隨著使用者對高品質傳輸服務的追求，行動通訊的研究朝著高頻譜使用率的方向發展，除了開發更快速的下載傳輸速率的技術之外，群體廣播是另外一種有效的解決方案，因為它能同一時間將資訊藉由廣播傳遞到多個使用者，通常是使用在串流媒體以及網路電視的應用上。這項技術可以在同一時間槽內重複利用頻寬，縮減網路資源的使用量。
在這篇論文中，我們以一種串流的觀點設計群體廣播的排程方法，不再以封包的方式來傳遞資訊，而是將其視為一條位元串流；利用這樣的一種模型運行在CDMA2000的模擬環境下，我們提出一種在媒介存取控制層(Medium Access Control Layer)運行的無線群體廣播排程方法來優化可使用頻寬(Available Bandwidth)的利用率。簡單的來說，我們不只是使得每一次的傳輸讓最多的使用者收到，而是希望每一次的排程能夠讓輸出最大化。在使用者可能忍受的延遲範圍內，讓信號不良的群體等待，留至稍後信號轉佳再為其服務，希望頻寬利用率能因此得到提升。以下我們將主要考慮在無線資料下載的服務上，因為在這種情況下的使用者通常需求的是同一份資訊，我們也把傳統的無線廣播排程與我們的方法作比較。模擬與實驗的結果顯示有彈性的批次傳輸對於信號普遍不佳的使用者群體有相當的助益。
