中文摘要：

M2M通信是今后通信行业发展热点之一,因当前LTE具有覆盖范围广、运营成本低、支持向后扩展和系统容量高的特点,LTE必将成为未来M2M业务最重要的承载网络.通过分析M2M通信的业务特征,提出一种嵌入宽带中的窄带低功耗M2M通信设计方案;基于LTE TTI绑定机制提出了几种接收设计方案,以达到更深的覆盖范围;同时能够降低终端功耗和成本.通过搭建实际的软件和硬件平台,对提出的几种方案的性能进行了测试.结果表明：提出的方案相比LTE系统可获得17~21dB的覆盖性能增强.

英文摘要：

Machine-to-machine （M2M）communication is one of the hot topics in the current and future communication industry. With characteristics including wide coverage, low cost, backward compatibil- ity and high system capacity, Long term evolution （LTE） cellular networks would be an ideal platform for large M2M deployment. This paper analyzes the characteristics of the M2M communications and provides novel schemes to realize a narrow-band M2M communication system which is embedded in the current broadband LTE network. Such an M2M system has low power consumption and enhanced coverage. Furthermore, we propose several receiving mechanisms based on TTI bundling to achieve wider coverage, lower power consumption and less commercial cost. An actual hardware and software platform is established to test the suggested schemes. Simulation results validate that a 17 - 21 dB gain of the coverage performance can be achieved compared with the current LTE systems.
