Claim 1:
2. A wireless communication terminal that is an originator for transmitting data, the wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
transmit an All ACK capable indicator to a recipient using the transceiver, wherein the All ACK capable indicator indicates that the originator supports for processing an All ACK, wherein the All ACK indicates that the recipient signals that all the MPDUs included in an Aggregate-MAC Protocol Data Unit (A-MPDU) transmitted from the originator are received,
transmit the A-MPDU to the recipient using the transceiver,
receive a block ACK (BA) frame from the recipient using the transceiver, wherein the BA frame includes a traffic identifier (TID) field usable for indicating a TID of a MPDU to be acknowledged in the BA frame, and
when a value of the TID field of the BA frame is a predetermined first value and a value of an ACK type field of the BA frame is a predetermined second value, determine that the BA frame indicates that all MPDUs included in the A-MPDU are received and does not include a bitmap indicating whether each MPDU included in the A-MPDU is received,
wherein the predetermined first value is predetermined for indicating that all MPDUs in the A-MPDU are received, is a value that cannot be used as a value of TID of traffic of data transmission, and is limited to one of 8 to 14 and not 15 which indicates management MPDU (MMPDU).
