| Abstract: | This paper studied some aspects of radio resource management for orthogonal frequency division multiplexing multiple access(OFDMA) systems with multimedia services supported,and presented an(opportunistic) fair scheduling algorithm of multimedia services.The algorithm is based on utilitarian fairness(UF).The simulation results show that the UF based algorithm can guarantee the proportional fairness of the throughput between every users,and evidently increase the total throughput of the system. |
