Abstract:
The invention relates to the Authorized Shared Access (ASA) concept in which a source node temporarily uses ASA spectrum as secondary user and on request of an ASA controller said ASA spectrum needs to be cleared (evacuated) and made available to a primary spectrum user and thus target nodes have to be selected by the source node to take over traffic from the source node; the source node thus obtains resource information of at least one target node for the spectrum clearance, choose at least one target node for clearance traffic transfers based on the resource information of the at least one target node, inform the chosen at least one target node about the coming traffic transfers, and transfer traffic by using a handover procedure; the target node reserves resources after receiving the information about the coming traffic transfers.
Abstract:
A method of reporting channel state information from a network element to a further network element of a communication network is provided, wherein the method includes decomposing the channel state information into different portions wherein the different portions correspond to channel state information varying on different time scales, and reporting at least one portion of the decomposed channel state information to a further network element.
Abstract:
There are provided measures for load balancing in relay-enhanced access networks with a relay device and multiple access devices, said measures exemplarily including the setting of multiple links between a backbone device of a backbone network and said multiple access devices, and a management of resource allocation of said multiple links between said backbone device and said multiple access devices in accordance with resource information of said multiple access devices indicating resource availability and resource assignment of said multiple access devices for establishing multiple connections between said backbone device and said relay device via said multiple access devices.
Abstract:
Measures are provided for mobile relay support in relay-enhanced access networks. Such measures include 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.

Abstract:
The invention relates to an access node in a communications network that is adapted for providing an identifier for a relay node including receiver means arranged to receive a message from the relay node, the message requesting an establishment of an interface over a communication link, checking means arranged to check data fields included in the message received, generating means arranged to generate the identifier, and transmitting means arranged to transmit the generated identifier to the relay node over the interface connection of communication link.
Abstract:
It is described an access module for a relay node for a radio telecommunication network. The access module includes an access communication part for providing a radio connection between the relay node and at least one user equipment, and an access interface for connecting the access module to a backhaul module of the relay node via an Internet Protocol network connection, wherein the access module and the backhaul module are spatially separated from each other. It is further described a backhaul module for a relay node, which includes a backhaul communication part for providing a radio connection between the relay node and a base station of the radio telecommunication network, and a backhaul interface for connecting the backhaul module to an access module of the relay node via an Internet Protocol network connection, wherein the backhaul module and the access module are spatially separated from each other. It is further described a relay node including such an access module and such a backhaul module and a radio message forwarding method, which is carried out with at least one of such a relay node.
Abstract:
There are provided measures for handover control for backhaul connections, said measures exemplarily including evaluation of the suitability of an access node cell in access network as target for a handover of a terminal based on delay information being indicative of an expected packet delay in a cell of the access node, wherein such delay information may be generated and/or exchanged in the access network. Said measures may exemplarily be applied for improving handover control in relay-enhanced access networks or networks that contain access nodes connected via different kinds of backhaul that can result in different end-to-end packet delays.
Abstract:
A method, including receiving, at a donor access node from a relay node associated with the donor access node, an identification of one or more other access nodes detected at the relay node and sending configuration information about said relay node from said donor access node to at least one of said one or more other access nodes in advance of an indication that a user equipment associated with the relay node has detected said at least one other access node, without at the same time sending said configuration information to at least one further access node that is detected by one or more other relay nodes or user equipments associated with the donor access node but not detected by said relay node. Wherein said configuration information includes information for setting up a communication with the relay node other than via a core network associated with the donor access node.
