Narrowband IoT Data Transmission Procedures for Massive Machine-Type Communications

摘要: Large-scale deployments of massive machine type communications involve several challenges on cellular networks. To address the machine-type communications, or more generally, Internet Things (IoT), 3GPP has developed Narrowband IoT (NB-IoT) as part Release 13. NB-IoT is designed to provide better indoor coverage, support a number low-throughput devices, with relaxed delay requirements, and lower energy consumption. reuses Long Term Evolution functionality simplifications optimizations. Particularly for small data transmissions, specifies two procedures reduce required signaling: one them based control plane other user (UP). In this work, we an overview these well evaluation their performance. The results consumption show both optimizations achieve battery lifetime extension than years large range in considered cases, up eight CP good coverage. terms cell capacity relative Service Request, achieves gains from 26 224 percent, UP ranges 36 165 percent. comparison yields similar results, except some specific configurations.
