Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of changing a component performed by a target base station, the method comprising: receiving a measurement result obtained by measuring a radio channel quality with respect to component carriers; determining a handover procedure for changing of a primary component carrier based on the measurement result, and performing a relevant control procedure; transmitting, to a user equipment, information associated with a component carrier to be con…
