Energy-e ffi cient and high-spectrum-e ffi ciency wireless transmission

With the deployment and commercialization of the fifth-generation (5G) mobile communication networks, the access nodes and data volume of wireless networks are showing massive and explosive growth. In this paper, we firstly review the research progress on the energy-e ffi cient and spectrum-e ffi cient wireless transmission, from the perspectives of both latency and energy consumption. We then provide several solutions to high-e ffi ciency wireless transmission for the 5G wireless networks. Finally, we give some discussions about the future road for the design of energy-e ffi cient and spectrum-e ffi cient wireless transmission, which provides some theoretical reference for the system design of wireless networks and Internet of Things (IoT) networks.
