1. A method of retransmitting a coded data block to decode a failed MAC Protocol Data Unit (MPDU) of an Aggregated MPDU (A-MPDU) performed by a wireless device in a wireless network, the method comprising:
identifying a first codeword comprising a first bit of an A-MPDU subframe that carries the failed MPDU;
identifying a second codeword comprising a last bit of the failed MPDU;
encoding the coded data block using low-density parity-check (LDPC) or decoding an MPDU delimiter of the A-MPDU subframe, wherein the first and second codewords comprise LDPC codewords, and wherein the codewords between the first LDPC codeword and the second LDPC codeword comprise LDPC codewords; and
retransmitting the coded data block, the coded data block comprising the first codeword, the second codeword, and any codewords between the first codeword and the second codeword, wherein the first codeword in the coded data block is retransmitted without the MPDU delimiter, and
wherein the failed MPDU is operable to be decoded using the coded data block.
