Abstract
【解決手段】データ・キャリア(DC−A,DC−B)を整理分類する方法であって、この方法は、キャリア信号(RF)の伝送の間に通信局(STATION)にデータ(ID)を供給するために時間的な開始点(0,t4)に関する複数の伝送開始時間から前記キャリア信号(RF)の伝送を開始する伝送開始時間を選択するステップと、前記時間的な開始点(0,t4)の後で前記選択された伝送開始時間に先立って他のデータ・キャリア(DC−A,DC−B)がキャリア信号を既に伝送しているかをテストするステップと、前記テストの結果が肯定的な場合に前記選択された伝送開始時間における前記キャリア信号(RF)の前記伝送の開始を阻止するステップと、を備える。

Claims (8)
- データ・キャリアを整理分類する方法であって、
キャリア信号の伝送の間に、前記データ・キャリアの整理分類を可能にするデータを通信局へ供給するために、時間的な開始点に関する複数の伝送開始時間から、前記キャリア信号の伝送を開始する伝送開始時間を選択するステップと、
前記時間的な開始点の後で前記選択された伝送開始時間の前に、他のデータ・キャリアがキャリア信号を既に伝送しているかどうかをテストするステップと、
前記テストの結果が肯定的な場合に、前記選択された伝送開始時間における前記キャリア信号の前記伝送の開始を阻止するステップと、
を備える方法。 - 前記テストの前記結果が否定的な場合に前記選択された伝送開始時間に前記キャリア信号の伝送を開始するステップを備える請求項1に記載の方法。
- 前記データの供給が行なわれる前に、時間的なデータ・フリー・プレデータ供給期間を、前記キャリア信号伝送の間、持続させるステップと、
前記データの供給が行なわれた後で前記キャリア信号の伝送の終了まで時間的なデータ・フリー・ポストデータ供給期間を、前記キャリア信号伝送の間、持続させるステップと、
を備える請求項2に記載の方法。 - 前記伝送開始時間はランダムな原則によって選択される請求項1に記載の方法。
- 前記伝送開始時間を選択することは、データ・キャリアの数よりも大きな数の伝送開始時間を選択可能にさせる請求項1に記載の方法。
- 前記伝送開始時間を選択することは、時間の前記開始点が前記通信局のキャリア信号伝送の終了として定義され、前記通信局には、そのキャリア信号伝送の間の整理分類コマンドを表示するそのデータが供給されるようにして実行される請求項1に記載の方法。
- 前記伝送開始時間を選択することは、前記通信局のキャリア信号伝送の前記終了についての選択可能な離散的遅延時間により、前記伝送開始時間を時間的にシフトさせることを含む請求項1に記載の方法。
- 識別データとしてのそのデータが供給されている前記データ・キャリアを、前記通信局により、キャリア信号が伝送されていない初期状態に設定するステップを備える請求項2に記載の方法。
