Discussion on AI/ML for CSI prediction

      Position extracted by Claude
    

CMCC proposes studying two options for ensuring consistency of NW-side additional conditions across training and inference for AI-based CSI prediction: one based on associated ID and another based on performance monitoring. They propose combining these solutions, where the associated ID preliminarily guarantees consistency without exposing proprietary information, while performance monitoring handles residual issues. CMCC requires that if associated ID is supported, the UE assumes consistency of NW-side additional conditions with the same ID at least within a cell, and that the ID is configured within the CSI framework. For performance monitoring, they propose using intermediate KPIs as a starting point for Type 3 monitoring and present two alternatives for Type 1 monitoring involving UE-calculated metrics or UE-recommended LCM decisions. Finally, CMCC proposes reusing data collection mechanisms from AI/ML beam management and adapting Rel-18 CSI parameters, such as measurement and reporting windows, for AI/ML-enabled CSI prediction.

      Summary
    

CMCC discusses specification impacts for AI/ML-based CSI prediction in Rel-19, focusing on ensuring consistency between training and inference phases. The document presents 8 proposals covering consistency mechanisms via associated IDs and performance monitoring, data collection reuse from beam management, and adaptation of Rel-18 CSI parameters.
