Abstract
Certain embodiments herein relate to a dynamic pre-association between Neighbor Awareness Networking (NAN) discovery windows and fine timing measurement (FTM) communications. A wireless station may trigger an FTM procedure during a NAN discovery window by the transmission of a NAN Service Discovery Frame (SDF). In addition to the FTM communications, an indication of a discovery window for which a subsequent FTM communication is expected to occur is also transmitted. In some embodiments, an FTM range report may also be transmitted with the indication.
Claims20
A neighbor awareness networking (NAN) device for performing a fine timing measurement (FTM) with a peer device, the NAN device comprising memory and processing circuitry configured to:
- cause to send a first NAN service discovery frame to the peer device, the first NAN service discovery frame comprising an indication of a first window associated with the NAN device;
- receive, from the peer device, a second NAN service discovery frame comprising an indication of a second window associated with the peer device;
- cause to send an FTM request to the peer device during the second window, wherein the FTM request comprises an indication of a third window;
- receive, from the peer device, during the third window, an FTM frame;
- and
- cause to send an FTM range report to the peer device, the FTM range report comprising an indication of a range based on the FTM frame.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
- receiving, at a first device from a second device, a first neighbor awareness networking (NAN) service discovery frame comprising an indication of a first window associated with the second device;
- causing to send, to the second device, a second NAN service discovery frame comprising an indication of a second window associated with the first device;
- receiving, at the first device from the second device, a fine timing measurement (FTM) request during the second window, the FTM request comprising an indication of a third window associated with the second device;
- and
- causing to send, to the second device during the third window, an FTM frame.
A method for performing a fine timing measurement (FTM) with a peer device, the method comprising:
- causing to send, by one or more processors of a neighbor awareness networking (NAN) device, to the peer device, a first NAN service discovery frame comprising an indication of a first window associated with the NAN device;
- receiving, by the one or more processors, from the peer device, a second NAN service discovery frame comprising an indication of a second window associated with the peer device;
- causing to send, by the one or more processors, an FTM request to the peer device during the second window, wherein the FTM request comprises an indication of a third window;
- receiving, by the one or more processors, from the peer device, during the third window, an FTM frame;
- and
- causing to send, by the one or more processors, an FTM range report to the peer device, the FTM range report comprising an indication of a range based on the FTM frame.
