Abstract: A method and apparatus for allocating a resource in a heterogeneous network environment are provided. In a heterogeneous network environment in which small cells and a macrocell are mixed, a macro base station divides an entire frequency band that is allocated to a corresponding macrocell into a plurality of Frequency Partitions (FPs). The macro base station allocates some of the plurality of FPs to small cells that are included in the macrocell.
