1. A reference signal sequence mapping method, comprising:
determining, by a sending device, a first multiplexing set based on a first modulation symbol set and a first reference signal sequence;
mapping the first reference signal sequence to the first multiplexing set;
determining, by the sending device, a second multiplexing set based on a second modulation symbol set and a second reference signal sequence;
mapping the second reference signal sequence to the second multiplexing set, wherein:
both the first modulation symbol set and the second modulation symbol set include at least one modulation symbol, and the first reference signal sequence and the second reference signal sequence meet orthogonally or conjugate orthogonally; and
a location of the first reference signal sequence in the first multiplexing set is the same as a location of the second reference signal sequence in the second multiplexing set, or a sum of a start index of the first reference signal sequence in the first multiplexing set and a start index of the second reference signal sequence in the second multiplexing set is equal to N, wherein:
N is an integer greater than 0; and
N is a length of the first multiplexing set, or
N is a length of the second multiplexing set; and
obtaining, by the sending device, a first single-carrier time domain symbol, a second single-carrier time domain symbol, a third single-carrier time domain symbol, and a fourth single-carrier time domain symbol based on the first multiplexing set and the second multiplexing set; and
sending the first single-carrier time domain symbol, the second single-carrier time domain symbol, the third single-carrier time domain symbol, and the fourth single-carrier time domain symbol.
