Description
Y=(X+C+T)×3
Tは符号化前にコードブロックの末尾に連結されるテールビット数で、T=8[ビット]であり、全ビットの値が0に固定されている。
KX={(X+C+T)×3}/(X+C)
ここで音声が無音状態(X=0)となった場合、符号化利得は以下の式のようになる。
K0={(C+T)×3}/C
RNC 無線ネットワーク制御装置
SIR 信号電力対干渉電力比
TFI トランスポートフォーマット指標
Claims (1)
- 移動端末装置と基地局装置との間の無線接続において、複数の無線アクセスベアラがマッピングされた物理チャネルについて、基地局装置側における該複数の無線アクセスベアラの1つの受信品質を基に、移動端末装置の送信電力制御用の基準値を制御する送信電力制御装置であって、
前記受信品質の監視対象の無線アクセスベアラが、無音状態の音声伝送無線アクセスベアラであるか否かを、多重化情報を基に判定する無音状態判定手段と、
前記受信品質の監視対象の無線アクセスベアラが、無音状態の音声伝送無線アクセスベアラであると判定された場合に、受信品質の監視対象の無線アクセスベアラを、無音状態の音声伝送無線アクセスベアラ以外の他の無線アクセスベアラに切替える手段とを備え、 無音状態の音声伝送無線アクセスベアラ以外の無線アクセスベアラの受信品質を基に移動端末装置の送信電力制御用の基準値を制御することを特徴とする移動通信システムにおける送信電力制御装置。
