.e., determine the measurement objects that need to be added to the Nth measurement object set) based on whether there is a threshold (such as the second threshold or the third threshold) for determining whether to start low-priority frequency point measurement. For example, when the second threshold exists, the Xth measurement object is added to the Nth measurement object set to form the N+1th measurement object set (in this case, the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object). When the second threshold does not exist and the third threshold exists, the Xth measurement object and the Yth measurement object are added to the measurement object set (in this case, the N+1th measurement object set includes the Nth measurement object set, the Xth measurement object, and the X+1th measurement object). Compared with the solution of measuring all measurement objects, measurement actions can be reduced and power consumption can be saved.

[0023] In one possible design, obtaining measurement GAPs corresponding to one or more measurement object sets respectively also includes: when the measurement amount of the Mth measurement object in the priority of one or more measurement objects in the Nth measurement object set is greater than or equal to a fourth threshold, receiving the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, wherein the fourth threshold is used to determine whether the measurement amount of the Mth measurement object in the Nth measurement object set satisfies the requirement of stopping the measurement of measurement objects whose priority is less than the priority of the Mth measurement object, the N+1th measurement object set includes measurement objects in the Nth measurement object set whose priority is greater than or equal to the priority of the Mth measurement object, and M is a positive integer.

[0024] In one possible design, before receiving the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, the communication method also includes: sending indication information for indicating to stop the measurement of the measurement object whose priority is less than the priority of the Mth measurement object.

[0025] Based on the above two possible designs, when the measurement amount of the Mth measurement object in the Nth measurement object set is greater than or equal to the fourth threshold, it indicates that the measurement amount of the Mth measurement object is good, that is, if the measurement objects with a priority greater than or equal to the priority of the Mth measurement object in the Nth measurement object set are measured at this time, the probability of the terminal device reporting the measurement is greater, so there is no need to measure the measurement objects with a priority less than the priority of the Mth measurement object, so the measurement range can be narrowed, that is, the N+1th measurement object set includes the measurement objects with a priority greater than or equal to the priority of the Mth measurement object in the Nth measurement object set. Compared with the solution of measuring all measurement objects, it can reduce measurement actions and save power consumption.

[0026] In one possible design, obtaining measurement GAPs corresponding to one or more measurement object sets includes: determining measurement GAPs corresponding to one or more measurement object sets from a first correspondence relationship, where the first correspondence relationship includes a correspondence between the measurement object set and the measurement GAP.

[0027] In one possible design, determining the measurement GAPs corresponding to one or more measurement object sets respectively from the first correspondence relationship includes: determining the measurement GAP corresponding to the Nth measurement object set in the one or more measurement object sets in the first correspondence relationship as the Nth measurement GAP; the communication method also includes: sending indication information indicating the Nth measurement GAP.

[0028] Based on this possible design, after determining the Nth measurement GAP, the terminal device needs to send indication information indicating the Nth measurement GAP to the radio access network device. Accordingly, after receiving the indication information, the radio access network device suspends data transmission between it and the terminal device within the Nth measurement GAP, thereby avoiding packet loss caused by the radio access network device transmitting data to the terminal device during the Nth measurement GAP and the terminal device being unable to receive the data within the Nth measurement GAP.

[0029] In one possible design, the first information also indicates a first corresponding relationship.

[0030] In one possible design, a first measurement object set in the one or more measurement object sets includes a measurement object with the highest priority among the one or more measurement objects.

[0031] In a second aspect, a communication method is provided. The method can be performed by a radio access network device, or by a component of the radio access network device, such as a processor, chip, or chip system of the radio access network device, or by a logic module or software capable of implementing all or part of the functions of the radio access network device. The method includes: sending first information indicating the priority of one or more measurement objects; sending measurement gaps (GAPs) corresponding to one or more measurement object sets, the one or more measurement object sets being determined based on the priority of the one or more measurement objects, and the measurement GAPs being used to measure the measurement object sets corresponding to the measurement GAPs.

[0032] Based on this solution, the radio access network device sends first information indicating the priority of one or more measurement objects, and measurement GAPs corresponding to one or more measurement object sets, to the terminal device; this enables the terminal device to measure a measurement object set within the measurement GAP corresponding to the measurement object set, i.e., the terminal device can measure different measurement object sets in different GAPs. In other words, different measurement GAPs can be used depending on the measurement object set to ensure that the frequency indicated by each measurement object in the measurement object set can be fully measured. For example, to adapt the measurement duration of each measurement object in the measurement object set, a shorter measurement GAP may be used when there are fewer measurement objects in the measurement object set, while a longer measurement GAP may be used when there are more measurement objects in the measurement object set. Compared to a solution that configures only one measurement GAP and completes measurements of different measurement object sets within the one measurement GAP, this solution can avoid, on the one hand, transmission performance degradation caused by excessively long data transmission pauses, and, on the other hand, measurement performance degradation caused by insufficient measurement duration.

[0033] In one possible design, sending measurement GAPs corresponding to one or more measurement object sets includes: sending the Nth measurement GAP corresponding to the Nth measurement object set in the one or more measurement object sets, where N is a positive integer.

[0034] In one possible design, sending measurement GAPs corresponding to one or more measurement object sets also includes: receiving indication information used to instruct the initiation of measurement of the Xth measurement object in one or more measurement object sets, where the priority of the Xth measurement object is lower than the lowest priority of the measurement objects in the Nth measurement object set, and X is a positive integer; sending the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, where the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object.

[0035] In one possible design, the communication method further includes: sending indication information for indicating a first threshold, the first threshold being used to determine whether the measurement quantity with the lowest priority in the Nth measurement object set meets the requirements for initiating measurement of the Xth measurement object in one or more measurement objects.

[0036] In one possible design, when the second threshold exists, the (N+1)th measurement object set includes the (N)th measurement object set and the (X)th measurement object. The second threshold is used to determine whether a measurement amount of the (X)th measurement object satisfies the requirement for initiating measurement of the (Y)th measurement object among one or more measurement objects. The priority of the (Y)th measurement object is lower than that of the (X)th measurement object, and Y is a positive integer.

[0037] In one possible design, when the second threshold does not exist and the third threshold exists, the N+1th measurement object set also includes the Yth measurement object among one or more measurement objects, the second threshold is used to determine whether the measurement amount of the Xth measurement object satisfies the requirement for initiating measurement of the Yth measurement object, and the third threshold is used to determine whether the measurement amount of the Yth measurement object satisfies the requirement for initiating measurement of the Zth measurement object among the one or more measurement objects. The priority of the Yth measurement object is lower than that of the Xth measurement object, and the priority of the Zth measurement object is lower than that of the Yth measurement object. X, Y, and Z are all positive integers.

[0038] In one possible design, the communication method also includes: sending indication information for indicating a second threshold.

[0039] In one possible design, the communication method also includes: sending indication information for indicating a third threshold.

[0040] In one possible design, sending measurement GAPs corresponding to one or more measurement object sets also includes: receiving indication information for instructing to stop measurement of measurement objects whose priority is less than that of the Mth measurement object in the Nth measurement object set, where M is a positive integer; and sending the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets, where the N+1th measurement object set includes measurement objects whose priority is greater than or equal to that of the Mth measurement object in the Nth measurement object set.

[0041] In one possible design, the communication method further includes: sending indication information for indicating a fourth threshold, the fourth threshold being used to determine whether the measurement amount of the Mth measurement object in the Nth measurement object set satisfies the requirement of stopping measurement objects whose priority is less than the priority of the Mth measurement object.

[0042] In a possible design, the first information further indicates a first correspondence, where the first correspondence includes a correspondence between a measurement object set and a measurement GAP.

[0043] In one possible design, the communication method also includes: receiving indication information for indicating the Nth measurement GAP, the Nth measurement GAP being the measurement GAP corresponding to the Nth measurement object set in the first corresponding relationship, and the Nth measurement GAP being used for measurement of the Nth measurement object set.

[0044] In one possible design, a first measurement object set in the one or more measurement object sets includes a measurement object with the highest priority among the one or more measurement objects.

[0077] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first given as follows.

[0078] 1. Measurement configuration (measconfig) information:

[0079] The measurement configuration information is used in the measurement reporting process during cell handover; the measurement configuration information is carried in radio resource control (RRC) reconfiguration information.

[0080] Exemplarily, the measurement configuration information may include the content shown in Table 1 below:

[0081] Table 1

[0082] Each measurement configuration has a unique identifier (measId), and each measurement object has a unique ID (measObjectId). To ensure accurate and complete measurement of the SSB beam in each cell, when configuring the measurement object, the base station not only indicates the time-frequency position and subcarrier spacing of the reference signal, but also the SMTC (the timing position and duration for initiating reference signal measurement). The SMTC configuration effectively indicates the time window in which the UE searches for reference signals, which can be SSBs or CSI-RS. Each reporting configuration has a unique identifier (reportConfigId). The reporting configuration (also known as the measurement reporting condition configuration) can be event-triggered or periodic. Event-triggered reporting configuration includes various event categories and thresholds, the duration for meeting the trigger condition, the measurement quantity to be reported, and the reference signal type. Definitions for various events include A1, A2, A3, A4, A5, A6, B1, and B2 events. Periodic reporting configuration includes the reporting period, reference signal type, the measurement quantity to be reported, and a list of available whitelisted cells.

[0083] The measurement GAP is a time interval specifically used for measurement agreed upon between the network and the UE. During the measurement GAP, the terminal device and the primary serving cell suspend uplink and downlink data transmission. After the measurement GAP ends, the UE resumes sending and receiving data. An exemplary measurement GAP configuration (measgapconfig) field may include the fields shown in Table 2 below:

[0084] Table 2

[0085] When the terminal device needs to measure an inter-frequency point or an inter-system frequency point, the base station determines that a measurement GAP is configured for the terminal device.

[0086] The 3rd Generation Partnership Project (3GPP) protocol TS 38.133 defines 24 GAP patterns, each corresponding to a different MGL and MGRP. To reduce the overhead of measuring GAPs, the GAP pattern can be adaptively selected based on the terminal device's capabilities and / or SMTC configuration, and then sent to the terminal device via measurement configuration information.

[0087] Optionally, the effective measurement duration in the measurement GAP is greater than or equal to the duration of SMTC to ensure that the heterofrequency point can be fully measured. The effective measurement duration is the difference between the measurement GAP and the switching time of the first and last frequency points. For example, as shown in Figure 1, the duration of SMTC is 2 milliseconds (MS), and the effective measurement time of the measurement GAP can completely cover the duration of SMTC. The duration of the frequency switching is 1ms. At this time, the time interval length of the measurement GAP must be greater than or equal to 3ms. The SMTC configuration is based on the SSB frequency point. When the number of frequency points increases, it is necessary to ensure that the effective measurement duration of the measurement GAP can cover the duration of SMTC corresponding to multiple frequency points.

[0088] 2. Cell handover:

[0089] For example, in a fifth generation (5G) or new radio (NR) system, the cell handover process may include steps S201-S209 as shown in FIG2 :

[0090] Step S201: The source base station (also referred to as the serving base station before handover) of the terminal device may send measurement configuration information to the terminal device. Correspondingly, the terminal device receives the measurement configuration information from the source base station.

[0091] Step S202: The terminal device measures the measurement object according to the measurement configuration information.

[0092] Optionally, if the measurement result of a measurement object measured by the terminal device within a certain time period meets the measurement reporting conditions, the terminal device reports the measurement report.

[0093] The measurement result is obtained by measuring at layer 1 (eg, the physical (PHY) layer) and filtering at layer 3 (eg, the RRC layer).

[0094] Step S203: The terminal device sends a measurement report to the source base station. Correspondingly, the source base station receives the measurement report from the terminal device.

[0095] Exemplarily, the measurement quantity includes a measurement ID, a measurement quantity of a primary serving cell, and a measurement quantity of a neighboring cell of the primary serving cell, wherein the measurement quantity of the cell may include: a physical cell identity (PCI), a cell reference signal measurement result, a beam reference signal measurement result, and the like.

[0096] Step S204: After receiving the measurement report, the source base station determines the target cell based on the measurement report.

[0097] For example, the source base station evaluates the measurement results in the measurement report and then determines the target cell.

[0098] Step S205: The source base station sends a handover request to the target base station to which the target cell belongs. Correspondingly, the target base station receives the handover request from the source base station.

[0099] Exemplarily, the handover request includes information required for handover, such as the ID of the target cell.

[0100] Step S206: The target base station performs admission control.

[0101] Optionally, admission control can be understood as determining whether the terminal device is supported to access the target base station.

[0102] When the terminal device is supported to access the target base station, step S207 is executed:

[0103] S207: The target base station sends a handover confirmation message to the source base station. Correspondingly, the source base station receives the handover confirmation message from the target base station.

[0104] Exemplarily, the handover confirmation information includes configuration information related to the target cell (such as the ID of the target cell, etc.).

[0105] Step S208: The source base station sends an RRC reconfiguration message (handover command) to the terminal device. Correspondingly, the terminal device receives the RRC reconfiguration message from the source base station.

[0106] Step S209: The terminal device performs switching according to the switching command.

[0107] Exemplarily, the terminal device may perform RRC reconfiguration based on the RRC reconfiguration information. After the RRC reconfiguration is completed, the terminal device sends a message indicating that the RRC reconfiguration is successful to the target base station. Accordingly, the target base station receives the message indicating that the RRC reconfiguration is successful from the terminal device. At this point, the handover of the terminal device to the radio access network (RAN) side can be considered successful.

[0108] Optionally, the switching in this application generally refers to the switching of base station control and terminal device control in the RRC connection state, cell change, etc.

[0109] In a networking scenario with multiple overlapping frequencies, different service requirements have different target base stations. For example, for data services, higher frequencies can ensure data transmission performance. Therefore, the requirement for data services is to prioritize cells with higher frequencies as target cells. For continuous coverage services, lower frequencies can ensure the stability of continuous coverage. Therefore, the requirement for continuous coverage services is to prioritize cells with lower frequencies as target cells.

[0110] However, in the cell handover process shown in Figure 2, the terminal device determines whether the reporting conditions are met based on the cell's signal quality, so the source base station determines the target base station as the base station in the neighboring cell with the best signal quality. In other words, the cell handover process shown in Figure 2 does not take different service requirements into account, resulting in the target cell determined by the cell handover process in Figure 2 not meeting the service requirements of the terminal device.

[0111] Based on this, an embodiment of the present application provides a communication method, in which a terminal device can measure a measurement object set within a measurement GAP corresponding to the measurement object set, that is, the terminal device can measure different measurement object sets in different GAPs, that is, different measurement GAPs can be used according to different measurement object sets to ensure that the frequency indicated by each measurement object in the measurement object set can be fully measured. For example, in order to adapt the measurement duration of each measurement object in the measurement object set, a measurement GAP with a shorter duration may be used when there are fewer measurement objects in the measurement object set, and a measurement GAP with a longer duration may be used when there are more measurement objects in the measurement object set. Compared with the solution of configuring only one measurement GAP and completing the measurement of different measurement object sets within the one measurement GAP, on the one hand, it can avoid the degradation of transmission performance caused by too long a data transmission suspension time, and on the other hand, it can avoid the degradation of measurement performance caused by insufficient measurement duration.

[0112] In addition, since one or more measurement object sets are determined based on the priority of one or more measurement objects, the terminal device can select an appropriate measurement object set for measurement based on the priority. For example, a measurement object set including the highest priority can be selected for measurement. It can be understood that in different scenarios, the priority of the same measurement object can be different, so that the one or more measurement object sets determined based on the priority in different scenarios are also different. For example, the priority of one or more measurement objects can be set according to the business requirements of the terminal device, such as setting the priority of the measurement object that best meets the business requirements to the highest priority, and setting the priority of the measurement object that relatively meets the business requirements to the second highest priority, etc. Therefore, when selecting a measurement object set, the terminal device can give priority to selecting the measurement object set that best meets the business requirements including the highest priority for measurement, thereby making the target cell used to perform the handover meet the business requirements as much as possible.

[0113] The technical solution provided in this application can be used for various communication systems, which may be 3GPP communication systems, for example, fourth generation (4G) long term evolution (LTE) systems, fifth generation (5G) NR systems, future evolution systems (such as sixth generation (6G) systems), vehicle to everything (V2X) systems, LTE and NR hybrid networking systems, or device to device (D2D) systems, machine to machine (M2M) communication systems, Internet of Things (IoT) cloud radio access networks (CRAN), open access networks (open RAN, O-RAN or ORAN), wireless fidelity (WIFI) systems, and other next generation communication systems. Alternatively, the communication system may be a communication system obtained by integrating at least two of the above systems.

[0116] Optionally, a terminal device may refer to a user-side device with wireless transceiver functions, which can send signals to a network device or receive signals from a network device. A terminal device may also be referred to as user equipment (UE), terminal, access terminal, user unit, user station, mobile station (MS), remote station, remote terminal, mobile terminal (MT), user terminal, wireless communication device, user agent or user device, etc. The terminal can be widely used in various scenarios, for example, it can be a wireless terminal in IoT, V2X, D2D, M2M, MTC, 5G network, or future evolved PLMN. The terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0117] Exemplarily, the terminal device may be a drone, a helicopter, a robotic arm, an IoT device (e.g., a sensor, an electricity meter, a water meter, etc.), a V2X device, a station (ST) in a wireless local area network (WLAN), a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device (also referred to as a wearable smart device), a tablet computer or a computer with wireless transceiver function, 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 care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a smart home, or a similar device. The present invention relates to wireless terminals in smart homes, wireless devices in smart home control systems (SCS), wireless devices in smart office automation (OA), vehicle-mounted terminals, vehicles with vehicle-to-vehicle (V2V) communication capabilities, intelligent connected vehicles, drones with UAV to UAV (U2U) communication capabilities, etc. The terminal can be mobile or fixed, and this application does not specifically limit this.

[0118] Optionally, a radio access network device is a device that connects a terminal device to a wireless network, or may also be referred to as a RAN node, or a RAN entity, or an access node, etc. The radio access network device may be an evolutionary Node B (eNB or eNodeB) in an LTE or evolved LTE system (LTE-Advanced, LTE-A), such as a traditional macro base station eNB and a micro base station eNB in ​​a heterogeneous network scenario; or it may be a next generation node B (gNodeB or gNB) in a 5G system; or it may be a next generation base station in a 6G system; or it may be a transmission reception point (TRP); or it may be a base station in a future evolved public land mobile network (PLMN); or it may be a broadband network gateway (BNG), an aggregation switch or a non-3GPP access device; or it may be a wireless controller in a cloud radio access network (CRAN); or it may be an access node (access point) in a WiFi system. point, AP); or it can be a wireless relay node or a wireless backhaul node; or it can be a device that implements the base station function in IoT, a device that implements the base station function in V2X, a device that implements the base station function in D2D, or a device that implements the base station function in M2M, and the embodiments of the present application do not make specific limitations on this.

[0119] For example, the base station in the embodiments of the present application may include various forms of base stations, such as macro base stations, micro base stations (also known as small base stations), indoor base stations, relay stations, access points, donor nodes, etc., or may be a wireless controller in a CRAN scenario. The embodiments of the present application are not specifically limited to this.

[0120] Optionally, the wireless access network device may be a server, a wearable device, a vehicle, or an onboard device. For example, in V2X technology, the access network device may be a road side unit (RSU). This embodiment of the present application does not specifically limit this.

[0121] Optionally, the roles between the wireless access network device and the terminal device can be relative. For example, in FIG3 , terminal 120i and terminal 120j are configured as a wireless access network device relative to terminal 120j because terminal 120j needs to access wireless access network device 110a through terminal 120i. However, relative to wireless access network device 110a, terminal 120i is a terminal device. That is, wireless access network device 110a and terminal 120i communicate via a wireless air interface protocol. Alternatively, wireless access network device 110a and terminal 120i can also communicate via an interface protocol between wireless access network devices. In this case, terminal 120i also functions as a wireless access network device relative to wireless access network device 110a. Optionally, the radio access network device and the terminal device, the radio access network device and the radio access network device, or the terminal device and the terminal device can communicate through the authorized spectrum, or can communicate through the unlicensed spectrum, or can communicate through the authorized spectrum and the unlicensed spectrum at the same time. Optionally, the radio access network device and the terminal device, the radio access network device and the radio access network device, or the terminal device and the terminal device can communicate through the spectrum below 6 gigahertz (GHz), or can communicate through the spectrum above 6 GHz, or can use the spectrum below 6 GHz and the spectrum above 6 GHz at the same time. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0122] Optionally, in a specific implementation, a radio access network device may refer to a module or unit that performs some of the functions of a base station. For example, a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). Alternatively, it may refer to an access network device or a module of an access network device in an open ORAN system.

[0123] Figure 4 shows the modules of the access network equipment of the ORAN system in an embodiment of the present application. The radio access network equipment includes: CU, DU, and RU. The CU includes the CU-UP and CU-CP. The radio access network equipment communicates with the terminal device through the RU.

[0124] Optionally, the CU and DU can be set up separately, or they can be included in the same network element (such as the baseband unit (BBU)). The CU node and the DU node split the protocol layer of the gNB, and the functions of some protocol layers are centrally controlled by the CU, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0125] In some embodiments, the CU and DU can be divided according to the protocol layers of the wireless network: for example, the functions of the packet data convergence protocol (PDCP) layer and the above protocol layers (such as the radio resource control (RRC) layer and the service data adaptation protocol (SDAP) layer, etc.) are set in the CU, and the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC) layer, the media access control (MAC) layer, or the physical (PHY) layer, etc.) are set in the DU; for another example, the functions of the protocol layers above the PDCP layer are set in the CU, and the functions of the protocol layers above the PDCP layer are set in the DU, without restriction.

[0126] Refer to (a) in Figure 5, which is the functional setting of CU and DU in an embodiment of the present application. In (a) in Figure 5, the base station consists of CU-CP, CU-UP and a DU. CU-CP is used to implement the functions of the RRC layer and the control plane (PDCP control, PDCP-C) functions of the PDCP layer, CU-UP is used to implement the functions of the SDAP layer and the user plane (PDCP users, PDCP-U) functions of the PDCP layer, and DU is used to implement the functions of the RLC layer, the MAC layer, and the PHY layer. Among them, CU-CP and CU-UP are connected through the E1 interface, CU-CP and DU are connected through the F1-C interface, and CU-UP and DU are connected through the F1-U interface.

[0127] Refer to Figure 5(b), which shows the functional settings of the CU and DU in an embodiment of the present application. In Figure 5(b), the base station consists of a CU and two DUs. The CU is used to implement the functions of the RRC layer, the SDAP layer, and the PDCP layer, and the DU is used to implement the functions of the RLC layer, the MAC layer, and the PHY layer. The CU and the DU are connected via the F1 interface.

[0128] The above division of the processing functions of CU and DU according to the protocol layer is only an example, and they can also be divided in other ways. For example, the CU or DU can be divided into functions with more protocol layers, and the CU or DU can be divided into partial processing functions with protocol layers. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements, such as division by delay, and the functions whose processing time needs to meet the delay requirements are set in the DU, and the functions that do not need to meet the delay requirements are set in the CU.

[0129] In some embodiments, the RU may be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0130] In some embodiments, when the radio access network device is an access network device or a module of an access network device in an open ORAN system, in the ORAN system, the CU may also be referred to as an open (O)-CU, the DU may also be referred to as an O-DU, the CU-CP may also be referred to as an O-CU-CP, the CU-UP may also be referred to as an O-CU-UP, and the RU may also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU, and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0131] For example, the network elements and their functions included in the ORAN system may be shown in Table 3 below:

[0133] The measurement method provided in the embodiments of the present application will be described below in conjunction with the accompanying drawings. It will be appreciated that in the embodiments of the present application, the wireless access network device or the terminal device may perform some or all of the steps in the embodiments of the present application. These steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations. In addition, the various steps may be performed in a different order than those presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application need to be performed.

[0134] It should be noted that the message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are only examples. Other names may be used in specific implementations, and the embodiments of the present application do not specifically limit this.

[0135] 6 , which shows a measurement method provided in an embodiment of the present application, the measurement method includes the following steps:

[0136] S601: A wireless access network device sends first information to a terminal device. In response, the terminal device receives the first information from the wireless access network device. The first information indicates the priority of one or more measurement objects. Alternatively, the first information indicates the priority of one or more measurement objects corresponding to the indicated frequency points.

[0137] Optionally, the first information may be carried in an RRC reconfiguration message; further, the first information may be carried in measurement configuration information carried in the RRC reconfiguration message.

[0138] Exemplarily, the first information may indicate the priorities of multiple measurement objects at one time; or, the first information may also indicate the priority of one measurement object, and the first information may be sent multiple times to indicate the priorities of multiple measurement objects. For example, the wireless access network device may indicate the priority of a measurement object to the terminal device, and upon receiving the indication information from the terminal device indicating the start of the measurement object of the next priority, it may indicate the measurement object of the next priority to the terminal device; or the wireless access network device may also indicate the priority of one or more measurement objects by other methods other than the above, without limitation. The one or more measurement objects include at least one of a measurement object indicating the frequency of the serving cell, a measurement object indicating an inter-frequency frequency, or a measurement object indicating an inter-system frequency.

[0139] Exemplarily, the priority of the measurement object can also be referred to as the priority of the frequency indicated by the measurement object, the priority of the frequency, the measurement order of the measurement object (or frequency), the order of the measurement object (or frequency), or other names may exist, which are not limited in the embodiments of the present application.

[0140] Optionally, the correspondence between multiple frequency points and priorities may include the following two examples:

[0141] As an example, one measurement object corresponds to one priority. For example, taking three measurement objects (measurement object #1 to measurement object #3) as an example, the priority of measurement object #1 may be the highest priority, the priority of measurement object #2 may be the second highest priority, and the priority of measurement object #3 may be the lowest priority. In other words, measurement objects #1 to measurement objects #3 correspond to a total of three priorities, and the three priorities decrease in sequence.

[0142] As another example, multiple measurement objects correspond to one priority. For example, taking three measurement objects (measurement object #1 to measurement object #3) as an example, the priority of measurement object #1 can be the highest priority, and measurement objects #2 and measurement objects #3 have the same priority, both of which are the lowest priority. In other words, measurement objects #1 to measurement objects #3 correspond to a total of two priorities, and the two priorities decrease in sequence.

[0143] Optionally, in the configuration of the priorities of multiple measurement objects, the priority of the measurement object is determined according to the business requirements of the terminal device based on the degree of compliance of each measurement object in the multiple measurement object points with the business requirements. For example, the priority of the measurement object that best meets the business requirements can be set to the highest priority, the priority of the measurement object that relatively meets the business requirements can be set to the second highest priority, and the priority of the measurement object that least meets the business requirements can be set to the lowest priority.

[0144] For example, the priority of the same measurement object may be different under different requirements of the terminal device. Taking three measurement objects (measurement object #1 to measurement object #3), where the frequency points indicated by measurement objects #1 to measurement object #3 decrease in sequence, as an example, when data transmission performance is required, the priority of measurement objects #1 to measurement object #3 decreases in sequence; when signal stability (i.e., coverage quality) is required, the priority of measurement objects #1 to measurement object #3 increases in sequence.

[0145] S602. The terminal device obtains measurement GAPs corresponding to one or more measurement object sets, where the one or more measurement object sets are determined based on the priority of one or more measurement objects, and the measurement GAP is used to measure the measurement object set corresponding to the measurement GAP.

[0146] Exemplarily, in the embodiment of the present application, the measurement object indicates a frequency point, and therefore measuring the measurement object set corresponding to the measurement GAP refers to measuring the frequency points respectively indicated by each measurement object in the measurement object set included in the measurement object set, that is, measuring the cell on the frequency point respectively indicated by each measurement object in the measurement object set included in the measurement object set.

[0147] Optionally, the measured GAP can be determined by measuring parameters such as the GAP length (MGL), the offset of the GAP repetition period (MGRP), etc. Specifically, MGL and MGRP can refer to the relevant description of Table 2 above, and the present embodiment will not be repeated here.

[0148] An embodiment of the present application provides a communication method, in which a terminal device is capable of measuring a measurement object set within a measurement GAP corresponding to the measurement object set, that is, the terminal device is capable of measuring different measurement object sets in different GAPs, that is, different measurement GAPs can be used according to different measurement object sets to ensure that the frequency indicated by each measurement object in the measurement object set can be fully measured. For example, in order to adapt the measurement duration of each measurement object in the measurement object set, a measurement GAP with a shorter duration may be used when there are fewer measurement objects in the measurement object set, and a measurement GAP with a longer duration may be used when there are more measurement objects in the measurement object set. Compared with the solution of configuring only one measurement GAP and completing the measurement of different measurement object sets within the one measurement GAP, on the one hand, it can avoid the degradation of transmission performance caused by too long a data transmission suspension time, and on the other hand, it can avoid the degradation of measurement performance caused by insufficient measurement duration.

[0149] In addition, since one or more measurement object sets are determined based on the priority of one or more measurement objects, the terminal device can select an appropriate measurement object set for measurement based on the priority. For example, a measurement object set including the highest priority can be selected for measurement. It can be understood that in different scenarios, the priority of the same measurement object can be different, so that the one or more measurement object sets determined based on the priority in different scenarios are also different. For example, the priority of one or more measurement objects can be set according to the business requirements of the terminal device, such as setting the priority of the measurement object that best meets the business requirements to the highest priority, and setting the priority of the measurement object that relatively meets the business requirements to the second highest priority, etc. Therefore, when selecting a measurement object set, the terminal device can give priority to selecting the measurement object set that best meets the business requirements including the highest priority for measurement, thereby making the target cell used to perform the handover meet the business requirements as much as possible.

[0150] The above is an overall description of the communication method provided in the embodiment of the present application. The following is a detailed introduction to obtaining the measurement GAP corresponding to one or more measurement object sets mentioned in the above embodiment. For example, the terminal device can obtain the measurement GAP corresponding to one or more measurement object sets based on the following two possible implementation methods:

[0151] In a first possible implementation, the terminal device receives an Nth measurement GAP from the radio access network device. The Nth measurement GAP is a measurement GAP corresponding to the Nth measurement object set in one or more measurement object sets. That is, as shown in FIG7 (FIG7(a) or FIG7(b)), the above step S602 may include step S602A:

[0152] S602A: The radio access network device sends the Nth measurement GAP corresponding to the Nth measurement object set in one or more measurement object sets to the terminal device. Correspondingly, the terminal device receives the Nth measurement GAP from the radio access network device, where N is a positive integer.

[0153] Exemplarily, after obtaining the Nth measurement object set, the terminal device may measure the Nth measurement object set within the Nth measurement GAP. Exemplarily, when N is 1, the first measurement GAP may be carried in the first information, that is, the first information may also indicate the first measurement GAP.

[0154] Optionally, after step S602A, as shown in FIG7 , the communication method may further include step S603A:

[0155] S603A: Determine whether there is a measurement quantity that satisfies the measurement reporting condition corresponding to each measurement object in the Nth measurement object set, wherein the measurement objects correspond to the measurement reporting conditions in a one-to-one manner and the measurement objects correspond to the measurement quantities in a one-to-one manner.

[0156] Exemplarily, the measurement reporting conditions corresponding to each measurement object may be the same or different. For ease of description, the measurement reporting conditions corresponding to each measurement object are referred to as measurement reporting conditions. For example, if the measurement quantities of the measurement objects in the Nth measurement object set do not satisfy the measurement reporting conditions, it can be understood that the measurement quantities of each measurement object in the measurement objects in the Nth measurement object set do not satisfy their respective corresponding measurement reporting conditions.

[0157] Optionally, if there is a measurement amount that meets the measurement reporting condition among the measurement amounts corresponding to the measurement objects in the Nth measurement object set, as shown in (a) of FIG7 , the communication method may further include step S604A:

[0158] S604A: The terminal device reports the measurement quantity that meets the measurement reporting condition, so that the radio access network device can select a target cell from cells on the frequency indicated by the measurement object corresponding to the measurement quantity.

[0159] Exemplarily, the measurement quantity of the measurement object may include a measurement result of at least one cell at a frequency point indicated by the measurement object, such as signal quality of at least one cell.

[0160] Optionally, if there is no measurement quantity that meets the measurement reporting conditions among the measurement quantities corresponding to the measurement objects in the Nth measurement object set, as shown in (b) in Figure 7, the communication method may also include step S604B: the terminal device determines the N+1th measurement object set.

[0161] Exemplarily, the N+1th measurement object set may be implemented based on the following three situations:

[0162] Case 1: the number of measurement objects included in the N+1th measurement object set is greater than the number of measurement objects included in the Nth measurement object set.

[0163] Optionally, the terminal device may determine the N+1th measurement object set based on a first threshold value. The first threshold value is used to determine whether the measurement amount of the lowest-priority measurement object in the Nth measurement object set satisfies the requirement for initiating measurement of the Xth measurement object among one or more measurement objects, where the priority of the Xth measurement object is lower than the lowest priority of the measurement objects in the Nth measurement object set, and X is a positive integer.

[0164] Optionally, the first threshold value may be a threshold value. Alternatively, it may be a threshold range. In this case, if the measurement value of the lowest-priority measurement object is less than or equal to the first threshold value, it indicates that the measurement value of the lowest-priority measurement object is less than or equal to the minimum value in the first threshold value (i.e., the threshold range). Exemplarily, the first threshold value may also be referred to as a low-priority measurement start threshold corresponding to the lowest-priority measurement object, or other names may exist without limitation.

[0165] Optionally, the correspondence between the priority of the measurement object and the low-priority measurement start threshold may include the following two implementations:

[0166] As a possible implementation, a low-priority measurement start threshold may be configured for each measurement object corresponding to each priority level of the multiple measurement objects.

[0167] For example, taking the priorities (priority #1 to priority #3) corresponding to three measurement objects as an example, the radio access network device configures low-priority measurement start threshold #1 for priority #1, low-priority measurement start threshold #2 for priority #2, and low-priority measurement start threshold #3 for priority #3. In this case, if the lowest priority in the Nth measurement object set is priority #2, low-priority measurement start threshold #2 is the first threshold.

[0168] As another possible implementation, each of some of the priority levels of the multiple measurement objects corresponds to a low-priority measurement start threshold. In other words, the radio access network device may configure a low-priority measurement start threshold for each of some of the priority levels of the multiple measurement objects.

[0169] For example, taking the priorities of three measurement objects (priority #1 to priority #3) as an example, the radio access network device configures low-priority measurement start threshold #1 for priority #1, does not configure a low-priority measurement start threshold for priority #2, and configures low-priority measurement start threshold #3 for priority #3. In this case, if the lowest priority in the Nth measurement object set is priority #1, low-priority measurement start threshold #1 is the first threshold.

[0170] Exemplarily, for a priority level for which a low-priority measurement start threshold is not configured among the priorities of multiple measurement objects, it can be considered that the measurement object corresponding to the priority level does not have a low-priority measurement start threshold. For example, when the wireless access network device in the above example does not configure a low-priority measurement start threshold for priority #2, it can be considered that the measurement object corresponding to priority #2 does not have a low-priority measurement start threshold, and when the terminal device evaluates that the measurement amount of low-priority #1 meets the low-priority start threshold #1 corresponding to priority #1, the terminal device determines to start the measurement object of priority #2 and the measurement object of priority #3.

[0171] Optionally, before step S604B, the radio access network device may send indication information for indicating the first threshold to the terminal device, and correspondingly, the terminal device receives the indication information for indicating the first threshold from the radio access network device.

[0172] Optionally, the indication information for indicating the first threshold value may be carried in an RRC reconfiguration message; further, the indication information for indicating the first threshold value may be carried in measurement configuration information carried by the RRC reconfiguration message. The indication information for indicating the first threshold value and the first information may be sent to the terminal device via the same RRC reconfiguration message or via different RRC reconfiguration messages. Alternatively, the first information may include indication information for indicating the first threshold value, that is, the first information indicates the priority and the first threshold value of one or more measurement objects.

[0173] Exemplarily, the indication information for indicating the first threshold is carried in the RRC reconfiguration information, which can be understood as follows: the first threshold is configured by the radio access network device for the terminal device through RRC signaling. Further, the first threshold is configured by the radio access network device for the lowest-priority measurement object among the Nth measurement object, and is used by the terminal device to evaluate whether the measurement amount of the lowest-priority measurement object is less than or equal to the first threshold.

[0174] Optionally, when the value of N is 1, the Nth measurement object set is the first measurement object set, and the first measurement object set includes the measurement object with the highest priority among one or more measurement objects (for the convenience of description, the measurement object with the highest priority is referred to as the first measurement object below). Furthermore, at this time, the first threshold is configured by the wireless access network device for the first measurement object, and is used to evaluate whether the measurement amount of the first measurement object is less than or equal to the first threshold. When the value of N is not 1, the Nth measurement object set includes measurement objects with a priority greater than or equal to the Qth measurement object among one or more measurement objects, that is, at this time, the measurement object with the lowest priority in the Nth measurement object set is the Qth measurement object.

[0175] Optionally, when the first threshold exists, or when the first threshold exists and the measurement amount of the measurement object with the lowest priority in the Nth measurement object set is greater than the first threshold, the N+1th measurement object set is determined. In this case, the N+1th measurement object set includes the Xth measurement object and the Nth measurement object set.

[0176] Exemplarily, taking the case where the priorities of measurement objects #1 to #3 decrease in sequence, and the Nth measurement object set includes measurement object #1 and measurement object #2, and the Xth measurement object is measurement object #3, at this time, the first threshold is used to determine whether the measurement amount of measurement object #2 starts the measurement of measurement object #3. Therefore, when there is no measurement amount that meets the measurement reporting condition in the Nth measurement object set, the terminal device can add measurement object #3 to the Nth measurement object set to obtain the N+1th measurement object set. Alternatively, the terminal device determines whether the measurement amount of measurement object #2 is less than or equal to the first threshold, and when the measurement amount of measurement object #2 is less than or equal to the first threshold, adds measurement object #3 to the Nth measurement object set to obtain the N+1th measurement object set. In the above example, the N+1th measurement object set includes measurement objects #1 to #3.

[0177] Optionally, in this optional solution, as shown in (a) of FIG8 , the communication method may further include step S602B: that is, step S602 may further include step S602B:

[0178] S602B. The radio access network device sends the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets to the terminal device. Correspondingly, the terminal device receives the N+1th measurement GAP from the radio access network device. That is, when the first threshold exists, or when the first threshold exists and the measurement amount of the lowest-priority measurement object in the Nth measurement object set is greater than the first threshold, the terminal device receives the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets.

[0179] Optionally, before step S602B, as shown in (a) of FIG8 , the communication method may further include step S605:

[0180] S605. The terminal device sends instruction information to the radio access network device for instructing the initiation of measurement of the Xth measurement object. Accordingly, the radio access network device receives the instruction information from the terminal device for instructing the initiation of measurement of the Xth measurement object. Thus, the radio access network device can perform step S602B in (a) of FIG8 based on the instruction information. That is, step S602B in (a) of FIG8 is triggered based on the instruction information for instructing the initiation of measurement of the Xth measurement object.

[0181] Optionally, the terminal device may measure the N+1th measurement object set within the N+1th measurement object set. Exemplarily, the implementation of the terminal device measuring the N+1th measurement object set within the N+1th measurement object set is similar to the implementation of measuring the Nth measurement object set within the Nth measurement object set. For details, reference may be made to the relevant description of the implementation of measuring the Nth measurement object set within the Nth measurement object set, which is not repeated here.

[0182] Based on this optional solution, the terminal device measures the Nth measurement object set in the Nth measurement GAP, and measures the N+1th measurement object set in the N+1th measurement GAP. That is, the terminal device can measure different measurement object sets in different measurement GAPs. In other words, different measurement GAPs can be used according to different measurement object sets. For example, when there are fewer measurement objects, a measurement GAP with a shorter duration may be used, and when there are more measurement objects, a measurement GAP with a longer duration may be used. Compared with the solution of configuring only one measurement GAP and completing the measurement of different measurement object sets within the one measurement GAP, on the one hand, it can avoid the degradation of transmission performance caused by too long a data transmission suspension time, and on the other hand, it can avoid the degradation of measurement performance.

[0183] Based on this first scenario, if the measurement value of the lowest-priority measurement object in the Nth measurement object set does not meet the measurement reporting conditions and is less than or equal to the first threshold, it indicates that the measurement value of the measurement object is poor, and therefore the measurement range needs to be expanded. This increases the probability of measurement value reporting and prevents the terminal device from failing the radio link in the current cell due to delayed handover.

[0184] Therefore, in the process of expanding the measurement range (i.e., adding measurement objects to the Nth measurement object set), according to the relationship between the priority of one or more measurement objects and the low-priority measurement start threshold, it can be seen that there may be a situation where a certain priority is not configured with a low-priority measurement start threshold. The terminal device does not need to evaluate the measurement amount of the priority, and it determines to start measurement of the measurement object with a priority lower than that. On the contrary, the terminal device can expand the measurement range according to the low-priority measurement start threshold. For example, the terminal device can determine the first priority (which can be called priority A) configured with a low-priority measurement start threshold among the priorities lower than the highest priority according to the order of priority from high to low, and add the measurement objects (or frequency points) corresponding to the priorities greater than or equal to priority A among the multiple measurement objects to the Nth measurement object set to obtain the N+1th measurement object set. In other words, the measurement range is expanded to the measurement object corresponding to priority A.

[0185] Optionally, the N+1th measurement object set can be implemented based on the following three scenarios:

[0186] Scenario 1: There is a second threshold.

[0187] Optionally, in the following scenario, the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object, and the second threshold is used to determine whether the measurement amount of the Xth measurement object satisfies the start of measurement of the Yth measurement object in one or more measurement objects, the priority of the Yth measurement object is lower than the priority of the Xth measurement object, and Y is a positive integer. At this time, it can also be considered that the terminal device determines the N+1th measurement object set in this example based on the first threshold and the second threshold. In addition, the N+1th measurement GAP is used to meet the measurement of the Nth measurement object set and the Xth measurement object.

[0188] Optionally, the second threshold is configured by the radio access network device for the Yth measurement object, and is used by the terminal device to evaluate whether the measurement amount of the Yth measurement object is less than or equal to the second threshold. Exemplarily, the second threshold may also be referred to as a low-priority measurement start threshold corresponding to the Yth measurement object, or other names may exist without limitation.

[0189] For example, taking the priorities of three measurement objects (priority #1 to priority #3), the priority order of the three priorities is reduced once, and priority #1 corresponds to measurement object #1, priority #2 corresponds to measurement object #2, and priority #3 corresponds to measurement object #3, and the Nth measurement object set includes measurement object #1. If priority #1, priority #2, and priority #3 are all configured with a low priority measurement start threshold, then the measurement object with the lowest priority in the Nth measurement object set is measurement object #1, and the low priority measurement start threshold of measurement object #1 is the first threshold. The Xth measurement object is measurement object #2, and the low priority measurement start threshold of measurement object #2 is the second threshold. Therefore, the terminal device can add measurement object #2 to the Nth measurement object set to obtain the N+1th measurement object set, which includes measurement object #1 and measurement object #2, so that the terminal device can measure the N+1th measurement object set.

[0190] Optionally, before step S604B, the communication method may further include: the radio access network device sending indication information indicating the second threshold to the terminal device. Accordingly, the terminal device receives the indication information indicating the second threshold from the radio access network device.

[0191] Scenario 2: The second threshold does not exist, but the third threshold exists.

[0192] Optionally, in scenario 2, the N+1th measurement object set also includes the Yth measurement object, the second threshold is used to determine whether the measurement amount of the Xth measurement object satisfies the requirement for initiating measurement of the Yth measurement object among one or more measurement objects, and the third threshold is used to determine whether the measurement amount of the Yth measurement object satisfies the requirement for initiating measurement of the Zth measurement object among one or more measurement objects. The priority of the Yth measurement object is lower than the priority of the Xth measurement object, and the priority of the Zth measurement object is lower than the priority of the Yth measurement object, and X, Y, and Z are all positive integers. In this case, it can also be considered that the terminal device determines the N+1th measurement object set in this example based on the first threshold and the third threshold.

[0193] Optionally, the third threshold is configured by the radio access network device for the Zth measurement object, and is used by the terminal device to evaluate whether the measurement amount of the Zth measurement object is less than or equal to the second threshold. Exemplarily, the second threshold may also be referred to as a low-priority measurement start threshold corresponding to the Zth measurement object, or other names may exist without limitation.

[0194] For example, taking the priorities of three measurement objects (priority #1 to priority #3), the priority order of the three priorities is reduced once, and priority #1 corresponds to measurement object #1, priority #2 corresponds to measurement object #2, priority #3 corresponds to measurement object #3, and the Nth measurement object set includes measurement object #1. For example, if priority #1 and priority #3 are both configured with a low priority measurement start threshold, and priority #2 is not configured with a low priority measurement start threshold, at this time, the terminal device can add measurement object #2 and measurement object #3 to the Nth measurement object set to obtain the N+1th measurement object set, which includes measurement object #1, measurement object #2 and measurement object #3, so that the terminal device can measure the N+1th measurement object set.

[0195] Optionally, before step S604B, the communication method may further include: the radio access network device sending indication information indicating the third threshold to the terminal device. Accordingly, the terminal device receives the indication information indicating the third threshold from the radio access network device.

[0196] Scenario 3: There is neither a second threshold nor a third threshold.

[0197] Optionally, in scenario three, the terminal device determines in order from high to low priority whether there are measurement objects configured with a low-priority measurement start threshold among the measurement objects whose priority is lower than the priority of the Zth measurement object, that is, among the measurement objects whose priority is lower than the priority of the Zth measurement object, the terminal device determines in order whether there are measurement objects that require further evaluation to determine whether to start measurement.

[0198] The first measurement object configured with a low-priority measurement start threshold among the measurement objects having a priority lower than that of the Zth measurement object is determined as the last measurement object added to the Nth measurement object set. That is, when the second threshold and the third threshold do not exist, the (N+1)th measurement object set includes: the Nth measurement object set, and measurement objects among the multiple measurement objects whose priorities are lower than the lowest priority in the Nth measurement object set and greater than or equal to priority B (i.e., the first measurement object configured with a low-priority measurement start threshold among the frequency points having a priority lower than that of the Zth measurement object).

[0199] Alternatively, after traversing all priorities except the highest priority among multiple measurement objects, the terminal device determines that there is no measurement object configured with a low priority measurement start threshold among all priorities among the multiple measurement objects except the lowest priority in the Nth measurement object set. At this time, the terminal device can add all measurement objects with priorities lower than the lowest priority in the Nth measurement object set among the multiple measurement objects to the Nth measurement object set, that is, the N+1th measurement object set at this time: includes the Nth measurement object set, and all measurement objects with priorities lower than the lowest priority in the Nth measurement object set among the multiple measurement objects.

[0200] For example, taking the priorities of 6 measurement objects (priority #1 to priority #6), the priorities of the 6 measurement objects decrease in sequence, and priority #1 corresponds to measurement object #1, priority #2 corresponds to measurement object #2, priority #3 corresponds to measurement object #3, priority #4 corresponds to measurement object #4, priority #5 corresponds to measurement object #5, and priority #6 corresponds to measurement object #6, and the Nth measurement object set includes measurement object #1. For example, if priority #1 and priority #5 are respectively configured with a low priority measurement start threshold, priority #2, priority #3, priority #4, and priority #6 are not configured with a low priority measurement start threshold, when it is determined that priority #3 is not configured with a low priority measurement start threshold, priority #4 continues to be judged until it is determined that priority #5 is configured with a low priority measurement start threshold. At this time, the terminal device can add measurement objects #2 to measurement objects #5 to the Nth measurement object set to obtain the N+1th measurement object set, which includes measurement objects #1 to measurement objects #5, so that the terminal device can measure the N+1th measurement object set.

[0201] Alternatively, taking the priorities of 6 measurement objects (priority #1 to priority #6), the priorities of the 6 measurement objects decrease in sequence, and priority #1 corresponds to measurement object #1, priority #2 corresponds to measurement object #2, priority #3 corresponds to measurement object #3, priority #4 corresponds to measurement object #4, priority #5 corresponds to measurement object #5, and priority #6 corresponds to measurement object #6 as an example, if priority #1 is configured with a low priority measurement start threshold, priority #2 to priority #6 are not configured with a low priority measurement start threshold, when it is determined that priority #3 is not configured with a low priority measurement start threshold, the remaining measurement objects are traversed until the last priority (i.e., priority #6) is traversed, and no priority configured with a low priority measurement start threshold is found. At this time, the terminal device can add measurement objects #2 to measurement objects #6 to the Nth measurement object set to obtain the N+1th measurement object set, which includes measurement objects #1 to measurement objects #6, so that the terminal device can measure the N+1th measurement object set.

[0202] Based on this possible implementation, when the measurement amount of the lowest-priority measurement object in the Nth measurement object set is less than or equal to the first threshold, it indicates that the measurement amount of the measurement object is poor, and therefore the measurement range needs to be expanded. Therefore, the terminal device can expand the measurement range (i.e., determine the N+1th measurement object set) based on whether there is a threshold for determining whether to start measurement of low-priority measurement objects. Compared with the solution of measuring all measurement objects, it can reduce measurement actions and calculations, save power consumption, and reduce the impact of measurement GAP on data transmission performance.

[0203] Case 2: the number of measurement objects included in the N+1th measurement object set is less than the number of measurement objects included in the Nth measurement object set.

[0204] Optionally, the terminal device may determine the N+1th measurement object set based on a fourth threshold value. The fourth threshold value is used to determine whether the measurement amount of the Mth measurement object in the Nth measurement object set satisfies the requirement of stopping measurement of measurement objects whose priority is less than that of the Mth measurement object, where M is a positive integer.

[0205] Optionally, before step S604B, the radio access network device may send indication information indicating the fourth threshold to the terminal device, and accordingly, the terminal device receives the indication information indicating the fourth threshold from the radio access network device. Exemplarily, the implementation of the indication information indicating the fourth threshold is similar to the implementation of the indication information indicating the first threshold described above. For details, reference may be made to the description of the indication information indicating the first threshold described above, and no further details are given here.

[0206] Optionally, the fourth threshold value may be a threshold value. Alternatively, it may be a threshold range. In this case, if the measurement value of the Mth measurement object is greater than or equal to the fourth threshold value, it indicates that the measurement value of the Mth measurement object is greater than or equal to the maximum value in the fourth threshold value (i.e., the threshold range). Exemplarily, the fourth threshold value may also be referred to as a low-priority measurement stop threshold corresponding to the Mth measurement object, or other names may exist without limitation.

[0207] Optionally, the low-priority measurement stop threshold and the low-priority measurement start threshold may correspond one-to-one. That is, if any priority level among multiple measurement object priorities is configured with a low-priority measurement start threshold, the priority level is also configured with a low-priority measurement stop threshold. Alternatively, the low-priority measurement stop threshold and the low-priority measurement start threshold may be configured separately and optionally, such that a certain priority level may be configured with a low-priority measurement start threshold but not a low-priority measurement stop threshold, or a certain priority level may not be configured with a low-priority measurement start threshold but may be configured with a low-priority measurement stop threshold.

[0208] For example, taking the priorities of 6 measurement objects (priority #1 to priority #6), the priorities of the 6 measurement objects decrease in sequence, and priority #1 corresponds to measurement object #1, priority #2 corresponds to measurement object #2, priority #3 corresponds to measurement object #3, priority #4 corresponds to measurement object #4, priority #5 corresponds to measurement object #5, and priority #6 corresponds to measurement object #6, and the Nth measurement object set includes measurement object #1 as an example, if priority #1, priority #3, and priority #5 are respectively configured with a low priority measurement start threshold, and priority #2, priority #4, and priority #6 are not configured with a low priority measurement start threshold, the wireless access network device may configure a low priority measurement stop threshold for part or all of priority #1, priority #3, and priority #5; or the wireless access network device may not configure a low priority measurement stop threshold for priority #1, priority #3, and priority #5; or the wireless access network device may configure a low priority measurement stop threshold for part or all of priority #2, priority #4, and priority #6.

[0209] Optionally, the terminal device may determine the N+1th measurement object set based on the fourth threshold, including: when the measurement amount of the Mth measurement object is greater than or equal to the fourth threshold, determining the N+1th measurement object set. At this time, the N+1th measurement object set includes measurement objects in the Nth measurement object set whose priority is greater than or equal to the priority of the Mth measurement object.

[0210] Optionally, in this optional solution, as shown in (b) of FIG8 , the communication method may further include step S602B: that is, step S602 may further include step S602B:

[0211] S602B. The radio access network device sends the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets to the terminal device. Correspondingly, the terminal device receives the N+1th measurement GAP from the radio access network device. That is, when the measurement amount of the Mth measurement object is greater than or equal to the fourth threshold, the terminal device receives the N+1th measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets. At this time, the N+1th measurement GAP is used to measure measurement objects that meet the priority of the Nth measurement object set that is greater than or equal to the priority of the Mth measurement object.

[0212] Optionally, before step S604B, the radio access network device may send indication information indicating the fourth threshold to the terminal device, and accordingly, the terminal device receives the indication information indicating the fourth threshold from the radio access network device. Exemplarily, the implementation of the fourth threshold is similar to that of the first threshold. For details, reference may be made to the description of the first threshold above, and no further details are given here.

[0213] Optionally, before step S602B, as shown in (b) of FIG8 , the communication method may further include step S606:

[0214] S606. The terminal device sends, to the radio access network device, instruction information for instructing the cessation of measurement of a measurement object having a priority lower than the priority of the Mth measurement object. Accordingly, the radio access network device receives, from the terminal device, instruction information for instructing the cessation of measurement of a measurement object having a priority lower than the priority of the Mth measurement object. Thus, the radio access network device may perform step S602B in (b) of FIG8 based on the instruction information. That is, step S602B in (b) of FIG8 is based on the instruction information for instructing the cessation of measurement of a measurement object having a priority lower than the priority of the Mth measurement object.

[0215] Based on the second situation, when the measurement amount of the Mth measurement object is greater than or equal to the fourth threshold value, it means that the measurement amount of the Mth measurement object is good. If the measurement objects with a priority greater than or equal to the priority of the Mth measurement object in the Nth measurement object set are continued to be measured, the terminal device is more likely to report the measurement amount. Therefore, there is no need to measure the measurement objects with a priority less than the priority of the Mth measurement object in the Nth measurement object set. Thus, the N+1th measurement object set determined by the terminal device includes the measurement objects with a priority greater than or equal to the priority of the Mth measurement object in the Nth measurement object set. Compared with the solution of measuring all measurement objects, it can reduce measurement actions and calculation amount, reduce the impact of measurement GAP on data transmission performance, and save power consumption.

[0216] Optionally, in step S605, the indication information for instructing to start measurement of the Xth measurement object, and in step S606, the indication information for instructing to stop measurement of a measurement object having a priority lower than that of the Mth measurement object, may be carried in the same information. For convenience of description, the same information is referred to as second information below. That is, the second information may indicate to start or stop measurement of a low-priority measurement object. Furthermore, the radio access network device may obtain the N+1th measurement object set through the second information, thereby further determining the N+1th measurement GAP corresponding to the N+1th measurement object set.

[0217] Exemplarily, the second information indicates to start or stop the measurement of the low-priority measurement object, which can be understood as follows: the second information implicitly indicates to start or stop the measurement of the low-priority measurement object by indicating the priority of satisfying the low-priority measurement object measurement start condition or stop condition. Specifically, the second information indicates priority information, and further indicates whether the start condition or the stop condition is satisfied to indicate the expansion or contraction of the measurement object set. Among them, satisfying the start condition can be understood as that the measurement amount of the measurement object corresponding to the priority is less than or equal to the corresponding low-priority measurement start threshold, and satisfying the stop condition can be understood as that the measurement amount of the priority is less than or equal to the corresponding low-priority measurement stop threshold. For example, when N is 1, after the terminal device measures the Nth measurement object set (i.e., the first measurement object set), when it is determined that the first measurement object in the first measurement object set satisfies the start condition / stop condition for starting the low-priority measurement object, the second information can indicate that priority #1 (the priority of the first measurement object) satisfies the start condition or stop condition, which can be understood as: indicating that the measurement amount (such as the first measurement amount) of the measurement object corresponding to priority #1 is less than or equal to the first threshold, or indicating that the measurement amount (first measurement amount) of the measurement object corresponding to priority #1 is greater than or equal to the fourth threshold. Among them, when priority #1 meets the start condition, it indicates that the Nth measurement object set needs to expand the measurement range, that is, the number of measurement objects in the N+1th measurement object set is greater than the number of measurement objects in the Nth measurement object set. When priority #1 meets the stop condition, it indicates that the Nth measurement object set needs to narrow the measurement range, that is, the number of measurement objects in the N+1th measurement object set is less than the number of measurement objects in the Nth measurement object set. Exemplarily, the process of the radio access network device determining the N+1th measurement object set is similar to the process of the terminal device determining the N+1th measurement object set in the above cases 1 and 2. Please refer to the relevant descriptions of the above cases 1 and 2, and no further details will be given here.

[0218] As a first example, the second information indication information may include a first field and a second field, where the first field indicates a priority for starting low-priority measurement (i.e., a priority corresponding to a measurement object that meets a condition for starting low-priority measurement). The second field indicates a priority corresponding to stopping low-priority measurement (i.e., a priority corresponding to a measurement object that meets a condition for stopping low-priority measurement).

[0219] For example, taking the Nth measurement object set including the first measurement object to the Qth measurement object (wherein the first measurement object to the Qth measurement object include the Mth measurement object), the priority of the Qth measurement object is priority #Q, and the priority of the Mth measurement object is priority #M, if the first field is priority #Q, then the first field indicates that the priority for starting the low priority measurement is priority #Q, that is, the Qth measurement amount (that is, the measurement amount of the Qth measurement object) is less than or equal to the low priority measurement start threshold of priority #Q (that is, the first threshold), so the measurement range needs to be expanded, that is, the number of measurement objects in the N+1th measurement object set is greater than the number of measurement objects in the Nth measurement object set.

[0220] If the second field indicates priority #M, the second field indicates that the priority for stopping low-priority measurement is priority #M. That is, the Mth measurement amount (i.e., the measurement amount of the Mth measurement object) is greater than or equal to the low-priority measurement stopping threshold (i.e., the fourth threshold) of priority #Q. Therefore, the measurement range needs to be narrowed, that is, the number of measurement objects in the (N+1)th measurement object set is less than the number of measurement objects in the (N)th measurement object set.

[0221] As a second example, the second information may include a third field and a fourth field, wherein the third field indicates priority information and the fourth field indicates whether the priority in the third field is a priority for starting low-priority measurement or a priority for stopping low-priority measurement.

[0222] Exemplarily, the value of the fourth field can be 1 bit. When the 1 bit is 1, it indicates that the priority of the third field is the priority for starting low-priority measurement. Correspondingly, when the 1 bit is 0, it indicates that the priority of the third field is the priority for stopping low-priority measurement. Alternatively, when the 1 bit is 1, it indicates that the priority of the third field is the priority for stopping low-priority measurement. Correspondingly, when the 1 bit is 0, it indicates that the priority of the third field is the priority for starting low-priority measurement. Alternatively, the fourth field can also include multiple bits. For example, the multiple bits can be 2 bits. When the 2 bits are 00, it indicates that the priority of the third field is the priority for stopping low-priority measurement. When the 2 bits are 11, it indicates that the priority of the third field is the priority for starting low-priority measurement. Alternatively, the fourth field may have other implementation forms besides the above, which are not limited by the embodiments of the present application.

[0223] When the value of the fourth field is 1, it indicates that the priority of the third field is the priority for starting low-priority measurement. Correspondingly, when the 1 bit is 0, it indicates that the priority of the third field is the priority for stopping low-priority measurement. The Nth measurement object set includes the first measurement object to the Qth measurement object (wherein the first measurement object to the Qth measurement object include the Mth measurement object), the priority of the Qth measurement object is priority #Q, and the priority of the Mth measurement object is priority #M. For example, if the third field is priority #Q and the fourth field is 1, the second information indicates that the priority for starting low-priority measurement is priority #Q, so the measurement range needs to be expanded, that is, the number of measurement objects in the N+1th measurement object set is greater than the number of measurement objects in the Nth measurement object set.

[0224] If the third field is priority #M and the fourth field is 0, the second information indicates that the priority for stopping low-priority measurement is priority #M, so the measurement range needs to be narrowed, that is, the number of measurement objects in the N+1th measurement object set is less than the number of measurement objects in the Nth measurement object set.

[0225] As a third example, the second information may include a fifth field and a sixth field, where the fifth field indicates the priority for starting measurement (i.e., the priority of the measurement object to be added to the Nth measurement object set). The sixth field indicates the priority for stopping measurement (i.e., the priority of the measurement object to be removed from the Nth measurement object set).

[0226] Exemplarily, taking the Nth measurement object set including the first measurement object to the Qth measurement object (wherein the first measurement object to the Qth measurement object include the Mth measurement object), the priority of the Qth measurement object is priority #Q, the priority of the Mth measurement object is priority #M, and priority #M is greater than priority #Q as an example, if the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object, it indicates that the priority to be started is priority #X (that is, the priority of the Xth measurement object), that is, the fifth field indicates that the priority of the measurement to be started is priority #X; if the N+1th measurement object set includes the Nth measurement object set, the Xth measurement object and the Yth measurement object, it indicates that the priority to be started is priority #X and priority #Y (that is, the priority of the Yth measurement object), that is, the fifth field indicates that the priority of the measurement to be started is priority #X and priority #Y.

[0227] If the (N+1)th measurement object set includes a measurement object whose priority in the (N)th measurement object set is greater than or equal to that of the (M)th measurement object, it indicates that the priority to be stopped is priority #Q, that is, the sixth field indicates that the priority to be stopped is priority #Q.

[0228] As a fourth example, the second information may include a seventh field and an eighth field, wherein the seventh field indicates priority information and the eighth field indicates whether the priority in the seventh field is a priority for starting measurement or a priority for stopping measurement.

[0229] Exemplarily, the value of the eighth field can be 1 bit. When the 1 bit is 1, it indicates that the priority of the seventh field is the priority for starting measurement. Correspondingly, when the 1 bit is 0, it indicates that the priority of the seventh field is the priority for stopping measurement. Alternatively, when the 1 bit is 1, it indicates that the priority of the seventh field is the priority for stopping measurement. Correspondingly, when the 1 bit is 0, it indicates that the priority of the seventh field is the priority for starting measurement. Alternatively, the eighth field may also include multiple bits, which is not limited in the embodiments of the present application.

[0230] Taking the value of the eighth field as 1 bit, when the bit is 1, it indicates that the priority of the eighth field is the priority for starting measurement. Correspondingly, when the bit is 0, it indicates that the priority of the eighth field is the priority for stopping measurement. The Nth measurement object set includes the first measurement object to the Qth measurement object (wherein the first measurement object to the Qth measurement object include the Mth measurement object), the priority of the Qth measurement object is priority #Q, the priority of the Mth measurement object is priority #M, and priority #M is greater than priority #Q. For example, if the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object, it indicates that the priority to be started is priority #X (i.e., the priority of the Xth measurement object), that is, the seventh field indicates that the priority to be started is priority #X, and the eighth field is 1; if the N+1th measurement object set includes the Nth measurement object set, the Xth measurement object, and the Yth measurement object, it indicates that the priorities to be started are priority #X and priority #Y (i.e., the priority of the Yth measurement object), that is, the seventh field indicates priority #X and priority #Y, and the eighth field is 1.

[0231] If the (N+1)th measurement object set includes a measurement object whose priority is greater than or equal to that of the (M)th measurement object in the (N)th measurement object set, it indicates that the priority to be stopped is priority #Q, that is, the seventh field indicates priority #Q and the eighth field is 0.

[0232] The above exemplary embodiment takes the one-to-one correspondence between measurement objects and priorities as an example to exemplify the implementation of the second information; the correspondence between measurement objects and priorities can also be many-to-one. For example, the measurement object corresponding to priority #X can include the Xth measurement object #1 and the Xth measurement object #2. Then the second information indicates that the priority for starting the measurement is priority #X, which means that the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object #1 and the Xth measurement object #2.

[0233] Case 3: The number of measurement objects included in the N+1th measurement object set is equal to the number of measurement objects included in the Nth measurement object set.

[0234] Optionally, the terminal device may determine the N+1th measurement object set based on the first threshold. Exemplarily, when there is a first threshold and the measurement amount of the measurement object with the lowest priority in the Nth measurement object set is greater than the first threshold, the N+1th measurement set is equal to the Nth measurement object set.

[0235] Optionally, in case three, the terminal device re-measures / continues to measure the Nth measurement object set, so that it can determine whether the measurement amount obtained by the latest measurement meets the measurement reporting condition corresponding to the measurement amount based on the measurement amount obtained by the latest measurement. Exemplarily, the terminal device can re-measure / continue to measure the Nth measurement object set within the Nth measurement GAP.

[0236] Based on this situation three, when the measurement amount of the measurement object with the lowest priority in the Nth measurement object set is greater than the first threshold, it means that the measurement amount of the measurement object is good, so there is no need to expand the measurement range. If the Nth measurement object set is still measured, the terminal device is more likely to report the measurement amount. In other words, the terminal device needs to continue to measure only the Nth measurement object set. Compared with the solution of measuring all measurement objects, it can reduce measurement actions and calculations, save power consumption, and reduce the impact of measurement GAP on data transmission performance.

[0237] Optionally, when the measurement quantity of the measurement object in the N+1th measurement object set meets the measurement reporting condition, the terminal device can report the measurement quantity.

[0238] When no measurement amount of a measurement object in the N+1th measurement object set satisfies the measurement reporting condition, if the measurement object with the lowest priority in the N+1th measurement object set is the measurement object with the lowest priority among the priorities of one or more measurement objects, that is, at this time, the N+1th measurement object set includes all measurement objects in the one or more measurement objects; then the terminal device may report the measurement amounts of all measurement objects in the one or more measurement objects, and none of them satisfies the measurement reporting condition. This allows the radio access network device to implement cell handover through other methods, thereby avoiding radio link failure in the current cell caused by the terminal device's delay in handover.

[0239] If the minimum priority in the N+1th measurement object set is greater than the minimum priority among the priorities of one or more measurement objects, the terminal device may determine the N+2th measurement object set. Exemplarily, the implementation of the N+2th measurement object set is similar to the implementation of the above-mentioned N+1th measurement object set. For details, reference may be made to the implementation of the above-mentioned N+1th measurement object set, which will not be repeated here.

[0240] In a second possible implementation, the terminal device obtains measurement GAPs corresponding to one or more measurement object sets, including: the terminal device determines the measurement GAPs corresponding to the one or more measurement object sets from a first correspondence, wherein the first correspondence includes a correspondence between the measurement object sets and the measurement GAPs.

[0241] Optionally, the first correspondence is sent by the wireless access network device to the terminal device. Exemplarily, the first correspondence is sent by the wireless access network device to the terminal device via first information; that is, the first information also indicates the first correspondence. Alternatively, the first correspondence is sent by the wireless access network device to the terminal device via other information in addition to the first information.

[0242] Optionally, the terminal device determines the measurement GAPs corresponding to one or more measurement object sets from the first corresponding relationship, including: determining the measurement GAP corresponding to the Nth measurement object set in the one or more measurement object sets in the first corresponding relationship as the Nth measurement GAP.

[0243] Optionally, when the N+1th measurement object set includes the Nth measurement object set, the N+1th measurement GAP is equal to the Nth measurement GAP. In this case, the terminal device does not need to determine the N+1th measurement GAP from the first corresponding relationship, and can directly use the Nth measurement GAP to measure the N+1th measurement object set. Therefore, the terminal device determines the measurement GAPs corresponding to one or more measurement object sets from the first corresponding relationship, including: when the N+1th measurement object set is not equal to the Nth measurement object set, determining the measurement GAP corresponding to the N+1th measurement object set in one or more measurement object sets in the first corresponding relationship as the N+1th measurement GAP.

[0244] As an example, the first corresponding relationship can be represented in the form of expression.

[0245] In one possible implementation, when the first threshold, the second threshold, and the third threshold exist, the first correspondence relationship may include the following content:

[0246] Table 4

[0247] In Table 4 above, the first to Mth measurement objects can be understood as follows: measurement object set #(n-1) includes measurement objects with a priority greater than that of the Mth measurement object in one or more measurement object sets. In other words, the measurement object with the lowest priority in measurement object set #(n-1) is the Mth measurement object. Similarly, the first to Qth measurement objects can be understood as follows: measurement object set #n includes measurement objects with a priority greater than that of the Qth measurement object in one or more measurement object sets. In other words, the measurement object with the lowest priority in measurement object set #n is the Qth measurement object. The first to Xth measurement objects can be understood as follows: measurement object set #(n+1) includes measurement objects with a priority greater than that of the Xth measurement object in one or more measurement object sets. In other words, the measurement object with the lowest priority in measurement object set #(n+1) is the Xth measurement object. The first to Yth measurement objects can be understood as follows: measurement object set #(n+2) includes measurement objects with a priority greater than that of the Yth measurement object in one or more measurement object sets. In other words, the measurement object with the lowest priority in measurement object set #(n+2) is the Yth measurement object.

[0248] According to the above, when the value of N is 1, the first measurement object set includes the first measurement object. Combined with Table 4 above, it can be seen that the measurement object set #1 in Table 4 above is the first measurement object set. Therefore, the terminal device can use the measurement GAP #1 corresponding to the first measurement object set (i.e., measurement object set #1) as the first measurement GAP. Similarly, since the value of N is not 1, the measurement object with the lowest priority in the Nth measurement object set is the Qth measurement object. The measurement object set #n in Table 4 above is the Nth measurement object set. Therefore, the terminal device can use the measurement GAP #n corresponding to the Nth measurement object set (i.e., measurement object set #n) as the Nth measurement GAP.

[0249] When the N+1th measurement object set includes the Nth measurement object set and the Xth measurement object, the measurement object set #(n+1) in the above Table 4 is the N+1th measurement object set. Therefore, the terminal device can use the measurement GAP#(n+1) corresponding to the N+1th measurement object set (i.e., measurement object set #(n+1)) as the N+1th measurement GAP.

[0250] When the N+1th measurement object set includes measurement objects whose priority is greater than or equal to that of the Mth measurement object in the Nth measurement object set, the measurement object set #(n-1) in the above Table 4 is the N+1th measurement object set. Therefore, the terminal device can use the measurement GAP#(n-1) corresponding to the N+1th measurement object set (i.e., measurement object set #(n-1)) as the N+1th measurement GAP.

[0251] In another possible implementation, when the first threshold and the third threshold exist, and the second threshold does not exist, the first correspondence relationship may include the following content:

[0252] Table 5

[0253] In Table 5 above, the descriptions of the first measurement object to the Mth measurement object, the first measurement object to the Qth measurement object, and the first measurement object to the Xth measurement object can refer to the relevant descriptions in Table 4 above. In addition, the process of determining the Nth measurement GAP based on the Nth measurement object set is the same as the process of determining the Nth measurement GAP based on the Nth measurement object set in Table 4 above. Please refer to the description in Table 4 and will not be repeated here.

[0254] When the (N+1)th measurement object set includes the (N)th measurement object set, the (X)th measurement object, and the (Y)th measurement object, since the first to (Y)th measurement objects are measurement objects with a priority greater than or equal to the (Y)th measurement object among one or more measurement objects, and the priorities of the (Q)th, (X)th, and (Y)th measurement objects decrease in sequence, the first to (Y)th measurement objects are equivalent to the (N)th, (X)th, and (Y)th measurement objects. Therefore, the (N+1)th measurement object set in Table 5 is the (N+1)th measurement object set. Therefore, the terminal device may use the measurement GAP #(n+1) corresponding to the (N+1)th measurement object set (i.e., the (N+1)th measurement object set) as the (N+1)th measurement GAP.

[0255] When the N+1th measurement object set includes measurement objects whose priority is greater than or equal to that of the Mth measurement object in the Nth measurement object set, the measurement object set #(n-1) in the above Table 5 is the N+1th measurement object set. Therefore, the terminal device can use the measurement GAP#(n-1) corresponding to the N+1th measurement object set (i.e., measurement object set #(n-1)) as the N+1th measurement GAP.

[0256] As another example, the first corresponding relationship may be represented in the form of a set.

[0257] In a first possible implementation, the odd-numbered columns in the first correspondence are represented as a measurement object set, and the even-numbered columns are represented as a measurement GAP, and the measurement object set and the measurement GAP correspond one to one.

[0258] Exemplarily, taking the first correspondence relationship including the content in Table 4 as an example, the first correspondence relationship can be {measurement object set #1 (first measurement object set), measurement GAP #1;…; measurement object #(n-1) (first measurement object to Mth measurement object), measurement GAP #(n-1); measurement object set #n (first measurement object to Qth measurement object), measurement GAP #n; measurement object set #(n+1) (first measurement object to Xth measurement object), measurement GAP #(n+1); measurement object set #(n+2) (first measurement object to Yth measurement object), measurement GAP #(n+2);...;}.

[0259] In a second possible implementation, the first correspondence may include two sets, set #1 includes one or more measurement object sets, and set #2 includes one or more measurement GAPs corresponding to the measurement object sets, respectively. The elements in set #1 correspond one-to-one to the elements in set #2.

[0260] For example, taking the first correspondence relationship including the content in Table 4 as an example, the first correspondence relationship may include: Set #1: {Measurement Object Set #1; ...; Measurement Object Set #(n-1); Measurement Object Set #n; Measurement Object Set #(n+1); Measurement Object Set #(n+2); ...;}. And Set 2: {Measurement GAP #1; ...; Measurement GAP #(n-1); Measurement GAP #n; Measurement GAP #(n+1); Measurement GAP #(n+2); ...;}. Among them, Measurement Object Set #1 corresponds to Measurement GAP #1, ..., Measurement Object Set #(n-1) corresponds to Measurement GAP #(n-1), Measurement Object Set #n corresponds to Measurement GAP #n, Measurement Object Set #(n+1) corresponds to Measurement GAP #(n+1), and Measurement Object Set #(n+2) corresponds to Measurement GAP #(n+2).

[0261] In a third possible implementation, the first correspondence may include a set, where one or more measurement gaps are respectively corresponding to measurement object sets. The elements in the set are gradually increased according to the order in the set, and the number of measurement objects included in the measurement object set corresponding to each element in the set is also gradually increased according to the order in the set.

[0262] For example, taking the first correspondence relationship including the content in Table 4 as an example, the first correspondence relationship may include: Set #1: {Measurement GAP #1; ...; Measurement GAP #(n-1); Measurement GAP #n; Measurement GAP #(n+1); Measurement GAP #(n+2); ...;}. Measurement object set #1 corresponds to measurement GAP #1, ..., measurement object set #(n-1) corresponds to measurement GAP #(n-1), measurement object set #n corresponds to measurement GAP #n, measurement object set #(n+1) corresponds to measurement GAP #(n+1), and measurement object set #(n+2) corresponds to measurement GAP #(n+2).

[0263] In the above three possible implementations, the first correspondence relationship including the content in Table 4 is taken as an example to describe the first correspondence relationship represented in the form of a set. When the first correspondence relationship includes the content in Table 5, the implementation of the first correspondence relationship represented in the form of a set is similar to the implementation of the first correspondence relationship represented in the form of a set when the above first correspondence relationship includes the content in Table 4. For details, please refer to the relevant descriptions in the above three possible implementations, and no further details will be given here.

[0264] Optionally, in a second possible implementation manner, the terminal device and the radio access network device default the first measurement GAP to the measurement GAP corresponding to the minimum measurement object set.

[0265] Optionally, in a second possible implementation, after the terminal device determines the Nth measurement GAP, the communication method further includes: the terminal device sending indication information indicating the Nth measurement GAP to the wireless access network device. Accordingly, the wireless access network device may receive the indication information indicating the Nth measurement GAP from the terminal device.

[0266] Based on this optional solution, the terminal device may notify the radio access network device of the Nth measurement GAP. After receiving the Nth measurement GAP, the radio access network device suspends data transmission between the terminal device and the Nth measurement GAP, thereby avoiding packet loss caused by the radio access network device transmitting data to the terminal device within the Nth measurement GAP, while the terminal device is unable to receive the data within the Nth measurement GAP.

[0267] The above example uses a one-to-one correspondence between measurement objects and priorities as an example to exemplify the implementation of the Nth measurement object set, the Nth measurement GAP, the N+1th measurement object set, and the N+1th measurement GAP. The correspondence between measurement objects and priorities can also be many-to-one. For example, the measurement objects corresponding to priority #X may include the Xth measurement object #1 and the Xth measurement object #2. Then, the N+1th measurement object set includes the Nth measurement object set, the Xth measurement object #1, and the Xth measurement object #2. In this case, the N+1th measurement GAP is used for measurements that meet the requirements of the Nth measurement object set, the Xth measurement object #1, and the Xth measurement object #2, and will not be further described here.

[0268] Optionally, the Nth measurement object set may also include measurement objects corresponding to the frequency of the primary serving cell of the terminal device.

[0269] Optionally, before the terminal device measures the first measurement object set, the communication method further includes: measuring the measurement object corresponding to the frequency of the primary serving cell of the terminal device, and determining whether the measurement amount of the measurement object corresponding to the frequency of the primary serving cell meets the measurement reporting condition. The measurement amount of the measurement object corresponding to the frequency of the primary serving cell includes the measurement amount of the primary serving cell and the measurement amount of the co-frequency neighboring cell.

[0270] When the measurement amount of the measurement object corresponding to the frequency of the primary serving cell meets the measurement reporting condition, the terminal device reports the measurement amount that meets the measurement reporting condition. When the measurement amount of the measurement object corresponding to the frequency of the primary serving cell does not meet the measurement reporting condition, the terminal device may determine, based on a fifth threshold, whether to enable measurement of the first measurement object, that is, whether to add the first measurement object to the measurement range to obtain a first measurement object set.

[0271] Based on this optional solution, when the measurement amount of the primary serving cell is less than or equal to the fifth threshold, it indicates that the measurement amount of the primary serving cell is poor and cell switching is required. Therefore, it is necessary to start neighboring cell measurement. The neighboring cell measurement may include same-frequency neighboring cell measurement and different-frequency neighboring cell measurement. Based on this, the measurement amount of the same-frequency neighboring cell is first evaluated to determine whether the reporting conditions are met. If the measurement amount of the same-frequency neighboring cell meets the third measurement reporting condition, the target cell determined by the wireless access network device is the cell in the same-frequency neighboring cell, and there is no need to start different-frequency measurement, thereby ensuring that the performance impact caused by the measurement GAP required for measuring different frequencies is reduced when determining the target cell.

[0272] Exemplarily, the implementation of the fifth threshold is similar to that of the first threshold. For details, please refer to the relevant description of the first threshold, which will not be repeated here. The fifth threshold may be the threshold for starting neighboring cell measurement (s-measureconfig). The fifth threshold is used by the terminal device to determine whether to start measuring the first measurement object.

[0273] Optionally, the terminal device may determine whether to enable measurement of the first measurement object based on a fifth threshold value, including: when the measurement amount of the primary serving cell is less than or equal to the fifth threshold value, it indicates that the measurement amount of the primary serving cell is poor, and it may be necessary to determine whether the measurement amount of the co-frequency neighboring area meets the measurement reporting condition, or it may be necessary to further expand the measurement range to measure other measurement objects in addition to the measurement object corresponding to the frequency point of the primary serving cell. Therefore, it is necessary to enable evaluation of the measurement amount of the co-frequency neighboring area, and further enable measurement of the first measurement object with the highest priority. Exemplarily, the terminal device determines whether the measurement amount of the co-frequency neighboring area meets the measurement reporting condition. When the measurement amount of the co-frequency neighboring area meets the measurement reporting condition, the terminal device may report the measurement amount of the co-frequency neighboring area. When the measurement amount of the co-frequency neighboring area does not meet the measurement reporting condition, the terminal device may determine whether to enable measurement of the first measurement object based on the fifth threshold value. For example, when the measurement amount of the co-frequency neighboring area is less than or equal to the fifth threshold value, measurement of the first measurement object is enabled, that is, the terminal device needs to measure the first measurement object set. When the measurement amount of the same-frequency neighboring area is greater than the fifth threshold, the terminal device does not need to expand the measurement range and can continue to measure the objects corresponding to the frequency of the main serving cell. At this time, the set of measurement objects that the terminal device needs to measure includes the measurement objects corresponding to the frequency of the main serving cell.

[0274] Optionally, if at least one of the measurement amount of the primary serving cell or the measurement amount of the same-frequency neighboring cell is greater than the fifth threshold, the terminal device needs to continue / persist on the measurement object corresponding to the frequency of the primary serving cell, that is, the measurement object set that the terminal device needs to measure includes the measurement object corresponding to the frequency of the primary serving cell. Since the measurement object set does not include the measurement objects corresponding to the frequencies of hetero-frequency or hetero-system cells, the measurement GAP corresponding to the measurement object set can be considered to have no GAP configured. Optionally, when measuring the first measurement object set, the terminal device can also continue to measure the measurement objects corresponding to the frequency of the primary serving cell, that is, the first measurement object can also include the measurement objects corresponding to the frequency of the primary serving cell. Similarly, when measuring the Nth measurement object set / the N+1th measurement object set, the terminal device can also continue to measure the measurement objects corresponding to the frequency of the primary serving cell, that is, the Nth measurement object set / the N+1th measurement object set can also include the measurement objects corresponding to the frequency of the primary serving cell.

[0275] Optionally, when the Nth measurement object set / the N+1th measurement object set includes measurement objects corresponding to the frequency of the primary serving cell, the first correspondence may include the following content:

[0276] In one possible implementation, when the first threshold, the second threshold, and the third threshold exist, the first correspondence relationship may include the following content:

[0277] Table 6

[0278] In another possible implementation, when the first threshold and the third threshold exist, and the second threshold does not exist, the first correspondence relationship may include the following content:

[0279] Table 7

[0280] The implementation of the parameters in Table 6 and Table 7 is similar to that of the parameters in Table 4 and Table 5 above. For details, please refer to the relevant descriptions in Table 4 and Table 5 above and will not be repeated here.

The "module" here may refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and memory that executes one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0315] In some embodiments, when the communication device 90 in Figure 9 is a chip or a chip system, the function / implementation process of the transceiver module 902 can be implemented through the input and output interface (or communication interface) of the chip or chip system, and the function / implementation process of the processing module 901 can be implemented through the processor (or processing circuit) of the chip or chip system.

[0316] Since the communication device 90 provided in this embodiment can execute the above method, the technical effects that can be obtained can refer to the above method embodiments and will not be repeated here.

[0317] As a possible product form, the wireless access network device or terminal device described in the embodiments of the present application can also be implemented using the following: one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits that can perform the various functions described throughout this application.

[0318] As another possible product form, the wireless access network device or terminal device of the embodiment of the present application can be implemented by a general bus architecture. For ease of explanation, refer to Figure 10, which is a structural diagram of a communication device 1000 provided in an embodiment of the present application, and the communication device 1000 includes a processor 1001 and a transceiver 1002. The communication device 1000 can be a terminal device, or a chip or chip system therein; or, the communication device 100 can be a wireless access network device, or a chip or module therein. Figure 10 only shows the main components of the communication device 1000. In addition to the processor 1001 and the transceiver 1002, the communication device may further include a memory 1003, and an input and output device (not shown in the figure).

[0319] Optionally, processor 1001 is primarily used to process communication protocols and communication data, as well as control the entire communication device, execute software programs, and process software program data. Memory 1003 is primarily used to store software programs and data. Transceiver 1002 may include a radio frequency circuit and an antenna. The radio frequency circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves.

[0321] When the communication device is powered on, the processor 1001 can read the software program in the memory 1003, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 1001 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1001. The processor 1001 converts the baseband signal into data and processes the data.
