Title (EN) ON-DEMAND LISTEN-BEFORE-TALK
(FR) ÉCOUTER AVANT DE PARLER À LA DEMANDE
Abstract:
(EN) Methods, systems, and devices for wireless communications are described. A wireless device may determine an interference status of each beam configuration of a plurality of active beam configurations for a shared radio frequency spectrum band. The wireless device may determine a beam-specific listen-before-talk (LBT) requirement for each beam configuration of the plurality of active beam configurations based at least in part on the determined interference status of each beam configuration. The wireless device may selectively enable an LBT procedure on a per-beam basis according to the determined beam-specific LBT requirement for each beam configuration.
(FR) La présente invention concerne des procédés, des systèmes et des dispositifs de communications sans fil. Un dispositif sans fil peut déterminer un état d'interférence de chaque configuration de faisceau d'une pluralité de configurations de faisceau actif pour une bande de spectre radiofréquence partagée. Le dispositif sans fil peut déterminer un besoin en écouter avant de parler (LBT) spécifique au faisceau pour chaque configuration de faisceau de la pluralité de configurations de faisceau actif sur la base, au moins en partie, de l'état d'interférence déterminé de chaque configuration de faisceau. Le dispositif sans fil peut sélectivement permettre une procédure LBT par faisceau en fonction du besoin LBT spécifique au faisceau déterminée pour chaque configuration de faisceau.
