Radio Resource Management Methods for Ultra-Reliable Low-Latency Communications in 5G LTE Narrowband Industrial Internet of Things

We proposed the architecture of the 5G LTE/Narrow Band Industrial Internet of Things (NB-IIoT) network for providing real time IIoT services by allocating the narrow bandwidth spectrum and transferring some functions over the eNodeB base station to the IoT controller. This method takes into account the priority of IIoT traffic and by scheduling resources on the new IoT controller allows to leave the existing eNodeB base stations unchanged. For the first time the method of IIoT traffic prioritization is proposed, on the basis of which the modified algorithms for planning and allocating radio resources in the IoT controller are developed. The method of load balancing for 5G LTE/NB-IIoT networks was developed. The proposed methods take into account the priority of IIoT service and provide Ultra-Reliable Low-Latency Communications (URLLC) for real time IIoT services in 5G networks.
