Method and apparatus for transmitting data using a multi-carrier in a mobile communication system
First Claim
1. A method for performing discontinuous reception (DRX) by a terminal in a communication system, the method comprising:
- receiving, from a base station, DRX related information including a timer value related to on-duration, a first DRX cycle value and a second DRX cycle value;
receiving, from the base station, control information with a zero bit payload, the control information including a logical channel ID (LCID), the LCID identifying a type of the control information;
identifying the type of the control information based on the LCID;
configuring a first DRX with the first DRX cycle value if the control information is information related to the first DRX; and
configuring a second DRX with the second DRX cycle value if the control information is information related to the second DRX,wherein the first DRX and the second DRX are configured with the timer value related to on-duration included in the DRX related information.

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.
