1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying a portion of second part of channel state information (CSI) (CSI part 2) to be transmitted based on a priority of each of a plurality of CSIs in the CSI part 2;
mapping first part of the CSI (CSI part 1) and the identified portion of the CSI part 2 to bits of uplink control information (UCI); and
transmitting, to a base station, the mapped UCI bits on a physical uplink shared channel (PUSCH),
wherein the CSI part 1 includes a rank indicator (RI) and a channel quality indicator (CQI), and
wherein the CSI part 2 includes precoding matrix index (PMI),
wherein a priority of each of one or more subband CSI in the CSI part 2 is determined based on a serving cell index of a CSI report, and
wherein a subband CSI corresponding to a CSI report with a larger serving cell index corresponds to a lower priority.
