  • Publication number: 20140233483
    Abstract: Disclosed are a method and device for transmitting a frame. The method for transmitting a frame includes a step of generating A-MPDU (aggregate MAC protocol data unit) and a step of transmitting A-MPDU. The A-MPDU includes a first AMPDU subframe and a second A-MPDU subframe, wherein the first A-MPDU subframe includes a data block, and the second AMPDU subframe includes an FEC (Forward Error Correction) coding block which is additionally used in the decoding of the data block. Thus, the STA is capable of preventing unnecessary power consumption of STA by selectively determining whether FEC information is received according to whether an error occurred in the decoded data.
