The beam forming device of the present invention may feedback power-amplified signals to perform digital pre-distortion for improving the non-linearity of an analog element in a digital signal process terminal and control a phase for forming a beam. Therefore, the beam forming device that can form an accurate beam may be realized. | 10-02-2014 |
20140295826 | METHOD AND APPARATUS FOR CONTROLLING TRAFFIC NEXT GENERATION MOBILE COMMUNICATION SYSTEM - The present invention relates to a method and apparatus for controlling traffic which can be applied to the next generation mobile communication system. The method includes determining whether or not a load state of a cell is greater than a threshold, determining whether or not UE capable of D2D communication is present in UEs connected to the cell if, as a result of the determination, it is determined that the load state is greater than the threshold, performing a D2D communication configuration on the UE capable of D2D communication, determining whether or not UE capable of handover is present in remaining UEs not capable of the D2D communication, and performing a handover communication configuration on the UE capable of handover. According to the present invention, a signaling overload due to the simultaneous handover of a plurality of UEs or congestion of traffic in a target cell can be prevented. | 10-02-2014 |
