Abstract
(EN)
This disclosure provides systems, methods and apparatus for a user equipment (UE), operating in a shared spectrum in a connected state or an idle state, to receive a channel occupancy time structure information (COT-SI) which includes one or more of a COT duration, a COT end symbol, and a COT pause indication, in addition to slot format indication for one or more slots. Some aspects described herein define a hierarchical approach to COT structure information (COT-SI) signaling. For example, a UE may be configured with a set of short COT tables using remaining minimum system information (RMSI) signaling and may receive concatenation of COT-SI signaling identifying index values in a control channel corresponding to one or more of the set of COT tables. Based on receiving COT-SI signaling, the UE may communicate in accordance with an occurrence of a COT.

La présente invention concerne des systèmes, des procédés et un appareil pour un équipement utilisateur (UE), fonctionnant dans un spectre partagé dans un état connecté ou un état inactif, pour recevoir des informations de structure de temps d'occupation de canal (COT-SI) qui comprennent un ou plusieurs éléments parmi une durée de COT, un symbole de fin de COT et une indication de pause de COT, en plus de l'indication de format d'intervalle pour un ou plusieurs intervalles. Certains aspects de la présente invention définissent une approche hiérarchique pour la signalisation d'informations de structure de COT (COT-SI). Par exemple, un UE peut être conçu avec un ensemble de tables de COT courtes à l'aide d'une signalisation d'informations de système minimum restantes (RMSI) et peut recevoir une concaténation de signalisation de COT-SI identifiant des valeurs d'index dans un canal de commande correspondant à une ou plusieurs de l'ensemble de tables de COT. Sur la base de la réception d'une signalisation de COT-SI, l'UE peut communiquer en fonction d'une occurrence d'un COT.
