1. An integrated circuit for controlling a target base station to perform a handover procedure of a user equipment from a source base station, the integrated circuit comprising:
transceiver circuitry, which, in operation, receives from the source base station a handover request message which includes a traffic status of the user equipment and which includes information regarding the user equipment's capability to communicate with the target base station over a first bandwidth part and a second bandwidth part different from the first bandwidth part within a cell bandwidth of the target base station; and
processing circuitry, which, in operation and upon reception of the handover request message, selects a bandwidth part index indicative of the first bandwidth part or the second bandwidth part, controls the transceiver circuitry to configure for the user equipment at least the first bandwidth part and the second bandwidth part, and controls the transceiver circuitry to transmit to the source base station a handover request acknowledge message, wherein the handover request acknowledge message includes information regarding the configured at least first bandwidth part and second bandwidth part which includes the selected bandwidth part index;
wherein the bandwidth part index received by the source base station is transmitted in a handover command message from the source base station to the user equipment to activate the first bandwidth part or the second bandwidth part corresponding to the bandwidth part index, and
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.
