Abstract[English]
Various aspects of the present disclosure relate to a user equipment (UE) that acquires, from a base station, a sidelink (SL) grant that includes a channel occupancy time (COT) for part of an unlicensed spectrum allowing the acquiring UE to transmit SL control and data information to a secondary UE. The acquiring UE can also share the COT with the secondary UE, allowing the secondary UE to transmit SL control and data to the acquiring UE or another UE. The acquiring UE performs clear channel assessment (CCA) on one or more SL resources associated with the SL grant. The UE returns an SL hybrid automatic repeat request (HARQ) feedback to the base station based at least in part on a status of the CCA.[French]
Divers aspects de la présente divulgation concernent un équipement utilisateur (UE) qui acquiert, à partir d'une station de base, une autorisation de liaison latérale (SL) qui comprend un temps d'occupation de canal (COT) pour une partie d'un spectre sans licence permettant à l'UE acquéreur de transmettre une commande SL et des informations de données à un UE secondaire. L'UE acquéreur peut également partager le COT avec l'UE secondaire, ce qui permet à l'UE secondaire de transmettre une commande SL et des données à l'UE acquéreur ou à un autre UE. L'UE acquéreur effectue une évaluation de canal libre (CCA) sur une ou plusieurs ressources SL associées à l'autorisation SL. L'UE renvoie une rétroaction de demande de répétition automatique hybride (HARQ) SL à la station de base d’après au moins en partie un état de la CCA.
