15. A method comprising the following steps performed by a user equipment (UE):
operating a monitoring function that involves monitoring of a downlink control channel of an unlicensed radio cell based on one of a plurality of groups of search space sets, the unlicensed radio cell operating in an unlicensed spectrum and being controlled by a base station that is in communication with the user equipment, wherein one of the plurality of groups of search space sets is configured to be a default group of search space sets,
determining one group of the plurality of search space sets groups for performing the monitoring function, depending on the downlink control channel,
wherein the monitoring function is not performed during a non-monitoring time period, and
determining to perform the monitoring function based on the default group of search space sets, when performing the monitoring function subsequent to the non-monitoring time period.
