Design of a UE-specific uplink scheduler for narrowband Internet-of-Things (NB-IoT) systems
2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG), 2018 Narrowband internet-of things (NB-IoT) is a 3GPP standard designed for Internet-of-Things (IoT) application. This paper presents the design consideration and possible options of a UE-specific uplink (UL) scheduler for NB-IoT system. We developed a unitary C emulation platform to verify the effectiveness of the proposed approaches, which is currently ...

Performance analysis of narrowband internet of things (NB-IOT)
, 2018 With the rapid development of NarrowBand Internet of Things (NB-IoT), the performance analysis of the NB-IoT system is more and more important. In this project, the NB-IoT narrowband physical downlink shared channel (NPDSCH) system is simulated in MATLAB. Four different operation modes (Inband-Same PCI, Inband-Different PCI, Guard Band and Stand-alone)
