Discussion on AI/ML for CSI prediction
From China Telecom
Summary
China Telecom discusses ensuring consistency between training and inference phases for AI/ML-based CSI prediction in 5G NR, focusing on the reuse of associated ID mechanisms from beam management. The document contains 2 proposals addressing network-side additional condition consistency and UE assumptions for CSI prediction.
Position
China Telecom advocates FOR reusing the associated ID mechanism from AI-based beam management (AI 9.1.1) for CSI prediction to ensure training/inference consistency, but recognizes that UE assumptions about the same associated ID may need different interpretations for CSI prediction compared to beam management. They support starting with associated ID within a cell before extending to multiple cells due to practical deployment challenges in aligning network-side conditions across cells.
Key proposals
- Proposal 1 (Sec 2 & Conclusions): To ensure the consistence of NW-side additional condition across training and inference for CSI prediction, associated ID introduced in AI 9.1.1 can be considered.
- Proposal 2 (Sec 2 & Conclusions): Further discuss the UE assumption on same associated ID for CSI prediction.
