[DRAFT] Reply LS on applicable functionality reporting for beam management UE-sided model
From Samsung
Summary
This is a liaison statement from RAN1 to RAN2 responding to questions about beam management UE-sided AI/ML model functionality reporting. The document provides answers to 9 detailed questions and includes 2 agreements and 1 conclusion about the configuration and activation procedures for AI/ML-enabled beam management features.
Position
Samsung/RAN1 advocates for a flexible AI/ML functionality reporting framework that supports both CSI-ReportConfig-based inference configuration and separate inference parameter sets for applicability reporting. They push for optional network-side additional conditions and support associated ID mechanisms while maintaining that activation timing and mandatory/optional status of various parameters remain under discussion.
Key proposals
- Agreement 1: In Step 3, network provides configurations to UE including CSI-ReportConfig for inference configuration and/or sets of inference related parameters for applicability reporting only
- Agreement 1: UE is allowed to do UAI (UE AI) reporting via OtherConfig with applicability report based on CSI-ReportConfig and/or inference related parameters
- Agreement 1: CSI report configuration for UE-side model inference cannot be activated immediately upon receiving Step 3
- Agreement 1: In Step 4, UE reports applicability for all configured CSI-ReportConfigs and/or sets of inference related parameters
- Agreement 1: Applicable periodic CSI Report is considered activated only if applicability is reported in RRCReconfigurationComplete
- Agreement 1: Step 5 network configuration is optional if UE already has CSI-ReportConfig from Step 3
- Agreement 2: Multiple CSI reports for inference for UE-side beam management model can be configured/activated/triggered, subject to UE capability
- Conclusion: For Step 5 CSI-ReportConfig, periodic CSI Report is activated after RRCReconfigurationComplete while aperiodic/semi-persistent can be activated/triggered by network
- Answer to Q1: UE reports UE-capability information for Rel-19 AI/ML-enabled Features/FGs including components and value ranges
- Answer to Q2: RAN1 supports associated ID to ensure consistency of network-side additional condition across training and inference for BM-Case 1 and 2
