Title: METHOD AND DEVICE FOR TRANSMITTING WAKEUP PACKET IN WIRELESS LAN SYSTEM
Abstract:
A method and a device for transmitting a wakeup packet to multiple users in a wireless LAN system are suggested. Particularly, a transmission device configures a wakeup packet and transmits same to multiple users. The wakeup packet includes a sequence including first information and second information, by applying an OOK method. The first information is configured with an on-signal, and the second information is configured with an off-signal. The on-signal is transferred via a first symbol generated by applying a first sequence to 13 successive subcarriers in the 20MHz band and performing 64-point IFFT on the subcarriers. The wakeup packet is transmitted via subbands within the 20MHz band. The subbands are assigned in the same number as the multiple users. The subbands are configured with a sequence obtained by applying phase rotation to a predetermined M sequence.
