Abstract

　本発明は、基地局（ＢＳ）と無線端末（ＵＥ）との間での通信時に、上り方向の通信レートが下り方向の通信レートよりも小さくなるような状況において、ＵＥ（１）のバッファがオーバーフローを起こさないようにしたもので、このために、少なくとも１つのＢＳ（３０）からの下りデータチャネル（HS-PDSCH）を受信し、当該下りデータチャネル（HS-PDSCH）に関する受信品質情報（ＣＱＩ）を算出して前記ＢＳ（３０）へ報告するＵＥ（１）の通信制御方法であって、ＵＥ（１）が、ＢＳ（３０）への上りデータチャネル（E-DCH）の送信レートを監視し、その監視結果に応じて、算出された受信品質情報（ＣＱＩ）を低下制御する。
