摘要

PURPOSE: A device and a method for power control for a cooperative transmission in a broadband wireless communication system are provided to determine the power ratio of terminals which performs cooperative transmission.;CONSTITUTION: A control unit(406) determines power ratio of transmission terminal verses cooperative terminal in at least one sub band in which a cooperative transmission is performed. The control unit generates power type which expresses the total transmission power of each terminal which participates in a cooperative transmission by the transmission power per sub band. The control unit transforms the power type into a simultaneous equation which expresses the water filling level of a channel gain. The control unit determines the transmission power per sub band of each terminal by solving the simultaneous equation.;COPYRIGHT KIPO 2012
