Abstract
Description
Claims (7)
- ブロードキャストまたはマルチキャストにおける移動端末機器のための隣接セル選択方法において、
各隣接セルごとにセル品質推定値を導出し、求められた品質を許容可能な最低品質と比較し、
提示された許容可能な隣接セルのうち最高品質をもつ隣接セルを選択し、
共通のパイロットチャネル(CPICH)の送信電力と2次的な共通のコントロール物理チャネル(S−CCPCH)の送信電力との差分を表すパラメータを、マルチメディア・ブロードキャスト・マルチキャスト・サービス(MBMS)コントロールチャネルを介して前記移動端末機器へ伝送し、
該移動端末機器はセル品質の推定値を導出することを特徴とする、
隣接セル選択方法。 - 請求項1記載の方法において、
前記移動端末機器は前記共通のパイロットチャネルにおける信号対干渉比(SIR)を推定し、該比を伝送されたパラメータに従いスケーリングすることを特徴とする方法。 - 請求項1記載の方法において、
前記移動端末機器は、ブロードキャストまたはマルチキャストのデータストリームを搬送する物理チャネルの送信に使用されるネットワーク電力の合成からセル品質の推定値を導出し、該推定値は、主パイロット物理チャネルの電力およびシグナリングされたパラメータ、拡散率、コードパンクチャリングリミットおよび移動端末機器と隣接セルとの間の伝送経路損失から導出されることを特徴とする方法。 - 請求項3記載の方法において、
前記伝送経路損失は、測定された共通のパイロット参照チャネルの受信電力と共通のパイロットチャネルの送信電力との差分として、前記パラメータに従いスケーリングされて推定されることを特徴とする方法。 - 請求項1から4のいずれか1項記載の方法において、
選択された隣接セルはサービスセルと同期がとられており、個々の伝送が無線リンクコントロール合成機能におけるウィンドウサイズよりも時間的に逸脱しないことを特徴とする方法。 - 請求項1から5のいずれか1項記載の方法において、
1つのセルグループ内のいずれか2つのセル間の最大タイミング差分はまえもって定められた値を超えないことを特徴とする方法。 - 請求項1から6のいずれか1項記載の方法において、
サービスセルのMBMSトラフィックチャネル品質が品質条件を下回ったときのみ、移動端末機器は隣接セルの選択を行うことを特徴とする方法。
