1. A method performed by a wireless device operating in a discontinuous reception (DRX) mode having an active state and a sleep state, the method comprising:
responsive to receiving downlink signaling from a base station indicative of an upcoming data burst during a channel occupancy time, and responsive to the wireless device meeting at least one condition, extending an active time of the DRX mode during which the wireless device is in the active state, wherein the at least one condition comprises:
a condition that is met when the wireless device has a pending data transmission of a service or traffic type associated with the channel occupancy time; or
a condition that is met when the wireless device was unable to be scheduled for data transmission or reception during a last channel occupancy time; or
a condition that is met when a channel access category and/or channel access priority class associated with wireless device data to be transmitted is the same as a channel access category and/or channel access priority class associated with the channel occupancy time.
