摘要

PURPOSE: A method and a device for controlling a receiving power consumption in a wireless LAN based on CSMA/CA(Carrier Sense Multiple Access/Collision Avoidance) are provided to turn off power of the rest components except a minimum number of components necessary for stabilizing, thereby reducing power consumed during a medium sensing operation. CONSTITUTION: An RPC(Receive Power Controller) receives a PLCP(Physical Layer Convergence Protocol) and an MAC frame(50), and extracts a transmission rate and frame transmission section information from the received information(51), then determines a power control section by interpreting the extracted information(52). The RPC compares a receiving address of the MAC frame with a self address(53). If the compared addresses are different, the RPC converts power of a baseband layer and an RF layer into a low-power state(54). When the power is off, the RPC counts the power control section(55), and converts the low-power state into a normal state(56). The RPC stabilizes an operation of the RF layer by applying the power(57).
