Abstract
This application provides a method for obtaining channel information and a communications apparatus. The method includes: A first device sends a first reference signal to a second device, where density of the first reference signal is less than or equal to density of a second reference signal, and the second reference signal is a normal-density reference signal; the first device receives first channel state information CSI from the second device; and the first device obtains second CSI based on the first CSI and a first neural network model, where the second CSI is used to indicate channel information between the first device and the second device. The first neural network model is deployed on a side of the first device, to reduce transmission overheads of the first device and/or feedback overheads of the second device.
