METHODS OF TRANSMITTING AND RECEIVING FRAME BY STATION OPERATING IN POWER SAVE MODE IN WIRELESS LAN SYSTEM AND APPARATUS FOR SUPPORTING SAME

摘要

Provided is a method of transmitting and receiving a frame by a station (STA) in a power save mode in a wireless LAN system. The method includes: transmitting, to an access point (AP), a poll frame requesting transmission of a buffered frame, wherein the poll frame includes a duration field which indicates a service section; and receiving at least one buffered frame from the AP within the duration in response to the poll frame. Provided is another method of transmitting and receiving a frame executed by a station (STA) operating in a power save mode in a wireless LAN system. The method includes transmitting, to an access point (AP), a first poll frame requesting transmission of a buffered frame; receiving an acknowledgement frame (ACK frame) in response to the first poll frame; and receiving at least one buffered frame from the AP.
