    Abstract: Embodiments of a communication station and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, a ToF cooperation table may be received by a positioning station from an access point. The ToF cooperation table may identify one or more cooperating stations and may include information about each cooperating station for ToF positioning. A ToF positioning protocol may be performed with at least some of the cooperating stations identified in the ToF cooperation table using the information in the ToF cooperation table. During the ToF positioning protocol, a current position and a station positional accuracy may be received from each cooperating station. The current position may be a position when ToF is measured. A location of the positioning station may be determined based on the current positions and the ranges to each of the cooperating stations determined from the ToF positioning protocol.

    Abstract: Navigation systems for use in indoor environments may include a navigation system that can calculate a time of flight of signals between a navigation device and a WiFi® Access Point. Such a calculation can be more accurate not just by using more accurate oscillators in devices, but by correcting a relative error between two devices. This relative error may be found by determining a timing offset correction, a difference in accuracy between the navigation device and the WiFi® Access Point. This may be performed by performing a fine frequency estimation on a long training field or by receiving a parts per million (ppm) offset from another device. Once the ppm offset is determined, the accuracy of the navigation device can be improved by a factor of 50 using a series of equations described in the disclosure.

    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.
