1. A communication method, applied to a terminal device, wherein the method comprises:
generating a synchronization signal, wherein the synchronization signal comprises a first sequence and a second sequence; and
sending the synchronization signal, wherein:
a first time unit carrying the first sequence is different from a second time unit carrying the second sequence;
the first sequence is a sequence obtained based on a first complex sequence and a first calculation rule, the first calculation rule comprises any one of a point multiplication rule, a conjugate point multiplication rule, and a conjugate point division rule, and the second sequence is a sequence obtained based on the first complex sequence and the first calculation rule; and
the first sequence is different from the second sequence, and a correlation processing result between the first sequence and the second sequence is a complex sequence.
