  • Publication number: 20240137139
    Abstract: Techniques pertaining to channeling state information (CSI) pre-processing are described. A user equipment (UE) that is in wireless communication with a base station node extracts eigenvectors (EVs) from CSI acquired by the UE. The UE generates pre-processed CSI for compression by a machine-learning (ML)-based encoder of the UE into CSI feedback for the base station node by at least performing one or more of a phase discontinuity compensation (PDC), a one-step polarization separation with re-ordering, or a two-step polarization separation that includes separation based on polarization type and separation by position on the EVs.
