Description
Summary:This paper is proposing the integrated use of UWB and 5G localizing technologies in the Smartphones to optimize user experience. In use cases where high volume and lower latency are needed, using the NR-sidelink and the newly proposed Multiple QoS class in 5G is shown to be highly effective. The overall signalling overhead and latency reductions are demon-strated through system level simulations. We propose to group users into clusters, aided by the intrinsic group behaviour in these use cases and then to employ the NR-sidelink for ranging users within a cluster. We provide details of the mobility model and the performance of the user clustering algorithm within this model. We also develop LPP (LTE Positioning Protocol- also adapted for 5G) compliant simulations and use the new Multiple QoS class to show reductions in latency. While the UWB and 5G based localization are currently developing as separate technologies, this paper explores application areas where the integrated use is highly beneficial.
