| 摘 要： | 为提高资源分配过程中不同速率需求的用户间公平性，结合正比公平算法，提出一种应用于第三代合作伙伴计划长期演进系统上行链路的分组调度算法。算法按照不同用户的速率需求分配资源，并在每次调度过程中使用动态变化的权重因子，避免出现速率需求高但瞬时信道状况差的用户分配过多的资源。仿真结果表明，该算法相对于正比公平算法更好地解决了不同用户间的公平性。

| Abstract: | To enhance fairness between users with different data rate requirements in resource allocation process, this paper extends the proportional fair (PF) algorithm, proposes a packet scheduling algorithm for the third generation partnership project (3GPP) long term evolution (LTE) uplink systems. The algorithm allocates resources to users according to their data rate requirements. The weight factor in the algorithm updates in every scheduling process, so that users with high data rate requirement but in bad instantaneous channel state will not be allocated excessive resource. Simulation results show that the proposed algorithm has a better performance in fairness between different users than PF algorithm. |
