| 摘 要： | 提出了基于未来无线多媒体通信标准下的一种跨层分组调度方案,在调度时,首先对多媒体混合业务进行了合理分类,即实时性业务和非实时性业务;在调度优先级的确定过程中,利用跨层优化的思想估算优先级公式中的相关参数,由此给出了跨层分组调度方案的具体算法流程.仿真结果表明,与传统经典的比例公平调度算法（PFS）相比,该方案在实时性、数据吞吐量、信道利用率等方面具有更好的性能.

| Abstract: | A cross-layer packet scheduling scheme is proposed under the standard of future wireless multimedia communications.In the scheduling,the multi-media business should be reasonably classified,that is,into real-time and non real-time business operations.In the scheduling process to determine the priority,a perspective of cross-layer optimization is used to estimate the relevant parameters of the priority formula,from which concludes the specific process of cross-layer packet scheduling algorithm program.The simulation results show that the program has a better performance compared to the classic and traditional fair scheduling （PFS） algorithm in time delay,data throughput and channel utilization, etc. |
