Abstract
【解決手段】UEがセルエッジにある場合に帯域幅を向上させるために、データが、複数の基地局を使用してユーザ機器に送信されるように分割されることが可能であり、またはハンドオーバを向上させるためにユーザ機器によって、複数の基地局に送信されるように分割されることが可能である。データ分割は、ユーザ機器上、または基地局上のパケットデータコンバージェンスプロトコル層、無線リンク制御層、または媒体アクセス制御層において実行されることが可能である。データは、X2インターフェース負荷またはX2インターフェース遅延キャリア集約を低減するために、サービングゲートウェイなどのネットワークノードにおいて、代わりに分割されてもよい。
