Abstract: 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. After determining that the base station occupies the downlink channel, the UE monitors, during a second time period, the downlink channel for downlink control information regarding a downlink transmission to be received by the user equipment. The UE 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.

Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.
