Abstract: The present invention relates to a method and an apparatus for performing cooperating carrier aggregation in a plurality of base stations in heterogeneous network systems. According to the present invention, inter-base station cooperating carrier aggregation allows wireless communication to be maintained between a terminal and a base station in a heterogeneous network environment, and a frequency band of another base station with excellent signal quality can be set as a secondary component carrier with respect to the terminal for service provision. Accordingly, a service bandwidth with respect to the terminal can be expanded, and unnecessary handover overhead between the base stations can be reduced. In addition, a load of the base station with concentrated traffic can be distributed to another base station, and wireless resource use and efficiency can be increased through inter-base station sharing of available resources.
