Abstract
A method for radio communication between a transmitting node and receiving nodes comprises obtaining (S) of directions from the transmitting node to the receiving nodes and antenna gains needed for each direction. A beam forming solution having a high gain in the directions of a set of receiving nodes and with antenna gains adapted to the need of the link is obtained (S). User data to be transmitted to the receiving nodes is obtained (S). The user data is overlay-coded (S) by a code-domain overlaid code and/or a frequency-domain overlaid code, separately for each respective receiving node. The overlaid-coded user data is combined (S) into at least one combined signal stream. Analogue beamforming, hybrid beamforming or constrained beamforming is performed (S) on the combined signal stream(s) according to the beam forming solution. The beamformed data is transmitted (S) from the transmitting node to the receiving nodes.
