Synchronization raster design method and apparatus

A communication apparatus, comprising:

• a memory configured to store program instructions and data;
• and a processor coupled to the memory and configured to execute the instructions in the memory to:
• determine a first bandwidth, wherein a frequency range corresponding to the first bandwidth is above 52.6 gigahertz (GHz), and
• send a synchronization signal block (SSB) at a frequency domain location of a synchronization raster corresponding to a global synchronization number in the frequency range.
