摘要
高分辨率II型CSI反馈是4G (LTE)和5G (NR)之间的关键区别。然而，Type II CSI报告的巨大反馈开销是实际部署中UE实现的瓶颈。本文提出了一种基于空频压缩的II型CSI开销降低方法。系统级仿真结果表明，在显著降低CSI开销的情况下，可以实现与II型CSI相似的性能。
High-resolution Type II CSI feedback is a key differentiator between 4G (LTE) and 5G (NR). The large feedback overhead of Type II CSI reporting, however, is a bottleneck for UE implementations in real deployments. In this paper, a space-frequency compression based Type II CSI overhead reduction has been proposed. The system-level simulation results are provided to show that the performance similar to Type II CSI is achievable with significantly reduced CSI overhead.
