摘　　要：5G时代,室内覆盖需提供大容量能力满足toB和toC场景需求,解决室分容量问题,传统方式为小区分裂后的多小区同频组网或多载波扩容,不能显著增加小区容量。文章探索了借助Massive MIMO技术改善5G网络覆盖性能容量问题,创新地将Massive MIMO技术应用在5G室内分布系统中,有效解决了5G绕射能力差、室内覆盖不足的问题。在5G室内高负荷场景中,通过将Massive MIMO(大规模天线)技术引入到室内系统中,化干扰为增强信号,通过联合Beamforming和多用户MIMO提升网络容量与用户体验。In the 5Gera,indoor coverage needs to provide large capacity to meet the needs of toB and toC scenarios,solving the problem of room division capacity.Traditional methods such as multi cell co frequency networking or multi carrier expansion after cell division cannot significantly increase cell capacity.This article explores the use of Massive MIMO technology to improve the coverage performance and capacity of 5Gnetworks.It innovatively applies Massive MIMO technology to 5Gindoor distribution systems,effectively solving the problems of poor 5Gdiffraction ability and insufficient indoor coverage.In 5Gindoor high load scenarios,by introducing Massive MIMO(Massive Antenna)technology into indoor systems,interference is turned into enhanced signals,and network capacity and user experience are improved by combining Beamforming and multi-user MIMO.
