Abstract: A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

Abstract: Provided are a method for performing handover in a cellular mobile communication system that supports a carrier aggregation, and a user equipment and a node base (NodeB) using the method. A connection between the user equipment and the NodeB may be maintained and information may be exchanged using a plurality of serving carriers. Before performing the handover, the user equipment may perform measurement with respect to a neighboring NodeB supporting the carrier aggregation, and may provide parameter information to the NodeB in order to support a carrier aggregation function required for the handover. In a handover seamless environment, the continuity of a service may be provided and the performance of the service may be enhanced.

Abstract: Disclosed are operation methods of communication node supporting direct communications in network. The operation method comprises obtaining scheduling information configured for the direct communications from a first base station; identifying modulation and coding scheme (MCS) information and radio resource information included in the scheduling information; and transmitting, to a second UE, a first message to which a MCS indicated by the MCS information is applied through radio resources indicated by the radio resource information. Therefore, performance of a communication system can be enhanced.

Abstract: A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal.

Abstract: A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

Abstract: There are provided a resource allocating method for machine type communication (MTC), a data transmission and reception method for an MTC device, and an MTC device using the data transmission and reception method. The transmission and reception method for the MTC device includes: receiving a downlink frame from a base station; searching for a control information block in a downlink control resource area of the downlink frame; determining whether the control information block is for MTC service or includes control information whose destination is the MTC device, using an MTC device identifier or an identifier designated for MTC service scheduling; and extracting MTC service packet data included in a radio resource for transmission of MTC data, using the control information block, according to the results of the determination.
