The paper is to limit inter-cell interference in two hops cooperative communication systems. The authors propose to exploit the standard half-duplex limitation of relays so as to coordinate in time and frequency the resource allocation of a cluster of neighbor cells, and then to adapt resource allocation to changes in the communication context. Simulation results show how their proposed allocation modes permit to outperform classical modes in terms of cooperation effectiveness, power consumption and perceived Quality of Service (QoS).
