| Abstract: | In order to satisfy the user service experience of the new emerging applications in mobility scenarios and ensure that the network can provide users with reliable and consistent services,this paper focuses on investigating the technologies of multi-rat dual connectivity(MR-DC)and mobility enhancement,including key procedures such as handover and primary secondary cell(PSCell)changes.In addition,the research content of 3GPP Rel-16 is briefly introduced in terms of MR-DC and mobility enhancement,and then the enhanced technical solution of the MR-DC and standard impact of Rel-17 are analyzed.Furthermore,the potential research directions of technical evolution ideas and standardization for Rel-18 are prospected. |
