The millimeter-wave band communication system implements a sharp beam through a massive antenna array to mitigate extreme path attenuation. The beamforming gain required for communication can be satisfied by performing beamforming in the corresponding direction if the position and direction of the target are accurately given. However, the beam alignment based on narrow beams may be vulnerable to angular noise caused by movement, and wobbles of the aerial target. Beam misalignment degrades communication link quality and occurs a fatal effect on communication performance, such as packet loss. In this paper, we propose beam pattern design scheme to maintain a reliable link quality by predicting the angle for the next time frame from the control signals.
