Abstract

La présente invention concerne un procédé de transmission de données de dispositif à dispositif (D2D), un appareil, et un UE D2D. Le procédé consiste à : déterminer des informations d'indication de compression d'en-tête de protocole de convergence de données par paquets (PDCP), utilisées pour indiquer si un UE envoyant une communication D2D implémente un processus de compression d'en-tête PDCP d'une unité de données de protocole (PDU) PDCP; et envoyer les informations d'indication de compression d'en-tête PDCP à un UE recevant une communication D2D. La présente invention résout le problème lié, dans l'état de la technique, au fait qu'un UE recevant une communication D2D n'est pas apte à analyser correctement des données de communication D2D. L'invention permet quant à elle à un UE recevant une communication D2D de pouvoir analyser correctement des données de communication D2D via l'acquisition d'informations d'indication de compression d'en-tête PDCP.
