Abstract:
A Network Node, a UE operable in a MIMO system and respective methods performed by the Network Node and UE are provided for determining a precoder of a Codebook to use for transmissions to the UE. The Network Node includes at least two transmitting antennas corresponding to two individual Ranks. The Network Node determines which precoders the UE shall evaluate, and transmits, to the UE, the determined precoders the UE shall evaluate. The Network Node receives, from the UE, a PMI, associated with one of the determined precoders, which the UE requests the Network Node to use for transmission to the UE; and the Network Node transmits, to the UE, data using the requested precoders.
