1. A method for performing, by a first device (100), sidelink communication, the method comprising:
obtaining configuration information related to multiple bandwidth parts (BWPs) included in a first carrier;
obtaining configuration information related to multiple BWPs included in a second carrier;
performing a first channel busy ratio (CBR) measurement for one or more BWPs related to a first sidelink service, among the multiple BWPs included in the first carrier;
determining a CBR value of the first carrier, based on first CBR measurement values for one or more BWPs related to the first sidelink service, among the multiple BWPs included in the first carrier;
performing a second CBR measurement for one or more BWPs related to the first sidelink service, among the multiple BWPs included in the second carrier;
determining a CBR value of the second carrier, based on second CBR measurement values for one or more BWPs related to the first sidelink service, among the multiple BWPs included in the second carrier; and
selecting the first carrier, based on the CBR value of the first carrier and the CBR value of the second carrier,
wherein the CBR value of the first carrier and the CBR value of the second carrier are equal to or less than a CBR threshold value related to the first sidelink service, and
wherein the CBR value of the first carrier is smaller than the CBR value of the second carrier.
