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.
