Abstract: A method and an apparatus for beam failure recovery in a communication system. The method for beam failure recovery includes the steps of: searching for a plurality of candidate beams when a beam failure is detected; transmitting a beam failure recovery request signal to a base station by using beam #1 of the plurality of candidate beams; receiving a beam failure recovery response signal in response to the beam failure recovery request signal via beam #1 from the base station; and transmitting an SR requesting a resource for transmission of multi-beam setting information to the base station, where the multi-beam setting information includes indexes of one or more beams excluding beam #1 of the plurality of candidate beams.

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: 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: A random access (RA) procedure based state transition method in a communication system is disclosed. A terminal in the communication system may comprise transmitting a RA preamble to a base station when an uplink data unit to be transmitted exists in the terminal; receiving a RA response from the base station in response to the RA preamble; and transmitting a message including the uplink data unit to the base station through a resource indicated by the RA response. Therefore, performance of the communication system can 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: Provided is a method of transmitting and receiving data using a persistent allocation scheme in order to effectively support a voice service between a base station and a mobile terminal in a packet based mobile communication system. When an error occurs in transmitting control information that indicates whether to use a radio resource using the persistent allocation scheme, the base station may retransmit the control information and thereby maintain a communication quality.
