Method and apparatus for controlling power consumption of stations on CSMA/CA-based wireless LAN

摘要

A method and apparatus are provided for controlling the power consumption of stations when the stations transmit and receive a wireless signal to and from one another on a CSMA/CA wireless LAN. The method involves extracting information on frame transmission speed and transmission period information on first and second layers from the wireless signal; determining a power-controlled period for each of the first and second layers based on the extracted information; and reducing the power consumption of the first and second layers by switching a current mode of the first and second layers to a pred
