Method for receiving data in wireless lan system, and terminal using same

A method for receiving data in a wireless LAN system according to an embodiment of the present specification comprises: a step in which an access point sets TXOP duration information for a plurality of uplink data units to be received from a plurality of stations via wireless resources which are individually set in an overlapped time period, wherein the TXOP duration information indicates a transmission opportunity period including a time period; a step in which the access point obtains TXOP limit information which indicates an allocable limit period for the plurality of stations; a step in which the access point determines whether the transmission opportunity period is included in the limit period on the basis of the TXOP duration information and the TXOP limit information; a step in which the access point transmits, to the plurality of stations, a trigger frame which requests transmission of the plurality of uplink data units on the basis of whether the transmission opportunity period is included in the limit period; and a step in which the access point receives the plurality of uplink data units from the plurality of stations in the transmission opportunity period.
