1. A user equipment (UE) comprising:

  • a transceiver configured to receive configuration information including a channel state information (CSI) process, a first multiple-input multiple-output (MIMO) Type, and a second MIMO Type; and

    a processor operably connected to the transceiver, the processor configured to calculate and report, in response to receipt of the configuration information, a CSI for each of the first and second MIMO Types; and

    wherein the second MIMO Type is Class B, corresponds to a beamformed CSI-RS, and is associated with a single CSI reference signal (CSI-RS) resource that includes at most 8 antenna ports,wherein the first MIMO Type is Class A, corresponds to a non-precoded CSI-RS, and is associated with a single CSI-RS resource that includes at least 8 antenna ports,wherein the CSI for the first MIMO Type includes a first precoding matrix indicator (PMI) i1 from a codebook including at least two PMIs (i1, i2) and a rank indicator (RI), andwherein the RI is either 1 or 3.
