Abstract
The present invention relates to an interference control method and an apparatus therefor in a heterogeneous system. To this end, the present invention relates to an interference control method for an almost blank subframe (ABS) ratio determination apparatus in a wireless communication system in which a cell range expansion (CRE) area is defined, comprising the steps of: receiving information about data load within a cell from one or more first cells, and one or more second cells; determining an ABS ratio on the basis of the wireless resource requirements of a CRE terminal with respect to the wireless resource requirements of all cells that are obtained from the data load information; and transmitting the determined ABS ratio to one of the first cells and the second cells.
