APPARATUS AND METHOD FOR ACTIVATING A COMPONENT CARRIER IN A MULTIPLE COMPONENT CARRIER SYSTEM

摘要

Provided is an apparatus and method for activating a component carrier in a multiple component carrier system. The present description discloses the steps of: receiving component carrier setting information about a first uplink component carrier, which is connected with a first downlink component carrier corresponding to a secondary serving cell of a terminal, from a base station; setting the first uplink component carrier on the basis of the component carrier setting information; and activating the initial state of the set first uplink component carrier according to the activation state of the first downlink component carrier. According to the present invention, the ambiguity of the initial state of an uplink component carrier additionally set between the terminal and the base station can be removed.
