[0039] To make the objectives, technical solutions, and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Exemplary embodiments will be described in detail herein, with examples shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0040] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems. The terms used in this disclosure are merely for the purpose of describing specific embodiments and are not intended to limit this disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0041] It should be understood that although the terms first, second, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter without departing from the scope of this disclosure. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0042] Some terms involved in the embodiments of this application are introduced as follows.

[0043] Perception refers to the use of radio waves to detect parameters of the physical environment to achieve environmental perception technologies such as target positioning, motion recognition, and imaging. The devices involved in perception include the following:

[0044] The perception signal sending device, or anchor point device, is a device that sends a sidelink reference signal in the embodiment of the present application;

[0045] The perception signal receiving device, in an embodiment of the present application, is a device that receives and measures a sidelink reference signal.

[0046] The relevant technical background involved in the embodiments of this application is introduced.

[0047] FIG1 shows a schematic diagram of a communication network architecture provided by an exemplary embodiment of the present application. The communication network architecture may include: a core network 11 , an access network 12 , and a terminal 13 .

[0048] The core network 11 includes several core network devices. The functions of the core network devices are mainly to provide user connections, user management, and service carrying, and to provide an interface to the external network as a bearer network. For example, the core network of the fifth generation mobile communication technology (5th Generation, 5G) New Radio (NR) system may include devices such as the Access and Mobility Management Function (AMF) entity, the User Plane Function (UPF) entity, and the Session Management Function (SMF) entity.

[0049] The access network 12 includes several access network devices 14. The access network in the 5G NR system can be called a new generation radio access network (NG-RAN). The access network device 14 is a device deployed in the access network 12 to provide wireless communication functions for the terminal 13. The access network device 14 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR system, it is called a 5G base station (Next Generation Node B, gNodeB or gNB). With the evolution of communication technology, the name of "access network device" may change. For the convenience of description, in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the terminal 13 are collectively referred to as access network devices.

[0050] There are usually multiple terminals 13, and one or more terminals 13 can be distributed in the cell managed by each access network device 14. The terminal 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile stations (MS), etc. For the convenience of description, the devices mentioned above are collectively referred to as terminals. The access network device 14 and the core network device communicate with each other through some air technology, such as the NG interface in the 5G NR system. The access network device 14 and the terminal 13 communicate with each other through some air technology, such as the Uu interface.

[0051] Terminals 13 and 13 (for example, vehicle-mounted equipment and other equipment (such as other vehicle-mounted equipment, mobile phones, road side units (RSU)), etc.)) can communicate with each other through a direct communication interface (such as a PC5 interface). Accordingly, the communication link established based on the direct communication interface can be called a direct link or a side link (SL). SL transmission is the direct communication and data transmission between terminals through a side link. Unlike traditional cellular systems in which communication data is received or sent through access network equipment, SL transmission has the characteristics of short delay and low overhead, and is suitable for communication between two terminals with close geographical locations (such as vehicle-mounted equipment and other peripheral devices with close geographical locations). SL technology can be applied to scenarios where various terminals communicate directly, such as vehicle-to-vehicle communication in a V2X scenario. In other words, the terminal in this application refers to any device that communicates using SL technology. The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, and those skilled in the art may understand its meaning. The technical solution described in the embodiments of the present disclosure may be applicable to the 5G NR system, and may also be applicable to subsequent evolution systems of the 5G NR system. In the embodiments of the present disclosure, UE and terminal have the same meaning and can be replaced with each other.

[0052] Since the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring, future cellular networks can be considered not only for communication and data transmission but also for acquiring sensory information.

[0053] Currently, discussions are underway to support sensing capabilities in B5G networks. This will be achieved by adding a sensing control element (SF) and corresponding processes to 3GPP networks. In implementing sensing functions, sensing measurements can be divided into active sensing and passive sensing, depending on the sensing target. Active sensing targets the UE, meaning it's UE-level sensing. Passive sensing targets the target area or object, meaning it's area-level sensing. It doesn't involve a specific UE and isn't part of the 3rd Generation Partner Project (3GPP).

[0054] As the spectrum for wireless communications and sensing gradually overlap, integrated communication and sensing technology merges these two functions, leveraging wireless resources to implement sensing. As shown in Figure 2, wireless sensing scenarios for integrated communication and sensing include at least one of the following eight modes.

[0055] Mode 1: Base station autonomous sensing. In Mode 1, the sensing signal transmitter and receiver are the same base station. Specifically, the base station transmits a sensing signal to the sensing target. After the sensing signal is reflected by the sensing target, the same base station receives the reflected signal (i.e., the sensing signal after being reflected by the sensing target).

[0056] Mode 2: Terminals transmit and receive sensing independently. In Mode 2, the sensing signal transmitter and receiver are the same terminal. That is, the terminal sends a sensing signal to the sensing target, which is then reflected by the sensing target and then received by the same terminal.

[0057] Mode 3: Base station cooperative sensing. In Mode 3, the sensing signal transmitter and the sensing receiver are different base stations. That is, one base station sends a sensing signal to the sensing target, which is then reflected by the sensing target and received by another base station.

[0058] Mode 4: Terminal cooperative sensing. In Mode 4, the sensing signal sending device and the sensing receiving device are different terminals. That is, one terminal sends a sensing signal to the sensing target, and after the sensing signal is reflected by the sensing target, another terminal receives the reflected signal.

[0059] Mode 5: Base station-terminal collaborative sensing. In Mode 5, the sensing signal transmitter is the base station, and the sensing receiver is the terminal. Specifically, the base station transmits a sensing signal to the sensing target, which is then reflected by the sensing target and received by the terminal.

[0060] Mode 6: Terminal-Base Station Collaborative Sensing. In Mode 6, the terminal is the sensing signal transmitter, and the base station is the sensing receiver. Specifically, the terminal sends a sensing signal to the sensing target, which is then reflected by the sensing target and received by the base station.

[0061] Mode 7: The sensing target is the sensing signal transmitting device. In Mode 7, the sensing signal transmitting device is the terminal, and the sensing receiving device is the base station. Since the sensing target (terminal) is the sensing signal transmitting device, the sensing signal is sent from the sensing signal transmitting device (terminal) to the sensing receiving device (base station) without reflection. The base station can directly receive and interpret the sensing result.

[0062] Mode 8: The sensing target is the sensing receiving device. In Mode 8, the sensing signal transmitting device is the base station, and the sensing receiving device is the terminal. Since the sensing target (terminal) is the sensing receiving device, after receiving the sensing signal, the terminal needs to feed back the sensing result to the base station so that the base station can obtain the sensing result.

[0063] There is a sidelink perception method in which the target UE measures the SL-PRS sent by the anchor UE, obtains the measurement result, and then returns the measurement result to the anchor UE to complete the wireless perception.

[0064] In actual applications, the UE is mobile. When the terminal's moving distance is greater than a certain threshold, the terminal will no longer be able to detect the SL-PRS sent by the previously configured anchor terminal due to signal attenuation.

[0065] Introduce the perception scene.

[0066] Communication sensing involves a base station or terminal sending communication signals to detect and estimate a target, determining its presence and estimating its speed, distance, and direction of arrival. The target can be a person or an object, enabling functions such as detecting human intrusion, movement, or falls, posture recognition, and creating a three-dimensional image of the object. The communication sensing method provided in this application can be applied to the following two sensing scenarios.

[0067] The first perception scenario: the perception signal receiving terminal moves in the same direction as the target.

[0068] In at least two areas and / or time windows, at least two sensing signal receiving terminals participate in the sensing measurement; that is, different sensing signal transmitting terminals participate in the sensing measurement in different areas and / or time windows. In at least two areas and / or time windows, different SL-PRS configurations are used for the sensing measurement.

[0069] For example, the network architecture for the first perception scenario can be shown in Figures 3 and 4. In Figure 3, an absolutely stationary perception signal transmitting terminal 21 transmits an SL-PRS on a sidelink, and a perception signal receiving terminal 23 measures the SL-PRS and perceives a target 22 in the environment, which moves in the same direction as the perception signal receiving terminal 23. In Figure 4, a mobile perception signal transmitting terminal 31 transmits an SL-PRS on a sidelink, and a perception signal receiving terminal 33 measures the SL-PRS and perceives a target 32 ​​in the environment, which moves in the same direction as the perception signal receiving terminal 33.

[0070] The second perception scenario: in different areas and / or time windows, the perception signal receiving terminal performs perception measurements on different targets.

[0071] The position of the target is fixed, but the position of the sensing signal receiving terminal changes. The sensing signal receiving terminal performs sensing measurements on different targets based on different SL-PRS configurations in different areas and / or time windows.

[0072] For example, the network architecture for the second perception scenario can be shown in Figures 5 and 6. In Figure 3, a stationary perception signal transmitting terminal 41 transmits an SL-PRS on a sidelink, and a perception signal receiving terminal 43 measures the SL-PRS to perceive an absolutely stationary target 42 in the environment. In Figure 6, a mobile perception signal transmitting terminal 51 transmits an SL-PRS on a sidelink, and a perception signal receiving terminal 53 measures the SL-PRS to perceive an absolutely stationary target 52 in the environment.

[0073] FIG7 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application. The method is performed by a first terminal, and the method includes:

Exemplarily, the first terminal determines the SL-PRS configuration associated with the first region, and determines the first SL-PRS based on the SL-PRS configuration associated with the first region.

[0083] For example, at least two time windows include time window 1 and time window 2, time window 1 is associated with SL-PRS configuration 21, and time window 2 is associated with SL-PRS configuration 22; in time window 1, the first terminal determines the SL-PRS configuration 21 associated with time window 1, and determines the SL-PRS based on the SL-PRS configuration 21; in time window 2, the first terminal determines the SL-PRS configuration 22 associated with time window 2, and determines the SL-PRS based on the SL-PRS configuration 22.

[0084] Optionally, the association information includes a region and a time window; at least two region and time window combinations are associated with different SL-PRS configurations.

Exemplarily, the first terminal determines an SL-PRS configuration associated with the first region and the first time window, and determines a first SL-PRS based on the SL-PRS configuration associated with the first region and the first time window.

[0087] Optionally, each time window corresponds to one or more time windows. When a time window corresponds to multiple regions, the multiple regions within the time window are associated with different SL-PRS configurations. For example, if time window 1 corresponds to region 1 and region 2, region 1 and time window 1 are associated with SL-PRS configuration 31, and region 2 is associated with time window 1 with SL-PRS configuration 34.

[0088] Optionally, the region in the association information is represented by at least one of the following:

[0094] Optionally, the SL-PRS configuration includes: an SL-PRS group consisting of at least two SL-PRSs; or an auxiliary message containing at least two SL-PRSs. Exemplarily, the first terminal determines the first SL-PRS from the SL-PRS group associated with the first association information; or determines the first SL-PRS from the at least two SL-PRSs contained in the auxiliary message associated with the first association information.

[0095] The first terminal is a perception signal receiving terminal. Optionally, the first terminal is also a perception initiating device or a perception responding device.

[0096] Step 602: Perform perception measurement using the first SL-PRS according to the first association information.

[0097] The first terminal performs perception measurement on the sidelink using the first SL-PRS according to the first association information. Exemplarily, the first terminal receives and measures the first SL-PRS on the sidelink according to the first association information.

[0098] Optionally, the first association information includes a first area; after the first terminal determines the first SL-PRS associated with the first area, the first terminal performs perception measurement through the first SL-PRS in the first area.

[0162] The sl-PRS-ResourcePrioritySubset field provides a subset of SL-PRS resources that is associated with the nr SL PRS resource ID for the purpose of SL AoD reporting priority. This field is only applicable to the SL-AoD (Angle-of-Departure) positioning method and should be ignored for SL-TDoA (Time Difference of Arrival) and Multi-RTT (Round Trip Time) positioning methods.

[0163] Exemplarily, the network device configures an SL-PRS configuration associated with at least two pieces of association information for the first terminal through the at least one field.

[0164] Step 702: The first terminal receives at least two pieces of association information configured by a network device, and at least two groups of SL-PRS configurations corresponding to the at least two pieces of association information.

[0165] Optionally, the first terminal receives at least two association information initially configured by the network device, and at least two groups of SL-PRS configurations corresponding to the at least two association information; or, the first terminal receives at least two association information updated by the network device, and at least two groups of SL-PRS configurations corresponding to the at least two association information.

[0166] To sum up, the pre-configuration method provided in this embodiment pre-configures at least two pieces of associated information and different SL-PRS configurations associated with at least two pieces of associated information for the first terminal, so that after entering an area and / or time window, the first terminal can determine the SL-PRS to be sensed and measured based on the SL-PRS configuration associated with the pre-configured area and / or time window, without requesting the SL-PRS configuration from the network, thereby reducing the signaling interaction between the first terminal and the network after entering different areas and / or time windows, and reducing the latency of the wireless sensing service.

[0167] When the associated information is an area, after leaving the first area and entering the second area, the first terminal needs to determine the second SL-PRS associated with the second area based on the association relationship between the area and the SL-PRS configuration, and then perform perception measurement through the second SL-PRS.

[0168] After entering the second area and before performing perception measurement through the second SL-PRS, the first terminal further requests to update the configuration of the SL-PRS.

[0169] In some embodiments, the first terminal requests the network device to update the configuration of the SL-PRS in order to request the network device to coordinate the work of the anchor terminals in the first area and / or the second area.

[0170] In some other embodiments, the first terminal requests the network device to update the configuration of the SL-PRS in order to request the network device to update the configuration of the SL-PRS associated with the second area.

[0171] In the case of requesting the network device to coordinate the work of the anchor terminal, the interaction process between the first terminal and the network device includes:

[0172] The first terminal sends a message to the network device for requesting to update the SL-PRS configuration. The message for requesting to update the SL-PRS configuration carries relevant information of the first terminal, that is, after entering the second area, the first terminal reports relevant information of the first terminal.

Taking the first terminal reporting the above-mentioned related information to the network device as an example, these two situations are described respectively.

[0178] For the first case, as shown in FIG9 , which is a perception measurement process of a first terminal in a second area provided by an exemplary embodiment, the steps are as follows:

A first terminal has at least two regions and different SL-PRS configurations associated with the at least two regions; the first terminal determines a second SL-PRS associated with a second region of the at least two regions. Exemplarily, the first terminal determines the SL-PRS configuration associated with the second region, and determines the second SL-PRS based on the SL-PRS configuration associated with the second region.

[0192] Optionally, the region in the association information is represented by at least one of the following: RNA; TA; SSB; cell.

[0193] Optionally, the SL-PRS configuration includes: an SL-PRS group consisting of at least two SL-PRSs; or an auxiliary message containing at least two SL-PRSs. Exemplarily, the first terminal determines the second SL-PRS from the SL-PRS group associated with the second area; or determines the second SL-PRS from at least two SL-PRSs contained in the auxiliary message associated with the second area.

[0194] Step 806: The first terminal performs perception measurement using the second SL-PRS in the second area.

[0195] For the second case, as shown in FIG10 , which is a perception measurement process of a first terminal in a second area provided by an exemplary embodiment, the steps are as follows:

[0196] Step 901: A first terminal sends a message for requesting to update the SL-PRS configuration. The message for requesting to update the SL-PRS configuration carries relevant information of the first terminal.

[0197] After entering the second area, the first terminal determines relevant information about the first terminal and reports the relevant information about the first terminal to the network device. For example, after entering the second area, the first terminal confirms its own location and reports its location to the network device; for another example, after entering the second area, the first terminal reports area information of the second area to the network device; for another example, after entering the second area, the first terminal determines a second SL-PRS associated with the second area based on the association between the area and the SL-PRS configuration, and reports information about the second SL-PRS to the network device.

[0198] Optionally, the message for requesting to update the SL-PRS configuration includes an SL-PRS configuration update request message, and the relevant information of the first terminal is carried in the SL-PRS configuration update request message. Exemplarily, the first terminal sends the SL-PRS configuration update request message, and the SL-PRS configuration update request message carries the relevant information of the first terminal.

[0199] Step 902: The network device receives a message from the first terminal requesting to update the SL-PRS configuration.

[0200] The network device obtains relevant information of the first terminal carried in the message for requesting to update the SL-PRS configuration.

[0201] The relevant information of the first terminal is reported after the first terminal enters the second area. Exemplarily, the relevant information of the first terminal is reported after the first terminal leaves the first area and enters the second area.

[0202] Optionally, the network device receives an SL-PRS configuration update request message sent by the first terminal.

[0203] Step 903: The first terminal determines a second SL-PRS associated with the second area.

[0204] At least two regions are associated with different SL-PRS configurations. A first terminal has at least two regions and different SL-PRS configurations associated with the at least two regions; the first terminal determines a second SL-PRS associated with a second region of the at least two regions. Exemplarily, the first terminal determines the SL-PRS configuration associated with the second region, and determines the second SL-PRS based on the SL-PRS configuration associated with the second region.

[0205] Optionally, the region in the association information is represented by at least one of the following: RNA; TA; SSB; cell.

[0206] Optionally, the SL-PRS configuration includes: an SL-PRS group consisting of at least two SL-PRSs; or an auxiliary message containing at least two SL-PRSs. Exemplarily, the first terminal determines the second SL-PRS from the SL-PRS group associated with the second area; or determines the second SL-PRS from at least two SL-PRSs contained in the auxiliary message associated with the second area.

[0207] Step 904: The first terminal performs perception measurement using a second SL-PRS in the second area.

[0208] Exemplarily, in the two embodiments shown in FIG9 and FIG10 , after receiving the reported relevant information of the first terminal, the network device may perform at least one of the following steps:

[0209] • Activate a second SL-PRS associated with the second area.

[0210] Start sending the second SL-PRS.

[0211] Control the anchor terminal in the second area to enter the working state.

[0212] Control the anchor terminal associated with the second SL-PRS to operate.

[0213] The working state refers to a working state participating in the perception measurement of the second SL-PRS signal.

[0214] Exemplarily, after receiving the relevant information of the first terminal, the network device sends first indication information to the anchor terminal located in the second area based on the relevant information of the first terminal; or, after receiving the relevant information of the first terminal, sends the first indication information to the anchor terminal associated with the second SL-PRS. The first indication information is used to notify the anchor terminal to enable the second SL-PRS associated with the second area; and / or to notify the anchor terminal to start sending the second SL-PRS; and / or to notify the anchor terminal to enter a working state.

[0215] The network device contains at least two predefined or preconfigured areas for a first terminal, and SL-PRS configurations associated with the at least two areas. Based on the relevant information about the first terminal, the network device determines that the first terminal is located in the second area; sends first indication information to an anchor terminal in the second area. Alternatively, based on the relevant information about the first terminal, the network device determines that the first terminal is located in the second area; determines a second SL-PRS associated with the second area; determines the anchor terminal associated with the second SL-PRS; and sends the first indication information to the anchor terminal associated with the second SL-PRS.

[0216] Optionally, there are at least two areas predefined or preconfigured for the first terminal in the anchor terminal, and SL-PRS configurations associated with at least two areas. In this case, the location of the first terminal or the area identifier of the second area can be carried in the above-mentioned first indication information, and the anchor terminal determines the second SL-PRS associated with the second area based on the location of the first terminal or the area identifier of the second area.

[0217] Optionally, there are no predefined or preconfigured at least two areas for the first terminal, and no SL-PRS configuration associated with at least two areas in the anchor terminal. In this case, information about the second SL-PRS may be carried in the above-mentioned first indication information, and the anchor terminal may determine the second SL-PRS based on the information about the second SL-PRS.

[0218] Exemplarily, the network device further receives third confirmation information sent by the anchor terminal in response to the first indication information, where the third confirmation information is used to report to the network device that the anchor terminal has enabled the second SL-PRS associated with the second area.

[0219] In some other embodiments, after receiving the reported relevant information of the first terminal, the network device may perform at least one of the following steps:

[0220] Deactivate a first SL-PRS associated with the first area.

[0221] ·Terminate the transmission of the first SL-PRS.

[0222] Control the anchor terminal in the first area to stop working.

[0223] Control the anchor terminal associated with the first SL-PRS to terminate operation.

[0224] The termination of the work refers to the termination of the perception measurement task of the first SL-PRS signal.

[0225] Exemplarily, after receiving relevant information about the first terminal, the network device sends second indication information to the anchor terminal in the first area; or, after receiving relevant information about the first terminal, sends second indication information to the anchor terminal associated with the first SL-PRS. The second indication information is used to notify the anchor terminal to deactivate the first SL-PRS associated with the first area; and / or to notify the anchor terminal to terminate sending the first SL-PRS; and / or to notify the anchor terminal to terminate operation.

[0226] The network device contains at least two predefined or preconfigured zones for a first terminal, and SL-PRS configurations associated with the at least two zones. The network device determines a first zone corresponding to the first terminal based on relevant information about the first terminal, and sends second indication information to an anchor terminal in the first zone. Alternatively, the network device determines a first zone corresponding to the first terminal based on relevant information about the first terminal, determines a first SL-PRS associated with the first zone, determines an anchor terminal associated with the first SL-PRS, and sends second indication information to the anchor terminal associated with the first SL-PRS.

[0227] Optionally, there are at least two areas predefined or preconfigured for the first terminal in the anchor terminal, and SL-PRS configurations associated with at least two areas. In this case, the area identifier of the first area can be carried in the above-mentioned second indication information, and the anchor terminal determines the first SL-PRS associated with the first area based on the area identifier of the first area.

[0228] Optionally, there are no at least two areas predefined or preconfigured for the first terminal, and SL-PRS configurations associated with at least two areas in the anchor terminal. In this case, the SL-PRS configuration of the first SL-PRS may be carried in the above-mentioned second indication information, and the anchor terminal determines the first SL-PRS based on the SL-PRS configuration of the first SL-PRS.

[0229] Optionally, the relevant information of the first terminal may further include at least one of the following: area information of the first area, information of the first SL-PRS.

[0230] Exemplarily, the network device may determine, based on the area identifier of the first area or information about the first SL-PRS, an anchor terminal associated with the first SL-PRS in the first area; for example, based on information about the first SL-PRS, determine the anchor terminal associated with the first SL-PRS, or, based on the area identifier of the first area, determine the first SL-PRS associated with the first area identifier, and then determine the anchor terminal associated with the first SL-PRS. After determining the anchor terminal associated with the first SL-PRS, the network device may send second indication information to the anchor terminal associated with the first SL-PRS.

[0231] Exemplarily, the network device may determine an anchor terminal in the first area based on the area identifier of the first area, and send the second indication information to the anchor terminal in the first area.

[0232] To sum up, in the perception measurement method provided in this embodiment, after the first terminal leaves the first area and enters the second area, it first reports its own location to the network device. After confirming that it has entered the second area, it performs perception measurement through the second SL-PRS associated with the second area, thereby ensuring the accuracy and effectiveness of the SL-PRS measurement.

[0233] Secondly, the method can also enable the anchor terminal to send the second SL-PRS through the network device, thereby supporting the first terminal to quickly switch from measuring the first SL-PRS to measuring the second SL-PRS, thereby reducing the delay of the wireless perception service.

[0234] In the case of requesting the network device to update the SL-PRS configuration associated with the second area, the interaction process between the first terminal and the network device is shown in FIG11 , and the steps are as follows:

[0235] Step 1001: A first terminal sends a message for requesting to update an SL-PRS configuration. The message for requesting to update an SL-PRS configuration is used to request to update an SL-PRS configuration associated with a second area.

[0236] Optionally, the message for requesting to update the SL-PRS configuration includes an SL-PRS configuration update request message. Exemplarily, after entering the second area, the first terminal sends the SL-PRS configuration update request message to request to update the SL-PRS configuration associated with the second area.

[0237] Step 1002: The network device receives a message from a first terminal requesting to update the SL-PRS configuration.

[0238] Exemplarily, the message for requesting to update the SL-PRS configuration is sent by the first terminal after leaving the first area and entering the second area.

[0239] Step 1003: The network device feeds back second confirmation information to the first terminal in response to the message for requesting to update the SL-PRS configuration. The second confirmation information carries update information of the SL-PRS configuration associated with the second area.

[0240] Optionally, the second confirmation information for the message feedback for requesting to update the SL-PRS configuration is carried in the SL-PRS configuration update confirmation message. Exemplarily, the network device sends an SL-PRS configuration update confirmation message to the first terminal in response to the message for requesting to update the SL-PRS configuration, and the SL-PRS configuration update confirmation message carries the second confirmation information.

[0241] Optionally, the update information is used to update part or all of the information in the SL-PRS configuration associated with the second area; and / or the update information is used to be merged into the SL-PRS configuration associated with the second area. That is, the update information is used to update part or all of the information in the SL-PRS configuration associated with the second area; or the update information is used to be merged into the SL-PRS configuration associated with the second area; or the update information includes two parts of information, one part is used to update part or all of the information in the SL-PRS configuration associated with the second area, and the other part is used to be merged into the SL-PRS configuration associated with the second area.

[0242] Step 1004: The first terminal receives second confirmation information for the message feedback requesting to update the SL-PRS configuration.

[0243] Optionally, the first terminal receives an SL-PRS configuration update confirmation message, where the SL-PRS configuration update confirmation message carries the update information. Subsequently, the first terminal obtains the update information from the SL-PRS configuration update confirmation message.

[0244] Step 1005: The first terminal updates the SL-PRS configuration associated with the second area according to the update information.

[0245] The first terminal updates, based on the update information, an existing SL-PRS configuration associated with the second area in the first terminal. Optionally, based on the update information, updates part or all of the information in the SL-PRS configuration associated with the second area; and / or merges the update information into the SL-PRS configuration associated with the second area.

[0246] That is, the first terminal updates some or all of the information in the SL-PRS configuration associated with the second area based on the update information. For example, the predefined or preconfigured SL-PRS configuration includes: an SL-PRS group consisting of at least two SL-PRSs; or an assistance message containing at least two SL-PRSs. The SL-PRS configuration update may be an update of the SL-PRS group or assistance message associated with the second area.

[0247] Alternatively, the first terminal merges the update information into the SL-PRS configuration associated with the second area. For example, the predefined or preconfigured SL-PRS configuration does not include beam indication information (such as beam direction, beam size, etc.); for updating the SL-PRS configuration, the beam indication information in the update information may be merged into the SL-PRS configuration associated with the second area.

[0248] Alternatively, the update information includes two parts of information: a first part of information and a second part of information. The first terminal updates part or all of the information in the SL-PRS configuration associated with the second area according to the first part of information, and merges the second part of information into the SL-PRS configuration associated with the second area.

[0249] For example, the predefined or preconfigured SL-PRS configuration includes: the anchor UE ID associated with the SL-PRS, but does not include: beam indication information; the first part of the information in the update information is the anchor UE ID used for updating, and the second part of the information is the beam indication information used for updating; the SL-PRS configuration associated with the second area is updated based on the anchor UE ID used for updating, and the beam indication information used for updating is merged into the SL-PRS configuration associated with the second area.

[0250] Optionally, the above-mentioned beam indication information is dynamically determined according to the position where the first terminal enters the second area.

[0251] In some other embodiments, the confirmation information may further indicate that the SL-PRS configuration associated with the second area is not updated.

[0252] Step 1006: The first terminal determines a second SL-PRS associated with the second area based on the updated SL-PRS configuration associated with the second area.

[0253] Exemplarily, the first terminal determines the second SL-PRS from the SL-PRS group associated with the second area based on the updated SL-PRS configuration associated with the second area; or determines the second SL-PRS from at least two SL-PRSs included in the auxiliary message associated with the second area.

[0263] Optionally, within the first area, the first SL-PRS associated with the first anchor terminal and the first SL-PRS associated with the second anchor terminal are different.

[0264] Step 1104: The first terminal enters the second area.

[0269] It should be noted that in each embodiment of the present application, the network device is an access network device, such as: gNB; or a core network device, such as: Location Management Function (LMF), Access and Mobility Management Function (AMF), Sensing Control Network Element (SF) any one of them.
