Abstract: The present invention relates to a method and apparatus for transmitting data using a multi-carrier in a mobile communication system. The method of transmitting data in user equipment of a wireless communication system using a carrier aggregation technique according to an embodiment of the present invention includes setting secondary cells included in an S-TAG (Secondary-Timing Advance Group) configured of only secondary cells (SCells), deactivating a downlink timing reference cell in the S-TAG; determining whether other activated secondary cells exist besides the deactivated downlink timing reference cell in the S-TAG, and when the other activated secondary cells exist in the S-TAG, setting one of the other activated secondary cells as a new downlink timing reference cell. According to the present invention, uplink transmission speed can be increased in the user equipment and user QoS can be improved by transmitting data using one or more uplink carriers in the terminal.

Abstract: To solve the above-mentioned problem, the method for transmitting and receiving a signal by user equipment (UE) through one or more cells, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, a first message indicating whether one or more cells usable by the UE are enabled; determining which cells to enable or disable on the basis of the first message; and enabling or disabling the selected cells. According to the embodiment of the present specification, by aggregating carriers amongst different base stations, a possibility for the UE to transmit and receive high-speed data through carrier aggregation can increase.
