Signaling methods and apparatus for advanced MIMO communication systems
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 plurality of CSI-RS resources, each CSI-RS resource configured with the number of antenna ports, and a controller configured to derive a CSI-RS resource indicator (CRI) by utilizing the CSI-RS, wherein the transceiver is further configured to transmit the CRI to the base station, and wherein when the number of antenna ports in each configured CSI-RS resource is one (1), reporting instances for the CRI are subframes satisfying an equation specified in the disclosure. The corresponding base station and method are also disclosed.
