Synchronization signal block transmission method and communications apparatus

A communications apparatus comprising:

• at least one processor;
• and
• a communications interface, wherein,
• the at least one processor is configured to receive a synchronization signal block (SSB) from a network device in a resource position of the SSB by the communications interface, wherein the resource position of the SSB is comprised in a candidate resource position set of the SSB, and the SSB comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), wherein,
• one resource position in the candidate resource position set is mapped to one symbol in time domain, the PSS, the SSS, and the PBCH are frequency-division multiplexed in the resource position, and a subcarrier spacing corresponding to the resource position is 15 kHz, 30 kHz, or 60 kHz.
