1. A wireless communication terminal communicating wirelessly, the wireless communication terminal comprising:
a transceiver; and
a processor, wherein the processor is configured to:
receive trigger information from a base wireless communication terminal using the transceiver, wherein the trigger information triggers a transmission of a trigger-based physical layer protocol data unit (PPDU) by the wireless communication terminal, wherein when the trigger information is included in a trigger frame, the trigger frame comprises a traffic identifier (TID} Aggregation Limit field in a User Info field corresponding to the wireless communication terminal, wherein the TID Aggregation Limit field indicates whether aggregating one or more MAC Protocol Data Unit (MPDUs) requesting an immediate response to generate an Aggregate-MAC Protocol Data Unit (A-MPDU) is allowed and indicates a maximum number of TIDs that is allowed to be aggregated in the A-MPDU when the wireless communication terminal generates the A-MPDU,
when a value of the TID Aggregation Limit field is a predetermined value, generate the A-MPDU not to include one or more MPDUs requesting an immediate response,
wherein the predetermined value is 0, when the value of the TID Aggregation Limit field is within a predetermined range, generate the A-MPDU according to the maximum number of TIDs, and
transmit the trigger-based PPDU including the A-MPDU to the base wireless communication terminal.
