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.

Abstract: Method and apparatus are provided for estimating first downlink (DL) channel information of first DL channels in accordance with reference signals received on first uplink (UL) channels, the first UL channels being a subset of available UL channels, and the first DL channels corresponding to the first UL channels. Channel feedback is received for a set of DL channels, and second DL channel information is estimated in accordance with the estimated first DL channel information and the received channel feedback.
