6G-Enabled Ultra-Reliable Low-Latency Communication in Edge Networks

Seamless connectivity and ultra-reliable data transmission are among the ever increasing demands for a ubiquitous, smart, and automated future digital society with 5G technology. However, substantial delay restricted applications always invoke a problem with 5G and beyond 5G technologies due to long-distance communication and service deployment in the centralized cloud server. These limitations spur research initiatives for the coming generation of 6G technology that can concatenate a voluminous assortment of far-reaching terminal applications. In addition, edge computing is recognized as a pioneer of emerging technology to reduce energy and latency by offering ultra-reliable low-latency communication and computation services at the edge of the network. Motivated by the importance of the above mentioned technologies, in this article, we discuss the emerging 6G technology and its benefits toward edge networks for processing real-time applications. We shed light on several challenging issues for collaborating on 6G and edge computing, based on the review of 5G deployment, network coverage, technology requirement, and challenges. Further, future research directions of 6G-based edge computing are also discussed in order to integrate ultra-reliable 6G technology into the edge networks for processing real-time applications.
