Disclosed are a method and device for transmitting a block acknowledgment frame, said method and device relating to the field of communications, and solving the problem of resource wastage caused by BA bitmap field redundancy. Specifically, the solution of the present invention is: a receiving device receiving at least one PPDU sent by at least one sending device, the PPDU including at least one MPDU; generating a BA frame according to reception conditions regarding the at least one MPDU within the at least one PPDU sent by each sending device within the at least one sending device, and sending the BA frame to the at least one sending device. The BA frame includes BA information corresponding to each sending device within the at least one sending device, and the BA information includes a block acknowledgment bitmap field and a bitmap length indicator. The bitmap length indicator is used for indicating the length of the block acknowledgment bitmap field, and the bitmap length indicator is carried in a block acknowledgment starting sequence control field included in the BA information of the BA frame, the BA information corresponding to the sending device. The present invention is used in a block acknowledgment frame transmission process. |
