Abstract: A transmit power control method of a first station in a wireless LAN (WLAN) system includes: receiving path loss information from an (access point) AP, the path loss information containing a maximum value among path losses between the AP and at least one or more stations included in the WLAN system; controlling a transmit power by using the path loss information; and transmitting a frame according to the controlled transmit power. In said controlling the transmit power by using the path loss information, the transmit power is controlled by using a path loss obtained by adding the maximum value and a path loss between the first station and the AP or by using the path loss between the first station and the AP.
