Mechanisms To Operate Downlink Wideband Carrier in Unlicensed Band

Abstract:

Systems, devices, and techniques for listen-before-talk (LBT) operations in unlicensed spectrum are described. A described technique includes receiving, by a user equipment (UE), a downlink control information (DCI) message, the DCI message including available bandwidth information and a channel occupancy time (COT) duration, the available bandwidth information being associated with one or more LBT bandwidths of a bandwidth part (BWP) in unlicensed spectrum; receiving, by the UE, one or more physical downlink shared channel (PDSCH) transmissions in the BWP, during the COT duration; and processing the one or more PDSCH transmissions based on the available bandwidth information.
