Abstract

A method at user equipment 'UE', the method comprising: determining one or more radio channel estimates from received signals; selecting a precoding index fulfilling an optimisation criterion based on the one or more radio channel estimates and a reduced precoding matrix, wherein the reduced precoding matrix comprises properties of a single beam for each of one or more polarisation planes, and the reduced precoding matrix corresponds to an expanded precoding matrix comprising properties of a plurality of beams for each of one or more polarisation planes; and transmitting a precoding matrix indicator 'PMI' based on the selected precoding index.
