APPARATUS OF TRX BEAM SELECTION FOR THE MOBILE USER EQUIPMENT USING MULTIPLE DIRECTIONAL ANTENNA

摘要

According to the present invention, a motion calculation circuit periodically tracks a posture changing value of a terminal and tracks whether the posture changing value is changed to exceed a threshold value set in accordance with a configuration of the terminal. The threshold value is basically set in accordance with the number of terminal antennas. Assuming that 360° horizontal omni-direction is divided and charged by n antennas, one antenna is in charge of 360/n wherein the threshold value is +-360/2n.
