1. A user equipment for performing a handover procedure in a mobile communication system from a source base station to a target base station, the user equipment comprising:
a transceiver which, in operation, receives from the source base station a handover command message including a bandwidth part index indicative of a first bandwidth part or a second bandwidth part different from the first bandwidth part within a cell bandwidth of the target base station, wherein the target base station is configured for the user equipment with at least the first bandwidth part and the second bandwidth part; and
a processor which, in operation and upon reception of the handover command message, activates in the transceiver the first bandwidth part or the second bandwidth part indicated by the bandwidth part index, and controls the transceiver to perform, over the activated first bandwidth part or the activated second bandwidth part, communication with the target base station as part of the handover procedure;
wherein the handover command message includes a specific sequence of information, and the bandwidth part index to activate the first bandwidth part or the second bandwidth part is included at a specific position in the specific sequence.
