Abstract
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.

(canceled)
An apparatus of a non-access point (AP) station (non-AP STA), the apparatus comprising:
- memory;
- and
- processing circuitry to:
- encode a first frame for transmission to an AP, the first frame indicating that the non-AP STA is a wake-up radio (WUR) non-AP STA, the first frame indicating WUR capabilities of the non-AP STA;
- encode a second frame for transmission to the AP, the second frame comprising a WUR mode element indicating that the non-AP STA is requesting to enter WUR mode, the WUR mode element indicating duty cycle timing, including a duty cycle period, for operating in the WUR mode;
- wherein when the non-AP STA is in the WUR mode, the processing circuitry is configured to cause the non-AP STA to transition between an awake state and a doze state in accordance with the duty cycle timing,
- wherein when the non-AP STA is not in the WUR mode, the processing circuitry is configured to cause the non-AP STA to be in the awake state and refrain from transiting between the awake state and the doze state,
- wherein when the non-AP STA is in the WUR mode, the processing circuitry is configured to enable the non-AP STA to receive a WUR wake-up frame from the AP when the non-AP STA is in the doze state based on the duty cycle timing, and
- wherein in response to receipt of the WUR wake-up frame, the processing circuitry is configured to transition the non-AP STA from the doze state to the awake state.
A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of non-access point (AP) station (non-AP STA) to configure the non-AP STA to perform operations to:
- encode a first frame for transmission to an AP, the first frame indicating that the non-AP STA is a wake-up radio (WUR) non-AP STA, the first frame indicating WUR capabilities of the non-AP STA;
- encode a second frame for transmission to the AP, the second frame comprising a WUR mode element indicating that the non-AP STA is requesting to enter WUR mode, the WUR mode element indicating duty cycle timing, including a duty cycle period, for operating in the WUR mode;
- wherein when the non-AP STA is in the WUR mode, the processing circuitry is configured to cause the non-AP STA to transition between an awake state and a doze state in accordance with the duty cycle timing,
- wherein when the non-AP STA is not in the WUR mode, the processing circuitry is configured to cause the non-AP STA to be in the awake state and refrain from transiting between the awake state and the doze state,
- wherein when the non-AP STA is in the WUR mode, the processing circuitry is configured to enable the non-AP STA to receive a WUR wake-up frame from the AP when the non-AP STA is in the doze state based on the duty cycle timing, and
- wherein in response to receipt of the WUR wake-up frame, the processing circuitry is configured to transition the non-AP STA from the doze state to the awake state.
