Abstract: Disclosed herein is a method for receiving remaining minimum system information (RMSI) by a user equipment (UE) in a wireless communication system. The method includes receiving an synchronization signal (SS)/physical broadcast channel (PBCH) block including an SS and a PBCH in a half-frame, obtaining, via the PBCH, information related to a monitoring window for receiving a physical downlink control channel (PDCCH) for the RMSI, receiving the PDCCH within the monitoring window, and receiving the RMSI based on the PDCCH, wherein monitoring windows related to SS/PBCH blocks having consecutive indexes among SS/PBCH blocks receivable in the half-frame are at least partially overlapped each other.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band and provides methods for performing a channel access process for transmitting different types of signals, and devices supporting the same. According to one embodiment of the present invention, a method for transmitting different types of signals in a wireless access system supporting an unlicensed band can comprise the steps of: performing a first channel process (CAP) for transmitting a first type of signal; and transmitting a transmission burst including the first type of signal through the unlicensed band if it is determined that a serving cell (SCell) of the unlicensed band is in an idle state after performing the first CAP. At this time, at least one of first parameters for performing the first CAP can be set to be value less than that of second parameters for performing a second CAP for transmitting a second type of signal.

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: Provided are a method and an apparatus for competition-based transmitting of uplink data in a wireless communication system to which a non-orthogonal multiple access scheme is applied. Particularly, a UE receives, from a base station, information relating to a contention zone. The information relating to the contention zone includes predefined contention zone patterns and predefined terminal classes. The terminal selects a terminal class for the terminal from among the predefined terminal classes. The terminal selects a contention zone pattern for the terminal from among the predefined contention zone patterns on the basis of the selected terminal class. The uplink data is transmitted to the base station through a plurality of contention zones included in the selected contention zone pattern.
