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: According to various embodiments, a multi-link device (MLD) may transmit, to an access point (AP), a request frame for activating a power saving mechanism (PSM). The multi-link device may receive a response frame for activating the PSM. The multi-link device may activate the PSM in at least one of a first link or the second link on the basis of the response frame.

Abstract: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a 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 comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.

Abstract: The specification proposes a method for requesting information on a restricted TWT when an STA has failed to receive the information. According to an embodiment of the present specification, when an STA fails to acquire information on a restricted TWT, the STA may transmit, to an AP, a signal for requesting the information on the restricted TWT after a certain time elapses from a TBTT. The signal may be transmitted independently or may be transmitted together with another signal transmitted by the STA.
