1. A wireless communication terminal comprising:
a transceiver configured to transmit and receive wireless signals; and
a processor configured to process wireless signals transmitted or received through the transceiver,
wherein the processor is configured to:
receive, from an access point (AP), a trigger frame soliciting an uplink transmission from one or more terminals,
transmit a first physical layer protocol data unit (PPDU) in response to the trigger frame, and
receive an aggregate-medium access control (MAC) protocol data unit (A-MPDU) including an acknowledgement (Ack) frame in response to the first PPDU,
wherein the Ack frame is combined with a next trigger frame indicating transmission of a next PPDU and included in the A-MPDU when a process related to transmission of the next PPDU can be performed within a current transmission opportunity (TXOP),
wherein the trigger frame includes a duration field related to a TXOP duration, and
wherein the duration field is related to a specific value indicating a first time required for transmission of the first PPDU added to a second time required for the A-MPDU containing the Ack frame.
