Abstract: The present disclosure discloses a method for receiving a downlink signal by a UE in a wireless communication system. Particularly, the method may include receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH), and obtaining an indicator indicating a subcarrier spacing for the downlink channel from the PBCH, and receiving the downlink signal on the basis of the subcarrier spacing. The indicator may indicate a different subcarrier spacing according to a frequency band in which the UE operates.

Abstract: The present invention discloses a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal and a device for the same. Specifically, a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal includes: detecting a specific synchronization signal received from a base station via a first symbol of a first subframe; detecting the specific synchronization signal received from the base station via a second symbol of a second subframe; and obtaining information for the CP applied to transmission of the specific synchronization signal based on an offset value between an index of the first symbol and an index of the second symbol.
