A relay resynchronization amble sequence managing synchronizing in the channel the first node frames with the relay second node frames is periodicaiiy transmitted to the relay second node.

The donor base station (42) acquires the relay node identifier during a relay node attach procedure from the relay node (44) or another node in the core network (e.g., mobile management entity (26)).

The method includes an access node allocating a plurality of disparate uplink resources to the relay node in a single downlink transmission to the relay node.

The network access node can be different from a network access node that serves the first relay node.

The donor base station (42) may use the relay node identifier to retrieve configuration information for the relay node (44).

A method including transmitting a binary vector from a source node to a relay node and receiving a signal vector at the relay node.

The relay node (150) comprises a first relay path (630) and a second relay path (640).

A relay node communication network node is provided.

The invention also proposes a corresponding Relay Node (RN).

The method also includes transmitting, by the relay node, estimates of information from the source node to a destination node.

Embodiments contemplate enabling relay node uplink control information transmission on an interface between a relay node and a donor eNodeB (DeNB) in one or more subframes.

User equipment or UE devices (185, 187) attached to the relay node (183) can then communicate certain status symbols to the e-Node B via the relay node to increase efficient use of the system.

Also disclosed is a system for authenticating a relay node.

The NAS activate default EPS bearer request/accept messages may be communicated between the mobile relay node mobility management entity (MME) and the MRN via the target De NB.

The method includes attaching a first relay node (107d), having one or more descendant nodes (107f- h, 106x-z), to a new parent relay node (107b).
