Abstract

Methods, devices, and apparatuses for wireless communications in stations of a Neighbor Awareness network (NAN) cluster are disclosed that may utilize a default data path of a wireless network. A first station may receive a message from a second station, the message may identify whether the second station wants to utilize a default data path or a customized data path for subsequent data transmission. The first station may determine to utilize the default data path for data transmissions based at least in part on requirements of the first station and an identifier included in the message.

Claims

1. A method of wireless communication, comprising:

receiving at a first station a message from a second station;

determining whether to utilize a default data path for data transmissions based at least in part on the received message; and

transmitting data over the default data path based on the determining.

2. The method of claim 1, wherein determining whether to utilize the default data path comprises:

determining whether the message includes a path identifier; and

selecting the default data path upon determining that the message fails to include the path identifier.

3. The method of claim 1, wherein the message includes a path identifier, the path identifier indicating whether the default data path or a customized data path should be utilized for data transmission.

4. The method of claim 1, wherein determining whether to utilize the default data path further comprises:

determining that an application for the first station requires enhanced encryption feature or a custom data path, the determination based on requirements specified by the first station.

5. The method of claim 1, further comprising:

receiving an advertisement message from an anchor master device, the advertisement message included in a beacon comprising attributes associated with the default data path.

6. The method of claim 5, wherein the attributes include at least one of a selected channel and transmission schedule information of the default data path.

7. The method of claim 5, wherein the advertisement message is received during a periodic Neighbor Awareness network (NAN) discovery window.

8. The method of claim 7, wherein the advertisement message further identifies a data session window for the first station to transmit traffic over the default data path.

9. The method of claim 8, wherein transmitting data over the default data path includes transmitting during the identified data session window.

10. The method of claim 8, further comprising:

transmitting a traffic announcement during a paging window.

11. The method of claim 10, wherein the paging window duration is selected based in part on a number of devices participating on the default data path.

12. The method of claim 10, wherein the paging window occurs during a synchronized time interval and all stations on the default data path are in an active state during the paging window interval.

13. The method of claim 10, wherein the traffic announcement is transmitted using Traffic Indication Map (TIM) message.

14. The method of claim 10, wherein the traffic announcement is transmitted using Service Response Filter (SRF) field in NAN service discovery message.

15. The method of claim 1, further comprising:

synchronizing all stations on a Neighbor Awareness network (NAN) based in part on information received from beacons transmitted by the second station.

16. The method of claim 1, further comprising:

determining that the transmission of data over the default data path is completed; and

terminating the transmission over the default data path based on the determining.

17. The method of claim 1, further comprising:

determining that a service is unavailable; and

ceasing to transmit over the default data path based on the determining.

18. An apparatus for wireless communication, comprising:

a processor;

memory in electronic communication with the processor and instructions stored in the memory, wherein the instructions are executable by the processor to;

receive at a first station a message from a second station;

determine whether to utilize a default data path for data transmissions based at least in part on the received message; and

transmit data over the default data path based on the determining.

19. The apparatus of claim 18, wherein the instructions are executable by the processor to:

determine whether the message includes a path identifier; and

select the default data path upon determining that the message fails to include the path identifier.

20. The apparatus of claim 18, wherein the message includes a path identifier, the path identifier indicating whether the default data path or a customized data path should be utilized for data transmission.

21. The apparatus of claim 18, wherein the instructions are executable by the processor to:

determine that an application for the first station requires enhanced encryption feature or a custom data path, the determination based on requirements specified by the first station.

22. The apparatus of claim 18, wherein the instructions are executable by the processor to:

receive an advertisement message from a master device, the advertisement message comprising attributes associated with the default data path.

23. The apparatus of claim 22, wherein the attributes include at least one of a selected channel and transmission schedule information of the default data path.

24. The apparatus of claim 22, wherein the advertisement message is received during a periodic Neighbor Awareness network (NAN) discovery window.

25. The apparatus of claim 24, wherein the advertisement message further identifies a data session window for the first station to transmit traffic over the default data path.

26. The apparatus of claim 18, wherein the instructions are executable by the processor to:

synchronize all stations on a Neighbor Awareness network (NAN) based in part on information received from beacons transmitted by the second station.

27. A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

receive at a first station a message from a second station;

determine whether to utilize the default data path for data transmissions based at least in part on the received message; and

transmit data over the default data path based on the determining.

28. The computer-readable medium of claim 27, wherein the instructions are executable by the processor to:

determine that an application for the first station requires enhanced encryption feature or a custom data path, the determination based on requirements specified by the first station.

29. An apparatus for wireless communication, comprising:

means for receiving at a first station a message from a second station;

means for determining whether to utilize the default data path for data transmissions based at least in part on the received message; and

means for transmitting data over the default data path based on the determining.

30. The apparatus of claim 29, wherein means for determining whether to utilize the default data path comprises:

means for determining whether the message includes a path identifier; and

means for selecting the default data path upon determining that the message fails to include the path identifier.
