Abstract: A method and apparatus for transmitting a physical random access channel (PRACH) in a wireless communication system is provided. A user equipment (UE) receives multiple PRACH configurations which include a first PRACH configuration for new radio access technology (NR) downlink/uplink (DL/UL) carrier in a NR band and a second PRACH configuration for a supplemental UL carrier in a long-term evolution (LTE) band, and transmits at least one of a first PRACH for accessing the NR DL/UL carrier in the NL band by using a first PRACH power based on the first PRACH configuration, or a second PRACH for accessing the supplemental UL carrier in the LTE band by using a second PRACH power based on the second PRACH configuration. The first PRACH configuration and the second PRACH configuration include different PRACH power configurations.

Abstract: The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.

Abstract: A method by which a terminal transmits an uplink signal in an unlicensed band, and an apparatus using same are provided. The method receives, from a base station, channel occupancy information through a PDCCH and transmits the uplink signal to the base station through a configured grant uplink access (CUL) type physical uplink shared channel (PUSCH) on the basis of the channel occupancy information. The channel occupancy information indicates which sub-band of a CUL band including a plurality of sub-bands enables the terminal to transmit the CUL type PUSCH within a channel occupancy time (COT) acquired by the base station through a channel access procedure.
