1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a base station, information related to an uplink (UL) resource for reporting sidelink (SL) hybrid automatic repeat request (HARQ) feedback to the base station;
transmitting, to a second device, first sidelink control information (SCI) through a physical sidelink control channel (PSCCH);
transmitting, to the second device, second SCI and a medium access control (MAC) protocol data unit (PDU) through a physical sidelink shared channel (PSSCH) related to the PSCCH;
determining a physical sidelink feedback channel (PSFCH) resource based on an index of a subchannel and an index of a slot related to the PSSCH; and
transmitting, to the base station, the SL HARQ feedback for the MAC PDU based on the UL resource,
wherein a minimum time gap between the PSFCH resource and the UL resource is determined based on N, X, a numerology of a SL bandwidth part (BWP), and a numerology of a UL BWP,
wherein N is determined based on a minimum value among the numerology of the SL BWP and the numerology of the UL BWP, and
wherein X is determined based on information related to a priority.
