Abstract: The research and innovation window of 6G network is opened soon after the large scale commercialization of 5G in the world and especially in China. The global research progress of 6G network is briefly introduced and the tentative timeline of 6G requirements, technology and standard research are illustrated. The future traffic trend and typical use cases towards 6G network are investigated preliminarily. The vision and the key performance requirements as well as the potential enablers in the architecture, link, flow, inference and computing dimensions are established towards 6G network..We also anticipate the 6G potential enablers including self-driving network, the intelligent 3D-connectivity, the intelligent large-scale antenna array, the on-demand network topology and computing, as well as the beyond silicon computing and communication. Some innovation instances towards 6G from ZTE Corporation are presented such as the service-based radio access network (SBA-RAN), the smooth virtual cell (SVC), the intelligent reflective metasurface MIMO (IRS-MIMO) and enhanced multi-user shared access (eMUSA). We reveal that whether the 6G is a "evolution" or "revolution" network of 5G is mainly determined by the innovations of beyond-silicon computing which could maintain the sustainable development of Moore's law. Finally we outlook the pre6G innovation technologies that will be widely used in the evolved 5G network.
