Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method, device and system. Background Art

[0002] When performing mobility management, the terminal device can measure the synchronization signal block (SSB) and send a measurement report to the network device when the measurement result meets the reporting conditions. The network device can perform mobility management on the terminal device based on the measurement report. For example, the network device can determine whether to switch the terminal device from the current cell to another cell based on the measurement report.

[0003] At present, new terminal equipment, such as reduced capability UE (RedCap UE), has been introduced into mobile communication systems (e.g., the 5th generation (5G) mobile communication systems). Among them, RedCap UE can measure at least one of the measurement objects (MO) of the cell defining SSB (CD-SSB), non-cell defining SSB (NCD-SSB), and ordinary SSB in heterogeneous transmission, and send a measurement report to the network device.

[0004] Among them, "different frequency" means that the frequency is different from the serving cell of the RedCap UE. Ordinary SSB refers to SSB transmitted outside the bandwidth part (BWP). The measurement results included in the measurement report can indicate parameters such as signal quality, so that the network equipment can switch the RedCap UE to a better cell based on the measurement results, thereby providing better service quality for the user.

[0005] However, when performing inter-frequency measurement, if the number of measurement objects to be measured is large, the power consumption of the RedCap UE will be large. Summary of the invention

[0006] The present application provides a communication method, apparatus and system for reducing the power consumption of a terminal device when performing heterofrequency measurement.

[0007] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a terminal device or a chip or circuit in a terminal device, the method comprising: receiving heterofrequency measurement configuration information from a network device, the heterofrequency measurement configuration information comprising a first measurement object, the frequency corresponding to the first measurement object is different from the frequency of a service cell of the terminal device, wherein the first measurement object comprises at least one of a measurement object of a cell-defined synchronization signal block CD-SSB, a measurement object of a non-cell-defined synchronization signal block NCD-SSB, or a measurement object of a first SSB; measuring a target measurement object in the first measurement object according to a priority of at least one of CD-SSB, NCD-SSB, or the first SSB.

[0008] In this embodiment, when performing inter-frequency measurement, the terminal device may measure the target measurement object in the first measurement object instead of measuring all measurement objects in the first measurement object, so that the number of measurement objects measured by the terminal device can be reduced, thereby effectively reducing the power consumption of the terminal device. In addition, the terminal device may measure the target measurement object according to the priority of the signal. For example, the target measurement object is determined according to the priority of the signal, so that a signal with a higher priority can be measured first, which helps to ensure mobility and thus ensure the continuity of the terminal service.

[0009] Optionally, the first SSB is an SSB transmitted outside a bandwidth part (bandwidth part, BWP), for example, the first SSB is an SSB transmitted on a specific frequency.

[0010] In one possible implementation, the priority of at least one of CD-SSB, NCD-SSB, or the first SSB satisfies one or more of the following: the priority of CD-SSB is higher than the priority of NCD-SSB; the priority of CD-SSB is higher than the priority of the first SSB; or, the priority of the first SSB is higher than the priority of NCD-SSB.

[0011] For example, when the frequency of the current service cell is the NCD-SSB frequency, when measuring NCD-SSB and CD-SSB without activated BWP, the terminal device can measure the measurement results of the current service area based on the measurement results of NCD-SSB1, but cannot measure the neighboring areas of the current service area based on the measurement results of NCD-SSB. However, the terminal device can measure the measurement results of the neighboring areas of the current service area based on the measurement results of CD-SSB, and the process of switching based on the measurement results of CD-SSB can be considered as same-frequency mobility switching on the network device side. In view of this, the priority of CD-SSB can be set to be higher than the priority of NCD-SSB and / or the priority of the first SSB, so that the terminal device can give priority to measuring the measurement object of CD-SSB. In this way, after the terminal device reports the measurement results of CD-SSB to the network device, the terminal device can measure the measurement results of the neighboring cells of the current service area based on the measurement results of CD-SSB, and decide whether to switch to the neighboring cells of the current service area, so that the same-frequency mobility switching can be triggered. By triggering the same-frequency mobility switching, the terminal device can obtain a stronger signal, further ensuring the continuity of the terminal service.

[0012] For another example, when the first SSB is an SSB transmitted on a specific frequency corresponding to a neighboring cell of the current service cell, and the frequency of the neighboring cell is outside the BWP, the network device can compare the signal quality of the current service cell and the neighboring cell of the current service cell based on the measurement result of the first SSB. If the signal quality of the neighboring cell of the current service cell is better or more suitable for the current conditions, the network device can trigger the terminal device to switch to the neighboring cell of the current service cell more quickly. Therefore, the priority of the first SSB can be set to a higher priority. For example, the priority of the first SSB can be set to be higher than the priority of the NCD-SSB, so that the terminal device can give priority to measuring the measurement object of the first SSB during heterofrequency measurement. Since the SSB transmitted on a specific frequency corresponding to the neighboring cell of the current service cell is measured, the cell with better signal quality can be found more quickly, thereby improving the efficiency of cell switching of the terminal device.

[0013] In a possible implementation, the number of frequencies corresponding to the target measurement object is less than or equal to the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. In this implementation, the target measurement object is determined in combination with the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, so that the inter-frequency measurement process can be performed within the capability of the terminal device.

[0014] In a possible implementation, the target measurement object in the first measurement object is measured according to the priority of at least one of CD-SSB, NCD-SSB, or the first SSB, including: measuring the target measurement object according to the priority of any one of CD-SSB, NCD-SSB, or the first SSB. In this implementation, during hetero-frequency measurement, the terminal device can measure the measurement object of the higher priority signal (such as CD-SSB) among CD-SSB, NCD-SSB, and the first SSB. For example, for some signals of higher importance, the terminal device considers them to be more important, so they can be measured first during hetero-frequency measurement.

[0015] In another possible implementation, the target measurement object in the first measurement object is measured according to the priority of at least one of CD-SSB, NCD-SSB, or the first SSB, including: measuring the target measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB. In this implementation, when the terminal device considers that two types of signals in CD-SSB, NCD-SSB, or the first SSB are more important, the measurement object of the high priority signal can be measured first according to the priority of these two types of signals during the inter-frequency measurement. Alternatively, in the case where CD-SSB, NCD-SSB, and the first SSB have different priorities, the measurement object of the high priority signal can be measured first according to the priority of these three types of signals during the inter-frequency measurement.

[0016] Optionally, before measuring the target measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB, the method further includes: determining the target measurement object from the first measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB. In this implementation, the terminal device may select the target measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB before measuring, and then measure the selected target measurement object; in this way, the measurement object of the high priority signal can be determined as the target object. Optionally, in the case where the target measurement object includes two types of measurement objects of high priority signals (such as CD-SSB and the first SSB), the terminal device can still measure the target measurement object according to the priority order when measuring, so that the measurement object of the high priority signal is measured first.

[0017] In a possible implementation, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is a first number; the method further includes: when the first number is less than or equal to the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, determining that the target measurement object includes the measurement object of CD-SSB, the measurement object of the first SSB, and the measurement object of NCD-SSB in the first measurement object. In this implementation, the target measurement object is determined in combination with the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device and the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB, so that the inter-frequency measurement can be performed within the capability of the terminal device.

[0018] In a possible implementation manner, the total number of frequencies corresponding to the CD-SSB, NCD-SSB, and the first SSB is a first number, and the total number of frequencies corresponding to the CD-SSB and the first SSB is a second number; the method further includes: when the first number is greater than the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, and the second number is less than or equal to the upper limit, determining that the target measurement object includes the measurement object of the CD-SSB in the first measurement object and the measurement object of the first SSB. In this implementation manner, the total number of frequencies corresponding to the CD-SSB, NCD-SSB, and the first SSB is divided into the first number, and the total number of frequencies corresponding to the CD-SSB and the first SSB is divided into the second number, so that the terminal device can determine the measurement object of the signal with high priority as the target measurement object within the capability of the terminal device by comparing the first number, the second number and the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device.

[0019] In a possible implementation, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is a first number, the total number of frequencies corresponding to CD-SSB and the first SSB is a second number, and the total number of frequencies corresponding to CD-SSB is a third number; accordingly, according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB, the target measurement object is determined from the first measurement object, including: when the first number and the second number are greater than the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device, and the third number is less than or equal to the upper limit, according to the priority order of CD-SSB, NCD-SSB, and the first SSB, the target measurement object is determined to include the measurement object of CD-SSB in the first measurement object. In this embodiment, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is divided into a first number, the total number of frequencies corresponding to CD-SSB and the first SSB is divided into a second number, and the total number of frequencies corresponding to CD-SSB is divided into a third number, so that the terminal device can determine the measurement object of the high-priority signal as the target measurement object within the capability of the terminal device by comparing the first number, the second number, the third number with the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device.

[0045] First, some terms in this application are explained to facilitate understanding by those skilled in the art.

[0046] 1) Terminal equipment is a device that provides voice and / or data connectivity to users. Terminal equipment can also be called user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal (MT), wireless communication equipment, terminal agent or terminal equipment, etc.

[0047] For example, the terminal device may be a handheld device with a wireless connection function, or a vehicle with a communication function, a vehicle-mounted device (such as a vehicle-mounted communication device, a vehicle-mounted communication chip), etc. At present, some examples of terminal devices are: mobile phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistant (PDA) devices, handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, tablet computers, computers with wireless transceiver functions, laptops, PDAs, mobile Internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0048] In the embodiment of the present application, the terminal device needs to measure the neighboring cells of the serving cell of the terminal. The serving cell where the terminal device is located may have one or more neighboring cells. When the terminal device is at the edge of the serving cell, it may measure the neighboring cells, and may thereby trigger cell reselection or cell switching.

[0049] 2) Network equipment, such as access network (AN) equipment and / or core network (CN) equipment. Among them, the access network equipment can be an entity that can receive and transmit wireless signals, responsible for providing wireless access-related services to terminal devices within its coverage, and realizing physical layer functions, resource scheduling and wireless resource management, quality of service (QoS) management, wireless access control and mobility management functions. As a node in the wireless access network, the access network equipment can also be called a base station, a radio access network (RAN) node (or device), or an access point (AP).

[0050] For example, the access network equipment may include a new generation Node B (gNB), a transmission reception point (TRP), an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a transmission point (TRP), a transmitting point (TP), a mobile switching center, a home base station (e.g., home evolved NodeB, or home Node B, HNB), or a base band unit (BBU), etc.

[0051] In addition, in a network structure, the access network device may include a centralized unit (CU) node and a distributed unit (DU). This structure splits the protocol layer of the access network device, places the functions of some protocol layers under central control of the CU, and distributes the functions of the remaining part or all of the protocol layers in the DU, which is centrally controlled by the CU. For example, the CU is responsible for processing non-real-time protocols and services, and realizing the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and realizing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer.

[0052] Optionally, the access network device may also include an active antenna unit (AAU). The AAU implements some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by the DU+AAU.

[0053] The access network device may include one or more of CU, DU, and AAU. Alternatively, CU may also be divided into a network device in CN, which is not limited in the embodiment of the present application.

[0054] 3) RedCap UE.

[0055] Compared with legacy terminal devices, RedCap UE is a terminal device with reduced capabilities. For example, compared with legacy terminal devices, the following performance of RedCap UE is reduced: maximum bandwidth capability, number of transmit and receive antennas / antenna channels, maximum multiple input multiple output (MIMO) layer capability, maximum modulation order capability, support for half-duplex frequency division duplexing (FDD) (half duplex FDD, HD-FDD), etc.

[0056] Compared with traditional terminal devices, RedCap UE supports smaller bandwidth. For example, RedCap UE can support 20 MHz bandwidth in frequency range 1 (FR1) or 100 MHz bandwidth in FR2, while traditional terminal devices can support 100 MHz bandwidth in FR1 or 200 MHz bandwidth in FR2.

[0057] 4) BWP is a concept in wireless communication used to divide and manage spectrum resources. In 5G and other similar wireless communication systems, spectrum resources are usually divided into different BWPs, each of which represents a portion of spectrum resources. Each BWP has its own bandwidth and scheduling rules to support different communication requirements and service types.

[0058] 5) SSB, which can be used by the terminal device to perform timing synchronization and measurement operations. The SSB in the embodiment of the present application may include CD-SSB, NCD-SSB, or the first SSB.

[0059] Among them, CD-SSB is continuously distributed in the frequency domain. The terminal device can obtain the system information block (SIB) 1 based on the CD-SSB, so as to perform at least one of the following operations: timing synchronization, radio link monitoring (RLM), beam failure detection (BFD), radio resource management (RRM) measurement, or beam management. CD-SSB will be associated with a specific BWP, that is, CD-SSB is transmitted on a specific BWP.

[0060] NCD-SSB is distributed non-continuously in the frequency domain. In addition, NCD-SSB is an additional SSB configured for new terminal devices (for example, RedCap UE). Since RedCap UE is limited by the maximum bandwidth capability. When the currently activated BWP of RedCap UE does not contain CD-SSB, RedCap UE can use NCD-SSB for timing synchronization and measurement and other operations. NCD-SSB will be associated with a specific BWP, that is, NCD-SSB is transmitted on a specific BWP.

[0061] The first SSB may not be associated with any BWP, that is, the first SSB is an SSB transmitted outside the BWP.

[0062] 6) Measuring object (MO), in the new radio (NR) network, a measurement object is associated with a reference signal for measurement, that is, a measurement object refers to a measurement object corresponding to a reference signal. Multiple reference signals correspond to multiple measurement objects. For example, a CD-SSB signal includes multiple CD-SSBs, and the measurement object of CD-SSB includes multiple measurement objects.

[0063] Among them, one measurement object corresponds to the carrier frequency, measurement window, and configuration information of a reference signal; wherein the carrier frequency refers to the carrier frequency of transmitting the one reference signal, the measurement window refers to the measurement timing (timestamp for measuring the one reference signal) and the measurement period of the one reference signal, and the configuration information may indicate the type of the one reference signal. For example, the type of the reference signal may include SSB or channel state information reference signal (channel state information-reference signal, CSI-RS), wherein SSB may include at least one of CD-SSB, NCD-SSB, or the first SSB.

[0064] In the embodiments of the present application, for the number of nouns, unless otherwise specified, it means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. "At least one of the following items (individuals)" or similar expressions refers to any combination of these items (individuals), including any combination of singular items (individuals) or plural items (individuals). In addition, it should be understood that in the description of the present application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and should not be understood as indicating or implying relative importance, nor should they be understood as indicating or implying order.

[0065] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE), Universal Mobile Telecommunications System (UMTS) system, Code Division Multiple Access (CDMA) system, Wireless Local Area Network (WLAN), fifth generation (5G) communication system, sixth generation (6G) communication system or other future evolution systems, or other various wireless communication systems using wireless access technology, etc. As long as there is a need for cell residence in the communication system, the technical solutions of the embodiments of the present application can be adopted.

[0066] For example, Figure 1 A possible communication system applicable to the embodiments of the present application includes a network device and a terminal device (eg Figure 1 The terminal device a and the terminal device b are shown in FIG. 1 . The terminal device may establish a connection with one network device to form a single-connection communication system, or may establish a connection with two network devices to form a dual-connectivity (DC) communication system.

[0067] The terminal device can measure the neighboring cells of the terminal device's serving cell and trigger cell switching or other actions. For example, after the terminal device performs RRM measurement, the network device can perform mobility management on the terminal device based on the RRM measurement result of the terminal device, such as switching the terminal device from the serving cell to another cell with better signal quality. Figure 2 , introduces the process of cell switching of terminal equipment.

[0068] S201: The source access network device sends measurement configuration information to the terminal device. Correspondingly, the terminal device receives the measurement configuration information.

[0069] The measurement configuration information may include (or indicate) at least one of the following: a measurement object, a report configuration, or a measurement ID. The measurement object is used to indicate the object on which the terminal device performs measurement, and the report configuration is used to configure the measurement reporting criteria and the measurement report format, wherein the measurement reporting criteria are the conditions for triggering the terminal device to perform measurement reporting (i.e., triggering the terminal device to send a measurement report). A measurement ID may be associated with one or more measurement objects, and may also be associated with a report configuration.

[0070] S202: The terminal device performs measurement according to the measurement configuration information, and sends a measurement report to the source access network device when the measurement reporting criteria are met. Correspondingly, the source access network device receives the measurement report.

[0071] Specifically, if the reference signal associated with the measurement object indicated by the measurement configuration information is SSB, the terminal device may measure the SSB. When the measurement reporting criteria are met, the terminal device may send the obtained measurement report to the network device.

[0072] S203: The source access network device sends a switching request message to the target access network device. Correspondingly, the target access network device receives the switching request message.

[0073] The source access network device receives a measurement report from the terminal device. If it is determined according to the measurement report to switch the terminal device to the target access network device, the source access network device sends a switching request message to the target access network device.

[0074] S204: The target access network device sends a switching confirmation message to the source access network device. Correspondingly, the source access network device receives the switching confirmation message from the target access network device.

[0075] After receiving the handover request information, the target access network device may decide whether to allow the terminal device to switch to the target access network device. If the terminal device is allowed to switch to the target access network device, the target access network device may execute S204. The handover confirmation information may include parameters such as the cell radio network temporary identifier (C-RNTI) allocated to the terminal device and / or the target access network device security-related algorithm.

[0076] S205: The source access network device sends an RRC reconfiguration message to the terminal device. Correspondingly, the terminal device receives the RRC reconfiguration message.

[0077] After receiving the handover confirmation message from the target access network device, the source access network device may send an RRC reconfiguration message to the terminal device. The RRC reconfiguration message may be regarded as a handover command, instructing the terminal device to handover to the target access network device.

[0078] S206: The terminal device initiates random access to the target access network device to access the target access network device.

[0079] The terminal device receives the RRC reconfiguration information and may execute S206.

[0080] Figure 2 In the measurement process shown, the process of measuring the service frequency corresponding to the currently activated BWP is called same-frequency measurement; the measurement of other frequencies except the service frequency is called different-frequency measurement. Figure 2 If the measurement process in is an inter-frequency measurement, the measurement objects configured by the above measurement configuration information may include measurement objects of CD-SSB, NCD-SSB, or the first SSB. If the number of corresponding measurement objects of CD-SSB, NCD-SSB, and ordinary SSB is large, the measurement power consumption of the terminal device will be large.

[0081] In view of this, in an embodiment of the present application, when performing inter-frequency measurement, the terminal device may measure the target measurement object in the first measurement object configured by the network device, rather than measuring all measurement objects in the first measurement object, so that the number of frequencies measured by the terminal device can be reduced, thereby effectively reducing the power consumption of the terminal device. Moreover, the terminal device may measure from the target measurement object according to the priority of the signal. For example, the target measurement object is determined according to the priority of the signal, so that a signal with a higher priority can be measured first, which is helpful to measure the neighboring area of ​​the current service area.

[0082] The following is a description of the solution provided by the embodiment of the present application in conjunction with the accompanying drawings. Figure 3 , a flow chart of a communication method provided in an embodiment of the present application, which can be applied to Figure 1 In the communication system shown.

[0083] S301: The network device sends inter-frequency measurement configuration information to the terminal device. Correspondingly, the terminal device receives the inter-frequency measurement configuration information from the network device, where the inter-frequency measurement configuration information includes a first measurement object.

[0084] In an embodiment of the present application, the frequency corresponding to the first measurement object is different from the frequency of the service cell of the terminal device, so for the terminal device, the first measurement object is an inter-frequency measurement object. The first measurement object includes one or more measurement objects, and one measurement object is associated with a reference signal for measurement, and the reference signal may include at least one of CD-SSB, NCD-SSB, or the first SSB. Accordingly, the first measurement object may include at least one of the measurement object of CD-SSB, the measurement object of NCD-SSB, or the measurement object of the first SSB. The frequency corresponding to the first measurement object may be the frequency corresponding to the measurement object included in the first measurement object, for example, the frequency corresponding to the first measurement object includes at least one of the frequency of CD-SSB, the frequency of NCD-SSB, or the frequency of the first SSB. Among them, CD-SSB is associated with the first BWP, that is, CD-SSB is transmitted in the first BWP; NCD-SSB is associated with the second BWP, that is, NCD-SSB is transmitted in the second BWP; SSB is not associated with BWP, that is, the first SSB is transmitted outside the BWP, for example, at a specific frequency outside the BWP (for example, the frequency of the neighboring cell of the terminal device serving cell, and the frequency of the neighboring cell is outside the BWP). Among them, the first BWP is different from the second BWP, and both the first BWP and the second BWP can be BWPs that the network device has configured for the terminal device but are in an inactive state.

[0085] The network device can flexibly configure the first measurement object according to the activation status of the BWP. For example, the BWP activated at time T1 is BWP1, and the unactivated BWPs include BWP2, BWP3, and BWP4. BWP1 is associated with CD-SSB1, BWP2 is associated with NCD-SSB1, BWP3 is associated with NCD-SSB2, and BWP4 is associated with NCD-SSB3. Then the first measurement object configured by the network device includes the measurement object of NCD-SSB1, the measurement object of NCD-SSB2, and the measurement object of NCD-SSB3; the BWP activated at time T2 is BWP2, and the unactivated BWPs include BWP1, BWP3, and BWP4. BWP1 is associated with CD-SSB1, BWP2 is associated with NCD-SSB1, BWP3 is associated with NCD-SSB2, and BWP4 is associated with NCD-SSB3. Then the first measurement object configured by the network device includes the measurement object of CD-SSB1, the measurement object of NCD-SSB2, and the measurement object of NCD-SSB3.

[0086] Optionally, the inter-frequency measurement configuration information may be carried in an RRC message, for example, the RRC message is an RRC reconfiguration (RRCreconfiguration) message.

[0087] Optionally, the heterodyne measurement configuration information may also include a reporting configuration and / or a measurement identifier, etc. The reporting configuration is used to configure the measurement reporting rules and the format of the measurement report, and the measurement identifier can be used to associate a measurement object and a reporting configuration. In this way, the terminal device may include the corresponding measurement identifier in the reported measurement report so that the network device can determine which measurement the measurement report is the result of. For example, the first measurement object includes a measurement object of CD-SSB and a measurement object of NCD-SSB, the measurement identifier associated with the measurement object of CD-SSB is MeasId1, and the reporting configuration associated with the measurement object of CD-SSB is the first reporting configuration; the measurement identifier associated with the measurement object of NCD-SSB is MeasId2, and the reporting configuration associated with the measurement object of NCD-SSB is the second reporting configuration. In other words, for measurements based on CD-SSB and NCD-SSB, the network device associates both measurements with reporting configurations. Among them, the first reporting configuration and the second reporting configuration may be the same or different.

[0088] Among them, the reporting configuration may include at least one of the following: reporting criteria, reporting cycle, the total number of reported measurement reports, the maximum number of reported cells, or the reference signal type of the reported measurement result. Correspondingly, after the terminal device measures the target measurement object, the terminal device can also evaluate whether the measurement results of the service area and / or the neighboring area meet the reporting conditions according to the reporting criteria in the inter-frequency measurement configuration information, and report when the measurement results meet the reporting conditions. In this way, invalid reporting of the terminal device can be reduced, thereby further reducing the power consumption of the terminal device.

[0089] Among them, the reporting criteria are the criteria for triggering the terminal device to perform measurement reporting (i.e., triggering the terminal device to send a measurement report). The types of reporting criteria may include periodic reporting and / or event-triggered reporting, etc. Periodic reporting is to report the measurement report according to a set period. For example, the terminal device may perform periodic reporting according to a periodic reporting timer, and the timing duration of the periodic reporting timer is the set period. The events corresponding to the event-triggered reporting may include: events in which the measurement results continue to meet the requirements within a first time period. For example, when the signal quality of multiple measurement results obtained by the terminal device for measuring multiple NCD-SSBs within a first time period are all higher than a preset threshold, the terminal device sends a measurement report; when the terminal device measures multiple NCD-SSBs within the first time period, and the signal quality in the measurement result of a certain NCD-SSB is lower than the preset threshold, the terminal device does not send a measurement report. Among them, the signal quality may be signal strength, and the parameters used to reflect or indicate the signal strength may include at least one of the following: reference signal receiving power (reference signal receiving power, RSRP), reference signal receiving quality (reference signal receiving quality, RSRQ) and received signal strength indication (received signal strength indication, RSSI).

[0090] S302: The terminal device measures the target measurement object in the first measurement object according to the priority of at least one of CD-SSB, NCD-SSB, or the first SSB.

[0091] In S302, when performing inter-frequency measurement, the terminal device may measure the target measurement object in the first measurement object instead of measuring all measurement objects in the first measurement object, so that the number of measurement objects measured by the terminal device can be reduced, thereby effectively reducing the power consumption of the terminal device. In addition, the terminal device may measure from the target measurement object according to the priority of the signal. For example, the target measurement object is determined according to the priority of the signal, so that a signal with a higher priority can be measured first, which helps to improve the measurement accuracy.

[0092] In an embodiment of the present application, the priority of at least one of CD-SSB, NCD-SSB, or the first SSB satisfies one or more of the following: the priority of CD-SSB is higher than the priority of NCD-SSB; the priority of CD-SSB is higher than the priority of the first SSB; or, the priority of the first SSB is higher than the priority of NCD-SSB.

[0093] For example, when the frequency of the current service cell is the NCD-SSB frequency, when measuring NCD-SSB and CD-SSB without activated BWP, the terminal device can measure the measurement results of the current service area based on the measurement results of NCD-SSB1, but cannot measure the neighboring areas of the current service area based on the measurement results of NCD-SSB. However, the terminal device can measure the measurement results of the neighboring areas of the current service area based on the measurement results of CD-SSB, and the process of switching based on the measurement results of CD-SSB can be considered as same-frequency mobility switching on the network device side. In view of this, the priority of CD-SSB can be set to be higher than the priority of NCD-SSB and / or the priority of the first SSB, so that the terminal device can give priority to measuring the measurement object of CD-SSB. In this way, after the terminal device reports the measurement results of CD-SSB to the network device, the terminal device can measure the measurement results of the neighboring cells of the current service area based on the measurement results of CD-SSB, and decide whether to switch to the neighboring cells of the current service area, so that the same-frequency mobility switching can be triggered. By triggering the same-frequency mobility switching, the terminal device can obtain a stronger signal, further ensuring the continuity of the terminal service.

[0094] For another example, when the first SSB is an SSB transmitted on a specific frequency corresponding to a neighboring cell of the current service cell, and the frequency of the neighboring cell is outside the BWP, the network device can compare the signal quality of the current service cell and the neighboring cell of the current service cell based on the measurement result of the first SSB. If the signal quality of the neighboring cell of the current service cell is better or more suitable for the current conditions, the network device can trigger the terminal device to switch to the neighboring cell of the current service cell more quickly. Therefore, the priority of the first SSB can be set to a higher priority. For example, the priority of the first SSB can be set to be higher than the priority of the NCD-SSB, so that the terminal device can give priority to measuring the measurement object of the first SSB during heterofrequency measurement. Since the SSB transmitted on a specific frequency corresponding to the neighboring cell of the current service cell is measured, the cell with better signal quality can be found more quickly, thereby improving the efficiency of cell switching of the terminal device.

[0095] In the embodiment of the present application, the target measurement object can be determined in combination with the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, and the number of frequencies of the target measurement object is set to be less than or equal to the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. In this way, the inter-frequency measurement process is performed within the capability of the terminal device.

[0096] In the embodiment of the present application, the terminal device measures the target measurement object in the first measurement object according to the priority of at least one of CD-SSB, NCD-SSB, or the first SSB, which may include but is not limited to the following implementation methods:

[0097] In implementation mode 1, the terminal device measures the target measurement object in the first measurement object according to the priority of any one of CD-SSB, NCD-SSB, or the first SSB. In this way, during hetero-frequency measurement, the terminal device can measure the measurement object of the higher priority signal (such as CD-SSB) among CD-SSB, NCD-SSB, and the first SSB. For example, for some signals of higher importance, the terminal device considers them to be more important, so they can be measured preferentially during hetero-frequency measurement.

[0098] In case 1, the terminal device considers that the priority of CD-SSB is higher than the priority of NCD-SSB and the priority of the first SSB, so the terminal device preferentially measures the measurement object of CD-SSB in the first measurement object, and stops measuring when the number of frequencies of the measured CD-SSB measurement objects reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. For example, see Figure 4A , the currently inactivated BWPs are BWP1-BWP4, the CD-SSB associated with BWP1 is CD-SSB1, the CD-SSB associated with BWP2 is CD-SSB2, the CD-SSB associated with BWP3 is CD-SSB3, and the CD-SSB associated with BWP4 is CD-SSB4. Correspondingly, the first measurement object includes MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, and MO4 corresponding to CD-SSB4. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 3, any three of MO1, MO2, MO3, and MO4 are target measurement objects, and the terminal device stops measuring after measuring any three of MO1, MO2, MO3, and MO4. Alternatively, if the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 4 or 5, MO1, MO2, MO3, and MO4 are all target measurement objects, and the terminal device measures MO1, MO2, MO3, and MO4 one by one.

[0099] In case 2, the terminal device considers that the priority of the first SSB is higher than that of the NCD-SSB, so the terminal device preferentially measures the measurement object of the first SSB in the first measurement object, and stops measuring when the number of frequencies of the measured measurement object of the first SSB reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. For example, see Figure 4B, the first SSB includes SSB1-SSB4, and accordingly, the first measurement object includes MO1 corresponding to SSB1, MO2 corresponding to SSB2, MO3 corresponding to SSB3, and MO4 corresponding to SSB4. If the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device is 3, any three of MO1, MO2, MO3, and MO4 are target measurement objects, and the terminal device stops measuring after measuring any three of MO1, MO2, MO3, and MO4. Alternatively, if the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device is 4 or 5, MO1, MO2, MO3, and MO4 are all target measurement objects, and the terminal device measures MO1, MO2, MO3, and MO4 one by one.

[0100] Case 3: In the same-frequency mobility trigger scenario, the terminal device considers CD-SSB to be more important, and the terminal device prioritizes measuring the measurement object of CD-SSB in the first measurement object. When the frequency number of the measured CD-SSB measurement object reaches the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device, the measurement is stopped.

[0101] In case 4, the terminal device considers that the first SSB is more important, so the terminal device gives priority to measuring the measurement object of the first SSB, and stops measuring when the frequency number of the measured measurement object of the first SSB reaches the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device.

[0102] In case 5, the terminal device considers NCD-SSB to be more important, then the terminal device prioritizes measuring the measurement object of NCD-SSB in the first measurement object, and stops measuring when the frequency number of the measured NCD-SSB measurement object reaches the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device.

[0103] In the second implementation mode, the terminal device measures the target measurement object in the first measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB. In this way, when the terminal device believes that two types of signals among CD-SSB, NCD-SSB, or the first SSB are more important, the measurement object of the high priority signal can be measured first according to the priority of these two types of signals during the inter-frequency measurement. Alternatively, in the case where CD-SSB, NCD-SSB, and the first SSB have different priorities, the measurement object of the high priority signal can be measured first according to the priority of these three types of signals during the inter-frequency measurement.

[0104] Since there are multiple situations in the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB: the priority of CD-SSB is higher than the priority of NCD-SSB, the priority of CD-SSB is higher than the priority of the first SSB, and the priority of the first SSB is higher than the priority of NCD-SSB. Accordingly, the terminal device measures the target measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB, which may include but not be limited to the following situations:

[0105] In case 1, the terminal device considers that the priority of CD-SSB is higher than that of NCD-SSB, then the terminal device measures the measurement object of CD-SSB first, and stops measuring when the frequency number of the measurement object of CD-SSB currently measured reaches the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, or, after measuring all the measurement objects of CD-SSB, if the frequency number of all the measurement objects of CD-SSB does not reach the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, measures the measurement object of NCD-SSB, and stops measuring when the frequency number of the CD-SSB and NCD-SSB currently measured reaches the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device. For example, see Figure 4C, the currently inactivated BWPs are BWP1-BWP8, the CD-SSB associated with BWP1 is CD-SSB1, the CD-SSB associated with BWP2 is CD-SSB2, the CD-SSB associated with BWP3 is CD-SSB3, the CD-SSB associated with BWP4 is CD-SSB4, the NCD-SSB associated with BWP5 is NCD-SSB1, the NCD-SSB associated with BWP6 is NCD-SSB2, the NCD-SSB associated with BWP7 is NCD-SSB3, and the NCD-SSB associated with BWP8 is NCD-SSB4; accordingly, the first measurement object includes MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, MO4 corresponding to CD-SSB4, MO5 corresponding to NCD-SSB1, MO6 corresponding to NCD-SSB2, MO7 corresponding to NCD-SSB3, and MO8 corresponding to NCD-SSB4. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 3, the target measurement objects in the first measurement object are any three of MO1, MO2, MO3, and MO4, and the terminal device stops measuring after measuring any three of MO1, MO2, MO3, and MO4. Alternatively, if the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 5, the target measurement objects in the first measurement object are MO1, MO2, MO3, MO4, and any one of MO5, MO6, MO7, and MO8, and the terminal device stops measuring after measuring MO1, MO2, MO3, and MO4, and any one of MO5, MO6, MO7, and MO8.

[0106] In case 2, the terminal device considers that the priority of CD-SSB is higher than that of the first SSB, and the terminal device measures the measurement object of CD-SSB first, and stops measuring when the frequency number of the measurement object of CD-SSB currently measured reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, or, after measuring all the measurement objects of CD-SSB, if the frequency number of all the measurement objects of CD-SSB does not reach the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, measures the measurement object of the first SSB, and stops measuring when the frequency number of the currently measured CD-SSB and the first SSB reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. For example, see Figure 4D, the currently inactive BWPs are BWP1-BWP4, the CD-SSB associated with BWP1 is CD-SSB1, the CD-SSB associated with BWP2 is CD-SSB2, the CD-SSB associated with BWP3 is CD-SSB3, and the CD-SSB associated with BWP4 is CD-SSB4; the first SSB includes SSB1 and SSB2; accordingly, the first measurement object includes MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, MO4 corresponding to CD-SSB4, MO5 corresponding to SSB1, and MO6 corresponding to SSB2. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 3, the target measurement objects in the first measurement object are any three of MO1, MO2, MO3, and MO4, and the terminal device stops measuring after measuring any three of MO1, MO2, MO3, and MO4. Alternatively, if the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device is 6, the target measurement objects in the first measurement object are MO1, MO2, MO3, MO4, MO5 and MO6, and the terminal device measures MO1, MO2, MO3, and MO4, as well as MO5 and MO6.

[0107] In case 3, the terminal device considers that the priority of the first SSB is higher than that of the NCD-SSB. Then the terminal device first measures the measurement object of the first SSB, and stops measuring when the frequency number of the measurement object of the first SSB currently measured reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. Alternatively, after measuring all the measurement objects of the first SSB, if the frequency number of all the measurement objects of the first SSB does not reach the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, the terminal device measures the measurement object of NCD-SSB, and stops measuring when the frequency number of the first SSB and NCD-SSB currently measured reaches the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device. For example, see Figure 4E, the first SSB includes SSB1-SSB4, the currently unactivated BWP is BWP5-BWP8, the NCD-SSB associated with BWP5 is NCD-SSB1, the NCD-SSB associated with BWP6 is NCD-SSB2, the NCD-SSB associated with BWP7 is NCD-SSB3, and the NCD-SSB associated with BWP8 is NCD-SSB4; accordingly, the first measurement object includes MO1 corresponding to SSB1, MO2 corresponding to SSB2, MO3 corresponding to SSB3, MO4 corresponding to SSB4, MO5 corresponding to NCD-SSB1, MO6 corresponding to NCD-SSB2, MO7 corresponding to NCD-SSB3, and MO8 corresponding to NCD-SSB4. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 3, the target measurement objects in the first measurement object are any three of MO1, MO2, MO3, and MO4, and the terminal device stops measuring after measuring any three of MO1, MO2, MO3, and MO4. Alternatively, if the upper limit of the number of heterodyne measurement frequencies supported by the terminal device is 7, the target measurement objects in the first measurement object are any three of MO1, MO2, MO3, and MO4, and MO5, MO6, MO7, and MO8. The terminal device first measures MO1, MO2, MO3, and MO4, and then measures any three of MO5, MO6, MO7, and MO8.

[0108] Case 4: The terminal device considers that the priority of CD-SSB is higher than that of the first SSB, and the priority of the first SSB is higher than that of NCD-SSB. Accordingly, when the priority of CD-SSB is higher than that of the first SSB, and the priority of the first SSB is higher than that of NCD-SSB, the terminal device first measures the measurement object of CD-SSB, and stops measuring when the frequency number of the currently measured measurement object of CD-SSB reaches the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device; or, after measuring all measurement objects of CD-SSB, when the frequency number of all measurement objects of CD-SSB does not reach the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, the terminal device measures the measurement object of the first SSB, and stops measuring when the frequency number of the currently measured first SSB and CD-SSB reaches the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device; or, after measuring all measurement objects of the first SSB and CD-SSB, when the frequency number of the first SSB and NCD-SSB does not reach the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, the terminal device measures the measurement object of NCD-SSB. For example, see Figure 4F, the currently inactivated BWPs are BWP1-BWP4, the CD-SSB associated with BWP1 is CD-SSB1, the NCD-SSB associated with BWP2 is NCD-SSB1, the NCD-SSB associated with BWP3 is NCD-SSB2, and the NCD-SSB associated with BWP4 is NCD-SSB3; the first SSB includes SSB4-SSB6; accordingly, the first measurement object includes MO1 corresponding to CD-SSB1, MO2 corresponding to NCD-SSB1, MO3 corresponding to NCD-SSB2, MO4 corresponding to NCD-SSB3, MO5 corresponding to SSB4, MO6 corresponding to SSB5, and MO7 corresponding to SSB6. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 1, the target measurement object in the first measurement object is MO1, and the terminal device stops measuring after measuring MO1. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 4, the target measurement objects in the first measurement object are MO1, MO5, MO6, and MO7, and the terminal device stops measuring after measuring MO1, MO5, MO6, and MO7. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 6, the target measurement objects in the first measurement object are MO1, MO5, MO6, and MO7, and any two of MO2, MO3, and MO4, and the terminal device first measures MO1, MO5, MO6, and MO7, and then measures any two of MO2, MO3, and MO4.

[0109] In implementation mode three, the terminal device determines the target measurement object in the first measurement object according to the priority order of at least two of CD-SSB, NCD-SSB, or the first SSB, and then measures the target measurement object. In this way, when the target measurement object determined by the terminal device includes a measurement object of a type of high priority signal (such as CD-SSB), the terminal device can measure the target measurement object randomly instead of in the priority order, which can effectively simplify the measurement process; or, when the target measurement object includes two types of measurement objects of high priority signals (such as CD-SSB and the first SSB), the terminal device can still measure the target measurement object in the priority order, so that the measurement object of the high priority signal is measured first.

[0110] In case 1, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is the first number; when the first number is less than or equal to the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device, the target measurement object is determined to include the measurement object of CD-SSB in the first measurement object, the measurement object of the first SSB, and the measurement object of NCD-SSB. In this way, the target measurement object is determined in combination with the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device and the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB, so that the inter-frequency measurement can be performed within the capability of the terminal device.

[0111] For example, see Figure 4G , when the terminal device considers that the priority of CD-SSB is higher than that of the first SSB, and the priority of the first SSB is higher than that of NCD-SSB, the currently inactive BWPs are BWP1-BWP6, the CD-SSB associated with BWP1 is CD-SSB1, the CD-SSB associated with BWP2 is CD-SSB2, the CD-SSB associated with BWP3 is CD-SSB3, the CD-SSB associated with BWP4 is CD-SSB4, the NCD-SSB associated with BWP5 is NCD-SSB1, and BWP6 The associated NCD-SSB is NCD-SSB2, and the first SSB includes SSB1 and SSB2; accordingly, the first measurement object includes MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, and MO4 corresponding to CD-SSB4, MO5 corresponding to NCD-SSB1, MO6 corresponding to NCD-SSB2, MO7 corresponding to SSB1, and MO8 corresponding to SSB2, and the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is 8. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 9, the terminal device determines MO1, MO2, MO3, MO4, MO5, MO6, MO7, and MO8 as target measurement objects. Since the priority of CD-SSB is higher than that of the first SSB, and the priority of the first SSB is higher than that of NCD-SSB, the terminal device measures MO1, MO2, MO3, MO4, MO7, MO8, MO5, and MO6 in sequence.

[0112] Case 2: The total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is the first number, and the total number of frequencies corresponding to CD-SSB and the first SSB is the second number; when the first number is greater than the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, and the second number is less than or equal to the upper limit, it is determined that the target measurement object includes the measurement object of CD-SSB and the measurement object of the first SSB in the first measurement object. In this way, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is divided into the first number, and the total number of frequencies corresponding to CD-SSB and the first SSB is divided into the second number, so that the terminal device can determine the target measurement object by comparing the first number, the second number, and the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device.

[0113] For example, see Figure 4G , when the terminal device considers that the priority of CD-SSB is higher than that of the first SSB, the measurement objects of CD-SSB include MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, and MO4 corresponding to CD-SSB4, the measurement objects of NCD-SSB include MO5 corresponding to NCD-SSB1 and MO6 corresponding to NCD-SSB2, and the measurement objects of the first SSB include MO7 corresponding to SSB1 and MO8 corresponding to SSB2, then the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is 8, and the total number of frequencies corresponding to CD-SSB and the first SSB is 6. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 6, the terminal device determines MO1, MO2, MO3, MO4, MO7, and MO8 as target measurement objects, and measures MO1, MO2, MO3, MO4, MO7, and MO8 in sequence. Alternatively, if the total number of frequencies corresponding to CD-SSB and the first SSB is 6, and if the upper limit of the number of heterodyne measurement frequencies supported by the terminal device is 5, the terminal device determines MO1, MO2, MO3, MO4, and MO7 as target measurement objects, or the terminal device determines MO1, MO2, MO3, MO4, and MO8 as target measurement objects, and measures MO1, MO2, MO3, and MO4 in turn, and measures any one of MO7 and MO8.

[0114] For example, if the terminal device considers that the priority of CD-SSB is higher than that of NCD-SSB, please continue to refer to Figure 4G, the measurement objects of CD-SSB include MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, and MO4 corresponding to CD-SSB4; the measurement objects of NCD-SSB include MO5 corresponding to NCD-SSB1 and MO corresponding to NCD-SSB2, and the total number of frequencies corresponding to CD-SSB and NCD-SSB is 6. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 5, the terminal device determines MO1, MO2, MO3, MO4, and MO7 as target measurement objects, and measures MO1, MO2, MO3, MO4, and MO7 in sequence, or the terminal device determines MO1, MO2, MO3, MO4, and MO8 as target measurement objects, and measures MO1, MO2, MO3, MO4, and MO8 in sequence.

[0115] Case 3, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is the first number, the total number of frequencies corresponding to CD-SSB and the first SSB is the second number, and the total number of frequencies corresponding to CD-SSB is the third number; when the first number and the second number are greater than the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device, and the third number is less than or equal to the upper limit, the terminal device determines that the target measurement object includes the measurement object of CD-SSB in the first measurement object. In this way, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is divided into the first number, the total number of frequencies corresponding to CD-SSB and the first SSB is divided into the second number, and the total number of frequencies corresponding to CD-SSB is divided into the third number, so that the terminal device can determine the measurement object of the signal with high priority as the target measurement object within the capability of the terminal device by comparing the first number, the second number, the third number with the upper limit of the number of hetero-frequency measurement frequencies supported by the terminal device.

[0116] For example, see Figure 4G, when the terminal device considers that the priority of CD-SSB is higher than that of the first SSB and NCD-SSB, the measurement objects of CD-SSB include MO1 corresponding to CD-SSB1, MO2 corresponding to CD-SSB2, MO3 corresponding to CD-SSB3, and MO4 corresponding to CD-SSB4; the measurement objects of NCD-SSB include MO5 corresponding to NCD-SSB1 and MO6 corresponding to NCD-SSB2; the measurement objects of the first SSB include MO7 corresponding to SSB1 and MO8 corresponding to SSB2; thus, the total number of frequencies corresponding to CD-SSB, NCD-SSB, and the first SSB is 8, the total number of frequencies corresponding to CD-SSB and the first SSB is 6, and the total number of frequencies corresponding to CD-SSB is 4. If the upper limit of the number of inter-frequency measurement frequencies supported by the terminal device is 4, the terminal device determines MO1, MO2, MO3, and MO4 as target measurement objects, and measures MO1, MO2, MO3, and MO4 in turn. Alternatively, if the upper limit of the number of heterodyne measurement frequencies supported by the terminal device is 3, the terminal device determines any three of MO1, MO2, MO3, and MO4 as target measurement objects, and measures MO1, MO2, MO3, and MO4 in sequence.

[0117] For ease of understanding, the following Figure 5 The technical solution provided in the embodiments of the present application is described in more detail.

[0118] S501. A first access network device sends a switching indication message to a terminal device. Correspondingly, the terminal device receives the switching indication message. The switching indication message may indicate that a currently activated BWP of the terminal device is switched to a target BWP (i.e., a BWP to be activated at the next moment), and the target BWP corresponds to a second access network device.

[0119] Optionally, the switching indication information may be carried in DCI.

[0120] S502: The terminal device switches the activated BWP to the target BWP, and initiates random access to the second access network device.

[0121] S503: The second access network device sends inter-frequency measurement configuration information to the terminal device. Correspondingly, the terminal device receives the inter-frequency measurement configuration information.

[0122] S504: The terminal device determines a target measurement object from the first measurement object indicated by the inter-frequency measurement configuration information.

[0123] Specifically, the network device may indicate one or more frequency points corresponding to the first measurement object for the heterofrequency measurement configuration information of the target BWP. In one possible implementation, the terminal device may receive BWP configuration information from the network device, and the BWP configuration information indicates the frequencies corresponding to the CD-SSB, NCD-SSB, and the first SSB. Accordingly, the terminal device may determine the one or more frequencies corresponding to the first measurement object indicated by the heterofrequency measurement configuration information in combination with the BWP configuration information, and generate a corresponding heterofrequency configuration list according to the priority of the CD-SSB, the priority of the first SSB, and the priority of the NCD-SSB. Please refer to Figure 6 , when the priority of CD-SSB is higher than the priority of the first SSB, and the priority of the first SSB is higher than the priority of NCD-SSB, the terminal device determines the frequency of the first measurement object indicated by the hetero-frequency measurement configuration information. If the measurement object 1 in the current first measurement object is the CD-SSB frequency, further determine whether the CD-SSB frequency belongs to the target BWP. When the CD-SSB frequency does not belong to the target BWP, insert the measurement object 1 at the first position of the hetero-frequency configuration list. Alternatively, if the measurement object 2 in the current first measurement object is the first SSB frequency (i.e., the frequency transmitted outside the target BWP), insert the measurement object 2 into the hetero-frequency configuration list at a position after the CD-SSB frequency. Alternatively, if the measurement object 3 in the current first measurement object is the NCD-SSB frequency, and the NCD-SSB frequency does not belong to the target BWP, insert the measurement object 3 into the hetero-frequency configuration list at a position after the measurement object 2.

[0124] In the process of judging one or more frequencies of the first measurement object indicated by the heterofrequency measurement configuration information, the terminal device also needs to judge whether the number of measurement objects in the heterofrequency configuration list is greater than the upper limit of the number of frequencies of heterofrequency measurement supported by the terminal device; if the number of measurement objects in the heterofrequency configuration list is greater than the upper limit of the number of frequencies of heterofrequency measurement supported by the terminal device, the terminal device stops judging the frequency of the measurement object indicated by the heterofrequency measurement configuration information; if the number of measurement objects in the heterofrequency configuration list is less than or equal to the upper limit of the number of frequencies of heterofrequency measurement supported by the terminal device, the terminal device continues to judge the frequency of the measurement object indicated by the heterofrequency measurement configuration information. The measurement objects in the heterofrequency configuration list are target measurement objects.

[0125] Example 1: The upper limit of the number of frequencies supported by the terminal device for heterofrequency measurement is 7. The first measurement object indicated by the heterofrequency measurement configuration information includes measurement objects MO1-MO5. The terminal device judges the frequencies of measurement objects MO1-MO5 in sequence; wherein, the frequency of measurement object MO1 is a CD-SSB frequency, and the CD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO2-MO3 are NCD-SSB frequencies, and the NCD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO4-MO5 are the first SSB frequencies. Accordingly, after the terminal device judges the frequencies of measurement objects MO1-MO5 in sequence, the generated heterofrequency configuration list is as follows: Figure 7 As shown, the terminal device follows Figure 7 Perform inter-frequency measurement by sorting the measurement objects in the inter-frequency configuration list.

[0126] Example 2: The upper limit of the number of frequencies for heterofrequency measurement supported by the terminal device is 4. The first measurement object indicated by the heterofrequency measurement configuration information includes measurement objects MO1-MO5. The terminal device judges the frequencies of measurement objects MO1-MO5 in turn; wherein, measurement object MO2 is a CD-SSB frequency, and the CD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO4-MO5 are NCD-SSB frequencies, and the NCD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO1 and MO3 are the frequencies of the first SSB; since the total number of frequencies of CD-SSB frequency, NCD-SSB frequency and the first SSB frequency is greater than the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device, but the total number of frequencies of CD-SSB frequency and the first SSB frequency is less than the upper limit, the terminal device gives priority to measuring the measurement objects of CD-SSB frequency and the first SSB frequency. Therefore, the heterofrequency configuration list corresponding to the heterofrequency measurement configuration information is as follows: Figure 8 As shown, the terminal device follows Figure 8 Perform inter-frequency measurement by sorting the measurement objects in the inter-frequency configuration list.

[0127] Example 3, the upper limit value of the heterofrequency measurement object supported by the terminal device is 1, and the first measurement object indicated by the heterofrequency measurement configuration information includes measurement objects MO1-MO5, and the terminal device judges the frequencies of measurement objects MO1-MO5 in turn; wherein, the frequency of measurement object MO2 is CD-SSB frequency, and the CD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO4-MO5 are NCD-SSB frequencies, and the NCD-SSB frequency does not belong to the target BWP; the frequencies of measurement objects MO1 and MO3 are the first SSB frequencies; since the total frequency of CD-SSB frequency and the first SSB frequency is greater than the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device, and the CD-SSB frequency is less than the upper limit of the number of heterofrequency measurement frequencies supported by the terminal device, the terminal device gives priority to measuring the measurement object of CD-SSB frequency, so the heterofrequency configuration list corresponding to the heterofrequency measurement configuration information is as follows Fig. 9 As shown, the terminal device follows Fig. 9 Perform heterofrequency measurement on the measurement object.

[0128] S505: The terminal device measures the target measurement object.

[0129] S506: The terminal device reports the measurement result to the second network device.

[0130] Specifically, the above-mentioned inter-frequency measurement configuration indicates the reporting criteria of the inter-frequency configuration. After the terminal device measures the target measurement object, it can evaluate whether the measurement result meets the reporting criteria. When it is determined that the measurement result meets the reporting criteria, the terminal device reports the measurement result to the second network device. The second network device can decide whether to perform cell switching based on the measurement result.
