A multi-gigabit (WiGig) system is designed based on IEEE 802.11ad standards by exploiting millimeter-wave (mmWave) bands to achieve extremely high data rates. IEEE 802.11bd and 3GPP NR V2X are two new specifications for the next-generation vehicle-to-everything (V2X) network with the capability to support mmWave bands. However, mmWave bands could be the solution for the high throughput and low latency. Still, the instability of blockages is a substantial challenge in mmWave bands, rendering mmWave ineffective in vehicular networks. Typically, technologies capable of operating at mmWave bands, such as IEEE 802.11ad, IEEE 802.11bd, NR-V2X, etc., share the same technical limitations due to the mmWave characteristics. Therefore, to achieve the aspirations of next generation connected mmWave V2X vehicles. In this paper, we propose classic, cooperative, and extension protocols for IEEE 802.11bd by enhancing IEEE 802.11ad. The proposed solution aims to mitigate some of the most common technical challenges associated with using mmWave bands in V2X networks, such as beam training overhead, link blockage, and limited coverage range. Simulation results demonstrate that the proposed approach effectively reduces the beam training overhead, overcomes link blockage, increases the probability of line-of-sight (LOS), and extends the coverage range. Further, the proposed enhancement achieves significantly higher performance against the conventional solution and shows more link stability despite continuous changes in vehicle density.
