Abstract: 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.

Abstract: In a Wireless Local Area Network system, an STA MLD may include a first STA and a second STA, and an access point (AP) MLD may include a first AP and a second AP. The first STA and the first AP operate over a first link, the second STA and the second AP operate over a second link, and the second STA may be in a doze state. The first STA may receive, through the first link, a notice frame including information related to a critical update that has occurred in the second AP. The second STA may acquire, from the first STA, information related to the critical update. The notice frame may include a management frame.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: In a wireless local area network (LAN) system, a station (STA) can receive, from an access point (AP), a physical protocol data unit (PPDU) including basic service set (BSS) load information. The BSS load information can include information related to the number of STAs associated with a BSS of the AP and the number of enabled STAs from among the STAs associated with the BSS of the AP. The STAs can decode the PPDU. The STAs associated with the BSS of the AP can include enabled STAs and disabled STAs. The disabled STAs can include STAs operating in links to which no traffic identifier (TID) is mapped. Links in which the enabled STAs operate can include links to which at least one traffic identifier (TID) is mapped.

Abstract: In a wireless local area network (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.

Abstract: 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.

Abstract: 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.

Abstract: 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.
