Full Frequency Reuse in Mobile WiMAX and LTE Networks with Sectored Cells

Abstract : Frequency reuse is an important topic in wireless communications systems. In this paper, we address the issue of frequency reuse in sectored cells which are subject to interference in the overlap regions of adjacent sectors. We propose to increase the number of sectors from 3 to 4 using conventional base station sector antennas with beam-width exceeding 120deg, which purposely creates large overlap regions between adjacent sectors. Rather than treating the signals of adjacent sectors as interference, we investigate sector cooperation for communication with users located in the overlap regions. Different scenarios are considered for user locations, and simulation results are given which illustrate the performance of the proposed schemes.
