Description

[0184] While certain embodiments have been disclosed in detail in this specification, these are for illustrative purposes only and are not intended to limit the scope of the appended claims. In particular, various substitutions, modifications, and changes may be made without departing from the spirit and scope of this disclosure as defined by the claims. Other embodiments, advantages, and changes are to be considered within the scope of the following claims. The presented claims are representative of the embodiments and features disclosed herein. Other unclaimed embodiments and features are also to be considered. Accordingly, other embodiments are within the scope of the following claims. The invention described in the original claims of this application is listed below. [C1] A method for supporting sidelink (SL) positioning performed by a user device (UE), In a message associated with the SL positioning reference signal (PRS), the message includes an indication of the UE as the source of the SL PRS and an SL positioning session identifier. Sending the SL PRS associated with the aforementioned message, Methods that include... [C2] The method according to C1, wherein the message is transmitted using Layer 1 (L1) or Layer 2 (L2) control signaling, or higher layer signaling. [C3] The method according to C2, wherein the L1 control signaling or L2 control signaling includes a sidelink control information (SCI) second stage message or a media access control-control element (MAC-CE) message. [C4] The method according to C1, wherein the instruction for the SL positioning session identifier includes an identifier associated with the SL positioning session. [C5] The method according to C1, wherein the instruction for the SL positioning session identifier includes the expected PRS transmission time of the second UE that initiated the SL positioning session. [C6] The method according to C1, wherein the instruction of the SL positioning session identifier includes a time indicator of when the SL positioning session was started. [C7] The method according to C1, wherein the instruction of the SL positioning session identifier includes an indicator of the carrier frequency on which the SL positioning session was initiated. [C8] The method according to C1, wherein the message further includes the number of UEs involved in the SL positioning session. [C9] Receiving a second message associated with a second SL PRS, wherein the second message includes identification information of a second UE as the source of the second SL PRS and the instruction for the SL positioning session identifier, Receiving the second SL PRS associated with the aforementioned message, To generate the second SL PRS measurement value, Transmitting the measurement value instruction of the second SL PRS, The method according to C1, further comprising the above. [C10] User equipment (UE) configured to support sidelink (SL) positioning, A wireless transceiver configured to communicate wirelessly with a network entity, At least one memory, The system comprises the wireless transceiver and at least one processor coupled to the at least one memory, wherein the at least one processor is In a message associated with an SL positioning reference signal (PRS), the message transmits a message that includes identification information of the UE as the source of the SL PRS and an instruction for an SL positioning session identifier. The SL PRS associated with the message is transmitted. UE is structured in such a way. [C11] The UE described in C10, which transmits the message using Layer 1 (L1) or Layer 2 (L2) control signaling or higher layer signaling. [C12] The UE described in C11, wherein the L1 control signaling or L2 control signaling includes a side link control information (SCI) second stage message or a media access control-control element (MAC-CE) message. [C13] The instruction for the SL positioning session identifier is the UE according to C10, which includes an identifier associated with the SL positioning session. [C14] The UE according to C10, wherein the instruction of the SL positioning session identifier includes the expected PRS transmission time of the second UE that initiated the SL positioning session. [C15] The UE according to C10, wherein the instruction of the SL positioning session identifier includes a time indicator of when the SL positioning session was started. [C16] The UE according to C10, wherein the instruction of the SL positioning session identifier includes an indicator of the carrier frequency on which the SL positioning session was initiated. [C17] The UE according to C10, wherein the message further includes the number of UEs involved in the SL positioning session. [C18] The at least one processor is A second message is received associated with the second SL PRS, the second message includes the identification information of the second UE as the source of the second SL PRS and the instruction for the SL positioning session identifi
