Since the evolving standardization of cellular V2X (C-V2X) technologies is continuously developed by 3GPP, research on new radio (NR-V2X) has been on schedule by academic and industries. Though millimeter wave (mmWave) frequency band is supposed to provide large transmission bandwidth, yet the development of mmWave band in NR-V2X is still in preliminary stage. In this article, a comprehensive discussion of mmWave NR-V2X is given covering trends, standardization landscape, and enabling technologies, aiming at tackling the challenge of channel modeling, directional channel access, beamforming and blockage management. The vision of mmWave NR-V2X is to fully support the development of automated driving, holographic control display and improved in-car infotainment for the future.
