摘要
进行了LTE-A移动通信系统中下行跨层分组调度机制的研究。提出了一种基于二维优先级的业务分组调度方法,该方法基于各类业务不同的业务特性与性能需求,计算二维优先级的三个决定参量:紧急系数因子、第一维优先级因子、第二维优先级因子。通过紧急系数因子、第一维优先级因子、第二维优先级因子及相应的影响因子系数和紧急指数的共同作用,实现了不同情况下各业务间的绝对优先级与相对优先级,达到兼顾系统有效性与业务Qo S满意度的目标。
The LTE- A system downlink packet scheduling mechanism is researched in this paper. A scheduling method based on two-dimensional priority is proposed. The method is based on all kinds of different service characteristics and performance requirements. And it realizes the absolute priority and relative priority among the various business, through combining emergency coefficient factor, the first priority factor, the second dimensions priority factor and the corresponding influence factor coefficient and index of emergency. This method achieved the Qo S satisfaction and system effectiveness.
