1. A user equipment (UE) comprising:
a transceiver configured to receive configuration information about a channel state information (CSI) report, the configuration information including a number of radio remote heads (RRHs), NRRH>1; and
a processor operably coupled to the transceiver, the processor configured, based on the configuration information, to:
select a subset of RRHs from the NRRH RRHs independently for each subband (SB), and
determine the CSI report including an indicator indicating the selected subset of RRHs for each SB;
wherein the transceiver is further configured to transmit the CSI report including the indicator indicating the selected subset of RRHs for each SB.
