DEVICE AND METHOD FOR CONTROLLING UPLINK POWER IN A MOBILE COMMUNICATION SYSTEM CAPABLE OF ACHIEVING THE UPLINK QUALITY IMPROVEMENT OF A TERMINAL AND RESTRICTION OF CELL INTERFERENCE BY CONSIDERING THE CHARACTERISTICS OF A MIMO TRANSMISSION

摘要

PURPOSE: A device and a method for controlling uplink power in a mobile communication system are provided to supply a new power control method about a terminal which used a multi transmission antenna.;CONSTITUTION: A plurality of transmission antenna transmits data through an uplink. A power controller per layer(211) receives the power control parameter through uplink. The power controller per layer sets the transmission power to the power control parameter corresponding to each transmission antennas by calculating the transmission power. Each plurality of power amplifiers(205,215,225,235) controls the data according to the transmission power by corresponding to the transmission antennas. The plurality of power amplifiers transmits the data through the uplink.;COPYRIGHT KIPO 2012
