Abstract
(EN)
[Problem] To reduce the power consumed by a terminal. [Solution] An integrated circuit for wireless communication according to an embodiment of the present invention is provided with a baseband integrated circuit. The baseband integrated circuit receives, via an RF integrated circuit, a first frame requesting transmission permission. If the destination of the first frame is not the device itself, the baseband integrated circuit performs control to suppress transmission. Even if a second frame notifying the transmission permission has not been received after a first time has elapsed since the first frame was received, the baseband integrated circuit continues to suppress the transmission.

Le problème décrit par la présente invention a pour but de réduire l’énergie consommée par un terminal. La solution selon l'invention, conformément à un mode de réalisation, concerne un circuit intégré pour une communication sans fil qui comporte un circuit intégré de bande de base. Le circuit intégré de bande de base reçoit, par l’intermédiaire d’un circuit intégré radiofréquence (RF), une première trame demandant une autorisation de transmission. Si la destination de la première trame n’est pas le dispositif lui-même, le circuit intégré de bande de base réalise une commande pour supprimer la transmission. Même si une seconde trame notifiant l’autorisation de transmission n’a pas été reçue après qu’un premier temps s’est écoulé depuis que la première trame a été reçue, le circuit intégré de bande de base continue à supprimer la transmission.
