Abstract
A method and apparatus for performing handover with a relay node (RN) are described. A donor eNodeB (eNB) includes circuitry configured to establish a wireless backhaul link with an RN and an X2 interface with at least one other eNB, circuitry configured to receive over the wireless backhaul link an X2 application protocol (X2AP) handover request message indicating that a wireless transmit/receive unit (WTRU) of the RN is being requested to be handed over to another eNB, and circuitry configured to send the handover request message to the another eNB over the X2 interface.
Claims10
A donor eNodeB (DeNB) comprising:
- circuitry configured to establish a wireless backhaul link with a relay node (RN) and an X2 interface with at least one other eNodeB;
- circuitry configured to receive over the wireless backhaul link an X2 application protocol (X2AP) handover request message indicating that a wireless transmit/receive unit (WTRU) of the RN is being requested to be handed over to another eNodeB;
- and
- circuitry configured to send the handover request message to the another eNodeB over the X2 interface.
A method for use by a donor eNodeB (DeNB), the method comprising:
- establishing, by a DeNB, a wireless backhaul link with a relay node (RN) and an X2 interface with at least one other eNodeB;
- receiving, by the DeNB, over the wireless backhaul link an X2 application protocol (X2AP) handover request message indicating that a wireless transmit/receive unit (WTRU) of the RN is being requested to be handed over to another eNodeB;
- and
- sending, by the DeNB, the handover request message to the another eNodeB over the X2 interface.
