Abstract
The embodiments herein relate to method performed by a radio network node (700), a network node (700), a method performed by a UE (500) and a UE (500) for reducing feedback overhead. The method perform by the UE (500) comprises at least: (401) decomposing each entry corresponding to a (i, j)-th combining coefficient of a precoder matrix into at least two coefficients; (402) quantizing, separately, each of said at least two coefficients with a least one bit, and (403) reporting information related to at least one phase value or at least one amplitude value or at least one phase value and an amplitude value of said quantized coefficient.
