Abstract

A first communication device is configured to communicate with a second communication device, the first communication device comprising circuitry configured to receive data units, a received data unit comprising an information part and at least a portion of a parity part of a codeword comprising said information part and said parity part, from the second communication device; provide an indication to the second communication device indicating at least one erroneous data unit that failed to be received or decoded by the first communication device: receive a retransmission of the erroneous data unit having an identical information part as the corresponding originally transmitted data unit: accumulate log-likelihood ratios (LLRs) of the erroneous data unit and the corresponding retransmission of the erroneous data unit; and decode the data unit based on the accumulated LLRs.
