    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 sturcture 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 is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

    Abstract: Methods for preventing address collisions in device-to-device (D2D) communications are disclosed. An operation method of a first terminal in a wireless communication network may comprise configuring an internet protocol (IP) address of the first terminal used for D2D communications; generating an announcement frame based on an address resolution protocol (ARP) including the IP address; and transmitting the announcement frame. Thus, a problem of collisions between IP addresses in D2D communications can be resolved.

    Abstract: A first terminal within a first cell of a first base station receives a synchronization signal and a synchronization channel that are broadcasted through a downlink by the first base station. The first terminal acquires synchronization for D2D communication using the synchronization signal and the synchronization channel. When the first terminal is connected to the first base station, in order to request allocation of a first resource for D2D communication, the first terminal transmits first information for D2D communication to the first base station through a first data channel for cellular communication. The first terminal receives D2D control information including information about the first resource that is allocated to the first terminal from the first base station. The first terminal broadcasts a second data channel for D2D communication using the D2D control information.
