A method of receiving a downlink (DL) signal by a user equipment (UE) operating on a frequency band above 6 GHz in a wireless communication system is discussed. The method includes receiving system information including first information related to one or more synchronization signal (SS) and PBCH (SS/PBCH) block groups and second information related to one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups; and receiving the DL signal in resources other than resources used for the one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups indicated by the first and second information.
