摘　　要：针对上行高速分组接入(HSUPA)技术中RNC外环功率的调整因素"HARQ失败"进行了研究,提出了一种通过合理设定虚警和漏警统计值门限来降低它们对HARQ失败上报影响的方法。实际系统测试表明,该方法很好地抑制了虚警和漏警对HARQ失败产生误报的影响,解决了由此造成的RNC外环功率控制和HSUPA调度器调度授权的稳定性和准确性问题。In order to solve the problem of faulse- report of HARQ- failure, depending on which RNC performs outside- loop power in HSUPA, a novel method for reducing the faulse- report of HARQ- failure by approximately adjusting the threshold of false- alarm and missing alarm is pro- posed. Practical experiment and system test indicate that the proposed method can effectively overcome the faulse- report of HARQ- failure resulting from the wrong faulse- alarm and missing- alarm,and this design can be used to improve the robustness and stability for RNC performing outside -loop power-control and for UE obtaining SG in HSUPA.
