There are provided measures for 3D beamforming in mobile network scenarios. Such measures exemplarily comprise configuring at least one CSI-RS resource (S21), transmitting at least one CSI-RS using said at least one CSI-RS resource (S22), receiving at least one matrix indicator indicative of a precoder selected from a precoder codebook and at least one channel quality indicator indicative of a radio channel state, each respectively associated with said at least one CSI-RS (S23), and determining a final precoder for 3D beamforming based on said at least one matrix indicator (S24). |
