The present disclosure relates to a mobile terminal for performing a handover procedure in a mobile communication system from a source to a target base station. The target base station is configured for the mobile terminal with at least a first and a different second bandwidth part within its cell bandwidth. The mobile terminal comprises: a transceiver which, in operation, receives from the source base station a handover command message including information regarding the configured at least first and second bandwidth part; and a processor which, in operation and upon reception of the handover command message, activates in the transceiver at least a selected one of the configured at least first or second bandwidth part, and controls the transceiver to perform, over the activated at least one of the configured at least first or second bandwidth part, communication with the target base station as part of the handover procedure.
