Abstract
The embodiments herein relate to a method performed by a UE () for providing a channel state information (CSI) feedback in a wireless communication system including at least the UE and a gNB () or a radio network node. The UE () is operative, by means of e.g. the processor () to: estimate the MIMO channel between the gl'JB () and the UE () based on received DL reference signals for the configured resource blocks. The UE () is further operative to calculate, based on a performance metric. a precoder matrix, for a number of antenna ports of the gNB () and configured subbands, the precoder matrix being based on two codebooks and a set of combination coefficients for complex scaling/combining one or more of vectors selected from a first codebook and a second codebook, and the UE () is operative to report a CSI feedback and/or a PMI and/or a PMI/RI, to the gNB (), used to indicate the precoder matrix for the configured antemia ports and resource blocks.
