ABSTRACT:
A base station apparatus for controlling power of individual control information transmitted to mobile stations. A first mobile station receives its own control information, and a second mobile station receives its own control information and control information for the first mobile station. A receiver receives information on forward channel conditions of the mobile stations for a previous time period. A channel transmitter transmits individual control information to the first mobile station and the second mobile station for a preset time period. A required transmission power calculator calculates power levels required for transmitting control information to each of the mobile stations for the preset time period taking into consideration the forward channel condition of each of the mobile stations and transmission power used for transmitting control information to each of the mobile stations for the previous time period. A transmission power controller transmits control information for the first mobile station at a higher power level out of the calculated required power levels and transmits control information for the second mobile station at a corresponding power level out of the calculated required power levels.
