Abstract: Disclosed are a method and apparatus for transmitting a wake-up packet in a wireless LAN system. Specifically, a transmission apparatus composes a wake-up packet and transmits same to a receiving apparatus. An OOK scheme and Manchester coding are applied to the wake-up packet. The wake-up packet comprises a sequence containing first information and second information. The first information and second information comprise on and off signals. The on signal applies a first sequence on K number of successive subcarriers in a 20 MHz band, and is transmitted by means of a first symbol generated by carrying out a 64-point IFFT. In the first sequence, one from among a subcarrier having a subcarrier index that is an even number and subcarrier having a subcarrier index that is an odd number is nulled.
