METHOD AND DEVICE FOR TRANSMITTING WAKE-UP PACKET IN WIRELESS LAN SYSTEM

WIPO Patent Application WO/2019/093811

A1

A method and a device for transmitting a wake-up packet by applying an OOK scheme to a wireless LAN system are presented. Specifically, a transmission device configures a wake-up packet having a first data rate, and transmits the wake-up packet to a reception device. The wake-up packet includes first information and second information. The first information is set in the order of a first ON signal, an OFF signal, a first ON signal, and an OFF signal. The second information is set in the order of an OFF signal, a first ON signal, an OFF signal, and a first ON signal. The first ON signal is generated by applying a first sequence to 13 continuous subcarriers in a 20 MHz band and performing 64-point IFFT. A part of the first ON signal is set as a partial ON signal, and the remaining part of the first ON signal is set as an OFF signal. The partial ON signal is set as a second ON signal included in a wake-up packet having a second data rate.
