Abstract
Methods and apparatuses for CSI reporting mechanisms are provided. A user equipment (UE) includes a transceiver configured to receive channel state information (CSI) process configuration information with a plurality of non-zero-power (NZP) CSI reference signal (CSI-RS) resource configurations. The UE includes a processor operably connected to the transceiver, the processor configured to calculate, in response to receipt of the configuration information, a CSI report associated with a CSI-RS type or a multiple-input multiple-output (MIMO) type. The transceiver is further configured to transmit the CSI report on an uplink channel. At least one of the NZP CSI-RS resource configurations corresponds to a beamformed type.
