    • The present invention proposes methods and devices to further improve relay systems operating on the basis of carrier aggregation on the access as well as on the backhaul link. Under an aspect of such approach, there is proposed a relay node as a device, comprising a transceiver device, configured to communicate via a first interface with a terminal and via a second interface with a remote network device, wherein communication via the first and/or second interface is configured to operate based on aggregation of plural individual component carriers, and a control device, configured to perform, per component carrier: detection of a change concerning a component carrier on the first interface, sending, responsive thereto, of update information pertaining to at least the first interface towards the remote network device, reception of reconfiguration instructions, implied by the detected change, to be applied on the first interface, and initiation of reconfiguration of the first interface based on the received instructions. Similar approach is applied to a donor eNB as well as to corresponding methods and computer program products.

    • There are provided measures for mobile relay support in relay-enhanced access networks. Such measures may exemplarily comprise setting up a first packet data connection for traffic in a relay-enhanced access network, which relates to first-type user terminals using the same access technology as a base station, from a mobile relay towards a packet data network via a first packet gateway functionality collocated with the base station currently serving the mobile relay, and setting up a second packet data connection for traffic in the relay-enhanced access network, which relates to second-type user terminals using another access technologies as the base station and the mobile relay, from the mobile relay towards the packet data network via a second packet gateway functionality external to the base station currently serving the mobile relay. Such measures may exemplarily also comprise at least one of conveying additional context information for one or more contexts of user terminals connecting to the mobile relay from a source base station to the mobile relay, and initiating a group context update procedure for one or more contexts of user terminals connecting to the mobile relay in at least one of the mobile relay, the target base station, a mobility management entity of the user terminal, any selected mobility management entity in case the mobility management entity of the user terminal is unavailable, and a serving gateway entity of the user terminal.
