Vehicle networking v2i downlink beam control method and device

Abstract

The invention discloses a V2I downlink beam control method, medium, equipment and device of the Internet of Vehicles, wherein the method includes: obtaining the boundary information and the switching area width value of the current beam serving the vehicle; obtaining the driving state information of the vehicle, and Calculate the distance value of the vehicle leaving the current beam according to the driving state information and the boundary information of the current beam; judge whether the distance value of the vehicle leaving the current beam is less than or equal to the switching area width value; if the vehicle leaving the current beam distance value is less than or equal to the switching area width value, Then turn on the next beam; obtain the access state information of the vehicle, and judge whether the vehicle is connected to the next beam according to the access state information, and close the current beam when the judgment result is yes; it can effectively reduce the vehicle's load during the beam switching process. Probability of communication interruption; increase the average data transmission rate of the system; enhance the stability of V2I communication of the Internet of Vehicles.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Vehicles, in particular to a V2I downlink beam control method for the Internet of Vehicles, a computer-readable storage medium, a computer device, and a V2I downlink beam control device for the Internet of Vehicles. Background technique [0002] In the Internet of Vehicles scenario, vehicles are mostly in a state of high-speed movement when communicating, resulting in constant changes in the positional relationship between vehicles and roadside infrastructure, and causing the V2I (Vehicle-to-Infrastructure) communication link of the Internet of Vehicles to be unstable or even disconnected. However, the transmission of safety and decision-making messages during vehicle driving has very high requirements on communication quality, and it is necessary to ensure the real-time and reliability of V2I (vehicle to infrastructure). The traditional millimeter-wave beamforming technology can n...

Problems solved by technology

The traditional millimeter-wave beamforming technology can no longer meet the needs of the Internet of Vehicles scenario. The high-speed movement of vehicles puts higher requirements on the millimeter-wave beamforming technology.

[0003] In related technologies, when the beam tracking problem is solved by means of indirect beam tracking, it is often easy to cause a high probability of vehicle communication interruption during beam switching because the beam setting is too narrow
