ABSTRACT:
Systems and methods for adaptively forming a transmission beam to optimize data transmissions to one or more receivers (mobile stations). In one embodiment, a method comprises varying a transmission beam pattern by controlling a parameter such as the phase shift between a primary transmission signal and a secondary transmission signal. As the beam pattern is varied, data is collected on the performance of communications using the beam. The data is then examined to identify values of the control parameter for which performance is maximized. The control parameter is then maintained at these values for longer periods of time than those values for which performance is lower. Data throughput can thereby be increased for situations in which there are relatively few mobile stations in the sector.
