Abstract

Le dispositif électronique peut être configuré pour : identifier au moins un premier ensemble de canaux afin d'effectuer une première communication ; identifier au moins un deuxième canal chevauchant le ou les premiers canaux identifiés parmi les canaux pour une deuxième communication ; générer des informations indiquant que le ou les deuxièmes canaux identifiés n'est pas utilisé pour la deuxième communication ; transmettre les informations générées à un dispositif électronique externe ; et effectuer la deuxième communication avec le dispositif électronique externe en utilisant au moins un troisième canal. La deuxième communication est effectuée dans une bande de fréquences qui est la même que la bande de fréquences dans laquelle la première communication est réalisée, et le ou les troisièmes canaux peuvent indiquer au moins un canal restant qui exclut le ou les deuxièmes canaux identifiés parmi les canaux pour la deuxième communication.
