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.

Abstract: An STA MLD can receive traffic indication map (TIM) information from an access point (AP) MLD in a wireless local area network (LAN) system. The TIM information can include a TIM bitmap and a link bitmap. The TIM bitmap includes a bitmap related to whether data to be transmitted by the AP MLD to each receiving MLD is present, and the receiving MLD can include the STA MLD. The link bitmap can include information related to a link of the receiving MLD, in which the data to be transmitted by the AP MLD is present, from among the receiving MLDs. The STA MLD can receive wake-up link information from the AP MLD. The wake-up link information can include information related to a link to be woken up from among links of the STA MLD.
