- 基地局と、前記基地局と通信する1個または複数個の端末とを含む時分割多重システムであって、
前記端末は、前記基地局からイニシャルレンジング期間として割り当てられた送信タイミングでレンジング要求メッセージを前記基地局に送信しても前記基地局からこれに対する応答が得られない場合に、前記送信タイミングよりも早く前記レンジング要求メッセージを前記基地局に再送信する第1の送信タイミング変更手段を含むとともに、
前記基地局は、複数の端末に対し予め設定されたデータの送信順序を変更する第2の送信タイミング変更手段を含み、
前記第2の送信タイミング変更手段は、前記端末において前記基地局からのデータの受信時間と前記基地局へのデータの送信時間とが競合する場合に、前記端末に対する送信データ領域を予め設定したデータ領域よりも前方にマッピングすることを特徴とする時分割多重システム。 - 基地局と、前記基地局と通信する1個または複数個の端末とを含む時分割多重システムにおける送信タイミング制御方法であって、
