Claims (9)
- 無線ネットワークで動作可能なトランシーバを含む装置であって、
前記トランシーバは、リファレンス基地局(BS)でのスケジューリングされた上りリンク(UL)送信が移動局(MS)からの上りリンク(UL)リファレンス信号と干渉することを回避することにより、前記無線ネットワークでの位置決定を最適化するように構成される装置。 - 前記位置決定は、上りリンク到達時間差(TDOA)により実現される、請求項1に記載の装置。
- 前記リファレンスBSは、どのシンボル及び周波数オフセットについて前記MSからの前記ULリファレンス信号送信が生じるかを位置コントローラ(LC)から事前に認識しているため、前記リファレンスBSのスケジューラは、この時間及び周波数オフセットで何かをスケジューリングすることを回避することができ、これにより、前記リファレンスBSは、前記MSからの前記ULリファレンス信号を受信するのに十分に準備することができ、高い精度でこの信号を復号/測定することができる、請求項2に記載の装置。
- リファレンス基地局(BS)でのスケジューリングされた上りリンク(UL)送信が移動局(MS)からの上りリンク(UL)リファレンス信号と干渉することを回避することにより、無線ネットワークでの位置決定を最適化するように、無線ネットワークで動作可能なトランシーバを構成することを有する方法。
- 上りリンク到達時間差(TDOA)により前記位置決定を実現することを更に有する、請求項4に記載の方法。
- どのシンボル及び周波数オフセットについて前記MSからの前記ULリファレンス信号送信が生じるかを、前記リファレンスBSにより位置コントローラ(LC)から事前に認識しているため、前記リファレンスBSのスケジューラは、この時間及び周波数オフセットで何かをスケジューリングすることを回避することができ、これにより、前記リファレンスBSは、前記MSからの前記ULリファレンス信号を受信するのに十分に準備することができ、高い精度でこの信号を復号/測定することができることを更に有する、請求項5に記載の方法。
- アクセスされたときに、機械に動作を実行させる命令を提供する機械アクセス可能媒体であって、
前記命令は、リファレンス基地局(BS)でのスケジューリングされた上りリンク(UL)送信が移動局(MS)からの上りリンク(UL)リファレンス信号と干渉することを回避することにより、無線ネットワークでの位置決定を最適化するように、無線ネットワークで動作可能なトランシーバを構成することを有する機械アクセス可能媒体。 - アクセスされたときに、上りリンク到達時間差(TDOA)により前記位置決定を実現することを更に有する命令を更に有する、請求項7に記載の機械アクセス可能媒体。
- アクセスされたときに、どのシンボル及び周波数オフセットについて前記MSからの前記ULリファレンス信号送信が生じるかを、前記リファレンスBSにより位置コントローラ(LC)から事前に認識しているため、前記リファレンスBSのスケジューラは、この時間及び周波数オフセットで何かをスケジューリングすることを回避することができ、これにより、前記リファレンスBSは、前記MSからの前記ULリファレンス信号を受信するのに十分に準備することができ、高い精度でこの信号を復号/測定することができることを更に有する命令を更に有する、請求項8に記載の機械アクセス可能媒体。
