Methods, apparatus, and computer-readable media are described to encode, by a first station, duty cycle timing for transmission to a second station via a primary connectivity radio. A wake-up radio (WUR) receiver (WURx) is enabled to receive a transmission based upon the duty cycle timing of the WURx when the primary connectivity radio is in a doze state from a perspective of the second station. A wake-up packet, received from the second station, is decoded and received by the WURx. The WURx receives a WURx transmission when in an WURx awake state. The primary connectivity radio is enabled based upon decoding the wake-up packet.
