Methods and apparatus as described herein for determining whether to transmit a signal to at least one receiver of a plurality of receivers with an orthogonal multiplexing technique while signals to a remainder of the plurality of receivers are simultaneously transmitted with a non-orthogonal multiplexing technique If it is determined that the signal should be transmitted to the at least one receiver with the orthogonal multiplexing technique, simultaneously transmitting the signal to the at least one receiver with the orthogonal multiplexing technique and the signals to the remainder of the plurality of receivers with the non-orthogonal multiplexing technique. Methods and apparatus are also described for decoding the signals on the receiving end.
