    Abstract: Fine Timing Measurement (FTM) Burst Management during Time-of-Flight (ToF) measurements in a wireless network separates FTM traffic from other traffic activity using two distinct Media Access Control (MAC) addresses and by coordinating access availability durations between FTM activity and other traffic. Communication stations save power by powering down receive paths between FTM frames. A communication station arranged for FTM Burst Management comprises physical layer circuitry and processors to use a first MAC address for FTM procedure signals, and a second MAC address that is distinct from the first MAC address for data and traffic signals other than FTM procedure signals, and exchange FTM procedure signals with the Access Point (AP) during scheduled FTM burst access availability periods using the first MAC address, and exchange other data and traffic signals with the AP during other access availability periods using the second MAC address.

    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: This disclosure describes systems, methods, and computer-readable media related to testing tools for devices. In some embodiments, a plurality of public keys may be received from a server via a secured network connection where each of the plurality of keys corresponds to a respective private key associated with an access point. A time-of-flight (ToF) measurement protocol may be initiated with one or more access points. Data generated by ToF measurement protocol with the one or more access points may be received. In some embodiments, the one or more access points may be authenticated based at least in part on the plurality of public keys.

    Abstract: This disclosure describes systems, methods, and devices related to uplink location measurement report (LMR) feedback. A device may perform availability window negotiation during a negotiation phase of a location determination associated with a first initiating device of one or more initiating devices. The device may determine a status of a first LMR associated with the first initiating device. The device may cause to send a polling request to one more initiating devices during a first availability window. The device may identify a polling response from at least one of the one or more initiating devices. The device may perform one or more sounding measurements with the at least one of the one or more initiating devices during a measurement phase. The device may cause to send a trigger frame to the at least one of the one or more initiating devices.

    Abstract: This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.

    Abstract: A next generation vehicle-to-everything (NGV) station (STA) operating as an initiating station (ISTA) for performing non-trigger-based NGV ranging may encode an NGV ranging null-data packet (NDP) announcement (NGV NDPA) frame for transmission to a responding station (RSTA) to initiate the non-trigger-based NGV ranging. The NGV STA may also encode an initiator-to-responder (I2R) NGV ranging null-data packet (NDP) (I2R NGV ranging NDP) for transmission following the NGV NDPA frame. The I2R NGV ranging NDP may be encoded in accordance with a NGV Ranging NDP format that may include an NGV signal field (NGV-SIG), a repeated NGV-SIG (RNGV-SIG), an NGV Short Training field (NGV-STF) and an NGV long training field (NGV-LTF). The NGV-LTF may include one or two sets of LTF symbols depending on a number of LTF symbol repetitions (LTF_REP). Each set of LTF symbols may have one or two LTF symbols depending on a number of spatial streams (NUM_SS) and the NGV-LTF may be encoded without a packet extension (PE).
