Relay node interface related layer 2 measurements and relay node handling in network load balancing

摘要

A method for performing radio usage measurements to support radio link operations and/or load balancing may be performed at an evolved Node B (eNB). The method may include determining a first radio usage parameter. The first radio usage parameter may be a measurement of radio usage between an eNB and at least one wireless transmit receive unit (WTRU). The method may further include determining a second radio usage parameter. The second radio usage parameter may be a measurement of radio usage between the eNB and at least one relay node (RN) served by the eNB. The method may further include utilizing at least one of the first radio usage parameter or the second radio usage parameter to evaluate at least one of evolved universal terrestrial radio access (E-UTRA) radio link operations, radio resource management (RRM), network operations and maintenance (OAM), and self-organizing networks (SON) functions or functionalities.

1. A method for handing over a relay node (RN) from a source evolved Node B (eNB) to a target eNB, the method comprising:
the source eNB determining to handover the RN to the target eNB; the source eNB sending a handover command to the RN, the handover command indicating that the RN is to handover from the source eNB to the target eNB; and the source eNB sending bearer context information to the target eNB, wherein the bearer context information comprises information that allows the target eNB to accept the RN while at least one wireless transmit/receive unit (WTRU) connected to the RN remains in the connected state throughout the handover.
