Abstract:
1. A method of reducing interference in a communication system, the method comprising: first determining, by a transmitter, a first interfering beam of a first interfering transmitter; second determining, by the transmitter, a first transmission beamforming vector such that a beam from the transmitter directly opposes the first interfering beam at a first time and is transmitted at an opposite angle than the first interfering beam at the first time; reducing the interference by reducing an effect of the first interfering beam that directly opposes the beam from the transmitter; third determining, by the transmitter, a second interfering beam of a second interfering transmitter; fourth determining, by the transmitter, a second transmission beamforming vector such that a second beam from the transmitter conflicts with the second interfering beam; and transmitting, by the transmitter, using the first and second transmission beamforming vectors.
