A mobile station in a wireless communication network, the mobile station comprising:
- a radio communication unit configured to communicate with a first base station via a plurality of component carriers;
- and
- a control unit configured to control the radio communication unit to initiate a handover procedure to a second base station after receiving at least one handover command for the plurality of component carriers.
A mobile station in a wireless communication network, the mobile station comprising:
- a radio communication unit configured to communicate with a first base station via a plurality of component carriers each having a first cyclic prefix length;
- and
- a control unit configured to control the radio communication unit to initiate a handover procedure from the first base station to a second base station after receiving a handover command,
- wherein, after a handover for one of the plurality of component carriers, the control unit is configured to control the radio communication unit to communicate with the second base station via a component carrier allocated to a time slot different from a time slot to which each of the plurality of component carriers are allocated, and having a second cyclic prefix length different from the first cyclic prefix length.
A base station in a wireless communication network, the base station comprising:
- a radio communication unit configured to communicate with a mobile station via a plurality of component carriers;
- and
- a control unit configured to control the radio communication unit to initiate a handover procedure to a second base station for one of the plurality of component carriers after receiving a report from the mobile station corresponding to the one of the plurality of component carriers.
A base station in a wireless communication network, the base station comprising:
- a radio communication unit configured to communicate with a mobile station via a plurality of component carriers each having a first cyclic prefix length;
- and
- a control unit configured to control the radio communication unit to initiate a handover procedure to a second base station for one of the plurality of component carriers,
- wherein, after a handover for one of the plurality of component carriers, the mobile station communicates with the second base station via a component carrier allocated to a time slot different from a time slot to which each of the plurality of component carriers is allocated, and having a second cyclic prefix length different from the first cyclic prefix length.
A handover method performed by a mobile station in a wireless communication network, the method comprising:
- communicating, by a radio communication unit of the mobile station, with a first base station via a plurality of component carriers;
- and
- initiating, by a control unit of the mobile station, a handover procedure to a second base station after receiving at least one handover command for the plurality of component carriers.
A handover method performed by a mobile station in a wireless communication network, the method comprising:
- communicating, by a radio communication unit of the mobile station, with a first base station via a plurality of component carriers each having a first cyclic prefix length;
- initiating, by a control unit of the mobile station, a handover procedure from the first base station to the second base station after receiving a handover command;
- and
- controlling, by the control unit after a handover for one of the plurality of component carriers, the radio communication unit to communicate with the second base station via a component carrier allocated to a time slot different from a time slot to which each of the plurality of component carriers are allocated, and having a second cyclic prefix length different from the first cyclic prefix length.
A handover method performed by a base station in a wireless communication network, the method comprising:
- communicating, by a radio communication unit of the base station, with a mobile station via a plurality of component carriers;
- and
- initiating, by a control unit of the base station, a handover procedure to a second base station for one of the plurality of component carriers after receiving a report from the mobile station corresponding to the one of the plurality of component carriers.
A handover method performed by a base station in a wireless communication network, the method comprising:
- communicating, by a radio communication unit of the base station, with a mobile station via a plurality of component carriers each having a first cyclic prefix length;
- and
- initiating, by a control unit of the base station, a handover procedure to a second base station for one of the plurality of component carrier;
- wherein, after a handover for one of the plurality of component carriers, the mobile station communicates with the second base station via a component carrier allocated to a time slot different from a time slot to which each of the plurality of component carriers is allocated, and having a second cyclic prefix length different from the first cyclic prefix length.
A non-transitory computer readable medium including computer-program instructions, which when executed by a mobile station in a wireless communication network, cause the mobile station to perform a handover method comprising:
- communicating with a first base station via a plurality of component carriers;
- and
- initiating a handover procedure to a second base station after receiving at least one handover command for the plurality of component carriers.
