Method and apparatus for controlling femtocell base station

摘要

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 includes receiving pilot signals from one or more macro cell base stations located in surroundings of a femtocell and measuring intensities of pilot signals, receiving use frequency information and pilot signal transmission power information from one or more macro cell base stations, determining a position of a femtocell within a reference macro cell according to an intensity of a reference pilot signal having a maximum signal intensity among received pilot signals, determining a use frequency of a femtocell according to a position of a femtocell, and determining a transmission power of a femtocell according to use frequency and an intensity of a reference pilot signal of a femtocell.
