Abstract
Provided are an interference mitigation method and a base station device in a wireless communication system. The interference mitigation method to be performed by a base station comprises a step in which a serving base station measures interference from a terminal that belongs to a neighboring cell; a step of determining a beamforming vector of the neighboring cell on the basis of the measured interference; a step of transmitting the beamforming vector of the neighboring cell to a base station of the neighboring cell; and a step of feeding back, to a terminal that belongs to a serving cell, the beamforming vector of the serving base station determined on the basis of the beamforming vector of the neighboring cell.
