SYSTEM AND METHOD FOR ADAPTIVE POLLING IN A WLAN

摘要

A method for scheduling data transmissions between a base station (110) and user terminals (130) in a wireless network. The method includes transmitting a first poll (260) from the base station (110) to a first user terminal traffic stream (S210). In response to the first poll to the base station, where a queue state of the first user terminal is indicated in the header of the first frame (210). The base station removes the first user terminal traffic stream from an active list when the first frame indicates that the queue state is empty (S230). The base station then calculates a deferral window (220) and schedules transmissions of other data frames between the base station and the user terminals that remain on the active list (S240 and S250). At the expiration of the deferral window, the first user terminal is returned to the active list (S260).
