| 摘要 |
<p>The present invention relates to a cell configuration modification method to apply a simultaneous transmission method during a carrier aggregation operation, a mobile communications system executing the method, and a digital signal processing device thereof. The system includes: a digital signal processing device which is connected to the core system and processes wireless digital signals; and multiple wireless signal processing devices which convert and amplify the digital signals transmitted from the digital signal processing device to transmit the signals to a terminal and receive the signals transmitted from the terminal to deliver the signals to the digital signal processing device. The digital signal processing device modifies the second cells conducting the carrier aggregation operation as main cells to apply the simultaneous transmission method to the terminals located in the cells modified as the main cells.</p> |
