    摘要: 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.

    摘要: Provided is an interference aligning method and apparatus that does not perform full feed-forwarding in a hierarchical cell communication. A macro base station may generate respective transmission beamforming vectors of macro terminals to null interference channels to pico terminals and to remove interference among the macro terminals. The effective interference channels are based on reception beamforming vectors of the pico terminals. The macro base station may transmit, to a macro terminal, a feed-forward indicator (FFI) indicating a method of transmitting information associated with a reception beamforming vector of the macro terminal. The macro terminal may obtain information associated with the reception beamforming vector based on the FFI.
