DEVICE AND METHOD FOR RECONFIGURING COMPONENT CARRIER IN WIRELESS COMMUNICATION SYSTEM THAT OPERATES PLURALITY OF COMPONENT CARRIERS, AND DEVICE AND METHOD FOR TRANSMITTING RRC CONNECTION-RECONFIGURATION MESSAGE THEREFOR

摘要

The present description relates to a device and a method for reconfiguring a component carrier (CC) of a UE in a wireless communication system that operates a plurality of CCs. The UE receives an RRC connection-reconfiguration message, performs a CC reconfiguration procedure for adding, modifying, and releasing functions or the like of a corresponding CC for the UE by using CC configuration information contained in a CC connection-reconfiguration message, and generates a CC reconfiguration completed message to transmit the generated message to an eNB. Since the present description defines CC index information mapped into each CC by using CC unique information, later the CCs can be divided by using only the received CC index information even without the CC unique information, whereby efficient CC reconfiguration plans are made.
