Abstract
Provided are a method of selecting carriers and a device supporting the method. According to one embodiment of the present invention, a method for selecting carriers in a wireless communication system includes: receiving information on carriers and Channel Busy Ratio threshold from a network; selecting at least one carrier of which CBR value is below the CBR threshold; selecting a resource on the selected carrier; and transmitting a medium access control (MAC) packet data unit (PDU) by using the selected resource of the selected carrier.
Claims11
A method performed by a wireless device operating in a wireless communication system, the method comprising:
- acquiring information regarding multiple carriers and multiple channel busy ratio (CBR) thresholds, wherein each of the multiple CBR thresholds is configured per each of the multiple carriers;
- acquiring a CBR value of each of the multiple carriers;
- determining a number of carriers to be selected;
- selecting at least one candidate carrier among the multiple carriers, where for each of the at least one candidate carrier, the candidate carrier has a CBR value below a CBR threshold which is configured for the candidate carrier;
- based on the number of carriers to be selected being larger than the number of the at least one candidate carrier, selecting at least one additional carrier among the multiple carriers in an increasing order of the CBR value from a lowest CBR value of the at least one additional carrier, where for each of the at least one additional carrier, the additional carrier has a CBR value above a CBR threshold which is configured for the additional carrier;
- selecting a sidelink resource on the selected at least one candidate carrier and the at least one additional carrier;
- and
- transmitting a medium access control (MAC) packet data unit (PDU) based on the sidelink resource.
