Investigations of 5G Multiple Radio Access Technology Performance and Resource Selection Behavior

A simulation platform is developed and presented in this paper for investigations of 5G Multiple Radio Access Technology (Multi-RAT) performance and resource allocation behavior by considering the mixture of new radio network technology aspects and decision criteria. This paper is more focusing on the OSI Layers 1-2 (physical and media access) and performance analyses, rather than the aspects in the higher OSI layers like radio resource management, load sharing, and resource selection procedures. These were investigated in previous projects. The effect of these processes can be considered by an overhead factor. The default parameters for different RATs and mapping of different services to these technologies are defined and used for simulations, are continuously checked with recommendations and the best practice parameter settings, correspondingly verified and modified. The goal is to use simple, but flexible simulation methods, approximations and propagation models and by using Matlab to investigate typical Multi-RAT network scenarios in macro-, micro-, pico-urban environment fast and efficiently.
