Beam tracking method and device, base station and computer readable storage medium

The invention discloses a beam tracking method and device, a base station and a computer readable storage medium. The method comprises the steps: building an adjacency list according to the initial correlation between beams; according to the adjacency list, determining a first type of correlation beams whose correlation with the current optimal beam is greater than a first threshold value; scanning a current optimal beam and a first type of related beams; circularly scanning the beams in the adjacency list from the first type of related beams; determining the correlation of any two scanned beams and updating the adjacency list according to the received signal quality of the scanned beams fed back by the receiver; and according to the updated adjacency list, determining whether beam deviation exists and re-determining the current optimal beam. By adopting the method and the device, the optimal wave beam can be tracked in real time, and the wave velocity is scanned according to the correlation between the wave
