With respect to Claim 1, Shan discloses: a method for determining a ranging/sidelink positioning policy, performed by a policy control function (PCF) network element, the method comprising: determining a ranging/sidelink positioning policy for a user equipment (UE) according to policy-related information (Shan at ¶¶27, 41, 43 and 57 where the AMF sends out Policy Control Function Parameters related to sidelink communications. Also see ¶ 77-81 where this information includes ProSe which is a type of D2D communication which is a sidelink communication) and , wherein the ranging/sidelink positioning policy comprises a parameter required to perform a ranging/sidelink positioning service (¶¶80-91, Note that this limitation has no patentable weight in the method as this information is not used as part of the determination of a policy itself which is the active step in the method); wherein the policy-related information comprises at least one of: capability information received from an access and mobility management function (AMF) network element corresponding to the UE, wherein the capability information indicates that the UE at least supports ranging/sidelink positioning (¶¶80-91, Note that this limitation has no patentable weight in the method as this information is not used as part of the determination of a policy itself which is the active step in the method), or a policy provision request comprised in a UE policy container received from the UE, wherein the policy provision request at least comprises a ranging/sidelink positioning policy provision request for requesting the ranging/sidelink positioning policy. With respect to Claim 2, Shan discloses the method according to claim 1, wherein determining the ranging/sidelink positioning policy for the UE comprises: determining, based on a local policy of the PCF network element or information obtained from a unified data repository (UDR) network element, the parameter and a corresponding parameter value comprised in the ranging/sidelink positioning policy (Shan at ¶30 and 165). With respect to Claim 3, Shan discloses the method method according to claim 1, wherein the ranging/sidelink positioning policy comprises a dedicated parameter for the ranging/sidelink positioning service and a common parameter for both the ranging/sidelink positioning service and at least one of a proximity service (ProSe) and a vehicle to everything (V2X) service (Shan at ¶41 and ¶¶7-87. Note that this limitation is not part of the determining step and thus has no patentable weight.) With respect to Claim `0 , Shan discloses the method method according to claim 1, further comprising: sending the ranging/sidelink positioning policy to the UE through the AMF network element (Shan at ¶155 “AMF 5221 may act as SEAF, which may include interaction with the AUSF 5222 and the UE 5201” and ¶156 “AMF 5221 may also support NAS signaling with a UE 5201 over an N3 IWF interface.”) With respect to Claim 14, Shan discloses a method for determining a ranging/sidelink positioning policy, performed by a user equipment (UE), the method comprising: determining a ranging/sidelink positioning policy sent by an access and mobility management function (AMF) network element corresponding to the UE as the ranging/sidelink positioning policy for the UE (Shan at ¶¶27, 41, 43 and 57 where the AMF sends out Policy Control Function Parameters related to sidelink communications. Also see ¶ 77-81 where this information includes ProSe which is a type of D2D communication which is a sidelink communication. ), wherein the ranging/sidelink positioning policy comprises a parameter required to perform a ranging/sidelink positioning service (¶¶80-91, where various ProSe parameters are listed)). With respect to Claim 15, Shan discloses a method according to claim 14, further comprising: performing the ranging/sidelink positioning service according to the ranging/sidelink positioning policy after receiving a ranging/sidelink positioning service request (Shan at Fig 1, elements 110 and 115).
