AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-22 is confirmed.
1. A method of Secondary Cell (SCell) release during handover comprising:
configuring at least one SCell by a source eNB to a User Equipment (UE); and
including information by the source eNB in a HandoverPreparationInformation message for a target eNB to control SCell release in the UE during a handover,
wherein the information indicates SCell indexes of all SCells configured to the UE before the handover, thereby allowing the target eNB to include a sCellToReleaseList with all the SCells configured to the UE in a handover command for the UE to release the SCells included in the sCellToReleaseList.
