Abstract: The present disclosure provides a method of transmitting a Physical Broadcasting Channel (PBCH) by a base station in a wireless communication system. Particularly, the method may include generating a PBCH payload including bits indicating a frame in which the PBCH is transmitted; scrambling at least some of the bits included in the PBCH payload using second and third least significant bits among the bits; and transmitting the bits of the PBCH payload including the at least some scrambled bits to a user equipment.

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: A method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the CORESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.

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 method and device for transmitting a transport block in a wireless communication system is provided. Particularly, a terminal receives, from a base station, information on the number of subcarriers in a partial band included in an allocated carrier. The terminal distributes a soft buffer possessed by the terminal in proportion to the number of subcarriers in the partial band. The terminal determines a transport block size for each partial band according to the size of the distributed soft buffer. The terminal transmits, to the base station, the transport block within the transport block size.
