Abstract

This paper addresses the co-channel cell interference (CCI) mitigation in multi-cell OFDMA systems through cooperative relaying and frequency reuse partitioning. In the considered system, each cell is divided into two regions: the central region and the edge region. The frequency reuse factor (FRF) is set to 1 in the central region and fractional reuse factors of 7/3 or 7/4 are used in the edge region by dividing it respectively into three or four sectors. A fixed relay station (RS) by sector, which amplifies and forwards the received signal to the mobile, is placed at the border base station side of the central region. Simulation results are used to show the improvement of the proposed cooperative scheme compared to the performance of similar architecture without relays.
