obtaining duration information indicated by the trigger frame;
performing a data transmission in response to the reception of the trigger frame; and
receiving acknowledgement frame corresponding to the data transmission based on the duration information;
wherein, in response to the trigger frame, multiple data transmissions are simultaneously performed by a plurality of terminals in the same BSS when the plurality of terminals are indicated by the trigger frame, and
wherein the receiving the acknowledgement frame comprises, when a duration of the data transmission is shorter than a duration corresponding to the duration information indicated by the trigger frame, receiving the acknowledgement frame at a time determined based on the duration information indicated by the trigger frame.
