Disclosed are techniques for wireless communication. In an aspect, timing of a PRS instance is determined, and timing of a PO is determined based at least in part upon the timing of the PRS instance. UE transitions from DRX OFF state to DRX ON state and receives/measures the PO and PRS resource(s) of the PRS instance (e.g., without returning to DRX OFF state or sleep state until both the PO and PRS resource(s) are received/measured).
