Abstract:
A beam pattern of a base station antenna is refined when communicating with multiple aircraft, so that interference to adjacent beams from the base station are reduced. The method include receiving position locations from each of multiple aircraft. The method also include the receipt of an attitude of each of the aircraft as well as receipt of measurements of the pilot signals from each of the aircraft. The pilot signals were transmitted by the base station. The method also include the adjustment of an amplitude and a phase of a signal driving at least one antenna transmit element to refine the beam pattern. The adjustment is based at least in part on the pilot measurements, the position locations, and the attitude of each of the aircraft.
