Abstract
With the wide application of 5G technology,the global industry has initiated research and exploration on the next stage of 5G evolution technology.5G-A has made significant upgrades in both functionality and coverage.Compared with 5G,it will achieve re-markable improvements in network speed,latency,and connection numbers.These performance enhancements pose more stringent re-quirements on the carrying capacity of metropolitan transmission networks.This paper deeply analyzes the key technical requirements of metropolitan transmission networks for 5G-A applications,elaborates on the service requirements and performance indicators of 5G-A,and thoroughly discusses the specific applications of ultra-high-speed optical transmission technology,small-granularity slicing technol-ogy,and network intelligence technology in metropolitan transmission networks,aiming to provide highly valuable technical references for building efficient,reliable,and flexible 5G-A metropolitan transmission networks.关键词
