To efficiently perform millimeter wave communication between vehicles.SOLUTION: A method for executing beam alignment among a plurality of vehicles which perform millimeter wave communication includes: a reception step which receives, in a second vehicle, a radio message which includes first vehicle data indicative of the position and the driving intention of a first vehicle; a prediction step which, based on the driving intention and the position of the second vehicle and the first vehicle data, predicts whether interception occurs between the first vehicle and the second vehicle; a route determination step which, based on the driving intention and the position of the second vehicle and the first vehicle data when the occurrence of the interception is predicted, determines an NLOS path which is a propagation path for the first vehicle and the second vehicle to perform millimeter wave radio communication in the non-line of sight range; and an adjustment step which executes the beam alignment between the first vehicle and the second vehicle by the NLOS path.SELECTED DRAWING: Figure 1
