Abstract: Proposed are a method and a device for requesting partial information from APs within a transmission MLD in a WLAN system. Particularly, a reception MLD transmits a probe request frame to a transmission MLD via a first link. The reception MLD receives a probe response frame from the transmission MLD via the first link. When the partial information regarding the first link and the partial information regarding the second link are the same, the partial information regarding the second link is requested on the basis of the first request element, and a value of a first full information profile sub-field is set to 0.

Abstract: In a wireless local area network (LAN) system, a transmission MLD may comprise a first station (STA) and a second station (STA), wherein the first STA operates in a first link, and the second STA operates in a second link. The transmission MLD may transmit a connection request frame to a reception MLD. The connection request frame may comprise capability information related to whether a restricted basic service set (BSS) mode is supported and information related to use of the restricted BSS mode. The information related to the use of the restricted BSS mode may comprise first information related to an STA which operates in the restricted BSS mode, among STAs included in the transmission MLD. The restricted BSS mode may mean a mode in which monitoring for signal reception is performed on the basis of acquisition of information, from an STA not operating in the restricted BSS mode, by the STA operating in the restricted BSS, the information indicating reception of a signal. The transmission MLD may receive a connection response frame from the reception MLD.

Abstract: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

Abstract: The present disclosure is related to a Long Training Field (LTF) signal used in a wireless local area network (WLAN) system. The LTF signal may be generated by a transmitting station (STA) and received by a receiving STA. The LTF signal may be included in a physical protocol data unit (PPDU), and the PPDU may be transmitted an 80 MHz band. The LTF sequence may include at least two parts, i.e., a first LTF sequence and a second LTF sequence.

Abstract: In a Wireless Local Area Network system, a reception STA can receive a request to send (RTS) frame. The RTS frame may include bandwidth information. The reception STA can perform clear channel assessment (CCA) on the basis of the bandwidth information. The reception STA can determine a transmission channel on the basis of the result of the CCA and information about preset multiple resource units (MRUs). The reception STA can transmit a clear to send (CTS) frame through the transmission channel. The transmission channel is one of the preset MRUs and may be a channel in which the CCA result is idle. The preset MRUs may include a first MRU composed of a first 996 tone RU, a second 996 tone RU, a third 996 tone RU, and a 484 tone RU.

Abstract: In a wireless local area network (WLAN) system, an access point (AP) multi-link device (MLD) may include a first AP and a second AP, the first AP may operate in a first link, and the second AP may operate in a second link. A station (STA) MLD may receive BSS information related to the first and second links, in which the AP MLD operates, from the AP MLD through the first link. The BSS information may include information related to the number of single radio STAs operating in the first link and the number of single radio STAs operating in the second link. The STA MLD may determine a link, in which the STA MLD is to operate, on the basis of the BSS information.
