1. A method of operating a transmitting user equipment (Tx UE) in a wireless communication system, the method comprising:
receiving, by the Tx UE from a base station, a radio resource control (RRC) configuration message related to a logical channel group, wherein the RRC configuration message includes information informing that Sidelink hybrid automatic repeat request (HARQ) is enabled or disabled; and
transmitting, by the Tx UE to a receiving UE (Rx UE), a message including information on whether the HARQ is enabled or disabled through a Physical Sidelink Shared Channel (PSSCH) based on the RRC configuration message,
wherein, based on that the HARQ is enabled, the Tx UE receives a HARQ feedback from the Rx UE.
