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.

Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. In detail, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first and second subblocks. The data field includes first data for the first subblock and second data for the second subblock. The first data is generated on the basis of data in which constellation mapping is performed on encoded data bits. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation thereto.
