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.

Abstract: Provided is a method for receiving an uplink PPDU by using a plurality of RUs through a specific band in a wireless LAN system in which a plurality of bands is supported. Transmission of the uplink PPDU is disclosed by a trigger frame and the trigger frame indicates information on an identifier and a frequency resource of each station. In the trigger frame, an index field indicating the RU may be configured with the same size regardless of a bandwidth. To this end, a plurality of index groups is used instead of a method indicating a bitmap field or a start point/offset. A first index group of the index field may be used to indicate a first RU and a second index group of the index field may be used to indicate a second RU.

Abstract: A method and an apparatus for receiving a downlink frame in a wireless LAN are disclosed. The method and apparatus for receiving a downlink frame in a wireless LAN may comprises the steps of: an STA receiving from an AP a downlink frame via a downlink dedicated channel; and the STA transmitting to the AP a response frame related to the downlink frame via the downlink dedicated channel. The downlink dedicated channel allows transmission only of a contention-free downlink frame by the AP and a response frame by the STA, and restricts transmission of an independent uplink frame by the STA, wherein the independent uplink frame may be an uplink frame other than a response frame among uplink frames that are transmitted from the STA to the AP.
