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.
