摘要：

This paper addresses downlink cooperation at a system level. Cooperation between Base Stations is an alternative to macrodiversity to provide QoS continuity in case of mobility. We propose a Radio.Resource Management strategy for the relay channel, made of relayed users identification, resource allocation. and power control in an OFDMA-based system. Four scheduling methods are tested for power allocation in inter-cell interference environment: Globally Optimal, Proportional Fair, Harmonic Mean Fair and Max-Min Fair. Cooperation brings additional gain, both in terms of throughput and fairness, with all fair schedulers.
