Abstract
The present disclosure provides a method for receiving a synchronization signal/physical broadcast channel (SS/PBCH) block by a terminal in an unlicensed band. Particularly, the method may comprise: receiving an SS/PBCH block including an SS and a PBCH; detecting an index of a demodulation reference signal (DMRS) sequence for the PBCH; and on the basis of the index of the DRMS sequence, acquiring information relating to a time when an index of the SS/PBCH block and the SS/PBCH block are received, wherein the number of indices of the SS/PBCH block is smaller than or equal to the number of indices of the DMRS sequence, and the indices of the SS/PBCH block are cyclically mapped to the indices of the DMRS sequence.
