With the deployment of LTE system, im-proving the performance of edge coverage has be-come an important issue, which needs to be solved before large-scale commercial development. This pa-per introduces technologies related to coverage en-hancement in the LTE system, such as increasing signal transmit power and mitigating inter-cell inter-ference. In order to upgrade the LTE systems service quality and improve user satisfaction, various tech-nique should be selected according to actual network environment.
