摘　　要：通过对5G与LTE在移动性空口测量差别的分析,指出了5G引入波束赋形后对移动性空口测量的影响,提出了下行测量增强技术及基于下行测量的移动性管理,并针对一些特定场景和业务需求,提出了上行测量技术及基于上行测量的移动性管理,从而可保证UE在5G网络移动时有比较好的移动性性能。It analyzes the differences on mobility measurement between 5G and LTE,and illustrates the impacts of beamforming on 5G mobility measurement. It figures out the downlink mobility measurement enhancements and the corresponding mobility measurement. And at the same time,it gives the solution of the uplink mobility measurement and the corresponding mobility management for some specific scenarios and service requirements. With these enhancements and solutions,it can guarantee UE has a good mobility performance.
