Description
また、本発明の無線通信システムにおいてサービングセルまたは隣接セルを測定する端末は、基地局と信号を送受信し、前記サービングセルまたは隣接セルに対する測定を行う送受信機と、前記サービングセルまたは隣接セル測定のためのパターン情報を含むRRC連結再設定メッセージを基地局から受信し、前記RRC連結再設定メッセージで指示する測定対象に対して前記パターン情報を利用して前記サービングセルまたは隣接セルを測定し、前記測定結果を前記基地局に報告するように制御する制御部とを含むことを特徴とする。
−パターン2:carrierFreqに指示された周波数で隣接セルに対するRRM測定時に、ABS位置指示
−パターン3:サービングセルに対してCSI測定が制限されないサブフレーム位置指示。パターン1、2とは異なって、2つのパターンが提供される。
言い換えれば、RRC連結再設定メッセージのmeasSubframePatternConfigNeighl IEが設定である場合は、パターン2によって、前記RRC連結再設定メッセージに含まれたパターン情報を利用して隣接セルを測定するように指示したものと解釈されることができる。
