Synchronization signal transmission method, network device, and terminal device

A synchronization signal transmission method, comprising:

• receiving, by a terminal device, m synchronization signal blocks sent by a network device;
• and
• determining, by the terminal device, a time domain position of a synchronization signal block in the synchronization signal blocks based on information about the synchronization signal block, wherein
• the time domain position of the synchronization signal block is one of {s1, s2, . . . , sm}+n×T, s1 represents a start symbol index of the first synchronization signal block in a time unit, s2 represents a start symbol index of the second synchronization signal block in the time unit, sm represents a start symbol index of an mth synchronization signal block in the time unit, the time unit comprises T symbols, m is an integer in [1, T], T is any one of 12, 24, 36, 48, 60, 72, 84, and 96, n represents an index of the time unit, and a value of n is an integer in [0, 157].

A terminal device, comprising:

• a receiver, configured to receive m synchronization signal blocks sent by a network device;
• and
• a processor, configured to determine a time domain position of a synchronization signal block in the synchronization signal blocks based on information about the synchronization signal block, wherein
• the time domain position of the synchronization signal block is one of {s1, s2, . . . , sm}+n×T, s1 represents a start symbol index of the first synchronization signal block in a time unit, s2 represents a start symbol index of the second synchronization signal block in the time unit, sm represents a start symbol index of an mth synchronization signal block in the time unit, the time unit comprises T symbols, m is an integer in [1, T], T is any one of 12, 24, 36, 48, 60, 72, 84, and 96, n represents an index of the time unit, and a value of n is an integer in [0, 157].
