Method, base station, terminal and communication system for updating component carrier

An electronic device, comprising:

• circuitry configured to
• communicate with a base station via at least one component carrier;
• acquire a plurality of location points of the electronic device at different moments of time;
• determine a speed and a moving direction of the electronic device based on the plurality of the location points and the different moments of time;
• report the speed and the moving direction of the electronic device to the base station for the base station to determine whether the electronic device has left a service area of the at least one component carrier and, if so, to determine a candidate component carrier to serve the electronic device as a secondary component carrier together with the at least one component carrier in a carrier aggregation communication, based on the speed and the moving direction of the electronic device, wherein the candidate component carrier services another service area located in the moving direction of the electronic device;
• receive radio resource control reconfiguration information from the base station, the radio resource control reconfiguration information including radio resource configuration information of the candidate component carrier;
• configure the candidate component carrier as the secondary component carrier;
• and
• in a case that the electronic device accesses the candidate component carrier, deactivate the at least one component carrier or handover the at least one component carrier.

A method of an electronic device, the method comprising:

• communicating with a terminal device via at least one component carrier;
• acquiring a plurality of location points of the terminal device at different moments of time;
• determining, using circuitry of the electronic device, a speed and a moving direction of the terminal device based on the plurality of the location points and the different moments of time;
• and
• in a case that the terminal device has left a service area:
• determining, using the circuitry, a candidate component carrier to serve the terminal device as a secondary component carrier together with the at least one component carrier based on the speed and the moving direction of the terminal device in a carrier aggregation communication, wherein the candidate component carrier services another service area located in the moving direction of the terminal device;
• and
• in a case that the terminal device accesses the candidate component carrier, deactivating the at least one component carrier or performing a handover the at least one component carrier.
