Proposal on Propagation Prediction Method Based on Dynamic Channel Properties for High Frequency Bands in Urban NLOS Environment

This paper proposes an improved propagation prediction method that incorporates a vehicle model and building model in an urban non-line-of-sight (NLOS) environment for high frequency bands above 6 GHz in fifth generation mobile communications systems. We applied the models to a previously developed hybrid method that employs ray tracing and an effective roughness model. We found that the results using the proposed improved prediction method assuming the vehicle shielding probability of 50% exhibit a similar tendency to measurement results in urban NLOS environments.
