Abstract

This disclosure describes systems, methods, and devices related to multi-band opportunistic power saving. A device may determine a first traffic indication associated with a first frequency band and a second traffic indication associated with a second frequency band. The device may determine a first power save indication associated with a station device and the first frequency band. The device may determine a second power save indication associated with the station device and the second frequency band. The device may generate a frame including the first traffic indication, the second traffic indication, the first power save indication, and the second power save indication. The device may send the frame using the first frequency band.

Claims

1. A device comprising storage coupled to processing circuitry, the processing circuitry configured to:

determine a first traffic indication associated with a first frequency band and a second traffic indication associated with a second frequency band;

determine a first power save indication associated with a station device and the first frequency band;

determine a second power save indication associated with the station device and the second frequency band;

generate a frame comprising the first traffic indication, the second traffic indication, the first power save indication, and the second power save indication; and

cause to send the frame using the first frequency band.

2. The device of claim 1, wherein the frame is a first opportunistic power save (OPS) frame, the processing circuitry is further configured to cause to send, to the station device and using the first frequency band, a second OPS frame, wherein the station device is absent from the first traffic indication, and wherein the second OPS frame is sent before the first OPS frame.

3. The device of claim 2, wherein the second OPS frame comprises a third power save indication associated with the station device and the first frequency band, and wherein the first OPS frame is sent during a time period associated with the third power save indication and using the second frequency band.

4. The device of claim 3, wherein the second OPS frame further comprises a third traffic indication associated with the first frequency band.

5. The device of claim 3, wherein the first power save indication is associated with a second time period that directly follows the time period.

6. The device of claim 3, wherein the first traffic indication indicates data to be sent to the station device before expiration of the time period.

7. The device of claim 6, wherein the processing circuitry is further configured to:

identify a power save poll received from the station device; and

cause to send the data to the station device.

8. The device of claim 1, wherein the station device is absent from the first traffic indication and the second traffic indication.

9. The device of claim 1, wherein the frame is a multi-band frame sent using the second frequency band.

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

11. The device of claim 10, further comprising an antenna coupled to the transceiver.

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

identifying, by a station device, a first frame received from an access point device, wherein the first frame is received using a first frequency band;

determining that the first frame comprises a first power save indication associated with the first frequency and a second power save indication associated with a second frequency;

determining that the first frame comprises a first traffic indication associated with the first frequency band and a second traffic indication associated with the second frequency band; and

determining a power state based on the second traffic indication.

13. The non-transitory computer-readable medium of claim 12, the operations further comprising:

determining that the station device is absent from the second traffic indication, wherein the power state is based on the absence; and

causing the station device to enter a power save mode during a time period associated with the second power save indication.

14. The non-transitory computer-readable medium of claim 12, the operations further comprising:

determining that the second traffic indication comprises an indication of the station device, wherein the power state is based on the indication of the station device; and

causing the station device to activate a radio during a time period associated with the second power save indication.

15. The non-transitory computer-readable medium of claim 12, wherein the first frame is a first opportunistic power save (OPS) frame, the operations further comprising identifying a second OPS frame received from the access point device using the first frequency band, wherein the station device is absent from the first traffic indication, and wherein the second OPS frame is received before the first OPS frame.

16. The non-transitory computer-readable medium of claim 15, wherein the second OPS frame comprises a third power save indication associated with the station device and the first frequency band, and wherein the first OPS frame is received during a time period associated with the third power save indication and using the second frequency band.

17. The non-transitory computer-readable medium of claim 16, wherein the second OPS frame further comprises a third traffic indication associated with the first frequency band.

18. A method, comprising:

determining, by processing circuitry of an access point, a first traffic indication associated with a first frequency band and a second traffic indication associated with a second frequency band;

determining a first power save indication associated with a station device and the first frequency band;

causing to send the frame using the first frequency band.

19. The method of claim 18, wherein the frame is a first opportunistic power save (OPS) frame, further comprising causing to send, to the station device and using the first frequency band, a second OPS frame, wherein the station device is absent from the first traffic indication, and wherein the second OPS frame is sent before the first OPS frame.

20. The method of claim 19, wherein the second OPS frame comprises a third power save indication associated with the station device and the first frequency band, and wherein the first OPS frame is sent during a time period associated with the third power save indication and using the second frequency band.
