Abstract: There is provided a method at a user equipment, comprising:
receiving transmission on two different polarizations over a wireless channel from net-work; determining a plurality of coefficients associated with a precoding matrix based on channel measurements of the reception, wherein the coefficients at least partially define a combination matrix; selecting a coefficient among the coefficients of the weaker polarization, the selected coefficient being a reference coefficient for the weaker polarization; determining a first indicator and a second indicator for the reference coefficient, wherein the first indicator indicates a position of the reference coefficient in the combination matrix and the second indicator comprises an amplitude value associated with the reference coefficient; reporting the first and second indicators to the network.
