Abstract

A method and relay node for managing a plurality of relay nodes that is moving relative to a source network node, the method comprising: selecting a lead node; connecting the plurality of relay nodes to the lead node; and transmitting a signal to manage mobility of the plurality of relay nodes from the lead node to a network node.

Claims

1. A method for managing a plurality of relay nodes that is moving relative to a source network node, the method comprising:

selecting a lead node;

connecting the plurality of relay nodes to the lead node; and

transmitting a signal to manage mobility of the plurality of relay nodes from the lead node to a network node.

2. The method of claim 1, wherein the lead node is a relay node with user equipments (UEs) attached to it.

3. The method of claim 1, wherein the lead node is a dedicated relay node without user equipments (UEs) attached to it.

4. The method of claim 1, wherein the plurality of relay nodes are wirelessly connected to the lead node;

5. The method of claim 1, wherein the plurality of relay nodes are connected to the lead node via a wire;

6. The method of claim 1, wherein the network node is a source network node.

7. The method of claim 6, wherein the signal to manage mobility comprises a measurement report.

8. The method of claim 6, the signal to manage mobility comprises a request to initiate handover.

9. The method of claim 1, wherein the network node is a target network node.

10. The method of claim 9, wherein the signal to manage mobility comprises a random access signal.

11. The method of claim 9, wherein the signal to manage mobility comprises a RRC connection signal.

12. A first relay node, comprising:

a processor; and

a communications subsystem,

wherein the processor and communications subsystem cooperate to;

connect to one or more secondary relay nodes; and

transmit a signal from the first relay node to a network node to manage mobility of the one or more secondary relay nodes.

13. The first relay node of claim 12, wherein the first relay node has user equipments (UEs) attached to it.

14. The first relay node of claim 12, wherein the first relay node is a dedicated lead relay node without user equipments (UEs) attached to it.

15. The first relay node of claim 12, wherein the one or more secondary relay nodes are wirelessly connected to the first relay node;

16. The first relay node of claim 12, wherein the one or more secondary relay nodes are connected to the first relay node via a wire;

17. The first relay node of claim 12, wherein the network node is the source network node.

18. The first relay node of claim 17, wherein the signal to manage mobility comprises a measurement report.

19. The first relay node of claim 17, the signal to manage mobility comprises a request to initiate handover.

20. The first relay node of claim 12, wherein the network node is a target network node.

21. The first relay node of claim 20, wherein the signal to manage mobility comprises a random access signal.

22. The first relay node of claim 20, wherein the signal to manage mobility comprises a RRC connection signal.
