摘要
5G与LTE双连接,两者优势互补,在不同制式、不同频段、不同站点和不同业务诉求之间实现有效的区域级协同和灵活高效的分配资源,是实现5G NR早期快速部署和网络平滑演进的有效途径。分析了5G与LTE双连接应用的必要性,研究了5G的双连接架构特点,探讨了5G的双连接架构选择思路,为未来5G网络双连接技术的应用提供了参考。
5 G and LTE dual connectivity,which complement each other’s advantages,achieve effective regional coordination,flexible and efficient resource allocation between different systems,different frequency bands,different sites and different business demands,is an effective way to realize the early rapid deployment of 5 G NR and the smooth evolution of the network.It analyzes the necessity of 5 G and LTE dual connection application,studies the dual connection architecture of 5 G,and discusses the choice of dual connection architecture of 5 G,which provides reference for the application of the 5 G network dual connection technology in the future.
