Claim 16:
17. A radio frequency unit configured to provide signals for beamformed communication,
wherein the radio frequency unit is configured to retrieve, from a memory, first vector-associated data defined by an obtained first beam index;
said first beam index being assigned to a first signal;
said first signal being scheduled to be communicated by beamforming in a first direction;
said memory having stored therein vector-associated data characterizing at least two sets of beamforming vectors for each polarization and for each one of a plurality of beam directions;
said at least two sets of beamforming vectors for each polarization and for each one of a plurality of directions presenting different tapering and/or non-tapering;
whereby said first vector-associated data characterizing a first selected set of beamforming vectors, being designed to give a beam in said first direction;
wherein said first beam index comprises information for defining vector-associated data characterizing a particular one of said at least two sets of beamforming vectors for said first direction; and
wherein the radio frequency unit is further configured to initiate a beamforming for said first signal by use of said vector-associated data characterizing said first selected set of beamforming vectors;
characterized in that said beam index has a part beam index defining a partition of said data characterizing said sets of beamforming vectors of said memory, which partition being associated with vector-associated data of only one set of beamforming vectors for each polarization and for each one of a plurality of directions.
