Abstract
【解決手段】UEは、LTE無線送受信機、ISMバンドアプリケーション、たとえば、WiFiおよびブルートゥースモジュールを備える。第一方法において、ネットワークは、UE識別により、IDC能力を識別する。第二方法において、UEは、意図的に、非ISM周波数バンド中のセルに、セル選択または再選択を実行する。第三方法において、UEは、能力ネゴシエーションにより、ISMバンドアプリケーションの存在を伝送する。第四方法において、UEは、シグナリングメッセージにより、ISMバンドアプリケーションの起動を伝送する。各種方法中、UEとそのサービングeNBは、FDMまたはTDM方策を適用して、IDC干渉を軽減する。
