Abstract: A method and an apparatus for transmitting a wakeup packet in a wireless LAN system are proposed. Specifically, a transmitter generates a wakeup packet by applying an OOK scheme. The transmitter transmits the wakeup packet to a receiver via an 80 MHz channel. The 80 MHz channel includes first to fourth subchannels. If some of the first to fourth subchannels are busy or there are no pending wakeup packets for the receiver in some of the subchannels, some of the subchannels are punctured. The wakeup packet is transmitted via the remaining subchannels of the first to fourth subchannels. Each of the first to fourth subchannels is a 20 MHz channel.

Abstract: Disclosed is a method for transmitting a preamble in a wireless LAN system, and a station device for performing the same. To this end, a station for transmitting a preamble configures a wireless frame including a first type terminal frame portion, and a second type terminal frame portion. The first type terminal frame portion includes a first type terminal preamble including a first type terminal short training field (STF) and a first type terminal long training field (LTF), and the second type terminal frame portion includes a second type terminal preamble including a second type terminal SFT and a second type terminal LTF. Here, the station configures the second type terminal preamble by allocating sequence components at an interval of an integer number of tones in a frequency domain and transmits the configured wireless frame to another station.
