摘　　要：为了研究中国移动NB-IoT的部署策略,首先介绍了中国移动可以根据客户对速率的不同要求,提供三种物联网解决方案,即TD-LTE技术、e MTC技术、NB-IoT技术;然后从NB-IoT的帧结构、时隙结构、物理信道和扩展不连续接收模式等方面分析了NB-IoT的基本原理;最后提出了中国移动NB-IoT的部署策略,主要涉及上行子载波带宽的选择、操作模式的选择、频率使用策略、站址选择策略和建设方式的选择。In order to investigate NB-IoT deployment strategy of China Mobile, it was firstly introduced that three loT solutions, including TD-LTE, eMTC and NB-IoT, can be provided by China Mobile to customers according to their requirements for rate. Then, the principle of NB-IoT was expounded in temas of the frame structure, timeslot structure, physical channel and extended discontinuous reception mode. Finally, NB-IoT deployment strategy of China Mobile was put forward which deals with the uplink subcarrier bandwidth selection, operation mode selection, frequency usage strategy, site selection strategy and construction mode.
