1. A method performed by a user equipment (UE), the method comprising:
identifying information for a resource pool;
identifying a resource allocation mode;
identifying physical sidelink feedback channel (PSFCH) information, wherein the PSFCH information includes information for a PSFCH period; and
performing a resource selection for transmission, by the UE, based on the information for the PSFCH period, a time required for PSFCH reception and decoding, and a time for retransmission preparation, in case that the resource allocation mode is resource allocation mode 2, and
wherein a time interval associated with the resource selection for transmission is defined as [n+T1, n+T2], where the TI is associated with a processing time for selection of a resource for transmission, and the T2 is associated with a packet delay budget.
