针对LTE系统无线信道的复杂性和用户上行信道估计的不准确性,结合上行信道的实际情况,对经典PF调度算法进行改进,提出一种基于惩罚因子的LTE上行调度算法,并采用该算法对GBR业务进行上行调度仿真。实验结果表明,该算法在仿真网络环境下能有效提升LTE网络的上行业务量,提高网络资源的利用率。

In view of the complexity of the wireless channel and LTE system inaccurate uplink channel estimation, Classical PF schedule is improved to adapt uplink schedule algorithm in this paper, and a new uplink schedule algorithm is proposed based on Penalty factor. The proposed uplink schedule algorithm is demonstrated with GBR traffic by simulation of OPNET platform. The result of simulation proves that the new algorithm can improved the up- link throughput of LTE system, the utilization of wireless resources can also be improved.
