Abstract
Description
本発明の好ましい実施例に従って、順方向誤り符号化を動的に割り当てる方法が提供される。本方法は、データを伝送するための帯域幅の利用を監視し、データ用の帯域幅の利用に基づいて、順方向誤り符号化のレベルを動的に調節して、利用されていない利用可能な帯域幅を実質的に占有する。
Claims (6)
- 順方向誤り符号化を動的に割り当てるための方法(400)であって、
送信されるデータについての帯域幅の利用を監視するステップ(402)と、
帯域幅の前記利用に応答して、利用されていない帯域幅が実質的に占有されるように、順方向誤り符号化のレベルを調節するステップ(408)とを含む方法。 - 順方向誤り符号化のレベルの調節を自動的に検出するステップ(414)をさらに含む請求項1に記載の方法。
- 前記監視するステップは、送信バッファ内の前記データを監視するステップ(402)を含む請求項1に記載の方法。
- 前記調節するステップは、
帯域幅の前記利用が増加する場合に順方向誤り符号化のレベルを下げるステップ(408)と、
帯域幅の前記利用が減少する場合に順方向誤り符号化のレベルを上げるステップ(408)とをさらに含む請求項1に記載の方法。 - 使用すべき順方向誤り符号化の最小限のレベルを設定するステップ(406)を更に含む請求項1に記載の方法。
- 最悪の場合の帯域幅シナリオに基づいて順方向誤り符号化の最小限のレベルを設定するステップ(406)をさらに含む請求項1に記載の方法。
