Study on power feeding system for 5G network

With the rapid development of Information and Communication Technology (ICT), the fifth generation communication technology (5G) has become the focus of the field and it has been given great hope to change the way of human life. Base stations, as the key facilities of communication technology, are facing great challenges of upgrading. In one hand, the power consumption increases in Macro base stations, in the other hand, as the frequency increases, the coverage of single 5G decreases. It is discussed the difficulties of large-scale power supply for the 5G base station and analyzes several solutions to solve the problem of power supply for the 5G base station in this paper. At the same time, this paper also introduces the progress of 5G standardization in International Telecommunication Union (ITU) and in China Communications Standards Association (CCSA).
