The present invention provides a transmit power controlling method for reducing
an influence of incorrect control in a mobile communication system in the CDMA mode.
A likelihood of transmit power controlling signal is generated on the basis of
the transmit power controlling signal transmitted by a radio base station and the
receiving quality, a variation amount of the transmit power is generated on the
basis of the likelihood, and the transmit power of a mobile station is controlled
on the basis of the variation amount.
