In this work, a recently conducted measurement campaign for millimeter wave (mm-wave) vehicle to vehicle (V2V) propagation channel characterization is introduced. Two vehicles carrying a transmitter (Tx) and a receiver (Rx) respectively were driven towards each other at an average speed of 60 km/h in an urban area of Jiading District, Shanghai, China. The measurement was conducted with 409.6 MHz bandwidth at center frequency 73 GHz. The parameters investigated include the large-scale fading and small-scale fading coefficients. Specifically, a 2-slope path-loss model was proposed. Six kinds of distributions of analytical expressions were used to fit the fast fading distribution. The results show that the fast fading distribution changes from Rician to Nakagami, finally to lognormal with the distance between the Tx and the Rx increases.
