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: The present invention relates to a method and an apparatus for a user equipment receiving MBMS service processing a semi-permanent scheduling from an MBSFN subframe. A method for a user equipment receiving the multimedia broadcast multicast service (MBMS) processing a downlink scheduling in a mobile communication system of the present invention comprises: a detection step of detecting the occurrence of the downlink scheduling in a random transmission time interval; a decision step of deciding whether to process the downlink scheduling, depending on whether the user equipment is set to a transmission mode 9 or whether the transmission time interval belongs to a multimedia broadcast multicast service single frequency network (MBSFN) subframe; and a processing step of processing or disregarding the downlink scheduling based on the result of the decision.

Abstract: The present invention pertains to a method and device for preserving mobility information in terminal state transition and effectively re-accessing in a heterogeneous cell network in a mobile communication system. A method for estimating a mobility state of a terminal in a mobile communication system according to one embodiment of the present invention may comprise the steps of: receiving, by the terminal, system information from a serving cell during an idle state; calculating mobility state information by using the received system information; storing the mobility state information; and transmitting the mobility state information to a base station when the terminal is connected to the base station. According to one embodiment of the present invention, when an idle state of a terminal is changed to a connection state in a mobile communication system, a mobility state of the terminal can be more effectively estimated.
