Title:
METHOD AND DEVICE FOR ACQUIRING INFORMATION RELATED TO CHANNEL CONGESTION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/211510
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication, and a device for supporting same are provided. The method may comprise the steps of: determining a channel busy ratio (CBR) measurement window for measuring a sidelink (SL) CBR; measuring an SL received signal strength indicator (RSSI) for a plurality of sub channels and a plurality of slots within the CBR measurement window; and acquiring a CBR value on the basis of the ratio of the number of sub channels, in which the SL RSSI exceeds a first threshold value, to the number of a plurality of sub channels, the number of a plurality of slots in which the SL RSSI has been measured in the CBR measurement window, and a second threshold value.
