A method and apparatus provide antenna array channel feedback. The method can include receiving a first set of channel state information reference signals on resource elements, and a second set of channel state information reference signals on resource elements. The method can include determining a first precoding matrix based on the received first set of channel state information reference signals. The first precoding matrix can be chosen from a first codebook. The method can include determining a second precoding matrix based on the second set of channel state information reference signals. The second precoding matrix can be chosen from a second codebook that is different than the first codebook. The method can include transmitting a representation of at least one of the first precoding matrix and the second precoding matrix.
