Abstract
Devices and methods of estimating the AoD of a STA are generally described. The STA receives and stores an association between tone and transmission angle for each tone transmitted by an AP in different angles. The association indicates that, for each angle, a tone transmitted in the angle is unique. The STA detects a symbol transmitted on each tone, determines the strength and timing of the tone and estimates the AoD based on the association and either or both the strength and timing. Each tone may have multiple symbols and/or each angle multiple tones whose characteristics are averaged to determine the appropriate characteristic of the particular tone or angle. The position of the STA is calculated from the AoD of one or more APs.
