Abstract
(EN)
A method for operating a first communication node in a wireless communication network may comprise: a step for measuring the channel busy ratio of a first channel; a step for allowing fallback transmission of a first frame in the first channel on the basis of information about the channel busy ratio of the first channel; a step for performing a channel sensing operation in the first channel and a second channel; and a step for performing fallback transmission of the first frame in the first channel when, as a result of the channel sensing operation, the state of the first channel is an idle state and the state of the second channel is a busy state.
(FR)
L’invention concerne un procédé d'exploitation d'un premier nœud de communication dans un réseau de communication sans fil. Le procédé peut comprendre : une étape consistant à mesurer le rapport d'occupation de canal d'un premier canal ; une étape pour permettre une transmission de secours d'une première trame dans le premier canal sur la base d'informations concernant le rapport d'occupation de canal du premier canal ; une étape consistant à effectuer une opération de détection de canal dans le premier canal et un second canal ; et une étape consistant à effectuer une transmission de secours de la première trame dans le premier canal lorsque, en résultat de l'opération de détection de canal, l'état du premier canal est un état de repos et l'état du second canal est un état occupé.
