Abstract
In this paper, an inter-cell interference coordination algorithm is proposed for a downlink OFDMA relay network with multicells. In the proposed algorithm, the resource allocation problem is heuristically divided into subchannel allocation and subchannel restriction for interference coordination. Simulation results show that the proposed algorithm achieves higher cell edge user throughput and cell throughput than the proportional fair algorithm.
