Abstract
A communication system is provided which includes different kinds of base stations such as a macro base station and a femto base station. This system may execute a method for controlling unfavorably occurring interference due to such different kinds of base stations. In the method, the femto base station sends a femtocell interference indication (FII) report to the resource allocation control unit when user equipment is connected to the femto base station. The FII report contains a request for the allocation of resources to avoid interference. Then the resource allocation control unit establishes a femto interference coordination (FIC) zone according to the received FII report. The FIC zone indicates a particular region used to define resources allocated to the femto base station. The resource allocation control unit may be the macro base station or a self-organizing network (SON) server.
