1. A method of wireless communication performed by a user equipment (UE) operating in a discontinuous reception (DRX) mode, comprising:
receiving a positioning reference signal (PRS) configuration for receiving PRS;
receiving a wake-up signal from a serving base station indicating that the UE is not to wake up during a next ON time during a DRX cycle to monitor for communication signals, the communication signals comprising data signals or control signals or both;
in response to the PRS configuration and the wake-up signal, performing one of:
A) remaining in a DRX sleep mode and not receiving the PRS; or
B) transitioning to a DRX ON mode to receive the PRS but not monitoring for the communication signals; or
C) transitioning to the DRX ON mode to receive the PRS and monitoring for the communication signals.
