摘要

考虑到超5g无线通信所需的特性，如更高的频谱效率和能量效率，无蜂窝大规模MIMO(mMIMO)是有前途的技术之一。在本文中，我们提出了一种在无蜂窝毫米波mMIMO系统中实现更高能效的接入点(AP)开关开/关(ASO)方案，该方案根据系统中AP的重要性决定的顺序打开/关闭AP。数值结果表明，与传统方案相比，该方案提高了无小区毫米波mimo系统的能效性能。

Performance analysis of Access Point Switch ON/OFF schemes for Cell-free mmWave massive MIMO UDN systems

Considering required features for beyond-5G wireless communication, such as higher spectral efficiency and energy efficiency, cell-free massive MIMO(mMIMO) is one of the promising technologies. In this paper, we propose an Access Point(AP) Switch ON/OFF (ASO) scheme in cell-free mmWave mMIMO systems for higher energy efficiency, which switch on/off APs based on the order determined by the importance of APs within the systems. Numerical results show that the proposed scheme improves the energy efficiency performance of cell-free mmWave mMIMO systems compared to the conventional schemes.
