1. A method, comprising:
receiving an IEEE 802.11 frame at a wireless local area network (WLAN) station;
determining whether the IEEE 802.11 frame is decodable by performing signal integrity checks of a physical layer convergence protocol (PLCP) header of the IEEE 802.11 frame;
determining whether the IEEE 802.11 frame is un-decodable due to frame error by checking the PLCP header of the IEEE 802.11 frame;
determining whether the IEEE 802.11 frame is addressed to the WLAN station when the IEEE 802.11 frame is determined to be decodable; and
entering a reduced power state when the IEEE 802.11 frame is not un-decodable or not addressed to the WLAN station.
