To meet the ambitious peak data rate and spectral efficiency target for the UTRA Long Term Evolution (LTE), Multiple-Input Multiple-Output (MIMO) is identified to be one of the most essential technologies for LTE.While MIMO is a widely
researched topic, most studies disregard the interaction of MIMO with other essential enhancement mechanisms in the system including Link adaptation (LA),Hybrid ARQ (HARQ) L1 retransmission, packet scheduling, etc. Therefore, this
PhD study focuses on the efficient integration of MIMO in the LTE system by making a careful design and analysis of the interoperation of different gain mechanisms at different layers, rather than an evaluation of their individual performance
potential only. More specifically, the investigation exploits new algorithms for MIMO, which jointly optimize the LTE system with reasonable complexity and low signalling requirements. An important consideration for the optimum interoperation/integration is the overall throughput performance at both link and system level, where the associated issues like the range of available SINRs, the signaling overhead, and user fairness become important. The complexity of combining those realistic factors and multiple gain mechanisms often require Monte Carlo simulations.
However, theoretical analysis under ideal assumptions is also useful to gain insight on upper bounds and to support and verify the Monte Carlo simulation work. Thus both approaches are utilized in this Ph.D. study.
