1. A communication method, wherein the method comprises:
determining a first sequence whose length is Ei=0M-1Ki; and
sending the first sequence on M subcarrier groups correspondingly in M symbols, wherein
an ith subcarrier group in the M subcarrier groups comprises Ki subcarriers on a same symbol among the M symbols, i=0, 1, . . . , M−1, each of M and Ki is a natural number, M is 2 or greater, and frequency domain positions of subcarriers comprised in any two of the M subcarrier groups are different and belong to different symbols among the M symbols; and
a sequence carried in each of the M subcarrier groups is a fragment of the first sequence, and fragments of the first sequence carried in any two of the M subcarrier groups are different.
