Title
(EN) DATA DUPLICATION OVER RADIO LINK CONTROL CHANNELS
(FR) DUPLICATION DE DONNÉES SUR DES CANAUX DE COMMANDE DE LIAISON RADIO
Abstract
(EN)
This disclosure describes methods, systems, and devices for efficient medium access control (MAC) control element (CE) signaling that controls uplink data duplication. In one example, a method involves generating a message including a MAC CE for indicating an activation or deactivation status of one or more radio link control (RLC) channels associated with packet data convergence protocol (PDCP) duplication. The method further involves encoding the message for transmission to a user equipment (UE).
(FR)
La présente invention concerne des procédés, des systèmes et des dispositifs pour une signalisation efficace d'élément de commande (CE) d'accès au support (MAC) qui commande la duplication de données de liaison montante. Dans un exemple, un procédé consiste à générer un message contenant un CE MAC pour indiquer un état d'activation ou de désactivation d'un ou plusieurs canaux de commande de liaison radio (RLC) associés à une duplication de protocole de convergence de données par paquets (PDCP). Le procédé consiste également à coder le message pour une transmission à un équipement utilisateur (UE).
