On Power Constraints for 3GPP High-Resolution CSI Feedback

Multiple-input multiple-output (MIMO) precoding with non-constant modulus codebooks inherently induces perantenna local power constraints (LPCs). However, current Third Generation Partnership Project (3GPP) specifications suggest that channel state information (CSI) at the user equipment (UE) is computed under a global...

Transformer-Based CSI Prediction for 3GPP MIMO Codebooks

Accurate channel state information (CSI) acquisition is essential for multiple-input multiple-output (MIMO) systems. The Third Generation Partnership Project (3GPP) specifies a limited feedback framework in which the user equipment reports CSI to the base station. In medium-to-high mobility scenarios, CSI becomes outda...
