Performance analysis on reconfigurable intelligent surface and network-controlled repeater in 3GPP release-18
Abstract: As a candidate technique to achieve sixth-generation wireless communication (6G), reconfigurable intelligent surface (RIS) has become popular in both academia and industry. For better exploration of the advantages of RIS, we compare the performances of RIS and network-controlled repeater (NCR) in 3GPP release-18. We first theoretically analyze the received signal power and signal-to-noise ratio performances for both RIS and NCR. Then, we simulate the reference signal received power and signal-to-interference-and-noise ratio performances at the system level for both RIS and NCR in the frequency range 1 and frequency range 2 bands. Finally, several insights on engineering applications are given based on the comparison between RIS and NCR.

摘要：作为实现6G的候选技术之一，可重构智能表面（reconfigurable intelligent surface，RIS）在学术界和工业界都备受瞩目。为了更好地探索RIS的优势，本文将RIS与3GPP release-18中的网络控制中继器（network-controlled repeater，NCR）的性能进行比较。首先，从理论上分析RIS和NCR的接收信号功率和信噪比性能。接着，模拟了RIS和NCR在频率范围1和频率范围2波段的系统级参考信号接收功率和信干噪比性能。最后，根据RIS和NCR的比较结果，对工程应用提出一些见解。
