基于PRB随机化策略研究提升CQI高阶占比

Research on PRB Randomization Strategy to Improve CQI Higher Order Ratio

针对非全带宽干扰引起的CQI高阶占比较低小区,可以采用PRB随机化策略,尝试通过修改干扰小区的上下行PRB偏置,在调度资源过程中,优先调用非干扰频段RB,以实现提升KPI指标,提升CQI高阶占比水平。

For the cells with high CQI and low order caused by non-full bandwidth interference,you can use the PRB randomization strategy to try to modify the uplink and downlink PRB bias of the interfering cell.In the process of scheduling resources,the non-interfering frequency band RB is preferentially called to improve The KPI indicator improves the CQI high-order proportion.
