Abstract

　ユーザ装置は、複数のアンテナを備え、該複数のアンテナを切替えて上りリンクでリファレンスシグナルを送信する。該複数のアンテナと上りリンクで送信されるサブフレームとが対応付けられている。上りリンクにおいて送信ダイバーシチが適用される無線通信システムにおける基地局装置に、測定された前記リファレンスシグナルの受信レベルを、各ユーザ装置のアンテナ毎に記憶する受信レベル入力手段と、受信レベル記憶手段において記憶された各ユーザ装置のアンテナ毎に送信されたリファレンスシグナルの受信レベルに基づいて、該アンテナと対応付けられたサブフレームに割り当てるユーザ装置を決定するスケジューリングを行うスケジューラとを備える。
