Claims (4)
- 移動局であって、
第1セルにおいて接続状態にある場合で、第2セルにおけるランダムアクセス手順の開始トリガを検出した場合で、かつ、該第1セルにおいて上り信号が送信されていると判断した場合に、該ランダムアクセスプリアンブルの送信を延期するように構成されている送信部を具備しており、
前記送信部は、前記第1セルにおける上り信号の送信が完了した際に、延期されている前記ランダムアクセスプリアンブルの送信を行うように構成されていることを特徴とする移動局。 - 前記送信部は、前記ランダムアクセスプリアンブルの送信を延期してから所定期間が経過した場合、該ランダムアクセスプリアンブルの送信を中止するように構成されていることを特徴とする請求項1に記載の移動局。
- 前記送信部は、所定回数、前記第2セルにおけるランダムアクセスプリアンブルの送信を延期した場合には、次に、該第2セルにおけるランダムアクセス手順の開始トリガを検出した際に、前記第1セルにおいて上り信号が送信されていると判断した場合であっても、該第2セルにおけるランダムアクセスプリアンブルの送信を延期することなく行うように構成されていることを特徴とする請求項2に記載の移動局。
- 前記送信部は、前記第1セルにおいて接続状態にある場合で、前記第2セルにおけるランダムアクセス手順の開始トリガを検出した場合で、該第1セルにおいて上り信号が送信されていると判断した場合で、かつ、前記ランダムアクセスプリアンブル及び該上り信号の送信に十分な送信電力を確保することができない場合に、該ランダムアクセスプリアンブルの送信を延期するように構成されていることを特徴とする請求項2に記載の移動局。
