A method for communicating with a plurality of communication devices (UEs) using a phased array antenna system including an array of antenna elements, the method involving: receiving a plurality of port signal streams, wherein the plurality of port signal streams was obtained by precoding a plurality of data streams, each data stream of the plurality of data streams intended for a different corresponding UE; and within the phased array antenna system, processing the plurality of port signal streams to (1) undo the precoding that was performed on the plurality of data streams, and (2) generate via the array of antenna elements a plurality of transmit beams, wherein each transmit beam is directed towards a corresponding different UE among the plurality of UEs and carries a corresponding transmit signal that is derived exclusively from the data stream among the plurality of data streams that is intended for that UE.
