Patent attributes
A method performed by a wireless device having a plurality of MAC addresses may comprise receiving a first group based transmission, on an operating band of a first AP, wherein the first group based transmission has a preamble portion which indicates a modulation scheme used for a portion subsequent to the preamble portion. The first group based transmission may have a first data portion and a first header portion. A second group based transmission may be received on an operating band of a second AP. The second group based transmission may have a second data portion. The second data portion may be modulated according to QAM and may include a second header portion. The wireless device may determine whether the first group based transmission comprises data which is duplicative of the second group based transmission.
