1. A user equipment (“UE”) apparatus comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE apparatus to:
receive a reference signal;
identify a set of taps over a layer based on the reference signal, wherein the set of taps correspond to a set of sub-band indices;
generate a combinatorial codeword representing the set of taps; and
transmit a channel state information (“CSI”) report indicating the combinatorial codeword.
