摘要： Proposed are a method and device for transmitting a feedback frame in a wireless LAN system. Specifically, a reception STA receives an NDPA frame from a transmission STA through a 320 MHz band. The reception STA receives an NDP frame from the transmission STA. The reception STA transmits a feedback frame to the transmission STA on the basis of the NDP frame. The NDPA frame includes information about a portion of the band. The information about the portion of the band includes a bitmap composed of the first to ninth bits.

摘要： Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a first STA broadcasts a sensing request frame. The first STA receives a first sensing response frame form a second STA and receives a second sensing response frame from a third STA. The sensing request frame includes STA identifier information and RU allocation information. The STA identifier information includes identifiers of the second and third STAs. The RU allocation information includes information about a first RU allocated to the second STA and information about a second RU allocated to the third STA. The first sensing response frame is received through the first RU. The second sensing response frame is received through the second RU.

摘要： In a wireless local area network system, a transmission STA may transmit a sensing start frame. The sensing start frame may include information related to the entire band in which WLAN sensing is performed, information related to a reception STA participating in the WLAN sensing, and information related to the number of bands K sensed by each reception STA and the bandwidth of the band sensed by the each reception STA. A transmission STA may transmit a sounding signal to the reception STA. A transmission STA may receive a feedback frame for the sounding signal from the reception STA. The feedback frame may include channel state information for K bands in the order of better channel state among the entire band.

摘要： In a wireless local area network (WLAN) system, a transmitting STA may transmit wake-up time information related to a receiving STA to the receiving STA. The transmitting STA may transmit a sensing start frame to the receiving STA during a wake-up time. The transmitting STA may transmit a sensing frame to the receiving STA. The transmitting STA may transmit a feedback requesting frame for the sensing frame to the receiving STA. The transmitting STA may receive a feedback frame for the sensing frame from the receiving STA. The wake-up time information may include duration information for maintaining an awake state in which the receiving STA can monitor a signal received from the transmitting STA, and period information for transitioning to the awake state.

摘要： An embodiment of the present invention relates to a technique for configuring a signal field in a wireless communication system. A receiving STA may receive and decode a PPDU. The PPDU may include a control information field, a plurality of signal fields, and a plurality of data fields. The control information field may be duplicated based on a first bandwidth, and the plurality of signal fields may be duplicated based on a second bandwidth. The second bandwidth may be set to be larger than the first bandwidth.

摘要： 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 20 MHz 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.
