Abstract
【解決手段】チャンネル状態情報(CSI)をマルチプレクシングするユーザ装置(UE)は、CSI報告のための設定情報を受信する送受信機及び設定情報をデコーディングして設定情報によってCSIを計算するプロセッサを含む。送受信機は、アップリンク(UL)チャンネル上で計算されたCSIを送信する。CSIは、N個のセグメントを含み、一つのスロットで送信され、N>1である。N個のうちの第1セグメントはランクインジケーター(RI)及び少なくとも一つの他のCSIパラメーターを含む。基地局(BS)は、CSI報告のための設定情報を生成するプロセッサを含む。BSは、設定情報をUEに送信し、UEから設定情報によって計算されたCSI報告を受信する送受信機をさらに含む。
