In this paper, the setup, scenario and first results of a measurement campaign on 28 GHz high-speed train backhaul channels are presented. The measurements were performed in a rural propagation scenario. Both large-scale measurements with a moving receiver and angle-resolved measurements with a static receiver at various positions were conducted to thoroughly characterize the environment. A novel virtual circular array antenna was employed to capture the angle-of-arrival information. The results show that the estimated angles correlate well with the environment. A path loss model for line of sight is parameterized and RMS delay and angle spreads are evaluated. The comparison with the 3GPP TR38.901 channel model parameters shows that the evaluated spreads are smaller that the 3GPP values but of the same order of magnitude as the values for the urban micro scenario.
