LTE网络CRS功率配置及其影响研究

Study of CRS Power Configuration and Impact in LTE Network

为了解决速率和覆盖之间平衡的问题,通过深入分析CRS的3种配比的原理,并结合现网数据分析验证不同配比对网络KPI和MR指标的影响,提出在不同场景下调整不同的CRS功率配置,使得速率和覆盖达到一个相对均衡状态。经过功率配比现网数据分析验证,与分析结果一致,CRS在不同场景下的不同配比能够提升网络性能,从而保证用户的良好感知。

In order to balance rate and coverage, this paper analyzed the principles of the three different configurations of CRS, combined with the current network data, influence of CRS different proportions on network KPI indicators and MR was analyzed and verified. It is proposed that at the different scenarios, adjust the CRS different configuration to achieve a balance of the coverage and rate. After the power configuration network data analysis and verification, which is consistent with the analysis, the CRS different configuration in different scenarios can improve network performance, and ensure a good perception of the user.
