Claim 3:
4. A synchronization signal transmission method, comprising:
detecting, by a second terminal device, at least one primary synchronization signal and at least one secondary synchronization signal, wherein the at least one primary synchronization signal and the at least one secondary synchronization signal belong to a synchronization signal block, the synchronization signal block comprises M primary synchronization signals and N secondary synchronization signals, each of the M primary synchronization signals corresponds to a particular symbol interval set in M symbol interval sets, each symbol interval set in the M symbol interval sets comprises N symbol intervals between a particular primary synchronization signal in the M primary synchronization signals and the N secondary synchronization signals, any two of the M symbol interval sets do not comprise a same symbol interval, and M and N are positive integers greater than or equal to 2, wherein each symbol interval corresponds to a unique symbol interval set in the M symbol interval sets, and wherein each symbol interval set in the M symbol interval sets corresponds to a unique primary synchronization signal in the M primary synchronization signals; and
determining, by the second terminal device, a symbol location of each of the at least one primary synchronization signal based on a symbol interval between each of the at least one primary synchronization signal and a corresponding secondary synchronization signal in the at least one secondary synchronization signal, wherein the M primary synchronization signals include only one sidelink primary synchronization signal (S-PSS) and the N secondary synchronization signals include only one sidelink secondary synchronization signal (S-SSS).
