Abstract: This application discloses a channel state information feedback method and a communication apparatus. The method includes: determining channel state information based on a first codebook, and sending the channel state information. The first codebook is determined based on a channel represented by one or more spatial-frequency domain column vectors, and the one or more spatial-frequency domain column vectors indicate the channel in joint spatial-frequency domain. In this solution, the first codebook may be determined based on the channel represented by the one or more spatial-frequency domain column vectors. Because the one or more spatial-frequency domain column vectors may represent the channel in joint spatial-frequency domain, that is, the first codebook represents the channel based on joint spatial-frequency domain, a joint spatial-frequency domain feature may be fully used, to explore a sparse feature of the channel, thereby improving system performance.

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.
