摘　　要：以LTE与2G/3G系统共站建设为出发点,分析了不同频段LTE系统的覆盖能力,研究了MIMO、IRC等多种覆盖增强技术的适用场景和增益。以满足设定的上下行速率需求和上下行覆盖平衡的要求为标准,给出了各项覆盖增强技术的阶段性引入的建议。Underlying assumption that LTE will be deployed reusing the sites of 2G/3G systems, the coverage performance of LTE with different carrier frequency is analyzed. Subsequently the application scenarios and related gains of MIMO, IRC, ect are dis- cussed. Finally to satisfy the given downlink/uplink rate requests and the demand of coverage balance of downlink and uplink, the suggestions of phased deployment of coverage enhancement technologies in LTE are provided.
