Patent ID: 7457973

Claim:
A system for saving power in a wireless network, said system comprising: an access point having a priority queue; a schedule information vector (SIV) frame comprising: one or more schedules of wake-up times, corresponding to one or more stations, respectively; an Association ID (AID) field to numerate the one or more association ID s of the one or more stations for identifying one or more of the stations; an N SIV field to denote the number of stations scheduled in the current frame by denoting the number of association ID S contained in the AID field; and an algorithm for calculating a transmission time duration of downlink data from the access point to each of the stations, wherein the access point originates and transmits to the one or more stations the SIV frame of the scheduled wake-up times having a transmission order based on the transmission time duration calculations stored within the priority queue of the access point, and wherein the one or more stations selectively awake from a sleep mode for data transmission therewith based on the schedule.
