Patent number: 11889512Abstract: The present disclosure relates to a user equipment (UE) which monitors, during a first time period, a downlink channel of an unlicensed radio cell for a channel occupancy signal transmitted by a base station via the unlicensed radio cell. The channel occupancy signal indicates that the base station occupies the downlink channel. The UE receives the channel occupancy signal during the first time period from the base station and determines that the base station occupies the downlink channel based on the received channel occupancy signal.
