Abstract:
The present invention relates to the signaling of channel quality information in a multi-beam transmission system, wherein a plurality of sets of channel quality information are transmitted for controlling the transmission rate on one of the beams, wherein each set of channel quality information is derived dependent on an assumed parameter of at least one other beam which could be transmitted, comprising selecting a parameter of the transmission of each of the sets of channel quality information dependent on the assumed parameter of the at least one other beam.
