Abstract: Provided is a method for performing uplink data compression (UDC) by a user equipment (UE). The method includes receiving configuration information on UDC; generating a first UDC packet by compressing uplink data, based on the configuration information on UDC; transmitting the first UDC packet; receiving, from the base station, packet data convergence protocol (PDCP) layer control information including checksum error information about whether a checksum error has occurred in the first UDC packet; and resetting a UDC buffer used in compressing the uplink data, based on the PDCP layer control 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 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 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: A device and method for handling HARQ feedback in a mobile communication system are disclosed. The HARQ feedback handling method includes: analyzing a control message from a base station to recognize presence of HARQ feedback relationships between downlink carriers and uplink carriers; determining an uplink carrier (a downlink carrier) to support HARQ feedback in response to downlink traffic (uplink traffic) sent through a downlink carrier (an uplink carrier); and sending (receiving) HARQ feedback through the determined uplink carrier (downlink carrier).
