Title
(EN) METHOD AND APPARATUS FOR DEVICE-TO-DEVICE COMMUNICATION
(FR) PROCÉDÉ ET APPAREIL POUR UNE COMMUNICATION DE DISPOSITIF À DISPOSITIF
Abstract
(EN)
The subject application is related to a method and apparatus for Device-to-Device communication. A method for Device-to-Device communication includes transmitting a signal toward a group of user equipments (UEs); detecting a HARQ feedback signal accumulated by signal (s) from one or more UEs within the group of UEs; and transmitting a signal toward the group of UEs, wherein the UE and the group of UEs are configured to perform groupcast transmission.
(FR)
L'invention concerne un procédé et un appareil pour une communication de dispositif à dispositif. Un procédé de communication de dispositif à dispositif consiste à : transmettre un signal à un groupe d'équipements utilisateurs (UE) ; détecter un signal de rétroaction HARQ cumulé à partir d'un ou plusieurs signaux provenant d’un ou plusieurs UE du groupe d'UE ; et transmettre un signal au groupe d'UE, l'UE et le groupe d'UE étant configurés pour exécuter une transmission de diffusion de groupe.
