Title (EN) PACKET DUPLICATION ACTIVATION SIGNALING
(FR) SIGNALISATION D'ACTIVATION DE DUPLICATION DE PAQUETS
Abstract:
(EN) A base station distributed unit receives information elements (IEs) from a base station central unit. The IEs comprise: at least one bearer configuration information element indicating that PDCP packet duplication is configured for at least one first bearer of a wireless device; and at least one information element indicating activation of the PDCP packet duplication of the at least one first bearer. The base station distributed unit transmits a medium access control control element indicating the activation of the PDCP packet duplication of the at least one first bearer to the wireless device in response to the at least one information element indicating the activation of the PDCP packet duplication. Based on the medium access control control element, the base station distributed unit receives: PDCP packets of the at least one first bearer; and duplicated PDCP packets of the at least one first bearer.
(FR) Une unité distribuée de station de base reçoit des éléments d'informations (IE) d'une unité centrale de station de base. Les IE comprennent : au moins des éléments d'informations de configuration de support indiquant qu'une duplication de paquets PDCP est configurée pour au moins un premier support d'un dispositif sans fil; et au moins un élément d'informations indiquant une activation de la duplication de paquet PDCP du ou des premiers supports. L'unité distribuée de station de base transmet un élément de commande d'accès au support, indiquant l'activation de la duplication de paquets PDCP du ou des premiers supports, au dispositif sans fil en réponse à l'indication, par le ou les éléments d'informations, de l'activation de la duplication de paquets PDCP. Sur la base de l'élément de commande d'accès au support, l'unité distribuée de station de base reçoit : des paquets PDCP du ou des premiers supports; et des paquets PDCP dupliqués du ou des premiers supports.
