NB-IoT is a key construction network of the current operators. Its development prospect and application requirements are also constantly expanding. Among them
low power consumption is one of the most important technical features of NB-IoT
and application of the important factors. Based on the introduction of the NB-Io T network architecture and the main technologies
this paper focuses on NB-IoT power control methods and how to achieve low power consumption
and analyzes the infl uencing factors and parameters to make recommendations for NB-IoT network power control.
