METHOD AND SYSTEM FOR REFINING A LOCATION OF A BASE STATION AND/OR A MOBILE DEVICE BASED ON SIGNAL STRENGTH MEASUREMENTS AND CORRESPONDING TRANSMITTER AND/OR RECEIVER ANTENNA PATTERNS
摘要:
A mobile device receives data transmissions, via a coupled receiver antenna array, from a transmitter antenna array of a serving base station. The mobile device determines relative distances, with respect to the serving base station, associated with signal strength measurements on the received data transmissions. The signal strength measurements are compensated, at the mobile device and/or a remote location server, in three-dimensional space based on corresponding transmitter and/or receiver antenna pattern, and/or mobile orientation information for estimating the relative distances. The estimated relative distances are refined by fitting a function of the azimuth and elevation angles. A location for the serving base station and/or the mobile device is determined or refined based on the refined relative distances to be shared among a plurality of users of the remote location server. Fixed or adaptive antenna patterns are supported at the serving base station and/or the mobile device.
