摘　　要：在高密重载(用户密度高、业务负载重)场景,上行网络负荷高快速抬升LTE系统内上行干扰,严重影响用户感知.研究了上行信道质量恶化的因素,提出了一种有效改善上行信道质量的上行功率控制参数策略,并通过试点验证方案有效性.In high-density overload scenarios(high user density,heavy traffic load),the uplink network load rapidly increases the uplink interference in LTE system,which seriously affects user perception.The deterioration of the quality of the uplink channel was proposed,an effective uplink power control parameter strategy was proposed to improve the quality of the uplink channel,and the effectiveness of the scheme was verified through a pilot project.

关 键 词：TD-LTE 上行功率控制 高密重载 编码效率 上行干扰
