Method and apparatus for transmitting wake-up packet in wireless lan system

A transmitting device for transmitting a wake-up packet in a wireless LAN system, comprising:

• a radio frequency (RF) unit transmitting or receiving radio signals;
• and
• a processor controlling the RF unit,
• wherein the processor:
• generates the wake-up packet, and
• transmits the wake-up packet to a receiving device,
• wherein an On-Off Keying (OOK) scheme and Manchester coding are applied to the wake-up packet,
• wherein the wake-up packet includes a first information and a second information,
• wherein the first information and the second information are configured of an ON-signal and an OFF-signal,
• wherein the ON-signal is transferred through a first symbol being generated by applying a first sequence to 13 consecutive subcarriers within a 20 MHz band and performing 64-point Inverse Fast Fourier Transform (IFFT), and
• wherein subcarriers having an odd-numbered subcarrier index among the 13 consecutive subcarriers are is nulled in the first sequence.
