1. A method of a first User Equipment (UE) for transmitting a Physical Sidelink Feedback Channel (PSFCH) in a wireless communication system, the method comprising:
receiving, from a second UE, a first Physical Sidelink Control Channel (PSCCH), wherein a first Sidelink Control Information (SCI) related to the first PSCCH is for scheduling of a first Physical Sidelink Shared Channel (PSSCH);
receiving, from the second UE, the first PSSCH;
receiving, from the second UE, a second PSCCH, wherein a second SCI related to the second PSCCH is for scheduling of a second PSSCH;
transmitting, to the second UE, a first PSFCH providing HARQ-ACK information related to the reception of the first PSSCH; and
transmitting, to the second UE, a second PSFCH providing conflict information related to a reception of the second PSSCH;
wherein the second PSFCH is transmitted in a slot that is at least T3 slots before a slot of a reserved resource based on the second SCI,
wherein the T3 is equal to Tproc,1SL determined based on a SubCarrier Spacing (SCS) configuration of a SideLink BandWidth Part (SL BWP), and
wherein the first PSFCH and the second PSFCH are transmitted in different Physical Resource Blocks (PRBs).
