TIMING ADJUSTMENT IN SIDELINK

Abstract:

Disclosed are techniques for wireless communication. In an aspect, a receiver user equipment (UE) receives, from a transmitter UE, a sidelink reference signal over a sidelink established with the transmitter UE, and transmits a sidelink timing adjust (TA) command to the transmitter UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE. In an aspect, a transmitter UE transmits, to a receiver UE, a sidelink reference signal over a sidelink established with the receiver UE, and receives a first sidelink TA command from the receiver UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE.
