Abstract
According to an aspect, a radio access network node supports the transmission of multi-user superposition transmissions, where multi-user superposition transmission comprises transmitting, in each of a plurality of time-frequency resource elements, a modulation symbol intended for a first UE and a modulation symbol intended for a second UE, using the same antennas and the same antenna precoding. The radio access network node receives multiple CSI reports from the first UE for a first reporting instance. One or more of the received multiple CSI reports correspond to one or more respective multi-user superposition transmission states. The radio access network node also determines whether to use multi-user superposition transmission or an orthogonal multiple access transmission for scheduling the first UE in a first scheduling interval, based on the received multiple CSI reports.
