Abstract: Systems and methods for activation and deactivation of Sidelink (SL) Positioning Reference Signal (PRS) are provided. In some embodiments, a method performed by a UE includes: receiving control signaling for triggering SL PRS, where the control signaling includes: a resource allocation in time and/or frequency domain; a comb and/or repetition factor associated with SL PRS; an identifier for the SL PRS; an offset between receiving the control signal and when the SL PRS will be transmitted or received/measured; and an indicator indicating whether the SL PRS is for transmission or reception/measurement by the UE. In this way, some embodiments enable semi-persistent or aperiodic SL PRSs to be activated/deactivated or triggered on when SL positioning measurements are needed. Hence, these embodiments allow interference caused by SL PRS to other UEs to be reduced. In addition, the proposed solutions also reduce the SL overhead when compared to a periodic SL PRS transmission.
