マルチユーザ複数入力複数出力のための、干渉測定およびチャネル状態情報フィードバック
Document Type and Number:
Japanese Patent JP2020520151
Kind Code:
A
Abstract:
無線ネットワークにおけるチャネル状態情報（ＣＳＩ）フィードバックの方法および装置。ある実施の形態では、方法は、チャネル測定用の第１非ゼロ電力（ＮＺＰ）ＣＳＩ参照信号（ＲＳ）設定と、第２ＮＺＰ ＣＳＩ−ＲＳ設定と、干渉測定用のＣＳＩ干渉測定（ＣＳＩ−ＩＭ）設定と、を含むシグナリングを受信することを含む。方法は、ＣＳＩフィードバック要求を受信することと、少なくとも、シグナリングされた第１ＮＺＰ ＣＳＩ−ＲＳ設定と、第２ＮＺＰ ＣＳＩ−ＲＳ設定と、ＣＳＩ−ＩＭ設定と、に基づいてＣＳＩを推定することと、を含む。【選択図】図１２
