Abstract:
1. In a wireless communication system, wherein a communication cell includes a plurality of sectors, a method for autonomously determining an angle of arrival (AOA) estimation of a mobile station, the method comprising: requesting within the mobile station information associated with the plurality of sectors from a base station having a plurality of antennas, each of the plurality of antennas providing communication service to one of the plurality of sectors in the communication cell; receiving the requested information associated with the plurality of sectors; determining a signal difference between a first downlink signal and a second downlink signal based on the requested information associated with the plurality of sectors, the first downlink signal being associated with a first antenna of the base station and the second downlink signal being associated with a second antenna of the base station; normalizing the first and second downlink signals to determine an antenna gain difference between the first and second downlink signals; and determining a bearing along the first downlink signal in which the signal difference matches the antenna gain difference, the first downlink signal having greater signal strength than the second downlink signal.
