Abstract
The present disclosure provides a method for receiving a synchronization signal block by a UE in a wireless communication system. Particularly, the method includes receiving at least one SSB mapped to a plurality of symbols, wherein two regions for candidate SSBs in which the at least one SSB can be received are allocated in a specific time duration including the plurality of symbols, and a time between the two regions, a time before the two regions and a time after the two regions are identical in the specific time duration.
