Huawei · 9.1.1

Huawei proposes studying mechanisms to support beam sets exceeding 64 resources, either through multiple legacy sets or a single set up to 256 resources. They require the associated ID for UE-side models to be limited to a cell-specific manner to avoid proprietary disclosure and NW burden, and propose applying the ID to a pair of Set A and Set B. Huawei opposes extending Rel-17 TCI state activation for BM-Case 2 future time instances, citing insignificant overhead savings and substantial implementation complexity. They propose reusing existing TCI state timelines for predicted beams and support reporting more than 4 predicted beams (K>4) for UE-side inference. For monitoring, they prefer dedicated CSI report configurations (Option 2) to separate inference and monitoring processes, and propose defining CPU/memory requirements per AI/ML functionality.

Huawei advocates FOR pragmatic reuse of existing CSI framework and signaling mechanisms while pushing AGAINST overly complex new procedures. They strongly support expanding beam measurement capabilities (up to 256 beams vs legacy 64) and unified solutions that work across BM-Case 1/2. They oppose introducing dedicated AI/ML activation signaling and extending TCI state mechanisms for future time instances, arguing these add complexity without significant benefit. Their stance emphasizes cell-specific rather than cross-cell associated IDs to preserve proprietary information and reduce network management burden.
