Abstract
A method and apparatus for improving power performance of a wireless adapter which adopts a time slicing scheme by dividing a beacon interval into multiple slices, and assigning these slices to the stations through the beacon frame. The stations wakeup at the appointed slices to receive their buffered frames from an access point, and may enter into sleep state once the transactions conclude. A further embodiment including formatting data into a control frame for use in a wireless local area network, the frame including an indication, for each station associated with the wireless local area network, whether frames are buffered awaiting transmission to each respective station, a number of time intervals between control frames, and at which time interval the transmission of the buffered frames will begin for each station having buffered frames awaiting transmission.
