窄带物联网上行资源调度的研究

In this paper, the related technologies of narrowband internet of things (NB-IoT) were researched. In terms of the features of uplink (UP)/downlink (DL) frame structure, multiplexing method and scheduling unit used by narrowband IoT(NB-IoT), the design schemes for resource scheduling, which is suitable for NB-IoT is proposed in this paper. This paper discusses the wireless network planning in NB-IoT system in the realization of the wireless resource scheduling, in addition to the use of wireless network planning software platform for NB-IoT system in three common resource scheduling algorithms for simulation. Based on the principle and characteristics of three resource scheduling algorithms, this paper shows the performance comparison and analysis of three algorithms in terms of cell throughput and fairness.
