Title:
TWO-STAGE LINEAR COMBINATION CHANNEL STATE INFORMATION FEEDBACK
Document Type and Number:
WIPO Patent Application WO/2024/022328
Kind Code:
A1
Abstract:
A UE obtains a phase rotation matrix that transforms an original channel state information matrix into a rotated channel state information matrix. The UE determines the original channel state information matrix based on measurements of reference signals transmitted by a base station. The UE applies the phase rotation matrix to the original channel state information matrix to generate the rotated channel state information matrix. The UE determines a first set of coefficients that is to be applied to a Discrete Fourier Transform (DFT) basis matrix to obtain the rotated channel state information matrix. The UE reports a second set of coefficients derived from the first set of coefficients to the base station.
