This work focuses on the scheduling problem in LTE Advanced wireless networks.
In the first part we describe the LTE Advanced simulator developed using the OMNeT++ framework.
The second part contains the design of a Multi-User MIMO scheduler supporting QoS. Here we propose a modular scheduling process where transmission mode selection, frequency domain allocation, QoS demand and fairness among users are managed all together, respecting the constraints imposed by the LTE standard.
The last part contains the performance evaluation of the scheduler designed.
Simulation results show that the procedures developed for transmission mode selection achieve a performance very close to that of an optimal mathematical model, formalized for this purpose.
Furthermore simulations show that the proposed solution for QoS support manages to meet the constraints of real-time traffics, ensuring fairness among users and good throughput results at the same time.
