Abstract
Mixed mode operations within multiple user, multiple access, and/or MIMO wireless communications. Certain communication systems can include wireless communication devices of various capabilities therein (e.g., IEEE Task Group ac (TGac VHT), IEEE 802.11 amendment TGn, IEEE 802.11 amendment TGa, and/or other capabilities, etc.). In one manner of classification, wireless communication devices having legacy and newer/updated capabilities may inter-operate with one another, operate within a common region, and/or communicate via a common access point (AP). Coordination of such wireless communication devices (e.g., legacy and newer/updated) provides for their respective operation on a same set of clusters in accordance with various operational modes including: (1) time dividing medium access between the wireless communication devices of various capabilities, (2) assigning primary cluster(s) for a first capability set and assigning non-primary cluster(s) for a second capability set, etc., and/or (3) any combination of operational modes (1) and (2).
