摘要

在5G-Advanced（5G-A）和6G阶段，智能超表面（reconfigurable intelligent surface，RIS）作为一种面向网络深度覆盖需求的辅助型技术，能够在满足网络稳定连续覆盖、多流增速等需求的基础上提供低成本、低功耗的解决方案。基于对RIS技术定位的分析，提出了基于智能超表面辅助的高低频协同组网架构，分析了基站与智能超表面协同部署的比例，针对智能超表面阵面引入邻频干扰的问题，提出了基于定制化带宽设计抑制邻频干扰方案，且面向基于基站与智能超表面协同组网，开展系统级仿真验证，验证不同终端分布条件下，智能超表面部署位置和阵元数对系统性能的影响。仿真测试结果表明，基于RIS辅助的网络能够明显提升边缘和弱覆盖区域，从而提升整个通信系统网络性能。

Abstract

Network assisted with reconfigurable intelligent surface is a kind of low-cost and low-power solution which can provide stable

continuous and ubiquitous connection to satisfy deep coverage requirements in 5G-Advanced (5G-A) and 6G era. A kind of reconfigurable intelligent surface assisted high and low frequency collaborative network architecture based on the positioning analysis of reconfigurable intelligent surface technology was proposed. The proportion of base station and reconfigurable intelligent surface collaborative deployment was analyzed. Furthermore

a interference reduction based on bandwidth design scheme was proposed to reduce adjacent frequency interference. System level performance simulation of network assisted with reconfigurable intelligent surface was verified to analyze the impact of reconfigurable intelligent surface deployment location and number of array elements under different UE distribution conditions. The simulation results show that the RIS-assisted network can significantly improve the edge and weak coverage area

so as to improve the network performance of the whole communication system.
