  • Publication number: 20170142734
    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.
