METHOD AND APPARATUS FOR TRANSCEIVING DATA USING PLURALITY OF CARRIERS IN MOBILE COMMUNICATION SYSTEM
First Claim
1. A communication method of a terminal in a mobile communication system, the method comprising:
- receiving a control message including secondary serving cell (SCell) configuration information on an SCell to be added and discontinuous reception (DRX) configuration information from a primary serving cell (PCell); and
applying, when the control message includes an indicator indicating that a first base station to which the SCell to be added belongs differs from a second eNB to which the PCell belongs, the DRX configuration to the serving cell of the first base station.

Abstract
The present invention relates to a method and apparatus for performing a discontinuous reception (DRX) operation while transceiving data using a plurality of carriers in a mobile communication system. The communication method for a terminal according to one embodiment of the present invention comprises receiving a control message, including setting information of a secondary serving cell (SCell) to be added and discontinuous reception setting information, from a primary serving cell (PCell) and applying, if the control message includes an indicator indicating that the first base station to which the SCell to be added belongs and the second base station to which the PCell belongs are different from each other, the DRX setting information to the serving cell of a first base station. According to one embodiment of the present invention, a discontinuous reception (DRX) operation is applied upon the occurrence of inter-base-station carrier aggregation, thus reducing battery consumption.
