论文摘要
第三代合作伙伴项目（3GPP）考虑了网络控制的中继器（NCR）和可重构智能表面（RIS），是毫米波（MMW，30-300 GHz频率）5G和6G网络的有效候选者，以抵消大型路径和渗透损失。如今，没有确定的答案对两种技术中的哪种更适合覆盖范围扩展，因为现有的比较研究专注于与沟通相关的指标或非常大规模的分析，而没有物理层的细节或环境考虑。本文旨在根据城市场景的覆盖范围比较NCR和RIS解决方案。数值结果表明两种技术可能使用，这表明偏爱RIS或NCR不仅取决于它们的物理能力和成本（例如，天线元素的数量，NCR面板之间的角度分离等），还取决于环境几何形状。
Network-controlled repeaters (NCR) and reconfigurable intelligent surfaces (RIS) are being considered by the third generation partnership project (3GPP) as valid candidates for range extension in millimeter-wave (mmW, 30-300 GHz frequency) 5G and 6G networks, to counteract large path and penetration losses. Nowadays, there is no definite answer on which of the two technologies is better for coverage extension, since existing comparative studies focused either on communication-related metrics only or on very large-scale analysis, without physical layer details or environmental considerations. This paper aims at comparing NCR and RIS solutions in terms of coverage in an urban scenario. Numerical results suggest a possible usage of both technologies, showing that preferring RIS or NCR depends not only on their physical capabilities and cost (e.g., the number of antenna elements, the angular separation between panels for NCR, etc.) but also on environment geometry.
