Abstract
The present invention ensures that the UEs are able to make use of all the available reference signals that can be used in a cell for performing UE measurements estimations or demodulations. That is achieved by indicating on a downlink common or shared channel the MIMO mode settings associated with a specific network node. The indicated MIMO mode settings explicitly or implicitly indicate available common reference signals and/or dedicated reference signals to be used for said UE measurements estimations or demodulations which implies that measurements estimations or demodulations can be performed based on said received indication.
