摘　　要：目前中国联通LTE载波聚合已经在全国范围内部署,主要是基于竞争需求提升峰值速率,但是载波聚合存在激活比偏低的问题,整体使用效率不高。分析了影响载波聚合性能的因素,重点对辅载波激活策略进行分析,对不同辅载波激活门限的影响进行了分析与验证,并给出辅载波激活的参数设置建议。At present China Unicom LTE carrier aggregation has been deployed in the whole country,the peak rate is improved based on competition needs. The application of carrier aggregation technology has the problem of low activation ratio,and the overall efficiency is not high. It analyzes the factors influencing the performance of carrier aggregation,focuses on the analysis of the auxiliary carrier activation strategy,analyzes and validates the effects on different auxiliary carrier activation threshold,and gives suggestions and parameters of auxiliary carrier activation.
