Abstract
Methods and apparatuses for CSI reporting mechanisms are provided. A user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is 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. The processor is configured to calculate and report, in response to receipt of the configuration information, a CSI for each of the first and second MIMO Types. The second MIMO Type is Class B and is associated with a single non-zero-power CSI reference signal (NZP CSI-RS) resource that includes at most 8 antenna ports.
