WIRELESS COMMUNICATION METHOD AND APPARATUS

This application provides a wireless communication method and apparatus, and may be applied to the field of autonomous driving, intelligent driving, or short-range communication. The wireless communication method includes: mapping a first reference signal to preamble information, where the preamble information sequentially includes a first synchronization sequence group part, a first part, a second synchronization sequence group part, and a second part in time domain, a length of the first part in time domain is fixed, the first synchronization sequence group part, the first part, the second synchronization sequence group part, and the second part each include at least one orthogonal frequency division multiplexing OFDM symbol, and the first reference signal is mapped to K subcarriers in subcarriers corresponding to at least one OFDM symbol included in the first part and/or the second part, where K is a positive integer; and sending the preamble information. In a low signal-to-noise ratio scenario, sufficient synchronization precision is obtained and data transmission between a master node and a slave node is further implemented according to the method.
