Abstract: The present invention relates to methods of transmitting and receiving a frame, which are performed by a station operating in a power save mode in a wireless LAN system. The method includes: transmitting a poll frame requesting the transmission of a buffered frame to an access point AP, wherein the poll frame includes a sustain time field that indicates a service section; and receiving at least one buffered frame from the AP within the sustain time in response to the poll frame. A method is provided for transmitting and receiving a frame executed by a station (STA) operating in a power sub mode in a wireless LAN system. The method includes transmitting a first poll frame requesting the transmission of a buffered frame to an access point AP, receiving an acknowledgement ACK frame in response to the first poll frame, and receiving at least one buffered frame from the AP.
