Abstract: In the present invention, disclosed is a method for uplink multi-user transmission in a wireless communication system and an apparatus therefor. Specifically, a method for performing, by a station (STA), uplink (UL) multi-user (MU) transmission in a wireless communication system comprises the steps of: receiving, from an access point (AP), a trigger frame including information for UL MU transmission; and transmitting an UL MU PPDU on the basis of the information for UL MU transmission, wherein the trigger frame is a medium access control (MAC) frame, a MAC header of the trigger frame includes a type field and a subtype field, and the type of the trigger frame may be indicated by the type field and the subtype field.

Abstract: According to an embodiment of the present invention, a data transmission method for a station (STA) device in a wireless LAN (WLAN) system includes the steps of: generating a physical protocol data unit (PPDU) that includes a physical preamble and a data field; and transmitting the PPDU. Therein: the whole transmission band of the PPDU is made up of a plurality of resource units in a frequency region; each of the plurality of resource units is configured from a preset number of tones; resource units, from among the plurality of resource units, that have the same logical index are allocated to the same STA; and the resource units that have the same logical index may be discontinuously located in the frequency region.
