Title:
METHOD AND APPARATUS FOR TRANSMITTING WAKEUP PACKET IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/043952
Kind Code:
A1
Abstract:
A method and an apparatus for transmitting a wakeup packet in a wireless LAN system are proposed. Particularly, a transmission device configures a wakeup packet and transmits the wakeup packet to a receiving device. The wakeup packet includes a sequence configured with first information and second information by applying an OOK method. The first information and the second information are configured with an on-signal or an off-signal. The on-signal is transmitted through a first symbol, which is generated by applying a first sequence to K consecutive subcarriers in the 20 MHz band and performing 64-point IFFT. The off-signal is transmitted through a second symbol, which is generated by applying a second sequence to K consecutive subcarriers in the 20 MHz band and performing 64-point IFFT. The first information and the second information are transmitted through a third symbol in which the first symbol or the second symbol is repeated.
