METHOD FOR TRANSMITTING D2D SYNCHRONIZATION SIGNAL AND TERMINAL THEREFOR

摘要

Disclosed is a method for transmitting a synchronization signal of device-to-device (D2D) communication. The method for transmitting a D2D synchronization signal of the present application may indicate the state of a terminal, the purpose of transmission of a primary D2D synchronization signal (PD2DSS), or whether to transmit a physical D2D shared channel (PD2DSCH), on the basis of an order in which root indexes of PD2DSSs are transmitted or the value of a root index used by a PD2DSS.
