ABSTRACT OF THE DISCLOSURE A request repeat method for data communication in which the receiving station transmits a signal indicating the result of reception of data transmitted thereto from the transmitting station. The receiving station transmits a signal indicating the unsatisfactory data reception repeatedly a maximum of N times until the receiving station is able to receive the data normally to request the transmitting station to transmit the data again, when the receiving station does not receive the data in a prescribed time after the receiving station has transmitted the signal indicating the unsatisfactory reception of the data to the transmitting station. Thus, the request repeat system eliminates useless communication charges necessary for restarting data communication after interruption and repetition of operation for requesting the repeated transmission of data, and hence the request repeat system is particularly effectively applicable to mobile data communication.
