1. A wireless communication terminal, the terminal comprising:
a processor; and
a communication unit,
wherein the processor is configured to:
transmit, through the communication unit, an aggregate MPDU (A-MPDU) consisting of one or more MAC protocol data units (MPDUs),
wherein the A-MPDU includes at least one MPDU delimiter information and one or more traffic ID(TID) related to the one or more MPDUs,
wherein each of the at least one MPDU delimiter information include an end of frame (EOF) field and a length field, and
receive, through the communication unit, a response frame of a specific format in response to the A-MPDU,
wherein the specific format of the response frame is determined as one of an Ack frame, a compressed BlockAck frame, and a multi-STA BlockAck frame based on a number of at least one TID for successfully received MPDUs among the one or more TIDs and a combination of the EOF field and the length field, and
wherein the at least one TID solicits an immediate response to the successfully received MPDUs.
