摘要：Adaptive power management methods and systems for a first station and asecond station in a wireless network. Each station operating in the power-saving (PS)mode adaptively determines a “listen interval” (LI) according to residual power state,

quality-of-service requirements, or other considerations. The LI is composed of a“normal beacon interval” (NBI) followed by the combination of “beacon-window-onlybeacon intervals” (BBIs) and “sleep beacon intervals” (SBIs). The LI value is one or aprime number which is larger than two, and the positions of the NBI and BBIs in an LIform a cyclic difference set. Each station broadcasts a beacon frame comprising at leastinformation about “the remaining number of BIs (RBI)” within a beacon window. Oncethe first station correctly receives the beacon frame from the second station, the firststation predicts the awake/sleep schedule of the second station, and transmits dataframes to the second station at the NBI of the second station.
