First Claim
1. A method of supporting handover at a first network entity in a mobile communication system, the method comprising:
- transmitting a plurality of data blocks of a first layer to a user equipment;
checking whether each of the plurality of data blocks is successfully transmitted to the user equipment; and
transmitting to a second network entity at least one data block of the first layer excluding a data block which is successfully transmitted to the user equipment among the plurality of data blocks of the first layer, the second network entity being a target network entity for handover of the user equipment.
