RADIO BASE STATION, VEHICLE COMMUNICATION DEVICE, AND MOBILE COMMUNICATION METHOD

Title:

RADIO BASE STATION, VEHICLE COMMUNICATION DEVICE, AND MOBILE COMMUNICATION METHOD

Document Type and Number:

Japanese Patent JP2022118990

Kind Code:

A

Abstract:

To provide a mobile communication system capable of performing reliable communication.SOLUTION: A leading vehicle transmits a CSI estimation value associated with positional coordinates of an observation spot to a following vehicle using vehicle-to-vehicle communication. An own vehicle, as the following vehicle, compares CSI at a certain spot provided from the leading vehicle with CSI at the same spot calculated by the own vehicle to calculate a difference between an antenna characteristic of the leading vehicle and that of the own vehicle. In a state in which the antenna characteristic difference can be calculated, beam control is performed using the antenna characteristic difference and CSI of respective spots that is provided from the leading vehicle at any time.SELECTED DRAWING: Figure 1
