1. A method for operating performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, information on a first threshold value of a channel busy ratio (CBR) and a second threshold value of the CBR;
measuring a first CBR for a serving carrier and a second CBR for at least one candidate carrier;
in case that the first CBR is higher than the first threshold value and the second CBR is lower than the second threshold value, selecting a carrier having a lowest CBR among the at least one candidate carrier;
selecting at least one resource of a resource pool associated with the carrier; and
transmitting data based on the selected at least one resource.
