    Abstract: Some aspects relate to an apparatus, method and/or system of radar tracking. For example, a radar tracker may be configured to generate target tracking information corresponding to a plurality of targets in an environment of a radar device. For example, the radar tracker may include a processor configured to determine the target tracking information based on a plurality of multi-target density functions corresponding to a respective plurality of target types, and to update the plurality of multi-target density functions based on detection information corresponding to a plurality of detections in the environment. For example, the radar tracker may include an output to output the target tracking information.

    Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of Collaborative Time of Arrival (CToA). For example, an apparatus may include circuitry and logic configured to cause a CToA broadcasting wireless communication station (STA) (bSTA) to broadcast an announcement frame to announce a ranging-to-self sequence of a CToA measurement protocol; to broadcast a first ranging measurement frame of the ranging-to-self sequence subsequent to the announcement frame; to broadcast a second ranging measurement frame of the ranging-to-self sequence subsequent to the first ranging measurement frame; and to broadcast a Location Measurement Report (LMR) frame of the ranging-to-self sequence subsequent to the second ranging measurement frame, the LMR frame including a Time of Departure (ToD) of the first ranging measurement frame.

    Abstract: The disclosure generally relates to an enhanced positioning system and method using a combination or hybrid filter. In one embodiment, Time-Of-Flight (ToF) measurements are used to determine an approximate location for a mobile device in relationship to one or more Access Points. The ToF combined with known and unknown variables are then processed through a hybrid filter system to determine location of the mobile device. The hybrid filter system may include a Kalman Filter (KF) for processing linear models and generally Gaussian noise distribution. The KF assumes that the state probability of mobile device location is Gaussian. Such variables include, for example, WiFi ToF bias. The hybrid filter system may include a Bayesian Filter (BF) for processing variables having non-Gaussian noise distribution and non-linear models. Such variables include, for example, the coordinates of the mobile device. A probability determination from each of the KF and BF is then applied to estimate the mobile device location.

    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: Systems and methods are directed to use of a neighbor list for wireless indoor navigation. The neighbor list may include related information regarding all neighboring access points (APs). The neighbor list can be transmitted, at least partially, to include the related information of a desired number of or all APs in the neighbor list from one AP to a wireless device. The neighbor list can be transmitted in a Neighbor Report Response (NRR) or a time-of-flight (ToF) Response and allow the wireless device to scan for minimal number of APs for ToF measurements. By using the neighbor list, power consumption and time can be significantly reduced during wireless indoor navigation.
