Multiple delivery traffic indication map (DTIM) per device within single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

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.

主权项

1. A wireless communication device comprising:
a processor configured to:
receive a plurality of frames from another wireless communication device;identify a plurality of restricted access windows (RAWs) specified within the plurality of frames;process the plurality of RAWs to determine whether the plurality of RAWs specify that the wireless communication device is included within at least one group of a plurality of wireless communication device groups to communicate with the another wireless communication device; andsupport communications with the another wireless communication device during a subset of RAWs within the plurality of RAWs having a delivery traffic indication message (DTIM) periodicity when it is determined that the wireless communication device is included within the at least one group of the plurality of wireless communication device groups to communicate with the another wireless communication device.
