APPARATUS AND METHOD FOR OPERATING RESOURCE OF SMALL CELL IN WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for avoiding small cell interference in a wireless communication system which includes a macro Base Station (BS) and at least one small BS using the same frequency band are provided. The method includes, when receiving an interference avoidance resource request signal from at least one terminal to which a macro cell service is provided, determining a small BS which exerts interference on the terminal, determining an interference avoidance interval not used by the small BS which exerts the interference on the terminal, and allocating a resource to the terminal using a resource of the interference avoidance interval not used by the small BS.
