Abstract
A method performed by a first radio node for determining one or more precoders for beamforming of reference signals is provided. The reference signals relate to Channel State Information, CSI, of a forward link channel from the first radio node to a second radio node. The first radio node receives () reverse link reference signals from the second radio node and estimates () a first quality value of the forward link channel based on the received reverse link reference signal. The first radio node then determines () one or more first precoders of respective one or more first ranks based on the reverse link reference signal and the estimated first quality value. When the one or more first precoders have been determined, the first radio node triggers () a first transmission of one or more first forward link reference signals to the second radio node. The one or more first forward link reference signals are beamformed according to the determined respective one or more first precoders.
