Method and apparatus of controlling inter cell interference based on cooperation of intra cell terminals

A first target terminal corresponding to a target base station of a target cell in a multi-cell communication system, the first terminal comprising:

• a receiver configured to receive, from a second target terminal corresponding to the target base station, information associated with an interference channel from a neighboring base station of a neighboring cell to the second target terminal;
• a receive beamforming vector determining unit configured to determine a receive beamforming vector of the first target terminal based on information associated with an interference channel from the neighboring base station to the first target terminal and information associated with an interference channel from the neighboring base station to the second target terminal, so that an effective interference channel from the neighboring base station to the first target terminal that is associated with the receive beamforming vector of the first target terminal and an effective interference channel from the neighboring base station to the second target terminal that is associated with a receive beamforming vector of the second target terminal are aligned in the same spatial dimension;
• and
• a transmitter configured to transmit, to the neighboring base station, information associated with the effective interference channel from the neighboring base station to the first target terminal this associated with the receive beamforming vector of the first target terminal.
