1. A resource allocation method by a macro base station in a heterogeneous network system, the method comprising:
- generating an almost blank subframe (ABS) pattern based on a type of data, the data being transmitted from the macro base station to a user equipment (UE) via higher layer signaling; and
performing data communication using radio resources based on the ABS pattern,wherein the ABS pattern is reconfigured by a pico base station when a signal is configured to be transmitted by the macro base station in an ABS according to the ABS pattern.

Abstract
The present invention relates to a method and an apparatus for applying wireless resources in order to control inter-cell interference in a heterogeneous network system. The method for applying wireless resources provided by the present invention generates an almost blank subframe (ABS) pattern on the basis of the type of data transmitted from at least one of a first base station and a second base station, applies a non-ABS or an ABS to wireless resources of the first base station according to the generated ABS pattern, and performs data communication by using the wireless resources to which the ABS has been applied.
