Abstract
【解決手段】eMBB WTRUは、PDCCHプリエンプションインジケーターを含むCORESETのためのeMBB CORESETコンフィギュレーションを受信し得る。PDCCHプリエンプションがPDCCHプリエンプションインジケーターに基づいて有効であるならば、eMBB WTRUは、eMBB CORESETにおける各REGバンドルに対してチャネル推定値を比較することによってeMBB CORESETにおけるプリエンプトされたREGを識別し取り除き得る。WTRUは、eMBB CORESETにおける残りのREGに基づいてチャネル推定を行い、受信信号に基づいてeMBB CORESETにおける残りのREGにブラインドデコーディングを行うことによってPDCCHを検出し得る。
