An apparatus in a user equipment node (UE) is configured to perform a method for channel feedback. The method includes determining, based on a common reference signal received from a base station and one or more channel conditions, a plurality of values for a receiver table. The method also includes determining a plurality of values for a decision table based on corresponding values in the receiver table and a predetermined interference table. The method further includes selecting a value from the decision table. In addition, the method includes transmitting, to the base station, at least one of a rank indicator (RI) value and a precoding matrix indicator (PMI) value associated with the selected value in the decision table.
