    摘要： A method and apparatus for controlling transmission power in a wireless network area is provided. A target base station may control transmission power in cooperation with a neighboring base station and, thus, a satisfaction with a Quality of Service (QoS) of target terminals may be improved. Additionally, the target base station may determine whether to control the transmission power in cooperation with the neighboring base station, based on a possible improvement in satisfaction with the QoS of the target terminals.
