Abstract

　通信システムは、基地局１０～１６を構成するセクタユニットおよびそのセクタユニットに対応したセクタ４，５内にそれぞれ存在する移動局２，３を含む。移動局２，３は、セクタ４，５に対応したセクタユニットおよびこのセクタ４，５に隣接するセクタ４，５に対応したセクタユニットに伝送路情報信号を送信する。セクタユニットは、そのセクタユニットに対応したセクタ４に存在する当該移動局２から受信した伝送路情報信号、およびそのセクタユニットに対応したセクタ４に隣接する隣接セクタ５に存在する隣接移動局３から受信した伝送路情報信号に基づいて、当該移動局２に指向し隣接移動局３に指向しない送信ビームを用いてデータを当該移動局２に送信する。こうした構成によって、隣接するセクタからの干渉を回避することができる。
