A method for operating a UE for CSI reporting in a wireless communication system is provided. The method comprises receiving, from a BS, configuration information for a CSI report, the CSI report comprising a first CSI part and a second CSI part, the second CSI part including a total of Knon-zero coefficients across υ layers, determining a priority value for each of the total of Knon-zero coefficients, partitioning the second CSI part into Group 0, Group 1, and Group 2 such that, based on the determined priority values of the total of Knon-zero coefficients, indicators to non-zero coefficients having higher priority values are included in Group 1 and indicators to non-zero coefficients having lower priority values are included in Group 2, and transmitting, to the BS over an uplink (UL) channel, UL control information (UCI) including Group 0 or (Group 0, Group 1) or (Group 0, Group 1, Group 2) of the second CSI part. 2. The method of claim 1 , wherein the first group includes at least one indicator for indicating spatial domain basis vectors and a strongest coefficient indicator.3. The method of claim 1 , wherein at least one amplitude coefficient indicator and at least one phase coefficient indicator are included in the second group or the third group claim 1 , according to a priority value P claim 1 , the priority value P being associated with each of the at least one amplitude coefficient indicator and each of the at least one phase coefficient indicator.4. The method of claim 3 , wherein the priority value P corresponds to following equation:{'br': None, 'i': P', 'l, i, m', 'L·v·F', 'm', 'i+l,, '()=2·()+υ·'} l=1, . . . , v,', 'v is a number of layers,', 'i=0, . . . , 2L−1,', 'L is a number of beams,', 'F(m) is a predetermined function of frequency domain basis vector index m,', 'm=0, . . . , M−1, and', 'M is a number of frequency domain basis vectors., 'where5. The method of claim 3 , wherein the third group includes the at least one amplitude coefficient ...
