18. A data retransmission device, comprising a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to:
transmit a first Aggregate Medium Access Control Protocol Data Unit (A-MPDU) to a receiver, wherein the first A-MPDU comprises multiple data blocks, each data block is composed of multiple A-MPDU subframes, and the first A-MPDU comprises data block identification information for identifying the multiple data blocks comprised in the first A-MPDU;
receive a reception status of the first A-MPDU from the receiver, wherein the reception status of the first A-MPDU is used for indicating one or more A-MPDU subframes not correctly received in the multiple data blocks of the first A-MPDU; and
retransmit, to the receiver based on the reception status of the first A-MPDU, the one or more A-MPDU subframes not correctly received by grouping the one or more A-MPDU subframes not correctly received into a first data block and transmitting the first data block to the receiver.
