METHOD FOR CONTROLLING A STATION AND STATION USING THE SAME
First Claim
1. A method of controlling a station connecting to an access point of a wireless local area network (WLAN), comprising:
- causing the station to enter a sleep mode;
providing an original wake-up time for the station operating in the sleep mode;
waking up at least one of the components of the station at the original wake-up time to receive a beacon frame from the access point;
parsing the beacon frame to extract traffic indication map (TIM) information specified therein; and
determining a next wake-up time by adjusting the original wake-up time according to the TIM information.

Abstract
A station connecting to an access point of a wireless local area network (WLAN) is disclosed. A radio frequency (RF) module demodulates received radio signals into baseband signals. A baseband module, coupled to the RF module, converts the baseband signals to a bit stream. A media access control (MAC) module, coupled to the baseband module, processes the bit stream to obtain data packets. An application specific integrated circuit (ASIC), coupled to the baseband module, and MAC module, causes the station to enter a sleep mode, wakes up at least one of the components of the station at a preset original wake-up time to receive a beacon frame from the access point, parses the beacon frame to extract traffic indication map (TIM) information specified therein, and determines a next wake-up time by adjusting the original wake-up time according to the TIM information.
