    摘要: Provided are a method and apparatus for generating a data frame. The method includes generating subframes from at least one media access control (MAC) service data unit (MSDU); generating a retransmission policy field for recording a policy related to a retransmission request, against an error occurring while the subframes are being transmitted, with regard to each of the subframes; and generating the data frame by using the subframes and the retransmission policy field which is generated with regard to each of the subframes.
