Abstract
【解決手段】無線CDMA通信システムの逆方向リンクにおいて、フィールド・ユニットと送受信基地局の間のアイドル・モード・コネクションが提供され、フィールド・ユニット識別子を用いて、モジュロ関数に基づきタイム・スロットまたはフレーム・オフセットを計算する。これにより、フィールド・ユニット・メンテナンス伝送を有効なスロットまたはオフセット間に分配する。別の好ましい実施形態では、物理層の明示的な信号状態変化を検出し、電力目標値を変化させる。さらに別の実施形態では、フィールド・ユニットとBTSの間で調整される、所定の時間期間の間にメンテナンス・データを伝送することにより、電力レベルを調整する。
【選択図】図11
Description
合、アクセス端末24はアイドルのデータ送信状態に入るかまたはアイドルのデータ伝送状態を維持する。伝送を待つデータが存在する場合、アクセス端末24はアクティブのデータ伝送状態に入るかまたはアクティブのデータ伝送状態を維持する。
判断されたデータ伝送状態を検査するためにチェックを実行する。データ伝送状態がアイドルである場合、基地局は新しいアイドル目標電力レベルを計算または維持する。データ伝送状態がアクティブである場合、基地局は新しいアクティブ目標電力レベルを計算する。次に、基地局20は計算した目標電力レベルを示す電力制御メッセージをアクセス端末24に送信する。
20 受信基地局
24 フィールド・ユニット
50 逆方向リンク
