    Abstract: The present invention relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate than that of a 4G system and subsequent systems, and a system thereof. The present invention can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety related services and the like). The present invention provides a method and a device for transmitting a synchronization signal for device-to-device (D2D) communication. According to the present invention, a first terminal receives a D2D synchronization signal (D2DSS) and a physical D2D synchronization channel (PD2DSCH) corresponding to the D2DSS from a second terminal, and transmits the D2DSS to the second terminal according to a method preassigned with the second terminal so as to indicate that the first terminal has successfully received the D2DSS or the PD2DSCH.

    Abstract: An apparatus performs a method for generating information indicating channel quality when a dynamic range of a receive signal strength and an interference signal strength is considerable in a wireless communication system using beamforming. A base station (BS) for processing feedback information for scheduling receives from a mobile station (MS) first feedback information comprising a receive signal strength measurement result in paths selected from a plurality of downlink paths between the BSs and the MS, designates a transmit (TX) resource for interference measurement of the MS based on the first feedback information, receives from the MS second feedback information comprising an interference measurement result in the designated TX resource region, and calculates a Signal to Interference plus Noise Ratio (SINR) of the MS based on the first feedback information and the second feedback information. The designated TX resource includes a resource other than a signal TX resource for the MS.
