Title:
CHANNEL OCCUPANCY TIME (COT) SHARING IN CASES OF MULTIPLE TRANSMISSION RECEPTION POINTS (mTRP)
Document Type and Number:
WIPO Patent Application WO/2023/060506
Kind Code:
A1
Abstract:
Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.
