ZTE · 9.1.1

ZTE proposes utilizing functionality-based LCM without model ID based signaling for AI/ML beam management, arguing that model transfer challenges and existing associated ID support diminish the need for model-ID-based approaches. They support bitmap-based methods for beam information reporting to reduce overhead by up to 63.5% in typical settings, and propose threshold-based beam reporting with configurable minimum/maximum beam counts. For NW-side data collection, ZTE supports L1 signaling irrespective of purpose and recommends differential L1-RSRP reporting with larger quantization steps. Regarding UE-sided models, they prefer configuring associated IDs per CSI report configuration and support extending Rel-17 TCI state signaling for multiple future time instances in BM-Case2. For performance monitoring, ZTE supports beam prediction accuracy and RSRP prediction accuracy as primary metrics and requires failure detection to be based on consecutive monitoring results within a predefined window.

ZTE strongly advocates FOR functionality-based lifecycle management over model-ID-based approaches, arguing it reduces complexity and leverages existing UE capability frameworks. They push FOR bitmap-based beam reporting methods to significantly reduce signaling overhead (up to 63.5% reduction) and support flexible quantization with larger step sizes (4 dB vs 2 dB) for differential RSRP reporting. ZTE is AGAINST overly complex associated ID schemes due to signaling overhead and proprietary information disclosure risks, instead favoring performance monitoring-based approaches for consistency.
