Classification: CPC H | IPC H

Claim 14:
15. A method for operating a user equipment (UE), the method comprising:
receiving, from a base station (BS), CSI feedback configuration information;
determining, based on the CSI feedback configuration information, CSI feedback including, for each layer l of a total number of ν layers, a strongest coefficient indicator (SCI) for indicating an index of a strongest coefficient among KNZ,l coefficients, wherein l∈{1, . . . , ν} is a layer index, ν≥1 is a rank value, SCIl is the SCI for layer l, and KNZ,l is a number of non-zero coefficients for layer l;
determining a payload of the SCIl for each layer of the total number of ν layers based on the rank value;
for each layer l, remapping each index ml of the non-zero coefficients with respect to an index ml* associated with the strongest coefficient using a modulo function such that the index ml* is remapped to ml*=0, where ml*∈{0,1, . . . , M−1}; and
transmitting, to the BS, over an uplink (UL) channel, the CSI feedback including the SCIl for each layer of the total number of ν layers.
