Abstract:
(EN) In a system in which the transmission bandwidth is variable, transmission power is controlled in such a manner that minimizes impact on a circuit as much as possible. Provided is a transmission power control method applied to a transmitter that transmits data by using different transmission formats in different transmission occasions, wherein: the transmission power is controlled according to the transmission formats before digital-analogue conversion is applied to data to be transmitted; and, based on the transmission power control, the transmission power is controlled for the data to be transmitted to which the digital-analogue conversion has been applied. Each of the transmission formats is provided to define a frequency bandwidth used for transmission of data to be transmitted.
(FR) Dans un système dans lequel la bande passante de transmission est variable, la puissance de transmission est commandée de manière à réduire à un minimum un impact sur un circuit autant que possible. L'invention concerne un procédé de commande de puissance de transmission appliqué à un émetteur qui transmet des données en utilisant différents formats de transmission à différentes occasions de transmission. Dans le procédé : la puissance de transmission est commandée en fonction des formats de transmission avant qu'une conversion numérique-analogique ne soit appliquée aux données à transmettre ; et, sur la base de la commande de puissance de transmission, la puissance de transmission est commandée pour les données à transmettre auxquelles la conversion numérique-analogique a été appliquée. Chacun des formats de transmission est fourni pour définir une largeur de bande de fréquence utilisée pour la transmission des données à transmettre.
(JA)  可変送信帯域幅のシステムにおいて、回路へのインパクトをできるだけ小さくする送信電力制御を行なう。送信機会毎に異なる送信フォーマットを用いてデータを送信する送信装置に適用される送信電力制御方法であって、送信データに対してディジタル/アナログ変換を行なう前に、前記送信フォーマットに応じて送信電力を制御し、前記送信電力制御に基づいて、前記ディジタル/アナログ変換後の送信データに対して、送信電力を制御する。また、前記送信フォーマットは、送信データの送信に用いる周波数帯域幅を定めたものである。
