Relaying and orthogonal frequency division multiple

access (OFDMA) are the accepted technologies for emerging

wireless communications standards. The activities in many

wireless standardization bodies and forums, for example IEEE

802.16 j/m and LTE-Advanced, attest to this fact. The availability

or lack thereof of efficient radio resource management (RRM)

could make or mar the opportunities in these networks. This

paper therefore provides a comprehensive RRM algorithm for

OFDMA-based multi-cellular fixed relay networks in a way to

ensure fairness among users with minimal impact on the network

throughput (in contrast, pure opportunistic RRM techniques

always favor users with good channel conditions
