Abstract: An apparatus and method for controlling interference between small-cell base stations by using multi-antenna beamforming. The apparatus includes a channel state information (CSI) estimator, a non-optimal beamforming factor calculator, an optimal beamforming factor calculator, and an interference controller. The apparatus and method control interference between small-cell base stations by calculating an optimal beamforming factor assuming that information exchange between base stations is limited in a small-cell downlink system and each base station knows only a channel value sent by itself or a channel value received by itself.

Abstract: Provided is a method of allocating a resource in a small cell system. The method includes: selecting a temporary base station for each user terminal; measuring a signal-to-noise ratio (SNR) through a downlink pilot in a small cell base station; transmitting the signal-to-noise ratio measured for each user terminal to the temporary base station; receiving base station selection and resource allocation information from the small cell base station; and selecting the small cell base station to which most frequency resource block are allocated as a home base station.
