WIRELESS COMMUNICATION SYSTEM AND METHOD FOR MANAGING RESOURCE FOR INTERFERENCE COORDICATION THEREOF

摘要

The present invention relates to a wireless communication system and a method for managing resources for interference coordination in the system. According to an embodiment of the present invention, a communication method of a base station may comprise the following steps of determining an aggregate interference caused by a terminal in a heterogeneous cell; transmitting information about the aggregate interference to a higher layer node entity; receiving information about an almost blank subframe (ABS) pattern from the higher node entity; and configuring an ABS by using the received information about the ABS pattern. According to the embodiment of the present invention, since an X2 interface between a pico base station and a macro base station is unnecessary, the overhead between the pico base station and the macro base station can be reduced, thereby enhancing the performance of the pico base station.
