Title: METHOD FOR TRANSMITTING OR RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM SUPPORTING D2D COMMUNICATION AND APPARATUS FOR PERFORMING SAME
Abstract:
A method for receiving a signal through a physical format adaptable to a wireless communication environment by a device supporting D2D communication according to an embodiment of the present invention comprises the steps of: receiving a synchronization signal from a transmission node on the basis of one of a first physical format and a second physical format; and performing synchronization with the transmission node on the basis of the synchronization signal, wherein when the second physical format is used, M synchronization symbols in addition to N synchronization symbols used in the first physical format are set in the same sub-frame, and a total of (N + M) synchronization symbols included in the same sub-frame may include a first synchronization symbol to which a first Zadoff-Chu sequence generated through first root indexes is mapped, and a second synchronization symbol to which a second Zadoff-Chu sequence generated through second root indexes is mapped.
