6G: typical applications, key technologies and challenges

Abstract

2020 marked the first year of the era of 5G commercialization in China and the inception of worldwide research in 6G.Compared with 5G networks, 6G networks will have larger information capacity, higher transmission rate, lower transmission delay, larger number of connected devices, higher spectrum efficiency, higher energy efficiency, and can support applications with higher mobile speed.Therefore, 6G networks will involve many new key technologies and also face many challenges.The background, development, typical applications, performance indicators, network architecture, key technologies and future challenges of 6G were systematically reviewed, which are expected to provide some reference for future 6G networks related research.
