1. A first user equipment (UE) in a wireless communication system, the first UE comprising:
a transceiver configured to:
receive first sidelink (SL) control information (SCI), from a second UE, on a physical SL control channel (PSCCH), wherein the first SCI includes first information related to a first SL resource which is a reserved resource, and
receive second SCI, from a third UE, on the PSCCH, wherein the second SCI includes second information related to a second SL resource which is a reserved resource; and
a processor operably coupled to the transceiver, the processor configured to:
identify a conflict on the first SL resource when;
the first UE is an intended recipient of the first SL resource, and RSRP2>RSRP1+a reference signal received power (RSRP) threshold, where RSRP1 is a RSRP of the second UE and RSRP2 is a RSRP of the third UE
wherein the transceiver is further configured to transmit, to the second UE, a physical SL feedback channel (PSFCH) including conflict information when the conflict is identified on the first SL resource, and
wherein first physical resource blocks (PRBs) for the PSFCH including the conflict information are different from second PRBs for another PSFCH including hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback information for a physical SL shared channel (PSSCH).
