More Information
Summary:Methods and apparatuses for CSI reporting mechanisms are provided. A user equipment (UE) apparatus includes a transceiver and a processor. The transceiver is configured to receive configuration information for a channel state information (CSI) reporting and receive configuration information for a plurality of precoding codebook parameters. The processor is operably connected to the transceiver, and configured to calculate, in response to receipt of the configuration information for the CSI reporting and the configuration information for the plurality of precoding codebook parameters, a first precoding matrix indicator (PMI) and a second PMI, wherein the first PMI includes one or two codebook indices. The transceiver is further configured to transmit the CSI reporting on an uplink channel, the CSI reporting including a channel quality indicator (CQI), a rank indicator (RI), and the calculated first and second PMIs.
