Title:
FEEDBACK OF CHANNEL STATE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2021/102917
Kind Code:
A1
Abstract:
Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for feedback of channel state information (CSI). In example embodiments, a first device determines a type of CSI to be fed back and then generates CSI of the type. The first device sends the generated CSI to a second device. Accordingly, if the type of CSI comprises high-precision CSI, the second device uses at least the received CSI to train a machine learning model to obtain at least a first set of parameters for generation of CSI and at least a second set of parameters for reconstruction of the CSI. The second device further sends the first set of parameters to the first device for CSI generation.
