Abstract

The invention relates to a method performed by a combination of a radio network node, a network node, and a user equipment (device) for reducing s feedback overhead. The method performed by the user equipment (device) decomposes each entry corresponding to a (i,j)-th combining coefficient of a precoder matrix into at least two coefficients then quantizing, each of the at least two coefficients and reporting information related to at least one phase value or at least one amplitude value of the quantized coefficients.
