Forward link transmission power to a user terminal in a wireless communications system having a plurality of beams is controlled by identifying the location of a user terminal within one of the plurality of beams, and setting the forward link transmission power in response to the identified user terminal location. Identifying user terminal location may include receiving from the user terminal multiple signal power measurements, such as pilot signal measurements. From these measurements, a difference is calculated between a first of the signal power measurements that corresponds to a home beam and each of the other signal power measurements. If the largest of the calculated differences is greater than a predetermined threshold, it is concluded that the user terminal is within a beam central region. However, if the largest of the calculated differences is less than or equal to the predetermined threshold, then it is concluded that the user terminal is within a beam crossover region.
