Title
(EN) HYPRID AUTOMATIC REPEAT REQUEST FEEDBACK DESIGN FOR GRANT-FREE TRANSMISSION IN MOBILE COMMUNICATIONS
(FR) CONCEPTION DE RÉTROACTION DE REQUÊTE AUTOMATIQUE DE RÉPÉTITION HYBRIDE POUR UNE TRANSMISSION SANS AUTORISATION DANS DES COMMUNICATIONS MOBILES
Abstract
(EN)
Various solutions for hybrid automatic repeat request (HARQ) feedback design for grant-free transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may perform a grant-free transmission to transmit at least one of repetitions to a network node. The apparatus may receive a feedback from the network node. The apparatus may terminate the grant-free transmission after receiving the feedback. A part of the repetitions may not be transmitted after terminating the grant-free transmission.
(FR)
L'invention concerne diverses solutions de conception d'une rétroaction de requête automatique de répétition hybride (HARQ) relativement à un équipement d'utilisateur et un appareil de réseau dans des communications mobiles. Un appareil peut exécuter une transmission sans autorisation pour transmettre au moins une de répétitions à un nœud de réseau. L'appareil peut recevoir une rétroaction, du nœud de réseau. L'appareil peut mettre fin à la transmission sans autorisation après réception de la rétroaction. Une partie des répétitions peut ne pas être transmise après la fin de la transmission sans autorisation.
