Claim 12:
13. A non-transitory computer-readable medium storing software instructions configured to, when executed by a processor of a wireless communication device, cause the wireless communication device to:
receive, from a base station, a first message granting an uplink transmission at a particular time, the first message including an indication of a listen-before-talk (LBT) category to be used for the uplink transmission;
determine whether the particular time is within a channel occupancy time (COT) initiated by the base station;
in response to determining that the particular time is not within the COT initiated by the base station, perform an LBT procedure defined by the LBT category indicated in the first message;
in response to determining that the particular time is within the COT initiated by the base station, perform an LBT procedure defined by a second LBT category, other than the LBT category indicated in the first message;
in response to successful completion of an LBT procedure, transmit the uplink transmission at the particular time; and
receive, from the base station, a second message indicating timing information for the COT initiated by the base station, wherein determining whether the particular time is within the COT initiated by the base station is based on the timing information.
