Abstract: The present invention relates to a method of selecting, by an eNB, a PCC for UE in a multiple component carrier system. The method includes obtaining mobility state information about the UE and coverage information and load information about carriers managed by the eNB; determining whether or not a mobility state value of the UE is greater than a specific threshold based on the obtained mobility state information; and selecting the PCC based on the load information if, as a result of the determination, the mobility state value is greater than the specific threshold. In accordance with the present invention, a BS adaptively selects a PCC by taking the load state of a carrier (or cell), UE mobility velocity, and the coverage of each carrier (or cell) into consideration.
