1. A method of wireless communication at a user equipment (UE), wherein the UE is configured with connected mode discontinuous reception (C-DRX), comprising:
receiving one or more parameters that identify a set of activated secondary cells (SCells) for which the UE is to stop physical downlink control channel (PDCCH) monitoring for a duration of time corresponding to a number of DRX cycles;
stopping the PDCCH monitoring on the set of activated SCells for the duration of time in response to reception of the one or more parameters; and
resuming the PDCCH monitoring on at least one SCell of the set of activated SCells after expiration of the duration of time, wherein the set of activated SCells remain activated during the duration of time.
