  Research and development of mobile communications systems require a detailed
analysis and evaluation of novel technologies to further enhance spectral
efficiency, connectivity and reliability. Due to the exponentially increasing
demand of mobile broadband data rates and challenging requirements for latency
and reliability, mobile communications specifications become increasingly
complex to support ever more sophisticated techniques. For this reason,
analytic analysis as well as measurement based investigations of link level
methods soon encounter feasibility limitations. Therefore, computer aided
numeric simulation is an important tool for investigation of wireless
communications standards and is indispensable for analysis and developing
future technologies. In this contribution, we introduce the Vienna 5G Link
Level Simulator, a Matlab-based link level simulation tool to facilitate
research and development of 5G and beyond mobile communications. Our simulator
enables standard compliant setups according to 4G Long Term Evolution, 5G new
radio and even beyond, making it a very flexible simulation tool. Offered under
an academic use license to fellow researchers it considerably enhances
reproducibility in wireless communications research. We give a brief overview
of our simulation platform and introduce unique features of our link level
simulator in more detail to outline its versatile functionality.
