Abstract

A small cell communication system may reduce interference occurring in a macro terminal through beamforming, even when using the same frequency resources as used by a macro communication system. For example, the small cell communication system may use a larger amount of radio resources than the macro communication system for transmission of feedback information in an uplink. For example, the small cell communication system may use a codebook having a larger size than a size of a codebook used by the macro communication system.
