摘　　要：对Sub-6 GHz频段和毫米波频段可重构智能超表面(RIS)辅助多输入多输出(MIMO)通信信道进行了室内热点(InH)场景下的信道测量。基于上述信道测量结果,研究了RIS辅助通信信道修正浮动截距(FI)模型,并对模型的准确性以及参数特性进行了验证。对RIS辅助通信信道在多频段的传播特性进行了分析,包括路径损耗增益、路径损耗因子(PLE)、时间色散等。上述信道测量和建模结果将为RIS辅助通信系统的实际应用奠定基础。The channel measurements and modeling are conducted for reconfigurable intelligent surface(RIS)-assisted multiple-input multiple-output(MIMO)communications in an indoor hotspots(InH)scenario at the Sub-6 GHz band and millimeter wave band.Based on the channel measurement results,the modified floating-intercept(FI)path loss model for RIS-assisted wireless communication is investi-gated,whose accuracy and parameter properties are verified.Moreover,the propagation characteristics for RIS-assisted channels,including path loss gain,path loss exponent(PLE),time dispersion,etc.,are analyzed at the multi-frequency band.These channel measurements and modeling results would lay the foundation for future applications of RIS-assisted communication systems in practice.
