POWER-SAVING WITH DATA FETCH TIME, WITH END OF DATA INDICATION AND WITH MORE DATA ACKNOWLEDGEMENT Russian patent published in 2015 - IPC H04W52/02 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication. The disclosed method includes a step of receiving a power-saving polling frame from a station at an access point. The method also includes a step of, response to receiving the power-saving polling frame, transmitting a frame from the access point to the station indicating whether traffic associated with the station is buffered at the access point. The other disclosed method includes steps of: transmitting a frame from the station to the access point indicating that the station is to exit power-saving mode and refraining from entering power-saving mode until an end of data frame is received. Another disclosed method includes steps of: receiving a fetch trigger frame at the access point; and refraining from transmitting one or more fetched data frames from the access point until the fetch time elapses or until the fetch trigger frame is received. The access point is configured to communicate with other stations during fetch time.
