Sidelink positioning for multiple target user equipment

A method of performing operations, comprising:

• transmitting, by a reference UE, a first SL positioning reference signal (SL-PRS) to a first target UE and a second target UE;
• receiving, by the reference UE and in response to transmitting the first SL-PRS, a second SL-PRS and a third SL-PRS from the first target UE and the second target UE, respectively;
• and
• obtaining, by the reference UE, (i) first time of flight (ToF) information indicative of a first distance between the reference UE and the first target UE based on the second SL-PRS, and (ii) second ToF information indicative of a second distance between the reference UE and the second target UE based on the third SL-PRS.

One or more processors of a user equipment (UE) configured to, when executing instructions stored in a memory, perform operations for sidelink (SL) positioning of a plurality of UEs in a single positioning session, the operations comprising:

• receiving, by the UE, a first SL positioning reference signal (SL-PRS) from a first UE of the plurality of UEs;
• transmitting, by the UE and in response to the received first SL-PRS, a second SL-PRS to the first UE;
• receiving, by the UE and in response to transmitting the second SL-PRS, a third SL-PRS from the first UE;
• and
• obtaining, by the UE, time of flight (ToF) information indicative of a distance between the UE and the first UE based on at least one of the second SL-PRS or the third SL-PRS.
