There are provided measures for a cell reconfiguration, more specifically a cell reconfiguration in a relay-enhanced network environment. Such measures exemplarily include recognizing a decision on a change of a configuration of a base station, informing a user equipment served by the base station due to a forthcoming change of at least one of a manipulated synchronization failure value or a manipulated radio link failure value before the configuration of the base station is changed, and providing the user equipment being served by the base station with a synchronization signal indicating a new configuration after the configuration of the base station is changed from an old configuration to the new configuration.

Synchronization of moving relay nodes and terminals in cellular networks

A User Equipment including at least one processor, and at least one memory for storing instructions to be executed by the processor, wherein the at least one memory and the instructions are configured to, with the at least one processor, cause the User Equipment at least: to conduct a processing for deciding whether or not it is acceptable to divert at least a part of a communication traffic of a communication currently conducted by the User Equipment with a first communication network to a second communication network, in case the decision is that it is not acceptable, to prepare a report indicating that the diversion of the communication traffic to the second communication network is not conducted, and to cause a transmission of the report to the first communication network.

Offloading traffic of a user equipment communication session from a cellular communication network to a wireless local area network (WLAN)

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.

Relay nodes

An apparatus is provided which includes a first connection unit configured to provide connection to a user equipment, and a processor configured to detect whether a handover of the user equipment is required, and, if a handover is required, to establish mobility information regarding the mobility state of the apparatus as mobility information of the user equipment, and to send the mobility information to at least one network element involved in the handover of the user equipment.

Signaling a new information element for the mobility state estimate of moving relay user equipments

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.

Various communication systems may benefit from load balancing. For example, wireless communication systems may benefit from controlled load balancing between access networks with various policies from different sources. A method can include selecting a rule to apply to a user equipment with respect to selection of radio access between cellular radio access and non-cellular radio access. The method can also include sending a traffic steering command to the user equipment, wherein the command contains an indication of the rule.

Controlled load balancing between access networks with various policies from different sources

At one node of a series of nodes supporting a series of wireless links to at least one communication device, transmitting information to assist the selection at at least one other node of said series of nodes of one or more carriers for the wireless link between said at least one other node and said communication device and/or a wireless link between said at least one other node and a further node of said series of nodes between said at least one other node and said communication device.

Carrier selection in relay systems

A method is provided wherein a base station and at least one further base station are assigned to a cooperation area, wherein a user equipment is served by the base station. The method comprises determining, by the base station, whether all user data of the user equipment being required for a precoding coordinated multipoint transmission is received by each of the base station and the at least one further base station, selecting a transmission mode, wherein the transmission mode is based, if all user data of the user equipment being required for a precoding coordinated multipoint transmission is received by each of the base station and the at least one further base station, on precoding coordinated multipoint transmission, or else, on an interference reducing transmission, and configuring, by the base station, the communication channel between the base station and the user equipment based on the selected transmission mode.

An apparatus and a method are described, by which interference related detection results of a plurality of relay nodes are obtained, wherein each relay node to the radio access network, wherein a connection between the relay node and its serving access node is an access node&#x2014;relay node connection. The relay nodes are grouped according to the obtained detection results such that the access node&#x2014;relay node connection can be configured for each group in order to mitigate interference to mitigate interference between transmissions to and from different relay nodes in each group.

A method of initiating configuration of at least one station includes receiving capability information of at least one second base station when the at least one station is within a cell area of a first base station. The method also includes determining some configuration information of the at least one station based on the received capability information. Configuring the at least one station according to the configuration information before the at least one station is handed over from the first base station to the at least one second base station is then initiated.

A value of a counter is incremented which corresponds to a potential cooperation area formed by the first cell corresponding to the first signal strength value and the n second cells corresponding to the n second signal strength values.
