Abstract
A user terminal () for a wireless communications system, equipped with at least two antennas () for the reception and/or transmission of traffic from a higher node (). The user terminal () is arranged to receive () said traffic in one or more data streams (S, S) i.e. with a rank of one or higher. The user terminal is arranged () to choose with which rank the higher node () should transmit the traffic to the user terminal () on, and to also signal this choice to the higher node (). The user terminal () is arranged to base its choice of rank on the estimated received data rate at the user terminal for different transmission ranks, the estimated power consumption in the user terminal for different transmission ranks and the Signal to Noise ratio, SIR, of the channel at the UE.
