Method and device for transmitting frame

摘要

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.

1. A method for transmitting a frame, the method comprising:
generating an aggregate MAC protocol data unit (A-MPDU) including a first A-MPDU subframe and a second A-MPDU subframe; and transmitting the A-MPDU, wherein the first A-MPDU subframe includes a data block which is divided into a first sub data block and a second sub data block, wherein the second A-MPDU subframe includes a forward error correction (FEC) coding block additionally used to decode the data block, wherein each of the first A-MPDU subframe and the second A-MPDU subframe includes an FEC MPDU indication for distinguishing the first A-MPDU subframe and the second A-MPDU subframe by using a first bit, a second bit and a third bit, wherein the first bit is used to indicate the first A-MPDU subframe, wherein the second bit is used to indicate the second A-MPDU subframe including a FEC coding block for the first sub data block, and wherein the third bit is used to indicate the second A-MPDU subframe including a FEC coding block for the second sub data block.
