Narrow Band Internet of Things(NB-IoT)is a promising low-power Wide-Area Network(WAN)technology.Communicating a small amount of data over a long period of time is one of the goals in the NB-IoT,which is one of the key features in the IoT application.Some research groups have defined several NB-IoT standards,such as low power consumption,wide coverage,large capacity,and low cost.Compared with the conventional wireless communication protocol,NB-IoT spectrum bandwidth is only 180 kHz.Therefore,how to use resources or spectrum more effectively(i.e.,resource allocation and scheduling)is a key issue.In this paper,we first design the upper layer communication of the physical layer,especially the uplink scheduling.Then,we discuss the resource allocation of NB-IoT in the case of good delay.Finally,we discuss some open problems and their corresponding solutions,which ensure the reliability of signal transmission.
