Abstract

　システム帯域幅内に離散的に分散した周波数サブキャリアからなる分散型周波数ブロックを割り当てる分散型ＦＤＭＡにより、各ユーザ端末が送信する受信チャネル品質測定用信号が多重され、システム帯域幅は２分木構造が適用され、各分割帯域が２分される無線通信システムの基地局に、各ユーザ端末により通知された、自基地局との間のパスロスに基づいて、各ユーザ端末に割り当てる受信チャネル品質測定用信号の送信帯域幅を決定する手段と、分割帯域のうち、決定された送信帯域幅に対応する分割帯域を割り当て、送信周波数を決定する手段と、送信帯域幅及び送信周波数を各ユーザ端末に通知する手段とを備えることにより達成される。
