Changes in instructions for increasing/decreasing transmission power that have been decoded from TPC bits are monitored, and when the increase/decrease instructions in a prescribed time interval are biased toward instructions for increasing the transmission power, the peak direction or main lobe width of the transmission beam is changed by regulating the transmission power or transmission antenna weights that correspond to each of a plurality of antenna devices. These processes are repeated until the bias toward instructions for increasing the transmission power in the instructions for increasing/decreasing transmission power is eliminated or until the number of changes of the transmission beam reaches a maximum value that has been set in advance. <IMAGE> |
