METHOD AND APPARATUS FOR CONTROLLING TRANSMISSION POWER IN WLAN SYSTEM

摘要

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.

1. A method for controlling a transmit power in a wireless local area network, the method comprising:
establishing, by an access point (AP), a basic service set with a first station and a second station; and receiving, by the AP, a first Request To Send (RTS) from the first station, wherein the first RTS frame includes information about a maximum allowed transmit power used for communication between the AP and the first station.
