摘要
在下行蜂窝网络中,多点传输计划因可以大幅度提高扇区平均吞吐量和小区边缘用户速率而越来越受到关注。传统的独立调度算法中参与多点传输的扇区分别调度各自的用户,这种独立调度算法限制了系统性能的进一步提高。文章提出了一种针对SF-DC HSDPA系统新的联合调度方案,基站间通过交换信息选择适合的传输方案,可更好地调度用户。通过系统级仿真结果可以看出,新提出的联合调度算法可以获得更好的扇区平均吞吐量和边缘用户体验。
In the downlink celluar network, multi- point transmission scheme becomes more and more popular, which can improve the average sector throughput and cell-edge users＂ rates largely. Tra- ditional scheduling algorithm limits the system per- formance improvement. In this paper, a new joint scheduling algorithm is proposed, which chooses the suitable scheme and schedules users jointly through exchanging information between the basestations. The system level simulation shows that the new pro- posed scheduling algorithm can achieve better aver- age sector throughput and edge users＇ experience.
