    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 a legacy preamble and a first and a second signal field. The legacy preamble and the first and second signal fields are generated on the basis of a first and a second phase rotation value. When the broadband corresponds to a 320 MHz band, the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1]. An element of the first phase rotation value is applied to each 20 MHz band of the 320 MHz band. An element of the second phase rotation value is applied to each subcarrier of the 320 MHz band.

    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.

    Abstract: A method performed by a sharing access point (AP) of a wireless local area network (LAN) system may comprise the steps of: transmitting, to a shared AP, a first station (STA) list and a first measurement notification frame which requests measurement of received signal strength indicators (RSSIs) of signals transmitted from first STAs included in the first STA list; transmitting, to each of the first STAs, a request frame which requests information related to transmission power of the signals transmitted by the first STAs; receiving a report frame including the information related to the transmission power from each of the first STAs; transmitting a multi-AP transmission trigger frame to the shared AP; and transmitting data to each of the first STAs.

    Abstract: The method executed in a wireless local area network (WLAN) system, according to various embodiments, may comprise: a step in which a reception station (STA), which supports a multilink comprising a first link and a second link, receives a target wake time (TWT) element via the first link, wherein the TWT element is received via a beacon and includes information for TWT period configuration for the second link; a step in which the reception STA configures a TWT period for the second link on the basis of the TWT element; and a step in which the reception STA communicates with a transmission STA via the second link within the TWT period.

    Abstract: One embodiment according to the present specification relates to a method for performing low latency communication. A transmitting STA can transmit a low latency communication notification frame including information related to a section for low latency communication. The transmitting STA and a receiving STA can perform low latency communication in the section for low latency communication on the basis of the low latency communication notification frame. Afterward, the transmitting STA can transmit a low latency communication termination frame. The transmitting STA and the receiving STA can terminate the section for low latency communication on the basis of the low latency communication termination frame.
