Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. In a case in which the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −j j j j 1 j j j 1 −1 −1 −1 j].

Abstract: According to various embodiments, a receiving station (STA) may receive a physical layer protocol data unit (PPDU). The PPDU may include a first signal field and a second signal field. The first signal field may include 3-bit information. The receiving STA may determine whether the PPDU is related to single user (SU) transmission or multiple user (MU) transmission, whether the PPDU is related to orthogonal frequency division multiple access (OFDMA), whether the PPDU is related to multi-user multiple input multiple output (MU-MIMO), and whether the PPDU is related to a trigger-based (TB) PPDU, based on the 3-bit information.
