20. A terminal, comprising:
-
a memory; and a processor that is connected to the memory and that performs D2D communication, wherein the processor generates a first synchronization signal for D2D synchronization using a second OFDM symbol with a smaller length than that of a first Orthogonal Frequency Division Multiplexing (OFDM) symbol used in a Long Term Evolution (LTE) system, and transmits the first synchronization signal through a first area of a first frame, and the first frame comprises the first area and a second area for transmitting/receiving a Physical D2D Broadcasting Channel (PD2DBCH).
