Channel model for millimeter-wave communications based on geometry statistics

High frequency band millimeter wave (mmWave) communication is expected to be one of the key components for 5G wireless communications system. In designing the new air interfaces for mmWave, understanding the channel is a fundamental step. In this paper, we look into the key characteristics of the high frequency band channel and present a channel modeling framework based on geometry statistics. The proposed channel model lies between a fully statistically channel model and a ray-tracing based channel model and captures the key channel characteristics. Numerical results show a good match of the channel model with measurement results.
