IPC: H04L1/14
Filed: 1987-06-22
Abstract: PURPOSE:To shorten the communication time and to improve the reliability for transmission of information by sending continuously the transmission data and then sending the transmission to be re-transmission after the transmission is through with other transmission data. CONSTITUTION:In a step 101 both the transmission data 1 and an error detectable CRC code are transmitted to the reception side from the transmission side. At the reception side the errors are checked based on all received data. When an error is checked, the data 1 is corrected and sent back to the transmission side in a step 103 with addition of the received CRC code. This returned data 1 is checked at the transmission side together with the CRC code. When these data and code are decided normal, they are transmitted continuously in steps 102 and 104 together with transmission data 2 and 3. While the transmission data is re-transmission in a step 106 after no data to be transmitted exists any more when decided as abnormal.
