1. A method of wireless communication by a user equipment (UE), the method comprising:
receiving signaling indicating a value of a timer for switching to monitoring according to a default group of search space sets;
switching, at a first time period, to monitoring a downlink control channel according to a non-default group of search space sets in an unlicensed spectrum; and
switching, after the first time period, to monitoring the downlink control channel according to the default group of search space sets in the unlicensed spectrum in response to expiration of the timer started based on the switching to monitoring the downlink control channel according to the non-default group of search space sets, wherein the default group of search space sets is configured for monitoring outside of a channel occupancy time (COT) of a serving cell.
