Abstract

　受信品質情報の総通知量を抑えながら、通信制御装置における適応変調および適応スケジューリングを効率的に行なう。少なくとも１つのサブキャリアからなる複数のチャネルのうち、通信相手によって割り当てられたチャネルで信号を受信し、受信した信号の受信品質を測定し、受信品質情報を前記通信相手に通知するマルチキャリア通信方式に適用される通信端末装置３００であって、各サブキャリアの受信品質を測定する受信品質測定部３０８と、前記通信相手に対する各チャネルの割り当て要求度を決定し、前記割り当て要求度に基づいてチャネル毎に受信品質情報を表すための情報量を選択し、前記測定した受信品質に基づいて、前記選択した情報量で表わされる前記受信品質情報を生成する受信品質情報生成部３０９と、を備える。
