1. A data transmission method, comprising:
obtaining a first sequence and a common sequence group, wherein a quantity of sequences in the common sequence group is N;
the first sequence comprises K first sub-sequences, and lengths of the K first sub-sequences are sequentially B1, B2, . . . , and BK, wherein K is a positive integer, B1=log2N, and a length B1 of a 1st first sub-sequence is greater than or equal to a length of another first sub-sequence in K first sub-sequences;
separately mapping the K first sub-sequences into K second sub-sequences based on the common sequence group; and
outputting a second sequence, wherein the second sequence comprises the K second sub-sequences.
