Abstract

This disclosure describes systems, methods, and apparatus related to an extended neighbor list and optimized AP and wireless networks discovery. A device may cause to perform a scan across one or more frequency bands. The device may determine one or more access devices based at least in part on the scan. The device may generate an extended neighbor list (ENL) associated with the one or more access devices. The device may cause to send the ENL to one or more first devices.

Claims

1. A device comprising:

at least one memory that stores computer-executable instructions; and

at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to;

cause to perform a scan across one or more frequency bands;

determine one or more access devices based at least in part on the scan;

generate an extended neighbor list (ENL) associated with the one or more access devices; and

cause to send the ENL to one or more first devices.

2. The device of claim 1, wherein the ENL includes one of a frequency band, an operating channel, a service set identifier, or a target beacon transmission time.

3. The device of claim 1, wherein the one or more access devices include at least one of an access point, a neutral host, a software AP, or a Wi-Fi direct group owner device.

4. The device of claim 1, wherein the one or more access devices belong to a same extended service set.

5. The device of claim 1, wherein the one or more access devices belong to a different extended service set.

6. The device of claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to set an ENL bit in one or more frames.

7. The device of claim 6, wherein the one or more frames include at least in part, a beacon frame, a probe response frame, or a fast initial link set up (FILS) discovery frame.

8. The device of claim 1, wherein the scan is at least one of a passive scan, an active scan, an access network query protocol (ANQP), or an out of band configuration scan.

9. The device of claim 1, further comprising a transceiver configured to transmit and receive wireless signals.

10. The device of claim 9, further comprising one or more antennas coupled to the transceiver.

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

identifying one or more frames received from a device;

identifying an extended neighbor list (ENL) from at least one of the one or more frames; and

selecting an access device based at least in part on the ENL or a combination of ENLs from multiple APs and a preference setting.

12. The non-transitory computer-readable medium of claim 11, wherein the ENL includes at least in part a frequency band, an operating channel, a service set identifier (SSID), or a target beacon transmission time (TBTT).

13. The non-transitory computer-readable medium of claim 12, wherein the access device is at least one of an access point, a software AP, a neutral host, or a Wi-Fi direct group owner device.

14. The non-transitory computer-readable medium of claim 11, wherein the computer-executable instructions cause the processor to further perform operations comprising identifying one or more user preferences associated with selecting the access device.

15. The non-transitory computer-readable medium of claim 11, wherein the one or more frames include at least in part, a beacon frame, a probe response frame, or a fast initial link set up discovery frame.

16. A method comprising:

causing to perform a scan, by one or more processors, across one or more frequency bands;

determining one or more access devices based at least in part on the scan;

generating an extended neighbor list (ENL) associated with the one or more access devices; and

causing to send the ENL to one or more first devices.

17. The method of claim 16, wherein the ENL includes at least in part a frequency band, an operating channel, a service set identifier, or a target beacon transmission time.

18. The method of claim 16, wherein the one or more access devices include at least one of an access point, a software AP, a neutral host, or a Wi-Fi direct group owner device.

19. The method of claim 16, wherein the one or more access devices belong to a same extended service set.

20. The method of claim 16, wherein at least one of the one or more access devices belong to a different extended service set.
