1. A user equipment (UE), comprising:
a transceiver configured to receive configuration information for a channel state information (CSI) report, the configuration information indicating Ng antenna groups and a codebook, wherein Ng>1 and each antenna group comprises a plurality of channel state information reference signal (CSI-RS) ports; and
a processor operably coupled to the transceiver, the processor configured to:
identify a number of the antenna groups,
identify the codebook, and
determine the CSI report based on the identified number of the antenna groups and the codebook,
wherein:
the transceiver is further configured to transmit the CSI report,
the CSI report includes an indication about a selection of a subset of antenna groups from the Ng antenna groups,
the subset comprises N antenna groups and the CSI report is determined for the subset N antenna groups, where 1≤N<Ng, and
wherein each antenna group of the Ng antenna groups is partitioned into two subgroups, and when one of the Ng antenna groups is selected, then
(i) both sub-groups of the antenna group are selected, or
(ii) one of the sub-groups of the antenna group is selected.
