1. An operating method of a first user equipment (UE) in a wireless communication system, the operating method comprising:
receiving downlink control information (DCI) for sidelink communication from a base station;
transmitting a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) to a second UE, based on the DCI for the sidelink communication;
receiving hybrid automatic repeat and request (HARQ) feedback information through a physical sidelink feedback channel (PSFCH) from the second UE, based on the DCI for the sidelink communication;
in case that a transmission power control (TPC) command field is not included in the DCI for the sidelink communication, determining a TPC command value as a configured value for a physical uplink control channel (PUCCH);
determining transmission power for transmitting the HARQ feedback information to the base station, based on the determined TPC command value; and
transmitting the HARQ feedback information through the PUCCH to the base station, based on the determined transmission power.
