摘要

The fifth and beyond generations of communications (B5G/6G) aim to support massive connected objects and mission-critical applications. In the context of disaster management, the vehicles coordinating rescue operations in each area can also serve as local communication relays for the other participants. The evaluation of such applications at a city scale requires accurate modelling of both urban mobility and vehicular communications. Most works propose either analytical models providing a big picture of the performance expected in large-scale deployments, or real-world testing at a lower scale showing performance for concrete but limited scenarios. This paper proposes a simulation approach to the evaluation of 5G relay-empowered communications, which uses an event-based urban traffic modelling in order to accelerate large-scale simulations. It also uses propagation models designed from real-world measurements performed on mobile operators’ 5G infrastructure, which allows to envision the 5G communication performance that could be expected for applications such as cooperative localization and extended perception between the participating vehicles. The evaluations over a relay-empowered 5G network including one base station (gNB), 180 relays, and up to 350 vehicles in an urban city show that the relays improve downlink communications speed and end-to-end delay, while the gNB provides higher speeds in uplink communications overall. These evaluation results draw the performance expected from existing 5G deployments, and offer insight for communication management policy regarding the applications involved in rescue operations.
