1. A wireless communication terminal communicating wirelessly, the terminal comprising:a transceiver; and
wherein the processor is configured to;
receive trigger information from a base wireless communication terminal using the transceiver, wherein when the trigger information is a trigger frame, the trigger frame comprises a signaling field, wherein the signaling field indicates that the wireless communication terminal is not allowed to aggregate one or more MPDUs requesting an immediate response to generate an Aggregate-MAC Protocol Data Unit (A-MPDU) in response to the trigger information when a value of the signaling field is a predetermined value, and indicates a maximum number of traffic identifiers (TIDs) that is allowed to be aggregated in the A-MPDU when the value of the signaling field is within a predetermined range,
when the value of the signaling field is the predetermined value, generate the A-MPDU not to include the one or more MPDUs requesting an immediate response, when the value of the signaling field is within the predetermined range, generate the A-MPDU according to the maximum number of TIDs, and
transmit the A-MPDU to the base wireless communication terminal.
