Abstract: The present specification proposes a method of configuring and transmitting a PHY protocol data unit (PPDU) including first to fourth resource unit (RU) areas corresponding to at least first to fourth frequency bands. The first frequency band corresponds to a lowest frequency band, and the fourth frequency band corresponds to a highest frequency band. In the PPDU, a center RU area is arranged between the second RU area and the third RU area. In this case, the PPDU includes a second signal field corresponding to the second frequency band and a third signal field corresponding to the third frequency band. The second signal field may include a control field for the center RU area, and control information for a user allocated to the center RU area may be included a last field of a user-specific control field of the third signal field.

Abstract: Provides are a method and an apparatus for transmitting a feedback frame in a wireless local area network (WLAN) system. Specifically, a station (STA) receives, from an access point (AP), a null data packet announcement (NDPA) frame indicating transmission of a null data packet (NDP). The STA receives the NDP from the AP. The STA transmits, to the AP, a feedback frame including channel state information determined based on the NDP. The channel state information indicates a feedback subcarrier in each subcarrier group. The subcarrier group is generated based on grouping information using subcarriers in a frequency band excluding a guard subcarrier and a DC subcarrier. The feedback subcarrier is included in a subcarrier with an odd-numbered subcarrier index. The feedback subcarrier corresponds to a subcarrier with an even-numbered subcarrier index that is adjacent to the subcarrier with the odd-numbered subcarrier when the subcarrier with the odd-numbered subcarrier is a null subcarrier.
