1. A user equipment (UE) comprising:
a transceiver configured to:
receive a channel state information (CSI) report setting about a first type of quantities CSI(1), . . . , CSI(N) for N>1 groups of CSI reference signal (CSI-RS) ports; and
receive a CSI-RS resource setting about a second type of quantities CSI-RS(1), . . . , CSI-RS(K) transmitted from K groups of CSI-RS ports, where K>N; and
a processor operably coupled to the transceiver, the processor configured to, based on the CSI report setting and the CSI-RS resource setting:
measure CSI-RS(1), . . . , CSI-RS(K); and
determine, based on the measurement, CSI(1), . . . , CSI(N),
wherein the transceiver is further configured to transmit CSI(1), . . . , CSI(N),
wherein CSI(1), . . . , CSI(N) are N separate CSI reports, and
wherein for r=1, . . . , K, CSI-RS(r) is transmitted from one of the groups of CSI-RS ports associated with a CSI-RS resource.
