Title:
METHOD AND APPARATUS FOR SUPPORTING DISCOVERY BURST FOR SIDELINK
Document Type and Number:
WIPO Patent Application WO/2023/182809
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The methods and apparatuses for discovery burst transmission for a sidelink (SL) in a wireless communication system. A method of a user equipment (UE) includes identifying a set of sidelink (SL) synchronization signals and physical SL broadcast channel (S-SS/PSBCH) blocks for a SL discovery burst, determining a transmission duration of the SL discovery burst, and determining a duty cycle of the SL discovery burst. The method further includes determining, based on the transmission duration and the duty cycle, a type of SL channel access procedure; performing, based on the type of SL channel access procedure, a SL channel access procedure; and transmitting the SL discovery burst after successfully performing the SL channel access procedure.
