Claims (1)

  1. TDD/CDMA-Endgerät, das folgendes umfasst:
    eine Empfänger- und Beurteilungsvorrichtung für den Sendeleistungsbefehl zum Empfang eines Sendeleistungsbefehls und zur Bestimmung eines Werts des empfangenen Sendeleistungsbefehls, wobei der Sendeleistungsbefehl eine Erhöhung oder Verringerung der Sendeleistung anzeigt;
    eine Antenne zum Empfang eines Referenzsignals und zur Abstrahlung einer Kommunikation, wobei das Referenzsignal in einem TDD/CDMA-Format übertragen wird;
    eine Messvorrichtung für die Referenzsignalleistung zum Messen eines empfange­ nen Leistungspegels des Referenzsignals;
    eine Vorrichtung zur Bestimmung einer Ausbreitungsdämpfung zum Vergleichen des gemessenen empfangenen Leistungspegels des Referenzsignals mit einem Sendeleis­ tungspegel des Referenzsignals, um eine Schätzung der Ausbreitungsdämpfung des Refe­ renzsignals zu erzeugen;
    eine Vorrichtung zur Bestimmung der Sendeleistungsregelung zum Bestimmen einer Größe einer Änderung des Sendeleistungspegels unter Verwendung der erzeugten Schätzung der Ausbreitungsdämpfung und zur Bestimmung einer Einstellung eines Über­ tragungsleistungspegels als Reaktion auf den Sendeleistungsbefehl im Umfang der bestimmten Größenänderung;
    eine Modulations- und Spreizvorrichtung zur Erzeugung der Kommunikation in einem TDD/CDMA-Format; und
    einen Verstärker zum Einstellen eines Übertragungsleistungspegels der Kommuni­ kation auf der Grundlage der Einstellung des Übertragungsleistungspegels.
