Abstract
In this thesis, synergy between the physical layer and the Medium Access Control (MAC) layer of a Long Term
Evolution (LTE) network is exploited to reduce the co-channel interference in both the forward and reverse channels.
By doing such cross-layer optimization analysis, physical and MAC layer control decisions reach their full potential
when they are designed in an integrated manner.
The proposed solution focuses on the integration of the concepts of orthogonal frequency-division multiple
access (OFDMA), sectorization, and Latin Square to improve the signal-to-interference ratio (SIR) with the most
effective resource utilization. Sectorization in the physical layer alone is able to improve the SIR, however, by also
implementing OFDMA and Latin Square techniques to reduce the effect of co-channel interference, better SIR can be
achieved. There is some impact on resource utilization, however. The solution seeks to achieve an optimum point of
tradeoff between improvement in the SIR and the acceptable amount of the unutilized resources.
