User equipment beam effectiveness
Systems and methods are provided for improving user equipment (UE) beam effectiveness for a high mobility user. The system calculates at least one shift value for a UE based on a reference signal transmitted by the UE. When it is determined that the at least one shift value for the UE is greater than a predetermined threshold, the system will analyze at least past shift value. Based on this analysis, the system will predict a future shift value for the first UE beam. Then, instruction are provided for the modification of one or more of a first UE beam or a second UE beam.
