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 disclosure includes the steps of 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 disclosure, 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. ## Claims ### Claim 1 A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station via a radio resource control (RRC) signaling, discontinuous reception (DRX) related information including a timer value related to an on-duration, a long DRX cycle value and a short DRX cycle value;
