摘要： A UE according to an embodiment of the present disclosure may receive a parameter enabling simultaneous transmission of overlapping PUCCH-PUSCH having different priorities in the same PUCCH cell group, and may perform uplink (UL) transmission related to a PUCCH and one or at least two PUSCHs overlapping the PUCCH. The one or at least two PUSCHs may include at least one of a first PUSCH on a first band to which a cell of the PUCCH belongs and a second PUSCH on a second band. The UE may perform the UL transmission without multiplexing the UCI of the PUCCH onto the second PUSCH on the basis of the first band and the second band being different from each other.

摘要： 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.
