    Abstract: The present disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond 4G communication system such as LTE. A method of transmitting a synchronization signal for device-to-device (D2D) communication in an asynchronous network is provided. The method includes transmitting, at the first cell, a system information block (SIB) including resource allocation information of a first cell and at least one neighboring cell, determining whether a first terminal is in a first mode and whether the first terminal is scheduled to perform one of a D2D communication and a D2D discovery, determining, when the first terminal is in the first mode, whether the first terminal is required to transmit a D2D synchronization signal (D2DSS), and transmitting, when the first terminal is required to transmit the D2DSS, scheduling information including a transmission time point and transmission reference timing information to the first terminal.

    Abstract: 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) are provided. The communication method and system 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 method of a user equipment (UE) for receiving data is provided. The method includes receiving, from a base station, information on radio resources allocated to the UE, and receiving, from the base station, data based on the information on the radio resources. The radio resources are associated with a plurality of symbols in a time domain and a plurality of resource block groups in a frequency domain. The information on the radio resources includes at least one of first information on a starting symbol, or second information on a size of each of the resource block groups.
