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: In a wireless local area network (LAN) system, a transmitting station (STA) may transmit a peer-to-peer (P2P) transmission request frame to an access point (AP). The transmitting STA may receive a P2P transmission response frame from the AP. The transmitting STA may receive a trigger frame from the AP. The trigger frame may include information related to whether same is for an uplink, P2P transmission or both an uplink and P2P transmission. The transmitting STA may transmit data to a receiving STA. The transmitting STA and the receiving STA may be non-AP STAs. The transmitting STA may transmit a null data packet announcement (NDPA) frame and a null data packet (NDP) frame to the receiving STA. The transmitting STA may receive, from the receiving STA, a feedback frame including state information for the channel between the transmitting STA and the receiving STA.

Abstract: In a wireless local area network (WLAN) system, a multi-link single radio (MLSR) station (STA) is an STA that cannot perform transmission and reception simultaneously on different links, and the MLSR STA may comprise a first receiving unit and a second receiving unit. The MLSR STA may transmit preferred link information related to a second link to an access point (AP) multi-link device (MLD) on a first link. The MLSR STA may receive an initial control frame from the AP MLD through the first receiving unit on the second link. The MLSR STA may receive a data frame from the AP MLD through the first and second receiving units on the second link.
