CA 2547112

According to one aspect of the invention, a method is provided in which a control channel used for transmitting control information is partitioned into a plurality of subchannels each of which is operated at a specific data rate. For each of one or more user terminals, one of the subchannels is selected based on one or more selection criteria for transmitting control information from an access point to the respective user terminal. Control information is transmitted from the access point to a user terminal on a particular subchannel selected for the respective user terminal. At the user terminal, one or more subchannels are decoded to obtain control information designated for the user terminal.

L'invention concerne, selon un aspect, un procédé dans lequel un canal de commande utilisé pour transmettre des informations de commande est partitionné en plusieurs sous-canaux fonctionnant chacun à un débit binaire spécifique. Pour chaque terminal utilisateur, un des sous-canaux est choisi sur la base d'un ou de plusieurs critères de sélection pour transmettre les informations de commande d'un point d'accès au terminal utilisateur respectif. Les informations de commande sont transmises du point d'accès à un terminal utilisateur dans un sous-canal particulier choisi pour le terminal utilisateur respectif. Au niveau du terminal utilisateur, un ou plusieurs sous-canaux sont décodés en vue d'obtenir des informations de commande désignées pour le terminal utilisateur.
