Abstract

Management frame map directed operational parameters within multiple user, multiple access, and/or MIMO wireless communications. A management frame map may be generated within and transmitted from a first wireless communication device to a group of other wireless communication devices. Thereafter, certain subsequently transmitted packets may be analyzed and processed by the receiving wireless communication devices based on that earlier received management frame map. One or more operational parameters are determined for a subsequently transmitted packet based on the previously received management frame map. The operational parameters govern the manner in which at least a portion of the subsequently transmitted packet is processed.
