1. A reference signal indication method, comprising:
receiving a plurality of reference signals;
sending at least one codeword on a first time-frequency resource, wherein the at least one codeword comprises a first codeword, the first codeword corresponds to a first reference signal in N reference signals of the plurality of reference signals, the first reference signal is a selected reference signal, the N reference signals are a subset of the plurality of reference signals, and N is a positive integer; and
determining, based on the N reference signals of the plurality of reference signals and M corresponding codewords, the first codeword corresponding to the first reference signal, wherein the M codewords are a subset of codewords associated with the first time-frequency resource, and M is a positive integer;
wherein the N reference signals of the plurality of reference signals are each of candidate reference signals of a cell,
the N reference signals of the plurality of reference signals are reference signals sent in the cell,
the N reference signals of the plurality of reference signals are a subset of each of the candidate reference signals of the cell, or
the N reference signals of the plurality of reference signals are a subset of the reference signals sent in the cell.
