Interference Mitigation For Full Duplex Communication

Disclosed is a method for suppression, at a first radio access node, of interference caused by one or more other radio access nodes when the first radio access node and/or the other radio access nodes operate in a full duplex mode. The full duplex mode comprises simultaneous transmission and reception in a same frequency interval.The method comprises acquiring measurements indicative of channel conditions between the one or more other radio access nodes and the first radio access node, wherein channel conditions indicate interference caused at the first radio access node by the one or more other radio access nodes.The method also comprises selecting a set of radio access nodes from the one or more other radio access nodes based on the channel conditions between the one or more other radio access nodes and the first radio access node, and determining an uplink receive filter for suppression of interference at the first radio access node based on the channel conditions between the selected set of radio access nodes and the first radio access node.In some embodiments, the method further comprises controlling one or more user devices served by the first radio access node to apply an uplink transmit beamforming which is based on the uplink receive filter.Corresponding user device method, apparatuses, network node, user device, and computer program product are also disclosed.
