Abstract

The present invention relates to an apparatus and method for performing handover in a multiple component carrier system. The present invention discloses a state information generation unit for generating a candidate cell list in which the secondary serving cells are arranged based on the measurement results and generating validity criteria information which is a criterion used to determine the validity of the measurement results. According to the present invention, at the time of handover, a source BS and a target BS can accurately know a service providing situation before handover.
