摘　　要：5G无线技术伴随着付出的巨大努力,来说明、设计、部署和标准化正在到来的无线网络。人工智能(AI)和机器学习(ML)技术能够很好地支持5G最新技术,这些技术有望为即将到来的用例和服务提供高数据速率,例如大规模机器类型通信(mMTC)、增强型移动宽带(eMBB)和超可靠的低延迟通信(uRLLC)。在物联网范式中,这些服务肯定会帮助在几毫秒延迟内的吉比特数据。本文研究讨论了5G技术和特点,5G小蜂窝架构和5G小蜂窝工作模式,并专注于超密集小型蜂窝(UDSC)场景中的切换管理。The fifth generation(5G)wireless technology emerged with marvelous effort to state,design,deployment and standardize the upcoming wireless network generation.Artificial intelligence(AI)and machine learning(ML)techniques are well capable to support 5G latest technologies that are expected to deliver high data rate to upcoming use cases and services such as massive machine type communications(mMTC),enhanced mobile broadband(eMBB),and ultra-reliable low latency communications(uRLLC).These services will surely help Gbps of data within the latency of few milliseconds in Internet of Things paradigm.This paper studies and discusses 5G technologies and features,5G small cell architecture and 5G small cell operating modes,and focuses on handover management in ultra-dense small cell(UDSC)scenarios.
