The mmW4Rail project explores the millimeter wave band for train-to-train and train-to-infrastructure communications. It involves the definition of new channel models based on measurements in railway environments in the 60 GHz and the design and integration of specific antennas. The Doppler shift due to high train speed requires a specific design of the beamforming codebooks and the channel state information feedback mechanism. In addition, new solutions for radio resource management will be proposed. The performance will be assessed via system level simulations integrating the measurements-based channel model, antenna and beamforming design. This paper will focus on some preliminary results related to channel characterization and enhancement of the communications thanks to system level simulations. |
