Recently, sharing perception sensor information among vehicles sets a higher transmission demand for vehicular communication. Facing the challenges, millimeter wave (mmWave) has the potential to realize multi-Gbps throughput transmissions. However, in conventional methods, beam sweeping is utilized in beam alignment, which is inefficient in high mobility scenarios. To overcome the drawback, this paper introduces vehicular position information into beam alignment in vehicle-to-vehicle (V2V) communication. Considering localization errors, in order to avoid beam misalignment, two beamwidth optimization methods are proposed to maximize the average throughput among the nearby region of receiver’s estimated position. Simulation results suggest that the proposed schemes provide appreciable performance improvements as compared to the traditional beam sweeping scheme.
