INFORMATION OBTAINING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2019/157709

A1

The present application provides an information obtaining method and apparatus, a device, and a storage medium. The method comprises: performing inverse discrete Fourier transform (IDFT) on frequency domain channel information to obtain time domain channel information; performing two-stage amplitude quantization and phase quantization on the time domain channel information to obtain channel state information; and sending the channel state information to a network device. By means of the transform from a frequency domain to a time domain, a terminal side enables channel state information to be sparser, such that the channel state information feedback amount can be reduced. In addition, two-stage amplitude quantization can improve the accuracy of channel feedback on the basis of increasing a little feedback amount.
