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: A default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.

Abstract: Disclosed herein is a method for transmitting a physical random access channel (PRACH) by a user equipment in a wireless communication system. In particular, the method includes receiving information about PRACH resource allocation, and transmitting, based on the information, the PRACH on any one of one or more PRACH occasions allocated in a PRACH slot, wherein a number of the one or more PRACH occasions is based on a preamble format and a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol for the PRACH.

Abstract: A UE transmits a random access channel (RACH) preamble and a BS receives the RACH channel. The BS configures the RACH preamble to align boundaries of the RACH preamble with boundaries of OFDM symbols on which the RACH preamble is configured in the time domain. The UE generates/transmits the RACH preamble to align the boundaries of the RACH preamble with the boundaries of OFDM symbols on which the RACH preamble is configured in the time domain.
