With the 5 G commercialization granted in 2019

we are entering the first year of the 5 G era. More than 60 percent of typical industrial applications of 5 G are also the application scenarios of artificial intelligence in various industries. An intelligent 5 G network is the foundation to assure the success of 5 G+AI applications and also is the key to deliver expected efficiency and further lower network operation cost. New challenges are continuously posed by these ever-growing applications. In this paper

we describe the technical progress of 5 G intelligence

5 G+AI application status as well as the main challenges we are facing. Researchers and engineers in industries and academies need to find a new way to efficiently research

develop

and collaborate to conquer these challenges with the speed required by the market.
