New positions this meeting
- 9.1.1 — Proposes UE capability reporting with timing conditions, requires P/SP NZP-CSI-RS for rate matching, supports associated ID across multiple cells, separates CPU counting, and defines performance metrics.
- 9.1.2 — Proposes deferring second-priority cases to Rel-20, requires LMF to determine consistent sampling parameters, and supports reporting phase information from gNB to LMF.
- 9.1.3 — Proposes reusing associated ID from BM-Case 1/2. Requires support for UE-initiated data collection requests. Proposes configuring distinct observation/prediction windows for P/SP CSI reports. Focuses on Type 1/3 monitoring with SGCS/NMSE, defining fallback criteria.
