RTT BASED SIDELINK RANGING AND POSITIONING

Abstract

A method implemented by first user equipment (UE) include transmitting a first sidelink position reference signal (SL Pos-RS) to a second UE at a first time (t1), receiving a second SL Pos-RS from the second UE at a fourth time (t4), receiving a timing measurement report from the second UE, wherein the timing measurement report contains information regarding a second time (t2) when the first SL Pos-RS was received by the second UE and regarding a third time (t3) when the second UE transmitted the second SL Pos-RS to the first UE, and calculating a distance between the first UE and the second UE based on the first time, the fourth time, and the timing measurement report.
