Abstract

Classical FDM/TDM cellular networks, such as GSM, avoid the reuse of the same set of frequencies in close-by cells. This is necessary in order to keep the interference level in the cells below a certain threshold. As a drawback, each cell only uses a fraction of the total frequency resources. Eventually, it would be desirable to fully utilize the complete available frequency spectrum in each cell. In this paper, we demonstrate how beamforming antennas in combination with an intelligent interference coordination in-between cells can be used to achieve this goal. We investigate the tradeoff between the achievable Signal-to-Interference Ratio (SIR) in each cell and the effective utilization of the frequency resources at the example of a state-of-the-art 802.16e system. We conclude that the investigated mechanisms open the way to future wireless access networks with an efficient utilization of the available frequency spectrum.
