    Abstract: This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection. A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

    Abstract: This disclosure describes systems, methods, and computer-readable media related to adaptively changing availability of neighbor awareness networking (NAN) devices for post-NAN activities. In some embodiments, a first NAN enabled device may generate a NAN service discovery frame. The first NAN enabled device may transmit the NAN service discovery frame to a plurality of NAN enabled devices during a discovery window of the NAN. A request frame from a second NAN enabled device may be received based at least in part on transmitting the NAN service discovery frame. A response frame may be transmitted to the second NAN enabled device. A second NAN service discovery frame may be generated and include an updated availability bitmap based at least in part on data received in the request frame from the second NAN enabled device. The first NAN enabled device may transmit the second NAN service discovery frame.

    Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of performing a Time of Flight (ToF) measurement. For example, a first wireless device may include a controller to perform a Time of Flight (ToF) measurement procedure with a second wireless device; and a radio to communicate with the second wireless device a ToF frame including a first time value of a Time Synchronization Function (TSF) of a sender of the frame to indicate a beginning time of a ToF measurement period, and a second time value of the TSF at transmission of the ToF frame.

    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.
