Abstract

La présente invention concerne un procédé et un dispositif pour indiquer un canal de travail indésirable. Le procédé consiste à : déterminer un canal de travail indésirable, le canal de travail indésirable étant un canal dont on ne souhaite pas qu'il fonctionne en raison d'une distorsion d'intermodulation; générer des informations d'indication cibles utilisées pour indiquer le canal de travail indésirable; et envoyer les informations d'indication cibles à un point d'accès (AP), de sorte que l'AP détermine le canal de travail indésirable indiqué par une MBO-STA selon les informations d'indication cibles. Dans la présente invention, la MBO-STA peut indiquer précisément un canal dont on ne souhaite pas qu'il fonctionne en raison d'une distorsion d'intermodulation à l'AP, de sorte que l'AP puisse éviter la configuration du canal de travail indésirable pendant la configuration d'un canal de travail pour la MBO-STA, ce qui permet d'éviter l'effet indésirable provoqué par une distorsion d'intermodulation, et d'améliorer l'utilisation de canal de la MBO-STA
