1. A method of transmitting a sidelink hybrid automatic repeat request (HARQ) feedback by a user equipment (UE) in a wireless communication system, the method comprising:
generating and configuring an HARQ codebook based on a configuration related to a Uu link;
receiving a physical sidelink feedback channel (PSFCH) from another UE; and
transmitting a sidelink HARQ feedback related to the PSFCH based on the configured HARQ codebook to a base station (BS),
wherein a type of an HARQ codebook for the sidelink HARQ feedback is configured to be the same as a type of an HARQ codebook for a Uu link HARQ feedback.
