Abstract: Disclosed is a method of transmitting/receiving a signal by a transmission device in a mobile communication system. The method includes: receiving information related to synchronization signals from a Base Station (BS); transmitting a first synchronization signal based on the received information; and receiving a second synchronization signal corresponding to the first synchronization signal based on the received information. When a UE cannot receive a synchronization signal from the BS or is located beyond a coverage of the BS, or when the BS cannot operate due to an emergency or disaster situation, UEs can configure self synchronization therebetween in a predetermined area without any assistance from the BS and thus broadcast and unicast transmission are possible between the UEs based on the synchronization.

Abstract: A control channel transmission/reception method and apparatus is provided. The base station of the present invention transmits configuration information on a control channel to a terminal, checks an aggregation level for use in transmitting the control channel, maps Demodulation Reference Signal (DMRS) to resource elements in a resource block depending on the aggregation level, determines, when the resource elements of the DMRS correspond to a first resource element set, whether to map the DMRS to resource elements corresponding to a second resource element set in the resource block, and transmits the DMRS and control channel to the terminal according to the determination result.

Abstract: Various communication techniques and related systems for a fusion between a 5th generation (5G) communication system and Internet of Things (IoT) technology are provided. A user equipment (UE) is required to select a dedicated core network so as to receive a suitable service. In a method for transmitting and receiving a signal, an enhanced Node B (eNB) of a mobile communication system transmits a first request message to a first mobile management entity (MME), receives a reroute command message based on the first request message from the first MME, and transmits a second message to a second MME based on the reroute command message. Herein, the reroute command message contains the first request message, at least one MME identifier, and a UE identifier.

Abstract: A method whereby a user equipment (UE) transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) information corresponding to downlink data received from a corresponding base station (ENB) in a long term evolution-advanced (LTE-A) system supporting carrier aggregation (CA) is provided. When physical uplink shared channel (PUSCH) transmission is not scheduled at the time of transmission of HARQ ACK/NACK information, the UE transmits HARQ ACK/NACK information via physical uplink control channel (PUCCH). When PUSCH transmission is scheduled, the UE transmits HARQ ACK/NACK information multiplexed with PUSCH to the ENB. The amount of HARQ ACK/NACK information increases in proportion to the number of aggregated carriers. The present disclosure specifies scheduling operation of the ENB and HARQ ACK/NACK mapping of the UE that maintain reception performance of HARQ ACK/NACK and PUSCH when HARQ ACK/NACK information is multiplexed with PUSCH.
