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:
transmit an uplink PPDU(Physical layer Protocol Data Unit) to an AP(Access Point), and
receive an A-MPDU(aggregate medium access control(MAC) protocol data unit(MPDU) in response to the uplink PPDU, wherein the A-MPDU includes a trigger frame soliciting transmission of a next uplink PPDU and an acknowledgment frame for one or more PPDUs, including the uplink PPDU, transmitted from one or more terminals triggered by the AP, and wherein the trigger frame is included in the A-MPDU by being aggregated with the acknowledgement frame upon a process for the transmission of a next uplink PPDU being performed within a current TXOP(Transmission Opportunity).
