Abstract

Codebook-based precoding determination methods and apparatuses, and a device and a storage medium, which relate to the field of mobile communications. A codebook-based precoding determination method comprises: according to determined channel information corresponding to each channel status information (CSI)-RS resource, and codebook parameter information, a terminal sending CSI to a network device, wherein the CSI comprises indication information corresponding to a plurality of CSI-RS resources and indication information corresponding to each CSI-RS resource, or indication information corresponding to a plurality of port groups in one CSI-RS resource and indication information corresponding to each port group, and the CSI is used for determining precoding for the terminal on the basis of a codebook structure corresponding to the codebook parameter information.
