Abstract

This disclosure describes systems, methods, and devices related to wake-up radio (WUR) advertisement channels. A device may include a wake-up receiver (WURx) and a primary connectivity radio. The device may determine a wake-up radio (WUR) discovery subchannel for WUR advertisement. The WUR discovery subchannel may be associated with a channel of a frequency band. The device may generate a WUR discovery frame comprising a WUR advertisement. The device may transmit, by the WURx, the WUR discovery frame to a second device using the WUR discovery subchannel. The device may identify a response from the second device indicating an acknowledgment of the WUR discovery frame.

Claims (47)

1. A device for communicating a wake-up radio (WUR) channel, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:

identify a first time period during which a WUR of a station device is to be awake, the first time period negotiated by the device and the station device;

identify a WUR channel associated with discovery of the device;

generate a frame comprising an indication of the WUR channel; and

cause to send the frame to the station device during a second time period, wherein the second time period is outside of the first time period.

2. The device of claim 1 , wherein the WUR channel is channel 44 of a 5 GHz frequency band.

3. The device of claim 1 , wherein the WUR channel is channel 149 of a 5 GHz frequency band.

4. The device of claim 1 , wherein the WUR channel is in a 2.4 GHz frequency band.

5. The device of claim 1 , wherein the processing circuitry is further configured to:

identify a second WUR channel associated with discovery of the device;

generate a second frame associated with discovery of the device;

generate a third frame associated with discovery of the device;

cause to send the second frame using the WUR channel; and

cause to send the third frame using the second WUR channel.

6. The device of claim 5 , wherein the second frame is a same type of frame as the third frame, and wherein the second frame is a different type of frame than the frame.

7. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals, the wireless signals comprising the frame.

8. The device of claim 7 , further comprising one or more antennas coupled to the transceiver.

9. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

identifying, by an access point device, a first time period during which a wake-up radio (WUR) of a station device is to be awake, the first time period negotiated by the access point device and the station device;

identifying a WUR channel associated with discovery of the access point device;

generating a frame comprising an indication of the WUR channel; and

causing to send the frame to the station device during a second time period, wherein the second time period is outside of the first time period.

10. The non-transitory computer-readable medium of claim 9 , wherein the WUR channel is channel 44 of a 5 GHz frequency band.

11. The non-transitory computer-readable medium of claim 9 , wherein the WUR channel is channel 149 of a 5 GHz frequency band.

12. The non-transitory computer-readable medium of claim 9 , wherein the WUR channel is in a 2.4 GHz frequency band.

13. The non-transitory computer-readable medium of claim 9 , the operations further comprising:

identifying a second WUR channel associated with discovery of the access point device;

generating a second frame associated with discovery of the access point device;

generating a third frame associated with discovery of the access point device;

causing to send the second frame using the WUR channel; and

causing to send the third frame using the second WUR channel.

14. The non-transitory computer-readable medium of claim 13 , wherein the second frame is a same type of frame as the third frame, and wherein the second frame is a different type of frame than the frame.

15. A method comprising:

identifying, by processing circuitry of an access point device, a first time period during which a wake-up radio (WUR) of a station device is to be awake, the first time period negotiated by the access point device and the station device;

identifying a WUR channel associated with discovery of the access point device;

generating a frame comprising an indication of the WUR channel; and

causing to send the frame to the station device during a second time period, wherein the second time period is outside of the first time period.

16. The method of claim 15 , wherein the WUR channel is channel 44 of a 5 GHz frequency band.

17. The method of claim 15 , wherein the WUR channel is channel 149 of a 5 GHz frequency band.

18. The method of claim 15 , wherein the WUR channel is in a 2.4 GHz frequency band.

19. The method of claim 15 , further comprising:

identifying a second WUR channel associated with discovery of the access point device;

generating a second frame associated with discovery of the access point device;

generating a third frame associated with discovery of the access point device;

causing to send the second frame using the WUR channel; and

causing to send the third frame using the second WUR channel.

20. The method of claim 19 , wherein the second frame is a same type of frame as the third frame, and wherein the second frame is a different type of frame than the frame.
