论文摘要
网络控制的中继器（NCR）最近被认为是3GPP版本18的研究项目，并且在工作项目中进行了讨论。在本文中，我们介绍了NCR的概念，作为一种可能的低复杂设备，以支持网络致密化并将NCR的性能与可重构智能表面（RISS）所实现的NCR相提并论。对于使用不同的波束形成方法和RIS硬件损伤模型的情况，提出了结果。此外，我们介绍了3GPP版本18 NCR工作项目的目标，并研究了不同参数对NCR辅助网络性能的影响。正如我们所显示的，通过适当的部署，NCR/RIS的存在可以大大提高网络性能。
Network-controlled repeater (NCR) has been recently considered as a study-item in 3GPP Release 18, and the discussions are continuing in a work-item. In this paper, we introduce the concept of NCRs, as a possible low-complexity device to support for network densification and compare the performance of the NCRs with those achieved by reconfigurable intelligent surfaces (RISs). The results are presented for the cases with different beamforming methods and hardware impairment models of the RIS. Moreover, we introduce the objectives of the 3GPP Release 18 NCR work-item and study the effect of different parameters on the performance of NCR-assisted networks. As we show, with a proper deployment, the presence of NCRs/RISs can improve the network performance considerably.
