论文摘要
在这项工作中，我们研究了具有多面板阵列（MPA）的全维多输入多输出（FD-MIMO）系统的代码簿设计。我们提出了新颖的代码手册，通过研究面板的物理特性和比对，允许MPA FD-MIMO系统精确的光束结构。我们特别利用了垂直方向的一组天线的特征，比沿水平方向的天线更相关。与传统的代码簿相比，这可以经济地使用反馈位。通过在多个部分（例如梁振幅和使用增强学习）上的多个部分上分配反馈位，进一步改进了代码手册。数值结果证实了拟议方法在性能和计算复杂性方面的有效性。
In this work, we study codebook designs for full-dimension multiple-input multiple-output (FD-MIMO) systems with a multi-panel array (MPA). We propose novel codebooks which allow precise beam structures for MPA FD-MIMO systems by investigating the physical properties and alignments of the panels. We specifically exploit the characteristic that a group of antennas in a vertical direction exhibit more correlation than those in a horizontal direction. This enables an economical use of feedback bits while constructing finer beams compared to conventional codebooks. The codebook is further improved by dynamically allocating the feedback bits on multiple parts such as beam amplitude and co-phasing coefficients using reinforcement learning. The numerical results confirm the effectiveness of the proposed approach in terms of both performance and computational complexity.
