Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.
