摘要
NB-IoT作为物联网的主要技术,以其容量低、覆盖广、成本低和低功耗等优点在智慧城市建设中扮演着重要角色。主要从频率部署、上行传输方案、上行链路帧结构和上行物理信道几个方面解析,以便让读者更了解NB-IoT技术的物理层上行链路。
As the main technology of Internet of things,NB-IoT plays an important role in the construction of smart city with its advantages of low capacity,wide coverage,low cost and low power consumption.This paper mainly analyzes the frequency deployment,uplink transmission scheme,uplink frame structure and uplink physical channel,so as to let readers know more about the physical layer uplink of NB-IoT technology.
