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.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE receives a message having Demodulation Reference Signal (DMRS) switching bits that indicate which DMRS pattern is being used of either of a first DMRS pattern or a second DMRS pattern. The UE determines the DMRS pattern being used from the DMRS switching bits. The UE applies the determined DMRS pattern being used to processing of uplink and downlink channels.
