Abstract

This disclosure describes systems, methods, and devices related to traffic indication map (TIM) piggybacking. A device may determine a frame including one or more TIMs indicating that the device has data to send in a first frequency band of a plurality of supported frequency bands. The device may cause to send the frame in a second frequency band of the plurality of supported frequency bands, wherein the first frequency band is different from the second frequency band, wherein the frame indicates a request for a first station device to be awake in the first frequency band to receive the data. The device may cause to send the data using the first frequency band.

Claims

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

determine a frame including one or more traffic indication maps (TIMs) indicating that the device has data to send in a first frequency band of a plurality of supported frequency bands;

cause to send the frame in a second frequency band of the plurality of supported frequency bands, wherein the first frequency band is different from the second frequency band, wherein the frame indicates a request for a first station device to be awake in the first frequency band to receive the data; and

cause to send the data using the first frequency band.

2. The device of claim 1, wherein the first station device supports multi-band operations, comprising two or more of a 2.4 GHz band, a 5 GHz band, or a 6 GHz band.

3. The device of claim 1, wherein the frame further includes an association identifier associated with the first station device.

4. The device of claim 1, wherein the one or more TIMs include a first TIM and a second TIM, wherein the first TIM is associated with the first frequency band, and wherein the second TIM is associated with the second frequency band.

5. The device of claim 1, wherein a size of the one or more TIMs is based on a number of the first station device operating in the second frequency band.

6. The device of claim 1, wherein the frame further includes a first association identifier associated with the first frequency band and a second association identifier associated with the second frequency band, wherein the first association identifier and the second association identifier are associated with a first station device radio of the first station device.

7. The device of claim 4, wherein the frame comprises an Element ID indicating that the first TIM is for multi-band (MB), and wherein the frame further comprises a band field indicating to the first station device that a target frequency band is associated with the first TIM.

8. The device of claim 1, wherein the at least one of the one or more TIMs conveys traffic information of a target frequency band.

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

determine a frame including one or more traffic indication maps (TIMs) indicating that the device has data to send in a first frequency band of a plurality of supported frequency bands;

cause to send the frame in a second frequency band of the plurality of supported frequency bands, wherein the first frequency band is different from the second frequency band, wherein the frame indicates a request for a first station device to be awake in the first frequency band to receive the data; and

cause to send the data using the first frequency band.

10. The non-transitory computer-readable medium of claim 9, wherein the first station device supports multi-band operations, comprising two or more of a 2.4 GHz band, a 5 GHz band, or a 6 GHz band.

11. The non-transitory computer-readable medium of claim 9, wherein the frame further includes an association identifier associated with the first station device.

12. The non-transitory computer-readable medium of claim 9, wherein the one or more TIMs include a first TIM and a second TIM, wherein the first TIM is associated with the first frequency band, and wherein the second TIM is associated with the second frequency band.

13. The non-transitory computer-readable medium of claim 9, wherein a size of the one or more TIMs is based on a number of the first station device operating in the second frequency band.

14. The non-transitory computer-readable medium of claim 9, wherein the frame further includes a first association identifier associated with the first frequency band and a second association identifier associated with the second frequency band, wherein the first association identifier and the second association identifier are associated with a first station device radio of the first station device.

15. The non-transitory computer-readable medium of claim 12, wherein the frame comprises an Element ID indicating that the first TIM is for multi-band (MB), and wherein the frame further comprises a band field indicating to the first station device that a target frequency band is associated with the first TIM.

16. The non-transitory computer-readable medium of claim 9, wherein the at least one of the one or more TIMs conveys traffic information of a target frequency band.

17. A method comprising:

determining a frame including one or more traffic indication maps (TIMs) indicating that the device has data to send in a first frequency band of a plurality of supported frequency bands;

causing to send the frame in a second frequency band of the plurality of supported frequency bands, wherein the first frequency band is different from the second frequency band, wherein the frame indicates a request for a first station device to be awake in the first frequency band to receive the data; and

causing to send the data using the first frequency band.

18. The method of claim 17, wherein the first station device supports multi-band operations, comprising two or more of a 2.4 GHz band, a 5 GHz band, or a 6 GHz band.

19. The method of claim 17, wherein the frame further includes an association identifier associated with the first station device.

20. The method of claim 17, wherein the one or more TIMs include a first TIM and a second TIM, wherein the first TIM is associated with the first frequency band, and wherein the second TIM is associated with the second frequency band.
