FUTUREWEI · 9.1.1

Futurewei proposes reusing the existing CSI framework extensively to reduce specification effort for Rel-19 AI/ML-based beam management. They oppose supporting Opt 3 and Opt 4 for UE-sided model inference reports, arguing that defining probability and confidence metrics is difficult and offers unclear benefits. They require the maximum number of reported beams (M) for network-sided models to be increased from 4 to 8 as a starting point. They support using RS ID as an implicit beam ID indicator and prefer Option B for RSRP reporting, which prioritizes measured L1-RSRP over predicted values when measurements are available. They confirm the working assumption that the associated ID can be configured within the CSI framework to ensure consistency across training and inference.

FUTUREWEI advocates FOR maximizing reuse of existing CSI framework to minimize specification effort, supporting simpler approaches that avoid complex new metrics like probability and confidence information. They push AGAINST supporting multiple alternatives that would increase complexity, specifically opposing Opt 3/4 for inference reporting and other performance monitoring alternatives beyond Alt 1. They favor practical solutions like using RS ID as implicit beam ID rather than defining new beam identifiers.
