CARRIER-AGGREGATION-BASED HANDOVER METHOD

摘要

Provided are a method for performing handover in a cellular mobile communication system that supports a carrier aggregation, and a user equipment and a node base (NodeB) using the method. A connection between the user equipment and the NodeB may be maintained and information may be exchanged using a plurality of serving carriers. Before performing the handover, the user equipment may perform measurement with respect to a neighboring NodeB supporting the carrier aggregation, and may provide parameter information to the NodeB in order to support a carrier aggregation function required for the handover. In a handover seamless environment, the continuity of a service may be provided and the performance of the service may be enhanced.

1. A handover method performed by a target base station, the handover method comprising:
receiving a radio channel quality information with respect to component carrier related to neighboring cell from a source station transmitting a setting information for carrier aggregation to the source station, wherein the component carrier receives the setting information for carrier aggregation, and performing a handover procedure with the target station using the setting information.
