Codeword automatic repeat request/decoding method and transmission/reception apparatus using feedback information

摘要

A codeword retransmission/decoding method and transmission/receiving apparatus uses feedback information. When a failure to decode data received from a receiving node occurs, the feedback information including success/failure information of the decoding and retransmission information are transmitted to a transmission node. The retransmission success probability may be increased when the retransmission feedback information is configured by the receiving apparatus repeating code-bits of the codeword just previously transmitted so as to demodulate the retransmission part.
