With the development of vehicular networks, spectrum resources are becoming increasingly scarce, and improving spectrum efficiency (SE) has become more and more important. Compared with common half-duplex (HD) technology, wireless full-duplex (FD) technology can effectively improve SE. Therefore, in this paper, we introduce FD into vehicle-to-vehicle (V2V) links, investigate the problem of spectrum resource reuse in vehicular networks, and realize the reuse of FD V2V links for the spectrum occupied by vehicle-to-infrastructure (V2I) links. At the same time, we also adopt a multi-agent deep reinforcement learning method to solve the problem that the rapid changes in the vehicular environment. The simulation results show that under 120 dB self-interference cancellation, the transmission rate of FD V2V links is significantly improved compared with that of HD V2V links.
