摘要 分析了移动通信信道时变但仍然是连续变化的特点,提出了基于超前服务时间的功率节省调度算法。该算法使得用户都是在信道质量较好的一段时间内连续得到调度,在每个调度时隙块基站能够向用户传递更多的数据。仿真表明该算法流媒体播放质量保障能力和功率节省性能均有较好的表现。 This paper analyses the characteristic of the wireless channel, which is time-varying but also continuous-changing. An improved algorithm called ahead-service-based power-efficient scheduling is proposed, which keeps the user have good quality of channel when it is scheduled to increase the amount of effectual transmitted data.The simulation results show that it has good performance not only in QoS but also in saving power.
