The present invention relates to an interference management method in a heterogeneous network environment. The present invention can provide the interference management method in a heterogeneous network environment, comprising: a first step of measuring, by a terminal located in a coverage area of a macro cell base station, signal intensities from the macro cell base station and a small cell base station, and broadcasting or unicasting, by the small cell base station, data having a CRE value; a second step of transmitting a CRE flag value to the small cell base station by performing handoff to the small cell according to a comparison result of the signal intensities of the small cell base station and the macro cell base station from the first step; and a third step of counting the terminals by distinguishing the terminal located in a CRE area from the terminal located in a coverage area of the small cell base station, according to the CRE flag value received through the terminal in a predetermined measurement period unit, and transmitting counted data to the macro cell base station. |
