Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. When a first band is a 40 MHz band, the first phase rotation value is [1, −1, −1, −1]. Each element of the first phase rotation value is applied for each 10 MHz band in the first band.

Abstract: The present specification provides a technical feature for extended range transmission in a wireless LAN signal. A physical protocol data unit (PPDU) of the present specification may include a universal signal (U-SIG) field. The U-SIG field may be received through first to the fourth symbols, the second symbol may include information in which bit information of the first symbol is repeated, and the fourth symbol may include information in which bit information of the third symbol is repeated. The receiving STA of the present specification may determine the transmission mode of the PPDU based on constellation mapping pattern of the first and second symbols.

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

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.
