Abstract

Notable changes in the next-generation wireless communication system include the fact that the nominal height of base-station antennas becomes lower than the height of typical rooftops. In this scenario, reflection and scattering of waves become more dominant than diffraction in short-range propagation. We first analyze the reflection and scattering loss of propagation by using ray-tracing simulation, and on the basis of the analysis, we propose a propagation prediction model based on geometric optics in the urban street canyon scenario. The proposed model is defined by geometrical parameters such as the street width and the distance to a corner, such that the model can be applied to various environmental scenarios. It can also simultaneously predict propagation losses in many corners. The proposed model is justified with measurement data.
