1. A method, comprising:
transmitting to a peer user equipment (UE) assistance information with respect to a result of sensing of one or more resources reserved for a sidelink (SL) communication; and
receiving a transmission from the peer UE on a resource selected by the peer UE based on the assistance information,
wherein the transmitting of the assistance information comprises:
determining a feedback timing, based on a time instant at which the peer UE performs the transmission, to transmit the assistance information; and
updating the assistance information till the assistance information is transmitted at the feedback timing,
wherein the assistance information assists the peer UE in performing in performing selection of one or more of resource, modulation coding scheme (MCS), and demodulation reference signal (DMRS) pattern, thereby improving reliability and reducing latency of SL communications.
