Abstract

Systems and methods for formatting frames in neighborhood aware networks are described herein. One aspect of the subject matter described in the disclosure provides a method of communicating in a wireless neighborhood aware network (NAN). The method includes determining at least one connection setup information element indicating one or more connection parameters of the NAN. The method further includes determining at least one service identifier of the NAN. The method further includes generating a public action discovery frame comprising the at least one connection setup information element and the at least one service identifier. The method further includes transmitting, at a wireless device, the public action discovery frame.

First claim

What is claimed is:

1. A method for communicating in a wireless neighborhood aware network (NAN), comprising:
generating, by a first wireless device, a public action discovery frame comprising one or more type length value (TLV) fields, each of the one or more TLV fields comprising:
a service identifier associated with a respective service, and
a service-specific information container including data related to the respective service, the data comprising a first length field and a service-specific information field; and transmitting, by the wireless device, the public action discovery frame;
wherein at least one of the one or more TLV fields includes a ranging control field comprising at least one of a ranging information length or a ranging algorithm type.

2. The method of claim 1 , wherein at least one of the one or more TLV fields includes a private flag indicating whether a respective service-specific information container is parseable.

3. The method of claim 2 , wherein the private flag is included in a service control field of a respective TLV field.

4. The method of claim 1 , wherein at least one of the one or more TLV fields includes a requestor address.

5. The method of claim 1 , wherein the one or more TLV fields include a requestor address flag indicating whether a requestor address is included in the one or more TLV fields.

6. The method of claim 1 , wherein at least one of the one or more TLV fields includes a connection setup information element.

7. The method of claim 1 , wherein at least one of the one or more TLV fields includes at least one of a second length field, a service control field, a range control field, or a ranging information field.

8. The method of claim 1 , wherein at least one of the one or more TLV fields includes a service control field comprising at least one of a publish flag, a subscribe flag, a secure flag, or a range limited flag.

9. The method of claim 1 , wherein at least one service identifier included in the one or more TLV fields comprises all-ones or all-zeroes and indicates a NAN management operation.

10. The method of claim 1 , wherein the public action discovery frame further comprises a source address comprising an identifier of the wireless device.

11. The method of claim 1 , wherein the public action discovery frame further comprises a destination address that is the same as a Basic Service Set Identifier (BSSID) of the NAN.

12. The method of claim 6 , wherein the connection setup information element indicates WiFi direct connection establishment.

13. The method of claim 1 , wherein transmitting the public action discovery frame comprises transmitting the public action discovery frame during a discovery window associated with the NAN.

14. A wireless device configured to communicate in a wireless neighborhood aware network (NAN), comprising:
a processor configured to:
generate a public action discovery frame comprising one or more type length value (TLV) fields, each of the one or more TLV fields comprising:
a service identifier associated with a respective service, and
a service-specific information container including data related to the respective service, the data comprising a first length field and a service-specific information field; and

a transmitter configured to transmit, at the wireless device, the public action discovery frame;
wherein at least one of the one or more TLV fields includes a ranging control field comprising at least one of a ranging information length or a ranging algorithm type.

15. The wireless device of claim 14 , wherein at least one of the
one or more TLV fields includes a private flag indicating whether a respective service-specific information container is parseable.

16. The wireless device of claim 15 , wherein the private flag is included in a service control field of a respective TLV field.

17. The wireless device of claim 14 , wherein at least one of the one or more TLV fields includes a requestor address.

18. The wireless device of claim 14 , wherein at least one of the one or more TLV fields includes a requestor address flag indicating whether a requestor address is included in the one or more TLV fields.

19. The wireless device of claim 14 , wherein at least one of the one or more TLV fields includes a connection setup information element.

20. The wireless device of claim 14 , wherein at least one of the one or more TLV fields includes at least one of a second length field, a service control field, a range control field, or a ranging information field.

21. The wireless device of claim 14 , wherein at least one of the one or more TLV fields includes a service control field comprising at least one of a publish flag, a subscribe flag, a secure flag, or a range limited flag.

22. The wireless device of claim 14 , wherein at least one service identifier included in the one or more TLV fields comprises all-ones or all-zeroes and indicates a NAN management operation.

23. The wireless device of claim 14 , wherein the public action discovery frame further comprises a source address comprising an identifier of the wireless device.

24. The wireless device of claim 14 , wherein the public action discovery frame further comprises a destination address that is the same as a Basic Service Set Identifier (BSSID) of the NAN.

25. The wireless device of claim 19 , wherein the connection setup information element indicates WiFi direct connection establishment.

26. The wireless device of claim 14 , wherein the transmitter is configured to transmit the public action discovery frame during a discovery window associated with the NAN.

27. An apparatus for communicating in a wireless neighborhood aware network (NAN), comprising:
means for generating, by a first wireless device, a public action discovery frame comprising one or more type length value (TLV) fields, each of the one or more TLV fields comprising:
a service identifier associated with a respective service, and
a service-specific information container including data related to the respective service, the data comprising a first length field and a service-specific information field; means for transmitting, at the first wireless device, the public action discovery frame;
wherein at least one of the one or more TLV fields includes a ranging control field comprising at least one of a ranging information length or a ranging algorithm type.

28. A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:
generate, at a first wireless device, a public action discovery frame comprising one or more type length value (TLV) fields, each of the one or more TLV fields comprising:
a service identifier associated with a respective service, and
a service-specific information container including data related to the respective service, the data comprising a first length field and a service-specific information field; and

transmit, at the first wireless device, the public action discovery frame;
wherein at least one of the one or more TLV fields includes a ranging control field comprising at least one of a ranging information length or a ranging algorithm type.
