Abstract: The present specification proposes technical features for improving various fields included in a PPDU. For example, a control signal field included in the PPDU may include a plurality of content channels and may be transmitted through a plurality of frequency segments. The plurality of content channels may include actual allocation information regarding a resource unit allocated to a specific frequency segment. Further, it may include preset information, not actual allocation information, regarding a resource unit allocated to another frequency segment. The preset information may be variously configured, for example, may be embodied as a zero user field.

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 an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 0 −M 0 M 0 −M 0 M 0 −M 0 −M 0 M 0 M 0 −M 0 −M 0 M 0 −M 0 M 0 M 0 −M}*(1+j)/sqrt(2).
