论文摘要

带有波束形成的大量多输入多输出系统是第五代和未来第六代网络的关键组成部分。但是,在某些情况下,如果BS长期为同一用户服务,并且在某些传播条件下,此类系统会降低其发射功率,以避免产生不必要的电磁场暴露区域,超过了监管阈值,超出了BS周围圆圈的圆圈,从而限制了人们与BS天线之间的距离。这种功率降低会大大降低目标用户接收的功率。最近,已经提出了通过自我调整可重构智能表面从最大比率传输边界得出的自我调整的智能表面来帮助的博览会意识到的方案:截断了光束形成。但是,这种方案非常复杂。在本文中,我们提出了一种新颖且低复杂性的可重新配置智能表面辅助辅助光束方案,称为均衡光束形成,该方案将最大比率传输应用于角度均衡的虚拟传播通道。我们的模拟表明,我们所提出的方案在遵守博览会调节的同时优于减少的光束形成方案。

Massive Multiple-Input Multiple-Output systems with beamforming are key components of the 5th and the future 6th generation of networks. However, in some cases, where the BS serves the same user for a long period, and in some propagation conditions, such systems reduce their transmit power to avoid creating unwanted regions of electromagnetic field exposure exceeding the regulatory threshold, beyond the circle around the BS that limits the distance between people and the BS antenna. Such power reduction strongly degrades the received power at the target user. Recently, exposition aware beamforming schemes aided by self-tuning reconfigurable intelligent surfaces derived from maximum ratio transmission beamforming, have been proposed: truncated beamforming. However, such scheme is highly complex. In this paper, we propose a novel and low complexity reconfigurable intelligent surface aided beamforming scheme called Equalized beamforming, which applies maximum ratio transmission to an angularly equalized virtual propagation channel. Our simulations show that our proposed scheme outperforms the reduced beamforming scheme, whilst complying with the exposition regulation.
