The related technol?ogies for 5G NR can mainly be categorized into four areas, namely, 1) new mod?ulation and coding algorithms including multi?user superposition and shared access, enhanced waveform generation and advanced error?correction coding;展开更多

With 2G, 3G and 4G, the peak service rate is the dominant metric that distinguishes these three generations. 5G will significantly increase the peak service rate but will also dramatically increase energy efficiency, frequency efficiency, spectral effi- ciency, and efficiency of other resources. It will dramatically increase flexibility, ca- pacity, coverage, compatibility and convergence. In this way, it will salisfy the in- creasing demands of emerging big-data, cloud, machine-to-machine, and other ap- plications. The successful development and deployment of 5G technologies will be challenging and will require huge effort from industrry, academia, standardizalion organizations, anti regulatory authorities.展开更多
