论文摘要
在本文中，我们提出了通过可重构智能表面（RISS）启用的近场毫米波多手通信系统的低架空梁管理方法。我们设计了一种新型的可变宽度层次结构段截面代码本适用于RI的近场和远场，并为RIS相移和收发器波束形式提供了快速对齐算法。显示了指示性能评估结果，与各种基准方案相比，验证了所提出的方法的有效性。
In this paper, we present a low overhead beam management approach for near-field millimeter-wave multi-antenna communication systems enabled by Reconfigurable Intelligent Surfaces (RISs). We devise a novel variable-width hierarchical phaseshift codebook suitable for both the near- and far-field of the RIS, and present a fast alignment algorithm for the RIS phase shifts and the transceiver beamformers. Indicative performance evaluation results are shown, verifying the effectiveness of the proposed approach in comparison with various benchmark schemes.
