Discussion on AI/ML for Beam Management

      Position extracted by Claude
    

Quectel proposes extending UE capability for RS measurement beyond 64 RS per resource set to support larger Set A configurations, utilizing bitmaps for Set B pattern selection. They support configuring two resource sets for Set A and Set B separately within a single CSI-ResourceConfigId for inference reporting. For BM-Case2, Quectel proposes supporting Aperiodic (AP) CSI-RS and including time-based predictions with confidence levels in the inference report. They argue for a unified mechanism for measurement reporting, data collection, and monitoring to ensure consistent performance evaluation. Additionally, they propose that the network must be notified of performance degradation in UE-sided monitoring to maintain synchronized management during model transitions.

      Summary
    

Quectel presents 15 proposals regarding AI/ML-based beam management in NR, focusing on data collection frameworks for network and UE-side models, inference reporting configurations, and performance monitoring mechanisms. The document addresses specification impacts for Beam Management Case 1 (BM-Case1) and Case 2 (BM-Case2), proposing enhancements to CSI-ReportConfig structures, support for aperiodic CSI-RS, and unified monitoring metrics to ensure model accuracy and reduce overhead.
