Abstract

　端末から基地局へ周期的に報告される受信品質情報に応じて変調及び符号化の方式が選択される移動通信システムにおいて、エラー率の増大を招くことなく、セル間の干渉を考慮してセル端近くに位置する端末の上り送信電力を下げさせる方法。この方法は、第一の基地局が、干渉する端末についての端末識別情報と干渉レベルとを検出して、隣接する全ての基地局装置に対し干渉情報を送信するステップと、該端末を配下に置く第二の基地局が、該干渉情報を受信し、該端末に対し、制御情報を送信するステップと、該端末が、該制御情報を受信し、該干渉レベルに応じて、送信電力を減少させるとともに受信品質情報を品質低下の方向に調整するステップと、を含む。
