Abstract: A relay node within a network, the network further comprising at least one donor node coupled to the relay node, and a mobile termination coupled to the relay node and at least one donor node, the relay node comprising means for: receiving a configuration message; configuring the relay node, based on the configuration message, to perform at least one of: receiving packets from the mobile termination and originating from one of the donor nodes; and sending packets to one of the donor nodes by transmitting them to the mobile termination.

Abstract: A method includes determining an estimate of a data packet path time from a first base station 13 to a user equipment (UE), and determining, based at least partially upon a communication received from a second base station 15, an estimate of a data packet path time from the first base station 13 via the second base station 15 to the user equipment (UE) 10. The method includes, based at least partially upon the determined estimates, selecting either the first base station 13 or the second base station 15 to transmit a packet data unit (DPU) (PDU) to the user equipment (UE) 10.

Abstract: A primary connection to a user terminal configured to operate using dual connectivity is maintained. A first control interface is maintained to a first radio node maintaining a secondary connection to the user terminal configured to operate using dual connectivity, the first radio node providing a local gateway for the user terminal. A second control interface is maintained to a core network and a local gateway towards a core network is emulated by providing control plane functions of the local gateway provided by the first radio node towards the core network over the second control interface. Local gateway related control messages are relayed between the core network and the first radio node over the first control interface.
