Abstract:
Provided is a method and apparatus for controlling inter cell interference based on cooperation between intra cell terminals. The intra cell terminals may exchange interference channel information, and may determine a receive beamforming vector based on the exchanged interference channel information. At least one intra cell terminal may feed back, to a neighboring cell base station, information associated with an effective interference channel using the receive beamforming vector. A base station may determine a transmit beamforming vector based on information associated with an effective interference channel using receive beamforming vectors of neighboring cell terminals that are received from at least one neighboring cell terminal.
