Abstract: Disclosed is a pilot sequence transmission method for transmitting additional information to a receiver by shifting a pilot signal on a frequency axis or a time axis and transmitting the shifted pilot sequence. In addition, disclosed is a pilot sequence identification method for acquiring additional information transmitted from the transmitter by analyzing the pilot sequence transmitted from a transmitter so as to calculate a shifting value.

Abstract: Proposed are a method and 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 broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes a first field and a second field. The first field includes an L-LTF. The first field is generated on the basis of a first or second phase rotation value. The first phase rotation value is generated on the basis of a third phase rotation value and a fourth phase rotation value. The third phase rotation value is a phase rotation value obtained by repeating a phase rotation value for an 80 MHz band defined in an 802.11be wireless LAN system.
