Abstract

A method and system for negotiating capabilities in a wireless communication network are provided. The method includes generating an action frame including one or more information elements, where the one or more information elements include capability information for multiple frequency bands. The method further includes transmitting the action frame including the one or more information elements to wireless communication devices in a wireless communication network.

Claims

1. A method of negotiating capabilities in a wireless communication network environment, comprising:

generating an action frame comprising one or more information elements, wherein the one or more information elements comprises a multiband capability indicator and intent to become owner of a Peer to Peer (P2P) group; and

transmitting the action frame including the one or more information elements to one or more peer wireless communication devices in the wireless communication network environment.

2. The method of claim 1, wherein the one or more information elements comprise Peer to Peer (P2P) information elements.

3. The method of claim 1, wherein the one or more information elements comprise Wi-Fi Display (WFD) information elements.

4. The method of claim 1, wherein the multiband capability indicator indicates capability to support multiple bands.

5. The method of claim 1, wherein the intent to become the owner of the P2P group comprises a group owner intent value and a PBSS Control Point (PCP) factor.

6. The method of claim 5, wherein the intent value indicates intent to become owner of the P2P group during communication over a 2.4/5 frequency band.

7. The method of claim 5, wherein the PCP factor indicates intent to become owner of the P2P group during communication over 60 GHz frequency band.

8. The method of claim 1, wherein the action frame comprises at least one information element indicating support for uncompressed media data.

9. The method of claim 8, wherein the at least one information elements comprises sub elements indicating support for raw video format, support for multiple streams, support for fast session transfer (FST), support for seamless session maintenance feature, and capabilities for each of the multiple streams.

10. An apparatus comprising:

a processor configured for generating an action frame comprising one or more information elements, wherein the one or more information elements comprises capability information for multiple frequency bands; and

a Wi-Fi module configured for transmitting the action frame including the one or more information elements to one or more peer wireless communication devices in the wireless communication network environment.

11. The apparatus of claim 10, wherein the one or more information elements comprise Peer to Peer (P2P) information elements.

12. The apparatus of claim 10, wherein the one or more information elements comprise Wi-Fi Display (WFD) information elements.

13. The apparatus of claim 10, wherein the capability information for multiple frequency bands comprises a multiband capability indicator, intent to become owner of a P2P group, support for raw video format, support for uncompressed media data, support for multiple streams, support for fast session transfer (FST), support for seamless session maintenance feature, and capabilities for each of the multiple streams.

14. The apparatus of claim 13, wherein the multiband capability indicator indicates capability to support multiple bands.

15. The apparatus of claim 13, wherein the intent to become the owner of the P2P group comprises a group owner intent value and a PBSS Control Point (PCP) factor.

16. The apparatus of claim 15, wherein the intent value indicates intent to become owner of the P2P group during communication over a 2.4/5 frequency band.

17. The apparatus of claim 15, wherein the PCP factor indicates intent to become owner of the P2P group during communication over 60 GHz frequency band.

18. A non-transitory computer-readable storage medium having instructions stored therein, that when executed by a wireless communication device, cause the wireless communication device to perform a method comprising:

generating an action frame comprising one or more information elements, wherein the one or more information elements comprises capability information for multiple frequency bands; and

transmitting the action frame including the one or more information elements to one or more wireless communication devices in the Wi-Fi network environment.

19. The storage medium of claim 18, wherein the capability information for multiple frequency bands comprises a multiband capability indicator, intent to become owner of a Peer to Peer (P2P) group, support for raw video format, support for multiple streams, support for fast session transfer (FST), support for seamless session maintenance feature, and capabilities for each of the multiple streams.
