Apparatus and method for performing inter-cell interference coordination using limited channel state information in heterogeneous network

Abstract

Disclosed herein are an apparatus and method of performing inter-cell interference coordination in a heterogeneous network. The apparatus includes a reception unit, a determination unit, a generation unit, and a transmission unit. The reception unit receives a modulation and coding scheme (MCS) level from a small cell base station in each frame. The determination unit determines a calculated MCS level based on the MCS level and an interfering signal estimated through probabilistic modeling. The generation unit generates a ratio of subframes, in which data will not be transmitted, to all subframes of a frame based on the MCS level and the calculated MCS level. The transmission unit transmits the ratio and the calculated MCS level to the small cell base station.
