摘要:

针对无线接入网中由于各种故障造成的小区通信链路中断问题和时分-同步码分多址(TD-SCDMA)无线通信系统上、下行链路具有相同链路增益的特点,提出了一种基于上行目标接收功率开环功控的分布式TDSCDMA高负载小区中断补偿算法.通过预先定义边缘用户质量目标,采用上行功控迭代算法自动调整邻小区上行目标接收功率,从而增加覆盖范围,达到最大程度地补偿中断小区覆盖空洞的目标.仿真结果表明,该算法收敛速度较快,在给定的场景下有78%的中断用户重新与网络建立了连接.

Abstract:

 For cell outage problem due to various faults in wireless access networksan distributed time division-synchronous code division multiple access (TD-SCDMA) high load cell outage compensation algorithm is presented based on uplink target receiving power adjustment in open loop power control. In the presented algorithm, the parameters of cells neighboring failed cells can be automatically adjusted such that the coverage is maximized the given constrains on quality defined by cell-edge user throughput. Simulation shows that up to 78% of the user can be recovered at the cost of an acceptably reduced quality in the compensating cells.

Key words:  cell outage compensation, uplink target receive power, power control iteration, time division-synchronous code division multiple access
