A method includes determining a total bandwidth for a downlink communication, segmenting the downlink communication into data units and assigning the data units to channels assigned to stations of a basic service set. The method also includes transmitting a channel announce frame to stations of the basic service set. The channel announce frame indicates each station assigned to receive a corresponding data unit, and one or more channels assigned to each station for transmitting the corresponding data unit. The method further includes transmitting the corresponding data units over the assigned channels to the assigned stations in a single downlink communication.
