Abstract: Disclosed are a method and an apparatus for controlling a femtocell base station which can effectively solve an inter-cell interference problem. A method of controlling a femtocell base station according to an exemplary embodiment of the present disclosure includes receiving pilot signals from one or more macro cell base stations located in surroundings of a femtocell and measuring intensities of the pilot signals; receiving use frequency information and pilot signal transmission power information from the one or more macro cell base stations; determining a position of the femtocell within a reference macro cell according to an intensity of a reference pilot signal having a maximum signal intensity among the received pilot signals; determining a use frequency of the femtocell according to the position of the femtocell; and determining a transmission power of the femtocell according to the use frequency and the intensity of the reference pilot signal of the femtocell.
