FIELD: physics, communications.
SUBSTANCE: invention relates to communication systems. The apparatus, system and method can facilitate provision of a plurality of data streams in corresponding subchannels and modulation of the first of these data streams at least in part using a modulation constellation, different from that used to modulate the second of these data streams. The method can also involve transmitting the first and second data streams using the same radio resource to user terminals which use different subchannels for that radio resource.
EFFECT: high bandwidth when transmitting speech and data.
