AI Technical Summary

Technical Problem

Existing beam prediction technologies in vehicle-to-everything (V2X) communication fail to adequately consider the impact of dynamic objects, resulting in inaccurate beam prediction results and consequently affecting the stability of the communication link.

Method used

By working together with terminal and network devices and combining the occlusion conditions of dynamic and static objects, beam prediction is performed, including sending vehicle information, location information, link quality information, and information on non-networked vehicles that are obstructing the network, and generating instructions for terminal devices to switch beams or interrupt the beam.

Benefits of technology

It improves the accuracy of beam prediction, enhances the link stability of vehicle-to-everything (V2X) communication, and reduces the risk of beam failure and interruption.

Abstract

Embodiments of the present application provide a communication method and device, relating to the technical field of communication. The method can combine dynamic objects and static objects to predict the beam of the terminal device, thereby improving the accuracy of beam prediction and improving the link stability of vehicle networking communication. The method comprises: sending first information, the first information comprising vehicle information, position information and link quality information of the terminal device. The vehicle information is pre-set in the terminal device. Trajectory information is sent, the trajectory information comprising at least one position information of the terminal device within a first time length in the future. Third information is sent, the third information comprising information of at least one non-networked blocking vehicle, the blocking vehicle being capable of blocking the communication beam used by the terminal device. A first indication is received, the first indication being used to instruct the terminal device to perform beam switching or beam interruption. The first indication is generated by the network device according to the first information, the trajectory information and the third information.
