Abstract: Various examples with respect to synchronization signal block (SSB) raster shift in mobile communications are described. A processor of a user equipment (UE) performs an initial cell search to identify a cell among one or more cells of a wireless communication system. The processor then camps on the identified cell. In performing the initial cell search, the processor scans through a plurality of SSB entries for frequency bands below 3 GHz with a SSB raster spacing and a SSB raster offset frequency that support sub-carrier spacing (SCS) spaced channel raster and 100 kHz channel raster for both 15 kHz SCS and 30 kHz SCS. A minimum channel bandwidth at 5 MHz or higher for 15 kHz SCS or at 10 MHz or higher for 30 kHz SCS is supported. The SSB raster spacing is a common multiple of 15 kHz and 100 kHz. The SSB raster offset frequency for 100 kHz channel raster is a multiple of 30 kHz plus/minus 10 kHz.
