Abstract: Proposed are a method and apparatus for receiving a PPDU on the basis of control information related to a pilot tone in a wireless LAN system. Particularly, a reception STA receives a PPDU from a transmission STA. The reception STA acquires control information related to a tone plan and pilot tone by decoding the PPDU. The reception STA decodes a data field of the PPDU on the basis of the control information. If a bandwidth of the PPDU is 480 MHz, the tone plan is a 6×996 tone RU or 3×2020 tone RU. An index of a first pilot tone within the 6×996 tone RU or 3×2020 tone RU is ±{112, 246, 360, 494, 598, 732, 846, 980, 1136, 1270, 1384, 1518, 1622, 1756, 1870, 2004, 2160, 2294, 2408, 2542, 2646, 2780, 2894, 3028}.

Abstract: Disclosed are a method and device for transmission or reception based on the distributed allocation of multiple resource units in a wireless LAN system. A method performed in a wireless LAN system by a station (STA) according to one embodiment of the present invention comprises the steps of: receiving distributed resource allocation information, related to a plurality of resource units (RUs) allocated to the STA, from an access point (AP); and performing uplink transmission or downlink reception with the AP on the basis of the distributed resource allocation information, wherein the distributed resource allocation information may be based on the number of the plurality of RUs and the resource allocation information for each of the plurality of RUs.

Abstract: Proposed are a method and apparatus for receiving a PPDU by configuring multiple primary channels in a wireless LAN system. Particularly, a reception STA receives control information from a transmission STA. The reception STA receives a PPDU from the transmission STA on the basis of the control information. The control information includes a UHR operation element. The UHR operation element includes multiple primary channel elements. The multiple primary channel elements include first and second fields. The first field includes information regarding the number of first primary 20 MHz channels and second primary 20 MHz channels. The second filed includes information regarding a location of a second primary 20 MHz channel. The location of the second primary 20 MHz channel indicates a location cyclically shifted with respect to a first primary 20 MHz channel.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system on the basis of tone plan-related control information. Specifically, a reception STA receives a PPDU from a transmission STA. The reception STA acquires tone plan-related control information by decoding the PPDU. The reception STA decodes a data field of the PPDU on the basis of the control information. If the PPDU is transmitted on the basis of non-OFDMA without puncturing, the tone plan is 2020-tone RU when the bandwidth of the PPDU is 160 MHz, the tone plan is 2×2020 tone RU when the bandwidth of the PPDU is 320 MHz, the tone plan is 3×2020 tone RU when the bandwidth of the PPDU is 480 MHz, and the tone plan is 4×2020 tone RU when the bandwidth of the PPDU is 640 MHz.
