Abstract
The method operates in a wireless communication system, and includes receiving at a first base station having a first location, a widebeam signal from a first mobile communication unit having a second location; measuring, by the first base station, a characteristic of the received widebeam signal to form a first widebeam characteristic; receiving the widebeam signal at a second base station having a third location; measuring, by the second base station, the characteristic of the received widebeam signal to form a second widebeam characteristic; receiving, at the first base station, a narrowbeam signal from the first mobile communication unit; measuring, by the first base station, a characteristic of the received narrowbeam signal to form a first narrowbeam characteristic; receiving the narrowbeam signal at the second base station; measuring, by the second base station, the characteristic of the received narrowbeam signal to form a second narrowbeam characteristic; comparing the first widebeam characteristic and the first narrowbeam characteristic to form a first comparison value; comparing the second widebeam characteristic and the second narrowbeam characteristic to form a second …
