Abstract

　本発明に係る無線通信システムは、基地局上位装置（２）と、複数の基地局（３）とを備えており、基地局（３）が有する伝送遅延許容範囲（Ｔｔｗ）から外れた受信タイミングで基地局（３）がユーザデータ（ＵＤ２）を受信した場合には、基地局上位装置（２）からのユーザデータ（ＵＤ２）の送信タイミングを調整する。また、基地局（３）は、ユーザデータ（ＵＤ２）の受信タイミングと受信タイミングの回数を、所定の期間測定することにより、受信タイミング分布を測定する、受信タイミング分布測定部（３１）と、受信タイミング分布に基づいて、伝送遅延許容範囲（Ｔｔｗ）を変更することができる伝送遅延許容範囲変更部（３２）とを、備えている。
