1. the method (50) of a quantized channel state feedback, is characterized in that:

  • Determine the statistics (52) about each channel coefficients in multiple channel coefficients;

    Select separately speed (54) based on the statistics about each channel coefficients in multiple channel coefficients and be defined as the amount of bits that each channel coefficients in multiple channel coefficients distributes, the amount of bits of wherein distributing for each channel coefficients in multiple channel coefficients equals the speed selected based on the statistics about each channel coefficients in multiple channel coefficients;

    AndThe each channel coefficients (56) in described multiple channel coefficients is quantized separately with the respective rate selected based on the statistics about each channel coefficients in multiple channel coefficients.
