Abstract

There is presented mechanisms for providing information for determining beamforming weights or decoding user data for terminal devices. A method is performed by an RE of an access node. The RE has an interface to an REC of the access node. The method comprises obtaining information from the terminal devices to be used by the REC for determining the beamforming weights or decoding the user data. The method comprises selecting, according to a selection criterion, a part of the information to be provided to the REC in order for the REC to determine the beamforming weights or decode the user data based on the selected part of the information. The method comprises providing the selected part of the information to the REC over the interface.
