Optionally, the above-mentioned "QoS requirement category" can include at least one of the following: BestEffort Class, Multiple QoS Class, and Assured Class; optionally, the stringency of the location service quality defined by the "BestEffort Class" is: least stringent; the stringency of the location service quality defined by the "Multiple QoS Class" is: moderately stringent; and the stringency of the location service quality defined by the "Assured Class" is: most stringent. Optionally, the aforementioned “accuracy” can be used to indicate the accuracy requirements during positioning measurement. Optionally, the accuracy can include horizontal accuracy and vertical accuracy during positioning measurement. Optionally, the aforementioned “response time” can be used to indicate the response requirements during positioning measurement. Optionally, the response time can include: no delay, low delay, or delay tolerant.
[0353] Step 2: Terminal 1 discovers that Terminal 2 has reached Terminal n.
[0354] Step 3: Establish secure multicast and / or unicast SL links between any terminals from terminal 1 to terminal n.
[0355] Optionally, terminal 1 can exchange ranging and sidelink positioning protocol (RSPP) messages with any of terminals 2 to n; any terminals between terminals 2 to n can also exchange RSPP messages through the established SL link.
[0356] Step 4: Verify ranging or SL positioning between terminal 1 and any of terminals from terminal 2 to terminal n.
[0357] Optionally, terminal 1 may receive at least one of the following sent by any of terminals 2 to n through the SL link established in step 3: ranging or SL location service authorization, location service policy, location service parameters, and QoS requirements. Terminal 1 may verify whether terminals 2 to n support ranging or SL location service based on at least one of the following sent by terminals 2 to n: ranging or SL location service authorization, location service policy, and location service parameters, and verify whether the QoS requirements of terminals 2 to n match the QoS requirements of terminal 1 based on the QoS requirements sent by terminals 2 to n.
[0358] Step 5: Terminal 1 obtains the positioning capability from Terminal 2 to Terminal n.
[0359] Optionally, terminal 1 can receive the positioning capability of terminal 2 to terminal n through the SL link established in step 3.
[0360] Step 6: Terminal 1 confirms the initiation of SL-MO-LR.
[0361] Optionally, terminal 1 may determine to initiate SL-MO-LR based on the information received in step 4 and the positioning capability received in step 5. Optionally, when the information in step 4 indicates that at least one of terminals 2 to n supports ranging or sidelink positioning services, and the QoS requirements match the QoS requirements of terminal 1, and at least one of terminals 2 to n also has positioning capability, then terminal 1 determines to initiate SL-MO-LR to the AMF, and the SL-MO-LR is used to determine the positioning measurement results of terminal 1.
[0362] Step 7: If terminal 1 is in the Connection Management-IDLE (CM-IDLE) state, terminal 1 triggers a service request in order to establish a connection with AMF.
[0363] Step 8: Terminal 1 sends an SL-MO-LR request to AMF in an uplink non-access stratum (UL NASTRANSPORT) message.
[0364] Alternatively, the SL-MO-LR request may indicate at least one of the following:
[0365] The identifiers of terminals 2 to n may optionally be, for example, at least one of application layer ID and Generic Public Subscription Identifier (GPSI);
[0366] Auxiliary data required for positioning measurements;
[0367] Is LMF needed to assist in positioning calculations?
[0368] Is it necessary to provide the positioning measurement results to at least one of the LCS client, AF, and GMLC?
[0369] The identifier of at least one of LCS client, AF, and GMLC;
[0370] The type of the desired positioning measurement result; optionally, the type of the positioning measurement result may include, for example, the absolute position of terminal 1, the relative position of terminal 1 with any of terminals 2 to n, the distance between terminal 1 and any of terminals 2 to n, and the relative direction between terminal 1 and any of terminals 2 to n.
[0371] QoS requirements.
[0372] Step 9: The AMF selects the LMF and sends an Nlmf_Location_determineLocation request to the LMF based on the SL-MO-LR request.
[0373] Optionally, the content indicated by the Nlmf_Location_determine Location request sent by the AMF to the LMF includes the content indicated by the SL-MO-LR request in step 8 above.
[0374] Step 10: The LMF requests location capabilities from terminals 1 to n.
[0375] Step 11: Terminals 1 to n return their positioning capabilities to the LMF.
[0376] Optionally, terminal 1 and terminal n can return their respective positioning capabilities to the LMF, or terminal 2 to terminal n do not need to send their positioning capabilities to the LMF, but terminal 1 can return the positioning capabilities of terminal 2 to terminal n obtained in step 5 and its own positioning capabilities to the LMF.
[0377] Step 12: Terminal 1 requests auxiliary data required for positioning measurement from LMF.
[0378] Optionally, this auxiliary data can help terminal 1 obtain positioning measurement results.
[0379] Step 13: LMF sends the requested auxiliary data to terminal 1.
[0380] Optionally, the positioning capabilities of terminals 1 to n can also be included in the SL-MO-LR request in step 8. If terminal 1 includes the positioning capabilities of terminals 1 to n in the SL-MO-LR request in step 8, steps 10 and 11 can be omitted. If terminal 1 includes auxiliary data required for positioning measurements in the SL-MO-LR request in step 8, step 12 can be omitted.
[0381] Step 14: If the SL-MO-LR request in Step 8 indicates that the LMF needs to provide location calculation assistance and / or indicates that the location measurement results need to be provided to at least one of the LCS client, AF, and GMLC, then the LMF sends a location information request to terminal 1 through terminal n.
[0382] Step 15: Perform lateral link positioning or ranging between terminal 1 and terminal n to obtain measurement data.
[0383] Step 16: If the absolute position of any terminal from terminal 2 to terminal n is unavailable, the terminal can execute the 5GC-MO-LR procedure to obtain its absolute position.
[0384] Optionally, since the absolute positions of terminals 2 to n are required when calculating the positioning measurement results of terminal 1, when the absolute position of any terminal from terminal 2 to terminal n is unavailable (for example, it can be understood that terminal 2 to terminal n currently does not store its own absolute position), the terminal needs to execute the 5GC-MO-LR process to obtain its absolute position.
[0385] Step 17: If the SL-MO-LR request in step 8 indicates that LMF does not need to provide positioning calculation assistance, or if the calculation subject determined for calculating the positioning measurement result is terminal 1, then terminal 1 calculates the positioning measurement result of terminal 1 based on the measurement parameters obtained in step 15.
[0386] Optionally, in some embodiments, if terminal 1 does not request auxiliary data from LMF in the aforementioned steps, terminal 1 can directly calculate the positioning measurement result based on the measurement parameters obtained in step 15; if terminal 1 requests auxiliary data from LMF in the aforementioned steps, terminal 1 can calculate the positioning measurement result based on the measurement parameters obtained in step 15 and the auxiliary data obtained in step 13.
[0387] Step 18: If terminal 1 receives the location information request sent in step 14 above, terminal 1 sends measurement parameters or measurement results to LMF.
[0388] Optionally, when terminal 1 receives the location information request sent in step 14 above, it indicates that the SL-MO-LR request in step 8 indicates that the LMF needs to provide positioning calculation assistance and / or indicates that the positioning measurement result needs to be provided to at least one of the LCS client, AF, and GMLC. In this case, if the SL-MO-LR request in step 8 indicates that the LMF needs to provide positioning calculation assistance, then in step 18, terminal 1 can send the measurement parameters obtained in step 15 to the LMF so that the LMF can calculate the positioning measurement result of terminal 1 based on the measurement parameters; if the SL-MO-LR request in step 8 indicates that the LMF does not need to provide positioning calculation assistance, and indicates that the positioning measurement result needs to be provided to at least one of the LCS client, AF, and GMLC, then in step 18, terminal 1 can send the positioning measurement result calculated in step 17 to the LMF so that the LMF can send the positioning measurement result to at least one of the LCS client, AF, and GMLC.
[0389] Step 19: LMF calculates the positioning measurement results.
[0390] Optionally, if the LMF receives the measurement parameters sent by the terminal, it indicates that the SL-MO-LR request in step 8 requires the LMF to provide positioning calculation assistance (that is, it indicates that the calculation entity used to calculate the positioning measurement results is the LMF). In this case, the LMF can calculate the positioning measurement results of terminal 1 based on the measurement parameters. Optionally, the type of the positioning measurement results calculated by the LMF should be the type expected by the terminal as indicated by the SL-MO-LR request in step 8 above.
[0391] Step 20: The LMF returns an Nlmf_Location_determine Location response to the AFM, which includes the location measurement results calculated in step 19.
[0392] Step 21: AMF sends the positioning measurement results to at least one of the following: LCS client, AF, and GMLC.
[0393] Optionally, if the SL-MO-LR request in step 8 indicates that the positioning measurement results need to be provided to at least one of the LCS client, AF, and GMLC, then the AMF will send the positioning measurement results to at least one of the LCS client, AF, and GMLC.
[0394] Step 22: The LMF sends an SL-MO-LR response to Terminal 1 in a downlink non-access stratum (DL NASTRANSPORT) message, which includes the positioning measurement results.
[0395] Optionally, if the LMF performs step 19 above, the LMF sends the positioning measurement result calculated in step 19 to terminal 1.
[0396] As described above, the target terminal being located (i.e., terminal 1) can request location assistance from the core network equipment (i.e., AMF and LMF) to determine the location measurement result by executing steps 1-22. However, in a communication system, the target terminal may not be covered by network signals or may not have a NAS connection, resulting in the target terminal being unable to communicate with the core network equipment. In this case, the target terminal needs to select a terminal x from the location terminals (i.e., terminals 2-n) and instruct terminal x to initiate SL-MO-LR on behalf of terminal 1 to achieve the location measurement of terminal 1. Optionally, Figure 1C This is a flowchart illustrating the interaction of a positioning method provided in an embodiment of the present disclosure. Optionally, Figure 1C The method described assumes that the terminal to be located and measured cannot communicate with core network equipment (such as AMF). Figure 1C As shown, the positioning method may include:
[0397] Step 1: Terminal 1 executes the above... Figure 1B Steps 1-5 in the process.
[0398] Step 2: Terminal 1 selects a terminal x from the positioning terminals (i.e., terminals 2-n mentioned above) and sends an SL positioning information request to terminal x.
[0399] Optionally, the SL location information request may include at least one of the following:
[0400] The identifier of the LMF stored in terminal 1;
[0401] QoS requirements;
[0402] The identifier of terminal 1.
[0403] Step 3: Terminal x executes the above steps. Figure 1BStep 6-22 in the process is to obtain the positioning measurement results of terminal 1.
[0404] Step 4: Terminal x sends an SL positioning information response, including the positioning measurement results of terminal 1, to the target UE.
[0405] but, Figure 1C The following issues remain unresolved in the method shown.
[0406] First, how can terminal 1 select terminal x from among terminals 2 to n?
[0407] Second, what protocol do Terminal 1, Terminal x, AMF, and LMF use to communicate?
[0408] Third, when terminal x obtains the positioning measurement results of terminal 1, it usually needs to know the absolute positions of terminal 2 to terminal n. How does terminal x obtain the absolute positions of terminal 2 to terminal n?
[0409] Figure 2A This is an interactive schematic diagram illustrating a positioning method according to an embodiment of this disclosure. For example... Figure 2A As shown, this disclosure relates to a positioning method for a communication system 100, the method comprising:
[0410] Step 2101: Some or all of the second terminals send the second information to the first terminal respectively.
[0411] Optionally, in some embodiments, the second terminal can be a terminal discovered by the first terminal; alternatively, in some embodiments, the number of second terminals can be at least one.
[0412] Optionally, in some embodiments, the first terminal can be the target terminal (TargetUE) to be located and measured. Optionally, in some embodiments, the first terminal cannot communicate with the first network element and requires the assistance of the first network element to complete the positioning process of the first terminal. Optionally, in some embodiments, the aforementioned first network element can be used to perform registration, connection, reachability, and mobility management, provide a session management message transmission channel for the device, and provide authentication and authorization functions for terminal access. The first network element can be an access point for the terminal device and the wireless core network control plane. The first network element can be an AMF (Access Provider Function), but the name of the first network element is not limited to this.
[0413] Optionally, in some embodiments, the aforementioned "requiring the assistance of the first network element to complete the positioning process of the first terminal" may include at least one of the following:
[0414] The first network element needs to select the second network element, which is used to send third information for assisting in positioning;
[0415] The first network element needs to select the second network element, which is used to calculate the positioning measurement results of the first terminal;
[0416] The positioning measurement results of the first terminal need to be sent from the first network element to the third network element.
[0417] Optionally, the second network element can be used to manage the links and resources between various network elements in the access network. The second network element may be, for example, an LMF, but the name of the second network element is not limited to this. Optionally, the third network element can be used to provide location-based services. The third network element may be, for example, any of the following: AF, LCS client, GMLC, NEF, but the name of the third network element is not limited to this.

[0424] Optionally, in some embodiments, the network element identifier included in the second information described above can be the network element identifier corresponding to the second network element that the second terminal has communicated with. Optionally, in some embodiments, the second network element can be used to manage the links and resources between various network elements in the access network. The second network element can be, for example, an LMF, and the name of the second network element is not limited to this.
[0425] Step 2102: The first terminal determines that it wants to initiate the first process.
[0426] Optionally, the first procedure can be used to determine the positioning measurement results of the first terminal. Optionally, the first procedure can be SL-MO-LR, and the name of the first procedure is not limited to this.
[0427] Optionally, in some embodiments, in response to the existence of a second terminal in at least one second terminal that can communicate with the first network element, the first terminal determines to initiate the first process.
[0428] Step 2103: The first terminal selects a third terminal from at least one second terminal.
[0429] Optionally, in some embodiments, the first terminal may select a third terminal from at least one second terminal that has sent the second information described above.
[0430] Optionally, the aforementioned third terminal can be used to initiate a first procedure to the first network element in place of the first terminal to achieve positioning measurement of the first terminal. Optionally, as can be seen from the foregoing, the positioning process of the first terminal requires the assistance of the first network element. However, since the first terminal cannot communicate with the first network element, it cannot initiate a first procedure to determine the positioning measurement result of the first terminal. In this case, the first terminal needs to select a third terminal from at least one second terminal so that the third terminal can initiate a first procedure to the first network element in place of the first terminal to achieve positioning measurement of the first terminal.
[0431] Optionally, in some embodiments, the method for selecting a third terminal from at least one second terminal described above may include at least one of the following:
[0432] Select at least one of the second terminals that can communicate with the first network element as the third terminal;
[0433] The second terminal whose network element identifier included in the second information is the same as the network element identifier of the second network element stored in the first terminal is identified as the third terminal.
[0434] For example, in some embodiments, the first terminal may select a terminal among the second terminals that can communicate with the first network element as the third terminal; or, in some embodiments, the first terminal may determine a second terminal whose network element identifier included in the second information sent is the same as the network element identifier of the second network element stored in the first terminal as the third terminal; or, in some embodiments, the first terminal may determine a second terminal among the second terminals that can communicate with the first network element and whose network element identifier included in the second information sent is the same as the network element identifier of the second network element stored in the first terminal as the third terminal; or, in some embodiments, the first terminal may determine a second terminal among the second terminals that can communicate with the first network element and whose network element identifier included in the second information sent is the same as the network element identifier of the second network element stored in the first terminal as the third terminal.
[0435] Optionally, in some embodiments, the network element identifier of the second network element stored in the first terminal can be understood as, for example, the network element identifier of the second network element that the first terminal has communicated with.
[0436] Step 2104: The first terminal selects at least one fourth terminal from at least one second terminal.
[0437] Optionally, in some embodiments, the fourth terminal can be a location terminal (Located UE), which can satisfy at least one of the following conditions: it can communicate with the first network element, and its absolute position is known. Optionally, "the fourth terminal can communicate with the first network element" means that the fourth terminal can obtain its absolute position by requesting the first network element; "the fourth terminal knows its own absolute position" means that the fourth terminal has stored its own absolute position. Optionally, when the fourth terminal satisfies the above conditions, it means that the fourth terminal can know its own absolute position. At this time, the fourth terminal can act as a location terminal to realize the positioning measurement of the first terminal. Optionally, the process of the fourth terminal realizing the positioning measurement of the first terminal can be as follows: the first terminal and the fourth terminal can send positioning reference signals to each other, and the first terminal and the fourth terminal can respectively measure and analyze the positioning reference signals they receive to determine at least one of the relative position, relative angle, and relative distance between the first terminal and the fourth terminal. Then, combined with the absolute position of the fourth terminal, the positioning measurement of the first terminal can be realized.
[0438] Optionally, it should be noted that in some embodiments, the third terminal selected by the first terminal may be included among at least one fourth terminal; that is, the third terminal can be any fourth terminal. In this case, the third terminal serves as both the positioning terminal and the terminal that initiates the first process on behalf of the first terminal. In other embodiments, the third terminal selected by the first terminal may not be a fourth terminal. In this case, the third terminal serves as the terminal that initiates the first process on behalf of the first terminal, and does not serve as the positioning terminal.
[0439] Step 2105: The first terminal sends the first information to the third terminal.
[0440] Optionally, the first information can be used to request the third terminal to initiate a first process to the first network element.

[0456] Optionally, the "calculation subject for calculating the positioning measurement result of the first terminal" can be determined by any one of the first terminal, the third terminal, and the second network element. Optionally, it is generally determined by the second network element by default. However, it is also possible that the calculation subject for the positioning measurement result of the first terminal or the third terminal can be determined. Optionally, when the first terminal determines the calculation subject for the positioning measurement result of the first terminal, the third terminal and the second network element shall follow the determination result of the first terminal. When the first terminal does not determine the calculation subject for the positioning measurement result of the first terminal, but the calculation subject for the positioning measurement result of the first terminal is determined by the third terminal, the first terminal and the second network element shall follow the determination result of the third terminal. Optionally, in some embodiments, when the first information includes the above-mentioned fourth instruction, it indicates that the first terminal has determined the calculation subject for the positioning measurement result of the first terminal. At this time, the third terminal and the second network element shall follow the determination result of the first terminal (i.e., follow the instruction of the fourth instruction). When the first information does not include the above-mentioned fourth instruction, it indicates that the first terminal has not determined the calculation subject for the positioning measurement result of the first terminal. At this time, the calculation subject for the positioning measurement result of the first terminal may be determined by the third terminal or the second network element.
[0457] Optionally, in some embodiments, the network element identifier indicated in the seventh instruction above may be the network element identifier of a third network element that needs to be sent the positioning measurement results of the first terminal and the absolute position of the fourth terminal.
[0458] Optionally, in some embodiments, the type of the above-mentioned positioning measurement result may include at least one of the following: the absolute position of the first terminal, the relative position of the first terminal and the fourth terminal, the distance between the first terminal and the fourth terminal, and the relative direction between the first terminal and the fourth terminal.
[0459] Step 2106: The third terminal determines that it wants to initiate the first process.
[0460] Optionally, in some embodiments, when the third terminal receives the first information sent by the first terminal, the third terminal determines to initiate the first process.
[0461] Optionally, in some embodiments, steps 2102 and 2106 can be performed in one of them. For example, only step 2102 or only step 2106 can be performed; alternatively, in other embodiments, both steps 2102 and 2106 can be performed.

[0481] Optionally, in some embodiments, the fourth indication in the second request may be the fourth indication included in the first information received by the third terminal from the first terminal. In this case, it is considered that the calculation subject for calculating the positioning measurement result of the first terminal was determined by the first terminal. Alternatively, in some embodiments, the fourth indication may be determined by the second terminal when the first information sent by the first terminal does not include the fourth indication. In this case, it is considered that the first terminal did not determine the calculation subject for calculating the positioning measurement result of the first terminal, but the second terminal determined the calculation subject for calculating the positioning measurement result of the first terminal. Or, in yet other embodiments, the second request may not carry the fourth indication, and the first information may not carry the fourth indication.

[0502] Step 2110: The third terminal sends the third information to the first terminal.
[0503] Step 2111: The first terminal obtains measurement data by communicating with at least one fourth terminal to perform positioning measurements.
[0504] Optionally, in some embodiments, the method by which the first terminal obtains measurement data by communicating with at least one fourth terminal to perform positioning measurement may include: the first terminal may send a positioning reference signal to the fourth terminal, and after receiving the positioning reference signal, the fourth terminal obtains measurement data by measuring the positioning reference signal and sends the measurement data to the first terminal; or, the fourth terminal sends a positioning reference signal to the first terminal, and after receiving the positioning reference signals sent by each of the fourth terminals, the first terminal obtains measurement data by measuring the positioning reference signal.
[0505] Step 2112: The first terminal calculates the positioning measurement result of the first terminal based on at least one of the measurement data, the absolute position of the fourth terminal, and the third information.
[0506] Step 2113: The second network element sends a third request to the third terminal.
[0507] Optionally, in some embodiments, the third request is used to request at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal.
[0508] Optionally, in some embodiments, when it is necessary to send at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element, the second terminal may send a third request to the third terminal.

[0513] Optionally, in some embodiments, the first terminal sends its positioning measurement results to the third terminal so that the third terminal can subsequently send them to the third network element.
[0514] Optionally, it should be noted that, as can be seen from the content of step 2105 above, the first information sent by the first terminal to the third terminal may indicate whether it is necessary to send at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element. Based on this, the first terminal may know whether it is necessary to send at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element without the first request. Therefore, step 2114 can be an optional step, which can be executed or not.
[0515] Similarly, as can be seen from the content of step 2107 above, the third terminal sending a second request to the first network element may also indicate whether it is necessary to send at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element. Based on this, the third terminal may know whether it is necessary to send at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element without a third request. Therefore, step 2113 can be an optional step, which can be executed or not.
[0516] Step 2116: The third terminal sends at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to at least one of the first network element and the second network element.
[0517] Optionally, in some embodiments, when it is necessary to send the positioning measurement result of the first terminal to the third network element, the third terminal, after receiving the positioning measurement result sent by the first terminal, can send the positioning measurement result to at least one of the first network element and the second network element, so that at least one of the first network element and the second network element can subsequently send it to the third network element.
[0518] Step 2117: At least one of the first network element and the second network element sends at least one of the positioning measurement results of the first terminal and the absolute position of the fourth terminal to the third network element.
[0519] Optionally, in some embodiments, the third terminal may send at least one of the positioning measurement results and the absolute location of the fourth terminal to the second network element. Then, the second network element directly sends at least one of the positioning measurement results and the absolute location of the fourth terminal to the third network element. Alternatively, the second network element may send at least one of the positioning measurement results and the absolute location of the fourth terminal to the first network element, and then the first network element sends at least one of the positioning measurement results and the absolute location of the fourth terminal to the third network element. Optionally, the second network element may send a third message including the positioning measurement results. The first network element may receive the third message, which may be, for example, an Nlmf_Location_DetermineLocation response message, but is not limited to this; it may also be other messages used to respond to location requests.

[1033] Figure 8B This is a schematic diagram of the interaction flow of the positioning method according to an embodiment of this disclosure. Figure 8B As shown, the above method includes at least one of the following:
[1034] 1-5. The target UE executes steps 1-5 of the SL-MO-LR procedure in TS 23.273 (i.e., the aforementioned...). Figure 1BSteps 1-5 in the above steps should be modified as follows:
[1035] -UE1 (i.e. the aforementioned first terminal) is a target UE that cannot establish a NAS connection or cannot be served by an LMF with ranging / SL positioning capabilities, and UE2 / ... / UEn is a positioning UE or an SL reference UE, whereby at least one of UE2 / ... / UEn is within the coverage area and can be served by an LMF with ranging / SL positioning capabilities.
[1036] Step 5: UE1 acquires the capability of UE2 to UEn (UE2 to UEn is the aforementioned fourth terminal) and the network connection status of UE2 to UEn. For example, UE2 has a NAS connection, while UE3 does not. For the UE being located that does not have a NAS connection, if the absolute location of the UE being located is known, the UE being located also sends an indication of its absolute location or that its absolute location is known to the target UE.
[1037] Scenario a: UE1 decides to execute SL-MO-LR and selects UE2 (i.e., the aforementioned third terminal) to initiate SL-MO-LR on its behalf.
[1038] 6. Based on UE1's sidelink positioning capability and the information received in steps 4 and 5, if at least one of the discovered UE2 / ... / UEn is within network coverage and can be served by an LMF with ranging / SL positioning capability, then UE1 determines that SL-MO-LR will be performed. UE1 also selects the UE to be located to perform ranging. At least one of the selected UEs to be located should have a NAS connection; if the UE to be located does not have a NAS connection, then the target UE selects only the UE to be located with a known absolute location.
[1039] 7. UE1 also selects one of UE2 / ... / UEn to initiate SL-MO-LR on its behalf, based on information obtained in previous steps, including capabilities and network connectivity status. For example, UE1 selects UE2, which is within network coverage and can be served by an LMF with ranging / SL positioning capabilities.
[1040] 8. UE1 sends an SL location information request to the next selected UE2, requesting its absolute location. This request may include a routing identifier, QoS requirements, the target UE ID (e.g., GPSI), and UE1's ability to connect to UEn and its network connectivity status (UE2's information may not be required). It may also indicate any necessary auxiliary data, whether location calculation assistance is needed, and whether the location results should be transmitted to the LCS client or AF.
[1041] Scenario b: UE1 has transmission capability, UE2 decides to execute SL-MO-LR
[1042] 6. Based on the information obtained in the previous steps, including capability and network connectivity status, UE1 selects one of UE2 / ... / UEn (e.g., UE2) that has a NAS connection. For example, UE1 selects UE2, which is within network coverage and can be served by an LMF with ranging / SL positioning capabilities. UE1 also selects the located UE to perform ranging. At least one of the selected located UEs should have a NAS connection; if a located UE does not have a NAS connection, the target UE selects only the located UE with a known absolute location.
[1043] 7. UE1 sends an SL location information request to the next selected UE2, requesting its absolute location. This request may include a route identifier, QoS requirements, target UE ID (e.g., GPSI), and UE1's ability to reach UEn and its network connectivity status (UE2's information may not be required).
[1044] 8. Based on the sidelink positioning capability and network connection status from UE1 to UEn, UE2 determines that it needs to perform SL-MO-LR.
[1045] 9-26. UE2 performs step 7-15 of the SL-MO-LR procedure on behalf of UE1, with the following adaptations:
[1046] - Step 9: If UE2 is in CM-IDLE state, UE2 initiates a UE-triggered service request in order to establish a signaling connection with UE2's service AMF.
[1047] Step 10: UE2 sends a Supplemental Service SL-MO-LR Request to the Serving AMF in the UL NAS Transmission Message. The SL-MO-LR Request indicates to other UEs 1 through UEn (using application layer IDs, such as GPSI), possibly indicating the capabilities and network connectivity status of UEs 1 through UEn, indicating any necessary auxiliary data, indicating whether location calculation assistance is required, and indicating whether the location results should be transmitted to the LCS client or AF. For the transfer to the LCS client or AF, details of the LCS client or AF (and possibly GMLC) and the application layer IDs of all UEs are also included. For location calculation assistance from the LMF, the preferred type of sidelink positioning / ranging location results (e.g., absolute location, relative location, or distance and orientation between UE pairs) and the required QoS are included.
[1048] - Step 11: The serving AMF selects the LMF serving UE2 (e.g., an LMF that supports sidelink positioning / ranging) and sends the Nlmf_Location_determineLocation service operation to the LMF using the information from the SL-MO-LR request.
[1049] - Step 12: LMF sends a request to UE2 for the capabilities of all UE1 to UEn.
[1050] - Step 13: If not all UEs have NAS connections, UE2 returns the capability from UE1 to UEn to the LMF.
[1051] Note: If the SL-MO-LR request in step 10 includes the capability from UE1 to UEn, steps 12 and 14 can be skipped.
[1052] Step 14: UE2 can send a request for specific auxiliary data to LMF.
[1053] Step 15: The LMF sends the requested auxiliary data to UE2. The auxiliary data can help UE1 to n obtain lateral link position measurement results, and / or can help UE1 or UE2 calculate lateral link positioning / ranging position results.
[1054] Note 1: If UE2 includes a message containing the capabilities of ue1 to n in the SL-MO-LR request in step 10, steps 12 and 13 can be omitted. If UE2 includes a message containing a request for specific auxiliary data in the SL-MO-LR request in step 10, step 14 can be omitted.
[1055] - Step 16: If the SL-MO-LR request in step 10 indicates a need for location calculation assistance and / or instructs the transmission of sidelink positioning / ranging location results to the LCS client or AF, then the LMF sends a location information request to UE2, which may include location information requests to UE1 or UE1 to n.
[1056] - Step 17: UE2 sends a request to UE1 to perform a sidelink localization / ranging procedure between UE1 and n. If calculations are performed on UE1, this may include auxiliary data (if received in step 15) and requested location information (if received in step 16).
[1057] UE1 initiates a lateral link positioning / ranging process between UE1 and n, where UE1 and n obtain lateral link position measurements, and UE2 and n transmit their lateral link position measurements to UE1.
[1058] - Step 18: If the absolute location information of UE1 is required, and if the absolute locations of UE2...UEn are not available, UE2...UEn with NAS connection can perform the 5GC-MO-LR procedure to obtain their absolute locations.
[1059] Step 19: If UE1 does not decide to request assistance from the LMF, or if the LMF decides to use UE-based calculations, then UE1 calculates its own lateral link positioning / ranging position results, as well as those of UE2 to n, based on the lateral link position measurement from Step 17 and possibly using the assistance data received in Step 15. The lateral link positioning / ranging position results may include absolute position, relative position, or range and orientation related to UE1 to n.
[1060] Step 20:
[1061] If the calculation is not performed on UE1 (it may be on UE2 or LMF), UE1 provides the sidelink positioning / ranging measurements between UE1 and UE2 to UEn, as well as the absolute positions of UE2 to UEn to UE2, if UE2 does not know the absolute position of the positioned UE. (This could be because the absolute position of the positioned UE is only transmitted to UE1, and UE2 does not have this information. Or, not all absolute position information is provided in the auxiliary data in step 14.)
[1062] Alternatively, if calculations are performed on UE1 and UE1 receives a location information request from UE2, and UE2 receives the request in step 16, then UE1 provides UE2 with the results of the sidelink positioning / ranging between UE1 and UE2.
[1063] Step 21: Based on the lateral link position measurement in Step 20, and possibly using the auxiliary data received in Step 15, UE2 calculates its own lateral link positioning / ranging position results and those of each of UE2 to n.
[1064] Step 22: If UE2 receives a request for location information in step 16, UE2 sends a response to LMF, including lateral link location measurements and the absolute location of the located UE without NAS connectivity, or if the result of step 19 is performed.
[1065] - Step 23: If step 22 occurs, and if location calculation assistance from the LMF was requested in step 10, then the LMF calculates the lateral link positioning / ranging location results for UE1 to n. The lateral link positioning / ranging location results may include absolute position, relative position, or range and orientation related to UE1 to n.
[1066] Step 24: The lmf returns the Nlmf_Location_determineLocation service operation response to the AMF, including any sidelink positioning / ranging location results received in step 22 or calculated in step 23.
[1067] - Step 25: If the lateral link positioning / ranging location result is received in step 22, the AMF performs steps 7-12 of section 6.2 to send the lateral link positioning / ranging location result to the GMLC, and, if requested in step 10, to the AF or LCS client. The lateral link positioning / ranging location result includes the global identity of UE1 to n received in step 10.
[1068] Note 2: Sending location results and global identity of UE1 to n to the AF or LCS client may require privacy verification from UE1 to n and / or from the HPLMN of UE1 to n.
[1069] Step 26: If step 23 was performed, the LMF returns a supplemental service SL-MO-LR response to UE1 in a DL NASTRANSPORT message, including any sidelink positioning / ranging location results calculated in step 23.
[1070] Step 27. UE2 sends an SL location information provision message containing the target UE's location to UE1.
[1071] The protocols used for transmission between UE1 and UE2, and between UE2 and LMF, can be RSPP, application layer protocols, PC5-U, or PC5-S.
[1072] In the SL localization process for a target UE without NAS connectivity, it is possible to support the localized UE with a known absolute location that has no NAS connectivity.
[1073] Based on the above, the following three points can be achieved in the embodiments disclosed herein:
[1074] 1. Steps 6-8: The target UE without NAS connection selects the target UE with NAS connection from all the located UEs, and the selected target UE performs SL-MO-LR on behalf of the target UE to support the case where not all the located UEs are located.
[1075] 2. Steps 20 and 22: The selected UE being located sends a lateral link positioning / ranging measurement with the absolute position of the UE being located to the selected UE2 and LMF. The UE being located has no NAS connection or result.
[1076] 3. The protocols used for transmission between UE1 and UE2, and between UE2 and LMF, can be RSPP, application layer protocols, PC5-U, or PC5-S.

The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
