Title:
METHOD AND APPARATUS OF CHANNEL ACCESS PROCEDURE PRIORITY ON SIDELINK
Document Type and Number:
WIPO Patent Application WO/2023/191563
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 channel access procedure priority on a sidelink (SL) in a wireless communication system. A method of a user equipment (UE) includes determining a type of a SL channel access procedure before a SL transmission, which is a Type 1 SL channel access procedure or a Type 2 SL channel access procedure, and determining, based on a type of the SL transmission, a channel access priority class (CAPC) in case that the type of the SL channel access procedure is the Type 1 SL channel access procedure, wherein the CAPC is associated with a parameter Ρ. The method further includes performing, based on the type of the SL channel access procedure and the CAPC, the SL channel access procedure before the SL transmission and performing the SL transmission if the SL channel access procedure is successfully performed.
