Abstract: The present invention relates to a method by which a station (STA) which operates in power save mode in a wireless LAN system transmits and receives frames. The method includes the steps of: obtaining a channel access authority on the basis of at least one slot time, wherein each slot time is the unit time when a channel is maintained in an idle state for a channel access by the STA; transmitting a power save (PS) poll frame requesting the transmission of a buffered frame to an access point (AP); and receiving a response frame from the AP in response to the PS poll frame. The length of each slot time is set to be longer than the transmission time of the PS poll frame.

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.
