Abstract
Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects a BS may generate a port precoding matrix which compress a larger number of antenna elements to a smaller number of antenna ports transmit UE-specific port reference signals to a user equipment (UE) using the port precoding matrix receive feedback regarding channel state information (CSI) measured by the UE based on the UE- specific port reference signals map multiple data layers to UE-specific antenna ports based on the CSI map each of the UE-specific antenna ports to physical antenna elements and transmit data to the UE based on the mapping of the multiple data layers and the mapping of antenna ports to physical antenna elements.
