LTE覆盖增强技术概述

Coverage Enhancement Technology in LTE System

随着LTE系统的不断部署,系统边缘覆盖能力的提升已成为大规模商用化之前亟待解决的重要问题。介绍了LTE产业化过程中覆盖增强的相关技术,主要通过增加数据的发射功率和抑制小区间干扰来实现LTE系统的覆盖增强。各种技术的使用需要根据实际组网的环境灵活选择,可以有效改善LTE系统的上下行覆盖质量,提高用户满意度。

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 increasin 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.
