1. A method of wireless communication at a User Equipment (UE), comprising:
monitoring for a wake-up signal (WUS) from a base station on resources associated with multiple control resource sets (CORESETs), including monitoring for the WUS while performing a discontinuous reception (DRX) cycle, wherein the monitoring includes monitoring for a first WUS in a first CORESET and monitoring for a second WUS in a second CORESET;
receiving, from the base station, the WUS in at least one of the multiple CORESETs during a wake-up signal occasion prior to an on-duration of the DRX cycle; and
transmitting a sounding reference signal (SRS) based on the WUS received in the at least one of the multiple CORESETs, wherein the WUS causes the UE to enter an awake state during the on-duration of the DRX cycle, and the SRS is transmitted during the on-duration of the DRX cycle and in an active bandwidth part (BWP).
