    Abstract: A wireless communication system includes at least one transmit node having at least two transmit antenna ports, and at least one receive node having at least one receive antenna port. User information is transmitted between the at least two transmit antenna ports and the at least one receive antenna port on a radio propagation channel. A reconstructed channel state information (R-CSI) for a reconstructed radio propagation channel is computed. The reconstructed radio propagation channel is obtained as an estimated radio propagation channel compensated by a function of an estimated signal power imbalance between the at least two transmit antenna ports. And an indicative of the estimated signal power imbalance and the R-CSI is sent to the at least one transmit node.
