Abstract: Proposed are a method and device for transmitting and receiving a PPDU in a wireless LAN system by setting a primary channel for each distributed antenna port in a DAS. Specifically, a reception STA acquires control information from a transmission STA. The reception STA receives allocation information about a first or second primary 20 MHz channel at a plurality of antenna ports. The reception STA receives the PPDU from the transmission STA on the basis of the allocation information. The transmission STA operates in a system in which the plurality of antenna ports are distributed. The first primary 20 MHz channel is a primary 20 MHz channel that is present in a single BSS. The second primary 20 MHz channel is an additional primary 20 MHz channel for each of the plurality of antenna ports.
