Abstract
The present invention relates to a method and arrangement in a transmitter unit of a multi-antenna system for an improved calculating of the antenna weights for a beamforming transmission of data from a transmitter unit to a target receiver unit, whereby interfering signal components for receiving units other than the target receiving unit and the desired communication signal at a target receiving unit are weighted by receiver-specific parameters describing the receiver capabilities of said units in terms of their capability for interference suppression and/or signal enhancement. The invention also relates to a method and arrangement for scheduling of user equipments by using said information on the signal processing capabilities for received signals of each receiving unit.
