Embodiment Construction

[0039]The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] In the related art, when the beam tracking problem is solved by means of indirect beam tracking, it is often easy to cause the vehicle to have a high probability of communication interruption during beam switching because the beam setting is too narrow; In the beam control method, first, obtain the boundary information of the current beam serving the vehicle and the width value of the switching area, wherein the width value of the switching area refers to the size of the beam overla...

Abstract

The invention discloses an Internet of Vehicles V2I downlink beam control method, a medium, equipment and a device. The method comprises the following steps: acquiring boundary information and a switching area width value of a current beam serving a vehicle; acquiring driving state information of the vehicle, and calculating a distance value of the vehicle driving away from the current beam according to the driving state information and the boundary information of the current beam; judging whether the distance value of the vehicle leaving the current beam is less than or equal to the switchingarea width value; if the distance value of the vehicle driving away from the current wave beam is less than or equal to the switching area width value, starting the next wave beam; acquiring access state information of the vehicle, judging whether the vehicle accesses the next beam or not according to the access state information, and closing the current beam when the judgment result is yes. Themethod can effectively reduce the communication interruption probability of the vehicle in the beam switching process, improve the average data transmission rate of the system, and enhance the stability of V2I communication of the Internet of Vehicles.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a V2I downlink beam control method for Internet of Vehicles, a computer-readable storage medium, a computer device, and a V2I downlink beam control device for Internet of Vehicles. Background technique [0002] In the Internet of Vehicles scenario, most of the vehicles are in a state of high-speed movement when communicating, which leads to the continuous change of the positional relationship between the vehicle and the roadside infrastructure, and causes 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...
