ZTE opposes Option 1 for UE-side model inference applicability, arguing it causes substantial waste of air interface resources and complicates NW scheduling. They support Option 3, emphasizing its compatibility with legacy CSI-ReportConfig design. ZTE proposes that AI/ML beam management feature groups be defined at least per sub-use case level (BM-Case1, BM-Case2), with condition combinations aligned between NW and UE outside UE capability indication to support future extensions. They argue that the provision of associated ID in Step 3 should be optional and that inference configuration in Step 3 is unnecessary for determining applicability. ZTE requires that Step 4 reporting include condition combinations and model availability, while Step 5 inference configuration comprises associated CSI report configurations. Finally, they propose that functionality activation depends on CSI report temporal characteristics and that L1/L2 signaling for activation/deactivation should reuse existing CSI report mechanisms.

ZTE advocates FOR flexible and optional network-side signaling to minimize overhead while maintaining functionality, supporting sub-use-case level granularity for AI/ML beam management, and reusing existing CSI framework mechanisms. They push AGAINST mandatory associated ID signaling and unnecessary inference configuration in Step 3, arguing for implementation flexibility and backward compatibility with future AI/ML extensions.
