| 摘 要： | 基于基站的总接收功率反映了该小区和周围小区上行链路的业务负载情况的原理,提出了宽带码分多址系统中的一种业务负荷动态分配算法。中心小区基站根据上行链路的总接收功率周期性地调整导频信号的发射功率,使得移动台在中心小区和周围小区平滑切换,从而实现业务负荷的动态分配。仿真结果证明,该算法获得了较好的效果,有效地改善了上、下行链路的呼叫阻塞率和中断掉话率。

| Abstract: | The total power received in Base Station(BS) reflects the situation of traffic load in uplink in central cell and adjacent cells. Based on this principle, a dynamic distribution scheme of traffic load in WCDMA system is proposed in this paper. The central Base Station( BS) periodically adjusts the power of pilot signal according to the total power received in uplink. Mobile Station(MS) is able to hand off between central cell and surrounding cells smoothly, so the dynamic distribution of traffic load is realized. The results of simulation indicates that this scheme can get good performance, the block probability and the dropping probability in uplink and downlink can be improved. |
