1. A user equipment (UE), comprising:
processor circuitry configured to:
acquire a channel occupancy time (COT) in an unlicensed spectrum;
determine the UE is a configured grant UE and further determine a number of consecutive subframes allocated for a physical uplink shared channel (PUSCH) transmission to a base station according to a time domain configuration for the configured grant UE;
determine a number of remaining consecutive subframes of the number of consecutive subframes allocated for the PUSCH transmission to the base station; and
generate uplink control information (UCI) to indicate a COT sharing boundary, the COT sharing boundary occurring at an end of the remaining consecutive subframes, the UCI further indicating a slot for monitoring for physical downlink control channel (PDCCH) transmission; and
radio front end circuitry, coupled to the processor circuitry, configured to:
transmit the UCI in the PUSCH transmission during one of the remaining consecutive subframes, wherein the PUSCH transmission and the UCI are transmitted in a same slot; and
the processor circuitry is further configured to:
monitor downlink transmissions from the base station following the COT sharing boundary.
