Abstract

Des modes de réalisation de la présente divulgation concernent un procédé de communication, un dispositif de station, un dispositif de point d'accès, et un système de communication. Le procédé de communication de l'invention est appliqué à un de dispositif de station STA, et consiste à : lors de la réception d'une demande de partage d'opportunité de transmission inverse (RTXS) initiée par un dispositif de point d'accès AP, déterminer une première trame radio, la première trame radio comprenant des premières informations d'identification, et les premières informations d'identification étant utilisées pour identifier si la STA étend une opportunité de transmission (TXOP) obtenue ; et envoyer la première trame radio. De cette manière, lorsque la durée restante de la TXOP est insuffisante pour transmettre des données de service à temporaires/en rafale à faible retard dans la demande RTXS et pour transmettre des données de liaison montante de la STA à l'AP après que la transmission a été achevée, la TXOP est étendue, ce qui permet d'assurer la transmission de données de liaison montante interrompues ou retardées tout en garantissant de préférence la transmission des données de service temporaires/en rafale à faible retard, de réduire le retard de transmission de données de service à faible retard et d'augmenter le débit de transmission de données.
