Abstract: Provided are an apparatus and a method to coordinate inter-cell interference using a base station and statistical information on a terminal period channel to improve a processing rate of a heterogeneous network on which a large cell and a small cell are mixed in a mobile communication environment. When limited channel information is provided on the heterogeneous network, the present invention provides the interference coordination apparatus and the method to reduce the performance degradation due to the interference. In addition, according to the present invention, the apparatus and method can control the interference of which a macrocell base station is applied to a picocell terminal using feedback information to periodically transmit between the terminal and the base station and a large fading gain and terminal, from a channel model.
