Title:
METHOD AND APPARATUS FOR (RE)SELECTION OF CANDIDATE CARRIERS FOR TRANSMISSION IN SL CA
Document Type and Number:
WIPO Patent Application WO/2023/149750
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for a (re)selection of candidate carriers for transmission in SL CA in a wireless communication system. A method of operating a UE includes: receiving, from a peer UE, an RSRP; identifying information including a first threshold and a second threshold for a sidelink (SL) transmission; determining whether multiple SL carriers are available for the SL transmission; measuring, based on a determination that the multiple SL carriers are available, a CBR; and selecting a SL carrier from the multiple SL carriers for the SL transmission when the measured CBR is less than the first threshold and the received RSRP is greater than the second threshold.
