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: 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.

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.

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: Provided are a method and apparatus for requesting complete information or partial information on access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD includes a first transmitting station (STA) operating in the first link and a second transmitting STA operating in a second link. The receiving MLD includes a first receiving STA operating in the first link and a second receiving STA operating in the second link. The probe request frame includes a profile field of the second receiving STA.

Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a first band, and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first to fourth sub-blocks. The data field includes first data for first and second sub-blocks and second data for third and fourth sub-blocks. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation to the third sub-block.

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.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 0 −M 0 M 0 −M 0 M 0 −M 0 −M 0 M 0 M 0 −M 0 −M 0 M 0 −M 0 M 0 M 0 −M}*(1+j)/sqrt(2).
