Abstract
The measurement report (MR) contains key information such as the received signal strength of the user terminal in the network, which can reflect the coverage and interference of the LTE network. With the advantages of low cost, large amount of data and high reliability, measurement report has been widely used in practical network optimization. In this paper, a centralized distribution area of weak coverage sampling points is obtained based on the MR and combined location information from the actual users in network. Through the continuous iterative adjustment of antenna parameters, the optimal setting of antenna horizontal direction and vertical down-tiltangle are found, which can optimize the coverage performance of the entire cell. In order to verify the performance of the antenna optimization algorithm in this paper, at the end of the paper, the application effect of the scheme in the practical network is given. Through the verification, the optimization scheme proposed in this paper can effectively improve the coverage performance of the weak coverage cell.
