WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION BASE STATION AND WIRELESS COMMUNICATION SYSTEM
First Claim
1. A wireless communication apparatus that can communicate with a wireless communication base station using component carriers of a plurality of communication cells managed by the wireless communication base station at the same time, comprising:
- a receiving section that receives a reference signal transmitted from the wireless communication base station in each of the communication cells;
a radio condition determining section that determines a radio condition of the wireless communication apparatus on the basis of the reference signal received by the receiving section;
a report creating section that creates a report to be transmitted to the wireless communication base station on the basis of the determination result of the radio condition determining section; and
a transmitting section that transmits the report to the wireless communication base station,wherein the radio condition determining section includes a physical layer problem determining section which determines whether a physical layer problem occurs in each component carrier used or can be used in communication between the wireless communication apparatus and the wireless communication base station;
wherein when the physical layer problem determining section determines that the physical layer problem occurs in some of the plurality of component carriers used in the communication between the wireless communication apparatus and the wireless communication base station, the radio condition determining section notifies the component carrier in which the physical layer problem occurs to the report creating section; and
wherein the report creating section creates a report corresponding to the component carrier in which the physical layer problem occurs and a predetermined criterion.

Abstract
A wireless communication apparatus can communicate with a wireless communication base station using component carriers of communication cells managed by the wireless communication base station simultaneously. A radio condition determining section includes a physical layer problem determining section that determines whether a physical layer problem occurs in each component carrier which is used or can be used in communication between the wireless communication apparatus and the wireless communication base station. When it is determined that the physical layer problem occurs in some of the component carriers used in the communication, the radio condition determining section notifies the component carrier in which the physical layer problem occurs to a report creating section. The report creating section creates a report corresponding to the component carrier in which the physical layer problem occurs and a predetermined criterion.
