Title:

SYSTEMS, APPARATUSES, AND METHODS USING CHANNEL STATE INFORMATION (CSI) NORMALIZATION AND QUANTIZATION

Document Type and Number:

WIPO Patent Application WO/2024/022363

Kind Code:

A1

Abstract:

A computerized method performed by a first apparatus. The method has the steps of: normalizing real and imaginary parts of parameters of a channel between the first apparatus and a second apparatus to a first bit-size, and quantizing the normalized real and imaginary parts of the parameters to obtain channel state information (CSI) coefficients of a second bit-size for feeding back to the second apparatus.
