5G Mobile Technologies and Early 6G Viewpoints

Abstract

Design of each successor mobile technology assures improved and advanced functionality features compared to its predecessor. Machine Learning and generally Artificial Intelligence (AI) is becoming necessity for further expansion of the beyond 5G mobile world. AI-assisted IoT services, data collection, analytics and storage should become native in the beyond 5G era. 5G introduces New Radio (NR) in sub-6 GHz bands and also in mmWave bands above 24 GHz, network virtualization and softwarization, which means that Next Generation Core and 5G NR access network are built by using different functions in split user and control planes that introduces the network slicing approach. Enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC) and Ultra-Reliable Low-Latency Communication (URLLC), that are provided via separate network slices as logically separated network partitions are the key 5G services that constantly will increase the traffic volume and the number of connected devices. Terahertz and visible light communication and fundamental technologies like compressed sensing theory, new channel coding, large-scale antenna, flexible spectrum usage, AI-based wireless communication, special technical features as Space-Air-Ground-Sea integrated communication and wireless tactile network are few of the novelties that are expected to become a common network standard available beyond 2030.

The Roadmap to 6G Security and Privacy

“…Holographic telepresence is a 6G application which can project realistic, full-motion, real-time three-dimensional (3D) images of distant people and objects with a high level of realism rivaling of the physical presence [53] (e.g.,3D video conferencing and news broadcasting [54]). An extremely large bandwidth is required to enable holographic communication.…”

Survey on 6G Frontiers: Trends, Applications, Requirements, Technologies and Future Research

“…HT can project realistic, full-motion, real-time threedimensional (3D) images of distant people and objects with a high level of realism rivaling of the physical presence [98]. It can be used for full-motion, 3D video conferencing and news broadcasting or TED talk like applications [17], [99]. HT captures footage of people and surrounding objects, which are compressed and transmitted over a broadband network, in the initial stage.…”
