1. A user equipment, comprising:
a receiver, which in operation, monitors, during a first time period, a downlink channel of an unlicensed radio cell for a channel occupancy signal that is transmitted by a base station communicating with the user equipment via the unlicensed radio cell of a mobile communication system, wherein the channel occupancy signal indicates that the base station occupies the downlink channel to perform downlink transmissions;
the receiver, which in operation, receives the channel occupancy signal during the first time period from the base station;
a processor, which in operation, determines that the base station occupies the downlink channel based on the received channel occupancy signal;
after determining that the base station occupies the downlink channel, the receiver, when in operation, monitors, during a second time period, the downlink channel for downlink control information regarding a downlink transmission to be received by the user equipment; and
the receiver, which in operation, receives the downlink control information during the second time period and receives subsequently the downlink transmission from the base station based on the received downlink control information.
