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. A wireless device for receiving signals, a base station for transmitting a master information block (MIB) in a wireless communication network and a method therefore are provided. The wireless device comprises a receiver configured to receive, from a base station, a master information block (MIB) for a first communication using a first frequency bandwidth, and a processor configured to identify a frequency offset between a center frequency of the first frequency bandwidth and a channel raster for a second communication using a second frequency bandwidth based on information in the MIB. The receiver is further configured to receive, from the base station, signals, through the first communication, based on the frequency offset. The first frequency bandwidth is narrower than the second frequency bandwidth.

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.
