Disclosed is an open-loop power control method for base station in a broadband GSM system. The method employs an open-loop control method and implements the power control for each carrier after synthesizing multi-way digital intermediate frequencies. In this method, the dynamic power level control and the slope power control are implemented individually by utilizing an inherent characteristic that the up-down slope control (including the static power control) of the respective carrier frequencies is performed synchronously. The open-loop power control method for multi-carrier according to the invention allows the power control for the respective carriers to be independent of each other completely, and the transmitting power of any carrier at any time slot can be varied flexibly and easily.

Disclosed is an open-loop power control method for base station in a broadband GSM system. The method employs an open-loop control method and implements the power control for each carrier before synthesizing multi-way digital intermediate frequencies. In this method, the dynamic power control and the slope power control are implemented individually firstly, then the multi-way synthesis is implemented, the static power control can be implemented according to the respective carrier frequencies, or it can be implemented in the common portion. The open-loop power control method for multi-carrier according to the invention allows the power control for the respective carriers to be independent of each other completely, and the transmitting power of any carrier at any time slot can be varied flexibly and easily.
