Abstract
This application discloses a retransmitted data sending method, a retransmitted data receiving method, and a related apparatus, and relates to the field of communications technologies. In this solution, a transmit end generates a retransmitted codeword based on information bits of each codeword corresponding to an incorrect MPDU, where the retransmitted codeword includes a codeword having some of information bits included in the incorrect MPDU. For the codeword having some of information bits included in the incorrect MPDU, the transmit end punctures a correctly received information bit in the codeword, and then sends the information bit. In this way, a receive end may directly perform combined decoding or joint decoding on an LLR of a codeword of a retransmitted MPDU and an LLR of a codeword of an MPDU that is incorrectly received last time. This improves transmission efficiency and transmission reliability.
