Abstract

The support of mission-critical use cases is an ambitious goal of the upcoming fifth generation of mobile networks. In addition to challenging requirements regarding reliability and latency, particular use cases need to be supported in high mobility scenarios as well. To avoid extensive system simulations and enable studies of very small outage probabilities, we integrate mobility effects into an existing signal-to-interference- plus-noise ratio (SINR) model by combining the model with results from a mobility simulation. An evaluation of the model corroborates that high mobility can severely deteriorate the reliability performance in traditional single-connectivity architectures. As potential countermeasures, inter- and intra-frequency multi-connectivity are identified. Results show that high reliability of 99.999% or greater becomes possible if a sufficient number of connections is utilized.
