A method for controlling inter-cell interference in a wireless communication system that supports a plurality of component carriers (CCs) according to the present invention comprises the following steps: receiving priority information on the interference protection for each of a plurality of component carriers from at least one neighboring base station; measuring an intensity of the signal received from the at least one neighboring base station; and generating priority information for interference protection for each of a plurality of component carriers constructed for the base station, based on the received priority information and the measured intensity of the signal received from the at least one neighboring base station.
