1. A method in a wireless communication device for providing spatial channel information feedback, the method comprising:

  • receiving, at the wireless communication device, transmission from a plurality of antennas;

    receiving, at the wireless communication device, an indication of a feedback mode for feeding back spatial channel information, the spatial channel information based on correlations among at least some of the plurality of antennas;

    decomposing, at the wireless communication device, a correlation matrix representative of the correlations among at least some of the plurality of antennas into at least two Kronecker components,feeding back, from the wireless communication device, parameters representative of the Kronecker components according to the feedback mode indicated.
