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.

Abstract: A method and apparatus is configured to control a discontinuous reception (DRX) in a mobile communication system. The method includes: interrupting the DRX operation when a radio resource control (RRC) connection reestablishment procedure is initiated; transmitting an RRC connection reestablishment request message from the user equipment to an evolved node B (ENB); receiving an RRC connection reestablishment message from the ENB to the user equipment; and resuming, if the received RRC connection reestablishment message contains new DRX setting information, the interrupted DRX operation according to the new DRX setting information. The DRX operation can be interrupted or resumed at a proper time point when an RRC connection is reestablished or reconfigured or a handover is performed, thereby reducing power consumption in the user equipment.

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: Methods for performing a random access procedure by a terminal and a base station in a wireless communication system, a terminal, and a base station are provided. The method for performing a random access procedure by a terminal in a wireless communication system includes selecting a physical random access channel (PRACH) resource from one or more PRACH resources; transmitting, to a base station, a random access preamble based on the selected PRACH resource; identifying a random access radio network temporary identifier (RA-RNTI) based on information associated with the selected PRACH resource, wherein the information includes identity information for an uplink used for the random access preamble transmission; and monitoring a control channel for a random access response (RAR) based on the RA-RNTI.

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.
