Abstract:
1. An electronic device for use in a user equipment of a communication system supporting carrier aggregation, comprising: circuitry configured to receive first information transmitted to the user equipment via a first cell in response to a change in system information of the communication system, wherein the first cell is one cell to which the user equipment is connected and corresponds to a component carrier which is being used by the user equipment and is kept in connection with a base station of the communication system, wherein the change in system information comprises different system information for another component carrier of a second cell that also communicates with the user equipment while the first cell is communicating with the user equipment to increase the communication channel capacity to the user equipment, the first information comprises system information associated with the another component carrier, the first information further comprises system information comprising configuration information on downlink transmission bandwidth and information indicating downlink carrier frequency associated with the another component carrier, wherein the circuitry is configured to received additional information from the first cell while also receiving information from the second cell.
