Patent ID: 8412104

Claim:
A communication method of a first target terminal corresponding to a target base station of a target cell in a multi-cell communication system, the method comprising: receiving, 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; determining 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 transmitting, to the neighboring base station, information associated with the 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.
