Abstract: A method of direction finding (DF) positioning based on a simplified antenna platform format in a wireless communication network is proposed. A receiver receives antenna platform format information of a transmitter having multiple antenna elements. The antenna platform format information comprises an antenna platform format indicator, antenna platform position and orientation information, a number of antenna elements, and switching delay, phase center, and polarization information for each antenna element. The receiver receives a plurality of direction finding sounding signals transmitted from the transmitter via the multiple antenna elements. The receiver performs a DF algorithm based on the plurality of DF sounding signals and the antenna platform format information and thereby estimating a DF solution. Finally, the receiver determines its own location information based on the estimated DF solution.
