Abstract
(EN) Apparatuses, methods, and systems are disclosed for performing channel occupancy time sensing. One method (900) includes receiving (902) information configuring a single channel occupancy time for multi-beam transmission in an unlicensed channel. The method (900) includes performing (904) sensing for the single channel occupancy time. The sensing includes: omni-directional sensing at a beginning of the single channel occupancy time; directional sensing on a plurality of beams at the beginning of the single channel occupancy time; directional sensing on the plurality of beams in a time domain multiplexing manner before each transmission based on a time gap between transmissions; or some combination thereof.
(FR) Sont décrits ici des appareils, des procédés et des systèmes mettant en oeuvre une détection de temps d'occupation de canal. Un procédé (900) consiste à recevoir (902) des informations configurant un temps d'occupation de canal unique pour une transmission multi-faisceau dans un canal sans licence. Le procédé (900) consiste à mettre en oeuvre une détection (904) du temps d'occupation de canal unique. La détection comprend : une détection omnidirectionnelle au début du temps d'occupation de canal unique ; une détection directionnelle sur une pluralité de faisceaux au début du temps d'occupation de canal unique ; une détection directionnelle sur la pluralité des faisceaux selon un mode de multiplexage dans le domaine temporel avant chaque transmission sur la base d'un intervalle de temps entre des transmissions ; ou une combinaison de celles-ci.
