Abstract: 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.

Abstract: A methods, base station, wireless device and candidate relay device for supporting a D2D communication between a first wireless device and a second wireless device over a relay. The base station receives (302) from the first device an identity of a candidate relay wireless device and a first quality metric (Geq) pertaining to a first relay link between the first device and the candidate relay device and to a second relay link between the second device and the candidate relay device. The base station also obtains (304) a second quality metric (G12) pertaining to a D2D link between the first and second devices, and a third quality metric (G1 BS) pertaining to a cellular link between the base station and the first device. When the first quality metric (Geq) indicates a better link quality than both the second metric (G12) and the third metric (G1 BS), the base station selects (310) a relay mode for the D2D communication with the candidate relay device as the relay and instructs the involved devices accordingly.

Abstract: Embodiments herein relate to apparatuses and methods therein for enabling Radio Admission Control (RAC) of at least one Device-to-Device, D2D, service for a D2D communication between a first user equipment (UE) and a second UE in a radio communications network. The first UE is configured to transmit a D2D service request. Then, the first UE is configured to receive a RAC grant message or a RAC reject message in response to the transmitted D2D service request. Embodiments herein also relate to a Radio Access Node (RAN) a method therein, and to Core Network (CN) nodes and methods therein.
