Performance Evaluation of Multi-Connectivity for Massive-URLLC in Emergency Scenarios

The integration of advanced communication technologies is crucial for enhancing public safety solutions, especially in emergency scenarios. Ensuring reliable and resilient communication is essential for both civilians and first responders during such critical situations. Multi-connectivity is one of the key techniques to enhance the robustness and reliability of communication systems in the context of ultra-reliable and low latency communications (URLLC), although it requires network resources, specially in the presence of massive number of devices. This paper investigates the use of multi-connectivity in the context of massive-URLLC use cases in emergency situations. By integrating packet duplication within multi-connectivity, we aim at providing a robust communication framework capable of guaranteeing a required level of massive connectivity during critical situations. We conduct comprehensive simulations to compare the performance of multi-connectivity against single connectivity, focusing on key metrics such as block error rate and bit error rate under varying network conditions and signal-to-noise power ratio thresholds. Our results demonstrate the potential of multi-connectivity by highlighting operating conditions in which a significant improvement of network reliability and performance in emergency scenarios is achieved.
