Abstract: Disclosed are a method and device for a TB PPDU transmission and reception operation in a wireless LAN system. A method by which a first STA transmits a PPDU in a wireless LAN system according to an embodiment disclosed herein may comprise the steps of: receiving a trigger frame from an access point (AP), wherein the trigger frame includes first information related to supporting the transmission of a first type of TB PPDU and a second type of TB PPDU, and second information related to the bandwidth for TB PPDU transmission; and transmitting the first type of TB PPDU to the AP within a first bandwidth in the overall bandwidth identified by a first type of the first STA through the second information.
