| Zusammenfassung: | A method in a wireless device for determining a precoder is presented. The method comprises receiving reference signals from a network node, determining a channel estimate based on the received reference signals, and determining an optimal precoder based on the channel estimate, by determining at least one rotation factor and by selecting a subset of beams among a plurality of beams rotated by the at least one rotation factor. |
