Inter-cell interference (ICI) is considered as the most critical bottleneck to ubiquitous 4th generation cellular access in the mobile long term evolution (LTE). To address the problem, several solutions are under evaluation as part of LTE-Advanced (LTE-A), the most promising one being coordinated multi-point joint transmission (CoMP JT). Field tests are generally considered impractical and costly for CoMP JT, therefore the need to provide a comprehensive and high-fidelity computer model to understand the impact of different design attributes and the applicability use cases. This paper presents a novel approach to the modelling and simulation of an LTE-A system with CoMP JT by means of discrete event simulation (DES) using OPNET modeler. Simulation results are provided for a full buffer traffic model and varying the characteristics of the interface between cooperating points. Gains of up to 120% are achieved for the system throughput when using CoMP JT.
