FUTUREWEI · 9.1.4.1

Futurewei advocates FOR using enhanced Rel-16 eType II codebook with new parameters for both data collection and monitoring to achieve better performance, despite overhead concerns. They push FOR differentiated delivery methods based on latency requirements (over-the-air for Direction B, upper layer signaling for Direction A) and support comprehensive quantization specification impact studies. They are AGAINST rushing into proxy model adoption without thorough LCM complexity analysis and advocate for careful performance evaluation before supporting precoded RS-based monitoring methods.

Futurewei advocates FOR using Rel-16 eType II codebook with new/enhanced parameters for data collection and monitoring to achieve better performance, even with additional overhead concerns. They push FOR comprehensive analysis of inter-vendor collaboration options through detailed tables showing issue applicability, and support using upper layer signaling to reduce air-interface overhead for less latency-sensitive options. They demonstrate strong support for temporal CSI compression (Case 2) showing significant performance gains over legacy approaches even with UCI loss.
