摘　　要：随着以下行为主的移动互联网业务迅速发展,以及新应用新场景等以上行为主的特色业务出现,5G需引入具备大带宽差异化的技术方案。现有2.6 GHz频段单个时隙配置难以同时匹配两大类业务的需求,提出灵活双工组网方案,从灵活双工配置方案需求和目标出发,聚焦于干扰共存评估体系和干扰优化方案的研究进展,并根据试点结果提供相应的应用建议,实现了蜂窝系统首次使用TDD频段灵活双工组网,进一步引导产业提升灵活双工性能和技术成熟度。With the rapid development of the major downlink mobile Internet services and the emergence of the major uplink featured services in new applications and scenarios,5G requires to introduce technical solutions with large bandwidth and differentiation.It is difficult to simultaneously meet the requirements of two major types of services with the single slot configuration in the existing 2.6 GHz frequency band.Therefore,this paper proposes a flexible duplex networking solution,which starts from the requirements and targets of the flexible duplex configurations and focuses on the research progress of the interference coexistence evaluation system and interference optimization solution.Furthermore,according to the results of field trial,the application suggestions are provided,and the flexible duplex network in TDD band is realized for the first time in cellular systems,which further guides the industry to improve the performance and technical maturity.
