1. A method comprising:
generating a sidelink synchronization signal block; and
sending the sidelink synchronization signal block, wherein the sidelink synchronization signal block comprises a physical sidelink broadcast channel (PSBCH), a sidelink primary synchronization signal (SPSS), and a sidelink secondary synchronization signal (SSSS), and wherein:
the PSBCH occupies M orthogonal frequency division multiplexing (OFDM) symbols of OFDM symbols occupied by the sidelink synchronization signal block in time domain, a demodulation reference signal (DMRS) occupies every OFDM symbol of the M OFDM symbols in the time domain, and the DMRS is mapped to frequency domain with an interval of n−1 subcarriers between adjacent subcarriers occupied by the PSBCH, wherein n is an integer greater than or equal to 1, M is an integer greater than or equal to 6, and the PSBCH occupies 132 subcarriers in the frequency domain; and
the SPSS occupies 2 OFDM symbols in the time domain and 127 subcarriers in the frequency domain, and the SSSS occupies 2 OFDM symbols in the time domain and 127 subcarriers in the frequency domain.
