Abstract: A channel state information (CSI) feedback method and apparatus. A terminal device receives a channel state information reference signal (CSI-RS) from a network device, and performs channel sounding based on the CSI-RS. The terminal device feeds back CSI to the network device based on a first codebook, wherein the first codebook is determined based on one or more transmit-end space-domain and frequency-domain column vectors and one or more receive-end space-domain and time-domain column vectors that represent a channel Alternatively, the first codebook is determined based on the one or more transmit-end space-domain and frequency-domain column vectors and one or more time-domain column vectors that represent the channel.

Abstract: This application discloses a method for sending a demodulation reference signal, a method for receiving a demodulation reference signal, and a communication apparatus. The method for sending a demodulation reference signal includes: A network device generates a first signal and sends the first signal on a first time-frequency resource, where the first signal is formed by superimposing M DMRS port signals, and 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 sends more DMRS port signals on the same time-frequency resource. In this way, the network device can send more streams without increasing pilot overheads.
