Abstract
【解決手段】ソフト・ハンド・オフのモードで動作中に、移動局装置が複数の基地局と通信し、複数の基地局の各々からNACKおよびACK信号の形で複数のフィードバック信号を受信する。移動局装置はこれらフィードバック信号の各々の信頼性を判定し、信頼性のある信号を合成し、もしもACK信号が受信されなければ古い情報を再送信する。他方で、1つでも信頼性のあるACK信号を受信することは結果として、新たなデータが複数の基地局へと配信されることにつながる。
【選択図】 図1A
Description
添付の図面と関連付けて為される以下の説明を参照することによって本発明は理解されることが可能であり、図中では類似した参照番号は類似した素子を特定している。
SIR≧SIRThd........信頼性のあるリンク
SIR≦SIRThd........信頼性のないリンク
ここでSIRThdはSIR信頼性の大きさの閾値であり、無線リンクの設定および現場のRF最適化に基づいて最適化される。いったんその無線リンクが信頼性のあるリンクと見なされると、特定の基地局から得たACK/NACK情報が合成に使用されることが可能である。
