Abstract: The disclosure includes implementations for determining a position of a vehicle using millimeter wave narrow beamforming. A method may include receiving a set of training packets that each uniquely identify a position on a portion of a roadway where the vehicle is located. Each of the training packets included in the set may be associated with only one of the millimeter wave narrow beams. The method may include identifying a training packet included in the set of training packets that has a highest receive power level among the set of training packets. The method may include determining the position uniquely identified by the training packet having the highest receive power level. The method may include determining positional information for the vehicle based on the position uniquely identified by the training packet having the highest receive power level. The positional information may describe a location of the vehicle on the roadway.
