Abstract
【解決手段】チャネル状態情報が、複数のコンポーネント・キャリアまたはサービング・セルのための、周期的な報告および非周期的な報告で報告される。チャネル状態情報は、統合されたダウンリンク・キャリアまたはサービング・セルのサブセットについて報告され得る。非周期的な報告では、チャネル状態情報が報告されるキャリア/サービング・セルは、非周期的な報告の要求に基づいて決定される。CQI/PMI/RIの報告およびHARQ ACK/NACKの報告が1つのサブフレームで同時に起きる場合、HARQ ACK/NACKの報告はPUCCHで送信され、CQI/PMI/RIの報告はPUSCHで送信される。
