    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.

    Abstract: In a navigation system and method, location-aware adjustments may be made to the accuracy and/or power of the navigation system by changing at least one setting of a navigation system receiver in response to at least one characteristic of a navigation route and/or an estimated current position of the receiver. By providing location-aware adjustments, the accuracy may be increased when a higher accuracy is desired and may be decreased when a lower accuracy is sufficient based on the receiver location. A higher accuracy setting may be used, for example, when the estimated current position of a navigation system receiver is within the vicinity of a waypoint along the navigation route and a lower accuracy setting may be used at other times to reduce power consumption. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

    Abstract: Embodiments of a communication station and method for time-of-flight (ToF) location determination in a wireless network are generally described herein. In some embodiments, a responding communication station receives a ToF measurement request. The responding communication station transmits an acknowledgment of the ToF measurement request. The responding communication station also transmits a response to the ToF measurement request that includes an indication of a time period for an initiating communication station to poll the responding communication station for a ToF result.

    Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of estimating a location of a mobile device. For example, an apparatus may include a controller to control a mobile device to transmit a first message to a wireless communication station (STA) and to receive a first acknowledgement (ACK) message from the STA in response to the first message, when the mobile device is at a first location, wherein the controller to control the mobile device to transmit a second message to the STA and to receive a second ACK message from the STA in response to the second message, when the mobile device is at a second location, wherein the controller is to determine a distance difference between a first distance and a second distance based on a first round trip time and a second round trip time, the first distance being between the first location and the STA, the second distance being between the second location and the STA, wherein the first round trip time includes a round trip time of the first message and first ACK, and the second round trip time includes a round trip time of the second message and second ACK.
