NB-IoT深度覆盖特性及网络性能评估体系研究

Research on the In-Depth Coverage Characteristic and the Network Performance Evaluation System for NB-IoT

为了对NB-IoT网络建设性能进行评估,本文对提高深度覆盖采用的功率谱密度提升、上下行物理信道重定义、重传机制等技术进行了研究分析,针对这些技术特性设计网络性能评价指标实现方法,总结物联网与LTE网络性能评估体系差异。

In order to evaluate the performance of the NB-IoT network, the techniques to enhance the in-depth coverage including the power spectral density enhancement, up/down link physical channel redefinition and retransmission mechanism were investigated. The implementation methods of the network performance evaluation metrics according to the technical characteristics were designed. The difference of the network performance evaluation system between the loT and the LTE was summarized.
