Channel Characterization for mmWave V2I Communication in Urban Scenario

In Intelligent Transportation Systems (ITS), vehicle-to-infrastructure (V2I) communication is one of the most important modes. Both ultra-reliable low latency and high-data rate communication are required in the V2I network. In this paper, extensive ray-tracing (RT) simulations are conducted to characterize the channel for mmWave V2I communication in typical urban scenarios in 22-23.6 GHz. Based on the RT results, the path loss, root-mean-square (RMS) delay spread, and the Rician K-factor of the channel are characterized, which guide the design and deployment of V2I communication systems.
