Abstract: A base station of a carrier aggregation system performs interference control of a first component carrier in which interference exceeds a threshold value among a plurality of component carriers based on an ABS pattern and changes the first component carrier to an available new component carrier, when interference of the first component carrier exceeds a threshold value after the interference control is performed.

Abstract: According to an exemplary embodiment of the present invention, a master base station selects a target serving cell in which a state is changed, among the serving cells of at least one slave base station set in the terminal, generates a MAC control element which instructs a state change of the target serving cell, and then directly transmits the MAC control element to the terminal in the case of an uplink asynchronous state between the target slave base station managing the target serving cell and the terminal.
