The Block Ack Bitmap field is 128 octets in length and is used to indicate the receiving status of up to 64
MSDUs. Bit position n of the Block Ack bitmap, if set to 1, acknowledges receipt of an MPDU with an
MPDU sequence control value equal to (Block Ack Starting Sequence Control + n). Bit position n of the
Block Ack bitmap, if set to 0, indicates that an MPDU with MPDU sequence control value equal to (Block
Ack Starting Sequence Control + n) has not been received. For unused fragment numbers of an MSDU, the
corresponding bits in the bitmap are set to 0.
