摘要

在5G中使用毫米波（mmWave）是蜂窝网络的一个里程碑，它前所未有地提高了通信容量。然而，移动用户很难满足于当前毫米波业务覆盖范围短、易受阻塞的问题，这也削弱了行业对毫米波推广的信心。为了解决这一困境，在6G中，需要有效地使用中继技术，如模拟中继器和可重构智能表面（RIS），以增强现有毫米波站的覆盖范围和容量。本文介绍了一种由大量模拟中继站组成的毫米波大规模中继系统，为移动用户构建人工信道。为了提高毫米波多用户多输入多输出（MU-MIMO）的性能，提出了一种主动利用阻塞环境来减少干扰和优化系统容量的用户调度方法。数值分析和仿真验证了所提出的系统和方法。

Millimeter-Wave Massive Analog Relay MU-MIMO With Blocking-Empowered User Scheduling Toward 6G

The utilization of millimeter wave (mmWave) in 5G represents a milestone in cellular networks, which unprecedentedly enhances communication capacity. Nevertheless, mobile users are hard to satisfy with the short coverage and vulnerability to blockage of current mmWave services, which also undermines industrial confidence in mmWave promotion. To solve this dilemma, in 6G, relay technologies, such as analog repeaters and reconfigurable intelligent surfaces (RIS), need to be effectively used to enhance the coverage and capacity of existing mmWave stations. In this paper, we introduce a mmWave massive relay system, consisting of massive analog relay stations to construct artificial channels for mobile users. To enhance the performance of mmWave multi-user multiple-input and multiple-output (MU-MIMO), we propose a user scheduling method that actively exploits the blocking environment to reduce interference and optimize the system capacity. Numerical analysis and simulations are conducted to validate the proposed system and methods.
