Abstract: The present invention discloses 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 COPRESET 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.
