Abstract
Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA through a first band, and decodes the PPDU. The PPDU comprises a control field and a data field. When the first band is an 80 MHz band comprising first to fourth 20 MHz subchannels, the first 20 MHz subchannel comprises first multiple RUs in which a first 26RU and a first 52RU are aggregated. The first 26RU is an RU located in the middle of the first 20 MHz subchannel. The first 52RU is an RU having a frequency lower than that of the first 26RU, and which is adjacent to the first 26RU.
