Abstract:
1. A method of establishing multiple links with multiple component carriers for a mobile device of a wireless communication system supporting carrier aggregation, the mobile device being configured with a plurality of component carriers of the wireless communication system for realizing carrier aggregation, the method comprising: establishing a first link corresponding to a first component carrier of the plurality of component carriers, by performing a first radio resource control (RRC) procedure, wherein the type of the first RRC procedure is an RRC connection establishment procedure, a handover procedure or an inter-RAT (Radio Access Technology) handover procedure; and establishing at least a link corresponding to at least a component carrier of the plurality of component carriers other than the first component carrier, by performing a second RRC procedure which is performed according to a first RRC message received in the first link, wherein the type of the second RRC procedure is a RRC connection reconfiguration procedure or a handover procedure, and the first link established by the first RRC procedure and the at least a link established by the second RRC procedure are configured with the same cell radio network temporary identifier (C-RNTI) for PDCCH (Physical Downlink Control Channel) receptions.
