Abstract: The present invention proposes an apparatus and a method capable of forming M*N number of beams by a base station, which supports signal transmission/reception of the macro service area in heterogeneous networks in which a macro service area is formed with the M*N number of beams through a two-dimensional arrangement simultaneously considering the horizontal dimension and the vertical dimension and at least one small service is formed in the macro service area. To this end, at least one interference prediction beam formed to transmit signals interfering in transmission signals in at least one small service area from among the signals to be transmitted by the M*N number of beams is selected, and each of the M*N number of beams is formed in consideration of the inter-cell interference in at least one small service area due to the signals to be transmitted by at least one selected interference prediction beam.
