[Abstract] 5G transmission is one of the key technologies supporting 5G applications in the future, and it has become a hot spot in the field of technical research and standardization. In this paper, the progress of the main standard organizations related to 5G transmission are introduced, including international telecommunication union standardization sector (ITU-T), institute of electrical and electronics engineers (IEEE), optical internetworking forum (OIF) and so on. 5G transport requirements, as well as transport solutions of slice packet network (SPN) /flexible Ethernet (FlexE), mobile OTN (M-OTN) / flexible OTN (FlexO), time sensitive network (TSN), and ultra-high precision time synchronization are involved. It is pointed out that 2018 will be the key window period for the standardization of 5G transport.
