1. A method for performing a handover procedure, by a target evolved NodeB (eNB), in a wireless communication system including a mobile relay node, the method comprising:
- receiving, from the mobile relay node, a handover request message containing a list of a plurality of user equipment (UE) groups;
performing an admission control for at least one UE group on the list; and
transmitting, to the mobile relay node, a handover request acknowledge message containing the at least one UE group that is admitted for handover,wherein the at least one UE group includes a plurality of UEs,wherein the plurality of UEs are UEs that have transmitted measurement reports to the mobile relay node during a predetermined time period,wherein the mobile relay node does not move, andwherein the handover request message contains information on the plurality of UEs.

Abstract
A method and apparatus for performing a handover procedure in a wireless communication system including a mobile relay node is provided. A target evolved NodeB (eNB) receives a handover request message containing a list of a plurality of user equipments (UEs) on the mobile relay node or a group handover indication. The target eNB performs an admission control for the plurality of UEs; and transmits a handover request acknowledge message containing a list of admitted UEs for handover among the plurality of UEs.
