`(57) Abstract: A communication method for transmitting a block acknowledgment (BlockAck) frame is presented. The communica-
`tion method includes receiving a plurality of frames from a transmitting device, wherein the payload of a frame may consist of either
`fragmented or unfragmented packet, recording the receive status of the frames, generating a BlockAck frame that contains at least
`one Bitmap field used to indicate the receive status of the frames, the number of bits allocated in the Bitmap field for a packet being
`variable and transmitting the BlockAck frame.
