eMBB, URLLC, and mMTC 5G Wireless Network Slicing: A Communication-Theoretic View

Abstract

Enhanced mobile broadband (eMBB), massive machine-type communications (mMTCs), & highly- reliable reduced delay connectivity are three general capabilities that 5G cellular network is designed to offer (URLLCs). Network slicing can support service diversity by allocating resources to each service in order to guarantee efficiency and isolate it from other services. In order to slice the radio access network (RAN), resources are often distributed orthogonally across the services. In this study, the possible benefits of non-orthogonal RAN sharing resources in uplink communication from a collection of eMBB, mMTC, & URLLC devices to a shared ground station are examined. Contrary to traditional NOMA approaches, which include users with homogenous requirements and can thus be studied over a normal multi-access channel, the method is known as heterogeneity nonorthogonal multi-access (H-NOMA). The paper creates a communication theoretic model to take into consideration the disparate needs and traits of the 3 services. In order to ensure efficiency with non-orthogonal RAN slicing, the notion of dependability heterogeneity is proposed being a model paradigm which takes use of the various dependability needs throughout the applications. According to this research, H- NOMA can, in some regimes, result in substantial improvements in efficiency tradeoffs between the three basic functions as opposed to orthogonal slicing.
