Closed-loop signaling method for controlling multiple transmit beams and correspondingly adapted transceiver device
Abstract:
The present invention relates to a closed-loop signaling method for controlling multiple transmit beams, comprising the steps of receiving (S21) a plurality of at least two beams from a first transceiver (Node_B) via a plurality of transmission channels at a second transceiver (UE), evaluating (S22), at said second transceiver, characteristics of said plurality of beams received at said second transceiver, determining at least one dominant beam using said characteristic, deriving (S24) control information for being fed back from said second transceiver (UE) to said first transceiver (Node_B), based on said evaluated characteristics, wherein said control information for dominant characteristics is allocated a different quantization resolution as compared to a less dominant beam (S25, S26, S27). Also, the present invention relates to a transceiver device (UE), adapted for being used in such a closed-loop signaling method for controlling multiple transmit beams.
