A UE in a wireless communication system is provided. The UE comprises a transceiver configured to receive, from a BS, a SS/PBCH block including the PBCH using a first frequency location (GSCN-Current) over downlink channels, GSCN-Current being based on a set of predefined synchronization rasters that is determined by a global synchronization channel number (GSCN). The UE further comprises a processor operably connected to the transceiver, the processor configured to determine the SS/PBCH block, identify content of a PBCH included in the determined SS/PBCH block, determine a configuration for at least one of the SS/PBCH block that is associated with a PDCCH including scheduling information for RMSI on the GSCN-Current or the SS/PBCH block that is not associated with the PDCCH including the scheduling information for the RMSI on the GSCN-Current.
