1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive a trigger frame indicating simultaneous transmissions of one or more terminals in a basic service set (BSS) from an access point (AP),
wherein the trigger frame includes a length subfield for determining a length of an uplink frame transmitted in response to the trigger frame,
transmit the uplink frame in response to the trigger frame, and
receive an acknowledgement frame in response to the uplink frame,
wherein a first duration of the uplink frame is adjusted based on the length indicated by the length subfield of the trigger frame and a second duration of a data included in the uplink frame, and
wherein the acknowledgement frame is transmitted at a time determined according to the adjusted first duration for the transmission of the uplink frame.
