Abstract
(EN)
One embodiment pertains to a base station device included in a wireless communication system which has a plurality of terminal devices and the base station device, which wirelessly communicates with each of the plurality of terminal devices, the base station device being configured so as to have: a group determination unit for dividing the plurality of terminal devices into one or more terminal groups; a request receiving unit for receiving from a first terminal device a system information notification request requesting that the base station device provide a notification about system information which the first terminal device uses when communicating; and a system information notification unit which, in response to the received system information notification request, notifies the terminal devices in the first terminal group to which the first terminal device belongs of the request system information.
(FR)
L'invention concerne, dans un mode de réalisation, un dispositif de station de base compris dans un système de communication sans fil qui est doté d'une pluralité de dispositifs terminaux et du dispositif de station de base, lequel communique sans fil avec chaque dispositif de la pluralité de dispositifs terminaux, le dispositif de station de base étant configuré de façon à comprendre: une unité de détermination de groupes servant à diviser la pluralité de dispositifs terminaux en un ou plusieurs groupes de terminaux; une unité de réception de demandes servant à recevoir en provenance d'un premier dispositif terminal une demande de notification d'informations de système demandant que le dispositif de station de base fournisse une notification concernant des informations de système que le premier dispositif terminal utilise lorsqu'il communique; et une unité de notification d'informations de système qui, en réponse à la demande reçue de notification d'informations de système, notifie les informations de système de la demande aux dispositifs terminaux du premier groupe de terminaux auquel appartient le premier dispositif terminal.
