广东省电信规划设计院有限公司的技术团队打造，本书作者来自通信网络咨询、规划与设计工作一线，长时间跟踪移动通信技术和网络的发展和演进。自2013年起，广东省电信规划设计院有限公司的技术团队开启了对5G技术的跟踪和研究、对5G网络的思考和预研；2017年年底，技术团队参与推动新一代信息基础设施建设工程5G规模组网试点项目的通信运营商落地实施、深圳市为中国特色社会主义先行示范区而部署的5G行业应用试验网的规划设计、通信运营商5G商用网络的前期准备和规划设计、部分行业用户5G应用试点示范项目的咨询和设计等一系列有意义的工作，积累了成果和经验。 书中着重介绍了5G的发展历程、愿景、网络关键性能指标、标准等基础性内容和5G频谱这个重要的性资源的发展状况，描述了5G网络架构重构的思路和技术，以及在此思路的指导下重新构建出的网络服务化架构及主要功能实体，还介绍了5G网络的部署和演进部分内容。 书中涉及了5G核心网的内容，在技术层面主要介绍了网络切片和多接入边缘计算这两个5G主要特征，在网络建设层面分享了独立组网（Standalone，SA）核心网建设要点、规划设计流程和算法以及非独立组网（Non-Standalone，NSA）过渡方案等经验和成果。以5G无线网功能需求为起点逐一介绍了超密集组网、无线网控制与承载分离、小区虚拟化、无线网络资源管理、终端直连、网络频谱共享等关键技术，还介绍了5G空口中接口技术的协议栈、关键技术和空口信道等主要内容，详细介绍了大规模天线技术的发展和理论基础、大规模多进多出（MassiveMultiple-Input Multiple-Output，Massive MIMO）技术的理论、传输方案和应用场景；在网络建设层面主要分享了5G无线网规划设计的经验和成果，包括规划的流程和方法、仿真的关键流程和参数、网络部署方式、当前典型的基站设备类型、基站设计、设计文件及概预算编制、5G室内分布系统设计、5G网络对承载网的需求等实用性内容。梳理了近年来我国多地政府为推动5G 快速发展所发布的规划、行动方案、特色应用示范和保障措施，介绍了5G技术与物联网、大数据、云边协同、人工智能、增强现实 / 虚拟现实（Augmented Reality/Virtual Reality，AR/VR）等新技术的融合应用，以及赋能多种新应用的可能性、远景和当前的尝试等内容。 
内容简介
本书的内容涵盖5G网络系统架构、5G核心网关键技术、5G无线网关键技术、无线网空中接口、大规模天线技术、5G核心网规划设计以及5G无线网规划设计，与此同时展望了5G未来发展的方向和前景。读完本书后，读者将对5G网络的核心网和无线网规划仿真方法有一个新的认识。5G核心网引入了服务化架构、网络切片和多接入边缘计算等新特性，组网方案与4G核心网有较大的差异；5G无线网采用基于差异化需求的规划方法，与传统方法也有很大的区别。以5G网络工程设计为例，读者将对5G网络部署方式、基站设备选型、基站设计、设计文件和概预算编制、5G室内分布系统设计方法等有一个系统的认识。本书适合从事移动通信网络（包括核心网、无线网）的技术人员与管理人员阅读，也可作为高等院校与通信相关专业师生的参考书。
