Apparatus and method for performing handover in multiple component carrier system

摘要

A method for performing handover in a multiple component carrier system includes a UE transmitting a measurement report message, including measurement values for one or more cells, to a source BS, the source BS transmitting a handover request message, including at least one of a candidate cell list including at least one candidate cell to be used in a target BS, an aggregatable cell list including at least one aggregatable cell in which UE capability is taken into consideration, and a list of sensible cells including at least one cell defined based on a similarity sensitivity of a measured frequency, to the target BS based on the measurement value, the source BS checking the cell included in the at least one list, receiving a handover ACK message including a final cell from the target BS, and determining handover, and the source BS transmitting a handover command message to the UE.

主权项

1. A method for performing handover by a source Base Station (BS) in a multiple component carrier system, the method comprising:
receiving, from a User Equipment (UE), a measurement report comprising measurement results for one or more cells; configuring a candidate cell list including one or more candidate cells arranged in an order according to the measurement results, the candidate cell list providing at least one information set, each information set including an identifier indicating one of the candidate cells and a corresponding carrier frequency; transmitting, to a target BS, a handover request message comprising the candidate cell list; receiving, from the target BS, a handover request acknowledge (ACK) message indicating admission of the handover; and transmitting, to the UE, a handover command message commanding the handover.
