RECERCAT author Leon González, Daniel 2020-07-24 This TFM intends to explore the V2X communication capabilities for 5G systems, starting from the V2X sidelink defined in LTE Rel. 14 and including the most recent advances for 5G NR currently considered by recent release 16. The project targets to analyze the different simulation tools that are available for assessing the performance of V2X communications and to carry out a performance assessment of the technology.Vehicular communications are becoming a reality and are necessary to improve safety driving conditions. The objective of this thesis is to introduce the basic concepts of Cellular-V2X Mode 4 and analyze its performance in terms of channel busy ratio (CBR) and packet delivery ratio (PDR) under different scenarios and configurations. A C-V2X Mode 4 Simulator has been used to check the impact of different parameters such as the transmission rate, modulation and coding scheme, transmission power, subchannelization or probability of keeping the granted resources among others. Two different scenarios have been considered, a fast highway and a congested highway with low speed and high vehicle traffic congestion. The results have revealed relevant differences in terms of PDR between both scenarios. The main causes of failure, the delay and CBR have been also analyzed. The transmission rate is the parameter that most influences the overall performance of the network. In some cases such as the congested highway scenario, obtained performance has revealed some limitations of the technology, e.g. in terms of PDR... and it is expected that with the new capacities of 5G NR it could be improved.
