摘　　要：接纳控制是TD-SCDMA系统无线资源管理中一个重要方面,它建立在对各小区负荷的测量基础之上,因此,小区负荷的计算方法成为一个十分重要的研究问题。由接纳控制和小区负荷等概念入手,提出小区上、下行负荷估计算法,上行负荷算法基于对噪声恶化量的控制,因该值能很好的衡量系统的干扰状况;下行负荷算法主要参考基站发射的总功率,有着直观的物理意义。进一步分析了邻小区干扰与小区负荷之间的关系,为网络的优化提供了理论依据。相关重要变量关系做了仿真,算法得到验证。As one of the important aspect of RRM(Radio Resource Management) in TD-SCDMA system, CAC is based on the measure of burden on a cell, so find a method to reckon the burden on a cell become important. Start with concept of CAC ,burden on a cell and so on, algorithms which used to recon burden on Uplink and Dwlink is proposed . Algorithm for Uplink based on the control over noise rise, it can be effective to measure interference in system; Algorithm for Dwlink come from the total power of BS, which has a intuitionistic meaning. The relationship between the cell and adjacent cells is being analyzed furthermore, provide a theoretic basis to the optimization of network . Several important simulation results over important variables are provided to verify the algorithms proposed in this paper.
