Abstract: Disclosed are a method and an apparatus for transmitting an uplink frame in a wireless LAN. The method for transmitting an uplink frame in a wireless LAN may comprise: a step in which an STA receives a downlink PPDU from an AP through a downlink dedicated channel; a step in which the STA performs a first channel switching from the downlink dedicated channel to a general channel on the basis of information about TXOP duration for transmitting the downlink PPDU if STA indication information included in the received downlink PPDU does not indicate the STA and a pending uplink frame is present in the STA; a step in which the STA performs a channel access for transmitting the uplink frame via the general channel on a time resource corresponding to the TXOP duration; and a step in which the STA performs a second channel switching from the general channel to the downlink dedicated channel on the basis of the information about TXOP duration.
