Abstract
(EN)
A radio device (10) capable of shifting, in accordance with a wake-up signal, from a power saving state with lower power consumption than an activation state to the activation state, the wake-up signal including a determination field for determining whether the radio device (10) that has received the wake-up signal operates as a relay terminal or operates as a slave terminal. The radio device (10) is characterized by being provided with a control unit (107) which, upon receiving the wake-up signal addressed to the radio device (10), determines from the determination field whether the radio device (10) operates as a relay terminal or operates as a slave terminal.
(FR)
L'invention concerne un dispositif radio (10) capable de décaler, conformément à un signal de réveil, d'un état d'économie d'énergie avec une consommation d'énergie inférieure à un état d'activation vers l'état d'activation, le signal de réveil comprenant un champ de détermination pour déterminer si le dispositif radio (10) qui a reçu le signal de réveil fonctionne comme un terminal relais ou fonctionne comme un terminal esclave. Le dispositif radio (10) est caractérisé en ce qu'il comporte une unité de commande (107) qui, lors de la réception du signal de réveil adressé au dispositif radio (10) détermine à partir du champ de détermination si le dispositif radio (10) fonctionne comme un terminal relais ou fonctionne comme un terminal esclave.
(JA)
ウェイクアップ信号に応じて、起動状態よりも消費電力が低い省電力状態から前記起動状態に移行することが可能な無線装置(10)であって、ウェイクアップ信号は、当該ウェイクアップ信号を受信した無線装置(10)が中継端末として動作するか子機端末として動作するかを判定するための判定フィールドを含み、無線装置(10)宛てのウェイクアップ信号を受信すると、判定フィールドから無線装置(10)が中継端末として動作するか子機端末として動作するかを判定する制御部(107)、を備えることを特徴とする。
