1. A method for performing, by a first device, sidelink (SL) communication, the method comprising:
obtaining a set of M physical resource blocks (PRBs) in a resource pool for physical sidelink feedback channel (PSFCH) transmission;
receiving, from a second device, a physical sidelink shared channel (PSSCH) in the resource pool; and
determining a PSFCH resource index of a PSFCH resource, among the M PRBs, for PSFCH transmission in response to the reception of the PSSCH, based on a resource related to the PSSCH,
wherein the PSFCH resource index of the PSFCH resource is determined as a remainder obtained by dividing an index related to the PSFCH resource by a number of available PSFCH resources, and
wherein M is positive integer.
