Abstract
A system and method are disclosed for coordinating the scheduling of beamformed data to reduce interference in a wireless system. A first optimum phase adjustment is determined to increase the gain of an intended signal at a mobile device. A second optimum phase adjustment is determined to decrease the gain of interfering signals received at the mobile device. Using a phase adjustment map, a transmission is scheduled at a base station within wireless resources using the first optimum phase adjustment, at the same time an interfering base station is transmitting at the second optimum phase adjustment angle. Thus, signal strength is greatly improved while interference is greatly reduced, improving the efficiency of the wireless system.
