Design of A Collaborative Ranging Aware UE Aggregation Transmission Mechanism for Future IoT Networks

With the evolution of wireless communication ser-vices, the requirement for reliability and latency is more and more strict, especially in the field of personal consumption area and the Industrial Internet of Things (IIoT), such as autonomous vehicles, remote healthcare, smart factory, augmented reality (AR)/virtual reality (VR), and so on. Moreover, the requirement for reliability and latency is also diverse for different types of communication services. Under the requirement of the enhancement of such hyper reliability and low latency communications (HRLLC) and the fact of diver user equipment capabilities, this paper proposes a collaborative ranging aware UE aggregation transmission mechanism for future IoT networks. Under the proposed mechanism, a ranging aware scheduling (RAS) based commu-nication procedure is designed for reliability enhancement and latency reduction, wherein some UEs or particular higher-end devices play as cooperation nodes (CNs) for packet duplication through multiple paths simultaneously. Considering each CN's system signaling overhead and signal processing capability with a restriction of latency requirement, the scheduling algorithm RAS is performed at each CN. According to the presented simulation results, the research work in this paper can provide insight into the distributed cooperation system for future IoT networks.
