Abstract: A method and a device for transmitting a wakeup packet in a wireless LAN system are suggested. Particularly, a transmission device configures a wakeup packet and transmits same to a reception device. The wakeup packet includes a sequence including first information and second information, by applying an OOK method. The first information and the second formation are configured with an on-signal and an off-signal. The on-signal is transferred via a first symbol generated by applying a first sequence to K number of successive subcarriers in the 20 MHz band and performing 64-point IFFT on the subcarriers. The offsignal is transferred via a second symbol generated by applying a second sequence to the K number of successive subcarriers in the 20 MHz band and performing 64-point IFNT on the subcarriers. Of the K number of subcarriers to which the first sequence is applied, a coefficient for m number of subcarriers as a unit is set to 1 or −1 for the subcarriers, and a coefficient for the remaining subcarriers is set to 0. The first information and the second information are transmitted via a third symbol configured with the first symbol and the second symbol, respectively.

Abstract: Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.
