Abstract

Systems and methods according to these exemplary embodiments provide for using demodulation reference signals (DM-RSs) to obtain channel state information (CSI) for precoder selection. A method includes: receiving a DM-RS in at least one subframe, determining the CSI from the DM-RS; and using the CSI to perform at least one function.
