MAC sub-layer design to reduce interference in LTE networks
Tan, Kim Hong

In this paper, 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. The solution seeks to achieve an optimum point of tradeoff between improvement in the SIR and the acceptable amount of the unutilized resources.
