Abstract: A method and a device for transmitting a wake-up frame in a wireless LAN system are proposed. In particular, the transmission device configures a PPDU to which a first wireless LAN system is applied. The transmission device transmits, via the PPDU, a wake-up frame to which a second wireless LAN system is applied. The PPDU is transmitted via a first frequency band. The PPDU comprises a signal field and a data field. The signal field indicates that a data frame is transmitted in at least one RU excluding three 26-RUs located at the center of a second frequency band included in the first frequency band. The wake-up frame is transmitted via a 4 MHz band located at the center of the three 26-RUs. A coefficient is inserted in a first subcarrier constituting the 4 MHz band. The wake-up frame has an OOK scheme applied thereto and thus comprises an on signal and an off signal.

Abstract: Disclosed are a method and apparatus for transmitting a wake-up packet in a wireless LAN system. Specifically, a transmission apparatus composes a wake-up packet and transmits same to a receiving apparatus. An OOK scheme and Manchester coding are applied to the wake-up packet. The wake-up packet comprises a sequence containing first information and second information. The first information and second information comprise on and off signals. The on signal applies a first sequence on K number of successive subcarriers in a 20 MHz band, and is transmitted by means of a first symbol generated by carrying out a 64-point IFFT. In the first sequence, one from among a subcarrier having a subcarrier index that is an even number and subcarrier having a subcarrier index that is an odd number is nulled.

Abstract: Provided are a method and a device for transmitting a feedback frame in a wireless LAN system. Particularly, a first wireless station receives, from a second wireless station, a feedback request field including an LTF. The first wireless station configures feedback information on a wireless channel corresponding to a preset frequency band by using the feedback request field. The first wireless station transmits the feedback information to the second wireless station.

Abstract: Disclosed herein is a sounding method of a station (STA) for sending feedback information about a downlink (DL) channel state in a wireless LAN (WLAN) system. The sounding method includes receiving an NDP announcement (NDPA) frame providing notification of the transmission of a null data packet (NDP) frame; receiving the NDP frame; receiving a trigger frame comprising resource allocation information allocated to the STA; generating feedback information using the NDP frame; and sending a feedback frame comprising feedback information through uplink (UL) multi-user (MU) transmission using a frequency resource indicated by the resource allocation information. The feedback information may be generated in a frequency granularity (FG) unit with respect to a transmission bandwidth having a size smaller than or equal to the size of a transmission bandwidth of the NDP frame.
