Patent ID: 10868704

Abstract:
Proposed are a method and a device for transmitting a wakeup packet in a wireless LAN system. Specifically, a transmission device configures a wakeup packet and transmits the wakeup packet to a reception device. The wakeup packet, to which an OOK scheme is applied, includes a sequence comprising first information and second information. The first information comprises an on-signal, and the second information comprises an off-signal. The on-signal is transferred through a first symbol generated by applying a first sequence to K continuous subcarriers in a 20 MHz band and performing 64-point IFFT thereon. In the K subcarriers to which the first sequence is applied, coefficients of subcarriers are set to 1 or −1 by a unit of m subcarriers, and coefficients of the remaining subcarriers are set to 0.
