Title:
MOBILITY CLASSIFICATION AND CHANNEL STATE INFORMATION PREDICTION
Document Type and Number:
WIPO Patent Application WO/2024/029785
Kind Code:
A1
Abstract:
Methods and apparatuses for mobility classification and channel state information (CSI) prediction. A method for operating a base station includes receiving, from a user equipment (UE), a channel status state information (CSI) report comprising a precoding matrix indicator (PMI), a channel quality information (CQI), and a rank indicator (RI). The method further includes identifying a CSI configuration of the UE and performing a metric smoothing operation on the PMI. The metric smoothing operation results in a smoothed PMI. The metric smoothing operation comprises a scaling function based on the RI and a discrete Fourier transform (DFT) vector length. The method further includes determining a mobility range classification of the UE based on the smoothed PMI, other metrics in the CSI feedback report, and the CSI configuration.
