Systems, methods, and devices for social proximity fine timing measurement requests multicast signaling

1. A method comprising:

receiving, by a first device, two or more fine timing measurement (FTM) requests from two or more other devices;

transmitting, by the first device, a service discovery frame (SDF) indicating an intent to respond to each of the two or more fine timing measurement (FTM) requests, wherein the SDF comprises information identifying a channel in which to perform FTM and a time and/or duration of an FTM window;

transitioning, by the first device, to the channel to perform a FTM flow; and

receiving, by the first device, two or more FTM frames sent by the two or more other devices.

2. The method according to claim 1 , wherein the first device is configured to limit a set of target devices for FTM by publishing a set of target devices for FTM.

3. The method according to claim 1 , wherein if the first device is not a requesting device, at least one of the two or more other devices transmits an FTM request to initiate a FTM flow.

4. The method according to claim 2 , wherein the target devices are identified by a Service Set ID (SSID), a Medium Access Controller (MAC) address, a Neighbor Awareness Networking (NAN) device ID, or a NAN Cluster Basic Service Set ID (BSSID).

5. The method according to claim 1 , wherein the two or more other devices are connected via a Wi-Fi network, IEEE 802.11 network, Social Wi-Fi network, or are a part of a Neighbor-Awareness Networking (NAN) cluster.

6. A device comprising:

a wireless controller configured to communicate with two or more other devices;

a non-transitory computer readable storage device including instructions stored thereon; and

one or more processor(s) to execute the instructions stored on the storage device, causing the device to perform operations of:

receiving two or more fine timing measurement (FTM) requests from the two or more other devices;

transmitting, by the wireless controller coupled to the one or more processor(s), a service discovery frame (SDF) indicating an intent to respond to each of the two or more fine timing measurement (FTM) requests, wherein the SDF comprises information identifying a channel in which to perform FTM and a time and/or duration to perform the FTM; and

transitioning, by the device, to the channel to perform a FTM flow.

7. The device according to claim 6 , wherein the device is configured to limit a set of target devices for FTM by publishing a set of target devices for FTM.

8. The device according to claim 6 , wherein if the device is not a requesting device, at least one of the two or more other devices transmits an FTM request to initiate a FTM flow.

9. The device according to claim 7 , wherein the target devices are identified by a Service Set ID (SSID), a Medium Access Controller (MAC) address, a Neighbor Awareness Networking (NAN) device ID, or a NAN Cluster Basic Service Set ID (BSSID).

10. The device according to claim 6 , wherein the device and the two or more devices are connected via a Wi-Fi network, IEEE 802.11 network, Social Wi-Fi network, or are a part of a Neighbor-Awareness Networking (NAN) cluster.

11. A non-transitory computer readable storage device including instructions stored thereon, which when executed by one or more processor(s) of a first mobile device, cause the first mobile device to perform operations of:

receiving two or more fine timing measurement (FTM) requests from two or more other mobile devices;

transmitting a service discovery frame (SDF) indicating an intent to respond to each of the two or more fine timing measurement (FTM) requests, wherein the SDF comprises information identifying a channel in which to perform FTM and a time and/or duration to perform the FTM; and

transitioning, by the first mobile device, to the channel to perform a FTM flow.

12. The storage device according to claim 11 , wherein the device is configured to limit a set of target devices for FTM by publishing a set of target devices for FTM.

13. The storage device according to claim 11 , wherein if the device is not a requesting device, at least one of the two or more other mobile devices transmits an FTM request to initiate a FTM flow.

14. The storage device according to claim 12 , wherein the target devices are identified by a Service Set ID (SSID), a Medium Access Controller (MAC) address, a Neighbor Awareness Networking (NAN) device ID, or a NAN Cluster Basic Service Set ID (BSSID).

15. The storage device according to claim 11 , wherein the first mobile device and the one or more mobile devices are connected via a Wi-Fi network, IEEE 802.11 network, a Social Wi-Fi network, or are a part of a Neighbor-Awareness Networking (NAN) cluster.

16. A system for communication between two or more devices, the system comprising:

a first device for receiving two or more fine timing measurement (FTM) requests and identifying at least a second device and third device that would like to measure proximity to the first device;

wherein the first device transmits a service discovery frame (SDF) indicating an intent to respond to each of the two or more fine timing measurement (FTM) requests,

wherein the SDF comprises information identifying a channel in which to perform FTM and a time and/or duration to perform the FTM, and

wherein the first device and the at least the second device and third device satisfy the service discovery frame transition to the channel requested by the first device to perform a FTM flow.

17. The system according to claim 16 , wherein the first mobile device and the at least the second device and the third device are connected via a Wi-Fi network, IEEE 802.11 network, a Social Wi-Fi network, or are a part of a Neighbor-Awareness Networking (NAN) cluster.

18. The system according to claim 16 , wherein the first device and the at least the second device and the third device comprise a wireless controller, a RF interface, and an antenna.
