Abstract: A method for a transmission-side device to transmit a signal in a wireless communication system is disclosed. To this end, the transmission-side device forms a multiplexed block by multiplexing a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH) signal in time and frequency domains, wherein the PSS and the SSS form a synchronization signal (SS) by being multiplexed by the time-division multiplexing (TDM) method, and the SS and PBCH signals form the multiplexed block by being multiplexed by the TDM or frequency-division multiplexing (FDM) method.

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: According to the present invention, a downlink control channel can be transmitted in varied numbers of OFDM symbols. The downlink control channel can be transmitted in a first number of OFDM symbols or can be transmitted in a second number of OFDM symbols. A user equipment can monitor a first downlink control channel candidate that spans the first number of OFDM symbols and can monitor a second downlink control channel candidate that spans the second number of OFDM symbols in a transmission time interval (TTI) for the reception of the downlink control channel. The downlink control channel can be transmitted by means of one or more control channel elements (CCE), each CCE comprising resources in the same OFDM symbol.
