Title:
HANDOVER WITH CARRIER AGGREGATION
Document Type and Number:
WIPO Patent Application WO/2011/142544
Kind Code:
A2
Abstract:
A handover with carrier aggregation is provided. A method of assisting handover of a user equipment from a source wireless access node to a target wireless access node, for use in a wireless access network having a plurality of carrier frequencies and a plurality of cells in which a cell and a carrier frequency may be configured as a component carrier, and in which at least two component carriers may be aggregated for communication between the user equipment and the source wireless access node, the aggregated component carriers comprising a primary component carrier and at least one secondary component carrier comprises the step of selecting, at the source wireless access node, a first carrier frequency to be configured as a primary component carrier for communication with the target wireless access node after handover, and selecting, at the target wireless access node, a second carrier frequency to be configured as a secondary component carrier for communication with the target wireless access node after handover.
