Abstract：The ubiquitous connectivity scenarios of 6G demand enhanced capabilities for three-dimensional (3D) coverage expansion. Key technologies, including intelligent flexible architecture for coverage extension, unified air interfaces, and intelligent multiple access are introduced. The plug-and-play access mechanism for 6G 3D coverage expansion is explored through two approaches: optimizing existing nodes and integrating new access nodes. A process mechanism and signaling protocol design supporting plug-and-play node expansion are proposed. Additionally, the mechanism's performance is validated in high-speed mobility scenarios, confirming its efficacy in enhancing 6G 3D coverage networks.
