    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate in comparison to the 4G communication system, such as long term evolution (LTE). A method for a terminal to establish synchronization with another terminal in a network supporting device-to-device (D2D) communication is provided. The method includes scanning, at the terminal, for synchronization signals from at least one base station, acquiring, when a synchronization signal is received from a base station, synchronization with the base station based on the synchronization signal, measuring power of the synchronization signal received from the base station, and transmitting, when data to be transmitted are generated in idle mode and the received signal power is less than a received signal power, a synchronization signal as a synchronization relaying 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) is provided. 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 method for obtaining numerology information by a user equipment (UE) includes detecting synchronization signals, obtaining first numerology information for the synchronization signals, decoding a physical broadcast channel (PBCH) based on the first numerology information, obtaining second numerology information for a physical downlink control channel (PDCCH) according to a result of the decoding, and receiving control information on the PDCCH based on the second numerology information.

    Abstract: The present disclosure relates to a pre-fifth generation (5G) or 5G communication system to be provided for supporting higher data rates beyond fourth generation (4G) communication system such as long term evolution (LTE).
    A synchronization signal transmission/reception method for use in a device-to-device (D2D) communication system is provided. A method of transmitting a synchronization signal for D2D communication in an asynchronous network, in which a first terminal located in a first cell controls synchronization with a second terminal located outside of the first cell, includes transmitting, at the first cell, a system information block (SIB) including resource allocation information of the first cell and at least one neighboring cell, determining whether the 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.
