针对现网LTE在CQT过程中MR无下行信号与干扰加噪声比SINR测量值而导致网络干扰分析难度大的问题,文章提出一种基于参考信号接收质量(Reference Singnal Received Quality, RSRQ)的LTE无线网络干扰分析算法。该算法利用RSRQ和SINR的基本性质,构建两者的数学关系式,以达到利用MR数据分析LTE网络干扰的目的,提高了LTE无线网络优化工作效率。结果表明,该算法在实际应用中存在一定偏差,经过矫正后与实测结果基本吻合,从而验证了该算法在网络优化应用中的可行性。

For the LTE Call Quality Test(CQT) process measurement report(Measurement Report, MR) without downlink Signal to Interference plus Noise Ratio(SINR) measurement value, which makes the network interference analysis difficult.This paper proposes an LTE wireless network interference analysis algorithm based on Reference Signal Received Quality(RSRQ). The algorithm uses the basic properties of RSRQ and SINR to construct a mathematical relationship between the two to achieve the purpose of using MR data to analyze LTE network interference. And it improves the efficiency of LTE wireless network optimization. The results show that the algorithm has a certain deviation in practical application, and it is basically consistent with the measured results after correction, which verifies the feasibility of the algorithm in network optimization applications.
