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. Because the first signal is formed by superposing the M DMRS port signals, that is, the network device sends a plurality of DMRS port signals on a same time-frequency resource, reference signal overheads can be reduced. The network device can send more DMRS port signals using the same amount time-frequency resources. In this way, the network device can send more streams without increasing signaling overheads.
