Method and mobile station for autonomously determining an angel of arrival (A0A) estimation
First Claim
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:
- receiving 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 services to one of the plurality of sectors in the communication cell;
determining an antenna gain difference based on the information associated with the plurality of sectors; and
determining the angle of arrival (AOA) estimation within the mobile station based on the antenna gain difference.

Abstract
A method (900) and a mobile station (160) for autonomously determining an angle of arrival (AOA) estimation are described herein. The mobile station (160) may receive information associated with a plurality of sectors (200) from a base station (140) having a plurality of antennas. Each of the plurality of antennas may provide communication service to one of the plurality of sectors (200). The information associated with the plurality of sectors (200) may be an antenna pattern, a boresight, a downtilt, and a signal strength value associated with each of the plurality of antennas. Based on the information associated with the plurality of sectors (200), the mobile station (160) may determine an antenna gain difference, which in turn, is used to determine the angle of arrival (AOA) estimation.
