Abstract

Communications are coordinated between different respective wireless communication device groups in a multiple delivery traffic indication map (DTIM) per device signaling scheme. Different respective wireless communication devices (e.g., wireless stations (STAs)) may communicate with a manager/coordinator wireless communication device (e.g., access point (AP)) at different times and for different reasons. The manager/coordinator wireless communication device generates and transmits beacons to the wireless communication devices specifying times during which communications may be supported with the manager/coordinator wireless communication device. A restricted access window (RAW) information element (IE) within a beacon includes at least one restricted access window (RAW) to specify a wireless communication device authorized to communicate with the manager/coordinator wireless communication device. Different wireless communication device groups may communicate with the manager/coordinator wireless communication device at different periodicities, and any one wireless communication device may be included in more than one wireless communication device group.
