Claim 0:
1. A wireless communication terminal that is a recipient for receiving data, the wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive an All ACK capable indicator from an originator 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 wireless communication terminal signals that all the MPDUs included in an Aggregate-MAC Protocol Data Unit (A-MPDU) transmitted from the originator are received,
receive the A-MPDU from the originator using the transceiver, wherein the A-MPDU includes a plurality of MPDUs, each of which corresponds to a respective one of a plurality of a traffic identifier (TID)s,
when generating a block ACK (BA) frame, set a TID field of the BA frame, usable for indicating a TID of a MPDU to be acknowledged in the BA frame, to a predetermined first value and a value of an ACK type field of the BA frame to a predetermined second value, omit a bitmap indicating whether each MPDU included in the A-MPDU is received in the BA frame, and omit a Block ACK Starting Sequence Control field in the BA frame, 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), wherein the predetermined second value of the ACK type filed signals that the bitmap and Block ACK Starting Sequence Control field are omitted, and
transmit to the originator the BA frame using the transceiver.
