Bibliography:In this paper, the feasibility of using Massive MIMO technology to transmit NB-IoT information is validated. First of all, this paper summarizes the current situation of NB-IoT, the difference with LTE and the problems encountered in the current devel- opment process. Secondly, the signal transmission process and system structure of Massive MIMO technology are explained. Finally, the experiments demonstrate that Massive MIMO technology can be used for NB-IoT by simulation to achieve the goal of extending battery life, increasing coverage, and increasing support for nodes.
