Communication Method And Device

A communication method, comprising:

• generating, by a network device, at least one synchronization signal and physical broadcast channel (PBCH) block (SSB), wherein one of the at least one SSB comprises at least one of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), or a PBCH, the SSB occupies (N+M+X) time units, and a time-domain structure of the SSB is as follows:
• in the SSB, the PSS occupies N time units, the SSS occupies M time units, and the PBCH occupies X time units, wherein each time unit comprises Y symbols, N is an integer greater than or equal to 0, M is an integer greater than or equal to 0, X is an integer greater than or equal to 0, N, X, and M are not all 0, and Y is an integer greater than 1;
• and
• sending, by the network device, the at least one SSB.

A communication apparatus, comprising:

• a transceiver, configured to receive at least one synchronization signal and physical broadcast channel (PBCH) block (SSB), wherein one of the at least one SSB comprises at least one of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), or a PBCH, the SSB occupies (N+M+X) time units, and a time-domain structure of the SSB is as follows:
• in the SSB, the PSS occupies N time units, the SSS occupies M time units, and the PBCH occupies X time units, wherein each time unit comprises Y symbols, N is an integer greater than or equal to 0, M is an integer greater than or equal to 0, X is an integer greater than or equal to 0, N, X, and M are not all 0, and Y is an integer greater than 1;
• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform at least one of the following:
• performing synchronization;
• or
• obtaining a system message based on the received at least one SSB.
