A reliable Vehicle-to-Vehicle (V2V) communication system is particularly important for intelligent transportation systems (ITS), and high-data-rate transmission is required for future V2V systems with the increase of vehicular sensors. In addition, an important V2V scenario, parking IoT, is ignored by researchers. In this paper, V2V 41GHz millimeter wave (mmWave) channel measurements are conducted in both underground and open parking IoTs for the first time. The received signal strength indication (RSSI) and channel impulse response (CIR) data are obtained by using the time domain measurement method based on Golay complementary sequences. Large- and small-scale fading characteristics, such as path loss, shadow fading, Root mean-square delay spread (RMS-DS) and Ricean K factor, are analyzed. The channel characteristics of underground parking IoT and open parking IoT are compared. The measurement and analysis results are useful for the design and channel modeling of mm Wave V2V systems in parking IoT scenario.
