摘要：
A method of controlling femtocell interference considering a macrocell is provided. The method of controlling the interference includes a method of setting transmission power of the femtocell and methods of avoiding the interference of the femtocell. The methods of avoiding the interference include a PRB rotation method, a PRB transmission power restriction method, a hybrid method and a UB rotation method. The method of setting the transmission power and the methods of avoiding the interference may be implemented independently or implemented in combination with each other. Hence, according to the present invention, the femtocell itself can control the interference without affecting an interface of an existing macrocell base station and without signaling through the interface with the macrocell.
