Abstract
A user equipment (UE) capable of communicating with a base station (BS) includes a transceiver configured to receive a signal comprising a CSI process configuration, wherein the CSI process configuration comprises a CSI-RS resource configuration to identify a CSI-RS resource and a CSI-RS on the CSI-RS resource, and transmit a precoding matrix indicator to the base station, and a controller configured to derive the precoding matrix indicator utilizing the CSI-RS on the CSI-RS resource. When the CSI-RS resource configuration indicates 4 CSI-RS ports: the precoding matrix indicator has a 3-bit size when a rank to derive the precoding matrix indicator is one; the precoding matrix indicator has a 3-bit size when the rank is two; the precoding matrix indicator has a 2-bit size when the rank is three; and the precoding matrix indicator has a 1-bit size when the rank is four.
