Group resource allocation techniques for IEEE 802.16m are generally presented. In this regard a method is introduced comprising generating a plurality of bitmaps to identify resource allocations and multiple input multiple output (MIMO) modes for a group of broadband wireless mobile stations, wherein each mobile station in the group is assigned a position within a user bitmap to identify whether the mobile station is allocated frame resources and wherein the position within one or more MIMO bitmap(s) to identify a MIMO mode, and transmitting the bitmaps in a group resource allocation (GRA) information element (IE) of a broadband wireless media access protocol (MAP) frame portion. Other embodiments are also disclosed and claimed.
