| 摘 要： | 长期演进系统(long term evolution,LTE)中的分组调度算法需要满足一定的QoS.针对最大权值时廷优先算法(modified large weighted delay first,M-LWDF)在用户公平性方面的缺陷,提出了基于线性优先级和非线性优先级的M-LWDF算法,以达到提升用户公平性的目的.仿真结果表明,所提出的算法能够在牺牲少量系统吞吐量的情况下,较大程度地改善用户公平性和业务的丢包率. |

| Abstract: | In LTE system, the QoS should be satisfied by packet scheduling algorithm. To improve the fairness between users in the algorithm of modified large weighted delay first (M-LWDF), two novel packet scheduling algorithms are proposed in this paper, linear and non linear priority adjusting scheme respectively. Results show that the performance of user fairness and packet loss ratio can be improved effectively; moreover, only very little network resources will be consumed. |
| Keywords: | long term evolution (LTE) quality of service(QoS) modified large weighted delay first (M-LWDF) |
