A power controller apparatus for use in a mobile radio system wherein, when an error is detected in a transmitted signal, the transmit power is increased and when no error is detected, the transmit power is reduced by a smaller amount thus maintaining a constant bit error rate related to the ratio of the up and down step sizes. The power controller also contains a comparator for comparing the data which is transmitted with the data which has been transmitted to a station and retransmitted back.
