ABSTRACT A method and apparatus for transmitting a control channel in a base station for a wireless communication system. The base station transmits information on a number of channel elements constituting control channels, to a terminal; establishes a set of control channels that the terminal can receive, within the number of channel elements using an identifier (ID) of the terminal; and transmits control information to the terminal through a selected control channel among the control channels. The terminal is restricted to monitor only a proper number of control channels established without the need to monitor all control channels, thereby reducing reception complexity and avoiding unnecessary battery consumption.

La présente invention concerne un procédé et un appareil utilisés pour la transmission d'un canal de commande dans une station de base pour un système de communication sans fil. La station de base transmet, à un terminal, des informations sur un certain nombre d'éléments formant des canaux de commande; établit, à partir des multiples éléments de canaux, un ensemble de canaux de commande que le terminal peut recevoir au moyen d'un identificateur (ID) du terminal; et transmet les informations de commande au terminal par le biais d'un canal de commande sélectionné parmi les canaux de commande. Le terminal est limité afin de ne surveiller qu'un nombre approprié des canaux de commande établi sans qu'il soit nécessaire de surveiller tous les canaux de commande, ce qui réduit ainsi la complexité de la réception et évite la consommation et l'utilisation inutiles de la batterie.
