discussion
Discussion on other aspects of AI/ML model and data
From Apple
Summary
Apple discusses AI/ML model management aspects for 5G NR air interface, proposing 4 specific recommendations covering model transfer deprioritization, enhanced transfer procedures, multi-cell association IDs, and data collection standardization scope.
Position
Apple advocates for minimizing standardization scope and reducing implementation burdens by deprioritizing complex model transfer cases that require cross-vendor collaboration, while supporting flexible multi-cell operation and limiting 3GPP specifications to essential signaling aspects rather than detailed AI model implementations.
Key proposals
- Proposal 1 (Model transfer): Deprioritize model transfer Case z1 for UE-sided models in Rel-19 due to proprietary design disclosure risks, cross-vendor collaboration burden, and additional network storage requirements
- Proposal 2 (Model transfer): Add enhanced steps for model transfer z4 including network indication of model ID/meta information, UE confirmation of transfer requirement, and UE indication of model readiness for inference
- Proposal 3 (Association ID): Enable Association ID applicability for multiple cells with signaling of global cell ID lists per association ID to reduce UE data collection and training complexity
- Proposal 4 (UE side training data collection): Limit 3GPP standardization scope to only specify reference signals used for measurements, leaving AI model input design to UE implementation
