Title
(EN) ENABLING UPLINK ROUTING THAT SUPPORTS MULTI-CONNECTIVITY IN INTEGRATED ACCESS BACKHAUL NETWORKS
(FR) ACTIVATION D'UN ROUTAGE DE LIAISON MONTANTE QUI PREND EN CHARGE UNE MULTI-CONNECTIVITÉ DANS DES RÉSEAUX DE LIAISON TERRESTRE À ACCÈS INTÉGRÉ
Abstract
(EN)
A method performed by a network node operating as an Integrated Access Backhaul (IAB) node includes determining at least two parent nodes within a multi-hop IAB network. The IAB node receives an uplink routing configuration associated with a cell group configuration that identifies a selected one of the parent nodes. Based on the uplink routing configuration associated with the cell group configuration, packets are sent to at least one of the at least two parent nodes.
(FR)
Un procédé mis en œuvre par un nœud de réseau fonctionnant en tant que nœud de liaison terrestre à accès intégré (IAB) consiste à déterminer au moins deux nœuds parents dans un réseau IAB à sauts multiples. Le nœud IAB reçoit une configuration de routage de liaison montante associée à une configuration de groupe de cellules qui identifie un nœud sélectionné parmi les nœuds parents. Sur la base de la configuration de routage de liaison montante associée à la configuration de groupe de cellules, des paquets sont envoyés à au moins l'un des au moins deux nœuds parents.
