摘要: 以第三代移动通信系统的长期演进(LTE)标准为背景,针对上行调度中资源分配算法展开研究,分析公平正比(PF,Proportional Fair)调度算法的优缺点,并提出一种补偿公平正比调度算法。该算法可以判断用户当前分配的RB资源的服务质量好坏,对服务质量较差的RB资源进行重新分配。仿真分析表明,本算法可以在系统吞吐量和用户公平性之间取得较好的平衡。

Abstract: As the LTE standard of the third generation of the mobile communication system being its background, this paper carries out a research on the arithmetic of resource distribution for LTE uplink. It makes an analysis and comparison of advantages and disadvantages of the arithmetic proportional fair, puts forward a complementary proportional fair transposition arithmetic, which can judge the service quality of the RB resource currently distributed to the user and re-distribute the RB resource which is of a lower quality. The simulation shows that the complementary transposition arithmetic is able to seek a favorable balance between the throughput of system and user equity.
