Discussion on AIML for CSI prediction
From Spreadtrum
Summary
Spreadtrum proposes using associated IDs to ensure consistency between training and inference for CSI prediction in AI/ML-enhanced NR air interfaces. The document contains 2 main proposals focused on leveraging existing AI-BM conclusions and configuring associated IDs within the CSI framework.
Position
Spreadtrum advocates FOR reusing existing AI-BM (beam management) conclusions and associated ID mechanisms for CSI prediction to minimize workload, and pushes AGAINST performance monitoring-based approaches (option 2) which would cause significant performance loss due to trial-and-error processes and inability to determine root causes of performance degradation.
Key proposals
- Proposal 1 (Sec 2): For CSI prediction, associated ID can be used to ensure consistency between training and inference
- Proposal 2 (Sec 2): For CSI prediction, associated ID can be configured within CSI framework
