Document Type and Number:
WIPO Patent Application WO/2021/146986
Kind Code:
A1
Abstract:
Wireless communications systems and methods related to wireless communications in a system are provided. A first wireless communication device may communicate with a second wireless communication device in a listen-before-talk (LBT) bandwidth of a set of LBT bandwidths, downlink control information (DCI). The DCI may indicate acquisition of a channel occupancy time (COT) in a fixed frame period (FFP) across the set of LBT bandwidths and/or a starting point of the FFP in the respective LBT bandwidth. The first wireless communication device may communicate with the second wireless communication device, a communication in at least one LBT bandwidth of the set of LBT bandwidths during the respective COT.
