Abstract: The present document relates to a method for transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal for transmission data of a plurality of stations (STAs) by an access point (AP) in a wireless LAN (WLAN) system, and an apparatus therefor. To this end, the AP transmits a trigger frame to the plurality of STAs, and on receiving data from the plurality of STAs in response to the trigger frame, transmits ACK/NACK signals for the data received from the plurality of STAs through a multiuser block ACK frame (M-BA frame). Here, the M-BA frame includes ACK/NACK signals for STAs, the number of which is determined so as not to exceed a specific transmission unit time, among the ACK/NACK signals for the plurality of STAs, and the AP additionally transmits ACK/NACK signals to one or more STAs, to which ACK/NACK signals have not been transmitted through the M-BA, among the plurality of STAs.
