A data error control method for data passing through error correction encoding. It has a radio frame including fields for storing the data, a data number associated with said data and a retransmission request data number. It receives the radio frame from a data transmitting end. If an error is detected as a result of decoding the data received, it stores the data number associated with said data into the field of the radio frame as the retransmission request data number, and transmits the radio frame to the data transmitting end. It receives the retransmission data associated with the data number from the data transmitting end. It can speed up the retransmission control and reduce the processing load of the network.
