Method and apparatus for transceiving data using plurality of carriers in mobile communication system

摘要

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.

主权项

1. A communication method of a terminal in a mobile communication system, the method comprising:
receiving, from a primary serving cell (PCell), a first control message including secondary serving cell (SCell) configuration information for an SCell and discontinuous reception (DRX) configuration information; applying, when the first control message includes an indicator indicating that a first base station for the SCell is different from a second base station for the PCell, the DRX configuration information to the SCell of the first base station; receiving a second control message including a DRX media access layer (MAC) control element (CE); determining whether the DRX MAC CE is received from a non-primary set serving cell or a primary set serving cell; and stopping, if the DRX MAC CE is received from the non-primary set serving cell, the DRX timer for the non-primary set serving cell.
