Abstract
A method for addressing groups of stations in a wireless communication system begins by assigning the stations in the system into a number of groups. A group identifier is signaled to each station and the group identifier is indicated in a frame for each group that has data in the frame. The addressing method can be applied to power savings for the station, wherein the station enters a power saving mode if the group identifier for the station is not present in the frame.
