Title:
SYNCHRONIZATION SIGNAL BLOCK RASTER SHIFT IN MOBILE COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2019/161767
Kind Code:
A1
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 3GHz with a SSB raster spacing and a SSB raster offset frequency that support sub-carrier spacing (SCS) spaced channel raster and 100kHz channel raster for both 15kHz SCS and 30kHz SCS. A minimum channel bandwidth at 5MHz or higher for 15kHz SCS or at 10MHz or higher for 30kHz SCS is supported. The SSB raster spacing is a common multiple of 15kHz and 100kHz. The SSB raster offset frequency for 100kHz channel raster is a multiple of 30kHz plus/minus 10kHz.
