Discussion on AI/ML model based CSI prediction

From Xiaomi
Status: not treated

Summary

Xiaomi proposes methods to ensure consistency between AI/ML model training and inference for UE-side CSI prediction, presenting simulation results showing that models trained with consistent TXRU mapping configurations achieve significantly better performance. The document contains 2 proposals and 1 observation focused on network-side condition indication and leveraging beam prediction methods.

Position

Xiaomi advocates FOR explicit network indication of additional conditions (like TXRU mapping) to UEs to maintain AI/ML model performance consistency, and FOR leveraging beam prediction consistency methods as a foundation for CSI prediction. They push FOR high-priority study of network-side condition information provision and performance monitoring options, demonstrating through simulation that mixed training datasets significantly degrade performance compared to consistent configurations.
