- 5G-NR radio planning for connected and autonomous vehicles servicesPublication . Teixeira, Grazielle Bonaldo; Serrador, António João NunesThe 5G network development is enabling many emerge technologies as connected and autonomous vehicles (CAV), promising a significant impact in the telecommunications industry in the future. In this thesis, was performed 5G radio planning by coverage and capacity, entirely when CAV applications are provided, requiring minimum and maximum user data rates according to different services categories from 5GMOBIX project. 5G air interface was explored joint to MIMO and modulation orders configurations, intending to analyse the different results in two diverse highways around Lisbon, for urban and rural propagation environments. Vehicles traffic model was simulated using real statistic numbers, aiming to compute more effective KPIs while the radio planning. The final number of sites calculated were compared regarding to each scenario simulated as well as the number of vehicles supported for each service category. The results showed that the cell ranges reached in DL were tens of kilometres, despite of some meters in UL for some network configurations. Also, the radio resources showed being enough when minimum user data rate is required, nevertheless when maximum user data rate is required, new cell and vehicle ranges recalculation were needed, reaching much higher number of sites due to the cell capacity limitation. The number of sites required in urban environment showed being the double when comparing to rural, due to the higher vehicles traffic.
