1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a first channel busy ratio (CBR) threshold, a second CBR threshold, and information on a sidelink channel priority associated with the first CBR threshold and the second CBR threshold;
identifying a first CBR for a serving carrier and a second CBR for at least one candidate carrier;
selecting a carrier having a lowest CBR among the at least one candidate carrier, in case that the first CBR is higher than the first CBR threshold associated with the sidelink channel priority and the second CBR is lower than the second CBR threshold associated with the sidelink channel priority; and
selecting at least one resource of a resource pool associated with the carrier.
