Abstract
A base station, method, and computer-readable storage medium for channel state information (CSI) acquisition. The base station includes a transceiver configured to transmit a first, unprecoded channel state information reference signal (CSI-RS) on a first antenna dimension; receive a first CSI report on the first antenna dimension; transmit a second, precoded CSI-RS on a second antenna dimension; and receive a second CSI report on the second antenna dimension. The first CSI report includes a precoding matrix index (PMI), a rank indicator (RI), and channel quality indicator (CQI) for the first antenna dimension; and the second CSI report comprises a PMI, a RI, and a CQI for the second antenna dimension. The base station also includes a processor operably connected to the transceiver, the processor configured to generate a downlink (DL) CSI for multi-user multi-input, multi-output (MU-MIMO) scheduling and precoding based on the first CSI report and the second CSI report.
