1. A method of transmitting a Sidelink Hybrid Automatic Repeat Request (SL HARQ) feedback by a first device, the method comprising:
receiving, from a second device, a Physical Sidelink Control Channel (PSCCH);
receiving, from the second device, a Physical Sidelink Shared Channel (PSSCH) related to the PSCCH;
determining a feedback resource related to transmission of the SL HARQ feedback, among a plurality of feedback resources, based on (i) an identifier (ID) of the first device which is provided to the first device for groupcast communication and (ii) a source ID of the second device; and
transmitting, to the second device, the SL HARQ feedback related to the PSSCH based on the feedback resource.
