This application discloses a method for sending a demodulation reference signal. In the method, a network device generates a first signal and sends the first signal on a first time-frequency resource. The first signal is formed by superimposing M DMRS port signals, and the delay segmentation locations corresponding to at least two of the M DMRS port signals are different.
