Abstract

PURPOSE:To realize the partial retransmission in order to increase the transmission efficiency by sending both the retransmission text length and the flag in addition to the negative answer and then giving the partial retransmission indication of the text to the transmitter side in case the error character exists at the text receiving time. CONSTITUTION:The data is sent out from the center or terminal side, i.e., the transmitter side, and the error is checked at the terminal or center side of the receicer side. And the negative answer is sent to the transmitter side to secure the retransmission of the data at the transmitter side. In such control system, the receiver side transmits polling 1, NAK3 (negative answer), flag 4, length 5 and ACK7 each. While text 2, retransmission text 6 and EOT8 are transmitted from the transmitter side. Then flag 4 which is part of the negative answer is used for text 6 as the head or the end of text 2, along with length 5 used to indicate the length from the head or the end of text 2. And text 6 is decided by flag 4 and length 5 to be transmitted from the transmitter side.
