    Abstract: A method for allowing terminals to exchange discovery or synchronization signals to determine their presences among each other within a service area of a base station is provided. The method includes collecting multicast identifiers of another terminal for use in multicast communication, receiving a multicast control channel for Device-to-Device (D2D) multicast communication, performing Cyclic Redundancy Check (CRC) on the received multicast control channel using the collected multicast identifiers, and receiving, when the CRC is successful, the D2D multicast according to the multicast control channel. The D2D communication method and apparatus is advantageous in that the D2D terminal is capable of transmitting the discovery or synchronization signal to discover the neighbor terminals without disturbing downlink or uplink communication between the base station and the terminal, wherein the base station configures the resource for D2D communication so as to support D2D communication without an inter-device interference.

    Abstract: A method and apparatus for transmitting and receiving a signal using a channel output feedback in a wireless communication system and Hybrid-Automatic Repeat Request (ARQ) are provided. The method and apparatus include a transmitter configured to transmit to a base station and a first packet on a precoder received from the base station. A receiver configured to receive, from the base station, a Channel Output Feedback (COF) of the transmitted first packet and information for transmitting a second packet. A controller configured to prepare a variant of the second packet using the COF and the received information for transmitting the second packet, and to control to transmit the prepared variant to the base station.

    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: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and an apparatus for transmitting a reference signal, the method of a terminal according to the present invention comprising: receiving, through a higher layer signaling, configuration information including first information indicating one of a first demodulation reference signal (DMRS)-related table and a second DMRS-related table; receiving control information including second information on DMRS information; analyzing, based on the second information, a DMRS-related table indicated by the first information; and receiving a DMRS based on the result of the analysis.
