摘要 基于移动台的位置信息,提出了基于移动台与基站之间的距离信息的多用户调度算法.针对特定的信道模型,分析了所提出的调度方法所需的吞吐量、反馈开销以及计算复杂度.理论和仿真结果表明:该调度方法所需反馈量明显降低且其所需计算量明显小于基于最大信干噪比的调度方法. A multiple-user scheduling scheme is proposed based on the position between the mobile station (MS) and the base station (BS). Throughput, feedback load and computing complexity are all derived for the proposed scheduling method. Analysis and simulation results demonstrate that the feedback load and computational complexity are both cut down compared with the maximum SINR based scheduling method.
