Emerging Technologies and Challenges to Move Towards 6G Wireless Network

Abstract

5G is now in its early stages of commercialization. With its improved capabilities and innovative features, the fifth-generation (5G) network completely transforms the presently used wireless networks. Now academia and researchers' people are looking for new dimensions of applications where a high data rate is required with incredibly fast response times and excellent reliability. For handling new applications, new KPIs are required with the new network. For achieving a KPI of 6G, which is many times higher of 5G KPI, researchers are looking for new technologies. High-frequency THz signals are used for enhanced bandwidth and achieving high data rate, but THz signals have many losses. For meeting the targets of 6G KPI, and mitigating the demerits of THz signals, there are many technologies present like ultra-massive MIMO, distributed computing, ultra-channel coding, visible light communication, multiple access technology, and reconfigurable intelligent surfaces. For utilizing these technologies efficiently to catch up the speed of 6G, advance AI–based resource allocation and secure communication for 6G network deployment are the prerequisite, which is a major challenge. The present article proposes resource allocation on behavior modeling. Also, a layer-based model is present to handle user requirements in the present scenario. This article also includes a list of various ongoing 6G energy conservation projects and related technologies.
