In accordance with an example embodiment of the present invention, a method, apparatus and software program product for partitioning channel state information into groups of different priority levels, wherein said channel state information comprises non zero coefficients and said partitioning comprises using at least one permutation function to prioritize said non-zero coefficients substantially based on an amplitude distribution of said non zero coefficients to determine mapping of said non zero coefficients to said groups, and further for omitting zero or more non-zero coefficients in accordance with said amplitude distribution based prioritizing from said groups, and for transmitting remaining non zero coefficients in said groups.
