1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a base station, configuration information related to a plurality of logical channels;
determining one or more logical channels of interest from among the plurality of logical channels;
based on sidelink (SL) hybrid automatic repeat request (HARQ) feedback being enabled for at least one logical channel among the one or more logical channels of interest, allocating N SL processes, from among a plurality of SL processes for transmitting a plurality of medium access control protocol data units (MAC PDUs), to a SL resource in which a physical sidelink feedback channel (PSFCH) resource is configured; and
performing HARQ feedback-based SL communication based on the N SL processes,
wherein N is a positive integer, and
wherein the one or more logical channels of interest include a logical channel in which data is not available at a first time and available data is expected to occur at a second time.
