【Abstract】 In this paper, the trade-off algorithms between the cell throughput and the cell edge user data transmission rate are dealt with for radio resource allocation in the next generation mobile communication system. By adopting inter cell interference coordination and power control algorithms, fairness is also introduced to equalize the spectrum utilization and system fairness. Meanwhile, simulation results show that, compared with traditional PF algorithm, the renewed algorithm(TFI-PF) can effectively improve system performance, which increases the cell throughput and improves user fairness with a trade-off between the spectral efficiency and system fairness.更多还原
