Title:
MULTIPLE STARTING POINTS IN RELATION TO A CHANNEL OCCUPANCY TIME (COT) FOR SIDELINK COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/237515
Kind Code:
A1
Abstract:
Wireless communications systems and methods related to communicating a sidelink communication among sidelink user equipment devices (UEs) are provided. A UE may determine a first starting point from a plurality of starting points and perform a listen-before-talk (LBT) to contend for a channel occupancy time (COT) beginning at the first starting point. The UE may transmit, during the COT based on the LBT, a sidelink communication beginning at the first starting point.
