1. A user equipment (UE) comprising:
a transceiver configured to receive configuration information about a channel state information (CSI) report, the configuration information including information about a number M denoting a number of frequency domain basis vectors; and
a processor operably coupled to the transceiver, the processor, based on the configuration information, configured to:
identify a value of M,
determine, based on the value of M, a frequency granularity of the CSI report from wideband (WB) and subband (SB), wherein the frequency granularity of the CSI report=WB when M=1, and
determine the CSI report according to the frequency granularity;
wherein the transceiver is further configured to transmit the CSI report.
