[0040] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art are within the scope of protection of the present application.

[0041] The professional terms involved in the embodiments of the present application will be described below.

[0042] 1. Mobility management measurement

[0043] Generally, the mobility management measurement can also be referred to as a radio resource management (RRM) measurement. In a wireless communication system, accurate measurement of cell quality and beam quality is the basis for effective implementation of radio resource management and mobility management. For the 5th generation (5G) new radio (NR), currently, two main categories of reference signals are considered as measurement reference signals, namely SSB and channel state information reference signal (CSI-RS) th

[0044] For SSB-based measurement, the base station configures the measurement resource of SSB for the terminal through high-layer signaling, so that the terminal performs corresponding measurement operations.

[0045] For CSI-RS-based measurement, the base station can configure one or more CSI-RS resources for the terminal to make measurements through high-layer signaling. First, in terms of cells (or in terms of cell granularity), high-layer signaling can give cell-level CSI-RS configuration parameters, such as cell ID, cell measurement bandwidth, resource density, and the like. In addition, since each cell can configure multiple CSI-RS resources, further parameter configuration also includes configuration information at the level of each CSI-RS resource, such as CSI-RS index, time domain and frequency domain location information occupied by the CSI-RS resource, sequence information, and the like, which is basically the same as the CSI-RS configuration method in multiple input multiple output (MIMO). Such CSI-RS is also referred to as mobility CSI-RS (CSI-RS for mobility).

[0046] 2. RRM measurement based on CSI-RS for mobility

[0047] ​Generally, compared with SSB-based RRM measurement, the advantages of CSI-RS-based RRM measurement for mobility include: 1) the bandwidth of SSB is not variable, while the bandwidth of CSI-RS is variable; 2) the configuration of SSB is relatively fixed, which is reused for cell selection / access function of terminal, generally broadcast type transmission, used for idle state camping and network search; CSI-RS can be independently configured for some cells, and the beam can also be flexibly configured, which is convenient for network to coordinate resources.

[0048] 3. Synchronization information of CSI-RS for mobility and quasi co-location (QCL) relationship

[0049] Generally, in the configuration of CSI-RS for mobility, a parameter associatedSSB is included, which is used to indicate the SSB for obtaining the timing when performing CSI-RS measurement. The parameter associatedSSB further includes two sub-parameters of SSB-Index and isQuasiColocated. The parameter group is configured per resource, and can not be configured.

[0050] If the associatedSSB is not configured, there are two possibilities: 1) if the parameter refServCellIndex is configured, the terminal obtains the timing based on the cell indicated by the parameter, and performs measurement. This parameter is configured per cell (of resources); 2) if the parameter refServCellIndex is not configured, the terminal performs measurement of CSI-RS based on the timing of the current primary cell Pcell.

[0051] If the associatedSSB is configured, the terminal obtains the timing based on the SSB corresponding to the SSB-Index, and performs measurement of CSI-RS based on the timing. The SSB is the SSB in the cell indicated by the cellId parameter corresponding to the CSI-RS. If the SSB cannot be detected, the terminal does not need to perform measurement of CSI-RS. The terminal considers that the CSI-RS and the SSB should be QCL-D.

Furthermore, "or" in this application indicates at least one of the connected objects. For example, the scope of protection for "A or B" covers at least three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. In addition, the terms "A and / or B," "at least one of A and B," and "at least one of A or B" also cover at least the above three scenarios. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0054] The term "instruction" in this application can be either a direct instruction (or explicit instruction) or an indirect instruction (or implicit instruction).

[0059] The mobility measurement method, apparatus and related device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings and some embodiments and application scenarios.

[0060] The execution subject of the mobility measurement method provided by the embodiments of the present application can be a mobility measurement apparatus, or a terminal, or a function module or entity in the terminal, or a network device, or a function module or entity in the network device. In the embodiments of the present application, the terminal and the network device are taken as examples to execute the mobility measurement method, and the mobility measurement method provided by the embodiments of the present application is described.

[0061] FIG. 2 shows a flow diagram of a mobility measurement method provided by an embodiment of the present application. As shown in FIG. 2, the mobility measurement method provided by an embodiment of the present application can include the following steps 101 and 102.

[0062] Step 101: The terminal acquires a first mobility measurement request.

[0063] In the embodiments of the present application, the first mobility measurement request is used to request to perform mobility measurement on a first reference signal, and the first reference signal is used for at least one of the following: positioning measurement, perception measurement.

[0064] In some embodiments of the present application, in the case where the first reference signal is used for positioning the terminal, the first reference signal can include a positioning reference signal (PRS). The PRS can include at least one of a downlink PRS and an uplink PRS. Of course, the first reference signal can also include other reference signals, which are not limited in the embodiments of the present application.

[0065] In some embodiments of the present application, in the case where the first reference signal is used for perceiving a perception target, the first reference signal can include a perception signal. Of course, the first reference signal can also include other reference signals, which are not limited in the embodiments of the present application.

[0066] In some embodiments of the present application, the terminal can receive a first mobility measurement request from a first network device, or receive a first mobility measurement request from a second network device. The first network device can be an access network device, such as a base station. The second network device can be a core network device, such as a Location Management Function (LMF) network element. Of course, the first network device can also be other access network devices, and the second network device can also be other core network devices, which are not limited in the embodiments of the present application.

[0067] In some embodiments of the present application, the first reference signal is configured in N time windows, which satisfy at least one of the following:

[0068] The length of each time window is less than or equal to a second threshold;

[0069] N is greater than or equal to 1;

[0070] N is less than or equal to a third threshold.

[0071] In some examples, in the case that the first reference signal belongs to Frequency Range (FR) 2, N = 1; in the case that the first reference signal belongs to FR1, N is greater than or equal to 1, and / or N is less than or equal to 2.

[0072] As can be seen, since the length of each time window in the N time windows is less than or equal to the second threshold, this can avoid the case that the length of the N time windows is too long, resulting in a longer measurement time for the terminal to perform mobility measurement, so as to reduce the power consumption of the terminal; and since the number N of the N time windows can be greater than or equal to 1, and / or less than or equal to the third threshold, this can enable the terminal to concentrate on multiple mobility measurements, so as to improve the accuracy of the mobility measurement results obtained by measurement.

[0073] Step 102, the terminal performs mobility measurement on the first reference signal according to the first mobility measurement request.

[0074] In the embodiments of the present application, the first reference signal is used for at least one of the following: positioning measurement, perception measurement. The positioning measurement can realize positioning of the terminal, and the perception measurement can realize perception of a perception target.

[0075] Optionally, after receiving the first mobility measurement request, the terminal can perform mobility measurement in the process of performing positioning measurement or perception measurement on the first reference signal.

[0076] In some embodiments of the present application, as shown in FIG. 3, before step 101, the mobility measurement method provided by the embodiments of the present application can further include steps 201 and 202 in combination with FIG. 2.

[0077] Step 201: The terminal receives first configuration information.

[0078] In the embodiments of the present application, the first configuration information is used for configuring the use of the first reference signal, and the use includes at least one of the following: positioning measurement, perception measurement.

[0079] In some examples, the terminal can be requested to perform mobility measurement on the first reference signal corresponding to the subset or the whole set of the first configuration information through a first mobility measurement request.

[0080] It should be noted that in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is part of the B configuration or the whole B configuration; or, the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or, the first reference signal indicated by the A configuration is within the range of the first reference signal indicated by the B configuration.

[0081] In some embodiments of the present application, the first configuration information can include assistance information, and the assistance information includes a plurality of configuration information of a plurality of reference signals of a plurality of cells and / or a plurality of transmission / reception points (TRPs), each configuration information being used for configuring the use of a reference signal associated with a cell and / or a TRP.

[0082] The assistance information can be referred to as positioning assistance information or perception assistance information, which is not limited in the embodiments of the present application. In the case that the terminal receives the assistance information from the first network device (such as a base station), the assistance information can be PosSystemInformation, and optionally, the assistance information is broadcast assistance information; in the case that the terminal receives the assistance information from the second network device (such as a location server), the assistance information can be NR-DL-PRS-AssistanceData, and optionally, the assistance information is unicast assistance information.

[0083] Optionally, the first configuration information can be broadcasted, or groupcasted, or unicasted by the sending device.

[0084] It can be understood that, since the terminal can obtain the configuration information of the reference signals of the plurality of cells and / or the plurality of TRPs through the above-mentioned assistance information before obtaining the first mobility measurement request, the terminal can perform mobility measurement on the first reference signal according to the first mobility measurement request and the configuration information of the first reference signal in the plurality of configuration information without receiving other configuration information in the subsequent steps.

[0085] In some embodiments of the present application, the terminal can receive the first configuration information from the first network device, or the terminal can receive the first configuration information from the second network device.

[0086] In some embodiments of the present application, the terminal can receive the first configuration information in the case of positioning and / or sensing of the terminal.

[0087] Optionally, the terminal receiving the first configuration information can also be after receiving the first mobility measurement request, or simultaneously receiving (such as in different messages at the same time, or in the same message at the same time) the first mobility measurement request.

[0088] Optionally, the terminal receiving the first configuration information and receiving the first mobility measurement request have no direct time sequence.

[0089] Optionally, the configuration information of the first reference signal for performing mobility measurement (such as the second configuration information) is a subset or the whole set of the first configuration information; and the first reference signal for performing mobility measurement is a subset or the whole set of the first reference signal configured in the first configuration information.

[0090] It should be noted that, in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is part of the B configuration or all of the B configuration; or the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or the first reference signal indicated by the A configuration is not more than the range of the first reference signal indicated by the B configuration.

[0091] In step 202, the terminal performs at least one of the following on the first reference signal according to the first configuration information: positioning measurement, sensing measurement.

[0092] In some embodiments of the present application, in the case where the first configuration information configures the purpose of the first reference signal as positioning measurement, the terminal can perform positioning measurement on the first reference signal according to the first configuration information. In the case where the first configuration information configures the purpose of the first reference signal as sensing measurement, the terminal can perform sensing measurement on the first reference signal according to the first configuration information.

[0093] Therefore, the terminal can determine the first reference signal according to the first mobility measurement request and the first configuration information after receiving the first configuration information, without receiving other configuration information, so that the resources occupied by the terminal for receiving the other configuration information can be saved; and the first configuration information configures the use of the first reference signal as a use different from the mobility measurement, so that the terminal can perform the mobility measurement on the first reference signal while performing the positioning measurement and / or the perception measurement on the first reference signal, without the terminal additionally performing the mobility measurement on the SSB, so that the number of times of measurement of the terminal can be reduced; and therefore, the resources of the terminal can be saved, and the power consumption of the terminal can be reduced.

[0094] In some embodiments of the present application, in the case that the above-mentioned first configuration information does not include the above-mentioned auxiliary information, the network device (for example, the first network device or the second network device) can further send the auxiliary information to the terminal before the above-mentioned step 201.

[0095] In a possible implementation of the present application, the above-mentioned first mobility measurement request includes at least one of the following:

[0096] an identifier of at least one frequency layer associated with the first reference signal;

[0097] an identifier of at least one cell associated with the first reference signal;

[0100] an identifier of at least one resource associated with the first reference signal;

[0101] second configuration information;

[0102] a response time requirement;

[0103] a mobility request identifier.

[0104] In some embodiments of the present application, the identifier of each frequency layer can include at least one of the following: an entry of the frequency layer in a frequency layer entry list, a frequency point (for example, a reference point A (pointA)) of each frequency layer, and an ID of each frequency layer. Of course, the identifier of each frequency layer can also include other identifiers, which are not limited in the embodiments of the present application.

[0105] In some embodiments of the present application, the identity of each cell can include at least one of the following: a physical cell identity (PCI), a cell global identifier (CGI), an absolute radio frequency channel number (ARFCN), an entry indication of each cell in a frequency layer inner cell entry list. Of course, the identity of each cell can also include other identities, which are not limited in the embodiments of the present application.

[0106] In some embodiments of the present application, the identity of each TRP can include at least one of the following: an ID of a transmitted reference signal of each TRP, an ID of each TRP, an entry indication of each TRP in a TRP entry list in a frequency layer.

[0107] In some embodiments of the present application, the identity of each resource set can include at least one of the following: an identity of a corresponding TRP of each resource set, an ID of each resource set, an entry indication of each resource set in a resource set entry list in a TRP.

[0108] In some embodiments of the present application, the identity of each resource can include at least one of the following: an identity of a corresponding TRP of each resource, an identity of a resource set to which each resource belongs, an identity of each resource, an entry indication of each resource in a resource entry list in a resource set, an entry indication of each resource in a resource entry list in a TRP.

[0109] Optionally, the configuration of at least one of the frequency layer, the cell, the TRP, the resource set, and the resource associated with the first reference signal in the above indication is from the first configuration information. The terminal can perform mobility measurement on the first reference signal associated with the 'identity' according to the identity information contained in the first mobility measurement request.

[0110] In some embodiments of the present application, in the case where the terminal obtains a plurality of configuration information of reference signals of a plurality of cells and / or a plurality of TRPs through the above-mentioned assistance information, at least one of the following is included in the first mobility measurement request: an identity of at least one frequency layer associated with the first reference signal, an identity of at least one cell associated with the first reference signal, an identity of at least one TRP associated with the first reference signal, an identity of at least one resource set associated with the first reference signal, and an identity of at least one resource associated with the first reference signal.

[0111] In the embodiments of the present application, the second configuration information is used to determine the first reference signal.

[0112] It can be understood that the second configuration information is at least part of the plurality of configuration information of the reference signal of the plurality of cells and / or the plurality of TRPs, and the second configuration information can be at least part of the first configuration information.

[0113] In some examples, the second configuration information is used to determine the first reference signal for mobility measurement.

[0114] Optionally, the second configuration information is a subset or the whole set of the configuration (or indication) of the first configuration information; or the first reference signal configured by the second configuration information belongs to a subset or the whole set of the first reference signal configured by the first configuration information.

[0115] It should be noted that in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is part of the configuration or all of the configuration of the B configuration; or the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or the first reference signal indicated by the A configuration does not exceed the range of the first reference signal indicated by the B configuration.

[0116] In some embodiments of the present application, the second configuration information includes at least one sub-configuration information, and each sub-configuration information is used to configure a terminal to perform mobility measurement on a target object associated with the first reference signal; wherein each target object includes at least one of the following: at least one measurement object (Measurement Object) and at least one frequency layer (Frequency Layer).

[0117] In some embodiments of the present application, each sub-configuration information can include or correspond to one measurement object or one frequency layer.

[0118] In one example, each measurement object can correspond to one frequency layer, or one center frequency point, or one reference point A. Each frequency layer can be associated with the ID of one measurement object.

[0119] In another example, each measurement object can correspond to at least one frequency layer, or at least one center frequency point, or at least one reference point A.

[0120] In some embodiments of the present application, in the case where each target object includes at least one measurement object, the second configuration information further includes the identification of each frequency layer corresponding to each measurement object.

[0121] Optionally, the first reference signal contained in one frequency layer or one measurement object satisfies at least one of the following characteristics:

[0122] the same center frequency point;

[0123] the same reference point A;

[0124] the same bandwidth;

[0125] the same subcarrier spacing;

[0126] the same frequency domain density;

[0127] the same period;

[0128] The first reference signal is configured in N time windows.

[0129] Optionally, the N time windows satisfy at least one of the following:

[0130] The length of each time window is less than or equal to a second threshold;

[0131] N is greater than or equal to 1;

[0132] N is less than or equal to a third threshold.

[0133] In some examples, in a case where the first reference signal belongs to Frequency Range (FR) 2, N = 1; in a case where the first reference signal belongs to FR1, N is greater than or equal to 1, and / or N is less than or equal to 2.

[0134] It should be noted that the description of the identification of the at least one frequency layer can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated.

[0135] As can be seen, since each sub-configuration information included in the second configuration information is used to configure the terminal to perform mobility measurement on a target object associated with the first reference signal, the terminal can perform mobility measurement on each target object respectively according to each sub-configuration information, so as to accurately perform mobility measurement on the first reference signal.

[0136] Optionally, if one sub-configuration information is included in the second configuration information, the sub-configuration information of the second configuration information can be equivalent to the second configuration information.

[0137] In some embodiments of the present application, in a case where each target object includes at least one frequency layer, or each target object includes at least one measurement target and each measurement target corresponds to at least one frequency layer, the second configuration information further includes at least one of the following:

[0138] a first bitmap, used to indicate the at least one frequency layer;

[0139] an identification of the at least one frequency layer.

[0140] In some embodiments of the present application, the first bitmap can include a plurality of bits, the number of the plurality of bits can be the same as the number of frequency domain layers included in the frequency layer list, each bit corresponds to a frequency layer (for example, each bit corresponds to each entry in the frequency layer list one by one), and the bit value of each bit can be 0 or 1. The value of at least one bit in the plurality of bits is 1, and the at least one bit corresponds to the at least one frequency layer one by one.

[0141] The frequency layer list can be:

[0142] nr-DL-PRS-AssistanceDataList SEQUENCE(SIZE(1..nrMaxFreqLayers))OF

[0143] NR-DL-PRS-AssistanceDataPerFreq.

[0144] Wherein, nr-DL-PRS-AssistanceDataList is a frequency layer list, nrMaxFreqLayers represents the number of frequency layers, or the size of the list; AssistanceDataPerFreq is a configuration of a frequency layer in the frequency layer list.

[0145] It can be understood that if the bit value of a bit is 1, it means that the mobility measurement is performed on the frequency layer corresponding to the bit, or the frequency layer corresponding to the bit can be used for mobility measurement.

[0146] It should be noted that the description of the identification of the at least one frequency layer can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated.

[0147] Therefore, the terminal can accurately perform mobility measurement on the at least one frequency layer.

[0148] In some embodiments of the present application, each sub-configuration information includes at least one of the following:

[0149] Cell indication information for indicating at least one cell for mobility measurement;

[0150] TRP indication information, used for indicating at least one TRP for mobility measurement;

[0151] Resource set indication information, used for indicating at least one resource set for mobility measurement;

[0152] Resource indication information, used for indicating at least one resource for mobility measurement;

[0153] Time domain resource indication information, used for indicating at least part of time domain resources in at least one resource for mobility measurement;

[0154] Repeated transmission resource indication information, used for indicating at least part of repeated transmission resources in at least one resource for mobility measurement;

[0155] Measurement indication information, used for indicating the terminal to perform mobility measurement on the first reference signal within a mobility measurement window;

[0156] Frequency domain range indication information, used for indicating a frequency domain range for mobility measurement;

[0157] The first parameter related to mobility measurement.

[0158] Optionally, since each sub-configuration information can correspond to one measurement target or one frequency layer, or each sub-configuration information is used for configuring the terminal to perform mobility measurement on a target object associated with the first reference signal, the sub-configuration information includes at least one of the above information (such as cell, TRP, resource set, etc.), and it can be understood that one measurement target or one frequency layer or one target object includes at least one of the above information.

[0159] In some embodiments of the present application, the above-mentioned cell indication information includes at least one of the following:

[0160] An identifier of at least one cell;

[0161] Indication information of a TRP associated with each cell in the at least one cell.

[0162] It should be noted that the description of the identifier of the at least one cell can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0163] In some embodiments of the present application, the above-mentioned TRP indication information includes at least one of the following:

[0164] A second bitmap, used for indicating a TRP associated with each cell in the at least one cell;

[0165] An identifier of a TRP associated with each cell in the at least one cell.

[0166] In some embodiments of the present application, the second bitmap can include a plurality of bits, the number of the plurality of bits can be the same as the number of TRPs included in at least one measurement target or at least one frequency layer corresponding to one sub-configuration information (for example, the TRPs included in at least one measurement target or at least one frequency layer corresponding to one sub-configuration information are the TRPs in the TRP list). Each bit of the plurality of bits corresponds to one of the TRPs included in the at least one measurement target or at least one frequency layer (for example, each bit corresponds to each entry in the TRP list one by one), and the value of each bit can be 0 or 1. The value of at least one bit of the plurality of bits is 1, and the at least one bit corresponds to one-to-one to the TRP associated with at least one cell.

[0167] The TRP list can be:

[0168] nr-DL-PRS-AssistanceDataPerFreq SEQUENCE(SIZE(1..nrMaxTRPsPerFreq))OF

[0169] NR-DL-PRS-AssistanceDataPerTRP

[0170] nr-DL-PRS-AssistanceDataPerFreq is the TRP list, nrMaxTRPsPerFreq represents the number of TRPs included in one frequency layer, or the list size; and AssistanceDataPerTRP is the configuration of one TRP in the TRP list.

[0171] It can be understood that if the value of one bit is 1, it means that the mobility measurement is to be performed on the TRP corresponding to the one bit.

[0172] As can be seen, since the embodiments of the present application specify the specific content of the TRP indication information, the terminal can accurately determine each TRP to be measured according to the specific content, and therefore the terminal can accurately measure the first reference signal sent by each TRP.

[0173] As can be seen, since the embodiments of the present application specify the specific content included in the cell indication information, the terminal can accurately determine at least one cell to be measured and / or at least one first TRP sending the first reference signal in the at least one cell to be measured according to the specific content, and therefore the terminal can accurately measure the first reference signal of the at least one cell and / or the first reference signal sent by the at least one TRP associated with the at least one cell.

[0174] In some embodiments of the present application, the resource set indication information comprises at least one of the following:

[0175] a third bitmap, used to indicate the at least one resource set;

[0176] an identity of the at least one resource set.

[0177] In some embodiments of the present application, the third bitmap can comprise a plurality of bits, the number of the plurality of bits can be the same as the number of resource sets contained in the at least one measurement target or the at least one frequency layer corresponding to one sub-configuration information (e.g., the resource sets in the resource set list contained in the at least one measurement target or the at least one frequency layer corresponding to one sub-configuration information). Each bit of the plurality of bits corresponds to one resource set of the resource sets contained in the at least one measurement target or the at least one frequency layer (e.g., each bit corresponds to each entry in the resource set list one by one), and the value of each bit can be 0 or 1. The value of at least one bit of the plurality of bits is 1, and the at least one bit corresponds to the at least one resource set one by one.

[0178] The resource set list can be:

[0179] nr-DL-PRS-ResourceSetList SEQUENCE(SIZE(1..nrMaxSetsPerTrpPerFreqLayer)) OF

[0180] NR-DL-PRS-ResourceSet

[0181] Wherein, nr-DL-PRS-ResourceSetList is a resource set list, nrMaxSetsPerTrpPerFreqLayer represents the number of resource sets contained in one TRP, or the list size; and NR-DL-PRS-ResourceSet is a resource set configuration in the resource set list.

[0182] It should be noted that the identity of the at least one resource set can be described in detail in the above embodiments, and the embodiments of the present application will not be repeated here.

[0183] As can be seen, since the embodiments of the present application specify the specific content included in the resource set indication information, the terminal can accurately determine the at least one resource set to be measured according to the specific content, and thus the terminal can accurately measure the at least one resource set.

[0184] In some embodiments of the present application, the resource indication information comprises at least one of the following:

[0185] a fourth bitmap, used for indicating the at least one resource;

[0186] an identity of the at least one resource.

[0187] In some embodiments of the present application, the fourth bitmap can comprise a plurality of bits, and the number of the plurality of bits can be the same as the number of resources contained in the at least one measurement target or the at least one frequency layer corresponding to one sub-configuration information (e.g., the resources in the resource list contained in the at least one measurement target or the at least one frequency layer corresponding to one sub-configuration information). Each bit of the plurality of bits corresponds to one resource of the resources contained in the at least one measurement target or the at least one frequency layer (e.g., each bit corresponds to each entry in the resource list one by one), and the value of each bit can be 0 or 1. The value of at least one bit of the plurality of bits is 1, and the at least one bit corresponds to the at least one resource one by one.

[0188] The resource list can be:

[0189] dl-PRS-ResourceList SEQUENCE(SIZE(1..nrMaxResourcesPerSet))OF

[0190] NR-DL-PRS-Resource,

[0191] The nr-DL-PRS-ResourceList is the resource list, the nrMaxResourcesPerSet represents the number of resources contained in one resource set, or the list size, and the NR-DL-PRS-Resource is the configuration of one resource set in the resource list.

[0192] It should be noted that the identity of the at least one resource can be described in detail in the above embodiments, and the present application will not repeat it here.

[0193] As can be seen, since the present application specifies the specific content included in the resource indication information, the terminal can accurately determine the at least one resource to be measured according to the specific content, and thus the terminal can accurately measure the at least one resource.

[0194] In some embodiments of the present application, the at least part of the time domain resources can include at least one of the following: a symbol, a slot, a subframe, and the like.

[0195] It can be understood that, since the mobility measurement is different from the regulation requirement of the conventional bit measurement and / or the sensing measurement, the terminal can not need to measure the complete first reference signal, for example, the terminal can only need to measure part of the at least one TRP, part of the at least one resource set, part of the at least one resource, part of the at least one time domain resource (for example, a symbol), and part of the bandwidth in the frequency domain resource for the mobility measurement. Therefore, in an example, the terminal can only measure part of the at least one time domain resource, and then obtain the mobility measurement result.

[0196] In some embodiments of the present application, the time domain resource indication information includes at least one of the following:

[0197] A fifth bitmap, used to indicate at least part of the time domain resources.

[0198] An index of the at least part of the time domain resources.

[0199] In some embodiments of the present application, the fifth bitmap can indicate an index of each time domain resource in the at least part of the time domain resources; or the fifth bitmap can indicate an index of each resource where each time domain resource in the at least part of the time domain resources is located; or the fifth bitmap can indicate a number of the at least part of the time domain resources.

[0200] In some examples, in the case where the fifth bitmap indicates an index of each resource where each time domain resource in the at least part of the time domain resources is located, the terminal can determine the i-th time domain resource of each resource as the each time domain resource. i is a positive integer.

[0201] For example, in the case where the fifth bitmap indicates an index of each resource where each symbol in the at least part of the time domain resources (for example, a symbol) is located, the terminal can determine the 1st symbol of each resource as each symbol in the at least part of the time domain resources.

[0202] In some embodiments of the present application, the at least part of the time domain resources includes at least two time units, and the at least two time units are associated with at least two resource elements REs having the same frequency domain location.

[0203] The time unit can be any one of the following: a symbol, a slot, a subframe, and the like.

[0204] In some embodiments of the present application, the at least two time units can be used for the frequency domain related large-scale parameter.

[0205] Thus, it can be known that, since the embodiment of the present application specifies the specific content included in the time domain resource indication information, the terminal can accurately determine the at least part of the time domain resources to be measured according to the specific content, and thus the terminal can accurately measure the at least part of the time domain resources.

[0206] In some embodiments of the present application, the repeated transmission can include at least one of the following: intra-slot repetition, inter-slot repetition, and all of intra-slot and inter-slot repetition.

[0207] It can be understood that, in an example, the terminal can measure only part of the repeated transmission resources in the at least one resource, and thus obtain the mobility measurement result.

[0208] In some embodiments of the present application, the number of the at least part of the repeated transmission resources is at least one, and each resource includes one repeated transmission resource.

[0209] It can be understood that, for one resource for which the mobility measurement is performed, the terminal only needs to measure one repeated transmission resource to obtain the mobility measurement result.

[0210] In the embodiment of the present application, each target object corresponds to one measurement indication information, and it can be understood that each target object is configured with one mobility measurement window.

[0211] In some embodiments of the present application, the mobility measurement window can reuse the SSB measurement time configuration (SSB Measurement Time Configuration, SMTC), for example, the SMTC is used as the mobility measurement window, and the mobility measurement is performed in the SMTC.

[0212] In some embodiments of the present application, the mobility measurement window can be referred to as a positioning reference signal measurement time configuration (PRS Measurement Time Configuration, PMTC). Of course, the mobility measurement window can also be referred to as other names, and the embodiment of the present application does not limit this.

[0213] In some embodiments of the present application, the terminal does not expect to perform mobility measurement on the first reference signal outside the mobility measurement window.

[0214] In some embodiments of the present application, the timing of the mobility measurement window can be a serving cell of the terminal. For example, the serving cell can be a default primary cell (Pcell), or a serving cell sending the second configuration information or the first mobility measurement request, or a serving cell indicated by the network device.

[0215] In some embodiments of the present application, the measurement indication information can include at least one of the following:

[0216] an identifier of the mobility measurement window;

[0217] a period of the mobility measurement window;

[0218] a duration of the mobility measurement window;

[0219] a start time or offset of the mobility measurement window.

[0220] The start time or offset includes at least one of the following: a system frame number (SFN), a slot offset, and a symbol offset.

[0221] In some embodiments of the present application, the mobility measurement window can be configured simultaneously with a measurement gap or a reference signal processing window (such as a positioning reference signal processing window (PPW)) configured for positioning measurement and / or perception measurement.

[0222] In an example, if a measurement gap or a reference signal processing window is configured for mobility measurement, the terminal does not expect the mobility measurement window to exceed the measurement gap or the reference signal processing window.

[0223] In some embodiments of the present application, the frequency domain range can be smaller than the frequency domain range of the first reference signal actually transmitted; or smaller than the frequency domain range of the first reference signal configured in positioning or perception.

[0224] In some embodiments of the present application, the frequency domain range indication information includes at least one of the following:

[0225] frequency domain position indication information, used to indicate a first starting frequency domain position of the frequency domain range for mobility measurement;

[0226] bandwidth indication information, used to indicate a first bandwidth of the frequency domain range for mobility measurement.

[0227] Therefore, the terminal can accurately determine the frequency domain range for mobility measurement according to the specific content of the frequency domain range indication information, and thus can accurately perform mobility measurement on the frequency domain range.

[0228] In some embodiments of the present application, the first parameter includes at least one of the following:

[0229] The first measurement type indication information is used to indicate a measurement manner for performing mobility measurement.

[0230] The first threshold is a threshold used for screening out a mobility measurement result from a measurement result obtained by performing mobility measurement, the mobility measurement result being a measurement result of performing mobility measurement on the first reference signal.

[0231] The first quantity is a maximum number of measurement results allowed to be processed simultaneously.

[0232] The first filter coefficient is a filter coefficient used for performing mobility measurement.

[0233] The first measurement type indication information is used to indicate a measurement manner for performing mobility measurement.

[0234] In some embodiments of the present application, the measurement quantity of the required measurement can include at least one of the following: layer L3-Reference Signal Received Power (RSRP), L3-Reference Signal Received Quality (RSRQ), L3-Signal To Interference Plus Noise Ratio (SINR), and L3-Received Signal Strength Indication (RSSI).

[0235] It can be understood that the first threshold can be understood as a measurement screening threshold. Since mobility measurement on the first reference signal can obtain multiple measurement results, the terminal can use the first threshold to screen the multiple measurement results, for example, determine the measurement result with a measurement value greater than or equal to the first threshold (or less than or equal to the first threshold) in the multiple measurement results as a mobility measurement result.

[0236] In some embodiments of the present application, the first quantity can be specifically a maximum number of measurement results allowed to be used for linear average calculation.

[0237] In the embodiments of the present application, the measurement manner includes at least one of a cell-level measurement manner and a beam-level measurement manner. The cell-level measurement manner is a manner of performing mobility measurement on the first reference signal according to a cell granularity. The beam-level measurement is a manner of performing mobility measurement on the first reference signal according to a beam granularity.

[0238] Therefore, the terminal can accurately perform measurement on the first reference signal according to the specific content included in the first parameter.

[0239] In the embodiments of the present application, the response time requirement is used to indicate the latest time for the terminal to feed back the mobility measurement result, which is the measurement result of the mobility measurement on the first reference signal.

[0240] In the embodiments of the present application, the mobility request identifier is used to indicate that the terminal performs mobility measurement on the first reference signal.

[0241] Therefore, the terminal can accurately perform measurement on the first reference signal according to the specific content included in the first mobility measurement request.

[0242] In some embodiments of the present application, in the case where at least one of the following is included in the first mobility measurement request: an identifier of at least one frequency layer associated with the first reference signal, an identifier of at least one cell associated with the first reference signal, an identifier of at least one transmission and reception point (TRP) associated with the first reference signal, an identifier of at least one resource set associated with the first reference signal, and an identifier of at least one resource associated with the first reference signal, if the first configuration information includes multiple configuration information of multiple reference signals of multiple cells and / or multiple TRPs or the terminal receives assistance information from the first network device or the second network device, the terminal can determine at least one of the at least one frequency layer, the identifier of the at least one cell, the at least one TRP, the at least one resource set, and the at least one resource from the multiple configuration information according to at least one of the identifier of the at least one frequency layer, the identifier of the at least one cell, the at least one TRP, the at least one resource set, and the at least one resource associated with the first reference signal, so that the terminal can perform mobility measurement on at least one of the at least one frequency layer, the identifier of the at least one cell, the at least one TRP, the at least one resource set, and the at least one resource.

[0243] In some embodiments of the present application, in the case that the second configuration information is included in the first mobility measurement request, the terminal can directly determine at least one of the at least one frequency layer associated with the first reference signal, the at least one cell associated with the first reference signal, the at least one TRP associated with the first reference signal, the at least one resource set associated with the first reference signal, and the at least one resource associated with the first reference signal according to the second configuration information, so that the terminal can perform mobility measurement on at least one of the at least one frequency layer, the identification of the at least one cell, the at least one TRP, the at least one resource set, and the at least one resource.

[0244] In some embodiments of the present application, in the case that the second configuration information is not included in the first mobility measurement request, as shown in FIG. 4, before the step 101, the mobility measurement method provided by the embodiments of the present application can further include the following step 203, and the step 102 can be implemented by the following step 102a.

[0245] The step 203 includes that the terminal receives the second configuration information.

[0246] It should be noted that the embodiments of the present application do not limit the execution order of the step 203 and the step 201; in one example, the terminal can execute the step 201 first and then execute the step 203; in another example, the terminal can execute the step 203 first and then execute the step 201; in yet another example, the terminal can execute the step 201 while executing the step 203.

[0247] In the embodiments of the present application, the second configuration information is used to determine the first reference signal.

[0248] In some examples, the second configuration information is used to determine the first reference signal for mobility measurement.

[0249] It should be noted that the specific content of the second configuration information can be referred to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0250] The step 102a includes that the terminal performs mobility measurement on the first reference signal according to the first mobility measurement request and the second configuration information.

[0251] In other words, the terminal performs measurement on the first reference signal configured by the second configuration information according to the first mobility measurement request.

[0252] Therefore, the terminal can accurately determine the first reference signal according to the second configuration information and accurately perform the mobility measurement on the first reference signal according to the first mobility measurement request, so that an accurate mobility measurement result can be obtained.

[0253] In some embodiments of the present application, the first reference signal indicated by the first mobility measurement request or the second configuration information is a subset or the whole set of the first reference signal indicated by the first configuration information; wherein the first configuration information is used for configuring the use of the first reference signal, and the use includes at least one of the following: positioning measurement, sensing measurement; and the second configuration information is used for determining the first reference signal.

[0254] It should be noted that in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is a part of the B configuration or the whole B configuration; or the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or the first reference signal indicated by the A configuration is within the range of the first reference signal indicated by the B configuration.

[0255] Therefore, the first reference signal indicated by the first mobility measurement request or the second configuration information can be a subset or the whole set of the first reference signal indicated by the first configuration information, so that after receiving the first configuration information, the terminal can determine the first reference signal without receiving other configuration information, thereby saving the resources occupied by receiving other configuration information.

[0256] Optionally, the terminal receiving the second configuration information can be decoupled from receiving the first mobility measurement request, so that the first mobility measurement request can not include the second configuration information. For example, the first mobility measurement request includes at least one of the following: response time requirement; mobility request identifier.

[0257] Optionally, the terminal performing the mobility measurement on the first reference signal according to the first mobility measurement request and the second configuration information includes: the configuration of the first reference signal for performing the mobility measurement belongs to a subset or the whole set of the second configuration information; or the first reference signal for performing the mobility measurement belongs to a subset or the whole set of the first reference signal configured in the second configuration information.

[0258] It should be noted that in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is a part of the B configuration or the whole B configuration; or the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or the first reference signal indicated by the A configuration is within the range of the first reference signal indicated by the B configuration.

[0259] Optionally, the first mobility measurement request includes an indication of a subset of the second configuration information.

[0260] Optionally, in another possible implementation manner of the present application, the first mobility measurement request includes at least one of the following:

[0261] fourth configuration information;

[0262] a response time requirement;

[0263] a mobility request identifier;

[0264] Optionally, the fourth configuration information is an indication that the first mobility measurement request includes a subset of the second configuration information. Alternatively, the first reference signal indicated in the fourth configuration information is a subset of the first reference signal indicated in the second configuration information.

[0265] In some embodiments of the present application, in a case where each of the sub-configuration information includes frequency domain range indication information, and the frequency domain range indication information includes frequency domain position indication information and bandwidth indication information, the step 102 can be implemented by the following step 102b.

[0266] The step 102b includes: performing, by the terminal, the mobility measurement on the first reference signal in the first frequency domain range.

[0267] In the embodiments of the present application, the first frequency domain range satisfies at least one of the following:

[0268] a center frequency point of the first reference signal as a center, and a bandwidth same as the first bandwidth;

[0269] a first starting frequency domain position as a starting point, and a bandwidth same as the first bandwidth;

[0270] a starting frequency domain position of the first reference signal as a starting point, and a bandwidth same as the first bandwidth.

[0271] Therefore, the terminal can accurately perform the mobility measurement on the first reference signal in the first frequency domain range according to the regulation.

[0272] In some embodiments of the present application, in a case where the terminal starts to perform the positioning measurement and / or the perception measurement, the terminal can send a first notification to the network device (for example, the first network device or the second network device), the first notification being used to inform that the terminal starts to perform the positioning measurement and / or the perception measurement, and the first notification being used to trigger the first network device or the second network device to send the first mobility measurement request to the terminal.

[0273] It can be understood that, since the terminal can indicate the first network device or the second network device by the first notification in a case that the terminal starts to perform the positioning measurement and / or the perception measurement, the first network device or the second network device can send the first mobility measurement request to the terminal, and then the terminal can perform the mobility measurement on the first reference signal, so that the terminal can perform the mobility measurement on the first reference signal while performing the positioning measurement and / or the perception measurement without the terminal additionally performing the mobility measurement on the SSB, and thus the number of measurements performed by the terminal can be reduced.

[0274] In some embodiments of the present application, in a case that the terminal stops performing the positioning measurement and / or the perception measurement, the terminal can send a second notification to the network device (for example, the first network device or the second network device), the second notification being used to inform the terminal to stop performing the positioning measurement and / or the perception measurement, and the second notification being used to trigger the first network device or the second network device to send a second mobility measurement request to the terminal, the second mobility measurement request being used to request the terminal to stop performing the mobility measurement on the first reference signal.

[0275] It can be understood that, since the terminal can indicate the first network device or the second network device by the second notification in a case that the terminal stops performing the positioning measurement and / or the perception measurement, the first network device or the second network device can send the second mobility measurement request to the terminal, and then the terminal can stop performing the mobility measurement on the first reference signal, so that the terminal can stop performing the mobility measurement on the first reference signal while stopping performing the positioning measurement and / or the perception measurement, and thus the number of measurements performed by the terminal can be reduced.

[0276] In some embodiments of the present application, as shown in FIG. 5, after the step 102, the mobility measurement method provided by the embodiments of the present application can further include the following step 103 in combination with FIG. 2.

[0277] The step 103 includes that the terminal reports the mobility measurement result.

[0278] In the embodiments of the present application, the mobility measurement result is a measurement result of the mobility measurement on the first reference signal.

[0279] In some embodiments of the present application, the terminal can report the mobility measurement result to the first network device, or the terminal can report the mobility measurement result to the second network device.

[0280] In a case where the terminal receives a first mobility measurement request from the first network device, the terminal can report a mobility measurement result to the first network device. In a case where the terminal receives a first mobility measurement request from the second network device, the terminal can report a mobility measurement result to the second network device.

[0281] As such, since the terminal can also report a mobility measurement result, the network device can accurately perform mobility management on the terminal according to the mobility measurement result, and thus the communication quality of the terminal can be improved.

[0282] In some embodiments of the present application, the mobility measurement result includes at least one of the following:

[0283] at least one first measurement result, each first measurement result being a measurement result of a cell associated with the first reference signal;

[0284] at least one second measurement result, each second measurement result being a measurement result of at least one beam corresponding to a cell associated with the first reference signal.

[0285] It should be noted that the "at least one beam corresponding to a cell" can be understood as a beam transmitted by a TRP included in the cell.

[0286] In embodiments of the present application, the at least one first measurement result is measured by using a cell-level measurement method, and the at least one second measurement result is measured by using a beam-level measurement method. The measurement method includes at least one of the following: a cell-level measurement method, and a beam-level measurement method. The cell-level measurement method is a method of performing mobility measurement on the first reference signal according to a cell granularity, and the beam-level measurement method is a method of performing mobility measurement on the first reference signal according to a beam granularity.

[0287] In some embodiments of the present application, in a case where the sub-configuration information includes the first parameter, the first parameter includes the first measurement type indication information, and the first measurement type indication information is used to indicate the cell-level measurement method, the mobility measurement result includes at least one first measurement result; in a case where the sub-configuration information includes the first parameter, the first parameter includes the first measurement type indication information, and the first measurement type indication information is used to indicate the beam-level measurement method, the mobility measurement result includes at least one second measurement result.

[0288] In some embodiments of the present application, the measurement result comprises at least one of L3-RSRP, L3-RSRQ, L3-SINR, and L3-RSSI. It can be understood that each first measurement result comprises at least one of L3-RSRP, L3-RSRQ, L3-RSSI, and L3-SINR of one cell associated with the first reference signal, and each second measurement result comprises at least one of L3-RSRP, L3-RSRQ, L3-RSSI, and L3-SINR of at least one beam corresponding to one cell associated with the first reference signal.

[0289] As can be seen, since the embodiments of the present application specify the specific content required by the mobility measurement result, the terminal can report the specific content accordingly, so that the network device can accurately manage the mobility of the terminal according to the specific content, thereby improving the communication quality of the terminal.

[0290] In some embodiments of the present application, after step 102 and before step 103, the mobility measurement method provided by the embodiments of the present application can further comprise the following step 104.

[0291] Step 104, the terminal determines the association relationship between the first reference signal and at least one cell corresponding to the mobility measurement result.

[0292] In some embodiments of the present application, the terminal determines the association relationship between the first reference signal and at least one cell corresponding to the mobility measurement result satisfies at least one of the following:

[0293] According to the indication of the network device;

[0294] The terminal assumes that each TRP sending the first reference signal corresponds to one cell.

[0295] According to a first identifier corresponding to each TRP sending the first reference signal.

[0296] In the embodiments of the present application, the first identifier comprises at least one of a physical cell identifier (PCI), a cell global identifier (CGI), and an absolute radio frequency channel number (ARFCN).

[0297] In some embodiments of the present application, the network device can be a first network device and / or a second network device. Of course, the network device can also be other network devices, which are not limited in the embodiments of the present application.

[0298] In some embodiments of the present application, in a case where the terminal determines that the association relationship of the at least one cell corresponding to the first reference signal and the mobility measurement result meets the condition determined according to the indication of the network device, the network device can indicate which first reference signals transmitted by the TRPs belong to the same cell or directly indicate which first reference signals belong to the same cell, so that the terminal can determine the measurement results corresponding to the first reference signals transmitted by the TRPs belonging to the same cell as one first measurement result to obtain at least one first measurement result; and / or, so that the terminal can determine the measurement results corresponding to one beam of the first reference signals transmitted by the TRPs belonging to the same cell as one second measurement result to obtain at least one second measurement result.

[0299] In some embodiments of the present application, in a case where the terminal determines that the association relationship of the at least one cell corresponding to the first reference signal and the mobility measurement result meets the condition that the terminal assumes that each TRP transmitting the first reference signal corresponds to one cell, the terminal can determine that each TRP transmitting the first reference signal corresponds to a different cell, respectively.

[0300] In some embodiments of the present application, in a case where the terminal determines that the association relationship of the at least one cell corresponding to the first reference signal and the mobility measurement result meets the condition determined according to the first identifier corresponding to each TRP transmitting the first reference signal, the terminal can determine that the TRPs corresponding to the same first identifier belong to the same cell, so that the terminal can determine the measurement results corresponding to the first reference signals transmitted by the TRPs belonging to the same cell as one first measurement result to obtain at least one first measurement result; and / or, so that the terminal can determine the measurement results corresponding to one beam of the first reference signals transmitted by the TRPs belonging to the same cell as one second measurement result to obtain at least one second measurement result.

[0301] One implementation: TRPs with the same physical cell ID (PCI) are regarded as TRPs in one cell, and the first reference signals sent by these TRPs belong to the same cell; or TRPs with the same Cell Global Identifier (CGI) are regarded as TRPs in one cell, and the first reference signals sent by these TRPs belong to the same cell; or TRPs with the same PCI and CGI are regarded as TRPs in one cell, and the first reference signals sent by these TRPs belong to the same cell; or TRPs with the same PCI and frequency point (such as Absolute Radio Frequency Channel Number (ARFCN)) are regarded as TRPs in one cell, and the first reference signals sent by these TRPs belong to the same cell; or TRPs with the same PCI, NCGI, and frequency point are regarded as TRPs in one cell, and the first reference signals sent by these TRPs belong to the same cell.

[0302] Therefore, the terminal can accurately determine the association relationship between the at least one cell corresponding to the first reference signal and the mobility measurement result according to at least one of the following manners: determining according to the indication of the network device, assuming by the terminal that each TRP sending the first reference signal corresponds to one cell, and determining according to the first identifier corresponding to each TRP sending the first reference signal. In this way, the terminal can accurately determine the at least one first measurement result and / or the second measurement result according to the association relationship, and report the required mobility measurement result according to the requirement of the network device. Therefore, the network device can accurately perform mobility management on the terminal according to the required mobility measurement result, thereby improving the communication quality of the terminal.

[0303] The embodiment of the present application provides a mobility measurement method. A terminal can acquire a first mobility measurement request, and perform mobility measurement on a first reference signal according to the first mobility measurement request. The first reference signal is used for at least one of the following: positioning measurement, perception measurement. Since the terminal can perform mobility measurement on the first reference signal used for positioning measurement or perception measurement according to the first mobility measurement request, the positioning measurement resource or the perception measurement resource is multiplexed for mobility measurement, thereby solving the problem of poor measurement accuracy caused by the limitation of SSB configuration on mobility measurement. Meanwhile, the terminal can also perform mobility measurement on the first reference signal according to the first mobility measurement request in the process of performing positioning measurement and / or perception measurement on the first reference signal. In this way, the terminal does not need to additionally perform mobility measurement on SSB, thereby reducing the number of times of measurement of the terminal, and thereby reducing the power consumption of the terminal.

[0304] FIG. 6 shows a flow diagram of a mobility measurement method according to an embodiment of the present application. As shown in FIG. 6, the mobility measurement method according to an embodiment of the present application can include the following step 301.

[0305] Step 301: The first network device sends a first mobility measurement request to the terminal.

[0306] In the embodiments of the present application, the first mobility measurement request is used to request to perform mobility measurement on the first reference signal, and the first reference signal is used for at least one of the following: positioning measurement, perception measurement.

[0307] It should be noted that the description of the first reference signal can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0308] In some embodiments of the present application, when the terminal starts to perform positioning measurement and / or perception measurement, the terminal can send a first notification to the first network device, and the first notification is used to notify the terminal to start to perform positioning measurement and / or perception measurement, so that the first network device can send the first mobility measurement request to the terminal according to the first notification.

[0309] It can be understood that, since the terminal can indicate the first network device through the first notification when the terminal starts to perform positioning measurement and / or perception measurement, the first network device can send the first mobility measurement request to the terminal, and then the terminal can perform mobility measurement on the first reference signal, so that the terminal can perform mobility measurement on the first reference signal at the same time when the terminal performs positioning measurement and / or perception measurement on the first reference signal, without the terminal additionally performing mobility measurement on the SSB, thereby reducing the number of times of measurement of the terminal.

[0310] In some embodiments of the present application, when the terminal starts to perform positioning measurement and / or perception measurement, the second network device can send a third notification to the first network device, and the third notification is used to notify the terminal to start to perform positioning measurement and / or perception measurement, so that the first network device can send the first mobility measurement request to the terminal according to the third notification.

[0311] In some embodiments of the present application, the first reference signal is configured in N time windows, and the N time windows satisfy at least one of the following:

[0312] The length of each time window is less than or equal to a second threshold;

[0313] N is greater than or equal to 1;

[0314] N is less than or equal to a third threshold.

[0315] Therefore, the length of the N time windows is less than or equal to the second threshold, so that the terminal can avoid the situation that the measurement time of the terminal for performing the mobility measurement is too long due to the length of the N time windows being too long, and thus the power consumption of the terminal can be reduced; and the number N of the N time windows can be greater than or equal to 1 and / or less than or equal to the third threshold, so that the terminal can concentrate on performing the mobility measurement multiple times, and thus the accuracy of the mobility measurement result obtained by the measurement can be improved.

[0316] In some embodiments of the present application, as shown in FIG. 7, before step 301, the mobility measurement method provided by the embodiments of the present application can further include the following step 401 in combination with FIG. 6.

[0317] In step 401, the first network device sends first configuration information to the terminal.

[0318] In the embodiments of the present application, the first configuration information is used to configure the use of the first reference signal, and the use includes at least one of the following: positioning measurement, perception measurement.

[0319] In some embodiments of the present application, the first configuration information can include auxiliary information, and the auxiliary information includes a plurality of configuration information of a plurality of reference signals of a plurality of cells and / or a plurality of transmission / reception points (TRPs), each configuration information being used to configure the use of a reference signal associated with one cell and / or one TRP.

[0320] In the embodiments of the present application, the plurality of configuration information can be grouped according to TRPs and / or grouped according to frequency layers.

[0321] In the case of grouping the plurality of configuration information according to TRPs, the first configuration information can include a TRP list, the TRP list including at least one TRP, and each TRP including configuration information corresponding to the TRP. In each TRP, the identity (such as at least one of a TRP ID, a PCI, and a CGI) of the corresponding TRP can be included.

[0322] In the case of grouping the plurality of configuration information according to frequency layers, the first configuration information can include a frequency layer list, the frequency layer list including at least one frequency layer, each frequency layer including a TRP list, each TRP list including a plurality of TRPs, and each TRP including configuration information corresponding to the TRP. In each TRP, the identity (such as at least one of a TRP ID, a PCI, and a CGI) of the corresponding TRP can be included.

[0323] The multiple configuration information can further include configuration information of a resource set list of the reference signal and a resource set level of the reference signal, for example, including an identifier of the resource set, a bandwidth of the resource set, a starting position of the resource set, a period of the resource set, a slot offset of the resource set, a repeated transmission resource of the resource set, a muting pattern of the resource set, and the like. Each resource set includes a resource list of the reference signal and configuration information of a resource level of the reference signal, for example, an ID of the resource, a sequence ID of the resource, a comb, a number of symbols, a resource element (RE) offset, quasi-co-located (QCL), and the like.

[0324] The assistance information can be referred to as positioning assistance information or perception assistance information, which is not limited in the embodiments of the present application. Optionally, the assistance information can be PosSystemInformation or NR-DL-PRS-AssistanceData.

[0325] It can be learned that, since the first configuration information can configure the use of the first reference signal as at least one of the positioning measurement and the perception measurement, the terminal can accurately determine the first reference signal according to the first mobility measurement request and the first configuration information after the first network device sends the first configuration information to the terminal, without receiving other configuration information, so that the resources occupied by the first network device due to sending other configuration information can be saved; and the first configuration information configures the use of the first reference signal as a use different from the mobility measurement, so that the first network device sends the first reference signal, and the terminal can perform multiple measurements without sending multiple reference signals, so that the power consumption and the overhead of the first network device can be reduced; thereby, the resources of the first network device can be saved while the power consumption and the overhead of the first network device are reduced.

[0326] In some embodiments of the present application, in the case that the first configuration information does not include the assistance information, the first network device or the second network device can further send the assistance information to the terminal before the step 401.

[0327] In some embodiments of the present application, before the step 301, the mobility measurement method provided by the embodiments of the present application can further include the following step 402.

[0328] In the step 402, the first network device sends second configuration information to the terminal.

[0329] In the embodiments of the present application, the second configuration information is used to determine the first reference signal.

[0330] In some embodiments of the present application, the first reference signal indicated by the first mobility measurement request or the second configuration information is a subset or the whole set of the first reference signal indicated by the first configuration information; wherein the first configuration information is used for configuring the use of the first reference signal, and the use includes at least one of the following: positioning measurement, sensing measurement; and the second configuration information is used for determining the first reference signal.

[0331] It should be noted that, in the embodiments of the present application, the A configuration is a subset or the whole set of the B configuration, which can be understood as: the A configuration is part of the B configuration or the whole B configuration; or the first reference signal indicated by the A configuration is a subset or the whole set of the first reference signal indicated by the B configuration; or the first reference signal indicated by the A configuration is not more than the range of the first reference signal indicated by the B configuration.

[0332] As can be seen, since the first reference signal indicated by the first mobility measurement request or the second configuration information can be a subset or the whole set of the first reference signal indicated by the first configuration information, after the first network device sends the first configuration information, the terminal can determine the first reference signal without sending other configuration information, thereby saving the resources occupied by sending other configuration information.

[0333] As can be seen, since the second configuration information is used for determining the first reference signal, after the first network device sends the second configuration information to the terminal, the terminal can accurately determine the first reference signal and accurately perform mobility measurement on the first reference signal according to the first mobility measurement request, thereby enabling the terminal to obtain accurate mobility measurement results.

[0334] In a possible implementation manner of the present application, the first mobility measurement request includes at least one of the following:

[0335] An identifier of at least one frequency layer associated with the first reference signal;

[0336] An identifier of at least one cell associated with the first reference signal;

[0337] An identifier of at least one TRP associated with the first reference signal;

[0338] An identifier of at least one resource set associated with the first reference signal;

[0339] An identifier of at least one resource associated with the first reference signal;

[0340] The second configuration information;

[0341] A response time requirement;

[0342] A mobility request identifier.

[0343] It should be noted that the description of the identification of the at least one frequency layer associated with the first reference signal, the identification of the at least one cell associated with the first reference signal, the identification of the at least one TRP associated with the first reference signal, the identification of the at least one resource set associated with the first reference signal, and the identification of the at least one resource associated with the first reference signal can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0344] In the embodiments of the present application, the second configuration information is used to determine the first reference signal.

[0345] In some examples, the second configuration information is used to determine the first reference signal for which the mobility measurement is performed.

[0346] In the embodiments of the present application, the response time requirement is used to indicate the latest time for the terminal to feed back the mobility measurement result, which is the measurement result of the mobility measurement on the first reference signal.

[0347] In the embodiments of the present application, the mobility request identification is used to indicate that the terminal performs the mobility measurement on the first reference signal.

[0348] As can be seen, since the embodiments of the present application specify the specific content required to be included in the first mobility measurement request, the terminal can accurately measure the first reference signal according to the specific content after the first network device sends the first mobility measurement request to the terminal.

[0349] In some embodiments of the present application, the second configuration information includes at least one sub-configuration information, and each sub-configuration information is used to configure the terminal to perform the mobility measurement on a target object associated with the first reference signal; wherein each target object includes at least one of the following: at least one measurement target, at least one frequency layer.

[0350] In some embodiments of the present application, each sub-configuration information can include one measurement target or one frequency layer.

[0351] In some embodiments of the present application, in the case where each target object includes at least one measurement target, the identification of each frequency layer corresponding to each measurement target is further included in the second configuration information.

[0352] As can be seen, since each sub-configuration information included in the second configuration information is used to configure the terminal to perform the mobility measurement on a target object associated with the first reference signal, the terminal can perform the mobility measurement on each target object according to each sub-configuration information, so as to accurately perform the mobility measurement on the first reference signal.

[0353] In some embodiments of the present application, in the case that each target object includes at least one frequency layer, or each target object includes at least one measurement target and each measurement target corresponds to at least one frequency layer, the second configuration information further includes at least one of the following:

[0354] a first bitmap, used to indicate the at least one frequency layer;

[0355] an identifier of the at least one frequency layer.

[0356] It should be noted that the description of the first bitmap and the identifier of the at least one frequency layer can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0357] As can be seen, since the first bitmap and / or the identifier of the at least one frequency layer can be included in the second configuration information, the terminal can accurately obtain the at least one frequency layer on which the mobility measurement needs to be performed from the second configuration information, and thus the terminal can accurately perform the mobility measurement on the at least one frequency layer.

[0358] In some embodiments of the present application, each sub-configuration information includes at least one of the following:

[0359] cell indication information, used to indicate at least one cell on which the mobility measurement needs to be performed;

[0360] TRP indication information, used to indicate at least one TRP on which the mobility measurement needs to be performed;

[0361] resource set indication information, used to indicate at least one resource set on which the mobility measurement needs to be performed;

[0362] resource indication information, used to indicate at least one resource on which the mobility measurement needs to be performed;

[0363] time domain resource indication information, used to indicate at least part of the time domain resources in the at least one resource on which the mobility measurement needs to be performed;

[0364] repeated transmission resource indication information, used to indicate at least part of the repeated transmission resources in the at least one resource on which the mobility measurement needs to be performed;

[0365] measurement indication information, used to indicate that the terminal performs the mobility measurement on the first reference signal within a mobility measurement window;

[0366] frequency domain range indication information, used to indicate a frequency domain range on which the mobility measurement needs to be performed;

[0367] a first parameter related to the mobility measurement.

[0368] In some embodiments of the present application, the above cell indication information includes at least one of the following:

[0369] an identity of the at least one cell;

[0370] indication information of a TRP associated with each cell in the at least one cell.

[0371] It should be noted that the description of the identity of the at least one cell can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0372] In some embodiments of the present application, the TRP indication information includes at least one of the following:

[0373] a second bitmap, used to indicate a TRP associated with each cell in the at least one cell;

[0374] an identity of the TRP associated with each cell in the at least one cell.

[0375] It should be noted that the description of the second bitmap and the identity of the TRP can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0376] As can be seen, since the embodiments of the present application specify the specific content of the TRP indication information, the terminal can accurately determine each TRP to be measured according to the specific content, and therefore the terminal can accurately measure the first reference signal sent by each TRP.

[0377] As can be seen, since the embodiments of the present application specify the specific content included in the cell indication information, the terminal can accurately determine the at least one cell to be measured and / or at least one first TRP in the at least one cell to send the first reference signal according to the specific content, and therefore the terminal can accurately measure the first reference signal of the at least one cell and / or the first reference signal sent by the at least one TRP associated with the at least one cell.

[0378] In some embodiments of the present application, the resource set indication information includes at least one of the following:

[0379] a third bitmap, used to indicate at least one resource set;

[0380] an identity of the at least one resource set.

[0381] It should be noted that the description of the third bitmap and the identity of the at least one resource set can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0382] Therefore, the terminal can accurately determine the at least one resource to be measured according to the specific content included in the resource indication information, and thus can accurately measure the at least one resource.

[0383] In some embodiments of the present application, the resource indication information includes at least one of the following:

[0384] a fourth bitmap, used to indicate the at least one resource;

[0385] an identifier of the at least one resource.

[0386] It should be noted that the description of the fourth bitmap and the identifier of the at least one resource can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0387] Therefore, the terminal can accurately determine the at least one resource to be measured according to the specific content included in the resource indication information, and thus can accurately measure the at least one resource.

[0388] In some embodiments of the present application, the at least part of the time domain resource can include at least one of the following: symbol, time slot, subframe, etc.

[0389] In some embodiments of the present application, the time domain resource indication information includes at least one of the following:

[0390] a fifth bitmap, used to indicate the at least part of the time domain resource;

[0391] an index of the at least part of the time domain resource.

[0392] It should be noted that the description of the fifth bitmap can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0393] Therefore, the terminal can accurately determine the at least part of the time domain resource to be measured according to the specific content included in the time domain resource indication information, and thus can accurately measure the at least part of the time domain resource.

[0394] In some embodiments of the present application, the repeated transmission can include at least one of the following: intra-slot repetition, inter-slot repetition, all of intra-slot and inter-slot repetition.

[0395] It can be understood that in an example, the terminal can only measure part of the repeated transmission resources in the at least one resource, and thus can obtain the mobility measurement result.

[0396] In some embodiments of the present application, the number of at least partially repeated transmission resources is at least one, and each resource includes one repeated transmission resource.

[0397] It can be understood that for one resource for which mobility measurement is performed, the terminal only needs to measure one repeated transmission resource to obtain the mobility measurement result.

[0398] In embodiments of the present application, each target object corresponds to one measurement indication information, and it can be understood that each target object is configured with one mobility measurement window.

[0399] In some embodiments of the present application, the mobility measurement window can reuse the SSB measurement time configuration (SSB Measurement Time Configuration, SMTC), for example, the SMTC is used as the mobility measurement window, and the mobility measurement is performed in the SMTC.

[0400] In some embodiments of the present application, the mobility measurement window can be referred to as a positioning reference signal measurement time configuration (PRS Measurement Time Configuration, PMTC). Of course, the mobility measurement window can also be referred to as other names, which are not limited in embodiments of the present application.

[0401] In some embodiments of the present application, the terminal does not expect to perform mobility measurement on the first reference signal outside the mobility measurement window.

[0402] In some embodiments of the present application, the timing of the mobility measurement window can be a serving cell of the terminal. For example, the serving cell can be the primary cell Pcell by default, or the serving cell that sends the second configuration information or the first mobility measurement request, or the serving cell indicated by the network device.

[0403] In some embodiments of the present application, the measurement indication information can include at least one of the following:

[0404] An identifier of the mobility measurement window;

[0405] A period of the mobility measurement window;

[0406] A duration of the mobility measurement window;

[0407] A starting time or offset of the mobility measurement window.

[0408] The starting time or offset includes at least one of the following: system frame number (System Frame Number, SFN), slot offset, symbol offset.

[0409] In some embodiments of the present application, the mobility measurement window described above can be configured simultaneously with a measurement gap or a reference signal processing window (e.g., a positioning reference signal processing window (PPW)) configured for positioning measurement and / or perception measurement.

[0410] In an example, if a measurement gap or a reference signal processing window is configured for mobility measurement, the terminal does not expect the mobility measurement window described above to exceed the measurement gap or the reference signal processing window.

[0411] In some embodiments of the present application, the frequency domain range described above can be smaller than the frequency domain range of the first reference signal actually transmitted; or, smaller than the frequency domain range of the first reference signal configured in positioning or perception.

[0412] In some embodiments of the present application, the frequency domain range indication information includes at least one of the following:

[0413] Frequency domain position indication information, used to indicate a first starting frequency domain position of the frequency domain range for mobility measurement;

[0414] Bandwidth indication information, used to indicate a first bandwidth of the frequency domain range for mobility measurement.

[0415] As can be seen, since the specific content included in the frequency domain range indication information is specified in the embodiments of the present application, the terminal can accurately determine the frequency domain range for mobility measurement according to the specific content, and thus the terminal can accurately perform mobility measurement on the frequency domain range.

[0416] In some embodiments of the present application, the first parameter includes at least one of the following:

[0417] First measurement quantity indication information, used to indicate a measurement quantity required to be measured;

[0418] A first threshold, which is a threshold used to filter out a mobility measurement result from measurement results obtained by performing mobility measurement, the mobility measurement result being a measurement result of mobility measurement on the first reference signal;

[0419] A first number, which is a maximum number of measurement results allowed to be processed simultaneously;

[0420] A first filter coefficient, which is a filter coefficient used for mobility measurement;

[0421] First measurement type indication information, used to indicate a measurement manner for mobility measurement.

[0422] It should be noted that the description of the first measurement quantity indication information, the first threshold, the first quantity, the first filtering system, and the first measurement type indication information can refer to the specific description in the above embodiments, and the present application embodiment will not repeat it here.

[0423] Therefore, it can be known that, since the specific content included in the first parameter is specified in the embodiments of the present application, the terminal can accurately measure the first reference signal according to the specific content.

[0424] In some embodiments of the present application, before the above step 301, the mobility measurement method provided by the embodiments of the present application can further include the following steps 403 to 405.

[0425] Step 403, the first network device sends a first configuration request to the second network device.

[0426] In some embodiments of the present application, the first configuration request can be carried by a first message, which can be an NRPPa message, or a UE-associated message, or a cell-associated message, or a multiple UE associated message. Of course, the first message can also be other messages, which are not limited by the embodiments of the present application.

[0427] In the embodiments of the present application, the first configuration request is used to request third configuration information, and the third configuration information is used to configure the purpose of the first reference signal, which includes at least one of the following: positioning measurement, perception measurement.

[0428] The configuration information included in the third configuration information can be the same as the information included in the first configuration information.

[0429] Step 404, the first network device receives the third configuration information from the second network device.

[0430] Optionally, the first network device receiving the third configuration information from the second network device can determine which configuration information in the third configuration information can be used for mobility measurement, or which configuration information in the third configuration information corresponds to the first reference signal that can be used for mobility measurement.

[0431] Step 405, the first network device determines at least one of the following according to the third configuration information: the first mobility measurement request, the first configuration information, and the second configuration information.

[0432] In the embodiments of the present application, the first configuration information is used to configure the purpose of the first reference signal, which includes at least one of the following: positioning measurement, perception measurement; and the second configuration information is used to determine the first reference signal.

[0433] Therefore, the terminal can accurately perform the mobility measurement, the positioning measurement, and / or the perception measurement on the first reference signal according to the first mobility measurement request and / or the first configuration information and / or the second configuration information.

[0434] Alternatively, the terminal receives the first configuration information from the first network device or the second network device in the process of positioning or perception. The first configuration information itself is used for the positioning or perception measurement. Optionally, the first configuration information includes the positioning or perception assistance information, which can be broadcasted, multicast, or unicast.

[0435] In some embodiments of the present application, in the case that the terminal stops the positioning measurement and / or the perception measurement, the terminal can send a second notification to the first network device, the second notification being used for notifying the terminal to stop the positioning measurement and / or the perception measurement, so that the first network device can send a second mobility measurement request to the terminal, the second mobility measurement request being used for requesting the terminal to stop the mobility measurement on the first reference signal.

[0436] It can be understood that, in the case that the terminal stops the positioning measurement and / or the perception measurement, the terminal can indicate the first network device or the second network device through the second notification, so that the first network device or the second network device can send the second mobility measurement request to the terminal, and then the terminal can stop the mobility measurement on the first reference signal. Therefore, the terminal can stop the mobility measurement on the first reference signal while stopping the positioning measurement and / or the perception measurement on the first reference signal, so as to avoid the terminal performing additional measurement on the first reference signal, and thus the number of measurements performed by the terminal can be reduced.

[0437] In some embodiments of the present application, in the case that the terminal stops the positioning measurement and / or the perception measurement, the second network device can send a fourth notification to the first network device, the fourth notification being used for notifying the terminal to stop the positioning measurement and / or the perception measurement, so that the first network device can send a second mobility measurement request to the terminal, the second mobility measurement request being used for requesting the terminal to stop the mobility measurement on the first reference signal.

[0438] In some embodiments of the present application, after the step 301, the mobility measurement method provided by the embodiments of the present application can further include the following step 302.

[0439] In step 302, the first network device receives the mobility measurement result from the terminal.

[0440] In the embodiments of the present application, the mobility measurement result is a measurement result of mobility measurement on the first reference signal.

[0441] Therefore, the first network device can accurately perform mobility management on the terminal according to the mobility measurement result, and the accuracy of mobility management of the first network device can be improved.

[0442] In some embodiments of the present application, the mobility measurement result includes at least one of the following:

[0443] at least one first measurement result, each first measurement result being a measurement result of a cell associated with the first reference signal;

[0444] at least one second measurement result, each second measurement result being a measurement result of at least one beam corresponding to a cell associated with the first reference signal.

[0445] Therefore, the first network device can accurately perform mobility management on the terminal according to the specific content of the mobility measurement result, and the accuracy of mobility management of the first network device can be improved.

[0446] The embodiments of the present application provide a mobility measurement method. The first network device can send a first mobility measurement request for requesting mobility measurement on a first reference signal to a terminal. The first reference signal is used for at least one of the following: positioning measurement, perception measurement. Since the first network device can instruct the terminal to multiplex the first reference signal for positioning measurement or perception measurement for mobility measurement through the first mobility measurement request, the terminal is no longer limited by SSB configuration when performing mobility measurement, and the measurement accuracy can be improved. Further, the terminal can also perform mobility measurement on the first reference signal during positioning measurement and / or perception measurement on the first reference signal, so that the terminal does not need to additionally perform mobility measurement on SSB, and the number of measurements of the terminal can be reduced. Furthermore, since the terminal performs mobility measurement on the first reference signal, the mobility measurement result can be obtained, so that the first network device does not need to additionally send SSB for the terminal to perform mobility measurement, and the power consumption and overhead of the first network device can be reduced. Therefore, the power consumption of the terminal can be reduced while reducing the power consumption and overhead of the first network device.

[0447] The mobility measurement method provided by the embodiments of the present application will be described below with specific examples.

[0448] Example 1, assuming the first reference signal is PRS, the first network device is a serving gNB, the second network device is an LMF network element, and the terminal is a UE, as shown in FIG. 8, the mobility measurement method provided by the embodiment of the application includes the following steps:

[0449] Step 0: The UE obtains PRS assistance information (such as the above-mentioned assistance information or the first configuration information in the above-mentioned embodiment) sent by the LMF network element in the positioning process, which contains multiple configuration information of multiple cells and / or multiple TRPs. It should be noted that this step 0 is an optional step, and this step 0 can not be performed.

[0450] Step 1: The serving gNB sends a request (such as the first configuration request in the above-mentioned embodiment) to the LMF network element to request PRS configuration information (the third configuration information in the above-mentioned embodiment).

[0451] Step 2: The LMF network element sends the PRS configuration information (such as the third configuration information in the above-mentioned embodiment) to the serving gNB.

[0452] Step 3: The serving gNB determines the PRS configuration information (such as the second configuration information) for mobility measurement according to the PRS configuration information to determine a specific PRS (such as the first reference signal).

[0453] Step 4: The serving gNB requests or instructs the UE to perform mobility measurement on the specific PRS (such as the first reference signal) (for example, the serving gNB sends a first mobility measurement request to the UE).

[0454] Optionally, the first mobility measurement request in step 4 can contain the second configuration information.

[0455] Optionally, considering that the UE has obtained complete PRS configuration information in step 0, the instruction in step 4 can only be an instruction of a cell, a TRP, a PRS resource set, or a PRS resource index or identifier. Optionally, if the UE does not obtain complete PRS configuration (such as the UE does not in the positioning process), the PRS request / instruction in step 4 can contain complete PRS configuration information.

[0456] Optionally, the first mobility measurement request in step 4 can not contain the second configuration information; then, optionally, the serving gNB can instruct the UE of the second configuration information before or after step 4.

[0457] Step 5: According to the content of step 4, the UE performs mobility measurement (such as RRM measurement) on the specific PRS (such as the first reference signal) to obtain cell-level or PRS beam-level mobility measurement results (such as at least one first measurement result or at least one second measurement result in the above-mentioned embodiment).

[0458] Step 6: The UE reports the mobility measurement result obtained in step 5 to the serving gNB.

[0459] Optionally, as shown in FIG. 9, from the perspective of UE power saving, the RRM measurement of PRS by the UE is not a dedicated step, but a (incidental) measurement performed at the same time when the UE performs positioning measurement. Therefore, before the UE starts the positioning measurement (or before the UE receives the positioning measurement request), the UE is not expected to measure the PRS for RRM.

[0460] Therefore, before step 4, the LMF network element sends a PRS measurement start notification (for example, the third notification described above) to the serving gNB, notifying that the UE is about to start measuring the PRS. According to this message, the serving gNB instructs the UE to perform RRM measurement on the PRS (for example, sends the first mobility measurement request to the UE). Optionally, the serving gNB sends a corresponding feedback confirmation to this signaling after receiving the 'PRS start notification'. Optionally, the PRS measurement start notification can also be sent by the UE to the serving gNB (for example, the UE can send the first notification to the serving gNB).

[0461] Further, with the end of the PRS measurement, the LMF network element can further send a PRS measurement completion notification (for example, the fourth notification in the above embodiment) to the serving gNB, notifying that the UE is about to end the measurement (positioning related measurement) on the PRS. According to this message, the serving gNB instructs the UE to perform RRM measurement on the PRS. Optionally, the serving gNB sends a corresponding feedback confirmation to this signaling after receiving the 'PRS start notification'. Optionally, the 'PRS measurement completion notification' can also be sent by the UE to the serving gNB (for example, the UE can send the second notification to the serving gNB). Optionally, the serving gNB subsequently sends a'request / instruction for the UE to stop / end RRM measurement on the PRS' message to the UE.

[0462] FIG. 10 shows a flow diagram of a mobility measurement method according to an embodiment of the present application. As shown in FIG. 10, the mobility measurement method according to an embodiment of the present application can include the following step 501.

[0463] Step 501: The second network device sends a first mobility measurement request to the terminal.

[0464] In the embodiment of the present application, the first mobility measurement request is used to request mobility measurement on a first reference signal, and the first reference signal is used for at least one of the following: positioning measurement, perception measurement.

[0465] It should be noted that the description of the first reference signal can refer to the specific description in the above embodiments, which is not limited in the embodiments of the present application.

[0466] In some embodiments of the present application, before step 501, the mobility measurement method provided by the embodiments of the present application can further include steps 601-603.

[0467] Step 601: The second network device receives a first measurement result request from the first network device.

[0468] In the embodiments of the present application, the first measurement result request is used to request the terminal to perform mobility measurement on the first reference signal.

[0469] In some embodiments of the present application, the first measurement result request includes at least one of the following:

[0481] In the embodiments of the present application, the measurement manner includes at least one of the following: a cell-level measurement manner, and a beam-level measurement manner, the cell-level measurement manner being a manner of performing mobility measurement on the first reference signal according to a cell granularity, and the beam-level measurement being a manner of performing mobility measurement on the first reference signal according to a beam granularity.

[0482] Step 602: The second network device determines second configuration information according to the first measurement result request.

[0483] In the embodiments of the present application, the second configuration information is used to determine the first reference signal.

[0484] In step 603, the second network device sends the second configuration information to the terminal.

[0485] Therefore, the terminal can accurately determine the first reference signal and perform mobility measurement on the first reference signal according to the second configuration information in the case of receiving the first mobility measurement request, because the second network device can determine the second configuration information according to the first measurement result request of the first network device and send the obtained second configuration information to the terminal.

[0486] In some embodiments of the present application, the second configuration information includes at least one sub-configuration information, and each sub-configuration information is used to configure the terminal to perform mobility measurement on a target object associated with the first reference signal; wherein each target object includes at least one of the following: at least one measurement target, at least one frequency layer.

[0487] In some embodiments of the present application, each sub-configuration information can include one measurement target or one frequency layer.

[0488] In some embodiments of the present application, in the case that each target object includes at least one measurement target, the second configuration information further includes an identifier of each frequency layer corresponding to each measurement target.

[0489] Therefore, the terminal can perform mobility measurement on each target object according to each sub-configuration information to accurately perform mobility measurement on the first reference signal, because each sub-configuration information included in the second configuration information is used to configure the terminal to perform mobility measurement on a target object associated with the first reference signal.

[0490] In some embodiments of the present application, in the case that each target object includes at least one frequency layer, or each target object includes at least one measurement target and each measurement target corresponds to at least one frequency layer, the second configuration information further includes at least one of the following:

[0491] a first bitmap, used to indicate the at least one frequency layer;

[0492] an identifier of the at least one frequency layer.

[0493] It should be noted that the description of the first bitmap and the identifier of the at least one frequency layer can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0494] Therefore, the terminal can accurately acquire at least one frequency layer on which mobility measurement needs to be performed from the second configuration information, and thus can accurately perform mobility measurement on the at least one frequency layer.

[0495] In some embodiments of the present application, each sub-configuration information comprises at least one of the following:

[0496] cell indication information for indicating at least one cell on which mobility measurement needs to be performed;

[0509] In some embodiments of the present application, the above-mentioned TRP indication information comprises at least one of the following:

[0510] a second bitmap for indicating a TRP associated with each cell in the at least one cell;

[0511] an identity of a TRP associated with each of the at least one cell.

[0512] It should be noted that the description of the second bitmap and the identity of the TRP can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated.

[0513] As can be seen, since the embodiments of the present application specify the specific content of the TRP indication information, the terminal can accurately determine each TRP to be measured according to the specific content, and therefore the terminal can accurately measure the first reference signal transmitted by each TRP.

[0514] As can be seen, since the embodiments of the present application specify the specific content included in the cell indication information, the terminal can accurately determine the at least one cell to be measured and / or at least one first TRP in the at least one cell to transmit the first reference signal according to the specific content, and therefore the terminal can accurately measure the first reference signal of the at least one cell and / or the first reference signal transmitted by at least one TRP associated with the at least one cell.

[0515] In some embodiments of the present application, the above-mentioned resource set indication information includes at least one of the following:

[0516] a third bitmap, used to indicate at least one resource set;

[0517] an identity of the at least one resource set.

[0518] It should be noted that the description of the third bitmap and the identity of the at least one resource set can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated.

[0519] As can be seen, since the embodiments of the present application specify the specific content included in the resource set indication information, the terminal can accurately determine the at least one resource set to be measured according to the specific content, and therefore the terminal can accurately measure the at least one resource set.

[0520] In some embodiments of the present application, the above-mentioned resource indication information includes at least one of the following:

[0521] a fourth bitmap, used to indicate at least one resource;

[0522] an identity of the at least one resource.

[0523] It should be noted that the description of the fourth bitmap and the identity of the at least one resource can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated.

[0524] Therefore, the terminal can accurately determine the at least one resource to be measured according to the specific content included in the resource indication information, and thus can accurately measure the at least one resource.

[0525] In some embodiments of the present application, the at least part of time domain resources can include at least one of the following: a symbol, a time slot, a subframe, etc.

[0526] In some embodiments of the present application, the time domain resource indication information includes at least one of the following:

[0527] The fifth bit pattern is used to indicate at least part of time domain resources.

[0528] The index of the at least part of time domain resources.

[0529] It should be noted that the description of the fifth bit pattern can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0530] Therefore, the terminal can accurately determine the at least part of time domain resources to be measured according to the specific content included in the time domain resource indication information, and thus can accurately measure the at least part of time domain resources.

[0531] In some embodiments of the present application, the repeated transmission can include at least one of the following: intra-slot repetition, inter-slot repetition, and all of intra-slot and inter-slot repetition.

[0532] It can be understood that in an example, the terminal can only measure part of the repeated transmission resources in the at least one resource, and thus can obtain the mobility measurement result.

[0533] In some embodiments of the present application, the number of the at least part of repeated transmission resources is at least one, and each resource includes one repeated transmission resource.

[0534] It can be understood that for one resource for which mobility measurement is performed, the terminal only needs to measure one repeated transmission resource to obtain the mobility measurement result.

[0535] In the embodiments of the present application, each target object corresponds to one measurement indication information, and it can be understood that each target object is respectively configured with one mobility measurement window.

[0536] In some embodiments of the present application, the mobility measurement window can reuse the SSB measurement time configuration (SSB Measurement Time Configuration, SMTC), that is, the SMTC is used as the mobility measurement window, and the mobility measurement is performed in the SMTC.

[0537] In some embodiments of the present application, the mobility measurement window can be referred to as a positioning reference signal measurement time configuration (PRS Measurement Time Configuration, PMTC). Of course, the mobility measurement window can also be referred to as other names, which are not limited in the embodiments of the present application.

[0538] In some embodiments of the present application, the terminal does not expect to perform mobility measurement on the first reference signal outside the mobility measurement window.

[0539] In some embodiments of the present application, the reference cell of the timing of the mobility measurement window can be the serving cell of the terminal. For example, the serving cell can be the primary cell Pcell by default, or the serving cell that sends the second configuration information or the first mobility measurement request, or the serving cell indicated by the network device.

[0540] In some embodiments of the present application, the measurement indication information can include at least one of the following:

[0541] An identifier of the mobility measurement window;

[0542] A period of the mobility measurement window;

[0545] The starting time or offset includes at least one of the following: system frame number (System Frame Number, SFN), time slot offset, symbol offset.

[0546] In some embodiments of the present application, the mobility measurement window can be configured simultaneously with a measurement gap or a reference signal processing window (such as a positioning reference signal processing window (PRS Processing Window, PPW)) configured for positioning measurement and / or perception measurement.

[0547] In an example, if a measurement gap or a reference signal processing window is configured for mobility measurement, the terminal does not expect the mobility measurement window to exceed the measurement gap or the reference signal processing window.

[0548] In some embodiments of the present application, the frequency domain range indicated by the frequency domain range indication information can be smaller than the frequency domain range of the first reference signal actually transmitted; or, smaller than the frequency domain range of the first reference signal configured in positioning or sensing.

[0549] In some embodiments of the present application, the frequency domain range indication information includes at least one of the following:

[0550] frequency domain position indication information, used for indicating a first starting frequency domain position of the frequency domain range in which the mobility measurement is performed;

[0551] bandwidth indication information, used for indicating a first bandwidth of the frequency domain range in which the mobility measurement is performed.

[0552] As can be seen, since the specific content included in the frequency domain range indication information is specified in the embodiments of the present application, the terminal can accurately determine the frequency domain range in which the mobility measurement is performed according to the specific content, and thus the terminal can accurately perform the mobility measurement on the frequency domain range.

[0553] In some embodiments of the present application, the first parameter includes at least one of the following:

[0554] first measurement quantity indication information, used for indicating a measurement quantity required to be measured;

[0557] a first filter coefficient, which is a filter coefficient used for performing the mobility measurement;

[0558] first measurement type indication information, used for indicating a measurement manner in which the mobility measurement is performed.

[0559] It should be noted that the description of the first measurement quantity indication information, the first threshold, the first number, the first filter system and the first measurement type indication information can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0560] As can be seen, since the specific content included in the first parameter is specified in the embodiments of the present application, the terminal can accurately measure the first reference signal according to the specific content.

[0561] In some embodiments of the present application, after the step 501, the mobility measurement method provided by the embodiments of the present application can further include the following steps 502 and 503.

[0562] In step 502, the second network device receives the mobility measurement result from the terminal.

[0563] In step 503, the second network device sends the mobility measurement result to the first network device.

[0564] Therefore, the second network device can receive the mobility measurement result reported by the terminal, and send the mobility measurement result to the first network device, so that the first network device can accurately perform mobility management on the terminal according to the mobility measurement result, thereby improving the accuracy of mobility management performed by the first network device.

[0565] In some embodiments of the present application, the mobility measurement result includes at least one of the following:

[0566] at least one first measurement result, each first measurement result being a measurement result of a cell associated with the first reference signal;

[0567] at least one second measurement result, each second measurement result being a measurement result of at least one beam corresponding to a cell associated with the first reference signal.

[0568] Therefore, the present application specifies the specific content required by the mobility measurement result, so that the terminal can report the specific content according to the specific content, and the first network device can accurately perform mobility management on the terminal according to the specific content, thereby improving the accuracy of mobility management performed by the first network device.

[0569] The embodiments of the present application provide a mobility measurement method, and the second network device can send a first mobility measurement request for requesting to perform mobility measurement on a first reference signal to the terminal, the first reference signal being used for at least one of the following: positioning the terminal, and sensing a sensing target. Since the second network device can instruct the terminal to perform mobility measurement on the first reference signal through the first mobility measurement request, the terminal can perform mobility measurement on the first reference signal used for positioning measurement or sensing measurement, so that the positioning measurement resource or the sensing measurement resource is multiplexed for mobility measurement, thereby solving the problem of poor measurement accuracy caused by the limitation of SSB configuration on mobility measurement. Meanwhile, the terminal can also perform mobility measurement on the first reference signal according to the first mobility measurement request in the process of performing positioning measurement and / or sensing measurement on the first reference signal, so that the terminal does not need to additionally perform mobility measurement on SSB, thereby reducing the number of measurements performed by the terminal, and thus reducing the power consumption of the terminal.

[0570] The mobility measurement method provided by the embodiments of the present application will be illustrated below by taking specific examples.

[0571] Example two, assuming that the first reference signal is PRS, the first network device is a serving gNB, the second network device is an LMF network element, and the terminal is a UE, as shown in FIG. 11, the mobility measurement method provided by the embodiments of the present application includes the following steps:

[0572] Step 0: The UE obtains PRS assistance information (for example, the above-mentioned assistance information) sent by the LMF network element in the process of positioning, containing multiple configuration information of multiple cells and / or multiple TRPs. It should be noted that this step 0 is an optional step, and this step 0 can not be performed.

[0573] Step 1a: The serving gNB sends a request (for example, the above-mentioned first measurement result request) to the LMF network element, requesting the PRS mobility measurement result of the UE.

[0574] Optionally, the message is carried in an NRPPa message.

[0575] Optionally, the message is a UE-associated message; or the message is a cell-associated message; or the message is a multiple UE associated message.

[0576] Step 3: The LMF network element sends a PRS measurement request (for example, a first mobility measurement request) to the UE.

[0577] Step 4: The UE performs PRS measurement to obtain a mobility measurement result.

[0578] Optionally, the UE simultaneously performs positioning measurement and mobility measurement of PRS

[0579] Step 5: The UE reports the obtained mobility measurement result.

[0580] Optionally, the UE simultaneously reports the positioning measurement result and the mobility measurement result

[0581] Step 6a: The LMF network element feeds back the obtained mobility measurement result to the serving gNB.

[0582] FIG. 12 shows a flow diagram of a mobility measurement result acquisition method provided by the embodiments of the present application. As shown in FIG. 12, the mobility measurement result acquisition method provided by the embodiments of the present application can include the following steps 701 and 702.

[0583] Step 701: The first network device sends a measurement result request to the second network device.

[0584] In the embodiments of the present application, the measurement result request is used to request a terminal to provide a mobility measurement result obtained by performing mobility measurement on a first reference signal, and the first reference signal is used for at least one of the following: positioning the terminal, and sensing a sensing target.
