<p>In the age of 5G networks, vehicular communications are essential for providing efficient and reliable connectivity in urban areas. This study investigates vehicular communication technology in cooperative small cell networks. Cooperative small cell networks, consisting of base stations positioned near vehicular traffic, provide improved coverage, capacity, and reliability for mobile users, including both vehicles and pedestrians. In this paper, the system model for heterogeneous cell networks has been designed with small cells, macrocells, and microcells in vehicular communication. Cooperative probability and coverage probability are calculated analytically using stochastic geometry, for multiple antenna configurations and co-channel interference. The results show that the coverage probability of vehicular communication increases and outage probability decreases due to the cooperative behavior of small cell networks. Additionally, numerical results show that the suggested cooperative MIMO system performs better than non-cooperative models, in different path-loss scenarios and at high SINR thresholds. The analytical outcomes are further validated through extensive Monte Carlo simulations, ensuring the accuracy and robustness of the proposed approach. These findings offer practical insights for designing reliable and high-performance vehicular communication systems in 5G small cell environments.</p>
