9.1.2 shifted

Google shifted their focus from general flexible channel measurements to specifically proposing the extension of enhanced path-based measurement to the UE side to reduce reporting overhead. They added a new proposal to report L1-SINR alongside path-based measurements to enable network filtering. For model performance monitoring in Case 1, they refined their support for UE-side monitoring (Option A) by specifying a simple 1-bit failure indication and explicitly opposing Option B due to functional redundancy and privacy concerns. They also added support for Alternative 4, requiring explicit provision of TRP geographical coordinates from the LMF.

9.1.3 shifted

Google shifted from proposing specific associated ID management to supporting the reuse of the broader Beam Management inference and monitoring frameworks. They added a new specific metric proposal: CQI offset between predicted and ground-truth CSI. They refined their resource configuration proposal by specifying separate CSI-RS resource sets for inference and monitoring. They also added a preference for NW-triggered reports via UCI while deprioritizing event-triggered reports.
