       FIG.  1    is a block diagram of a wireless communication system to which the embodiments of this application are applicable.

The base station is not limited to a specific technical term. It should be noted that, a base station in the NR system is used as an example in the embodiments of this application, but a specific type of the base station is not limited. 
     A positioning processing method provided in the embodiments of this application is described below through specific embodiments and application scenarios thereof with reference to the accompanying drawings. 
     A user device (UE) in the embodiments of this application may refer to an access terminal, a user unit, a user station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The terminal may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having a wireless communication function, a computing device, another processing device connected to a wireless modem, an in-vehicle device, or a wearable device. 
     As shown in  FIG.  2   , a positioning processing method in this embodiment of this application is applied to a terminal, and includes the following steps. 
     Step  201 . Transmit first signaling to a target cell, where 
     the first signaling is used for activating or deactivating transmission of a positioning-related signal by the target cell of the terminal; and the target cell includes a serving cell and/or a neighboring cell of the terminal. 
     In this way, according to step  201 , the terminal can transmit the first signaling to the target cell, namely, the serving cell and/or the neighboring cell of the terminal, to directly activate or deactivate the transmission of the positioning-related signal by the target cell, so as to reduce delays of positioning, thereby meeting the timeliness requirement for obtaining a positioning reference signal. 
     Therefore, for a scenario with a positioning requirement, the terminal to which the method in this embodiment of this application is applied transmits the first signaling to the serving cell and/or the neighboring cell of the terminal, so that the transmission of the positioning-related signal by the serving cell and/or the neighboring cell can be activated, thereby obtaining the positioning reference signal in time; and for a scenario without the positioning requirement, the first signaling is transmitted to the serving cell and/or the neighboring cell of the terminal, so that the transmission of the positioning-related signal by the serving cell and/or the neighboring cell can be deactivated, thereby avoiding consumption of signaling resources. 
     It should be known that, the target cell is a cell of a network-side device (such as a base station, a transmission reference point (TRP), a reference point (RP), or a radio head). 
     Optionally, in this embodiment, the positioning-related signal includes at least one of the following: 
     second signaling, where the second signaling is used for activating or deactivating transmission of a positioning reference signal by the neighboring cell, or activating or deactivating receiving of the positioning reference signal by the terminal; or 
     a positioning reference signal. 
     Herein, the second signaling is signaling transmitted by a specific cell (such as a cell for positioning control) for activating or deactivating the transmission of the positioning reference signal by the target cell after receiving the first signaling. Alternatively, the specific cell may transmit the second signaling to the target cell of the terminal. Alternatively, the specific cell may also transmit the second signaling to a location management device such as an LMF, and activate or deactivate the transmission of the positioning reference signal by the target cell by using the location management device. The LMF may further activate or deactivate the transmission of the positioning reference signal by the target cell through signaling, and the signaling may use a design the same as that of the first signaling. 
     Alternatively, the specific cell transmits the second signaling to the terminal, and activates or deactivates the receiving of the positioning reference signal by the terminal. 
     In an example, in a case that the target cell is the serving cell and the neighboring cell or the target cell is the neighboring cell, the first signaling is used for activating or deactivating the transmission of the positioning reference signal by the target cell; and in a case that the target cell is the serving cell, the first signaling is used for activating or deactivating the transmission of the second signaling and the positioning reference signal by the target cell. 
     Optionally, the positioning reference signal includes at least one of the following: 
     an on demand positioning reference signal PRS; 
     an aperiodic positioning reference signal PRS; 
     a periodic positioning reference signal PRS; 
     a cell reference signal CRS; 
     a channel state information reference signal CSI-RS; 
     a synchronization signal block SSB; or 
     a tracking reference signal TRS. 
     Herein, the on demand (on demand) positioning reference signal (PRS) is dynamically or semi-statically configured. In an embodiment, the on demand positioning reference signal PRS may be understood as PRS configuration configured or activated according to a demand of the terminal or a service, where the PRS may be periodic, semi-static, or aperiodic; and a manner of the activation or configuration thereof may also be statically, semi-statically, or dynamically configured. Certainly, the positioning reference signal includes, but is not limited to: the on demand PRS, the aperiodic PRS, the periodic PRS, the cell reference signal (CRS), the channel state information reference signal (CSI-RS), the synchronization signal block (SSB), and the tracking reference signal (TRS). 
     It can be learned from the above that, the positioning-related signal may be the second signaling and/or the positioning reference signal. Therefore, optionally, the positioning-related signal transmitted by the target cell includes at least one of the following: 
     determining a to-be-transmitted positioning-related signal; 
     determining a to-be-transmitted positioning reference signal; or 
     determining to-be-transmitted second signaling. 
     That is, in a case that the first signaling is received, the target cell performs at least one of determining the to-be-transmitted positioning-related signal, determining the to-be-transmitted positioning reference signal, or determining the to-be-transmitted second signaling, and then transmits according to the determined content. 
     Determining the to-be-transmitted positioning-related signal refers to determining whether the target cell currently transmits the second signaling, or transmits the positioning reference signal, or transmits both. Determining the to-be-transmitted positioning reference signal refers to determining which positioning reference signal the target cell transmits, how to transmit, and the like, and may also refer to determining to transmit configuration information of the positioning reference signal. Determining the to-be-transmitted second signaling refers to determining which second signaling the target cell transmits, how to transmit the second signaling, a relationship between the second signaling and the positioning reference signal, and the like, and may also refer to determining to transmit configuration information of the second signaling. 
     Optionally, the determining a to-be-transmitted positioning reference signal includes determining at least one of the following: 
     an identifier (ID) or group ID of the positioning reference signal; 
     a transmission time of the positioning reference signal; 
     a transmission period of the positioning reference signal; 
     a quantity of transmission times of the positioning reference signal; 
     a time frequency resource of the positioning reference signal; 
     a quantity of the positioning reference signal; 
     a spatial relation of the positioning reference signal; 
     power information of the positioning reference signal; or 
     transmitting or stopping transmitting the positioning reference signal. 
     The time frequency resource includes, but is not limited to: a quantity of symbols, a time offset, frequency domain information (such as a frequency domain reference point pointA, a bandwidth (BW), a comb structure comb, a frequency domain offset, frequency hopping information, and the like). The quantity of the to-be-transmitted positioning reference signal may be a quantity of resources, or a quantity of resource sets (resource set). 
     Optionally, in this embodiment, the to-be-transmitted positioning reference signal is determined according to at least one of the following: 
     pre-configured configuration information of the positioning reference signal; 
     pre-defined configuration information of the positioning reference signal; 
     dynamically scheduled configuration information of the positioning reference signal; or 
     the first signaling. 
     Herein, the first signaling indicates the to-be-transmitted positioning reference signal by carrying the configuration information of the positioning reference signal or through a correspondence with the configuration information of the positioning reference signal. In this way, the target cell may directly transmit the positioning reference signal based on the pre-configured configuration information of the positioning reference signal, may directly transmit the positioning reference signal based on the pre-defined configuration information of the positioning reference signal, may directly transmit the positioning reference signal based on the dynamically scheduled configuration information of the positioning reference signal, and may directly transmit the positioning reference signal based on the first signaling. Certainly, configuration information of the to-be-transmitted positioning reference signal may also be determined through at least two of the pre-configured configuration information of the positioning reference signal, the pre-defined configuration information of the positioning reference signal, the dynamically scheduled configuration information of the positioning reference signal, or the first signaling, so as to complete the transmission of the positioning reference signal. 
     Example 1. The target cell transmits the positioning reference signal according to the configuration information (such as the transmission time, the transmission period, the quantity of transmission times, the quantity, the spatial relation, the time frequency resource, or the power information) of the positioning reference signal pre-configured by the LMF or the network-side device. 
     Example 2. A network side configures N1 positioning reference signals (such as aperiodic or on demand PRSs), and then may determine to transmit M1 aperiodic PRS(s) in the N1 aperiodic PRSs with reference to the first signaling, where M1 is an integer, and 1≤M1≤N1. Certainly, what is also determined may also include at least one of the transmission time, the transmission period, the quantity of transmission times, the time frequency resource, or the power information. 
     Example 3. A network side configures N2 positioning reference signals (such as aperiodic or on demand PRSs), and then may determine to transmit M2 aperiodic PRS(s) in the N2 aperiodic PRSs with reference to the first signaling and the configuration information of the positioning reference signal pre-defined by the network side or the configuration information of the positioning reference signal pre-configured by the LMF, where M2 is an integer, and 1&lt;M2&lt;N2. Certainly, what is also determined may also include at least one of the transmission time, the transmission period, the quantity of transmission times, the time frequency resource, or the power information. 
     Optionally, the first signaling includes at least one of the following: 
     a physical random access channel PRACH signal; 
     a sounding reference signal SRS; 
     uplink control information UCI; 
     a target signal whose signal feature meets a second preset condition; or 
     a first target uplink resource. 
     Certainly, the first signaling includes, but is not limited to: the physical random access channel (PRACH) signal, the channel sounding reference signal (SRS), the uplink control information (UCI), the target signal whose signal feature meets the second preset condition, and the first target uplink resource. 
     In this way, if the PRACH signal being the first signaling is used as an example, in the example 2 of determining the to-be-transmitted positioning reference signal, at least one of the following may be performed: 
     a1) determining a corresponding positioning reference signal (such as an aperiodic or on demand PRS) according to correspondences between root sequences of different PRACHs and positioning reference signals (such as aperiodic or on demand PRSs); 
     b1) determining a corresponding positioning reference signal (such as an aperiodic or on demand PRS) according to a RO (PRACH Occasion) resource in a current PRACH sequence; or 
     c1) determining a corresponding positioning reference signal (such as an aperiodic or on demand PRS) according to uplink information carried by a RO resource. 
     Herein, if a corresponding positioning reference signal (such as an aperiodic or on demand PRS) is jointly determined according to a1) and b1), for example: an index of a first positioning reference signal (such as an aperiodic or on demand PRS) is determined according to a1), and a target transmission occasion of the positioning reference signal (such as the aperiodic or on demand PRS) is determined according to b1), the target cell may transmit the first PRS at the target transmission occasion. 
     In the example 3 of determining the to-be-transmitted positioning reference signal, at least one of the following may be performed: 
     a2) determining, in a current PRACH sequence, a specific preamble (preamble) sequence (for example, being generated according to a specific root sequence, or specific preambles (that is, few preambles in 64 preambles) for activating the transmission of the positioning reference signal (such as the aperiodic or on demand PRS); 
     b2) determining, in a current PRACH sequence, a specific resource (such as a predetermined random access occasion RO resource for transmitting a target random access preamble sequence) for activating the transmission of the positioning reference signal (such as the aperiodic or on demand PRS), where the predetermined RO resource is dynamically configured in the configuration information transmitted by the network side, or pre-defined; or 
     c2) determining a corresponding positioning reference signal (such as an aperiodic or on demand PRS) according to uplink information carried by a RO resource. 
     Herein, if a corresponding positioning reference signal (such as an aperiodic or on demand PRS) is jointly determined according to a2) and b2), for example: an index of a second positioning reference signal (such as an aperiodic or on demand PRS) is determined according to a2), and a target transmission occasion of the positioning reference signal (such as the aperiodic or on demand PRS) is determined according to b2), the target cell may transmit the second positioning reference signal (such as the aperiodic or on demand PRS) at the target transmission occasion. 
     The target transmission occasion of the first positioning reference signal or the second positioning reference signal may be determined according to an activation time T1 and a time offset T2, for example, the target transmission occasion (the transmission time) is T1+T2. Herein, T2 may be a fixed value that is configured based on a capability of the terminal, configured based on a capability of the network side, or predefined; and may also be a variable, for example, T2 changes according to configuration of the first signaling (such as the resource or the root sequence). In this embodiment, the transmission occasion is not limited to the transmission time, and also includes the quantity of transmission times, the transmission period, and the like. 
     Certainly, the implementation of the PRACH signal being used as the first signaling is also applicable to the SRS, the UCI, the target signal whose signal feature meets the second preset condition, and the first target uplink resource. Details are not described herein again. 
     In this embodiment, in addition to being directly used as the first signaling, the first target uplink resource may be used for determining the to-be-transmitted positioning reference signal in consideration of configuration information of the first signaling. Optionally, the first signaling may be used as the first signaling by the first target uplink resource carrying the configuration information of the first signaling and with reference to the first target uplink resource and at least one of the PRACH signal, the SRS, the UCI, or the target signal whose signal feature meets the second preset condition. For example, the first signaling includes the PRACH signal and the first target uplink resource carrying configuration information of the PRACH signal for implementation. 
     In this embodiment, optionally, the PRACH signal includes one or more PRACH signals;

     there is a correspondence between configuration information of the PRACH signal and the positioning-related signal; or 
     there is a correspondence between a transmission resource of the PRACH signal and the positioning-related signal. 
     Herein, for the PRACH signal used as the first signaling, if a current target cell is a plurality of cells, in a case that random access channel (RACH) resources or configuration information of the plurality of cells are consistent, one preamble sequence and a same resource are used as the first signaling to be transmitted to the plurality of cells, that is, the first signaling corresponding to the plurality of cells is the same; in a case that the plurality of cells have overlapping RACH resources, one preamble sequence and a same resource are similarly used as the first signaling to be transmitted to the plurality of cells, that is, the first signaling corresponding to the plurality of cells is the same; and in a case that a RACH resource or configuration of a cell in the plurality of cells is different from those of other cells, for the cell different from other cells, a single preamble sequence is used as the first signaling to be transmitted to the cell. The preamble sequence may be pre-determined (pre-defined) for activating or deactivating the positioning-related signal, for example, may be a dedicated preamble sequence. 
     To transmit the PRACH signal to the plurality of cells, the UE needs to obtain configuration information of PRACH signals of the plurality of cells, where the configuration information is optionally transmitted by the serving cell or obtained by monitoring of the UE.

     a resource set pre-defined by a protocol; 
     a resource set capable of being preempted by the target signal; or 
     a dynamically scheduled resource set. 
     The target resource set meets at least one of the following: 
     a bandwidth of the target resource is fixed or corresponds to a bandwidth part (bandwidth part, BWP); 
     a center frequency of the target resource is fixed or corresponds to a BWP; 
     a comb structure Comb of the target resource is fixed or meets a third preset condition; 
     a frequency domain offset of the target resource is fixed or meets a fourth preset condition; or 
     a time domain location of the target resource is fixed or corresponds to a candidate resource. 
     In this way, the first signaling may use a specific radio information management (RIM) signal. If the time domain location of the transmission resource of the target signal is fixed, the time domain location may be a boundary slot of time division duplexing (TDD), and the candidate resource is a resource scheduled for the terminal. Both the third preset condition and the fourth preset condition are that the Comb is consistent with the frequency domain offset. Certainly, the third preset condition and the fourth preset condition may also be other settings. 
     Alternatively, for the target signal being the Zadoff-Chu (ZC) sequence, ZC cyclic shifting indicates whether to activate, or which positioning-related signal is activated. 
     In this embodiment, optionally, the second signaling includes at least one of the following: 
     a target signal whose signal feature meets a first preset condition; 
     Xn interface information; 
     downlink control information (DCI); 
     a target downlink resource; or 
     Long Term Evolution Positioning Protocol A LPPa or New Radio Positioning Protocol A NRPPa information. 
     Herein, the second signaling may be transmitted by the serving cell to the neighboring cell, or be transmitted by the serving cell to the location management device such as the LMF. Moreover, the second signaling is used for activating or deactivating the receiving of the positioning reference signal by the terminal, and may also be transmitted by the serving cell to the terminal. Therefore, the implementation of the second signaling includes, but is not limited to, at least one of the target signal whose signal feature meets the first preset condition, the Xn interface information, the DCI, the target downlink resource, or the LPPa or NRPPa information. Certainly, the LMF may also transmit signaling to activate or deactivate the receiving of the positioning reference signal by the terminal. 
     The target signal that may be used as the second signaling may be the same as the above target signal used as the first signaling, that is, the first preset condition is the same as the second preset condition. In this way, the limitation on the target signal used as the first signaling is also applicable to the target signal used as the second signaling. However, for the target signal used as the second signaling, if there is the correspondence between the target signal and the positioning-related signal, there is the correspondence between the configuration information of the target signal and the positioning-related signal, there is the correspondence between the transmission resource of the target signal and the positioning-related signal, or there is a limitation related to the positioning-related signal, the positioning-related signal is the positioning reference signal. For the target signal used as the second signaling, the candidate resource is a resource scheduled for the neighboring cell. 
     In addition, the target signal used as the second signaling and whose signal feature meets the first preset condition may also include, but is not limited to: at least one of a larger delay, a larger path loss, being different from a signal currently measured by the terminal, and carrying identification information of a transmitting cell, or a quantity of detectable second signaling within a preset time. In consideration of a distance of the neighboring cell, the target signal needs a larger delay, such as transmitting two continuous symbols, using an extended cyclic prefix (CP), or using a smaller subcarrier spacing. Transmitting two continuous symbols may refer to aggregating CPs of the two symbols to a first symbol, or may also mean that phases between the symbols are continuous. In consideration of the distance of the neighboring cell, the target signal needs a larger path loss. The target signal is different from the signal currently measured by the terminal, and may be designed according to configuration and a sequence of the signal. The identification information of the transmitting cell carried by the target signal may be identification information (such as a group ID) of a group, that is, group IDs carried by second signaling in a specific area are the same. Herein, the group ID may be indicated or pre-defined by the LMF and constrained by an area ID or areascop. Further, one serving cell may also have i group IDs, and i is optionally 1, 2, 4, 8, or 16, and an upper limit thereof is optionally 128, 256, 1024, 4096, or 65536. The identification information of the transmitting cell carried by the target signal includes: time division, that is, dividing different cells according to different time domain locations; frequency division, that is, dividing different cells according to different frequency domain locations; and code division, that is, dividing different cells according to different RS sequences. 
     In this embodiment, optionally, the first target uplink resource meets at least one of the following: 
     the first target uplink resource carries configuration information of the positioning-related signal; 
     information carried by the first target uplink resource is capable of being parsed by a physical layer; 
     there is a correspondence between configuration information of the first target uplink resource and the positioning-related signal; 
     there is a correspondence between a transmission resource of the first target uplink resource and the positioning-related signal; or 
     there is a correspondence between the first target uplink resource and a transmission time of the positioning-related signal. 
     Herein, the first target uplink resource may be individually used as the first signaling; and may also be a specific uplink resource matching a signal of the first signaling, to transmit or receive the signal of the first signaling and/or the configuration information of the positioning-related signal. Because the information carried by the first target uplink resource may be parsed, the positioning reference signal that needs to be transmitted is optionally determined with reference to the information carried by the first target uplink resource and an identifier of a receiving cell (or the pre-configured information of the positioning reference signal), and certainly, values of X and Y may also be determined. 
     As shown in  FIG.  3   , the first signaling includes a signal sequence  301  and a first target uplink resource  302  carrying the configuration information of the positioning-related signal, and activates transmission of a positioning-related signal  303  by the target cell after X+Y*14 symbols. A time between the first signaling and the positioning-related signal may use a symbol as a unit, or may also use a slot or the like. 
     The configuration information of the positioning reference signal includes, but is not limited to: a frequency layer ID, a pointA, a subcarrier spacing (SCS), a comb size, starting location information of the positioning reference signal, bandwidth information of the positioning reference signal, numerology (numerology) information of the positioning reference signal, a frequency band (band) identifier, and time domain information of the positioning reference signal. The time domain information includes, but is not limited to: a time domain location, a period, a periodic offset, a transmission occasion, and repeated information. 
     If the first signaling is like an SSB (further carrying physical broadcast channel (PBCH) information in addition to a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)), the first signaling may use at least one symbol for activating or deactivating the transmission of the positioning-related signal and/or carry indication information (such as an identification identifier, and 1-bit information) for activating or deactivating. There are N5 symbols for the transmission of the signal and N6 symbols for carrying configuration information in the first signaling. The configuration information may be information for performing key protection or scrambling on an identification identifier or other security identifiers. 
     In this embodiment, activating or deactivating transmission of an identification identifier or a security key of the positioning-related signal may be configured by the network-side device or the location management device such as the LMF. The neighboring cell may be pre-configured from the network side, or pre-configured through network deployment, or combinedly configured. 
     In addition, in this embodiment, the implementation of the first target uplink resource is also applicable to a target downlink resource. Details are not described herein again. 
     In addition, optionally, the method further includes: 
     transmitting the configuration information of the positioning-related signal through a second target uplink resource. 
     Herein, the second target uplink resource is a resource dedicatedly used for transmitting the configuration information of the positioning-related signal. 
     In this embodiment, the configuration information of the first signaling may be configured by the network-side device or the LMF. Therefore, optionally, the method further includes: 
     receiving configuration information of the first signaling transmitted by a location management device or a network-side device, where the configuration information of the first signaling includes at least one of the following: 
     a type of the signaling; 
     an identifier ID or group ID of the signal; 
     a transmission time of the signal; 
     a transmission period of the signal; 
     a quantity of transmission times of the signal; 
     a time domain resource of the signal; 
     a quantity of the signal; 
     a spatial relation of the signal; 
     power information of the signal; 
     transmitting or stopping transmitting the first signaling; or a correspondence with the positioning-related signal. 
     Herein, it may be learned from the above that, the type of the first signaling may include the PRACH signal, a signal dedicatedly used for activating or deactivating (such as the SRS or the target signal), or other uplink signals (the UCI and a signal of the first target uplink resource). The correspondence with the positioning-related signal may be that: the first signaling activates or deactivates all specific positioning-related signals respectively corresponding to the first signaling. 
     Certainly, configuration information corresponding to the second signaling, the PRACH signal, the SRS, the UCI, the first target uplink resource, and the like may be similar to that of the above first signaling. Details are not described herein again. 
     It should be noted that, the first signaling and the second signaling may determine the to-be-transmitted positioning-related signal with reference to the second target uplink resource and/or the first target uplink resource, and the second signaling may also determine the to-be-transmitted positioning-related signal with reference to the second target uplink resource and/or the target downlink resource. 
     In this embodiment, for the transmission occasion of the positioning reference signal and the signaling used for activating or deactivating (such as the first signaling or the second signaling), the signaling used for activating or deactivating may also be used for information exchange (such as: successfully activating). 
     Optionally, the target cell feeds back for the first signaling after receiving the first signaling. Therefore, after the transmitting first signaling to a target cell, the method further includes: 
     receiving first feedback information of the target cell, where the first feedback information is used for indicating at least one of the following: 
     whether the transmission of the positioning-related signal is successfully activated or deactivated; or 
     whether the first signaling is successfully received. 
     The first feedback information received by the terminal indicates whether the transmission of the positioning-related signal is successfully activated or deactivated and/or whether the first signaling is successfully received. 
     The first feedback information may be interacted through UU signaling, such as transmitted in a random access response (RAR), and the above indication is performed through information of one or more bits of the RAR. The information may use uplink grant UL grant, a cell-radio network temporary identifier (C-RNTI) (all 0 or all 1), or the like. In another example, the first feedback information is a random access preamble identifier (RAPID), which is a preamble index obtained when a gNB detects a preamble. If the terminal discovers that the RAPID received by the terminal is the same as an index used when the terminal transmits a preamble (if the preamble is specified by positioning, it is considered that an on demand PRS is successfully activated), it is considered that a corresponding RAR is successfully received, and a corresponding RAPID medium access control (MAC) subheader is formed by three fields (E/T/RAPID). 
     The first feedback information may also detect the received positioning-related signal to determine whether to activate or deactivate the estimated positioning-related signal. 
     However, it may be learned from the above embodiments that, the serving cell may transmit the second signaling to the neighboring cell, and then the neighboring cell may feed back information to the serving cell, such as perform X2 signaling interaction, or transmit signaling to the LMF. The LMF collects feedback information of all related neighboring cells, and transmits neighboring cells that perform determining acknowledgement (ACK) or neighboring cells that perform negative acknowledgement (NACK) to the serving cell. In this case, the feedback information of the neighboring cell also indicates whether the transmission of the positioning reference signal is successfully activated or deactivated and/or whether the second signaling is successfully received. In addition, the feedback information of the neighboring cell may implement the above first feedback information. Details are not described herein again. 
     In addition, the cell that receives the first signaling and/or the second signaling may also feed back to the LMF that: the cell notifies the LMF that the cell activates or deactivates the corresponding signal through single signaling exchange. When the cell performs other signaling interaction, the cell carries feedback information of the cell to the LMF, to notify the cell to activate or deactivate the corresponding signal. Alternatively, an activated or deactivated signal ID, an activated or deactivated source device, or the like may be fed back. 
     In this embodiment, optionally, the target cell is determined in at least one of the following manners: 
     configuration of a network side; 
     a monitoring result of the terminal; or 
     a measurement result of radio resource management (Radio Resource Management, RRM). 
     In addition, for the target cell, in addition to activating or deactivating the transmission of the positioning-related signal by the target cell through the first signaling of the terminal, the transmission of the positioning-related signal by the target cell may also be activated or deactivated through third signaling of the LMF. Therefore, after receiving the third signaling of the LMF, the transmission of the positioning-related signal by the target cell is activated or deactivated. 
     Same as the first signaling, in a case that the target cell is the serving cell and the neighboring cell or the target cell is the neighboring cell, the third signaling is used for activating or deactivating the transmission of the positioning reference signal by the target cell; and in a case that the target cell is the serving cell, the third signaling is used for activating or deactivating the transmission of the second signaling and the positioning reference signal by the target cell. 
     Moreover, the target cell receives configuration information of the third signaling transmitted by the LMF; or, transmits the configuration information of the third signaling to the LMF. The configuration information of the third signaling includes at least one of the following: 
     a type of the signaling; 
     an identifier ID or group ID of the signal; 
     a transmission time of the signal; 
     a transmission period of the signal; 
     a quantity of transmission times of the signal; 
     a time domain resource of the signal; 
     a quantity of the signal; 
     a spatial relation of the signal; 
     power information of the signal; 
     transmitting or stopping transmitting the third signaling; or 
     a correspondence with the positioning-related signal. 
     In this way, the configuration information of the third signaling is similar to the configuration information of the first signaling. Details are not described herein again. 
     Optionally, the third signaling includes: 
     NRPPa information. 
     The cell that receives the third signaling may also feed back information to the LMF that: the cell notifies the LMF that the cell activates or deactivates the corresponding signal through single signaling exchange. When the cell performs other signaling interaction, the cell carries feedback information of the cell to the LMF, to notify the cell to activate or deactivate the corresponding signal. Alternatively, an activated or deactivated signal ID, an activated or deactivated source device, or the like may be fed back. 
     In this embodiment, the terminal can activate the positioning reference signal transmitted by the serving cell and the positioning reference signal transmitted by the neighboring cell based on the first signaling or the third signaling, to perform positioning measurement, so as to obtain positioning information. 
     Application (using activating a PRS as an example) of the method in the embodiments of this application in different scenarios is described below with reference to the accompanying drawings. 
     Scenario 1. As shown in  FIG.  4   , a location server (Location Based Services, LBS) transmits a location request including a delay and a precision threshold to an LMF. Herein, the LMF configures PRS configuration information, and transmits the PRS configuration information to a serving cell and a neighboring cell for subsequent transmission of PRSs. The LMF may also transmit PRS configuration information to a terminal, for the terminal to subsequently measure the PRSs. The terminal transmits PRS activation signaling (namely, first signaling) to the serving cell and the neighboring cell, to activate transmission of PRSs by the serving cell and the neighboring cell. In this way, the terminal can measure the PRSs of the serving cell and the neighboring cell, so as to complete positioning. 
     The serving cell and the neighboring cell can also transmit feedback information to the terminal after receiving the PRS activation signaling, to indicate an activation situation and other information. 
     The LMF can also include PRS configuration information of PRS activation signaling (namely, third signaling), to activate the transmission of the PRSs by the serving cell and the neighboring cell. 
     Scenario 2. As shown in  FIG.  5   , a terminal performs a location service request, to request positioning that needs a low delay and high precision. Herein, an LMF configures PRS configuration information, and transmits the PRS configuration information to a serving cell and a neighboring cell for subsequent transmission of PRSs. The terminal transmits serving cell activation signaling (namely, first signaling) to the serving cell, to activate transmission of a PRS and PRS activation signaling (namely, second signaling) by the serving cell. The neighboring cell transmits a PRS based on the received PRS activation signaling. In this way, the terminal can measure the PRSs of the serving cell and the neighboring cell, so as to complete positioning. 
     The serving cell can also transmit PRS measurement activation signaling to the terminal, to notify the terminal to perform PRS measurement in time. The neighboring cell can also transmit feedback information to the serving cell after receiving the PRS activation signaling, to indicate an activation situation and other information. 
     The LMF can also include PRS configuration information of PRS activation signaling (namely, third signaling), to activate the transmission of the PRSs by the serving cell and the neighboring cell. 
     Scenario 3. As shown in  FIG.  6   , a terminal performs a location service request, to request positioning that needs a low delay and high precision. Herein, an LMF configures PRS configuration information, and transmits the PRS configuration information to a serving cell and a neighboring cell for subsequent transmission of PRSs. The terminal transmits serving cell activation signaling (namely, first signaling) to the serving cell, to activate transmission of a PRS and LMF activation signaling (namely, second signaling) by the serving cell. The LMF transmits PRS activation signaling to the neighboring cell based on the received LMF activation signaling. The neighboring cell transmits a PRS based on the received PRS activation signaling. In this way, the terminal can measure the PRSs of the serving cell and the neighboring cell, so as to complete positioning. 
     The serving cell can also transmit PRS measurement activation signaling to the terminal, to notify the terminal to perform PRS measurement in time. The serving cell can also transmit configuration information of PRS activation signaling, so that the neighboring cell receives the PRS activation signaling. The neighboring cell can also transmit feedback information to the serving cell after receiving the PRS activation signaling, to indicate an activation situation and other information. 
     The LMF can also include PRS configuration information of PRS activation signaling (namely, third signaling), to activate the transmission of the PRSs by the serving cell and the neighboring cell. 
     Scenario 4. A terminal performs a location service request, to request positioning that needs a low delay and high precision. The terminal transmits serving cell activation signaling (namely, first signaling) to the serving cell, to activate transmission of a PRS and LMF activation signaling (namely, second signaling) by the serving cell. An LMF transmits PRS activation signaling to the neighboring cell based on the received LMF activation signaling. The neighboring cell transmits a PRS based on the received PRS activation signaling. In this way, the terminal can measure the PRSs of the serving cell and the neighboring cell, so as to complete positioning. 
     Scenario 5. A location server (Location Based Services, LBS) transmits a location request including a delay and a precision threshold to an LMF. Herein, the LMF configures PRS configuration information, and transmits the PRS configuration information to a serving cell and a neighboring cell for subsequent transmission of PRSs. The LMF may also transmit PRS configuration information to a terminal, for the terminal to subsequently measure the PRSs. The LMF transmits PRS configuration information of PRS activation signaling (namely, third signaling), to activate transmission of PRSs by the serving cell and the neighboring cell. The LMF or the serving cell transmits second signaling to activate transmission of a positioning reference signal by the neighboring cell or activate receiving of the positioning reference signal by a UE. 
     In addition, the serving cell may transmit PRS activation signaling to the neighboring cell to activate transmission of a PRS by the neighboring cell when transmitting LMF activation signaling to the LMF. 
     In the above scenario, the configuration information may be interactively configured by devices of two sides, for example, the PRS configuration information may be configured by the serving cell to be transmitted to the LMF. 
     In summary, in the method in this embodiment of this application, a terminal transmits first signaling to a target cell, namely, a serving cell and/or a neighboring cell of the terminal, to directly activate or deactivate transmission of a positioning-related signal by the target cell, so as to reduce delays of positioning, thereby meeting the timeliness requirement for obtaining a positioning reference signal.
