Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The terminal device predicts future beam measurement values before actual beam handover is needed. By performing preliminary prediction of beam quality changes based on current measurement values and movement state, the system proactively identifies beams that will become optimal, preventing sudden communication rate drops and reducing frequent beam handovers.
