High-speed mobile terminal beam scheduling method based on beam sharing

The invention belongs to the technical field of beam modulation, and discloses a high-speed mobile terminal beam scheduling method based on beam sharing. The method comprises the steps: collecting historical positioning information with positioning errors of a user group in a training process of an initial access process, obtaining a high-probability position of the user group in a speed and positioning error range through a result of a speed state and position information of the user group, and performing scanning matching with each beam coverage range of a base station, and sending beams to the user group, wherein the beam matching priorities are ranked according to the beam matching accuracy; in a beam sharing stage, utilizing the beams of each user group obtained in the first stage to obtain an interference relation matrix among the beams; according to the descending order of the interference relation matrix values, combining the beams with the interference relation, and updating the beam width of the com
