Abstract
The present application provides a codebook generation method, a channel estimation method, a device, and a storage medium. The method includes: determining N angles, where the angles are spatial angles between a device and a scatterer, and N is an integer greater than 1; calculating S distances for each angle to obtain N×S distances, where the angles are spatial angles between the device and the scatterer, and S is an integer greater than 1; constructing N polar coordinate domain sub-codebooks based on the N angles and N×S distances to obtain a polar coordinate domain codebook, wherein the polar coordinate domain codebook includes the N polar coordinate domain sub-codebooks, wherein the N polar coordinate domain sub-codebooks correspond to the N angles, respectively, and each polar coordinate domain sub-codebook also corresponds to S distances associated with the corresponding angle. The present application can improve the usability of the codebook.
